Hi just wondering, can everybody contribute to the sdk via pull requests on gerrit?
david_dornseifer (Tue, 07 Feb 2017 02:59:19 GMT):
or better via commit / reviews on gerrit ;)
grapebaba (Tue, 07 Feb 2017 03:12:51 GMT):
@david_dornseifer actually pull requests is a notion in github, you can do same thing using gerrit

baohua (Fri, 10 Feb 2017 03:22:17 GMT):
especially there's a `examples` dir, as good starting place.
baohua (Fri, 10 Feb 2017 03:23:55 GMT):

=== Meeting End ===
latitiah (Fri, 10 Feb 2017 03:44:50 GMT):
Hi all! My apologies for missing the scrum meeting. I haven't forgotten. I have been working on the MVP issue (send_transaction_proposal). I've been delayed, but hope to have code pushed within the next week.
lafenicecc (Fri, 10 Feb 2017 04:02:01 GMT):
@latitiah Great! Please coordinate with @grapebaba , just in case of conflict

genggjh (Fri, 10 Feb 2017 07:27:33 GMT):
@baohua, I am reading the py sdk code, looks like the create_transaction_proposal does still not implemented yet, the related task had been marked done in the early of today. So, did i missing something?
baohua (Fri, 10 Feb 2017 07:28:17 GMT):
@genggjh can u help provide the task link?
genggjh (Fri, 10 Feb 2017 07:28:36 GMT):
https://jira.hyperledger.org/browse/FAB-1767
baohua (Fri, 10 Feb 2017 07:28:44 GMT):
let me see
baohua (Fri, 10 Feb 2017 07:29:19 GMT):
aha, i thought it was for create a deployment proposal? @latitiah
baohua (Fri, 10 Feb 2017 07:29:41 GMT):
@genggjh how do u think?
lafenicecc (Fri, 10 Feb 2017 07:33:03 GMT):
I thought create_deploy_proposal and create_transaction_proposal should be two subtasks?
baohua (Fri, 10 Feb 2017 07:34:07 GMT):
aha, then my mistake to close it. I will reopen.
lafenicecc (Fri, 10 Feb 2017 07:34:15 GMT):
And even create_deploy_proposal is not 100% done yet. "sign_proposal" is not done yet
lafenicecc (Fri, 10 Feb 2017 07:34:15 GMT):
And even create_deploy_proposal is not 100% done yet. "sign_proposal" is not done
baohua (Fri, 10 Feb 2017 07:34:45 GMT):
sure, re-open now. :)
baohua (Fri, 10 Feb 2017 07:35:18 GMT):
:rowboat:
genggjh (Fri, 10 Feb 2017 08:07:01 GMT):
ok
grapebaba (Fri, 10 Feb 2017 08:11:05 GMT):
是啊，也在看
grapebaba (Fri, 10 Feb 2017 08:11:33 GMT):
现在必须signed proposal才能send
grapebaba (Fri, 10 Feb 2017 08:12:17 GMT):
who is responsible for sign
baohua (Fri, 10 Feb 2017 08:41:13 GMT):
let's do them in parallel, with creating those apis first.
baohua (Fri, 10 Feb 2017 08:41:30 GMT):
@grapebaba I remember u and fan have done some crypto works?
baohua (Fri, 10 Feb 2017 08:42:10 GMT):
I saw node sdk have a cryptosuite to provide ecdsa and aes
grapebaba (Fri, 10 Feb 2017 08:42:10 GMT):
but i cannot test
baohua (Fri, 10 Feb 2017 08:42:36 GMT):
any problem with test?
grapebaba (Fri, 10 Feb 2017 08:43:12 GMT):
can it allow sending unsigned proposal?
grapebaba (Fri, 10 Feb 2017 08:43:22 GMT):
i suspect not
baohua (Fri, 10 Feb 2017 08:43:58 GMT):
cannot. before sending, we need a sign part.
baohua (Fri, 10 Feb 2017 08:44:43 GMT):
py sdk now already has a api/crypto module, was implemented by u or fan?
grapebaba (Fri, 10 Feb 2017 08:45:09 GMT):
i checked latest code
grapebaba (Fri, 10 Feb 2017 08:45:11 GMT):
node
grapebaba (Fri, 10 Feb 2017 08:45:27 GMT):
seems we should implement msp first
baohua (Fri, 10 Feb 2017 08:46:28 GMT):
yeap, then let's work on the msp part first. would u like to be the task driver :)
grapebaba (Fri, 10 Feb 2017 08:46:54 GMT):
ok
baohua (Fri, 10 Feb 2017 08:47:26 GMT):
thanks, pls help drive the progress. I will also work on it.
grapebaba (Fri, 10 Feb 2017 08:47:54 GMT):
i will submit a structure of sending proposal first, then take msp impl
baohua (Fri, 10 Feb 2017 08:49:14 GMT):
thanks. yes, let's first create those framework, then fill the implementation together.

david_dornseifer (Tue, 14 Feb 2017 18:22:34 GMT):
Hi, what is the idea about the missing tox dependency? you just want to run the tests in the fabric-sdk-py container?
baohua (Wed, 15 Feb 2017 01:37:55 GMT):
@david_dornseifer which dependency is missing? Currently we run the ci tests directly in the ci vm. Thanks!
david_dornseifer (Wed, 15 Feb 2017 01:40:12 GMT):
ok, thx - was just wondering since that tox was not mentioned in the test-requirements and it is missing when you execute the make check outside the container
baohua (Wed, 15 Feb 2017 01:59:14 GMT):
pls have a look at the tox.ini
baohua (Wed, 15 Feb 2017 01:59:31 GMT):
there's some basic dependency description :)
baohua (Thu, 16 Feb 2017 03:11:22 GMT):
@all Dear all, since most of the team is focusing on the MVP implementation this week, will cancel the meeting tmr, let's collaborate online if any issues. Everyone pls help contribute and review the patchsets in time: https://gerrit.hyperledger.org/r/#/q/project:fabric-sdk-py. Thanks!

Hi all, I will not be able to attend scrum tonight. I'm trying to finish up some behave test implementations, so I'll be focusing on that tonight. (BTW: great job on 6405! I had some minor comments, but I was a little late getting them in before it was merged.) :)

item #3: MVP design. any update @lafenicecc
lafenicecc (Fri, 24 Feb 2017 03:10:11 GMT):
Hi
lafenicecc (Fri, 24 Feb 2017 03:10:32 GMT):
In the last 2 weeks, we did some ... inevitable works to carry the MVP work forward
lafenicecc (Fri, 24 Feb 2017 03:10:51 GMT):
for example, the user module, identity and msp module, crypto sign...
lafenicecc (Fri, 24 Feb 2017 03:10:59 GMT):
Thanks for all your help!
lafenicecc (Fri, 24 Feb 2017 03:11:34 GMT):
Now we have removed some of the obstacles, but still a lot ahead
lafenicecc (Fri, 24 Feb 2017 03:12:19 GMT):
@grapebaba any plans or comments about the current work?
grapebaba (Fri, 24 Feb 2017 03:12:44 GMT):
for the e2e test
grapebaba (Fri, 24 Feb 2017 03:13:17 GMT):
we still need preventmalleability feature and complete MSP feature
baohua (Fri, 24 Feb 2017 03:13:38 GMT):
@tcz001 said to help on this feature
baohua (Fri, 24 Feb 2017 03:13:52 GMT):
are we blocked on that now, to finish the MVP?
grapebaba (Fri, 24 Feb 2017 03:14:13 GMT):
i think so
lafenicecc (Fri, 24 Feb 2017 03:14:30 GMT):
why blocked by preventmalleability?
baohua (Fri, 24 Feb 2017 03:14:40 GMT):
assume the users are not doing evil first?
grapebaba (Fri, 24 Feb 2017 03:15:06 GMT):
i am not quite sure
grapebaba (Fri, 24 Feb 2017 03:15:24 GMT):
but i saw the code will change the signature
grapebaba (Fri, 24 Feb 2017 03:15:37 GMT):
in node SDK
grapebaba (Fri, 24 Feb 2017 03:15:54 GMT):
i am not sure if it will fail in server side
baohua (Fri, 24 Feb 2017 03:16:21 GMT):
IMHO, i guess we can ignore the preventmalleability feature for the e2e currently, as it's only for security. @grapebaba can u help make sure the code change in node sdk? whether it's matter to the e2e test?
grapebaba (Fri, 24 Feb 2017 03:16:25 GMT):
another we missing signing_identity serialize() method
lafenicecc (Fri, 24 Feb 2017 03:17:23 GMT):
@SeeGo can u help look at this method?
lafenicecc (Fri, 24 Feb 2017 03:18:14 GMT):
is it the only block before we can send the proposal and get response? @grapebaba
baohua (Fri, 24 Feb 2017 03:18:46 GMT):
i suppose @SeeGo will be back later :):cat:
grapebaba (Fri, 24 Feb 2017 03:19:36 GMT):
seems
baohua (Fri, 24 Feb 2017 03:20:03 GMT):
@ray feel free to pick tasks, too. now we are finishing the MVP with e2e testing :)
baohua (Fri, 24 Feb 2017 03:20:20 GMT):
OK, any more comments on the MVP work?
lafenicecc (Fri, 24 Feb 2017 03:20:32 GMT):
yea, i can help explain the work, feel free to ask me anything anytime
baohua (Fri, 24 Feb 2017 03:20:33 GMT):

ray (Fri, 24 Feb 2017 03:20:53 GMT):

baohua (Fri, 24 Feb 2017 03:20:56 GMT):
ok, cool~
baohua (Fri, 24 Feb 2017 03:21:11 GMT):
SDK spec can be found at ttps://docs.google.com/document/d/1R5RtIBMW9fZpli37E5Li5_Q9ve3BnQ4q3gWmGZj6Sv4
baohua (Fri, 24 Feb 2017 03:21:33 GMT):
although some minor differ from that. can also look at the node sdk as reference.
baohua (Fri, 24 Feb 2017 03:21:53 GMT):
but we can be flexible to adopt the pythonic way :snake:
ray (Fri, 24 Feb 2017 03:22:25 GMT):
Thanks, will do some investigation first. I love :snake:

baohua (Fri, 24 Feb 2017 03:25:26 GMT):
OK. any other issue to discuss today?
grapebaba (Fri, 24 Feb 2017 03:26:01 GMT):
```func (csp *impl) verifyECDSA(k *ecdsa.PublicKey, signature, digest []byte, opts bccsp.SignerOpts) (valid bool, err error) {
r, s, err := unmarshalECDSASignature(signature)
if err != nil {
return false, fmt.Errorf("Failed unmashalling signature [%s]", err)
}
// check for low-S
halfOrder, ok := curveHalfOrders[k.Curve]
if !ok {
return false, fmt.Errorf("Curve not recognized [%s]", k.Curve)
}
// If s > halfOrder Then
if s.Cmp(halfOrder) == 1 {
return false, fmt.Errorf("Invalid S. Must be smaller than half the order [%s][%s].", s, halfOrder)
}
return ecdsa.Verify(k, digest, r, s), nil
}```
grapebaba (Fri, 24 Feb 2017 03:27:46 GMT):
i still suspect preventmalleability will block
baohua (Fri, 24 Feb 2017 03:28:54 GMT):
aha, let's ask @tcz001 to help confirm. besides that, let's finish other part soon.
baohua (Fri, 24 Feb 2017 03:29:45 GMT):
signing_identity serialize() method, @ray i may ask u to pick up this task as a practice on hand :)
grapebaba (Fri, 24 Feb 2017 03:30:09 GMT):
i invite @muralisr to help us review the tasks for MVP

Any idea how to solve the error?
aratic (Sun, 26 Feb 2017 05:36:06 GMT):
would you please print more section of the build log? or you may try to "pip install pylint" if you found some command missing at the very first line of the error log

make sure you got both python tox pylint docker-compose installed, and try make clean, and then make check / make image ?
aratic (Sun, 26 Feb 2017 10:06:38 GMT):
there is a wierd "image not found", i belive it do fetch a library/python docker image in the process, and some path / prefix error, but since you are using macOs, i'm not familiar with the details
baohua (Sun, 26 Feb 2017 10:22:38 GMT):
@melek u need install following softwares: python, Docker and docker-compose in the server first.

@grapebaba @lafenicecc
baohua (Fri, 03 Mar 2017 03:05:33 GMT):
will u help sync the status of our mvp?
baohua (Fri, 03 Mar 2017 03:05:56 GMT):
i saw lots of progress, need to clarify the next steps.
lafenicecc (Fri, 03 Mar 2017 03:06:19 GMT):
how's the signature issue? @grapebaba
grapebaba (Fri, 03 Mar 2017 03:06:31 GMT):
still block
baohua (Fri, 03 Mar 2017 03:07:07 GMT):
guess @tcz001 is working on this?
grapebaba (Fri, 03 Mar 2017 03:07:24 GMT):
yeah, hope he can help
baohua (Fri, 03 Mar 2017 03:07:40 GMT):
great, pls keep syncing
baohua (Fri, 03 Mar 2017 03:07:52 GMT):
other issues to do for mvp?
lafenicecc (Fri, 03 Mar 2017 03:08:05 GMT):
how about the protos path issue?
grapebaba (Fri, 03 Mar 2017 03:08:25 GMT):
alreay fixed
lafenicecc (Fri, 03 Mar 2017 03:08:35 GMT):
:thumbsup:
baohua (Fri, 03 Mar 2017 03:09:02 GMT):
so now we can pickup protos from fabric code directly without any modification?
baohua (Fri, 03 Mar 2017 03:09:08 GMT):
great!
grapebaba (Fri, 03 Mar 2017 03:09:10 GMT):
no
baohua (Fri, 03 Mar 2017 03:09:26 GMT):
ooops
baohua (Fri, 03 Mar 2017 03:09:34 GMT):
:penguin:
baohua (Fri, 03 Mar 2017 03:10:12 GMT):
aha, we still need to use abstract path in the import `xxxx`
baohua (Fri, 03 Mar 2017 03:10:28 GMT):
e.g., `import "hfc/protos/common/common.proto";`
baohua (Fri, 03 Mar 2017 03:10:43 GMT):
but the `package` should keep unchanged
baohua (Fri, 03 Mar 2017 03:10:47 GMT):
correct?
grapebaba (Fri, 03 Mar 2017 03:11:14 GMT):
yes
baohua (Fri, 03 Mar 2017 03:11:43 GMT):
ok. @ray i remember u've helped a serialization item last week?
ray (Fri, 03 Mar 2017 03:12:05 GMT):
Yes, that's already merged into master
baohua (Fri, 03 Mar 2017 03:12:26 GMT):
thanks, and feel free to pick other tasks: https://jira.hyperledger.org/secure/RapidBoard.jspa?rapidView=85
baohua (Fri, 03 Mar 2017 03:12:46 GMT):
Also, welcome to help on new ones like refining the documentation.
baohua (Fri, 03 Mar 2017 03:12:59 GMT):
documentation is complaining too much recently on the fabric project :(
baohua (Fri, 03 Mar 2017 03:12:59 GMT):
documentation is complained too much recently on the fabric project :(
baohua (Fri, 03 Mar 2017 03:13:50 GMT):
i would encourage everyone too to help on the documentation, it's very important for open-source projects!
lafenicecc (Fri, 03 Mar 2017 03:14:32 GMT):
what documentation, give an example?
baohua (Fri, 03 Mar 2017 03:14:50 GMT):
e.g., we have making lots of change on the structure.
baohua (Fri, 03 Mar 2017 03:15:09 GMT):
some notes on the design structure/how to use the mvp would be appreciated.
baohua (Fri, 03 Mar 2017 03:15:26 GMT):
no users wanna learn how to use the software from reading the source code.
baohua (Fri, 03 Mar 2017 03:15:47 GMT):
although i guess this will lead to a better understanding :snail:
baohua (Fri, 03 Mar 2017 03:16:10 GMT):
@lafenicecc btw, would u like to help check the jira tasks and confirm the current status are correct?
lafenicecc (Fri, 03 Mar 2017 03:16:21 GMT):
yes
baohua (Fri, 03 Mar 2017 03:16:25 GMT):
thanks!
ray (Fri, 03 Mar 2017 03:16:38 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=PGDXszDadXreYEGmx) @baohua sure, and I am helping track the ca modules recently, will sync if any progress is made
baohua (Fri, 03 Mar 2017 03:16:52 GMT):
thanks ray!
lafenicecc (Fri, 03 Mar 2017 03:17:29 GMT):
The fabric and node sdk codes are changing fast. I suppose each task owner has the responsibility of ... keep it up-to-date?
baohua (Fri, 03 Mar 2017 03:18:20 GMT):
the fabric code is going stable now. but the node sdk.... i guess we will be fine after finishing the mvp with minor updates. good suggestion anyway.
lafenicecc (Fri, 03 Mar 2017 03:18:32 GMT):
ok
baohua (Fri, 03 Mar 2017 03:18:37 GMT):
ok, item#4. the sdk link is at https://docs.google.com/document/d/1R5RtIBMW9fZpli37E5Li5_Q9ve3BnQ4q3gWmGZj6Sv4
baohua (Fri, 03 Mar 2017 03:18:50 GMT):
hope everyone already be familiar with that.
baohua (Fri, 03 Mar 2017 03:19:04 GMT):
#item 5: other issues?
baohua (Fri, 03 Mar 2017 03:19:33 GMT):
some not-good-news, our sdk-py summer internship proposal seems not be accepted by LF.
baohua (Fri, 03 Mar 2017 03:20:02 GMT):
however, we can work around in other ways, e.g., let's share in those campus events. specially, this hackathon in shanghai.
baohua (Fri, 03 Mar 2017 03:21:01 GMT):
and for this, the documentation is important, again.:wolf:
baohua (Fri, 03 Mar 2017 03:21:01 GMT):
and for this, the documentation is important, again. :wolf:
grapebaba (Fri, 03 Mar 2017 03:21:02 GMT):
I have a design change in recent mvp patch
grapebaba (Fri, 03 Mar 2017 03:21:32 GMT):
not follow node SDK, maybe we could talk
baohua (Fri, 03 Mar 2017 03:21:47 GMT):
exactly, the node sdk is a reference.
baohua (Fri, 03 Mar 2017 03:22:01 GMT):
let's make the py sdk better with those pythonic magics
baohua (Fri, 03 Mar 2017 03:22:13 GMT):
:trumpet:
grapebaba (Fri, 03 Mar 2017 03:22:14 GMT):
the most difference is about Chain Object
baohua (Fri, 03 Mar 2017 03:22:36 GMT):
sure, would u like to discuss here or offline, both are fine with me
grapebaba (Fri, 03 Mar 2017 03:23:09 GMT):
node SDK put createchannel method in the Chain Object
baohua (Fri, 03 Mar 2017 03:23:36 GMT):
yes?
grapebaba (Fri, 03 Mar 2017 03:24:00 GMT):
however i understand the multiple channels actual multiple chains
grapebaba (Fri, 03 Mar 2017 03:25:02 GMT):
So that i use chain object per channel
grapebaba (Fri, 03 Mar 2017 03:25:40 GMT):
this is the main difference
baohua (Fri, 03 Mar 2017 03:26:40 GMT):
ok, well, i guess this is a definition problem. currently we agree each channel has separate ledger. we can discuss this more whether pick the 1chain-1channel model.
baohua (Fri, 03 Mar 2017 03:27:26 GMT):
but definitely we have 1 network :)
baohua (Fri, 03 Mar 2017 03:27:37 GMT):
Ok, any more issues to discuss today?
baohua (Fri, 03 Mar 2017 03:28:33 GMT):
Ok, then will end the meeting, thanks everyone and have nice weekend!:basketball_player:
ray (Fri, 03 Mar 2017 03:28:53 GMT):
have a good weekend :-)

oops, the at-all is not allowed in this room..
baohua (Thu, 16 Mar 2017 09:18:40 GMT):
i tried the at-here, it works
baohua (Thu, 16 Mar 2017 09:18:54 GMT):
only at-all has problem now
rjones (Thu, 16 Mar 2017 09:28:16 GMT):
I don't see a distinct property for that. is at-here good enough?
baohua (Fri, 17 Mar 2017 00:54:57 GMT):
let's use the at-here feature first, thanks for the help, @rjones !
baohua (Fri, 17 Mar 2017 02:46:05 GMT):

MVP remaining tasks discussion. @lafenicecc @grapebaba any update?
baohua (Fri, 17 Mar 2017 03:05:19 GMT):
what do we still need?
ray (Fri, 17 Mar 2017 03:06:17 GMT):
I see send_tx and create_tx tasks are still unassigned
lafenicecc (Fri, 17 Mar 2017 03:06:53 GMT):
the instantiate and invoke test are skipped, anything not done yet? @grapebaba
baohua (Fri, 17 Mar 2017 03:07:26 GMT):
i think the create_tx has been finished? @ray which jira task? can u send the link
lafenicecc (Fri, 17 Mar 2017 03:08:01 GMT):
FAB-1768 and 1769, i suppose :grin:
ray (Fri, 17 Mar 2017 03:08:43 GMT):
yep 1768 and 1769
grapebaba (Fri, 17 Mar 2017 03:09:04 GMT):
right now, i just pass send tx proposal test for install chaincode
baohua (Fri, 17 Mar 2017 03:09:10 GMT):
i suppose grapebaba and I have finished the create_transaction part?
grapebaba (Fri, 17 Mar 2017 03:09:19 GMT):
actually we behind a lot
baohua (Fri, 17 Mar 2017 03:09:51 GMT):
so the create_tx part is done, we are working on the send_tx part?
baohua (Fri, 17 Mar 2017 03:10:04 GMT):
am i correct?
grapebaba (Fri, 17 Mar 2017 03:10:31 GMT):
create_tx may be not a public method
grapebaba (Fri, 17 Mar 2017 03:11:12 GMT):
refer to node and java
lafenicecc (Fri, 17 Mar 2017 03:11:21 GMT):
Any help do u need? like track with latest changes of fabric or node-sdk?
baohua (Fri, 17 Mar 2017 03:11:43 GMT):
ok, seems we still need some effort. any volunteers to help improve this two functions? @lafenicecc @ray
grapebaba (Fri, 17 Mar 2017 03:12:30 GMT):
i will take send tx and finish whole install process first
baohua (Fri, 17 Mar 2017 03:13:07 GMT):
thanks, then will assign 1768 to @lafenicecc and 1769 to @grapebaba first. while other people will help on these two remaining work.
baohua (Fri, 17 Mar 2017 03:13:18 GMT):
Let's target to finish MVP before end of March!
lafenicecc (Fri, 17 Mar 2017 03:13:19 GMT):
ok
baohua (Fri, 17 Mar 2017 03:13:58 GMT):

OK. sdk spec is there: https://docs.google.com/document/d/1R5RtIBMW9fZpli37E5Li5_Q9ve3BnQ4q3gWmGZj6Sv4
WeiHu (Fri, 17 Mar 2017 03:14:51 GMT):
of course:smiley:
baohua (Fri, 17 Mar 2017 03:15:14 GMT):
next item: thanks to ray, he has update the wiki page using doku wiki grammar, for stable rending.
ray (Fri, 17 Mar 2017 03:15:15 GMT):
So it's in public domain now
baohua (Fri, 17 Mar 2017 03:15:24 GMT):
pls feel free to report problems in wiki
ray (Fri, 17 Mar 2017 03:15:46 GMT):
I mean the sdk spec
baohua (Fri, 17 Mar 2017 03:16:00 GMT):
yeap, already open for a while
baohua (Fri, 17 Mar 2017 03:16:13 GMT):
somehow a little out-of-date with fabric 1.0
baohua (Fri, 17 Mar 2017 03:16:51 GMT):
and i have to say again. documentation is really important for open-source projects.
baohua (Fri, 17 Mar 2017 03:17:04 GMT):
even more important than code sometimes :)
baohua (Fri, 17 Mar 2017 03:17:20 GMT):
OK.
baohua (Fri, 17 Mar 2017 03:17:28 GMT):
any comments till now?
baohua (Fri, 17 Mar 2017 03:18:05 GMT):
OK, exciting moment! Welcome for new contributor: Wei Hu from Hyperchain!
baohua (Fri, 17 Mar 2017 03:18:20 GMT):
@WeiHu would u like to give a brief? to meet each other :)
ray (Fri, 17 Mar 2017 03:18:29 GMT):

really glad to join the group and make contribution~ i'm from hyperchain, let's make the project done together~
baohua (Fri, 17 Mar 2017 03:20:27 GMT):
thanks, definitely we need everyone's hand!
WeiHu (Fri, 17 Mar 2017 03:20:28 GMT):
:stuck_out_tongue:
baohua (Fri, 17 Mar 2017 03:20:43 GMT):
OK, next item

:clap:
baohua (Fri, 17 Mar 2017 03:20:55 GMT):
There is a new go sdk proposed to the community in yesterday TSC meeting.
baohua (Fri, 17 Mar 2017 03:21:25 GMT):
glad we have more sdk now. but somehow not sure how to use this go sdk, maybe not in web apps.
baohua (Fri, 17 Mar 2017 03:22:32 GMT):
And some guy tells they are trying to deploy fabric on Raspberry pie（树莓派）, this is interesting ~~
ray (Fri, 17 Mar 2017 03:22:32 GMT):
I see a hot mailing list thread discussing the sub-project proposal etc.
grapebaba (Fri, 17 Mar 2017 03:22:46 GMT):
go sdk is very good
baohua (Fri, 17 Mar 2017 03:22:52 GMT):
yeap, this topics has been arised several times...
baohua (Fri, 17 Mar 2017 03:22:52 GMT):
yeap, this topic has been arised several times...
WeiHu (Fri, 17 Mar 2017 03:23:11 GMT):
is it approved?
grapebaba (Fri, 17 Mar 2017 03:23:13 GMT):
right now, there are some tools such as configtx
baohua (Fri, 17 Mar 2017 03:23:28 GMT):
i only wanna we have more efficient collaboration method, no matter how to organize...
baohua (Fri, 17 Mar 2017 03:23:35 GMT):
yeap, configtxgen
grapebaba (Fri, 17 Mar 2017 03:23:44 GMT):
it can invoke it native
baohua (Fri, 17 Mar 2017 03:23:52 GMT):
but it can be just inside the fabric...
grapebaba (Fri, 17 Mar 2017 03:24:18 GMT):
but how can use in client side
baohua (Fri, 17 Mar 2017 03:24:42 GMT):
yeap, the interesting question is what kind of client may wanna pick Golang now....
grapebaba (Fri, 17 Mar 2017 03:25:01 GMT):
me
grapebaba (Fri, 17 Mar 2017 03:25:07 GMT):
:)
WeiHu (Fri, 17 Mar 2017 03:25:08 GMT):
web?
baohua (Fri, 17 Mar 2017 03:25:09 GMT):
i know golang can provide web... backend people still like java :(
baohua (Fri, 17 Mar 2017 03:25:33 GMT):
personally i like golang, but it may needs more time to teach people.
baohua (Fri, 17 Mar 2017 03:25:33 GMT):
personally i like golang, but it may need more time to teach people.
WeiHu (Fri, 17 Mar 2017 03:25:42 GMT):
golang is becoming more populate i think
grapebaba (Fri, 17 Mar 2017 03:25:54 GMT):
no, i don't like use golang for web
baohua (Fri, 17 Mar 2017 03:26:21 GMT):
haha, let's see, i believe in future there will be 3 languages: Java(Script), Python, and Golang --> JPG@@
WeiHu (Fri, 17 Mar 2017 03:26:44 GMT):
:joy:
baohua (Fri, 17 Mar 2017 03:26:47 GMT):
:airplane_arriving:
grapebaba (Fri, 17 Mar 2017 03:27:04 GMT):
web should be dominate by javascript
baohua (Fri, 17 Mar 2017 03:27:05 GMT):
last time at PyCon i threw this opinion
grapebaba (Fri, 17 Mar 2017 03:27:08 GMT):
guess
baohua (Fri, 17 Mar 2017 03:27:25 GMT):
ok, we have 3 minutes remaining, any more issues to discuss today?
baohua (Fri, 17 Mar 2017 03:27:52 GMT):
programming language/tool battle is always popular.....
ray (Fri, 17 Mar 2017 03:28:11 GMT):
and editors battle
baohua (Fri, 17 Mar 2017 03:28:27 GMT):
Ok, if there's no more issue, we will end the meeting...
baohua (Fri, 17 Mar 2017 03:28:51 GMT):
Thanks everyone, have a nice weekend!

grapebaba (Fri, 17 Mar 2017 03:30:53 GMT):
we need implement all these features
baohua (Fri, 17 Mar 2017 03:31:03 GMT):
let's fight for a e2e!
grapebaba (Fri, 17 Mar 2017 03:31:10 GMT):
you may create more tasks
baohua (Fri, 17 Mar 2017 03:31:31 GMT):
exactly, and everyone, pls feel free to use jira to create/update tasks.
baohua (Fri, 17 Mar 2017 03:33:12 GMT):
watching video, nice demo
ray (Fri, 17 Mar 2017 03:35:09 GMT):
he's using vagrant
baohua (Fri, 17 Mar 2017 03:36:34 GMT):
yeap, but vagrant is just providing a vm env for docker, as a Docker Host
baohua (Fri, 17 Mar 2017 03:36:48 GMT):
https://gerrit.hyperledger.org/r/#/c/7291/
ray (Fri, 17 Mar 2017 03:37:06 GMT):
Yep somehow I like this way too.. docker in vagrant vm..
grapebaba (Fri, 17 Mar 2017 04:27:35 GMT):
forget to say, our test coverage is very low
rjones (Fri, 17 Mar 2017 05:44:22 GMT):
Has left the channel.
baohua (Fri, 17 Mar 2017 06:23:36 GMT):
@grapebaba pls help create a jira task item on this, we need to improve it...

baohua (Fri, 24 Mar 2017 03:09:40 GMT):
@camelbeck will give u 5 mins at last for self-brief. :)
camelbeck (Fri, 24 Mar 2017 03:09:51 GMT):
sure
baohua (Fri, 24 Mar 2017 03:10:12 GMT):
@grapebaba can u sync and indicate what items we still need people to help?
baohua (Fri, 24 Mar 2017 03:10:29 GMT):
:penguin:
grapebaba (Fri, 24 Mar 2017 03:10:45 GMT):
sorry, this week is busy so that no progress for 1769
baohua (Fri, 24 Mar 2017 03:12:11 GMT):
ok, do we need more people on 1769? kai
baohua (Fri, 24 Mar 2017 03:12:55 GMT):
@grapebaba
grapebaba (Fri, 24 Mar 2017 03:12:58 GMT):
no, will catch up next week
baohua (Fri, 24 Mar 2017 03:13:02 GMT):
thanks
lafenicecc (Fri, 24 Mar 2017 03:13:27 GMT):
do we need to add an e2e example, like node-sdk did?
baohua (Fri, 24 Mar 2017 03:13:40 GMT):
exactly @ray would u like to start writing the e2e test case?
grapebaba (Fri, 24 Mar 2017 03:13:56 GMT):
+1
baohua (Fri, 24 Mar 2017 03:14:07 GMT):
and @WeiHu can help, i suggest.
ray (Fri, 24 Mar 2017 03:14:27 GMT):
ok I will pick this together with Wei
WeiHu (Fri, 24 Mar 2017 03:14:31 GMT):
ok
grapebaba (Fri, 24 Mar 2017 03:14:36 GMT):
maybe one thing we can discuss
lafenicecc (Fri, 24 Mar 2017 03:14:46 GMT):
i'll add a jira task
baohua (Fri, 24 Mar 2017 03:14:55 GMT):
thanks, @lafenicecc pls help create a jira task.
baohua (Fri, 24 Mar 2017 03:15:07 GMT):
sure, kai
grapebaba (Fri, 24 Mar 2017 03:15:46 GMT):
now i introduce rxpy lib for handle parallel invoke multiple endorers
grapebaba (Fri, 24 Mar 2017 03:16:01 GMT):
but it may be not usual
baohua (Fri, 24 Mar 2017 03:16:05 GMT):
yeap, saw it
grapebaba (Fri, 24 Mar 2017 03:16:22 GMT):
anyone knows other options
baohua (Fri, 24 Mar 2017 03:16:55 GMT):
i guess rxpy is suitable for this case, but not sure how's the perf gurantee
baohua (Fri, 24 Mar 2017 03:17:24 GMT):
otherwise, will use thread/event mode with more complicated code, i suppose
ray (Fri, 24 Mar 2017 03:18:11 GMT):
https://github.com/ReactiveX/RxPY this lib you guys are talking about, right?
baohua (Fri, 24 Mar 2017 03:18:17 GMT):
yeap
grapebaba (Fri, 24 Mar 2017 03:18:19 GMT):
yes
baohua (Fri, 24 Mar 2017 03:18:32 GMT):
and i suggest we do not optimize too earlier :)
baohua (Fri, 24 Mar 2017 03:18:47 GMT):
so the code can work, that's rule #0!
grapebaba (Fri, 24 Mar 2017 03:19:10 GMT):
ok
grapebaba (Fri, 24 Mar 2017 03:19:38 GMT):
however need guys familiar the API
grapebaba (Fri, 24 Mar 2017 03:19:58 GMT):
it is more like RxJS
baohua (Fri, 24 Mar 2017 03:20:08 GMT):
yeap that's learning curve
baohua (Fri, 24 Mar 2017 03:20:36 GMT):
i would suggest we keep using it first to finish the MVP, then see if there's problem in practice. how do u guys think?
grapebaba (Fri, 24 Mar 2017 03:20:53 GMT):
yeah
ray (Fri, 24 Mar 2017 03:21:08 GMT):
I agree with it
baohua (Fri, 24 Mar 2017 03:21:09 GMT):
and, maybe kai can help write some notes in the doc, introducing the basic apis and best-practice.
grapebaba (Fri, 24 Mar 2017 03:21:19 GMT):
sure
baohua (Fri, 24 Mar 2017 03:21:24 GMT):
that would be even cooler! :violin:
baohua (Fri, 24 Mar 2017 03:22:01 GMT):
OK, sdk spec link again: https://docs.google.com/document/d/1R5RtIBMW9fZpli37E5Li5_Q9ve3BnQ4q3gWmGZj6Sv4. suggest the new comer have a look @camelbeck
camelbeck (Fri, 24 Mar 2017 03:22:13 GMT):
you guys did great work, :thumbsup:
camelbeck (Fri, 24 Mar 2017 03:22:35 GMT):
no problem
baohua (Fri, 24 Mar 2017 03:22:37 GMT):
and there's some out-of-dated content in the spec. the code is the final rule. we have the java/nodesdk now.
camelbeck (Fri, 24 Mar 2017 03:22:44 GMT):
maybe i can start with it
baohua (Fri, 24 Mar 2017 03:22:54 GMT):
#item 6: test coverage discussion
baohua (Fri, 24 Mar 2017 03:23:06 GMT):
@camelbeck aha, sure.
grapebaba (Fri, 24 Mar 2017 03:23:29 GMT):
i think first we can add a coverage report lib in build
baohua (Fri, 24 Mar 2017 03:23:30 GMT):
any comments on #6? is it good time to start this discussion now?
ray (Fri, 24 Mar 2017 03:23:45 GMT):
agree with kai
baohua (Fri, 24 Mar 2017 03:24:13 GMT):
sure, any suggest candidate lib to use?
baohua (Fri, 24 Mar 2017 03:24:13 GMT):
sure, any suggested candidate lib to use?
grapebaba (Fri, 24 Mar 2017 03:24:50 GMT):
could add a task first
baohua (Fri, 24 Mar 2017 03:24:58 GMT):
@camelbeck are u familiar with the test coverage tool?
grapebaba (Fri, 24 Mar 2017 03:25:08 GMT):
owner can help investigate
baohua (Fri, 24 Mar 2017 03:25:16 GMT):
it should be not that difficult to learn.
baohua (Fri, 24 Mar 2017 03:25:28 GMT):
@grapebaba sure, create the issue first.
camelbeck (Fri, 24 Mar 2017 03:25:49 GMT):
sorry, have no knowledge about it, does it easy to learn?
baohua (Fri, 24 Mar 2017 03:25:56 GMT):
and maybe @camelbeck can pick that as the starting job.
baohua (Fri, 24 Mar 2017 03:26:12 GMT):
aha, python world is always easy to get on hand.
baohua (Fri, 24 Mar 2017 03:26:27 GMT):
u can do some investigation first
camelbeck (Fri, 24 Mar 2017 03:26:38 GMT):
ok, i will have a try
baohua (Fri, 24 Mar 2017 03:26:42 GMT):
Thanks!
camelbeck (Fri, 24 Mar 2017 03:26:52 GMT):

Hi, everyone, self intro: li chao, now working in IBM CSL on mainframe os rletated development.
camelbeck (Fri, 24 Mar 2017 03:27:47 GMT):
Previously, have studied fabric source code from chaincode view.
camelbeck (Fri, 24 Mar 2017 03:28:08 GMT):
And now I have some intersts in open source, I think this project may be a good start for me.

baohua (Fri, 24 Mar 2017 03:30:26 GMT):
so, come on, show urself and do something, also to everyone~~
camelbeck (Fri, 24 Mar 2017 03:30:39 GMT):

camelbeck (Mon, 03 Apr 2017 01:45:40 GMT):
Anyone encounters the situation that the unittest is stuck in test/unit/keyvaluestore_test.py execution? I find it will happen in most cases.
grapebaba (Mon, 03 Apr 2017 01:55:52 GMT):
What's the error? Can you paste the log?
camelbeck (Mon, 03 Apr 2017 01:57:44 GMT):
you can find the log here: https://logs.hyperledger.org/jobbuilder/vex-yul-hyp-jenkins-1/fabric-sdk-py-verify-x86_64/95/
grapebaba (Mon, 03 Apr 2017 06:05:20 GMT):
it seems that CI env not stable sometimes
grapebaba (Mon, 03 Apr 2017 06:05:53 GMT):
try 'reverify' in comment and trigger again
camelbeck (Mon, 03 Apr 2017 06:06:52 GMT):
thanks, i will have a try
grapebaba (Mon, 03 Apr 2017 06:10:36 GMT):
already done for this patch
grapebaba (Mon, 03 Apr 2017 06:14:15 GMT):
@camelbeck not sure what is the difference between coverage and pytest-cov, now we combine these two lib or only use pytest-cov?
camelbeck (Mon, 03 Apr 2017 07:46:17 GMT):
Great!!! Thanks @grapebaba ! For pytest-cov and coverage, I just want to separate the work of coverage running and reporting, and I would like the coverage report to be based on the combined result from different virtualenvs. So far, I have not found pytest-cov can do such work by itself. Thus, I use both these two. Besides, I wonder whether pytest-cov depends on coverage. I will do further investigation on it.
camelbeck (Mon, 03 Apr 2017 08:01:25 GMT):
https://github.com/pytest-dev/pytest-cov/blob/master/setup.py
camelbeck (Mon, 03 Apr 2017 08:01:56 GMT):
In pytest-cov project, it does depend on coverage package.
grapebaba (Mon, 03 Apr 2017 09:00:23 GMT):
:grinning:Thanks @camelbeck
grapebaba (Mon, 03 Apr 2017 09:00:49 GMT):
hope others review this patch ASAP
baohua (Wed, 05 Apr 2017 01:33:04 GMT):
@camelbeck after the ci verification passed, should post the patch url here to encourage more reviews.
camelbeck (Wed, 05 Apr 2017 04:11:12 GMT):
@baohua thanks for reminding me. https://gerrit.hyperledger.org/r/#/c/7637/ here is the link for my patch, welcome for review.
camelbeck (Wed, 05 Apr 2017 04:11:52 GMT):
And everyone can find some information for this item. https://jira.hyperledger.org/browse/FAB-2938
baohua (Wed, 05 Apr 2017 05:25:28 GMT):

Item #1: Jira board status (chang will sync).
baohua (Fri, 07 Apr 2017 03:01:17 GMT):
chang, pls help share the task status
lafenicecc (Fri, 07 Apr 2017 03:01:39 GMT):
coverage test is done, good job @camelbeck
lafenicecc (Fri, 07 Apr 2017 03:02:06 GMT):
what about e2e test? :grin: @ray
baohua (Fri, 07 Apr 2017 03:03:50 GMT):
aha, we have that item later. u wanna sync now or later? @ray
ray (Fri, 07 Apr 2017 03:04:45 GMT):
@WeiHu and me have built a basic framework of the e2e test of our sdk-py (with the help of node sdk and java sdk) and we are working together on my personal github repo, we plan to re-structure the patch-set after a certain period and submit a CR to upstream
baohua (Fri, 07 Apr 2017 03:05:01 GMT):
great! ray and wei
baohua (Fri, 07 Apr 2017 03:05:21 GMT):
while i would suggest we first submit some basic code framework for review.
baohua (Fri, 07 Apr 2017 03:05:35 GMT):
This is also for the item #2: https://gerrit.hyperledger.org/r/#/q/project:fabric-sdk-py
baohua (Fri, 07 Apr 2017 03:05:45 GMT):
We encourage each patchset keep smaller and focused.
ray (Fri, 07 Apr 2017 03:05:55 GMT):
https://github.com/oldsharp/fabric-sdk-py/tree/fab-2871 that's the branch we are now working on
baohua (Fri, 07 Apr 2017 03:06:16 GMT):
let's move quickly with smaller steps, rather than throw out bunch of code one time~~
baohua (Fri, 07 Apr 2017 03:06:37 GMT):
close collaboration will be more efficient, how do u think?
ray (Fri, 07 Apr 2017 03:07:31 GMT):
Yes, I mean submit several refined CRs to upstream, not a bunch of code ;-)
lafenicecc (Fri, 07 Apr 2017 03:07:56 GMT):
:heart_eyes:
baohua (Fri, 07 Apr 2017 03:08:01 GMT):
thanks! ray, look forward to seeing ur patchsets soon!
baohua (Fri, 07 Apr 2017 03:08:51 GMT):
OK, everyone pls help review each new patchset, and after submitting a patchset, remember to share within the channel after ci passed to call for reviewers. Thanks!
baohua (Fri, 07 Apr 2017 03:09:06 GMT):
OK. item#3. MVP remaining tasks discussion (kai will sync, 1768 to @lafenicecc and 1769 to @grapebaba).
baohua (Fri, 07 Apr 2017 03:09:20 GMT):
@grapebaba could u help sync the mvp work?
baohua (Fri, 07 Apr 2017 03:09:30 GMT):
@lafenicecc for comments, too
grapebaba (Fri, 07 Apr 2017 03:09:51 GMT):
i am still doing 1769
ray (Fri, 07 Apr 2017 03:10:10 GMT):
Let's move quickly :-)
grapebaba (Fri, 07 Apr 2017 03:10:25 GMT):
since there are some differences between java and node sdk
ray (Fri, 07 Apr 2017 03:11:04 GMT):
seem the network delay of my side is terrible :-(
grapebaba (Fri, 07 Apr 2017 03:11:19 GMT):
I try to find a better way
baohua (Fri, 07 Apr 2017 03:11:31 GMT):
thanks kai.
baohua (Fri, 07 Apr 2017 03:11:41 GMT):
how about the 1768 @lafenicecc
lafenicecc (Fri, 07 Apr 2017 03:11:59 GMT):
i will collaborate more with :grapes:baba
grapebaba (Fri, 07 Apr 2017 03:12:07 GMT):
right now i feel the implementation of java SDK is more better than node
baohua (Fri, 07 Apr 2017 03:12:14 GMT):
sure, and each unfinished task can submit a WIP patchset for letting others know the work is beginning.
baohua (Fri, 07 Apr 2017 03:12:27 GMT):
aha, i know u're also a java expert!
camelbeck (Fri, 07 Apr 2017 03:12:39 GMT):

baohua (Fri, 07 Apr 2017 03:13:44 GMT):
:woo:
camelbeck (Fri, 07 Apr 2017 03:13:50 GMT):
OK, as @lafenicecc just mentioned, I finished coverage test this week, and satus on jira is marked DONE now.
baohua (Fri, 07 Apr 2017 03:14:26 GMT):
Thanks, chao, and have u go through the existing documentation and code structure already? :yin_yang:
camelbeck (Fri, 07 Apr 2017 03:15:14 GMT):
I have read the documents, but still have not read code now
baohua (Fri, 07 Apr 2017 03:15:26 GMT):
u must have setup the local env, right?
camelbeck (Fri, 07 Apr 2017 03:15:33 GMT):
yes
camelbeck (Fri, 07 Apr 2017 03:15:50 GMT):
with your docker images :grinning:
baohua (Fri, 07 Apr 2017 03:15:57 GMT):
the fabric code has recently changed a little. I hope u can help update our ci docker images to latest 0.8.8.
camelbeck (Fri, 07 Apr 2017 03:16:19 GMT):
Sure, no problem
baohua (Fri, 07 Apr 2017 03:16:26 GMT):
@lafenicecc pls help create a jira task for chao. :grimacing:
baohua (Fri, 07 Apr 2017 03:16:30 GMT):
thanks chao!
lafenicecc (Fri, 07 Apr 2017 03:16:30 GMT):

baohua (Fri, 07 Apr 2017 03:16:46 GMT):
OK. item #5: E2E test (Ray Chen will sync) has synced already.
baohua (Fri, 07 Apr 2017 03:17:02 GMT):
Do we have other issues to discuss today?
ray (Fri, 07 Apr 2017 03:17:07 GMT):
@camelbeck question about the coverage test tool you choose: I saw you choose a tool called py-cover ? instead of coverage, what's your consideration, can you share a little bit about this?
baohua (Fri, 07 Apr 2017 03:17:23 GMT):
good question.

camelbeck (Fri, 07 Apr 2017 03:18:01 GMT):
I have recorded the reason for this choice.
camelbeck (Fri, 07 Apr 2017 03:18:34 GMT):
Have you read about that? Or still have questions? @ray
lafenicecc (Fri, 07 Apr 2017 03:18:37 GMT):
very detailed description, cool!
camelbeck (Fri, 07 Apr 2017 03:19:15 GMT):
Simply speaking, pytest-cov can be integrated with pytest.
ray (Fri, 07 Apr 2017 03:19:29 GMT):
So we used a hybrid solution, do we?
camelbeck (Fri, 07 Apr 2017 03:20:03 GMT):
Coverage in my solution is only used to get the coverage test result.
camelbeck (Fri, 07 Apr 2017 03:20:20 GMT):
But, pytest-cov depends on coverage package.
ray (Fri, 07 Apr 2017 03:21:04 GMT):
Okay I see. Thanks for your detailed explanation @camelbeck :-)
baohua (Fri, 07 Apr 2017 03:21:20 GMT):
@camelbeck Have u solved the ci stuck problem finally?
baohua (Fri, 07 Apr 2017 03:21:52 GMT):
test/unit/keyvaluestore_test.py why would stuck there?
camelbeck (Fri, 07 Apr 2017 03:22:42 GMT):
Not yet, actually in my own environment, most of the time I run make unittest, the process will be stuck there.
baohua (Fri, 07 Apr 2017 03:22:56 GMT):
Let's record the stuck problem, and maybe can raise a separate bug in jira tasks.
baohua (Fri, 07 Apr 2017 03:23:41 GMT):
Ok, last time remember @grapebaba has proposed the rxpy discussion, Have u created the issue? any further progress on that?
baohua (Fri, 07 Apr 2017 03:23:55 GMT):
:train:
grapebaba (Fri, 07 Apr 2017 03:24:15 GMT):

camelbeck (Fri, 07 Apr 2017 03:25:57 GMT):
I think we could make some improvements to our Makefile.
camelbeck (Fri, 07 Apr 2017 03:26:05 GMT):
Just suggestions
baohua (Fri, 07 Apr 2017 03:26:22 GMT):
Sure @camelbeck feel free to create jira task and share here for discussion first.
baohua (Fri, 07 Apr 2017 03:26:37 GMT):
any suggestion would be encouraged in open-source world
camelbeck (Fri, 07 Apr 2017 03:26:51 GMT):
OK
baohua (Fri, 07 Apr 2017 03:26:54 GMT):
OK, any more issues?
camelbeck (Fri, 07 Apr 2017 03:26:59 GMT):

Does python sdk still not support Fabric v1.0?

It's totally for fabric now. The team is hard working to finish it soon, and welcome for help~

@baohua can you clarify please? are there some requirements that folks should be looking at? or is the SDK ready to go? tested, etc
baohua (Tue, 11 Apr 2017 02:28:37 GMT):
@markparz The sdk is still under-development to support fabric 1.0. hopefully to finish with the fabric 1.0 relase.

lafenicecc (Fri, 14 Apr 2017 03:02:08 GMT):
FAB-3032 (about update images to 0.8.8 version) can be marked done? @camelbeck
camelbeck (Fri, 14 Apr 2017 03:02:41 GMT):
No, I have done some investigation on it, but still not finished it.
lafenicecc (Fri, 14 Apr 2017 03:03:05 GMT):
A recent patch already did that :grin:
lafenicecc (Fri, 14 Apr 2017 03:03:17 GMT):
Now the ci is using 0.8.8
camelbeck (Fri, 14 Apr 2017 03:03:32 GMT):
Yes, I saw it
camelbeck (Fri, 14 Apr 2017 03:04:06 GMT):
So this item can be marked DONE?
lafenicecc (Fri, 14 Apr 2017 03:04:14 GMT):
I suppose so
camelbeck (Fri, 14 Apr 2017 03:04:34 GMT):

lafenicecc (Fri, 14 Apr 2017 03:06:56 GMT):
Work in Progress? to my understanding :)
baohua (Fri, 14 Apr 2017 03:07:28 GMT):

:sweat_smile:
ray (Fri, 14 Apr 2017 03:08:57 GMT):
I designed the module structure, but not ready for code review right now. Wei and me just synced and both were busy this week. I will try to make some progress this weekend
baohua (Fri, 14 Apr 2017 03:09:18 GMT):
thanks, ray! that's nice usage of the gerrit tool

lafenicecc (Fri, 14 Apr 2017 03:14:46 GMT):
Sure
lafenicecc (Fri, 14 Apr 2017 03:15:21 GMT):
waiting for grapebaba's new patch.. RxPy does have a learning curve for me..
baohua (Fri, 14 Apr 2017 03:15:35 GMT):
yeap, let's keep close collaboration, and make the mvp done soon. fabric 1.0's features will be frozen this month. so there will be no big change later.
grapebaba (Fri, 14 Apr 2017 03:16:20 GMT):
Rxpy have little document, and I suggest we can refer to RxJS
lafenicecc (Fri, 14 Apr 2017 03:16:32 GMT):
Thanks
baohua (Fri, 14 Apr 2017 03:16:35 GMT):
thanks! and then we can have the e2e test done @ray , before the announcement of supporting fabric 1.0 :)
baohua (Fri, 14 Apr 2017 03:16:50 GMT):
OK, item #4: Test coverage functionality enhancement (Chao Li will sync)
baohua (Fri, 14 Apr 2017 03:16:56 GMT):

baohua (Fri, 14 Apr 2017 03:17:06 GMT):
@camelbeck have u met the problem?
camelbeck (Fri, 14 Apr 2017 03:17:18 GMT):
Actually not
camelbeck (Fri, 14 Apr 2017 03:17:32 GMT):
I will try to find the reason for this issue ASAP.
baohua (Fri, 14 Apr 2017 03:17:33 GMT):

lafenicecc (Fri, 14 Apr 2017 03:17:40 GMT):
I met that problem too
camelbeck (Fri, 14 Apr 2017 03:17:40 GMT):
2.7
baohua (Fri, 14 Apr 2017 03:17:47 GMT):
strange, as the ci does not complain
grapebaba (Fri, 14 Apr 2017 03:17:54 GMT):
make clean
baohua (Fri, 14 Apr 2017 03:17:57 GMT):
it should be ok for py 2.7
baohua (Fri, 14 Apr 2017 03:18:06 GMT):
yeap, make clean before the test
camelbeck (Fri, 14 Apr 2017 03:18:16 GMT):
@grapebaba I will have another try later
baohua (Fri, 14 Apr 2017 03:18:31 GMT):
pls help track this issue @lafenicecc maybe u can create a bug in jira and assign to chao
grapebaba (Fri, 14 Apr 2017 03:18:32 GMT):
after make clean
lafenicecc (Fri, 14 Apr 2017 03:18:39 GMT):
OK!
grapebaba (Fri, 14 Apr 2017 03:18:42 GMT):
i don't have problem now
camelbeck (Fri, 14 Apr 2017 03:19:03 GMT):

camelbeck (Fri, 14 Apr 2017 03:21:44 GMT):
OK, I will do some further investigation for this issue.
ray (Fri, 14 Apr 2017 03:22:22 GMT):
@bauhua no extra info
baohua (Fri, 14 Apr 2017 03:22:44 GMT):
OK
baohua (Fri, 14 Apr 2017 03:22:55 GMT):
that's the main agenda, so any more issues to discuss today?
lafenicecc (Fri, 14 Apr 2017 03:23:16 GMT):
Sorry I missed something in the jira board. I notice Jim Zhang created a issue for all sdk projects
lafenicecc (Fri, 14 Apr 2017 03:23:30 GMT):
FAB-3081, might be a reminding: Remove /api/v1/cfssl prefix on fabric-ca-server endpoints

https://jira.hyperledger.org/browse/FAB-3081
lafenicecc (Fri, 14 Apr 2017 03:24:15 GMT):
Please notice this
baohua (Fri, 14 Apr 2017 03:24:20 GMT):
aha, big change!
baohua (Fri, 14 Apr 2017 03:24:43 GMT):
that maybe why install fails sometime, thanks for pointing-out @lafenicecc
baohua (Fri, 14 Apr 2017 03:24:43 GMT):
that may be why install fails sometime, thanks for pointing-out @lafenicecc
lafenicecc (Fri, 14 Apr 2017 03:24:47 GMT):
For example, change /api/v1/cfssl/enroll to /enroll. This is true for all REST URLs to fabric-ca-server. Support for the /api/v1/cfssl prefixed routes will be removed soon.
baohua (Fri, 14 Apr 2017 03:25:48 GMT):
pls also notice this @grapebaba may change soon
baohua (Fri, 14 Apr 2017 03:25:58 GMT):
OK, any more issues?
grapebaba (Fri, 14 Apr 2017 03:26:06 GMT):
ok
baohua (Fri, 14 Apr 2017 03:26:41 GMT):
OK, if there's no more topics, will end the meeting.

baohua (Sun, 23 Apr 2017 01:27:39 GMT):
i create a jira task on changing with the new fabirc-ca restful API, who would volunteer to fix this? it should be simple enough, https://jira.hyperledger.org/browse/FAB-3345

baohua (Mon, 24 Apr 2017 01:57:20 GMT):
@camelbeck i notice everytime we run coverage, there will generate some .coverage...xxx files under test/. could u help update the makefile to let make clean also remove those files?
baohua (Mon, 24 Apr 2017 01:57:31 GMT):
feel free to create a jira task before take on hand :)
david_dornseifer (Mon, 24 Apr 2017 02:11:55 GMT):
@baohua executing the tests just in the py35 environment `tox -e py35` breaks with the same error as well if python3.5.0 is the interpreter. The problem also seems to occur if Python3.4 (https://github.com/docker/compose/issues/4729).

#item 1: chang pls help sync the jira task status
lafenicecc (Fri, 28 Apr 2017 03:01:17 GMT):
There are 3 tasks in progress
lafenicecc (Fri, 28 Apr 2017 03:02:02 GMT):
1) FAB-1769 send_transaction. @grapebaba has made great progress this week, and still some works ahead. He can sync later.
lafenicecc (Fri, 28 Apr 2017 03:02:33 GMT):
2) FAB-2871 implement e2e test, which @ray is working on. He will sync too
lafenicecc (Fri, 28 Apr 2017 03:03:00 GMT):
3) FAB-3437 update with latest protofiles. @baohua is working on that, keeping with fabric changes.

@grapebaba @ray hope goes well?
grapebaba (Fri, 28 Apr 2017 03:03:44 GMT):
yeah, 1769 done
baohua (Fri, 28 Apr 2017 03:04:12 GMT):
the fabric code changes the configtx.yaml structure recently, so i need to update the 3437 later with new compose environment.
grapebaba (Fri, 28 Apr 2017 03:04:16 GMT):
that means we finish all external invocation including CA, PEER, ORDERER
ray (Fri, 28 Apr 2017 03:04:30 GMT):
About fab-2871:
My side: Heavily involved with company's project, very few free time available until May 15.
Wei Hu: Still no progress.
Should we re-assign the e2e task? Or is this ok to wait for some more time?
baohua (Fri, 28 Apr 2017 03:04:58 GMT):
ok, who will volunteer to help the e2e framework design?
grapebaba (Fri, 28 Apr 2017 03:05:05 GMT):
but i made a mistake which install test should no need sending to orderer
camelbeck (Fri, 28 Apr 2017 03:05:48 GMT):
I'm still not very familiar with e2e so far, but I think I can have a try for fab-2871.
baohua (Fri, 28 Apr 2017 03:06:00 GMT):
aha, kai, pls help fix that ASAP.. maybe a new jira task first.
baohua (Fri, 28 Apr 2017 03:06:05 GMT):
Thanks @camelbeck
camelbeck (Fri, 28 Apr 2017 03:06:26 GMT):
:grin:
baohua (Fri, 28 Apr 2017 03:06:37 GMT):
First, you may create some simple high-level worksteps, with leaving the api implemented later
baohua (Fri, 28 Apr 2017 03:07:03 GMT):
e.g., a typical scenario: user use the sdk, to access the network, to deploy/invoke chaincode
baohua (Fri, 28 Apr 2017 03:07:16 GMT):
we need several typical scenarios first to show how people may use the sdk.
baohua (Fri, 28 Apr 2017 03:07:31 GMT):
certainly u can refer the java/node sdk's scenarios examples.
camelbeck (Fri, 28 Apr 2017 03:07:37 GMT):
OK, I think it is a great chance for me to get familiar with SDK and fabric, too.
baohua (Fri, 28 Apr 2017 03:07:53 GMT):
Yeap, very good starting-point.
baohua (Fri, 28 Apr 2017 03:08:22 GMT):
@grapebaba pls help fix the install problem, and we will fill with fuel to run! :airplane_arriving:
baohua (Fri, 28 Apr 2017 03:08:41 GMT):
OK, item #2： Patchset for review.
baohua (Fri, 28 Apr 2017 03:08:48 GMT):
https://gerrit.hyperledger.org/r/#/q/project:fabric-sdk-py
baohua (Fri, 28 Apr 2017 03:09:04 GMT):
Each patchset need a jira task number, and pls add the patchset url to the jira task's comments.
baohua (Fri, 28 Apr 2017 03:09:25 GMT):
Also, after ci passed, pls post the patchset url to the channel for call-for-review.
camelbeck (Fri, 28 Apr 2017 03:09:41 GMT):
:ok_hand:
baohua (Fri, 28 Apr 2017 03:10:12 GMT):
@lafenicecc pls talk to david about the 8521
lafenicecc (Fri, 28 Apr 2017 03:10:24 GMT):
Ok i will
baohua (Fri, 28 Apr 2017 03:10:26 GMT):
thanks
baohua (Fri, 28 Apr 2017 03:10:47 GMT):
item #3: MVP remaining tasks discussion (1769 done by @grapebaba).
baohua (Fri, 28 Apr 2017 03:10:51 GMT):
great progress
baohua (Fri, 28 Apr 2017 03:11:07 GMT):
@grapebaba pls help create jira tasks for the remaining steps we need to do.
grapebaba (Fri, 28 Apr 2017 03:11:18 GMT):
ok
baohua (Fri, 28 Apr 2017 03:11:20 GMT):
would suggest each task as simple as possible, then people will be easy to pick
lafenicecc (Fri, 28 Apr 2017 03:11:29 GMT):
agreed
baohua (Fri, 28 Apr 2017 03:11:33 GMT):
we need run fast with smaller steps, thanks!
grapebaba (Fri, 28 Apr 2017 03:11:50 GMT):
now we can start implement all the interfaces in the SDK
baohua (Fri, 28 Apr 2017 03:11:57 GMT):
OK. ray has already synced item #4: e2e tests.
baohua (Fri, 28 Apr 2017 03:12:19 GMT):
@grapebaba I would suggest we define those apis first, then ask team to help implement.
baohua (Fri, 28 Apr 2017 03:12:30 GMT):
API definition is quite important
baohua (Fri, 28 Apr 2017 03:12:54 GMT):
there're already some apis, everyone pls help refine/review and implement. thanks!
grapebaba (Fri, 28 Apr 2017 03:12:56 GMT):
ok
ray (Fri, 28 Apr 2017 03:13:11 GMT):
ok
baohua (Fri, 28 Apr 2017 03:13:33 GMT):
Ok, that's the main agenda, any more issue to discuss?
camelbeck (Fri, 28 Apr 2017 03:14:03 GMT):
@baohua, for the .coverage.*** files issue.
baohua (Fri, 28 Apr 2017 03:14:11 GMT):
yeap
camelbeck (Fri, 28 Apr 2017 03:14:20 GMT):
Actually I have not recreated the issue. I do notice many .coverage.*** files under the fabric-sdk-py directory (not the test/ you pointed out) will be generated during the test process, but they all are temporary and will be deleted if testing is successful. And they will remain there if testing fails.
baohua (Fri, 28 Apr 2017 03:14:51 GMT):
yes, so i would suggest we add those files in the `make clean` script.
baohua (Fri, 28 Apr 2017 03:14:59 GMT):
in case they remain in the dir.
camelbeck (Fri, 28 Apr 2017 03:15:24 GMT):
yes, that's one way to solve it.
baohua (Fri, 28 Apr 2017 03:15:28 GMT):
you can see the `find ...` cmd in the makefile's clean section.
baohua (Fri, 28 Apr 2017 03:15:47 GMT):
certainly will like to hear ur advice on handle that
baohua (Fri, 28 Apr 2017 03:16:18 GMT):
@lafenicecc pls help create a jira task first on the issue.
baohua (Fri, 28 Apr 2017 03:16:40 GMT):
@camelbeck pls help design a clever solution :grinning:
lafenicecc (Fri, 28 Apr 2017 03:16:43 GMT):
ok
camelbeck (Fri, 28 Apr 2017 03:16:47 GMT):
OK, I will update with the information under that task.
baohua (Fri, 28 Apr 2017 03:16:59 GMT):
Thanks
camelbeck (Fri, 28 Apr 2017 03:17:07 GMT):
:grinning:

https://gerrit.hyperledger.org/r/#/c/9215/ welcome for review
baohua (Thu, 11 May 2017 01:14:28 GMT):
thanks and @camelbeck pls help review 9201, changed the unittest by @david_dornseifer
camelbeck (Thu, 11 May 2017 01:29:45 GMT):
Sure
baohua (Thu, 11 May 2017 02:06:27 GMT):
ci fails...
grapebaba (Thu, 11 May 2017 02:11:11 GMT):
@david_dornseifer please kindly skip chaincode test in your patch, that is a new feature we need follow but not related CA
camelbeck (Thu, 11 May 2017 02:42:51 GMT):
@baohua I notice the failure of 9201 is because of the conflict to my new patch. How to deal with it in this situation? Need I revoke or modify the patch first?
baohua (Thu, 11 May 2017 02:43:45 GMT):
aha, both are not merged yet, hence would suggest u talked with david to make agreement.
baohua (Thu, 11 May 2017 02:44:12 GMT):
if ur patchset is merged already, then the new one need do a rebase on the master branch.
camelbeck (Thu, 11 May 2017 02:45:24 GMT):
OK. You cannot merge the patch that fails in CI, right?
baohua (Thu, 11 May 2017 02:45:48 GMT):
we should fix the problem before do the merge action :)
camelbeck (Thu, 11 May 2017 02:46:09 GMT):
OK, got it, thanks, :grinning:
baohua (Thu, 11 May 2017 02:47:19 GMT):

baohua (Thu, 11 May 2017 08:15:39 GMT):
haha, python is quite easy to learn, i guess, more like native human language sometimes. And I also like lanaguages like javascript/go.... too
zerppen (Thu, 11 May 2017 08:34:26 GMT):

u know how to check the error msg, right?
camelbeck (Fri, 12 May 2017 03:10:24 GMT):
Yes, it may because the conflict with david's 3788.

https://gerrit.hyperledger.org/r/#/c/9201/ this one
baohua (Fri, 12 May 2017 03:11:14 GMT):
The patchset only runs on the latest master branch
baohua (Fri, 12 May 2017 03:11:27 GMT):
so non-merged one cannot affect ur new patchset :)
camelbeck (Fri, 12 May 2017 03:11:50 GMT):
OK, so I need to check the error message further.
baohua (Fri, 12 May 2017 03:12:03 GMT):
aha, and remember to do rebase often. see git doc a little.
baohua (Fri, 12 May 2017 03:12:04 GMT):

OK. any update from @lafenicecc ?
baohua (Fri, 12 May 2017 03:13:41 GMT):
i guess we need to fix the chaincode install problem soon
grapebaba (Fri, 12 May 2017 03:13:45 GMT):
i wonder who is interested in these tasks
baohua (Fri, 12 May 2017 03:13:51 GMT):
i will take a look
grapebaba (Fri, 12 May 2017 03:14:03 GMT):
such as instantiate and invoke
baohua (Fri, 12 May 2017 03:14:25 GMT):
sure, we welcome people joining to contribute
baohua (Fri, 12 May 2017 03:14:45 GMT):
sunlight is ahead!
lafenicecc (Fri, 12 May 2017 03:15:00 GMT):
can u give us a status summarize for now? so more volunteers would come out
baohua (Fri, 12 May 2017 03:15:10 GMT):
after we fix install, and then instantiate/invoke should be easy to do.
lafenicecc (Fri, 12 May 2017 03:15:24 GMT):
i suppose some people don't know where to start with
baohua (Fri, 12 May 2017 03:15:29 GMT):
then the mvp would work!
baohua (Fri, 12 May 2017 03:15:34 GMT):
aha, good question
baohua (Fri, 12 May 2017 03:16:04 GMT):
We hope to mitigate the issue by jira board task and the online discussions.
baohua (Fri, 12 May 2017 03:16:15 GMT):
Any question, just ask
baohua (Fri, 12 May 2017 03:16:31 GMT):
and we may need more documentation in details?
WeiHu (Fri, 12 May 2017 03:16:36 GMT):
@grapebaba I'm interested, but I need some time to get familiar with fabric and py-sdk..
baohua (Fri, 12 May 2017 03:16:53 GMT):

baohua (Fri, 12 May 2017 03:18:10 GMT):
@WeiHu feel free to ask any question, the community is warm and friendly to everyone :)
baohua (Fri, 12 May 2017 03:18:19 GMT):
OK
grapebaba (Fri, 12 May 2017 03:18:30 GMT):
i assume we here should know the basic data flow in fabric
lafenicecc (Fri, 12 May 2017 03:19:01 GMT):
now the install test has a "TODO: create channel not implement yet"
baohua (Fri, 12 May 2017 03:19:05 GMT):
Currently, i strongly recommend everyone have a look at fabric/examples/e2e_cli
SeeGo (Fri, 12 May 2017 03:19:29 GMT):
ok
lafenicecc (Fri, 12 May 2017 03:19:34 GMT):
is this necessrary for the mvp?
baohua (Fri, 12 May 2017 03:19:58 GMT):
to support working on new channel, we need the create channel func
grapebaba (Fri, 12 May 2017 03:20:11 GMT):
yes, create channel is not implemented so that we use default channel now
WeiHu (Fri, 12 May 2017 03:20:22 GMT):
:grin:
baohua (Fri, 12 May 2017 03:20:42 GMT):
yeap, and using default channel, we can only use the admin to operate, pls notice
baohua (Fri, 12 May 2017 03:21:24 GMT):
the chaincode test case now is using common user role from fabric-ca, need to revise it
baohua (Fri, 12 May 2017 03:21:39 GMT):
who wanna help fix this?
lafenicecc (Fri, 12 May 2017 03:21:47 GMT):
the Channel class and functions are not implemented in python sdk yet, right?
baohua (Fri, 12 May 2017 03:21:56 GMT):
should not difficult, i guess
lafenicecc (Fri, 12 May 2017 03:22:28 GMT):
need to catch up other sdks :grin:
baohua (Fri, 12 May 2017 03:22:41 GMT):
@WeiHu do u wanna help revise the user role?
grapebaba (Fri, 12 May 2017 03:23:04 GMT):
https://jira.hyperledger.org/browse/FAB-3483?filter=-2
WeiHu (Fri, 12 May 2017 03:23:30 GMT):
I can have a try
grapebaba (Fri, 12 May 2017 03:23:35 GMT):
@lafenicecc we have a discussion about channel and chain
grapebaba (Fri, 12 May 2017 03:23:54 GMT):
actually we use Chain class represent channel now
baohua (Fri, 12 May 2017 03:24:29 GMT):
thanks wei
lafenicecc (Fri, 12 May 2017 03:24:30 GMT):
ok i got it
baohua (Fri, 12 May 2017 03:24:34 GMT):
@grapebaba i agree
baohua (Fri, 12 May 2017 03:24:46 GMT):
we can first use chain--channel mapping first
baohua (Fri, 12 May 2017 03:25:11 GMT):
But i also suggest we use the name of channel class
baohua (Fri, 12 May 2017 03:25:19 GMT):
how do u think?
grapebaba (Fri, 12 May 2017 03:25:34 GMT):
ok
baohua (Fri, 12 May 2017 03:26:04 GMT):
thanks, let's create/update tasks on jira
lafenicecc (Fri, 12 May 2017 03:26:24 GMT):
which one do you think we should learn from, sdk-node or sdk-java? @grapebaba
grapebaba (Fri, 12 May 2017 03:26:28 GMT):
sure
grapebaba (Fri, 12 May 2017 03:26:51 GMT):
better both:sweat_smile:
baohua (Fri, 12 May 2017 03:27:03 GMT):
java is more like py from structure
lafenicecc (Fri, 12 May 2017 03:27:03 GMT):
alright haha
grapebaba (Fri, 12 May 2017 03:27:25 GMT):
java first
baohua (Fri, 12 May 2017 03:27:29 GMT):
OK. Item #4: E2E work, i guess @camelbeck is working on it.
camelbeck (Fri, 12 May 2017 03:27:45 GMT):
Yes, I have read node’s e2e process, and now get the basic idea on what we should do. Next, I will update on jira of the architecture design.
baohua (Fri, 12 May 2017 03:27:54 GMT):
thanks!
baohua (Fri, 12 May 2017 03:28:07 GMT):
:hibiscus:
camelbeck (Fri, 12 May 2017 03:28:16 GMT):
BTW, I would like introduce one new member to our project.

camelbeck (Fri, 12 May 2017 03:28:28 GMT):

lafenicecc (Fri, 12 May 2017 03:28:39 GMT):

baohua (Fri, 12 May 2017 03:28:44 GMT):

camelbeck (Fri, 12 May 2017 03:29:03 GMT):
OK
camelbeck (Fri, 12 May 2017 03:29:12 GMT):
I will ask him have a try later
lafenicecc (Fri, 12 May 2017 03:29:18 GMT):
is this bug in rocketchat or config issue..
baohua (Fri, 12 May 2017 03:29:29 GMT):
no, the channel is open to everyone, but sometime, people cannot search it out... @toddb
toddb (Fri, 12 May 2017 03:29:29 GMT):
Has joined the channel.
baohua (Fri, 12 May 2017 03:30:05 GMT):
guess a bug, good news is there's a rocketchat upgrade recently
camelbeck (Fri, 12 May 2017 03:30:19 GMT):
I will invite him to our wechat group later, too.
ray (Fri, 12 May 2017 03:30:26 GMT):
you mean server end upgrade ?
baohua (Fri, 12 May 2017 03:30:31 GMT):

camelbeck (Fri, 12 May 2017 03:31:04 GMT):
He will begin with working on the e2e task together with me.
baohua (Fri, 12 May 2017 03:31:15 GMT):
OK, very efficient discussions today. more issues?
camelbeck (Fri, 12 May 2017 03:32:02 GMT):
Not any more for me
baohua (Fri, 12 May 2017 03:32:17 GMT):
finally, we will have the 1chain---m channel model, i guess @grapebaba
grapebaba (Fri, 12 May 2017 03:32:42 GMT):
correct
baohua (Fri, 12 May 2017 03:33:03 GMT):
OK any more issue for today?
baohua (Fri, 12 May 2017 03:33:34 GMT):

https://gerrit.hyperledger.org/r/#/c/8019/
I see @baohua 's +1 on this, should I abandon this patch or just let @camelbeck continue work on top of it?
camelbeck (Fri, 12 May 2017 06:03:02 GMT):
I am now working on this patch, and will remove the failure soon.
ray (Fri, 12 May 2017 06:04:59 GMT):
@camelbeck it's on your call. Feel free to create a new CR or push your commit to this ref (8019) if you want to reuse this one.
camelbeck (Fri, 12 May 2017 06:09:24 GMT):
Sorry, I didn't express clearly. I meant I am working on my failed patch https://gerrit.hyperledger.org/r/#/c/9215/, :grimacing: But we will continue the e2e work based on your patch. Thank you.

WeiHu (Fri, 02 Jun 2017 03:02:18 GMT):
:raised_hand:
grapebaba (Fri, 02 Jun 2017 03:02:53 GMT):
AFAIK, no update for mvp progress this week
baohua (Fri, 02 Jun 2017 03:03:22 GMT):
ok, so next step i guess we should support the install operation, right?
baohua (Fri, 02 Jun 2017 03:04:14 GMT):
i suppose someone's working on this since last week meeting?
grapebaba (Fri, 02 Jun 2017 03:04:27 GMT):
I thought it should be create channel
baohua (Fri, 02 Jun 2017 03:04:44 GMT):
create channel, aha
baohua (Fri, 02 Jun 2017 03:04:50 GMT):
search the jira, not finding this issue?
baohua (Fri, 02 Jun 2017 03:05:14 GMT):
difficult to use for jira...
baohua (Fri, 02 Jun 2017 03:06:01 GMT):
i guess there's no issues, kai, pls help create the issue for channel create, thanks!
grapebaba (Fri, 02 Jun 2017 03:06:31 GMT):
https://jira.hyperledger.org/browse/FAB-3483
grapebaba (Fri, 02 Jun 2017 03:06:33 GMT):
this one
grapebaba (Fri, 02 Jun 2017 03:06:55 GMT):
refactor chain to channel
grapebaba (Fri, 02 Jun 2017 03:07:03 GMT):
remember we discussed
baohua (Fri, 02 Jun 2017 03:07:07 GMT):
thanks, but this is just a refactor issue, we may need some explicit one like create channel
baohua (Fri, 02 Jun 2017 03:07:47 GMT):
would u help do the refactor part first?
grapebaba (Fri, 02 Jun 2017 03:08:22 GMT):
sure
baohua (Fri, 02 Jun 2017 03:08:44 GMT):
great, thanks!
baohua (Fri, 02 Jun 2017 03:09:06 GMT):
And anyone else wanna pick the channel create issue to finish? @tonyyang132 @WeiHu
baohua (Fri, 02 Jun 2017 03:09:25 GMT):
this needs collaboration with kai's work certainly
baohua (Fri, 02 Jun 2017 03:11:31 GMT):
aha, i notice wei is working on use role update
baohua (Fri, 02 Jun 2017 03:11:44 GMT):
so maybe tony can help @tonyyang132
tonyyang132 (Fri, 02 Jun 2017 03:12:28 GMT):
Umm... Still trying to pick things up, I'm not sure I understand the whole context, maybe I start off with something easier?
baohua (Fri, 02 Jun 2017 03:12:52 GMT):
sure, tony, would suggest u look at the doc first.
baohua (Fri, 02 Jun 2017 03:13:20 GMT):
Ok, i will add a todo for me :) TODO: baohua create the jira issue and work with kai to finish the channel creation func.
baohua (Fri, 02 Jun 2017 03:13:25 GMT):
OK, next item
tonyyang132 (Fri, 02 Jun 2017 03:13:29 GMT):

baohua (Fri, 02 Jun 2017 03:14:11 GMT):
how's that going?
WeiHu (Fri, 02 Jun 2017 03:15:02 GMT):
sorry i'm busy recently. i'm working on it, i have some idea, and it will be done after the 'create channel' task being done
baohua (Fri, 02 Jun 2017 03:15:44 GMT):
sure, pls no hesitate to post ur thoughts in jira or the channel for more discussions.
baohua (Fri, 02 Jun 2017 03:16:11 GMT):
we need agile collaboration with quick movements :)
baohua (Fri, 02 Jun 2017 03:16:30 GMT):
OK. and one patchset needs everyone's attention: https://gerrit.hyperledger.org/r/#/c/9887/
baohua (Fri, 02 Jun 2017 03:16:48 GMT):
This patchset disable/remove the testchainid for default channel
baohua (Fri, 02 Jun 2017 03:17:06 GMT):
Since then, we need the new app channel creation before everything @grapebaba
baohua (Fri, 02 Jun 2017 03:17:17 GMT):
that's why the channel creation is very important
grapebaba (Fri, 02 Jun 2017 03:17:22 GMT):
yeah
baohua (Fri, 02 Jun 2017 03:17:31 GMT):
btw, i would like to discuss the channel vs chain here
baohua (Fri, 02 Jun 2017 03:18:00 GMT):
channel is a network layer concept simply means a separate topic from kafka.
baohua (Fri, 02 Jun 2017 03:18:28 GMT):
chain is more complex, it contains the binding channel, and also other structures like ledger, will u guys agree?
baohua (Fri, 02 Jun 2017 03:19:04 GMT):
@grapebaba hence we cannot simply rename the chain-->channel, i guess
grapebaba (Fri, 02 Jun 2017 03:20:37 GMT):
ok, fair enough
baohua (Fri, 02 Jun 2017 03:21:11 GMT):
yeap, hence we will finally have the chain and channel roles together, while from the sdk side, it may use both
grapebaba (Fri, 02 Jun 2017 03:21:16 GMT):
we finally will have two class chain and channel, and separate the methods to them
baohua (Fri, 02 Jun 2017 03:21:25 GMT):
exactly!
baohua (Fri, 02 Jun 2017 03:21:36 GMT):
@WeiHu @tonyyang132 how do u guys think?
tonyyang132 (Fri, 02 Jun 2017 03:22:14 GMT):
yeah it'd make more sense
baohua (Fri, 02 Jun 2017 03:22:24 GMT):
thanks!
baohua (Fri, 02 Jun 2017 03:22:40 GMT):
Ok, no much other issues today, any more topics to discuss?
baohua (Fri, 02 Jun 2017 03:22:40 GMT):
Ok, no much other issues today from my side, any more topics to discuss?
grapebaba (Fri, 02 Jun 2017 03:23:18 GMT):
no for me
baohua (Fri, 02 Jun 2017 03:23:34 GMT):
tony or wei?
tonyyang132 (Fri, 02 Jun 2017 03:23:47 GMT):
nothing from my side either
baohua (Fri, 02 Jun 2017 03:24:06 GMT):

hi what's the difference between user and client in python sdk?
baohua (Sun, 04 Jun 2017 09:20:02 GMT):
client: a client role in the fabric network; user: a user is a permission role.
lujiang (Mon, 05 Jun 2017 10:48:18 GMT):
Hi, is there document or sample for how to use py Sdk? I did not find docker-compose.yaml in project, please guide
baohua (Tue, 06 Jun 2017 01:28:28 GMT):
@lujiang would like to suggest u have a look at the test cases, which shows examples on some usage cases. However, we do need some more formal usage documentation later. Would be glad if you can help write some, and @WeiHu is also working on e2e testing, which is related to usage, too
lujiang (Tue, 06 Jun 2017 01:33:53 GMT):
@baohua yes，I am glad to help with. Will take a look at the test case and @WeiHu is there some document for e2e testing which I can reference ?
baohua (Tue, 06 Jun 2017 01:35:17 GMT):
sure, thanks and feel free to ping the team if u have any question :)

qizhang (Tue, 06 Jun 2017 21:08:37 GMT):
I am also interested in the examples of using the fabric-sdk-python. @lujiang @baohua @WeiHu . There is a 'test' directory, but still not quite clear how to run the code there. Any advise would be appreciated.
baohua (Wed, 07 Jun 2017 01:44:32 GMT):
sure @qizhang, @lujiang and @WeiHu will help provide more usage cases. @grapebaba , doc is always important and not enough :)
grapebaba (Wed, 07 Jun 2017 01:45:44 GMT):
:sweat_smile:
lujiang (Wed, 07 Jun 2017 02:00:09 GMT):
fabric-sdk-node is good to reference, can we also provide an example like balance transfer?
baohua (Wed, 07 Jun 2017 02:42:43 GMT):
sure, like the idea!
WeiHu (Wed, 07 Jun 2017 02:56:50 GMT):

@baohua - in your opinion, what's the readiness of the python SDK for 1.0.0?
baohua (Mon, 12 Jun 2017 14:34:24 GMT):
hi, gari, the initial plan is to finish the first version(mvp) posting the release of fabric 1.0. Any suggestion from ur side?
baohua (Tue, 13 Jun 2017 02:09:18 GMT):
create a jira task on updating the proto files. anyone volunteer to fix that? https://jira.hyperledger.org/browse/FAB-4592.
baohua (Tue, 13 Jun 2017 02:09:26 GMT):
if no one pick it up today, i will fix it tmr :)
tonyyang132 (Tue, 13 Jun 2017 03:21:49 GMT):
@baohua guess I could take that
baohua (Tue, 13 Jun 2017 03:22:34 GMT):
thanks tony, could u help set urself as the assigner?
tonyyang132 (Tue, 13 Jun 2017 03:23:44 GMT):
done
baohua (Tue, 13 Jun 2017 03:23:59 GMT):
look forward to seeing the patchset, and feel free to add ur name in the contributor list at https://wiki.hyperledger.org/projects/fabric-sdk-py. thanks!
tonyyang132 (Tue, 13 Jun 2017 03:24:35 GMT):
OK:smile:
tonyyang132 (Tue, 13 Jun 2017 03:25:40 GMT):
I guess I could use a little bit more background too. Is there a relevant jira item about how and why these proto files are changed in fabric?
tonyyang132 (Tue, 13 Jun 2017 03:45:53 GMT):
@baohua can you shed some light ^^^ ?
baohua (Tue, 13 Jun 2017 03:46:49 GMT):
aha, if you wanna know, you have to find the patchset history for fabric...
baohua (Tue, 13 Jun 2017 03:47:20 GMT):
see: https://gerrit.hyperledger.org/r/#/q/project:fabric
tonyyang132 (Tue, 13 Jun 2017 03:57:28 GMT):
@baohua is this the one - https://gerrit.hyperledger.org/r/#/c/10495/ ?
tonyyang132 (Tue, 13 Jun 2017 03:57:43 GMT):
that's the latest that involves proto changes
baohua (Tue, 13 Jun 2017 03:58:15 GMT):
yes, and maybe some previous ones also change, as there're some time we missed the syncing with fabric code.
tonyyang132 (Tue, 13 Jun 2017 03:59:10 GMT):
doesn't seem to be the correct one... it only changes comments...
tonyyang132 (Tue, 13 Jun 2017 03:59:27 GMT):
can you point out which proto files that need syncing, or all of them?
tonyyang132 (Tue, 13 Jun 2017 04:01:54 GMT):
@baohua
baohua (Tue, 13 Jun 2017 04:02:28 GMT):
aha, you may use some diff tools to check the .proto files.
baohua (Tue, 13 Jun 2017 04:03:00 GMT):
the fabric ones are under protos/*
tonyyang132 (Tue, 13 Jun 2017 04:03:36 GMT):
OK, I'll do some research
baohua (Thu, 15 Jun 2017 02:39:46 GMT):

wangdong (Fri, 16 Jun 2017 03:06:13 GMT):
I have split the e2e test into part according to the node sdk. The first is to test the creating channel.
baohua (Fri, 16 Jun 2017 03:07:06 GMT):
any more comments?
wangdong (Fri, 16 Jun 2017 03:07:15 GMT):
but the creating channel is not realized in client
wangdong (Fri, 16 Jun 2017 03:07:18 GMT):
right?
baohua (Fri, 16 Jun 2017 03:07:40 GMT):
understand, dong, to avoid such kind of dependency, we would like to suggest create those apis first.
baohua (Fri, 16 Jun 2017 03:07:59 GMT):
to use direct return fake value to let the process pass first.
baohua (Fri, 16 Jun 2017 03:08:09 GMT):
then fill into each implement code, how do u think?
baohua (Fri, 16 Jun 2017 03:08:24 GMT):
also we can use the mock tools for that
wangdong (Fri, 16 Jun 2017 03:08:50 GMT):
fill into? You mean just leave this part as stub?
baohua (Fri, 16 Jun 2017 03:09:16 GMT):
e.g., we call some method, but we mock it out to just return the expected result
wangdong (Fri, 16 Jun 2017 03:09:29 GMT):
got it
baohua (Fri, 16 Jun 2017 03:09:32 GMT):
then after the method is implemented, it's easy to switch to it
wangdong (Fri, 16 Jun 2017 03:09:38 GMT):
OK
baohua (Fri, 16 Jun 2017 03:09:41 GMT):
thanks, hope we can get some progress next week :)
baohua (Fri, 16 Jun 2017 03:09:48 GMT):

one more thing the sdk spec is the most updated?
baohua (Fri, 16 Jun 2017 03:16:54 GMT):
no, the sdk spec is somehow out-of-dated
baohua (Fri, 16 Jun 2017 03:17:02 GMT):
but the main design process is till correct
wangdong (Fri, 16 Jun 2017 03:17:10 GMT):

thanks
baohua (Fri, 16 Jun 2017 03:17:21 GMT):

raheelz (Wed, 21 Jun 2017 22:59:30 GMT):
Hi all, I wanted to ask if the fabric-sdk-py is ready to be used with application. I would like to create an application using the fabric-sdk-py (similar to how marbles app is using the fabric-sdk-node ) Would there be any examples for using fabric-sdk-py? Thanks
baohua (Thu, 22 Jun 2017 01:36:45 GMT):
@raheelz not finished yet, but pls have a look at the `test` cases, where we have several supports, thanks for ur interest!
baohua (Thu, 22 Jun 2017 01:37:04 GMT):
@grapebaba where's ur patchset, sorry not finding it: https://gerrit.hyperledger.org/r/#/q/project:fabric-sdk-py+status:open
raheelz (Thu, 22 Jun 2017 02:14:24 GMT):
Thanks @baohua! I will take a look

Hi Team,
Congratulations for your successful participation in rolling Block chain Hyperledger. I am a newbie and thinking to be a contributor but not sure in which area I should try. I have installed Fabric component and do have inclination to deep dive into Fabric and Composer projects. I have tried these on Ubuntu – v16.04 (xenial) platform.
Can some pointer or task be shared initially so that I can try contributing in that specific area? I may be good in working or developing some USE CASE applications.
I do appreciate in participating in discussions so please do involve me. I am based in New Delhi, India.
baohua (Fri, 23 Jun 2017 02:58:41 GMT):
@srivmukk welcome, this is the python based sdk for fabric, if u love python, welcome to join!
baohua (Fri, 23 Jun 2017 02:58:50 GMT):
meeting will start at 2 mins
srivmukk (Fri, 23 Jun 2017 02:59:21 GMT):
Sure.. I will. Thanks
baohua (Fri, 23 Jun 2017 02:59:56 GMT):

:raised_back_of_hand:
WeiHu (Fri, 23 Jun 2017 03:03:39 GMT):
I wonder whether `create channel` is implemented?
baohua (Fri, 23 Jun 2017 03:04:10 GMT):
For sdk, it actually can assume the fabric network is already there (started, and peer already joined the new created channel).
WeiHu (Fri, 23 Jun 2017 03:04:13 GMT):
I'll finish fab-3885 after this task is done
baohua (Fri, 23 Jun 2017 03:04:39 GMT):
using the docker-compose files, after bootup, we can setup the channel and join through scripts first.
baohua (Fri, 23 Jun 2017 03:04:53 GMT):
How do u think, if this way works for u? wei
wangdong (Fri, 23 Jun 2017 03:05:18 GMT):
I am here
baohua (Fri, 23 Jun 2017 03:05:25 GMT):
@grapebaba i guess the chaincode operations have higher priority
WeiHu (Fri, 23 Jun 2017 03:05:55 GMT):
get it
baohua (Fri, 23 Jun 2017 03:06:03 GMT):
thanks, wei, pls do not stuck :)
baohua (Fri, 23 Jun 2017 03:06:22 GMT):
thanks @wangdong would u help update FAB-2871? the e2e api design?
baohua (Fri, 23 Jun 2017 03:06:49 GMT):
we just close ray's prior patchset, hope u can open new one for that
baohua (Fri, 23 Jun 2017 03:07:13 GMT):
https://jira.hyperledger.org/browse/FAB-2871
wangdong (Fri, 23 Jun 2017 03:07:44 GMT):
I just referred the node sdk. The first step will be creating channel test
wangdong (Fri, 23 Jun 2017 03:08:09 GMT):
I am trying to give birth it then
baohua (Fri, 23 Jun 2017 03:08:39 GMT):
yeap, dong, as suggested last week, we need the entire workflow defined first, then can implement each steps with other components being finished.
baohua (Fri, 23 Jun 2017 03:08:52 GMT):
thanks for the help!
baohua (Fri, 23 Jun 2017 03:09:14 GMT):
OK, and Proto Files Update: Tony Yang is working on FAB-4592
baohua (Fri, 23 Jun 2017 03:09:30 GMT):
the patchset is at https://gerrit.hyperledger.org/r/#/c/11003/
tonyyang132 (Fri, 23 Jun 2017 03:09:39 GMT):
Yeah
baohua (Fri, 23 Jun 2017 03:09:56 GMT):
Would highly encourage everyone to help review, not only just contributing code. review is very important :)
baohua (Fri, 23 Jun 2017 03:10:11 GMT):
any thing to sync, tony?
wangdong (Fri, 23 Jun 2017 03:10:16 GMT):
Ah, I will try to give a design then. Sorry for the miss.
baohua (Fri, 23 Jun 2017 03:10:31 GMT):
:snail:
tonyyang132 (Fri, 23 Jun 2017 03:10:50 GMT):
Nothing else other than asking help for reviews
tonyyang132 (Fri, 23 Jun 2017 03:10:57 GMT):
:grimacing:
baohua (Fri, 23 Jun 2017 03:11:07 GMT):
thanks, can would u like to share how do u update it? main steps?
srivmukk (Fri, 23 Jun 2017 03:11:07 GMT):
I can help in reviewing. Let me know please
qiang0723 (Fri, 23 Jun 2017 03:11:10 GMT):
I think i can help implement demo e2e @wangdong
baohua (Fri, 23 Jun 2017 03:11:12 GMT):
hence other people may learn :)
baohua (Fri, 23 Jun 2017 03:11:21 GMT):
@srivmukk feel free to review it!
wangdong (Fri, 23 Jun 2017 03:11:31 GMT):
@qiang0723 that will be greate
baohua (Fri, 23 Jun 2017 03:11:43 GMT):
every patchset is open, just add ur name there, then u're an honored review!
baohua (Fri, 23 Jun 2017 03:11:43 GMT):
every patchset is open, just add ur name there, then u're an honored reviewer!
tonyyang132 (Fri, 23 Jun 2017 03:12:29 GMT):
yeah. I diff'ed all the proto files with that of the fabric ones
tonyyang132 (Fri, 23 Jun 2017 03:13:48 GMT):
eliminated the ones that are only in fabric, and synced the rest, and then make proto
baohua (Fri, 23 Jun 2017 03:14:25 GMT):
yeap, thanks and remember to notice that some generated files needs a abstract import path
baohua (Fri, 23 Jun 2017 03:14:34 GMT):
due to limit support of pb
baohua (Fri, 23 Jun 2017 03:15:02 GMT):
and every code contributor, pls feel free to add ur name at the statistics at https://wiki.hyperledger.org/groups/twgc/team_di
baohua (Fri, 23 Jun 2017 03:15:21 GMT):
OK, EventHub: Chang Chen is working on FAB-4822
baohua (Fri, 23 Jun 2017 03:15:30 GMT):
https://jira.hyperledger.org/browse/FAB-4822
tonyyang132 (Fri, 23 Jun 2017 03:15:32 GMT):
sorry, how do you mean by abstract import path?
baohua (Fri, 23 Jun 2017 03:16:05 GMT):
@tonyyang132 u may notice we have manually update some import path in the generated py files.
lafenicecc (Fri, 23 Jun 2017 03:16:09 GMT):
Working on eventhub. Will have patchset next week
grapebaba (Fri, 23 Jun 2017 03:16:41 GMT):
@tonyyang132 we must change the import path of the proto files in fabric
tonyyang132 (Fri, 23 Jun 2017 03:16:58 GMT):
oops, I didn't manually update any generated py files
grapebaba (Fri, 23 Jun 2017 03:17:00 GMT):
please check the current py files header
tonyyang132 (Fri, 23 Jun 2017 03:17:08 GMT):
guess I need to take another look
grapebaba (Fri, 23 Jun 2017 03:17:10 GMT):
i don't mean py files
grapebaba (Fri, 23 Jun 2017 03:17:20 GMT):
i mean .proto files
tonyyang132 (Fri, 23 Jun 2017 03:17:26 GMT):
oh, proto files
tonyyang132 (Fri, 23 Jun 2017 03:17:40 GMT):
I did see those
grapebaba (Fri, 23 Jun 2017 03:17:46 GMT):
yeah
baohua (Fri, 23 Jun 2017 03:17:53 GMT):
like this one in ab.proto: `import "hfc/protos/common/common.proto";`
baohua (Fri, 23 Jun 2017 03:18:02 GMT):
the original one is `import common.proto`
baohua (Fri, 23 Jun 2017 03:18:16 GMT):
need to update the path as kai indicated
tonyyang132 (Fri, 23 Jun 2017 03:18:18 GMT):
prefixed by the hfc directory
baohua (Fri, 23 Jun 2017 03:18:41 GMT):
seems only several filed need that change @grapebaba ?
baohua (Fri, 23 Jun 2017 03:18:41 GMT):
seems only several files need that change @grapebaba ?
tonyyang132 (Fri, 23 Jun 2017 03:18:48 GMT):
I left those diffs as is
baohua (Fri, 23 Jun 2017 03:19:12 GMT):
yeap, that's smart action
baohua (Fri, 23 Jun 2017 03:19:52 GMT):
OK, for next item: we need some one to help add license headers to the source code: https://jira.hyperledger.org/browse/FAB-4742
baohua (Fri, 23 Jun 2017 03:20:03 GMT):
any volunteer?
baohua (Fri, 23 Jun 2017 03:20:30 GMT):
@srivmukk
srivmukk (Fri, 23 Jun 2017 03:20:36 GMT):
k
baohua (Fri, 23 Jun 2017 03:20:37 GMT):
would u like to help fix it?
grapebaba (Fri, 23 Jun 2017 03:20:39 GMT):
@tonyyang132 that is a workaround to generate correct py files
srivmukk (Fri, 23 Jun 2017 03:21:03 GMT):
@baohua .. Sure, I can try.
tonyyang132 (Fri, 23 Jun 2017 03:21:10 GMT):
Thanks @grapebaba for elaborating
baohua (Fri, 23 Jun 2017 03:21:21 GMT):
thanks, pls assign urself as the assignee in the jira link :)
grapebaba (Fri, 23 Jun 2017 03:21:26 GMT):
you must check the current project module and modify the .proto import
baohua (Fri, 23 Jun 2017 03:22:02 GMT):
mainly, we need an apache 2 header in every source code file, and some cc license description at the bottom of the documentation. feel free to fix one by one step.
baohua (Fri, 23 Jun 2017 03:22:21 GMT):
Ok, next item: Support provided password in the enroll request: FAB-3165
baohua (Fri, 23 Jun 2017 03:22:25 GMT):
https://jira.hyperledger.org/browse/FAB-3165
baohua (Fri, 23 Jun 2017 03:22:49 GMT):
this means when enroll, user can optionally choose to use the password they provided
baohua (Fri, 23 Jun 2017 03:23:06 GMT):
instead of only accepting randomly generate one from the server part.
baohua (Fri, 23 Jun 2017 03:23:14 GMT):
anyone would like to help on this?
baohua (Fri, 23 Jun 2017 03:24:33 GMT):
aha, @wangdong guess u would like to pick this!
wangdong (Fri, 23 Jun 2017 03:24:58 GMT):
I will have to finish the e2e first.
baohua (Fri, 23 Jun 2017 03:24:59 GMT):
very helpful to understand the e2e workflow by fixing this
wangdong (Fri, 23 Jun 2017 03:24:59 GMT):
haha
baohua (Fri, 23 Jun 2017 03:25:25 GMT):
ok, so anyone else to fix this one?
baohua (Fri, 23 Jun 2017 03:25:30 GMT):
https://jira.hyperledger.org/browse/FAB-3165
baohua (Fri, 23 Jun 2017 03:25:43 GMT):
OK, if nobody takes, i will eat it!
baohua (Fri, 23 Jun 2017 03:25:59 GMT):
great discussions and progress this week, that's all the agenda
baohua (Fri, 23 Jun 2017 03:26:10 GMT):
any else to discuss? @grapebaba
baohua (Fri, 23 Jun 2017 03:27:09 GMT):
anyone have issue to discuss more?
baohua (Fri, 23 Jun 2017 03:27:09 GMT):
anyone has issue to discuss more?
grapebaba (Fri, 23 Jun 2017 03:27:18 GMT):
there are a lot of changes with our previous implementation such as msp, identity, user
baohua (Fri, 23 Jun 2017 03:27:41 GMT):
aha, mostly, we move the membership part to a seperate dir named fabric-ca
grapebaba (Fri, 23 Jun 2017 03:27:44 GMT):
and some new underlying component added
grapebaba (Fri, 23 Jun 2017 03:27:55 GMT):
such as block decoder
baohua (Fri, 23 Jun 2017 03:27:56 GMT):
and the main part keeps as in the fabric dir
grapebaba (Fri, 23 Jun 2017 03:28:33 GMT):
i think we need revisit these underlying component first
baohua (Fri, 23 Jun 2017 03:28:38 GMT):
and the mvp (support chaincode operations) is with the highest priority
baohua (Fri, 23 Jun 2017 03:28:55 GMT):
@grapebaba more details?
grapebaba (Fri, 23 Jun 2017 03:29:18 GMT):
i do not think we can implement mvp without these components
baohua (Fri, 23 Jun 2017 03:29:58 GMT):
any reason?
grapebaba (Fri, 23 Jun 2017 03:30:10 GMT):
i just check the code
grapebaba (Fri, 23 Jun 2017 03:30:21 GMT):
for implement create channel
baohua (Fri, 23 Jun 2017 03:30:25 GMT):
suppose we assume having a joined channel by docker-compose and scripts.
grapebaba (Fri, 23 Jun 2017 03:30:30 GMT):
actually a lot of work need to do
baohua (Fri, 23 Jun 2017 03:31:11 GMT):
yeap, to avoid stucking, we can first use scripts to do the channel creation/joining work, does that make sense?
baohua (Fri, 23 Jun 2017 03:31:27 GMT):
as the official e2e does.
grapebaba (Fri, 23 Jun 2017 03:31:50 GMT):
i agree
baohua (Fri, 23 Jun 2017 03:32:00 GMT):
then it would be easier to finish the chaincode operations support. after that, we can focus on the channel staffs.
baohua (Fri, 23 Jun 2017 03:32:08 GMT):
as the channel part is still in-change....
baohua (Fri, 23 Jun 2017 03:32:19 GMT):
OK. any other issue?
grapebaba (Fri, 23 Jun 2017 03:32:50 GMT):
but i didn't check that if we can implement chaincode operation easily right now
baohua (Fri, 23 Jun 2017 03:33:28 GMT):
no worry, we will do it step by step: install first!
baohua (Fri, 23 Jun 2017 03:33:52 GMT):
@grapebaba would suggest u finish the install code (almost done)
baohua (Fri, 23 Jun 2017 03:33:52 GMT):
@grapebaba would suggest u help finish the install code (almost done)
baohua (Fri, 23 Jun 2017 03:34:05 GMT):
and then instantiate
baohua (Fri, 23 Jun 2017 03:35:10 GMT):
@wangdong anything to say?
wangdong (Fri, 23 Jun 2017 03:35:17 GMT):
I saw the chang log is outdated for long. I think if some one makes the changes, he is responsible to update it. It will be helpful for other to understand the work.
baohua (Fri, 23 Jun 2017 03:35:18 GMT):
saw u're in typing status
baohua (Fri, 23 Jun 2017 03:35:35 GMT):
aha, good suggestion!
baohua (Fri, 23 Jun 2017 03:35:49 GMT):
@lafenicecc could u help create a jira task for that?
baohua (Fri, 23 Jun 2017 03:35:58 GMT):
we need to update the changelog accordingly
lafenicecc (Fri, 23 Jun 2017 03:36:02 GMT):
ok
baohua (Fri, 23 Jun 2017 03:36:09 GMT):
anyone wanna help fix it right now?
wangdong (Fri, 23 Jun 2017 03:37:19 GMT):
shall we have a rule to let the everyone to take care of his part?
grapebaba (Fri, 23 Jun 2017 03:37:23 GMT):
shall we have a design disccusion
grapebaba (Fri, 23 Jun 2017 03:37:30 GMT):
at some time
grapebaba (Fri, 23 Jun 2017 03:37:51 GMT):
before that, we need every look at the node or java SDK
baohua (Fri, 23 Jun 2017 03:38:03 GMT):
ok, @grapebaba pls help org one and negotiate a time slot within the group
grapebaba (Fri, 23 Jun 2017 03:38:05 GMT):
I have several questions
baohua (Fri, 23 Jun 2017 03:38:51 GMT):
u may use phone call for that :)
grapebaba (Fri, 23 Jun 2017 03:39:02 GMT):
yes
baohua (Fri, 23 Jun 2017 03:39:15 GMT):
Ok, any more issue for the meeting today?
baohua (Fri, 23 Jun 2017 03:40:13 GMT):
OK. if no more issue, will end the meeting, thanks every attendee and have a nice weekend!

ok
baohua (Fri, 14 Jul 2017 03:06:36 GMT):
@wangdong any problem with https://jira.hyperledger.org/browse/FAB-2871?
WeiHu (Fri, 14 Jul 2017 03:07:00 GMT):
I've communicated with kai, and we agreed that this task should wait `install chaincode` task done
baohua (Fri, 14 Jul 2017 03:07:16 GMT):
OK, then pls add the comments in jira board
baohua (Fri, 14 Jul 2017 03:07:31 GMT):
we need to explore the status of the work :thinking:
wangdong (Fri, 14 Jul 2017 03:08:02 GMT):
last week, I got two patches related to client
wangdong (Fri, 14 Jul 2017 03:08:20 GMT):
one sent, the other is on the way
baohua (Fri, 14 Jul 2017 03:08:30 GMT):
yeap, and hope we can have the e2e doc/framework soon :)
WeiHu (Fri, 14 Jul 2017 03:08:40 GMT):
ok
baohua (Fri, 14 Jul 2017 03:08:43 GMT):
https://jira.hyperledger.org/browse/FAB-2871 is very important for users
wangdong (Fri, 14 Jul 2017 03:08:50 GMT):
this is the warm up, I will focus on e2e then
baohua (Fri, 14 Jul 2017 03:08:51 GMT):
thanks
wangdong (Fri, 14 Jul 2017 03:08:51 GMT):
OK
baohua (Fri, 14 Jul 2017 03:09:10 GMT):
and thanks to @tonyyang132 https://jira.hyperledger.org/browse/FAB-4592 is done!
wangdong (Fri, 14 Jul 2017 03:09:11 GMT):
Sorry for the long delay
baohua (Fri, 14 Jul 2017 03:09:29 GMT):
pls also help make sure we keep sync with the fabric 1.0 release.
baohua (Fri, 14 Jul 2017 03:09:39 GMT):
:train:
tonyyang132 (Fri, 14 Jul 2017 03:09:47 GMT):
@baohua sure, will look into it
baohua (Fri, 14 Jul 2017 03:10:07 GMT):
@lafenicecc how's going with https://jira.hyperledger.org/browse/FAB-4822?
baohua (Fri, 14 Jul 2017 03:10:43 GMT):
and hope u get familiar with the maintainer's responsibility, which is more challenging :woo:
lafenicecc (Fri, 14 Jul 2017 03:11:17 GMT):
Sorry a bit busy recently, but will get it done asap. BTW i'll invite two phd students to join us
baohua (Fri, 14 Jul 2017 03:11:34 GMT):
nice! hope they like Python!
lafenicecc (Fri, 14 Jul 2017 03:11:53 GMT):
yea.. one of them loves go more than python..
baohua (Fri, 14 Jul 2017 03:12:01 GMT):
aha, we got an open issue here today: https://jira.hyperledger.org/browse/FAB-4742
WeiHu (Fri, 14 Jul 2017 03:12:04 GMT):
:thumbsup:
baohua (Fri, 14 Jul 2017 03:12:10 GMT):
which Phd could pickup this one?
baohua (Fri, 14 Jul 2017 03:12:36 GMT):
PhD is valuable always :wink:
lafenicecc (Fri, 14 Jul 2017 03:13:02 GMT):
I'll let them handle this as a start
baohua (Fri, 14 Jul 2017 03:13:09 GMT):
great, thanks!
baohua (Fri, 14 Jul 2017 03:13:44 GMT):
aha, everything goes on as planed. so we do not have more on the agenda. Hope everyone are more clear during last week's design discussions.
baohua (Fri, 14 Jul 2017 03:14:00 GMT):
feel free to post any issue/question in the team during the contribution.
baohua (Fri, 14 Jul 2017 03:14:22 GMT):
So any more issue to discuss today? @grapebaba @lafenicecc
baohua (Fri, 14 Jul 2017 03:14:34 GMT):
and other members certainly
wangdong (Fri, 14 Jul 2017 03:14:55 GMT):
I got question regarding the org in client class
wangdong (Fri, 14 Jul 2017 03:15:24 GMT):
yesterday ,we have a short discussion about it
wangdong (Fri, 14 Jul 2017 03:15:32 GMT):
but i want know more about it
baohua (Fri, 14 Jul 2017 03:15:39 GMT):
yeap
wangdong (Fri, 14 Jul 2017 03:15:55 GMT):
As I found this org now is only used for user key in state store
wangdong (Fri, 14 Jul 2017 03:16:04 GMT):
any import use in other place ?
baohua (Fri, 14 Jul 2017 03:16:29 GMT):
u can simply think an org as a MSP, while MSP represent some identity.
baohua (Fri, 14 Jul 2017 03:16:49 GMT):
so the identity should be used in key related scenarios
baohua (Fri, 14 Jul 2017 03:17:14 GMT):
at the same time, the org is mostly in used in those id, key, permission checking scenarios.
baohua (Fri, 14 Jul 2017 03:17:27 GMT):
from client side, it should be with the identity related methods :)
wangdong (Fri, 14 Jul 2017 03:17:35 GMT):
ok
baohua (Fri, 14 Jul 2017 03:17:36 GMT):
is that clear for u?
wangdong (Fri, 14 Jul 2017 03:17:41 GMT):
yes
wangdong (Fri, 14 Jul 2017 03:17:59 GMT):
I try to restore the user from state store
baohua (Fri, 14 Jul 2017 03:18:10 GMT):
yes?
wangdong (Fri, 14 Jul 2017 03:18:18 GMT):
Then I have to use it to build the key
baohua (Fri, 14 Jul 2017 03:18:47 GMT):
if u need it, then feel free to create some Organization class
grapebaba (Fri, 14 Jul 2017 03:19:25 GMT):
as mentioned state store
baohua (Fri, 14 Jul 2017 03:19:32 GMT):
i guess the node one doesn't have that concept although
grapebaba (Fri, 14 Jul 2017 03:19:48 GMT):
have another question
baohua (Fri, 14 Jul 2017 03:19:56 GMT):
actually, we finally may need to remove the states from client side
baohua (Fri, 14 Jul 2017 03:20:09 GMT):
it's a workaround currently using state store
grapebaba (Fri, 14 Jul 2017 03:20:46 GMT):
really?
wangdong (Fri, 14 Jul 2017 03:21:16 GMT):
sure
baohua (Fri, 14 Jul 2017 03:21:24 GMT):
i guess so, the client could be stateless
grapebaba (Fri, 14 Jul 2017 03:21:25 GMT):
where we save certs and private keys
wangdong (Fri, 14 Jul 2017 03:21:26 GMT):
I just got a phone
baohua (Fri, 14 Jul 2017 03:21:55 GMT):
it may use some external store
baohua (Fri, 14 Jul 2017 03:22:14 GMT):
but the sdk itself should not manage this store in future, how do u think?
baohua (Fri, 14 Jul 2017 03:22:37 GMT):
i remember u got a question to discuss @grapebaba
grapebaba (Fri, 14 Jul 2017 03:23:34 GMT):
ok, sdk already provide state store interface
baohua (Fri, 14 Jul 2017 03:23:44 GMT):
yes?
wangdong (Fri, 14 Jul 2017 03:24:54 GMT):
the state store in sdk may be the front end, the back end can be pluggable?
grapebaba (Fri, 14 Jul 2017 03:26:08 GMT):
user enrollement and MSP files should be all certs and priv key files
grapebaba (Fri, 14 Jul 2017 03:26:30 GMT):
must store in security way i think
baohua (Fri, 14 Jul 2017 03:26:44 GMT):
yeap
baohua (Fri, 14 Jul 2017 03:26:57 GMT):
we can enhance the security later, that's must
grapebaba (Fri, 14 Jul 2017 03:28:04 GMT):
ok
qiang0723 (Fri, 14 Jul 2017 03:28:13 GMT):
supplement: I set up a task to adjust the environment to meet the needs of development and testing, https://jira.hyperledger.org/browse/FAB-5121, and plan the following environmental adjustment can be placed under this task, any suggestions?
baohua (Fri, 14 Jul 2017 03:28:52 GMT):
sure, can continue with this on env improvement
qiang0723 (Fri, 14 Jul 2017 03:29:04 GMT):
ok
baohua (Fri, 14 Jul 2017 03:29:19 GMT):
ok, any other question to discuss?
baohua (Fri, 14 Jul 2017 03:29:50 GMT):
If no more issue, will end the meeting, thanks every attendee and have a nice weekend!
tonyyang132 (Fri, 14 Jul 2017 03:30:13 GMT):

@luj
baohua (Fri, 28 Jul 2017 03:07:20 GMT):
dong, can u help update the status on https://jira.hyperledger.org/browse/FAB-2871?
wangdong (Fri, 28 Jul 2017 03:07:36 GMT):
I will finish the first sub task this week. Some basic confused me a lot. I have figure out them.
wangdong (Fri, 28 Jul 2017 03:07:38 GMT):
Ok
baohua (Fri, 28 Jul 2017 03:07:55 GMT):
ok, is there any question u wanna ask now?
baohua (Fri, 28 Jul 2017 03:08:02 GMT):
or issues to discuss?
baohua (Fri, 28 Jul 2017 03:08:24 GMT):
i guess for the e2e, we can first have some quick doc and framework code.
wangdong (Fri, 28 Jul 2017 03:09:05 GMT):
OK
baohua (Fri, 28 Jul 2017 03:09:23 GMT):
feel free to drop out question if there's :)
baohua (Fri, 28 Jul 2017 03:09:30 GMT):
:hibiscus:
wangdong (Fri, 28 Jul 2017 03:09:36 GMT):
I was confused by the relation ship between the nodes
wangdong (Fri, 28 Jul 2017 03:09:44 GMT):
when the docker compose up
baohua (Fri, 28 Jul 2017 03:09:52 GMT):
nodes? u mean peer node or orderer node?
wangdong (Fri, 28 Jul 2017 03:09:56 GMT):
yes
wangdong (Fri, 28 Jul 2017 03:10:17 GMT):
they are just working but no relation with each other I think
baohua (Fri, 28 Jul 2017 03:10:31 GMT):
aha, @grapebaba any quick comments?
grapebaba (Fri, 28 Jul 2017 03:11:16 GMT):
not understand your question
baohua (Fri, 28 Jul 2017 03:11:30 GMT):
IMHO, those peers work together as the fabric network, to provide service. so they should have relationship.
baohua (Fri, 28 Jul 2017 03:12:13 GMT):
can u elaborate ur question?
baohua (Fri, 28 Jul 2017 03:13:10 GMT):
@wangdong
wangdong (Fri, 28 Jul 2017 03:13:37 GMT):
我在想怎么把问题说清楚
baohua (Fri, 28 Jul 2017 03:14:12 GMT):
sure, take ur time. meanwhile, i'm working on https://jira.hyperledger.org/browse/FAB-3165
baohua (Fri, 28 Jul 2017 03:14:28 GMT):
now need the last part of using signingidentity to make an auth token
baohua (Fri, 28 Jul 2017 03:14:42 GMT):
hopefully can finish the register functionality soon.
baohua (Fri, 28 Jul 2017 03:15:15 GMT):
Another item is the license header
baohua (Fri, 28 Jul 2017 03:15:18 GMT):
https://jira.hyperledger.org/browse/FAB-4742
baohua (Fri, 28 Jul 2017 03:15:33 GMT):
We need to add/check the header for every code/doc
baohua (Fri, 28 Jul 2017 03:16:01 GMT):
@lujiang has some experience, hopefully she can help this work
baohua (Fri, 28 Jul 2017 03:16:23 GMT):
:woo: @wangdong ready for ur question, now?
wangdong (Fri, 28 Jul 2017 03:16:26 GMT):
有一个操作，我比较看困惑，在做这个测试的时候，node sdk 需要把配置文件的所有node enroll.如果他们都在网络而且互相有关系，那他们肯定已经enroll 了，为什么还要enroll。
wangdong (Fri, 28 Jul 2017 03:16:57 GMT):
enroll我理解就是把节点在ca注册，获得身份
baohua (Fri, 28 Jul 2017 03:17:02 GMT):
enroll means to let the fabric network recognize the client.
baohua (Fri, 28 Jul 2017 03:17:15 GMT):
each client is independent with each other.
baohua (Fri, 28 Jul 2017 03:17:25 GMT):
so every client need to enroll himself.
baohua (Fri, 28 Jul 2017 03:17:58 GMT):
so is this answering ur question?
wangdong (Fri, 28 Jul 2017 03:18:02 GMT):
但是这些节点在docker compose 起来的时候不是都已经在网络里面了么
wangdong (Fri, 28 Jul 2017 03:18:34 GMT):
你的意思是当客户端链接这些节点的时候比如重新enroll?
baohua (Fri, 28 Jul 2017 03:18:37 GMT):
yeap, in this case, these nodes work like client to enroll themselves.
wangdong (Fri, 28 Jul 2017 03:18:42 GMT):
必须
baohua (Fri, 28 Jul 2017 03:18:46 GMT):
nooo.
baohua (Fri, 28 Jul 2017 03:19:43 GMT):
to keep the e2e case more simple, we can simple write down like : 1) client enrolls in the network; 2) client installs a chaincode to some peer; 3) client instantiates the chaincode; 4) client invokes the chaincode.
baohua (Fri, 28 Jul 2017 03:19:52 GMT):
does this make sense?
baohua (Fri, 28 Jul 2017 03:20:11 GMT):
more details can be added after we pass through the basic workflow.
wangdong (Fri, 28 Jul 2017 03:20:29 GMT):
so when the compose up ,these nodes are not enrolled, right
wangdong (Fri, 28 Jul 2017 03:20:33 GMT):
?
baohua (Fri, 28 Jul 2017 03:20:58 GMT):
if u mean the compose.yaml inside sdk-py project, yes, no need to enroll them.
baohua (Fri, 28 Jul 2017 03:21:15 GMT):
only client sdk needs to enroll now.
baohua (Fri, 28 Jul 2017 03:21:23 GMT):
@grapebaba any comments?
grapebaba (Fri, 28 Jul 2017 03:22:18 GMT):
i haven't seen those codes
baohua (Fri, 28 Jul 2017 03:22:45 GMT):
@wangdong any more confusing now?
grapebaba (Fri, 28 Jul 2017 03:23:07 GMT):
since CA is not necessary, i assume nodes no need to enroll when docker-compose up
wangdong (Fri, 28 Jul 2017 03:23:35 GMT):
OK, 我问的简洁些，当compose up 的时候，这些节点已经enroll了。我在操作的时候不需要重新enroll 了哈
grapebaba (Fri, 28 Jul 2017 03:23:58 GMT):
应该没有enroll
baohua (Fri, 28 Jul 2017 03:23:58 GMT):
yeap, enroll once, then u will get all the required cert/key files.
baohua (Fri, 28 Jul 2017 03:23:58 GMT):
yeap, client enrolls once, then u will get all the required cert/key files.
grapebaba (Fri, 28 Jul 2017 03:24:13 GMT):
因为可以 不要ca
grapebaba (Fri, 28 Jul 2017 03:24:26 GMT):
也能启动网络
baohua (Fri, 28 Jul 2017 03:24:50 GMT):
@wangdong the sdk-py is to design a client sdk, so u do not need to care the peer nodes, actually.
wangdong (Fri, 28 Jul 2017 03:25:32 GMT):
嗯， 我只想搞清楚他们怎么工作的。不然我只能依照node 来写。
baohua (Fri, 28 Jul 2017 03:25:32 GMT):
any more issue?
baohua (Fri, 28 Jul 2017 03:26:02 GMT):
aha, then suggest u have a look at our documentation
grapebaba (Fri, 28 Jul 2017 03:26:03 GMT):
你把代码位置发来看看
wangdong (Fri, 28 Jul 2017 03:26:14 GMT):
OK
baohua (Fri, 28 Jul 2017 03:26:21 GMT):
Here's lot! https://wiki.hyperledger.org/groups/twgc/team_ie
wangdong (Fri, 28 Jul 2017 03:26:29 GMT):
我是先看node 再想着实现py
baohua (Fri, 28 Jul 2017 03:26:52 GMT):
somehow, the node one is very complicated, can just use as a reference.
baohua (Fri, 28 Jul 2017 03:27:09 GMT):
have a quick look, then good enough
baohua (Fri, 28 Jul 2017 03:27:20 GMT):
OK, any more issues from everyone?
wangdong (Fri, 28 Jul 2017 03:27:31 GMT):

@baohua i am not sure i can answer this question
baohua (Fri, 18 Aug 2017 03:15:57 GMT):
OK, let me try to help @wangdong
baohua (Fri, 18 Aug 2017 03:16:17 GMT):
Typically, for an org, we now have two permission level: admin and member.
baohua (Fri, 18 Aug 2017 03:16:42 GMT):
While in a fabric network, we can have various roles, like a client, user, peer, etc.
baohua (Fri, 18 Aug 2017 03:16:58 GMT):
sometimes, a role may be bind with a permission level
baohua (Fri, 18 Aug 2017 03:17:07 GMT):
but that's not restricted to.
baohua (Fri, 18 Aug 2017 03:17:18 GMT):
is that clear now?
wangdong (Fri, 18 Aug 2017 03:17:58 GMT):
not so clear
wangdong (Fri, 18 Aug 2017 03:18:10 GMT):
maybe more talk in meetup
baohua (Fri, 18 Aug 2017 03:18:12 GMT):
sure, keep asking :)
baohua (Fri, 18 Aug 2017 03:18:28 GMT):
feel free to drop in maillist and also group channels
wangdong (Fri, 18 Aug 2017 03:18:37 GMT):

baohua (Fri, 18 Aug 2017 03:18:40 GMT):

baohua (Fri, 18 Aug 2017 03:18:56 GMT):
OK, so that's all planed agenda.
baohua (Fri, 18 Aug 2017 03:19:02 GMT):
Anything else?
baohua (Fri, 18 Aug 2017 03:20:27 GMT):
@david_dornseifer wanna say sth?
david_dornseifer (Fri, 18 Aug 2017 03:20:29 GMT):
guess i'll update the readme soon so that we can point out how to run the unit test and flake8 separate from the integration tests so we can make sure that all patches are validated by flake8
baohua (Fri, 18 Aug 2017 03:20:52 GMT):
Great idea, feel free to create jira task and work on it :)
david_dornseifer (Fri, 18 Aug 2017 03:21:03 GMT):
job builder complained about missing whitespaces etc. allot :)
baohua (Fri, 18 Aug 2017 03:21:08 GMT):
Everyone is encouraged to find and address problem/issues
baohua (Fri, 18 Aug 2017 03:21:18 GMT):
haha, blood due to whitespace
baohua (Fri, 18 Aug 2017 03:21:29 GMT):
OK, any more issue to discuss today?
david_dornseifer (Fri, 18 Aug 2017 03:21:48 GMT):
sry not missing whitespaced, additional whitespaces :)
baohua (Fri, 18 Aug 2017 03:21:56 GMT):
our `make check` locally should find the whitespace issue
david_dornseifer (Fri, 18 Aug 2017 03:22:11 GMT):
yes but that also triggers the integration tests
baohua (Fri, 18 Aug 2017 03:22:17 GMT):
right
david_dornseifer (Fri, 18 Aug 2017 03:22:22 GMT):
and that takes allot of time
baohua (Fri, 18 Aug 2017 03:22:33 GMT):
we suggest all patchset pass local check before submission
baohua (Fri, 18 Aug 2017 03:23:00 GMT):
got ur idea now, maybe can fail after checking grammar
baohua (Fri, 18 Aug 2017 03:23:18 GMT):
stop from running more testing
david_dornseifer (Fri, 18 Aug 2017 03:23:49 GMT):
yea just for faster development i think we should have `tox -v flake8` written on the readme
david_dornseifer (Fri, 18 Aug 2017 03:24:13 GMT):
but yes agree to submit a patch make check should be successful
baohua (Fri, 18 Aug 2017 03:24:17 GMT):
sure, and still pass all testing before submission -:)
baohua (Fri, 18 Aug 2017 03:24:53 GMT):
OK, any more issue? @wangdong @grapebaba @qiang0723
wangdong (Fri, 18 Aug 2017 03:25:02 GMT):
no
qiang0723 (Fri, 18 Aug 2017 03:25:08 GMT):

wangdong (Sat, 19 Aug 2017 16:45:17 GMT):
@david_dornseifer Hi, when I tried to address all the comments of my first patch of e2e test, I have to make some modification to channel class and I implemented the create_channel feature. But @grapebaba says you are on this task. I just want to ask if you have finished this, if so, you can push your patch. If not, can I push my patch for review? And let's discuss it.
david_dornseifer (Mon, 21 Aug 2017 00:17:55 GMT):
@wangdong yes working on it right now, pretty much implementing some unit / integration tests for the create_channel function. You can go ahead and push the patch and we can go from there, also it would be easier for me to write the integration tests if there are already as set of e2e utils
wangdong (Mon, 21 Aug 2017 00:40:04 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=xnvg8WHwwFx2XqaoF) @david_dornseifer OK. I will push the patch then. It is ready.
david_dornseifer (Wed, 23 Aug 2017 00:08:03 GMT):
hi, running into the following issue right now establishing a secure tls connection to the orderer
david_dornseifer (Wed, 23 Aug 2017 00:08:04 GMT):
2017-08-23 00:05:45.852 UTC [grpc] Printf -> DEBU 0f6 grpc: Server.Serve failed to complete security handshake from "172.23.0.1:41436": tls: no cipher suite supported by
both client and server
david_dornseifer (Wed, 23 Aug 2017 00:08:43 GMT):
on the client side it looks like `E0822 17:05:45.851592000 123145409613824 ssl_transport_security.c:940] Handshake failed with fatal error SSL_ERROR_SSL: error:10000410:SSL routines:OPENSSL_internal:SSLV3_ALERT_HANDSHAKE_FAILURE.

david_dornseifer (Wed, 23 Aug 2017 00:10:28 GMT):
any idea about that?, thought it might be related to the openssl version but using 1.02 has not changed anything
david_dornseifer (Wed, 23 Aug 2017 00:10:50 GMT):
grpc == 1.4.0 / orderer binary is 1.0.0
david_dornseifer (Wed, 23 Aug 2017 00:10:50 GMT):
grpcio == 1.4.0 / orderer binary is 1.0.0
baohua (Wed, 23 Aug 2017 01:58:26 GMT):
are u using the fabric 1.0 images? It does look like an SSL handshake problem, cannot find agreed version between client and server
david_dornseifer (Thu, 24 Aug 2017 00:53:43 GMT):
Ok, fixed that issue :) - the cipher suite needs to be present in an environment variable os.environ['GRPC_SSL_CIPHER_SUITES'] = 'ECDHE-RSA-AES128-GCM-SHA256:' \
'ECDHE-RSA-AES128-SHA256:' \

By saying "has been committed into a block", does it mean that the orderer has put this transaction into a block? Or it means every peer has accepted this block and committed into their copy of the ledger?
baohua (Fri, 25 Aug 2017 01:13:05 GMT):
(Sorry was blocked yesterday...) Dear all, we will cancel the meeting on today morning, pls keep on existing patchsets and sync offline, thanks!
david_dornseifer (Fri, 25 Aug 2017 17:19:03 GMT):
hi, is there a specific reason that we have six private keys for each user/peer/org etc. in our e2e folders? there is only one matching x509 cert on the other side
david_dornseifer (Fri, 25 Aug 2017 17:19:30 GMT):
will delete the not matching ones with the next patch

grapebaba (Wed, 30 Aug 2017 08:08:10 GMT):
there is a duplicate method
david_dornseifer (Wed, 30 Aug 2017 16:12:46 GMT):
@ grapebaba - as written in the comments the duplicate method should be deleted with the chaincode refactoring, right now its imported directly into channel/installment.py, instantiation.py, invocation.py, transactionproposals.py ....
david_dornseifer (Wed, 30 Aug 2017 16:13:35 GMT):
my patch was already so big, thought this should be fixed with the next chaincode deployment patch then since that those modules need refactoring anyway
david_dornseifer (Wed, 30 Aug 2017 16:14:37 GMT):
@grapebaba what do you think?
wangdong (Thu, 31 Aug 2017 06:21:31 GMT):
@david_dornseifer Hi, David. Just some concern. Actually, the FAB-3483 and your patch set got some overlapped by which I mean
our patches all implementes the "creating channel". My implementation is a little java flavor. I referred to the java sdk a lot.
I can see yours is javascript style. But your code is superb. I really admire that. Well, my point is you may not review my
patches. And the overlapped part always wastes our time. we did the duplicated job. And I have asked you about this job status.
I thought you knew what i have done. So my advice is, as a maintainer, you can always review the patch. And give the your advice,
if something is not that perfect. we can spend time discussing. Let's just make it better together. And no waste time on the duplicated
work.
grapebaba (Thu, 31 Aug 2017 08:35:30 GMT):
@david_dornseifer OK
grapebaba (Thu, 31 Aug 2017 08:36:08 GMT):
also please take a look if we can avoid use env
grapebaba (Thu, 31 Aug 2017 08:39:03 GMT):
@wangdong we can do further refactor if needed
grapebaba (Thu, 31 Aug 2017 08:40:22 GMT):
you are familiar with the process of create channel, actually no waste time
baohua (Thu, 31 Aug 2017 10:15:36 GMT):

david_dornseifer (Fri, 08 Sep 2017 03:10:28 GMT):
what i saw from the channel patch we have to add some more unit tests to stabilize the code
baohua (Fri, 08 Sep 2017 03:10:48 GMT):
yes UT is necessary!
baohua (Fri, 08 Sep 2017 03:11:05 GMT):
fabric just release v1.0.2
baohua (Fri, 08 Sep 2017 03:11:30 GMT):
but i guess we can stay on top of v1.0, unless meeting any problem, thoughts?
david_dornseifer (Fri, 08 Sep 2017 03:12:13 GMT):
guess that should be fine to implement the basics at least
baohua (Fri, 08 Sep 2017 03:12:29 GMT):

any idea on that?
baohua (Sat, 09 Sep 2017 00:47:02 GMT):
seems a permission problem, can u reach @rjones for helping check?

rjones (Sat, 09 Sep 2017 00:48:36 GMT):
@jwagantall - isn't tox built in to the images?
rjones (Sat, 09 Sep 2017 00:48:49 GMT):
@david_dornseifer link to a specific build please?
jwagantall (Sat, 09 Sep 2017 00:49:06 GMT):
should be.. let me confirm
rjones (Sat, 09 Sep 2017 00:49:34 GMT):
I mean, `tox` has been part of the images since maybe not day one but a long time ago
jwagantall (Sat, 09 Sep 2017 00:52:35 GMT):
yes.. i can see it here in provision/docker.sh
jwagantall (Sat, 09 Sep 2017 00:52:36 GMT):
# Tox for py-sdk
PACKAGES="$PACKAGES tox"
rjones (Sat, 09 Sep 2017 00:53:51 GMT):
oh wait, it's `pluggy` that's failing
david_dornseifer (Sat, 09 Sep 2017 17:05:05 GMT):
@rjones @jwagantall just to give you a little bit more context https://jenkins.hyperledger.org/job/fabric-sdk-py-verify-x86_64/227/console
david_dornseifer (Sat, 09 Sep 2017 17:06:20 GMT):
since that pluggy is missing tox cannot be installed and the check fails with ```tox -v -epylint test

tkuhrt (Thu, 14 Sep 2017 18:59:10 GMT):
@qiang0723 : We need to make sure that it is clear that the source code is licensed under Apache 2.0 and that the documentation for the project is licensed under CC-BY-4.0.
tkuhrt (Thu, 14 Sep 2017 19:00:34 GMT):
So while the README.md is covered by CC-BY-4.0, we also want people who are reading this to understand that the source code is licensed under Apache 2.0. We want people who want to contribute understand that they will need to contribute their source code under Apache 2.0 and their documentation under CC-BY-4.0.

baohua (Fri, 29 Sep 2017 03:10:52 GMT):
nice to hear that, would u like to pick some interesting one like the cc invoke operation?
baohua (Fri, 29 Sep 2017 03:11:06 GMT):
i guess there're already some codes to be done.
hanhzf (Fri, 29 Sep 2017 03:11:22 GMT):
Yes, we can pick up the invoke work
baohua (Fri, 29 Sep 2017 03:11:39 GMT):
thanks, zhaofang
baohua (Fri, 29 Sep 2017 03:11:45 GMT):
then i will assign this one https://jira.hyperledger.org/browse/FAB-5491?jql=project%20%3D%20FAB%20AND%20status%20in%20(%22In%20Progress%22%2C%20%22To%20Do%22)%20AND%20component%20%3D%20fabric-sdk-py to u
baohua (Fri, 29 Sep 2017 03:12:14 GMT):
basically, u can create an env by peer cli cmds
hanhzf (Fri, 29 Sep 2017 03:12:16 GMT):
Will start travel from tmr, start working on it after national holiday, will that be ok ?
baohua (Fri, 29 Sep 2017 03:12:39 GMT):

this one: https://jira.hyperledger.org/browse/FAB-5489
baohua (Fri, 29 Sep 2017 03:14:57 GMT):
kai already finish the install steps, i guess it's similar process code
tonyyang132 (Fri, 29 Sep 2017 03:15:22 GMT):
OK, I guess I could take that
baohua (Fri, 29 Sep 2017 03:15:31 GMT):
thanks, assign to u

grapebaba (Fri, 29 Sep 2017 03:20:37 GMT):
sure
bryanhuang (Fri, 29 Sep 2017 03:20:47 GMT):
I can pick up cc upgrade, since it similar with https://jira.hyperledger.org/browse/FAB-3783
tonyyang132 (Fri, 29 Sep 2017 03:20:47 GMT):
thanks in advance @grapebaba
baohua (Fri, 29 Sep 2017 03:20:55 GMT):
i saw @wangdong is working on FAB-5488
grapebaba (Fri, 29 Sep 2017 03:21:07 GMT):
i will clean up some code which not used
baohua (Fri, 29 Sep 2017 03:21:10 GMT):
@bryanhuang thanks a lot!
bryanhuang (Fri, 29 Sep 2017 03:21:55 GMT):
but its depends on the instantiate operation, I will start the work once instantiation done.
baohua (Fri, 29 Sep 2017 03:22:01 GMT):
@bryanhuang seems we do not have that task yet? pls help create a jira task about it and assign to urself.
baohua (Fri, 29 Sep 2017 03:22:27 GMT):
yeap, upgrade is similar with instantiate, so pls collaborate closely with each other.
bryanhuang (Fri, 29 Sep 2017 03:22:53 GMT):
5490
baohua (Fri, 29 Sep 2017 03:23:03 GMT):
FAB-5490
tonyyang132 (Fri, 29 Sep 2017 03:23:10 GMT):
so https://jira.hyperledger.org/browse/FAB-5489 is about install and instantiate, did you mean the installation part is done? @baohua
baohua (Fri, 29 Sep 2017 03:23:19 GMT):
aha, maybe we can split that into two separate ones.
bryanhuang (Fri, 29 Sep 2017 03:23:25 GMT):
right
baohua (Fri, 29 Sep 2017 03:23:37 GMT):
@toddinpal yes, we will merge today after more reviews

baohua (Fri, 29 Sep 2017 03:23:51 GMT):

https://gerrit.hyperledger.org/r/#/q/project:fabric-sdk-py+AND+status:open
baohua (Fri, 29 Sep 2017 03:24:14 GMT):
Ok, again, everyone pls help review those patchsets, and add ur comments.
baohua (Fri, 29 Sep 2017 03:24:25 GMT):
Thanks :hatched_chick:
tonyyang132 (Fri, 29 Sep 2017 03:24:38 GMT):
OK I will. Is https://gerrit.hyperledger.org/r/#/c/11765/ about the install part of FAB-5489?
baohua (Fri, 29 Sep 2017 03:25:02 GMT):
yes, installation
baohua (Fri, 29 Sep 2017 03:25:19 GMT):
Ok, seems very good and efficient today. Anything else? @grapebaba
baohua (Fri, 29 Sep 2017 03:25:27 GMT):
and everyone else?
tonyyang132 (Fri, 29 Sep 2017 03:26:26 GMT):
so after I split FAB-5489, can I assign the install part to Chen Kai since he's finished coding?
grapebaba (Fri, 29 Sep 2017 03:27:00 GMT):
that task is for E2E test
grapebaba (Fri, 29 Sep 2017 03:27:10 GMT):
please check the parent task
baohua (Fri, 29 Sep 2017 03:27:16 GMT):
since kai is using the task number in the patchset, it's better u create one for instantiate separately?
baohua (Fri, 29 Sep 2017 03:27:26 GMT):
and modify the original task to install only.
baohua (Fri, 29 Sep 2017 03:27:35 GMT):
make sense? @grapebaba
grapebaba (Fri, 29 Sep 2017 03:27:41 GMT):
no
grapebaba (Fri, 29 Sep 2017 03:27:55 GMT):
i don't use this task
grapebaba (Fri, 29 Sep 2017 03:28:12 GMT):
this task is for E2E test created by @wangdong
baohua (Fri, 29 Sep 2017 03:28:18 GMT):
aha, FAB-5151
grapebaba (Fri, 29 Sep 2017 03:28:47 GMT):
@tonyyang132 you can create a new task for instaniate
baohua (Fri, 29 Sep 2017 03:28:49 GMT):
@tonyyang132 just help keep the task number in gerrit is the same with those at jira.
baohua (Fri, 29 Sep 2017 03:28:51 GMT):
Thanks
tonyyang132 (Fri, 29 Sep 2017 03:29:12 GMT):
OK
baohua (Fri, 29 Sep 2017 03:29:20 GMT):

baohua (Fri, 29 Sep 2017 03:30:11 GMT):

grapebaba (Fri, 29 Sep 2017 03:30:22 GMT):

wangdong (Sat, 30 Sep 2017 02:16:50 GMT):
I got a idea that I will refectory the e2e test framework. Because when I try to complete the join channel part. I found the the other parts will depend on the creating channel part. That means other test case will have to use the channel created at the first place. The framework now can not do that. Every time the docker envir

I got a idea that I will refectory the e2e test framework. Because when I try to complete the join channel part. I found the the other parts will depend on the creating channel part. That means other test case will have to use the channel created at the first place. The framework now can not do that. Every time the docker environment is up, it is fresh. So I would like to integrate all the test cases into one class and each case will be a method. And there should be another e2e test util file in which there are some helper function to support the e2e test. any comments will be appreciated. Thanks'
baohua (Sat, 30 Sep 2017 06:09:23 GMT):
@wangdong in that case, i suppose we can boot up the network, and use scripts to prepare for the channel, like the official e2e examples?
BernardLin (Sun, 01 Oct 2017 18:29:30 GMT):
Has joined the channel.
grapebaba (Mon, 02 Oct 2017 23:55:36 GMT):
@wangdong i think we should differentiate e2e and integration test, i'd like integration test independent one by one. And do e2e test using your approach
wangdong (Fri, 06 Oct 2017 10:24:58 GMT):
Thanks for the advice. I will have a look which is better.

@grapebaba @baohua recently we have made some changes to pip installation packages and updated CI build nodes for testing in sandbox (See change here https://github.com/hyperledger/ci-management/blob/master/packer/provision/docker.sh#L161) I see fabric behave tests are working as expected on python 2.7 version but I see tox installation is failed.. see the error log here.. https://jenkins.hyperledger.org/sandbox/job/fabric-sdk-py-verify-x86_64/3/console
rameshthoomu (Tue, 17 Oct 2017 01:08:32 GMT):
Could you let me know what is wrong here..
rameshthoomu (Tue, 17 Oct 2017 01:10:11 GMT):
also see this change https://gerrit.hyperledger.org/r/#/c/14487/2/packer/provision/docker.sh
baohua (Tue, 17 Oct 2017 02:39:48 GMT):
@rameshthoomu from the log, i found some error like `18:21:07 OSError: [Errno 13] Permission denied: '/usr/local/lib/python2.7/dist-packages/pluggy-0.5.2.dist-info'
`. Will this cause the installation failure? I remember ry has upgrade the ci with pluggy integrated?
rameshthoomu (Tue, 17 Oct 2017 02:41:54 GMT):
It’s installing on 2.7 version.. is that the problem? I don’t see any issue in production CI nodes
rameshthoomu (Tue, 17 Oct 2017 02:43:58 GMT):
I managed to install pluggy in sandbox but I could see tox command not found error https://jenkins.hyperledger.org/sandbox/job/fabric-sdk-py-verify-x86_64/4/console

rameshthoomu (Wed, 18 Oct 2017 16:09:25 GMT):
@jwagantall after the new image is updated I could see below error in fabric-sdk-py verify jobs
```

hmmm .. will look into that too..

@baohua earlier default python version is 3.5.. with the recent changes it changed to python2.7 for fabric-behave tests..

baohua (Fri, 03 Nov 2017 03:00:00 GMT):
seems no more else, let's do some quick sync
baohua (Fri, 03 Nov 2017 03:00:19 GMT):
recently i found an interesting gosdk project: https://github.com/CognitionFoundry/gohfc
baohua (Fri, 03 Nov 2017 03:00:34 GMT):
people use it to give some perf evaluate result (non-official)
baohua (Fri, 03 Nov 2017 03:00:53 GMT):
i guess we can have a look at it too, which is really simple in design.
baohua (Fri, 03 Nov 2017 03:01:09 GMT):
thoughts? @grapebaba
grapebaba (Fri, 03 Nov 2017 03:01:24 GMT):
well
grapebaba (Fri, 03 Nov 2017 03:02:07 GMT):
what is the main difference with official go-sdk?
baohua (Fri, 03 Nov 2017 03:02:34 GMT):
not too much, the key advantage is that it's simple and basic
baohua (Fri, 03 Nov 2017 03:03:08 GMT):
donot know whether they will contribute to community
grapebaba (Fri, 03 Nov 2017 03:04:00 GMT):
good, will see
baohua (Fri, 03 Nov 2017 03:04:09 GMT):
And besides chaincode installation, do u know how's going on @tonyyang132 's work on chaincode instantiate?
grapebaba (Fri, 03 Nov 2017 03:04:32 GMT):
indeed all SDKs currently more complex
baohua (Fri, 03 Nov 2017 03:04:36 GMT):
@hanhzf is working on chaincode invoke
baohua (Fri, 03 Nov 2017 03:04:40 GMT):
Agree!
baohua (Fri, 03 Nov 2017 03:04:51 GMT):
we need to provide something easy to use first
grapebaba (Fri, 03 Nov 2017 03:04:57 GMT):

wangdong (Fri, 03 Nov 2017 13:22:53 GMT):
@grapebaba @baohua As I read the log, I found the channel is created, but when to get the genesis block, it says, channel not found. [orderer/multichain] newChain -> INFO 7fc Created and starting new chain businesschannel. But I also found this: Rejecting deliver because channel 47d89f6043aa5ccfa836fbc6673ccd101c2f1f11a0f77b149b2e013e90b8ad9c not found
wangdong (Fri, 03 Nov 2017 13:25:19 GMT):
I also found another channel with id: testchanid. what is this? I am so busy recently. I have no time to read more about the code to look for the answer. You may have some clue.
grapebaba (Fri, 03 Nov 2017 13:26:32 GMT):
That's system channel
grapebaba (Fri, 03 Nov 2017 13:27:48 GMT):
Can you wait several time after create channel, then request get genesis block
grapebaba (Fri, 03 Nov 2017 13:29:37 GMT):
i also very busy these days

baohua (Fri, 17 Nov 2017 03:00:49 GMT):
we made quite good progress, having finished the chaincode install/channel creation.
baohua (Fri, 17 Nov 2017 03:01:05 GMT):
those can be nice reference for the further operations
baohua (Fri, 17 Nov 2017 03:01:28 GMT):

baohua (Fri, 17 Nov 2017 03:01:38 GMT):
FAB-5489
baohua (Fri, 17 Nov 2017 03:02:18 GMT):

baohua (Fri, 17 Nov 2017 03:02:38 GMT):
pity we do not have them online today
baohua (Fri, 17 Nov 2017 03:02:49 GMT):

david_dornseifer (Fri, 17 Nov 2017 03:03:08 GMT):

david_dornseifer (Fri, 17 Nov 2017 03:04:10 GMT):
:)
baohua (Fri, 17 Nov 2017 03:04:39 GMT):
any travel plan?
david_dornseifer (Fri, 17 Nov 2017 03:04:43 GMT):
should we upgrade the testing images to 1.0.4?
baohua (Fri, 17 Nov 2017 03:05:25 GMT):
do u think it's necessary?
baohua (Fri, 17 Nov 2017 03:05:39 GMT):
1.1-preview is released
david_dornseifer (Fri, 17 Nov 2017 03:06:23 GMT):
have not looked into that - many changes in the protos? / can test both with our current codebase and see if it works
baohua (Fri, 17 Nov 2017 03:06:45 GMT):
not too much change
baohua (Fri, 17 Nov 2017 03:07:05 GMT):
IMHO, it's nice-to-have, but won't need to spend too much effort, certainly
david_dornseifer (Fri, 17 Nov 2017 03:07:23 GMT):
yea think so too
baohua (Fri, 17 Nov 2017 03:07:32 GMT):
those channel/chaincode operations are waiting for us eagerly
baohua (Fri, 17 Nov 2017 03:07:54 GMT):
great!
david_dornseifer (Fri, 17 Nov 2017 03:08:16 GMT):
invoke and query would be nice to have :)
baohua (Fri, 17 Nov 2017 03:08:49 GMT):
any technical issue to discuss? i plan to refine the existing code architecture, which is way more complicated than expected. but maybe can wait for time till we have chaincode invocation and channel join
baohua (Fri, 17 Nov 2017 03:09:19 GMT):
@wangdong said he will finish the chaincode invocation soon
baohua (Fri, 17 Nov 2017 03:09:45 GMT):
really hard-working guy
david_dornseifer (Fri, 17 Nov 2017 03:10:01 GMT):
ok - agree we should wait with refactoring until the basic functions are there
baohua (Fri, 17 Nov 2017 03:10:27 GMT):
yes, but let's go on with those minor fixes
baohua (Fri, 17 Nov 2017 03:11:09 GMT):
ok, nothing too much from my side, just attend the membership summit, which attracts lots of eyeballs by fabric
baohua (Fri, 17 Nov 2017 03:11:31 GMT):
there will be lots of potential adoptions of our sdk
baohua (Fri, 17 Nov 2017 03:12:08 GMT):
anything else for u? @david_dornseifer
david_dornseifer (Fri, 17 Nov 2017 03:12:37 GMT):
second you opinion about the adoption
david_dornseifer (Fri, 17 Nov 2017 03:12:57 GMT):
and with 1.1 fabric will be much more attractive
baohua (Fri, 17 Nov 2017 03:13:09 GMT):
yes, the privacy protection
baohua (Fri, 17 Nov 2017 03:13:28 GMT):
we hope to finish the 1.0 sdk before fabric 1.1 release
david_dornseifer (Fri, 17 Nov 2017 03:13:53 GMT):
would be nice
baohua (Fri, 17 Nov 2017 03:14:11 GMT):
exactly
baohua (Fri, 17 Nov 2017 03:14:20 GMT):
ok, if nothing else, will end the meeting
baohua (Fri, 17 Nov 2017 03:14:35 GMT):

berserkr (Fri, 17 Nov 2017 06:38:50 GMT):
Hi Guys, how did you generate the channel.tx file for the py sdk?
berserkr (Fri, 17 Nov 2017 06:39:56 GMT):
I thought that channel information is created when we invoke the create channel APIs
berserkr (Fri, 17 Nov 2017 06:40:04 GMT):
is it created by the fabric or by the sdk?
david_dornseifer (Fri, 17 Nov 2017 18:18:05 GMT):
@berserkr the channel.tx is generated by the configtxgen tool in the fabric package
david_dornseifer (Fri, 17 Nov 2017 18:19:36 GMT):
this is independent from the sdks - for more questions regarding the channel.tx etc. you should check the #fabric channel
berserkr (Fri, 17 Nov 2017 18:37:15 GMT):
got it, thank you
berserkr (Fri, 17 Nov 2017 18:37:15 GMT):

and feel free to ask in the channel for help
grapebaba (Fri, 01 Dec 2017 03:06:50 GMT):

to let people manipulate blocks smoothly
grapebaba (Fri, 01 Dec 2017 03:11:05 GMT):
not heard before
baohua (Fri, 01 Dec 2017 03:11:29 GMT):
oh, when update config block, currently, need to use manual tools

like `jq`
baohua (Fri, 01 Dec 2017 03:12:36 GMT):

done
baohua (Mon, 11 Dec 2017 01:37:55 GMT):
@wangdong added comments: https://gerrit.hyperledger.org/r/#/c/16093/
baohua (Mon, 11 Dec 2017 01:40:02 GMT):
@david_dornseifer about the changelog.sh, i'm thinking whether it's possible to make it scan all history from the beginning and mark each release automatically? Now seems it only marks the previous_release, and do not care those elder release tags before that.
wangdong (Mon, 11 Dec 2017 03:29:25 GMT):
yes, I read them. All the chain code operation functions need the MSP support. I wonder if I can complete the test code after the implementation of MSP.
wangdong (Mon, 11 Dec 2017 03:36:29 GMT):
If I missed some something or if there is a work around, please let me know it.
elie (Mon, 11 Dec 2017 10:43:05 GMT):

baohua (Mon, 11 Dec 2017 14:16:00 GMT):
@wangdong sorry but why we need to implement MSP, u mean those certificate files? They can be generated by cryptogen? Or we can directly using existing on inside the test dir.
david_dornseifer (Mon, 11 Dec 2017 15:54:32 GMT):
@baohua the changelog.sh script is very simple right now and always rewrites the entire CHANGELOG.md file. Will setup an ticket to have a more advanced version
baohua (Tue, 12 Dec 2017 02:46:14 GMT):
thanks, yes i tried, it works well, would be even better if can automatically detect all the release tags.
guolidong (Tue, 12 Dec 2017 06:10:40 GMT):
Has joined the channel.
wangdong (Tue, 12 Dec 2017 15:10:09 GMT):
@baohua because it is related to the channel initializing. After the channel created, to use this channel, the channel instance will have to be got, client.new_channel, client.get_channel, and add orderer to the channel instance and at last initialize this Channel. This channel initialization will get the msp info from orderer. I got an error which says: *Failed to deserialize creator identity, err MSP Org1MSP is unknown*. I think this error is related to the msp.
baohua (Wed, 13 Dec 2017 00:51:29 GMT):
@wangdong can u help create some bug in jira?
baohua (Wed, 13 Dec 2017 00:52:28 GMT):
i think i've met similar issues in some case, there one possible reason is that the msp credential files doesn't match the image version, need to regenerate all the msp credential files using cryptogen
wangdong (Wed, 13 Dec 2017 13:34:48 GMT):
sure. I will have some inspects on this issue before creating the item.

yeah
baohua (Fri, 15 Dec 2017 03:02:51 GMT):
as @grapebaba also suggest

baohua (Fri, 15 Dec 2017 03:03:15 GMT):

wangdong (Fri, 15 Dec 2017 03:03:23 GMT):
reading the test case
grapebaba (Fri, 15 Dec 2017 03:03:28 GMT):
and must at least have a success test for each function
baohua (Fri, 15 Dec 2017 03:03:42 GMT):
:thumbsup:
wangdong (Fri, 15 Dec 2017 03:03:43 GMT):
I think we need the msp
wangdong (Fri, 15 Dec 2017 03:03:52 GMT):
am I right?
baohua (Fri, 15 Dec 2017 03:04:04 GMT):
so can we using existing crypto-config?
baohua (Fri, 15 Dec 2017 03:04:11 GMT):
or do u need to generate new one?
grapebaba (Fri, 15 Dec 2017 03:04:14 GMT):
i think so
grapebaba (Fri, 15 Dec 2017 03:04:40 GMT):
you can use existing crypto-config
baohua (Fri, 15 Dec 2017 03:05:20 GMT):
and feel free to let me know if wanna some new one, i just create one for v1.0.5 yesterday haha
wangdong (Fri, 15 Dec 2017 03:06:07 GMT):
what do you mean by exiting one?
baohua (Fri, 15 Dec 2017 03:06:57 GMT):
`test/fixtures/e2e_cli/crypto-config`
grapebaba (Fri, 15 Dec 2017 03:07:06 GMT):
msp is just a set of key and cert files there
baohua (Fri, 15 Dec 2017 03:07:10 GMT):
it contains 2 peerOrgs and ordererOrg
wangdong (Fri, 15 Dec 2017 03:09:00 GMT):
the config in the docker-compose file?
wangdong (Fri, 15 Dec 2017 03:09:38 GMT):

额 我是不是说中文更方便。。。貌似大佬们都能看得懂
baohua (Fri, 05 Jan 2018 03:00:10 GMT):
code repo里面有些文档可以先看下 @QwertyJack :)
grapebaba (Fri, 05 Jan 2018 03:01:51 GMT):
:raised_hand:
baohua (Fri, 05 Jan 2018 03:01:58 GMT):
ok, will start meeting
baohua (Fri, 05 Jan 2018 03:02:04 GMT):
today's agenda is at https://wiki.hyperledger.org/projects/fabric-sdk-py/meetings/20180105.
baohua (Fri, 05 Jan 2018 03:02:25 GMT):
Mostly, we've done `chaincode install, channel create, integration testing framework refinement`
baohua (Fri, 05 Jan 2018 03:02:43 GMT):
The active ongoing work is for chaincode instantiate/invoke
baohua (Fri, 05 Jan 2018 03:02:50 GMT):
how's going kai
grapebaba (Fri, 05 Jan 2018 03:03:19 GMT):
not ready
baohua (Fri, 05 Jan 2018 03:03:19 GMT):
@grapebaba busy with ur team, aha?
baohua (Fri, 05 Jan 2018 03:03:38 GMT):
hope everything goes well
grapebaba (Fri, 05 Jan 2018 03:03:48 GMT):
let me try next week
baohua (Fri, 05 Jan 2018 03:03:55 GMT):
ok, heard u will visit beijing?
grapebaba (Fri, 05 Jan 2018 03:04:02 GMT):
yeah
baohua (Fri, 05 Jan 2018 03:04:06 GMT):
when is the trip
grapebaba (Fri, 05 Jan 2018 03:04:32 GMT):
plan is 1.26
baohua (Fri, 05 Jan 2018 03:04:41 GMT):
stay for a weekend?
wangdong (Fri, 05 Jan 2018 03:05:06 GMT):
hi
grapebaba (Fri, 05 Jan 2018 03:05:06 GMT):
should be
baohua (Fri, 05 Jan 2018 03:05:08 GMT):
would look forward if u can help introduce the pysdk project in the meetup
grapebaba (Fri, 05 Jan 2018 03:05:27 GMT):
haha
baohua (Fri, 05 Jan 2018 03:05:32 GMT):
sdk is important part of operation, right
baohua (Fri, 05 Jan 2018 03:05:41 GMT):
@wangdong hi, how's going
wangdong (Fri, 05 Jan 2018 03:06:02 GMT):
emm, I am blocked by the msp error.
grapebaba (Fri, 05 Jan 2018 03:06:11 GMT):
let us communicate in wechat @baohua
baohua (Fri, 05 Jan 2018 03:06:17 GMT):
i still believe that python is the 1st choice in operational world
baohua (Fri, 05 Jan 2018 03:06:27 GMT):
@wangdong can u elaborate the problem
grapebaba (Fri, 05 Jan 2018 03:06:29 GMT):
:ok_hand:
baohua (Fri, 05 Jan 2018 03:06:40 GMT):
@grapebaba and i would like to see if can help
grapebaba (Fri, 05 Jan 2018 03:06:50 GMT):
I agree
grapebaba (Fri, 05 Jan 2018 03:07:03 GMT):
for operation python is good
baohua (Fri, 05 Jan 2018 03:07:06 GMT):
right now we are using generated msp path in the code, so what's the problem there?
wangdong (Fri, 05 Jan 2018 03:07:09 GMT):
MSP Org1MSP is unknown
wangdong (Fri, 05 Jan 2018 03:07:30 GMT):
actually I have never touch anything about the msp
wangdong (Fri, 05 Jan 2018 03:07:52 GMT):
It is user id related I think
baohua (Fri, 05 Jan 2018 03:07:54 GMT):
oh, are u using the same 1.0.0 code in fabric
baohua (Fri, 05 Jan 2018 03:08:13 GMT):
hmmm, i guess it might be format problem
baohua (Fri, 05 Jan 2018 03:08:41 GMT):
have u tried the e2e example in fabric 1.0.5?
wangdong (Fri, 05 Jan 2018 03:09:01 GMT):
not yet
baohua (Fri, 05 Jan 2018 03:09:23 GMT):
suggest u try it first. besides, are u in the software park today?
wangdong (Fri, 05 Jan 2018 03:10:35 GMT):
And I wonder if the channel part is enough for the later development of the chaincode operation. Like msp config and channel initialize are not finished? They will affect
wangdong (Fri, 05 Jan 2018 03:10:42 GMT):
No, I am in xi'an now
grapebaba (Fri, 05 Jan 2018 03:12:23 GMT):
I think it is enough @wangdong , let us discuss in wechat or JIRA
wangdong (Fri, 05 Jan 2018 03:12:36 GMT):
I have finished the test code. Error says the channel is not initialized. So I guess these parts will be important too.
wangdong (Fri, 05 Jan 2018 03:12:38 GMT):
OK
baohua (Fri, 05 Jan 2018 03:12:50 GMT):
the whole steps: 1. create a channel; 2. peer joined the channel; 3. peer install chaincode; 4. peer instantiate chaincode; 5. peer invoke chaincode
baohua (Fri, 05 Jan 2018 03:12:59 GMT):
every step can be done by cli or sdk
baohua (Fri, 05 Jan 2018 03:13:33 GMT):
as kai and i suggested, pls have a look at e2e example, and let's discuss offline :)
wangdong (Fri, 05 Jan 2018 03:13:58 GMT):
OK
baohua (Fri, 05 Jan 2018 03:14:09 GMT):
:golf:
baohua (Fri, 05 Jan 2018 03:14:30 GMT):
ok, any other issues to discuss? look forward we can solve the problem next week!
grapebaba (Fri, 05 Jan 2018 03:14:50 GMT):
may we can discuss with audio
baohua (Fri, 05 Jan 2018 03:15:19 GMT):
using zoom?
wangdong (Fri, 05 Jan 2018 03:15:24 GMT):
I am ok
baohua (Fri, 05 Jan 2018 03:15:37 GMT):
sure, let's try in next meeting?
baohua (Fri, 05 Jan 2018 03:16:04 GMT):
@grapebaba can u send an email to tracy to preserve the zoom timeslot for us?
grapebaba (Fri, 05 Jan 2018 03:16:45 GMT):
ok
wangdong (Fri, 05 Jan 2018 03:19:13 GMT):
So shall we call this an end ?
baohua (Fri, 05 Jan 2018 03:19:21 GMT):
ok, any more issue?
grapebaba (Fri, 05 Jan 2018 03:19:28 GMT):
no
wangdong (Fri, 05 Jan 2018 03:19:29 GMT):
no
baohua (Fri, 05 Jan 2018 03:19:33 GMT):
@wangdong ?
baohua (Fri, 05 Jan 2018 03:19:42 GMT):
what's ur meaning of an end?
wangdong (Fri, 05 Jan 2018 03:19:59 GMT):
I mean let's end this meeting :grinning:
baohua (Fri, 05 Jan 2018 03:20:02 GMT):

baohua (Mon, 15 Jan 2018 04:00:33 GMT):
feel free to contribute fix, too: https://github.com/hyperledger/fabric-sdk-py/blob/master/CONTRIBUTING.md
vieiramanoel (Mon, 15 Jan 2018 04:31:42 GMT):
@baohua thnks! I'll test it, any contribution that I can make I'll for sure
vieiramanoel (Mon, 15 Jan 2018 15:18:22 GMT):
@baohua I saw a __init__ inside a module folder, is sdk compatible with python3?
vieiramanoel (Mon, 15 Jan 2018 17:55:08 GMT):
At CAClient construction, i've tried some ways to pass my ca-cert.pem but idk what format are ca_certs_path is waiting
vieiramanoel (Mon, 15 Jan 2018 17:58:18 GMT):
`self.ca_client = CAClient("https://admin:adminpw@ca.goledger.com:7054", ca_certs_path='ca-cert.pem')`
vieiramanoel (Mon, 15 Jan 2018 17:58:40 GMT):
considering that ca-cert.pem is in the same folder that script
vieiramanoel (Mon, 15 Jan 2018 18:02:25 GMT):
i tried absolute path as well
vieiramanoel (Mon, 15 Jan 2018 18:04:00 GMT):
in both cases i get this error
vieiramanoel (Mon, 15 Jan 2018 18:04:00 GMT):
in both cases i get this error when `self.ca_client.get_cainfo()`
vieiramanoel (Mon, 15 Jan 2018 18:04:05 GMT):
```requests.exceptions.SSLError: HTTPSConnectionPool(host='ca.goledger.com', port=7054): Max retries exceeded with url: /api/v1/cainfo (Caused by SSLError(SSLError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:645)'),))```
vieiramanoel (Mon, 15 Jan 2018 18:28:59 GMT):
from `fabric-ca-client` command line I'm able to do this operations
vieiramanoel (Mon, 15 Jan 2018 19:43:49 GMT):
I verified that `get_cainfo()` doesn't implements tls-enabled case, I tried to repeat process made in enroll method to pass ca-cert.pem as verify argument. I got this error then:

@baohua yes, it will be great!

[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=HgZTCjhhnGZRBgFMG) @baohua is a huge problem not using requests library? I can make a post using curl and sending same certfile set in verify and that works

@baohua is a huge problem not using requests library? I can make a post using curl and sending same certfile set in verify and that works
baohua (Wed, 17 Jan 2018 00:43:16 GMT):
aha, if u can make it works with `curl`, then the grammar is very similar with the `request` lib. it's python, very human readable: http://docs.python-requests.org/
baohua (Wed, 17 Jan 2018 01:13:38 GMT):
@wangdong thanks for the work, and seems ci failed: https://gerrit.hyperledger.org/r/#/c/16865/
baohua (Wed, 17 Jan 2018 01:27:22 GMT):
seems we can change `print sth` to `print(sth)`: https://jenkins.hyperledger.org/job/fabric-sdk-py-verify-x86_64/294/console
vieiramanoel (Wed, 17 Jan 2018 02:37:21 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=TsNNh7NxJAiin5BmN) @baohua the problem is when `requests.post(url, cacert)`
vieiramanoel (Wed, 17 Jan 2018 02:37:57 GMT):
Ssl Lib throws a error, but we are studying it yet. Our goal is to make it work with requests
vieiramanoel (Wed, 17 Jan 2018 02:39:39 GMT):
Apparently the problem is with self-signed certificate
vieiramanoel (Wed, 17 Jan 2018 02:40:14 GMT):
Which doesn't belongs to certifi ssl certs list
vieiramanoel (Wed, 17 Jan 2018 02:42:58 GMT):
verify=False doesn't work too
wangdong (Wed, 17 Jan 2018 11:06:43 GMT):
So should building environment in the CI be changed?
wangdong (Wed, 17 Jan 2018 11:06:43 GMT):
I have updated it. It seems something wrong with the environment. I have saw the error.
wangdong (Wed, 17 Jan 2018 11:06:45 GMT):

wangdong (Wed, 17 Jan 2018 11:07:33 GMT):
But it works fine in my Mac.
baohua (Wed, 17 Jan 2018 14:36:25 GMT):
it's because the version of python to use. we should take python3.
vieiramanoel (Wed, 17 Jan 2018 18:26:51 GMT):
https://github.com/requests/requests/issues/4477
vieiramanoel (Wed, 17 Jan 2018 19:24:24 GMT):
@baohua according to [sigmavirus24](https://github.com/sigmavirus24) the requests owner on this [issue](https://github.com/requests/requests/issues/4477#issuecomment-358411993) they can't handle it _magically_ as cURL does. In fact there's some verify errors when your try to connect to fabric-ca through openssl command-line interface
vieiramanoel (Wed, 17 Jan 2018 19:36:21 GMT):
I'll try to get better informations about this in ca channel with smithbk
smithbk (Wed, 17 Jan 2018 20:09:02 GMT):
Has joined the channel.
vieiramanoel (Wed, 17 Jan 2018 21:32:23 GMT):
@baohua I had a hangouts with smithbk from #fabric-ca and him recommended use another lib that doesn't use openssl for tls communication, pycurl apparently does use openssl but it doesn't throw an error about bad_ecc_cert. This occurs cuz the fabric-ca isn't designed to communicate with openssl

@vieiramanoel thanks, and would u like to create a jira issue to report the whole issue context, let's discuss and decide what action we need to take. thanks!
wangdong (Thu, 18 Jan 2018 02:19:07 GMT):
Should the building environment of CI be changed?
vieiramanoel (Thu, 18 Jan 2018 04:11:26 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=FJ3kZBZjTMxZfXPjN) @baohua do I continue explaining what we found out here and we discuss it or open a new issue?
baohua (Thu, 18 Jan 2018 05:15:01 GMT):
thanks, let's discuss there
baohua (Thu, 18 Jan 2018 05:18:55 GMT):

done
baohua (Thu, 18 Jan 2018 05:47:31 GMT):
thanks for the report, we will discuss the issue in tmr meeting.
baohua (Thu, 18 Jan 2018 05:47:35 GMT):
@here Dear all, we will have meeting tmr morning, pls help update the agenda at https://wiki.hyperledger.org/projects/fabric-sdk-py/meetings/20180119, notice we are using a new zoom system, thanks!
vieiramanoel (Thu, 18 Jan 2018 05:56:22 GMT):
I'm still confused about timezones, but I guess I put on my gCalendar the right time haha
vieiramanoel (Thu, 18 Jan 2018 05:56:44 GMT):
We're are far distant in fact

david_dornseifer (Thu, 18 Jan 2018 11:24:01 GMT):
UTC +1
baohua (Thu, 18 Jan 2018 12:18:27 GMT):
got it, david, maybe we should move the meeting to a new time. which is good to u? most other people are at UTC+8.
grapebaba (Thu, 18 Jan 2018 14:36:08 GMT):
@vieiramanoel i checked code and tested, two problem.
grapebaba (Thu, 18 Jan 2018 14:36:51 GMT):
first, the cert file and key file in python SDK is indeed not ECC, I will change it
grapebaba (Thu, 18 Jan 2018 14:37:23 GMT):
second, enroll method works fine with tls enabled
grapebaba (Thu, 18 Jan 2018 14:37:50 GMT):
get ca info method indeed missing ca_cert path arg
grapebaba (Thu, 18 Jan 2018 14:37:58 GMT):
i will change it too
grapebaba (Thu, 18 Jan 2018 14:40:46 GMT):
note you must use your python with new ssl version
grapebaba (Thu, 18 Jan 2018 14:40:46 GMT):
note you must use your python with new openssl version
vieiramanoel (Thu, 18 Jan 2018 17:57:50 GMT):
@grapebaba i updated my openssl to latest version, tried again and got same error
vieiramanoel (Thu, 18 Jan 2018 17:58:10 GMT):
i have acess to my cloud CA, how do I get the ecc certfile?
vieiramanoel (Thu, 18 Jan 2018 17:58:10 GMT):

grapebaba (Fri, 19 Jan 2018 01:43:28 GMT):
how do you deploy fabric network?
grapebaba (Fri, 19 Jan 2018 01:44:00 GMT):
use fabric sample or not?
baohua (Fri, 19 Jan 2018 02:54:41 GMT):
fabric sample is a good reference, we can use it or write our own script, btw we can discuss more in the meeting later, would u like to add a agenda item? @grapebaba https://wiki.hyperledger.org/projects/fabric-sdk-py/meetings/20180119

[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=hA46vPEeFpBHp58iJ) @grapebaba I use the sample as model, changed just the hostnames, orgvariables etc to fit in our project
vieiramanoel (Fri, 19 Jan 2018 17:41:54 GMT):
at fabric-samples it uses the `ca-cert.pem` generated at server init to make tls operations between client and server
vieiramanoel (Fri, 19 Jan 2018 17:42:10 GMT):
I'd like to use this cert file to make operation

I got a problem. When I try to make a channel to join the peer. And it randomly gets the genesis block. Sometime it can get the genesis block, sometimes it can't. I have set up a timeout after the creation of the channel. But it does not improve. And I can make sure the channel is created successfully.

@wangdong strange, can u test with the peer cli? maybe we can add some retry

@david_dornseifer @vieiramanoel hi, what's the free time slots for u guys? now we have developers from utc -2, +1, +8, let’s find a better time slot for the meeting. seems morning time for -2/+1, and evening time for +8 may work
baohua (Sun, 28 Jan 2018 02:06:57 GMT):

I have solved that. I add a timeout in the right place.@baohua

wangdong (Sun, 28 Jan 2018 10:20:11 GMT):
Because even I delete the chaincode, it will raise again.
baohua (Sun, 28 Jan 2018 10:30:41 GMT):
@wangdong according to the error, there should be 4 arguments for the chaincode deployment. i guess u can check the deployment parameters.

it is not

vieiramanoel (Fri, 02 Feb 2018 17:50:34 GMT):
@grapebaba I saw you added `_ca_cert_path` to verify at getcacert, i'd already tried that and still I got verify failed both from openssl and requests
vieiramanoel (Fri, 02 Feb 2018 17:51:13 GMT):
which fabric-ca cert did you use to test it?
vieiramanoel (Fri, 02 Feb 2018 17:51:24 GMT):
the ca-root cert?
vieiramanoel (Fri, 02 Feb 2018 17:51:39 GMT):
neither tls-cert or ca-cert worked for me
vieiramanoel (Fri, 02 Feb 2018 17:55:26 GMT):
Another thing that I figured out was that the response of CA-server for /api/v1/cainfo for requests method is the authorization hash itself not the CaChain
vieiramanoel (Fri, 02 Feb 2018 17:56:07 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=TojZqt7wWT9FRJfEY) If you use `fabric-ca-client getcacerts url` you'll see the difference between the server response

wangdong (Sun, 04 Feb 2018 15:39:38 GMT):
The problems has been addressed.
wangdong (Sun, 04 Feb 2018 15:40:00 GMT):
The chaincode container is not removed after the test.
wangdong (Sun, 04 Feb 2018 15:40:00 GMT):
The chaincode image is not removed after the test.
wangdong (Sun, 04 Feb 2018 15:40:40 GMT):
So everytime as long as the the same version chaincode is test, the same chain code container will be used.
wangdong (Sun, 04 Feb 2018 15:40:40 GMT):
So everytime as long as the the same version chaincode is test, the same chain code container will be started.
wangdong (Sun, 04 Feb 2018 15:41:08 GMT):
@baohua please help to remove the chaincode container.
wangdong (Sun, 04 Feb 2018 15:41:08 GMT):
@baohua please help to remove the chaincode image.
baohua (Mon, 05 Feb 2018 01:42:22 GMT):
will make clean work? @wangdong
baohua (Mon, 05 Feb 2018 01:42:22 GMT):
will `make clean` work? @wangdong
wangdong (Mon, 05 Feb 2018 04:59:39 GMT):
no, each version chaincode will create a responding image, and a container.
wangdong (Mon, 05 Feb 2018 04:59:54 GMT):
And the image will not be remove after the test
wangdong (Mon, 05 Feb 2018 05:00:42 GMT):
that' why once's the chaincode installed, the same error will happen even I changed it.
wangdong (Mon, 05 Feb 2018 05:01:06 GMT):
I think the chaincode image should be remove after the test
wangdong (Mon, 05 Feb 2018 05:01:14 GMT):
@baohua
baohua (Mon, 05 Feb 2018 05:01:50 GMT):
yes, i agree
baohua (Mon, 05 Feb 2018 05:02:27 GMT):
but for the integration testing, it should only be running once
baohua (Mon, 05 Feb 2018 05:02:45 GMT):
to including the full lifecycle operations on channel/chaincode
baohua (Mon, 05 Feb 2018 05:03:12 GMT):
so it should be OK even we do not remove manually?
vieiramanoel (Mon, 05 Feb 2018 05:12:38 GMT):
Byfn should'nt be ok as a fabric network to use python sdk? Better than putting a script on sdk must be just refer to byfn page I think
wangdong (Mon, 05 Feb 2018 05:13:29 GMT):
byfn is using node sdk now
vieiramanoel (Mon, 05 Feb 2018 05:14:45 GMT):
Oh you're right, the chaincode is installed and everything
vieiramanoel (Mon, 05 Feb 2018 05:15:33 GMT):
I always used the step-by-step to bring network up
vieiramanoel (Mon, 05 Feb 2018 05:16:01 GMT):
There's a wiki? I can write this.
vieiramanoel (Mon, 05 Feb 2018 05:16:31 GMT):
Just until the part before joining the channel right?
vieiramanoel (Mon, 05 Feb 2018 05:16:31 GMT):
Just until the part before joining the channel, right?
wangdong (Mon, 05 Feb 2018 05:17:03 GMT):
what kind of wiki you mean??
wangdong (Mon, 05 Feb 2018 05:17:19 GMT):
use py-sdk in byfn?
wangdong (Mon, 05 Feb 2018 05:18:24 GMT):
wiki for BYFN?
vieiramanoel (Mon, 05 Feb 2018 05:18:28 GMT):
The read the docs page, can I just upload a page to there? "Bringing network up with python-sdk"
wangdong (Mon, 05 Feb 2018 05:18:56 GMT):
Of course, it sounds great
vieiramanoel (Mon, 05 Feb 2018 05:19:28 GMT):
Ok! By the morning/afternoon I should check that
wangdong (Mon, 05 Feb 2018 05:20:44 GMT):
I just finished the deploy chaincode, then the invoke and query. Then the fundamental will be done. Hope more and more people will get attention to the py-sdk.
wangdong (Mon, 05 Feb 2018 05:21:36 GMT):
The patch will be pushed soon.
vieiramanoel (Mon, 05 Feb 2018 05:21:53 GMT):
Where do we'd put the docker-compose files?
vieiramanoel (Mon, 05 Feb 2018 05:22:18 GMT):
Doesn't make sense put on sdk code in my opinion
vieiramanoel (Mon, 05 Feb 2018 05:23:15 GMT):
When writing the wiki should refer to byfn folder? What's the better way to do that? Help to figure it out
vieiramanoel (Mon, 05 Feb 2018 05:23:15 GMT):
When writing the wiki, should I refer to byfn folder? What's the better way to do that? Help to figure it out
wangdong (Mon, 05 Feb 2018 05:29:21 GMT):
I think we can do this under py-sdk. maybe a new item under py-sdk. byfn-py? we can make this done and then to see if necessary to combine py and node into byfn. anyway if please go ahead to do this.
wangdong (Mon, 05 Feb 2018 05:30:28 GMT):
@baohua so this behavior is not unexpected?
vieiramanoel (Mon, 05 Feb 2018 05:32:15 GMT):
If you say so I'll submit the page along with the necessary files to run the sample
wangdong (Mon, 05 Feb 2018 05:33:27 GMT):
@baohua But I do not think this is good enough. Because whenever some one runs the test cases there will some unwanted container images in this machine. This is not good. We should at least to remove this kind images at test stage.
wangdong (Mon, 05 Feb 2018 05:35:01 GMT):
@vieiramanoel emm, btw, please open a new item in jira to describe your idea in details. After you finish people will review it.
vieiramanoel (Mon, 05 Feb 2018 05:36:01 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=mLmpFxrZ4ogbCow9M) @wangdong ok!
baohua (Mon, 05 Feb 2018 05:42:36 GMT):
@wangdong i agree!
baohua (Mon, 05 Feb 2018 05:43:27 GMT):
i have used this command to clean the chaincode images, FYI. "docker rmi -f $(docker images |grep 'dev-peer'|awk '{print $3}')".
baohua (Mon, 05 Feb 2018 05:43:47 GMT):
when they are using the default dev net, all images names are started with dev-peer
baohua (Mon, 05 Feb 2018 05:47:25 GMT):
@wangdong look forward to seeing ur pr :)
vieiramanoel (Mon, 05 Feb 2018 05:48:06 GMT):
I think is independent of the net, @baohua. Our composer's chaincode start a dev-peer-* image too
vieiramanoel (Mon, 05 Feb 2018 05:48:06 GMT):

baohua (Mon, 05 Feb 2018 05:48:54 GMT):
@vieiramanoel we can take the byfn example as a good reference. Once the network is started, we can write the tutorial documentation on how to use py sdk to interact with the fabric network
baohua (Mon, 05 Feb 2018 05:49:46 GMT):
besides, the existing integration testing case also show steps to quickly start a network using docker-compose.
baohua (Mon, 05 Feb 2018 05:50:18 GMT):
feel free to summarize some separate steps for that, would expect there can be some documentation quickly.
baohua (Mon, 05 Feb 2018 05:51:14 GMT):
And to the `dev-peer` prefix, it is defined in the peer config `networkId: dev`. by default we can use it to filter out the chaincode images.
vieiramanoel (Mon, 05 Feb 2018 05:53:51 GMT):
I didn't know that 😅
baohua (Mon, 05 Feb 2018 05:54:43 GMT):
aha, it is a good way to learn fabric quickly by developing the sdk
vieiramanoel (Mon, 05 Feb 2018 05:54:55 GMT):
We can use then `docker exec container printenv networkId`
vieiramanoel (Mon, 05 Feb 2018 05:55:07 GMT):
To get this value after all
vieiramanoel (Mon, 05 Feb 2018 05:55:39 GMT):
And add this to make clean line
baohua (Mon, 05 Feb 2018 05:55:41 GMT):
not yet, as it is defined in the config file, not the env variables.
vieiramanoel (Mon, 05 Feb 2018 05:56:05 GMT):
What config file?
baohua (Mon, 05 Feb 2018 05:56:22 GMT):
`core.yaml`, And i've no better idea, but maybe we can start with the workaround
vieiramanoel (Mon, 05 Feb 2018 05:57:28 GMT):
Hmm I'll think about it

wangdong (Mon, 05 Feb 2018 13:38:36 GMT):
@baohua The install chaincode is skipped ? with channel created and joining? But chain code installation does not require a channel.
baohua (Mon, 05 Feb 2018 13:54:33 GMT):
yes, but for a full-lifecycle integration testing, can run `channel creation`, `channel join` and then `chaincode installation`. after that, can extend with more operations.
wangdong (Mon, 05 Feb 2018 14:57:01 GMT):
Then channel should be modified accordingly. So this app channel is the more general than SYSTEM channel? Last time kai discussed with you. I thought you changed this. I really upvote kai's idea. I like this system channel's design. Regarding this life cycle, I do not think this will affect.
baohua (Mon, 05 Feb 2018 15:02:41 GMT):
no, system channel should not be used for chaincode
wangdong (Tue, 06 Feb 2018 01:39:36 GMT):
This is not the system channel of Fabric. Anyway, I fixed it.

Hi Everyone, I've been using the node SDK for fabric to do most of my work so far but the python version would be the mode ideal version. I see that the `eventhub` and some other parts of the SDK are still not complete. Is there a minimal example of querying chaincode using python? When is the pythonSDK expected to be released?
sudheesh001 (Wed, 07 Feb 2018 12:41:27 GMT):

baohua (Wed, 07 Feb 2018 13:18:52 GMT):
@sudheesh001 the code is not finished yet, we expect to release the first release in Q1 2018. btw, welcome to give feedbacks on your usage experience with existing sdks, which will help us to decide the roadmap. thanks!
sudheesh001 (Thu, 08 Feb 2018 03:18:11 GMT):
@baohua Thanks. I am really looking forward to the python SDK. The node SDK has been good and solved the issues for a POC using fabric that we had built, we're now moving to pre-prod and most of our other repositories are in python. For the proof of concept we had hacked up an interface between our python services calling some node endpoints to query or invoke the chaincode. However, we really don't want to do this in prod/pre-prod and want to move to a more elegant python library.
Please do let me know in case there's something I could help on. We're currently blocked by this

baohua (Thu, 08 Feb 2018 03:26:23 GMT):
@sudheesh001 exactly, you can find some info at https://wiki.hyperledger.org/projects/fabric-sdk-py. welcome to attend our meeting (hope the time is good to you)
baohua (Thu, 08 Feb 2018 03:26:39 GMT):
we have done the channel creation/join and chaincode installation.
baohua (Thu, 08 Feb 2018 03:27:01 GMT):
working on other features. welcome to help contribute like fixing bug, implement feature and even documentation :)
sudheesh001 (Thu, 08 Feb 2018 04:34:52 GMT):
@baohua Thanks, so the next meeting is on the 9th i.e. tomorrow at 1PM UTC?
sudheesh001 (Thu, 08 Feb 2018 04:35:35 GMT):
I see from the minutes of the last meeting that there is some work in `invoke` of chaincode that's ongoing. Has that been completed?
baohua (Thu, 08 Feb 2018 04:55:10 GMT):
exactly! the invoke has some code already, but not finished yet.
sudheesh001 (Thu, 08 Feb 2018 05:40:41 GMT):
Oh alright! In the fabric node SDK, the invoke functionality needs the `eventhub` to listen to `TxEventListener` so that the `transactionProposal` can be successful and then sent to the orderer, so if some parts of the `invoke` are already available, does that mean that the `eventhub` part of the SDK has also been written fairly to a stage which is usable?
sudheesh001 (Thu, 08 Feb 2018 05:42:04 GMT):
Also are these parts of the code pushed upstream to github? :)
baohua (Thu, 08 Feb 2018 07:07:15 GMT):
oh, @david_dornseifer was working on the eventhub support, but it's not update for quite a while. Would you like to talk to him?
baohua (Thu, 08 Feb 2018 07:07:19 GMT):
@sudheesh001

Wanted to get my hands dirty with a little low hanging fruit and created JIRA FAB-8155 along with the required patch at https://gerrit.hyperledger.org/r/17721 Would love your review. Looking forward to contributing more
baohua (Fri, 09 Feb 2018 08:29:22 GMT):
@sudheesh001 ci failed, and u can find the log from jenkins links in the comment
baohua (Fri, 09 Feb 2018 08:29:34 GMT):
thanks for your agile fix!
sudheesh001 (Fri, 09 Feb 2018 09:00:27 GMT):
@baohua Thanks, The CI logs show build failed because of a test error in `test_instantiate_chaincode`. However in my patch this file was untouched and shouldn't have caused any of the build failures since it's just a `.gitignore` and `ReadMe` file changes. Would it be possible to retrigger the build for that changes? :) Unless of course I am missing something
baohua (Fri, 09 Feb 2018 09:00:58 GMT):
you can input `recheck` as a comment, that will trigger a rebuilding
sudheesh001 (Fri, 09 Feb 2018 09:05:07 GMT):
Just did that on the `gerrit` changes, waiting for jenkins to restart the build. Is that the right place or did you mean to input `recheck` on JIRA?
baohua (Fri, 09 Feb 2018 09:09:09 GMT):
gerrit is the right place
sudheesh001 (Fri, 09 Feb 2018 09:12:33 GMT):
Great, I've done that, does it generally take time for the build to restart?
baohua (Fri, 09 Feb 2018 09:32:46 GMT):
yes
sudheesh001 (Fri, 09 Feb 2018 10:36:53 GMT):
@baohua Looks like the jenkins build didn't restart after typing in `recheck` as a comment on https://gerrit.hyperledger.org/r/17721 Would it be possible for you to have a look into it and see if I have done the right thing?
baohua (Fri, 09 Feb 2018 12:11:24 GMT):
let me see
baohua (Fri, 09 Feb 2018 12:12:10 GMT):

Received error from server: rpc error: code = Internal desc = transport is closing, ending chaincode stream* 2. *Error starting Simple chaincode: rpc error: code = Internal desc = transport is closing*
When I try to instantiate the chaincode, but it fails to start it with the error above
Is there any one knowing what 's going on ?
some thing wrong with the RPC connection
?

It seems that peer just ends the stream to the chain code container

Thanks @baohua Looking forward to sending in more
sudheesh001 (Mon, 12 Feb 2018 09:22:46 GMT):
I just realized that the `protos/google/protobuf` having `timestamp` and `empty` are not available in the `python-sdk` however they are needed for the `client-utils` and `block_decoder` which are in turn needed for eventhub, Is there an existing JIRA for this? Should I open one and send in a patch?
baohua (Mon, 12 Feb 2018 10:40:01 GMT):
sure, go ahead, btw we are using fabric 1.0.0 now~
sudheesh001 (Mon, 12 Feb 2018 11:05:27 GMT):
Sure @baohua Commit https://gerrit.hyperledger.org/r/#/c/17785/ open for review for JIRA-8215
sudheesh001 (Mon, 12 Feb 2018 11:05:44 GMT):
Its currently running the jenkins CI build
sudheesh001 (Mon, 12 Feb 2018 11:13:58 GMT):
Jenkins seems to have succeeded: https://jenkins.hyperledger.org/job/fabric-sdk-py-verify-x86_64/333/
baohua (Mon, 12 Feb 2018 11:46:27 GMT):
in fabric 1.0.0, there is no such two proto files? When are they introduced?
sudheesh001 (Mon, 12 Feb 2018 11:58:12 GMT):
It looks like the files were checked into `fabric-sdk-node` last year January, maybe before the 1.0.0 release.
sudheesh001 (Mon, 12 Feb 2018 11:58:53 GMT):
maybe this needs a more of a fix in `node-SDK` than the addition to `py-sdk`
sudheesh001 (Mon, 12 Feb 2018 11:59:13 GMT):
what do you say @baohua
sudheesh001 (Mon, 12 Feb 2018 12:01:04 GMT):
The files I was talking about are here https://github.com/hyperledger/fabric-sdk-node/tree/fd853302541b2e6e24f7e0440fc9ebfb746fa829/fabric-client/lib/protos/google/protobuf
sudheesh001 (Mon, 12 Feb 2018 12:01:14 GMT):
this was the commit they were introduced in
baohua (Mon, 12 Feb 2018 12:03:21 GMT):
so it's not from fabric code.
baohua (Mon, 12 Feb 2018 12:03:33 GMT):
do u know the reason of using them?
sudheesh001 (Mon, 12 Feb 2018 12:04:38 GMT):
Node seems to be building the current timestamp using this
```
/*
* This function will create a timestamp from the current time
*/
module.exports.buildCurrentTimestamp = function() {
var now = new Date();
var timestamp = new _timestampProto.Timestamp();
timestamp.setSeconds(now.getTime() / 1000);
timestamp.setNanos((now.getTime() % 1000) * 1000000);
return timestamp;
};
```
sudheesh001 (Mon, 12 Feb 2018 12:05:22 GMT):
and looks like the emptyProto isn't being used anywhere.
baohua (Mon, 12 Feb 2018 12:07:07 GMT):
yes, that's why i asked, we should make sure it's necessary for the py sdk. you know, the node and python grammar somehow is different.
sudheesh001 (Mon, 12 Feb 2018 12:08:06 GMT):
Agreed, should we use the golang sdk as a reference instead?
sudheesh001 (Mon, 12 Feb 2018 12:12:18 GMT):
@baohua Is the node's `installChaincode` implemented in `python` as `send_install_proposal`?
baohua (Mon, 12 Feb 2018 12:12:49 GMT):
yes, the golang based gohfc is more similar with python grammar
baohua (Mon, 12 Feb 2018 12:13:43 GMT):
have a look at `https://github.com/hyperledger/fabric-sdk-py/tree/master/test/integration`, which gives some example. And i'm refining the API soon, to make it more user-friendly.
sudheesh001 (Mon, 12 Feb 2018 12:18:30 GMT):
Sure, I'll use that as a reference for now to implement parts of the `eventhub`
sudheesh001 (Mon, 12 Feb 2018 12:18:45 GMT):
however the nodeSDK has this line
` chaincodeDeploymentSpec.setEffectiveDate(clientUtils.buildCurrentTimestamp()); //TODO may wish to add this as a request setting`
baohua (Mon, 12 Feb 2018 12:19:24 GMT):
`https://github.com/CognitionFoundry/gohfc`
sudheesh001 (Mon, 12 Feb 2018 12:19:25 GMT):
I think it's still a work in progress for which they're using `buildCurrentTimeStamp()` and `timestamp.proto`, would it be possible for someone from the #fabric-sdk-node channel to help?
baohua (Mon, 12 Feb 2018 12:19:51 GMT):
ok, feel free to ask in that channel
sudheesh001 (Mon, 12 Feb 2018 12:21:02 GMT):
Is https://github.com/hyperledger/fabric-sdk-go not the latest golang SDK? Should I use the one you've pointed to here [ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=ZvaHveHfHYyPZyJPp) @baohua
baohua (Mon, 12 Feb 2018 12:22:05 GMT):
for fabric 1.0.0 the gohfc one is good enough, you can also have a look at the node one. but remember we should implement in the pythonic style
baohua (Mon, 12 Feb 2018 12:22:26 GMT):
that is `efficient but user-friendly`
sudheesh001 (Mon, 12 Feb 2018 12:23:01 GMT):
agreed however I think there are a lot of things we can learn from node, but mocking their style may not be the wisest thing to do.

agree!

sudheesh001 (Tue, 13 Feb 2018 06:03:17 GMT):
@baohua , @apurvmehra and I have been trying to write the `eventhub.py` by taking both the `gohfc` and `node-sdk` as a reference, however the two implementations are drastically different and that's causing some confusion. While the `node-sdk` depends on other methods from `Remote.js`, `Client-Utils` and `Config.js`. From what we understand these also depend on the `BlockDecoder`. We were wondering if @david_dornseifer had implemented some part of it from which we could continue or do we need to start from scratch? Would it be possible to have a call sometime over Zoom/jitisi/hangouts to discuss more regarding this?
baohua (Tue, 13 Feb 2018 06:17:19 GMT):
as far as i know, there's no much implementation yet, so you need to design from scratch. Yes, a block decoder can be a good start point actually.
sudheesh001 (Tue, 13 Feb 2018 06:47:34 GMT):
Okay great, we'll continue to work with the blockDecoder. In case we get stuck somewhere it'd be great if we could have a short conversation over a call.

@baohua We were working on the block_decoder using the node as reference since golang doesn't have this. Is there a reason why the golang SDK doesn't have the block decoder? We have an initial version but isn't complete and have quite a few queries, should we send in a review and then keep updating it?
baohua (Thu, 22 Feb 2018 13:51:41 GMT):
yes, feel free to submit a pr.
baohua (Thu, 22 Feb 2018 13:51:56 GMT):
do not know why go sdk doesn't have that func.
sudheesh001 (Thu, 22 Feb 2018 13:51:59 GMT):
The javascript version mentions `.decode()` and `.toBuffer()` methods. If I take an instance of `common_pb2` in python all the `bytes` fields in `proto` become `str` right?
grapebaba (Thu, 22 Feb 2018 13:58:11 GMT):
@sudheesh001 we had two similar methods in util.py
sudheesh001 (Thu, 22 Feb 2018 14:08:59 GMT):
@grapebaba , @baohua Here's an initial version which is quite hacky https://gerrit.hyperledger.org/r/18199 I put in a bunch of `TODO` where I was stuck.
sudheesh001 (Thu, 22 Feb 2018 14:10:21 GMT):
basically I didn't understand the `decode()` and `toBuffer()` methods
baohua (Thu, 22 Feb 2018 14:11:26 GMT):
i guess @grapebaba is still in vacation.
sudheesh001 (Thu, 22 Feb 2018 14:11:40 GMT):
From what I understand, the block decoder class has methods that help convert the `proto` and their requivalent python objects from `*_pb2` to required python objects
baohua (Thu, 22 Feb 2018 14:11:41 GMT):
basically, it's related to json serialization.
sudheesh001 (Thu, 22 Feb 2018 14:11:55 GMT):
oh, sorry to disturb `grapebaba`
baohua (Thu, 22 Feb 2018 14:12:10 GMT):
i would like to suggest you read some docs on manipulating json and serialization in node.js.
baohua (Thu, 22 Feb 2018 14:12:33 GMT):
the methods are different in python, but similar functionality.
sudheesh001 (Thu, 22 Feb 2018 14:13:16 GMT):
Yeah in `python` we generally use `.dumps()` and `loads()` for the json serialization and deserialization, maybe even have `__todict__()` methods
sudheesh001 (Thu, 22 Feb 2018 14:14:21 GMT):
Sure, I wouldn't mind doing the reading on the json serialization and deserialization. I generally use `json-serialize` as the npm library for most of my serialization and deserialization tasks or use `JSON.stringify()`, Is the `decode()` method similar?
sudheesh001 (Thu, 22 Feb 2018 14:17:32 GMT):
It looks like the method inside `utils.py` only is a failsafe method for non-unicode characters to be decoded into `utf-8` right?
```
def proto_str(x):
return proto_b(x).decode("utf-8")
```
sudheesh001 (Thu, 22 Feb 2018 14:33:20 GMT):
@baohua I need to send an update to the change 18199, Should I do git review -d 18199 for this to send a patch to the pull request?
baohua (Thu, 22 Feb 2018 14:34:30 GMT):
you can have a look at hfc/fabric/client.py, inside it used SerializeToString()
baohua (Thu, 22 Feb 2018 14:35:01 GMT):

@grapebaba Please use https://gerrit.hyperledger.org/r/#/c/18201/ patch for inital round of review, @baohua The CI fails because of lint warnings from flake8 as I included some proto which haven't been used yet but need to be used later.

sudheesh001 (Fri, 23 Feb 2018 06:07:46 GMT):
I had a small question, for testing the blockdecoder, I need to read the file contents of the genesis block and then decode it right? Should I use the contents inside `fixtures/e2e_cli/channel_artifacts/orderer.genesis.block` for the tests? When I read this file into a variable called `data` all I receive is
```
>>> data
'\n"'
```
sudheesh001 (Fri, 23 Feb 2018 06:07:53 GMT):
Am I doing something wrong here?
sudheesh001 (Fri, 23 Feb 2018 06:11:19 GMT):
I have also tried using the same file they use for testing blockdecoder in node i.e. https://github.com/hyperledger/fabric-sdk-node/blob/release/test/fixtures/channel/twoorgs.genesis.block
sudheesh001 (Fri, 23 Feb 2018 06:16:24 GMT):

apurvmehra (Tue, 27 Feb 2018 07:59:30 GMT):
I was working on decoding the metadata section for block_decoder. The order.genesis.block that we currently use to write the test case does not have any content for the metadata section, should I create a new block for the test case or do we have another block with meta data already ? Thanks
baohua (Tue, 27 Feb 2018 09:02:37 GMT):
@apurvmehra i guess u can help write some method (e.g., encode_block) to encode out a block first.
sudheesh001 (Tue, 27 Feb 2018 11:30:08 GMT):
@baohua I agree that we could write a method called `encode_block()` and encode all the contents from the string of the `Block()` object to a binary block file. However, for now it'd be really nice if there are some files that already contain metadata for the same so that we could test
sudheesh001 (Tue, 27 Feb 2018 11:31:12 GMT):
Maybe we can implement `encode_block()` sometime this week, Should we just use random data like `this is a signature` for `bytes signature = 1` for example?
baohua (Wed, 28 Feb 2018 00:35:48 GMT):
i guess it should be fine. an if you wanna find some existed block, here are examples: https://github.com/yeasy/docker-compose-files/blob/master/hyperledger_fabric/v1.0.5/kafka/channel-artifacts/businesschannel_4.block
sudheesh001 (Wed, 28 Feb 2018 06:27:01 GMT):

MuhammadSalah (Sun, 04 Mar 2018 12:50:03 GMT):
Greetings everybody, can somebody help me connect the python sdk to HL?
MuhammadSalah (Sun, 04 Mar 2018 12:50:23 GMT):
I have installed a virtual env; with all support and Hyperledger from pip upgraded.
MuhammadSalah (Sun, 04 Mar 2018 12:50:49 GMT):
I have an up and running network, and I want to connect to the orderer using the python client.
MuhammadSalah (Sun, 04 Mar 2018 12:51:08 GMT):
However, the github documentation is very brief, and I already have TLS, and credentials.
MuhammadSalah (Sun, 04 Mar 2018 12:52:14 GMT):
I mean the crypto-config material, any help is appreciated. Thank you.
grapebaba (Sun, 04 Mar 2018 12:56:29 GMT):
@MuhammadSalah you can view the test in e2e dir
grapebaba (Sun, 04 Mar 2018 12:56:42 GMT):
such as crea
MuhammadSalah (Sun, 04 Mar 2018 12:57:03 GMT):
Ok I am cloning the repo
MuhammadSalah (Sun, 04 Mar 2018 12:57:31 GMT):
Which file sir?
MuhammadSalah (Sun, 04 Mar 2018 13:00:26 GMT):
I pretty much did the same on the function_test.py
MuhammadSalah (Sun, 04 Mar 2018 13:00:28 GMT):
@grapebaba
MuhammadSalah (Sun, 04 Mar 2018 13:00:57 GMT):
Question is, now I have TLS should not I pass the certificate to the client?
MuhammadSalah (Sun, 04 Mar 2018 13:02:14 GMT):
I get pumped with this:
requests.exceptions.ConnectionError: ('Connection aborted.', BadStatusLine('\x00\x00\x00\x04\x00\x00\x00\x00\x00\x00\x00\x04\x08\x00\x00\x00\x00\x00\x00\x0e\xff\xf1',))
MuhammadSalah (Sun, 04 Mar 2018 13:06:29 GMT):
I am running a network version 1.0.5 and I initiate my client with this api version tls=True, and the usual base url for the orderer.
MuhammadSalah (Sun, 04 Mar 2018 13:08:19 GMT):
I should run some of the tls right?
MuhammadSalah (Sun, 04 Mar 2018 13:08:26 GMT):
configure_client?
MuhammadSalah (Sun, 04 Mar 2018 13:08:37 GMT):
I think I have got it through code. @grapebaba Thank you.
grapebaba (Sun, 04 Mar 2018 13:09:25 GMT):
👌
grapebaba (Sun, 04 Mar 2018 13:09:49 GMT):
feel free post any other question
MuhammadSalah (Sun, 04 Mar 2018 13:11:09 GMT):
Thank you :)
I will try to give it a shot.
See what pops up.
MuhammadSalah (Sun, 04 Mar 2018 13:19:58 GMT):
Maybe please which are client certs and ca cert are needed?
MuhammadSalah (Sun, 04 Mar 2018 13:20:14 GMT):
Which file paths should I be providing through the crypto-config?
MuhammadSalah (Sun, 04 Mar 2018 13:20:21 GMT):
I guess I got things mixed up a little.

any clue of this?
sudheesh001 (Mon, 05 Mar 2018 08:59:33 GMT):
@wangdong Looks like a networking issue between the machines/containers... something is making the connections/requests drop
wangdong (Mon, 05 Mar 2018 09:33:08 GMT):
yes, I am not sure what exactly problem is
wangdong (Mon, 05 Mar 2018 09:33:22 GMT):
maybe the network?
wangdong (Mon, 05 Mar 2018 09:33:58 GMT):
i previously thought it is the default policy but it is not
sudheesh001 (Tue, 06 Mar 2018 05:54:06 GMT):
@grapebaba and @baohua Please review https://gerrit.hyperledger.org/r/#/c/18769/ Looks like a small issue in modules for further work on blockdecoder's `HeaderType` and their required methods for KV RW Decode methods
baohua (Tue, 06 Mar 2018 07:26:57 GMT):
+2！
sudheesh001 (Tue, 06 Mar 2018 07:39:03 GMT):
@baohua and @apurvmehra Thank you for the review. Looking forward to seeing it merged so that I can continue on the other parts
baohua (Tue, 06 Mar 2018 07:52:54 GMT):
u do not need to wait the merge to continue the work. git has a feature of "rebase"

sudheesh001 (Thu, 08 Mar 2018 10:42:43 GMT):
@baohua , @grapebaba and others in the maintainers #fabric-sdk-node channel. The current way in which we use and include proto files in the respective SDKs seems to make files slowly inconsistent. I came across one of the issues recently for this where the `mspconfig.proto` file in the py sdk directory is older than the one in the master branch for the Node SDK.
sudheesh001 (Thu, 08 Mar 2018 10:43:28 GMT):
Wouldn't it be nicer to have a single repository and include these files as `git submodules`, that'd keep the codebases consistent and make all SDKs have the same proto files.

There's a work in progress for improving the blockdecoder to have the headertypes and KV read write sets here https://gerrit.hyperledger.org/r/#/c/18877/ Of course, I still need to fix the lint issues and add tests. I'll do that today and maybe we'll have a nice change request before the meeting

@asish0512 what is your question then?
asish0512 (Sun, 11 Mar 2018 04:09:24 GMT):
@wangdong I tried to setup the dev environment as instructed in the README and the tests failed. There is a bug and needs to be fixed
asish0512 (Sun, 11 Mar 2018 04:09:47 GMT):
Also I am trying to fix it

baohua (Mon, 12 Mar 2018 01:35:42 GMT):
@wangdong @sudheesh001 for the 2nd problem, it seems related to the timezone. we should specify hardly to use UTC to avoid mistakes.
sudheesh001 (Mon, 12 Mar 2018 04:00:54 GMT):
@wangdong @baohua Thanks, I'll take a look at that timestamp issue. I could reproduce that on Windows too so it definitely needs a fix
sudheesh001 (Mon, 12 Mar 2018 04:01:25 GMT):
In the meanwhile, I think this looks good with your reviews, Could it be merged please so that I can rebase my WIP change request and send an update? https://gerrit.hyperledger.org/r/#/c/18871/

@baohua Can https://gerrit.hyperledger.org/r/#/c/18871/ be merged please? I am currently writing tests for the block decoder and parts of it fail because of these updates which are on a different branch locally
sudheesh001 (Mon, 12 Mar 2018 07:55:11 GMT):
I've merged the branches locally for continuing the tests but the change request will continue to break on jenkins if this is the case
baohua (Mon, 12 Mar 2018 07:56:44 GMT):
we need at least two +2 for each merge, @grapebaba and @david_dornseifer could you help review when free?

so quick catch! @grapebaba. it's merged now @sudheesh001

My patch firstly ran well in local, but not good in CI. But now this new issue arise after I installed python3.6. But when I uninstalled python3.6, this still arise. Not sure how this issue takes place.
baohua (Tue, 13 Mar 2018 01:37:56 GMT):
@sudheesh001 sure, feel free to add that. Sorry i thought it's well known rule :)
baohua (Tue, 13 Mar 2018 01:38:30 GMT):
@wangdong can u check if the state_dict has the element? python 2.7 and 3.6 should both support the grammar
baohua (Tue, 13 Mar 2018 01:39:16 GMT):
And maybe you can do some `make clean`. oh, and manually delete the local keystore path.
wangdong (Tue, 13 Mar 2018 02:20:48 GMT):
The 'make clean' does not work.
baohua (Tue, 13 Mar 2018 04:24:57 GMT):
manually delete the local keystore path?

@baohua yes, when I delete the hfc-kvs in /tmp and it works
wangdong (Wed, 14 Mar 2018 08:42:12 GMT):
BTW, why the patch work in my mac, but not on the CI.
wangdong (Wed, 14 Mar 2018 15:18:25 GMT):
And it also works well in my ubuntu
wangdong (Wed, 14 Mar 2018 15:19:14 GMT):

not much from me, I will send chaincode invocation after this one.
sudheesh001 (Thu, 15 Mar 2018 04:38:35 GMT):
From a end usability perspective, I think having the user do something like this for the chaincode could be a good idea. I am open to your thoughts on the same.
```
request_params = {
'chaincode_id': 'mycc',
'fcn': 'DoSomething',
'args': ['this','is','a','list','of','args']
}
# To get UserContext from .hfckeystore
client.get_user_context(username, certs, etc..,)
# If the chaincode is of a query/GetState type
client.query_chaincode(request_params, user_context) # Returns Transaction response
# If the chaincode is of a invoke/PutState type
client.invoke_chaincode(request_params, user_context) # Returns Transaction response
# While installing chaincode
client.install_chaincode('INSTALL', {'name_of_chaincode', 'version', 'path' ... other params })
client.install_chaincode('INSTANTIATE', {contents....})
client.install_chaincode('UPGRADE', {contents...})
```

Maybe we should spend some time on writing a few tutorials on what we currently have.

Hi guys, I'm new to this channel. I'm a big fan of Hyperledger Fabric. As I'm a python developer, hope `fabric-sdk-py` will be one of my favorite tool. So, I'm eager to learn and contribute to developing the tool. I just need some direction such as where and how to start.
sudheesh001 (Thu, 15 Mar 2018 08:46:00 GMT):
Hi @mohammadjh Absolutely! Welcome here, A good place would be to start with the python SDK repository. Did you set up the repository from gerrit?
mohammadjh (Thu, 15 Mar 2018 08:48:20 GMT):
@sudheesh001 Thanks for your response. Not yet, but hope I will do it today.
sudheesh001 (Thu, 15 Mar 2018 08:49:27 GMT):
You can then find the existing list of issues of `fabric-sdk-py` component in JIRA from the following filtered link. https://jira.hyperledger.org/issues/?jql=project%20%3D%20FAB%20AND%20resolution%20%3D%20Unresolved%20AND%20component%20%3D%20fabric-sdk-py%20ORDER%20BY%20priority%20DESC%2C%20updated%20DESC
mohammadjh (Thu, 15 Mar 2018 08:57:13 GMT):
Thanks I will check the list after setup the repository from gerrit.
sudheesh001 (Thu, 15 Mar 2018 09:02:01 GMT):
Asking everyone on the channel, I just opened an issue FAB-8880, Should we consider doing something like this for improving the dev requirements?
sudheesh001 (Thu, 15 Mar 2018 09:02:45 GMT):
https://jira.hyperledger.org/browse/FAB-8880

wangdong (Thu, 15 Mar 2018 12:27:03 GMT):
@sudheesh001 what is the difference from the current one? I think we already have one.
baohua (Thu, 15 Mar 2018 13:13:28 GMT):
@wangdong pls check my previous comments on https://gerrit.hyperledger.org/r/#/c/19149/. Should response on the questions.
baohua (Thu, 15 Mar 2018 13:37:14 GMT):
Dear all, we will cancel the project meeting this week, feel free to have discussions offline if needed, enjoy the weekend! Thanks!
wangdong (Thu, 15 Mar 2018 15:40:16 GMT):
yes. I have replied. As I have said the api will be done later after invoke which is already ok. I will send it out for review once this is merged.
wangdong (Thu, 15 Mar 2018 15:40:21 GMT):

sudheesh001 (Thu, 15 Mar 2018 17:38:18 GMT):
@wangdong `autopep8` can be as a developers command line utility which can be used to automatically format the python files so that they pass our `flake8` tests. It's an easy way to fix the problem than manually fixing the `flake8` errors and warnings one by one.
wangdong (Fri, 16 Mar 2018 00:28:39 GMT):
it sounds nice
baohua (Fri, 16 Mar 2018 01:11:03 GMT):
@wangdong and the commit msg format (And update to: [FAB-8777] Fix chaincode instantiation bug), let me help fix for u.
wangdong (Fri, 16 Mar 2018 01:14:51 GMT):
OK. Thanks.

I got a 5 seconds timeout in my Mac, but 20 in CI always fails
baohua (Sun, 18 Mar 2018 08:26:28 GMT):
@wangdong the ci logs is here, seems grammar error: https://jenkins.hyperledger.org/job/fabric-sdk-py-verify-x86_64/386/console
wangdong (Sun, 18 Mar 2018 09:59:29 GMT):
that's because the observer instance is not ready. But It works well in my Mac even for a 5 seconds time out.
baohua (Sun, 18 Mar 2018 10:02:40 GMT):
suspect diff python version in CI?
baohua (Sun, 18 Mar 2018 10:02:43 GMT):

wangdong (Sun, 18 Mar 2018 10:04:56 GMT):
OK. Thanks very much.

baohua (Sun, 18 Mar 2018 11:06:03 GMT):
@david_dornseifer would u like to give ur opinion on https://gerrit.hyperledger.org/r/#/c/19349/ to add a new maintainer? Thanks!
wangdong (Sun, 18 Mar 2018 14:14:36 GMT):
yes, I think it may be the difference between of the python version.
wangdong (Sun, 18 Mar 2018 14:15:11 GMT):
I got python 36 in Mac, but the CI seems got python 35.
wangdong (Sun, 18 Mar 2018 14:15:19 GMT):
not sure
wangdong (Sun, 18 Mar 2018 14:18:06 GMT):
The invoke works pretty well in my Mac.
baohua (Mon, 19 Mar 2018 01:25:05 GMT):
@wangdong could you add both py35 or py36 in the tox env and run test under these two engine? If that is the cause, then it should be easy to find how to make the code compatible with either version.
wangdong (Mon, 19 Mar 2018 01:27:14 GMT):
ok
wangdong (Mon, 19 Mar 2018 01:27:20 GMT):
I will try that
wangdong (Mon, 19 Mar 2018 03:12:50 GMT):
OK. I got the root cause. There are two chain code file. The CI and my Mac execute different file.
wangdong (Mon, 19 Mar 2018 03:13:19 GMT):
So I want to ask why two chain code file there?
wangdong (Mon, 19 Mar 2018 04:17:43 GMT):
there are two chain code files. I think this is the problem. If you can delete the chain code container in CI, let's try it again. I got that in my python 3.5.2 env.
wangdong (Mon, 19 Mar 2018 04:17:49 GMT):
@baohua
baohua (Mon, 19 Mar 2018 04:21:06 GMT):
what's ur meaning of "two chaincode files"? every test in ci starts with a clean env?
baohua (Mon, 19 Mar 2018 04:21:06 GMT):
what's ur meaning of "two chaincode files"? The test in ci starts with a clean env, and every operation will follow our script/code.
david_dornseifer (Mon, 19 Mar 2018 07:55:29 GMT):
@baohua I agree, Dong is doing a very good job supporting the sdk development right now +2 :)
baohua (Mon, 19 Mar 2018 09:16:30 GMT):
Congrats @wangdong as new maintainer of the project: https://gerrit.hyperledger.org/r/#/c/19349/! Wish will help the project more!
wangdong (Mon, 19 Mar 2018 09:21:26 GMT):
thanks @baohua
wangdong (Mon, 19 Mar 2018 09:21:48 GMT):

Hi there, I recently came to know about the hypeledger internship programme and I was looking to participate. I know I'm late but I would love to work on this project. I have experience with python and open source development but I'm a novice when it comes to blockchain. I've recently become interested in blockchain and want to learn more about it.

Regarding the internship project, I did a git grep in the repo and saw a lot of stub functions having `pass` in them. I am assuming these are the only parts of the Fabric API that have not been implemented and the students are expected to work on implementing these functionality during the internship programme? Correct me if I'm wrong or missing something.

Besides, another problem I met is that I am using conda to manage environment and pyenv is not compatible with conda 4.4.10. So I cant do `make check` with python3.6 and I am still looking for some workaround to this.
baohua (Mon, 26 Mar 2018 07:22:32 GMT):
u mean the commit msg in local? if you want to merge two commits into one, just use the git's squash support.

is it possible to specify the UTC tz when comparing two timestamps?
dexhunter (Tue, 10 Apr 2018 10:07:47 GMT):
It is possible, but I think we should use utc when parsing the datetime. So I changed `datetime.fromtimestamp` to `datetime.utcfromtimestamp` but I seems to get the same error @wangdong indicates (aka timeout is not enough to invoke)
Any updates on the reasons why it needs more time for the event to complete? Thanks!

wangdong (Tue, 10 Apr 2018 13:07:38 GMT):
@dexhunter do you want to help?
wangdong (Tue, 10 Apr 2018 13:07:54 GMT):
that's good news

@sudheesh001 sudheesh, would you like to take this work? https://jira.hyperledger.org/browse/FAB-6702
dexhunter (Wed, 11 Apr 2018 06:22:31 GMT):

Yes, I am still working on this.
dexhunter (Wed, 11 Apr 2018 06:22:31 GMT):

Yes, I am still working on this. Edit: Hmm.. okay, it seems that your 20427 has fixed the problem. https://gerrit.hyperledger.org/r/#/c/20427/
dexhunter (Wed, 11 Apr 2018 06:24:43 GMT):
> @dexhunter do you want to help?
Yep, I also applied for the summer internship. Whether I will be admitted or not, I would like to help finishing the python sdk.
baohua (Wed, 11 Apr 2018 06:42:42 GMT):
ok, pls help review this change: https://gerrit.hyperledger.org/r/#/c/20427/
wangdong (Wed, 11 Apr 2018 06:51:04 GMT):
I think this resolved the time zone issue, right?

Hi Folks , I am an Phd Candidate in www.nitrr.ac.in my Linkedind Profile is https://www.linkedin.com/in/eramitg/ for sake of earning an Phd Degree i was proposed Blockchain Technology research work area to my guide so oom I request all of you gyus ,please guide me and assign me some research oriented task so that we mutullay benifited research related to Hyperledger Umbrella Project , All of you feel free to catch me on twitter or skype to https://twitter.com/eramitg1 or amitg.iitb skype id also in Zoom to in Zoom ID 3649222703 or whatsapp +917773011100 Regards
sudheesh001 (Thu, 12 Apr 2018 02:50:25 GMT):
@eramitg Welcome, there are quite a few number of research problems in blockchains in general that are not specific to hyperledger projects. Some of the problems are
- Correctness and security proofs
- Scaling and performance
- Confidentiality
- Authenticated data feeds
- Safety and compliance
- Interledger communication
A good place to start reading good research work is the work done at the `Intitiative for cryptocurrencies and contracts` from Cornell University.
baohua (Thu, 12 Apr 2018 03:01:58 GMT):
sure, @sudheesh001 feel free to pick it as very related to your decoding contributions.
sudheesh001 (Thu, 12 Apr 2018 03:02:46 GMT):
Absolutely, I am currently running on some strict deadlines at work and will be able to help further once that's complete

I was referring to this problem. Why adding more time would work?
dexhunter (Thu, 12 Apr 2018 13:26:28 GMT):
> I add more time to sleep, and it works.
> This async mechanism seems not so stable.
I was referring to this problem. I was wondering why adding more time would work?
baohua (Thu, 12 Apr 2018 14:01:24 GMT):
@wangdong may give some hints
eramitg (Thu, 12 Apr 2018 16:10:57 GMT):
@sudheesh001 thanks for suggestion to read this problem from Cornell ,but reading from diffrent University would be no much as compare to work with Hyperledger community with their specific problems for research poin of view..
sudheesh001 (Thu, 12 Apr 2018 16:28:51 GMT):
The problems I described above and as indicated by Cornell's initc3 group are the same problems faced by different hyperledger projects. So the theoretical understanding of those is what's necessary to ensure that you can have significant research contributions to the engineering projects under the hyperledger umbrella. Please also take your time to read the paper on Fabric https://arxiv.org/pdf/1801.10228.pdf
wangdong (Fri, 13 Apr 2018 01:13:22 GMT):
@dexhunter this is an async issue I think. when the request is sent to the fabric network, you have to wait for some time to get the response.
wangdong (Fri, 13 Apr 2018 01:15:24 GMT):
And it efficiency may be affected by other facts, like version or OS. Because in my Mac and I the cloud VM 5 sec is fine. But it does not work in CI.
wangdong (Fri, 13 Apr 2018 01:15:36 GMT):
So I think it is not stable
wangdong (Fri, 13 Apr 2018 01:16:14 GMT):
So we intend to use the async/await mechanism later.
wangdong (Fri, 13 Apr 2018 01:16:58 GMT):
This is the new and original feature of the Python, which is supported after 3.4
wangdong (Fri, 13 Apr 2018 01:21:34 GMT):
BTW Last time you said you can help with the query task, https://jira.hyperledger.org/browse/FAB-9215 this is the tasks.
wangdong (Fri, 13 Apr 2018 01:22:36 GMT):
The pattern is simple, and you can figure it out easily I think. If any problem just ask
wangdong (Fri, 13 Apr 2018 01:23:20 GMT):
https://gerrit.hyperledger.org/r/#/c/20141/
wangdong (Fri, 13 Apr 2018 01:23:52 GMT):
this is the one I have completed with out test case. And you can start here to add a test case for this
wangdong (Fri, 13 Apr 2018 01:26:23 GMT):
And help to refine the code meanwhile.
sudheesh001 (Fri, 13 Apr 2018 02:54:14 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=A74o4A2McCybueHjc) @baohua This looks interesting, However there seem to be failing test cases for chaincode invocation and most of them seem to be from an object called `_Rendezvous`. Are these timeout issues happening on the CI?
baohua (Fri, 13 Apr 2018 03:27:22 GMT):
yeap, still try to figure out what happens....
baohua (Fri, 13 Apr 2018 03:34:32 GMT):
i noticed that when do the cc instantiate, peer reports some error: `go: error while loading shared libraries: /lib/x86_64-linux-gnu/libpthread.so.0: invalid ELF header`
baohua (Fri, 13 Apr 2018 05:34:58 GMT):
fixed: https://gerrit.hyperledger.org/r/#/c/20439/
wangdong (Fri, 13 Apr 2018 06:25:22 GMT):
@baohua I am not clear about the change in network config.
baohua (Fri, 13 Apr 2018 06:25:43 GMT):
the current config has wrong path to the credential files.
baohua (Fri, 13 Apr 2018 06:25:49 GMT):
which is fixed in this patchset
wangdong (Fri, 13 Apr 2018 07:02:23 GMT):
I mean the change: grpcs://localhost:7054 to localhost:7054
wangdong (Fri, 13 Apr 2018 07:03:59 GMT):
I will review the patch thoroughly later on
baohua (Fri, 13 Apr 2018 07:31:33 GMT):
with the grpcs prefix, the connection cannot be established.
wangdong (Fri, 13 Apr 2018 08:45:03 GMT):
then what about the previous test result, are they good?
baohua (Fri, 13 Apr 2018 09:12:02 GMT):
in previous results, they do not use this part in the config
baohua (Fri, 13 Apr 2018 09:12:32 GMT):
the part of config is only used in my new added test cases (i.e., the new channel join API)

I am trying to help some new guy to address this issue
sudheesh001 (Wed, 18 Apr 2018 03:53:30 GMT):
Do we plan to support python2? I thought we were only building for python3+
wangdong (Wed, 18 Apr 2018 04:00:07 GMT):
I think we still support py2, right?
wangdong (Wed, 18 Apr 2018 04:00:28 GMT):
Or just abandon py2 from now?
wangdong (Wed, 18 Apr 2018 04:00:35 GMT):
@baohua
baohua (Wed, 18 Apr 2018 04:20:52 GMT):
i think we need to focus on py3.x

@Sushilpaneru feel free to discuss here on the issue
Sushilpaneru (Mon, 23 Apr 2018 05:16:47 GMT):
for fab-9497, do we write a wrapper that directly uses configtxgen binary or do we have some kind of API that we can use?
Sushilpaneru (Mon, 23 Apr 2018 05:17:02 GMT):
@baohua
baohua (Mon, 23 Apr 2018 05:21:13 GMT):
for the 1st step, we can wrap configtxgen, and futhermore, we can abandon the configtxgen usage by generating the required transaction code in python all.
baohua (Mon, 23 Apr 2018 05:21:37 GMT):
FAB-9497
Sushilpaneru (Mon, 23 Apr 2018 05:34:32 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=B4NwAXuQQyNn84CGu) @baohua channel_create() -> calls some kind of
generate() which calls configtxgen with the name of profile in configtx.yaml file. is this workflow okay?
baohua (Mon, 23 Apr 2018 05:34:51 GMT):
sure!
Sushilpaneru (Mon, 23 Apr 2018 05:36:23 GMT):
so the channel_create will have following arguments channel_create(self, orderer_name, channel_name, requester, configtx, profile). is this fine?
Sushilpaneru (Mon, 23 Apr 2018 05:50:46 GMT):
@baohua
baohua (Mon, 23 Apr 2018 05:51:47 GMT):
in this case, do we still need the `configtx` param?
Sushilpaneru (Mon, 23 Apr 2018 06:17:22 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=PoSKewjbydNHEHmPy) @baohua configtx is path to config yaml file.
Sushilpaneru (Mon, 23 Apr 2018 06:17:38 GMT):
we also have assumption that configtxgen binary is in PATH. will this be a valid assumption?
baohua (Mon, 23 Apr 2018 06:18:26 GMT):
OK, then please use `config_yaml` instead of `configtx`. Others, LGTM.
baohua (Mon, 23 Apr 2018 06:18:56 GMT):
thanks for the work!
Sushilpaneru (Mon, 23 Apr 2018 06:19:14 GMT):
Thanks for the help. I will assign the task to me
Sushilpaneru (Tue, 24 Apr 2018 18:54:58 GMT):
@baohua Please review: https://gerrit.hyperledger.org/r/#/c/20977/
wangdong (Wed, 25 Apr 2018 01:28:03 GMT):
@Sushilpaneru CI failed， please have a look at it.
baohua (Wed, 25 Apr 2018 13:12:35 GMT):
@here we will cancel this week's meeting due to the labor day holidays, let's discuss offline and enjoy the holidays. thanks!
Sushilpaneru (Thu, 26 Apr 2018 18:44:42 GMT):
Please Review https://gerrit.hyperledger.org/r/#/c/20977/
Sushilpaneru (Thu, 26 Apr 2018 19:01:23 GMT):
CI failed because configtxgen location doesn't seem to be in PATH variable.
baohua (Thu, 26 Apr 2018 21:57:23 GMT):
@Sushilpaneru then maybe we should install it in some setup script?
Sushilpaneru (Fri, 27 Apr 2018 05:42:09 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=BLWGA67kx9KYE2q92) @baohua will liik into it

wangdong (Sat, 28 Apr 2018 01:22:33 GMT):
BTW, you can always find the error info in https://jenkins.hyperledger.org/job/fabric-sdk-py-verify-x86_64/440/console
Sushilpaneru (Sat, 28 Apr 2018 14:30:00 GMT):
Review again: https://gerrit.hyperledger.org/r/#/c/20977/ . Since CI was failing because configtxgen was not in path, I added a script file for setup process assuming CI runs in venv enviroment
wangdong (Sun, 29 Apr 2018 03:40:23 GMT):
@Sushilpaneru Your failure is because of trailing space which is not good format.

@wangdong thaks for the reply, if I understand correctly, I have to add in the dependency `libcurl4-openssl-dev` which is not a pip dependency. Do you know in which file I could add this for the build to run? Thanks
GuillaumeCisco (Mon, 30 Apr 2018 10:12:36 GMT):
@wangdong thanks for the reply, if I understand correctly, I have to add in the dependency `libcurl4-openssl-dev` which is not a pip dependency. Do you know in which file I could add this for the build to run? Thanks
GuillaumeCisco (Mon, 30 Apr 2018 10:21:35 GMT):
Should it be in image `hyperledger/fabric-baseos:x86_64-0.3.1` ?
Sushilpaneru (Mon, 30 Apr 2018 13:52:31 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=BDEXGXWWiJhHCxzxd) @wangdong I do that everytime but I get notified error from block_decoder_test.py only. I have removed the trailing whitespaces. CI failed again, it seems CI doesn't run test cases from venv.
Sushilpaneru (Mon, 30 Apr 2018 13:53:53 GMT):
aren't user supposed to use the sdk from venv?
wangdong (Tue, 01 May 2018 01:07:30 GMT):
@GuillaumeCisco what does that package do?
wangdong (Tue, 01 May 2018 01:16:56 GMT):
@Sushilpaneru do you mean the virtual environment? this is the not always the case. I run sdk in my machine, not venv. Actually it is your choice. Anyway I don't think the error is environment related, venv or bare metal. Maybe the py version issue. But we will only support py3.x later. So please make sure your py3.0 environment is good.
wangdong (Tue, 01 May 2018 01:25:13 GMT):
@GuillaumeCisco are you going to install the configtxgen pacakge?
Sushilpaneru (Tue, 01 May 2018 17:26:17 GMT):
@baohua with no failures. https://gerrit.hyperledger.org/r/#/c/21257/
wangdong (Wed, 02 May 2018 04:52:55 GMT):
@Sushilpaneru I reviewed your patch and got one question.
wangdong (Wed, 02 May 2018 04:56:42 GMT):
Is the channel config file output to the hfc/fabric/? I think this is not proper, could you change it to some other dir? Let's keep the code dir clean.
Sushilpaneru (Wed, 02 May 2018 05:20:06 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=nzY3MWBnZ43yvNmR8) @wangdong yes, as a proof of concept I chose the same path for config file. How about we store it in /tmp directory or delete it after the function call is done?
wangdong (Wed, 02 May 2018 05:25:20 GMT):
it is better to store it in /tmp.
GuillaumeCisco (Wed, 02 May 2018 13:09:09 GMT):
@wangdong, If I understand correctly I could fix the issue of installing `pycurl`, if `libcurl4-openssl-dev` is installed before. I do not plan to install configtxgen package.
wangdong (Wed, 02 May 2018 13:20:30 GMT):
Sorry I have not used pycurl. The error results from trailing spaces. as long you can remove them.
wangdong (Wed, 02 May 2018 13:20:36 GMT):
@GuillaumeCisco
GuillaumeCisco (Wed, 02 May 2018 13:25:24 GMT):
@wangdong I think you are mixing my issue with @Sushilpaneru's issue, I did not commit modifications in `create_venv.sh` with trailing spaces
GuillaumeCisco (Wed, 02 May 2018 13:26:49 GMT):
What I'd like to know is where I can add `libcurl4-openssl-dev` for installation for the docker in the CI can install correctly `pycurl`
wangdong (Wed, 02 May 2018 13:28:37 GMT):
you problem is some requirements are missed
wangdong (Wed, 02 May 2018 13:28:49 GMT):
Sorry I missed it.
GuillaumeCisco (Wed, 02 May 2018 13:28:57 GMT):
yes it is
GuillaumeCisco (Wed, 02 May 2018 13:29:37 GMT):
But I don't know where to put `libcurl4-openssl-dev`. And I'm not even sure it will fix the problem for installing pycurl in the `requirements.txt`
wangdong (Wed, 02 May 2018 13:30:58 GMT):
if it is the problem of requirements, then you do not have to install it in docker.
wangdong (Wed, 02 May 2018 13:31:37 GMT):
You should install all the requirements on your development environment.
GuillaumeCisco (Wed, 02 May 2018 13:31:44 GMT):
yes I did it
wangdong (Wed, 02 May 2018 13:32:03 GMT):
pip install -r requirement.txt
GuillaumeCisco (Wed, 02 May 2018 13:32:22 GMT):
I can install `libcurl4-openssl-dev` with `sudo apt install libcurl4-openssl-dev` and then on my machine `pycurl` installs correctly with `pip install - requirements.txt`
GuillaumeCisco (Wed, 02 May 2018 13:32:22 GMT):
I can install `libcurl4-openssl-dev` with `sudo apt install libcurl4-openssl-dev` and then on my machine `pycurl` installs correctly with `pip install -r requirements.txt`
wangdong (Wed, 02 May 2018 13:32:49 GMT):
and requirement-test.txt.
GuillaumeCisco (Wed, 02 May 2018 13:33:41 GMT):
problem is the environment where the `requirements.txt` is installed, I have to tell the CI to first install `libcurl4-openssl-dev`
wangdong (Wed, 02 May 2018 13:39:14 GMT):
CI?
GuillaumeCisco (Wed, 02 May 2018 13:39:27 GMT):
where jenkins launch the testing
wangdong (Wed, 02 May 2018 13:39:38 GMT):
I have no idea about this.
wangdong (Wed, 02 May 2018 13:39:55 GMT):

Sushilpaneru (Tue, 15 May 2018 06:08:01 GMT):
After chaincode invocation, I deserialized the response to ProposalResponse message; ProposaResponse.payload to ProposalResponsePayload; ProposalResponsePayload.extension to ChaincodeAction. Now I'm confused to what message should I deserialize ChaincodeAction.Response.payload ?

GuillaumeCisco (Fri, 01 Jun 2018 08:02:16 GMT):
I had the same issue as you @slimandslam and solved it, by simply running `pip3 install grpcio>= 1.0.1`
GuillaumeCisco (Fri, 01 Jun 2018 08:03:06 GMT):
in my custom docker I beforehand run:
```
RUN apt-get install -y python3-dev python3-setuptools python3-pip
RUN pip3 install --upgrade pip
```
Hope it will help

@slimandslam I think it's about python version. After you `pip3 install grpcio` it's indicating you installed for python2.7. I think you need to use python3 as default interpreter

@slimandslam I think it's about python version. After you `pip3 install grpcio` it's indicating you installed for python2.7. I think you need to use python3 as default interpreter. Or you can just use a virtualenv, something like `virtualenv --system-site-packages -p python3 targetDirectory # for Python 3.n`

I did check nodejs sdk. But they also have a request and check the payload of the response, however, I am not sure if there are an existing function to do such operation in sdk-py or I need to write one from scratch?
baohua (Wed, 13 Jun 2018 01:58:20 GMT):
@dexhunter pls have a look at https://github.com/CognitionFoundry/gohfc and https://github.com/hyperledger/fabric-sdk-go, whose grammar is more close to Python. And pls read the existing documentation and have a quick explore of the code structure first. Btw, we will have the meeting this week, feel free to bring up your questions.

A problem with invoke is that I have to instantiate the cc in the same function (I tried to just send a tx_propsal but it will return cc not exist error) because `send_transaction(orderers, tran_req, tx_context, scheduler=None)` requires `tran_req` which is built from response of instantiation. Besides, I wonder if anyone knows a workaround for the problem or any suggestions? Thanks!

@dexhunter i guess it's not creating channel but just get a handler of the channel. i agree can rename to get_channel.
baohua (Mon, 09 Jul 2018 13:09:26 GMT):
not quite follow the question of `send_transaction`.
dexhunter (Mon, 09 Jul 2018 13:28:20 GMT):
@baohua thanks, I'll take the liberty to rename it. The question is related to `invoke`. The problem is even after I instantiated the cc from the previous function, if I do not instantiate the cc in the same function with invoke, it will return the cc does not exist error. Besides, my local `make check` passed while jenkins build fails at the instantiate step. I guess it was caused by reactive programming since the error indicates the queue is empty. Although I am taking a deeper look at reactive programming, if anyone knows how to fix it, please help, so we can make the process faster. Thanks!

dexhunter (Wed, 18 Jul 2018 14:02:53 GMT):
Hi! I have a question regarding to `invoke`. In the docs
> The CLI invokes chaincode by sending a transaction proposal to a peer. The peer will execute the chaincode and send the endorsed proposal response (or error) to the CLI.
But in the current test code, I saw that we can only send the tx proposal of invoke after a cc proposal (such as instantiate). (To be more detailed: `tran_req` needs `res` which is returned by `send_instantiate_proposal`) When I try to send the tx proposal of invoke first and build tx from it, I got `TypeError: '_Rendezvous' object does not support indexing` error. So it seems the response of just sending tx proposal of invoke does not work. Does anyone knows what might caused the problem? Thanks!
dexhunter (Wed, 18 Jul 2018 18:43:32 GMT):
I also added query installed chaincodes from client at the new patchset https://gerrit.hyperledger.org/r/#/c/24219/
baohua (Thu, 19 Jul 2018 01:08:50 GMT):
@dexhunter invoke/instantiate means: 1) send a Signedproposal to peer, and get response 2)create Envelope based on the response and send to orderer. Would suggest you remove the react mode and check the response first. the status code should be 200 (means OK)
baohua (Thu, 19 Jul 2018 01:09:47 GMT):
+2, thanks!
dexhunter (Thu, 19 Jul 2018 03:56:54 GMT):
@baohua Thank you for the reply. I wonder what are the active subjects in the sentence? If I am not misunderstanding, 1) the client (who is the requestor) sends a Signedproposal to peer and gets response 2) The peers ( the channel ) create an Envelope and send to the orderer
> Would suggest you remove the react mode and check the response first.
I was wondering to do that as well. But there are some logics I am still trying to figure out so I haven't started since it seems I need to rewrite a bunch of functions.

@ilamparithi10 Hi! What's the arguments you used for creating and joining the channel? (A screenshot might be helpful) Besides, the py-sdk is not ready for production yet.

ilamparithi10 (Thu, 19 Jul 2018 09:27:53 GMT):
@dexhunter it returns true . but while a peer joining the channel, my code response = cli.channel_join(

@dexhunter I have tried about retrieving all the channels but the response is empty dict only.
dexhunter (Thu, 19 Jul 2018 09:55:59 GMT):
I am guessing the problem is related to the cache of docker images. I also experienced the same problem when closing the docker and reopening to create a channel with the same name. But after I changed the channel name it worked.

When i create a multiple channel and i run cli._channels it shows only the last created channel. I don't know why?
dexhunter (Thu, 19 Jul 2018 10:14:19 GMT):
the `cli._channels` is `dict` so it probably won't overwrite the previous channels.

unless you overwrite the channel name
ilamparithi10 (Thu, 19 Jul 2018 10:14:55 GMT):

ilamparithi10 (Thu, 19 Jul 2018 10:21:28 GMT):

@ilamparithi10 that means your propose config update transaction contains an old version of refered config. i.e., someone else might have changed that config before u send the change.

Hi fabric-python folks -- I'm curious if anyone has an update on the status of the `eventhub` for the py-sdk and what the future plan might be with the newer event listener methods introduced in v1.1. I'd be interested in jumping in to help wherever it is needed. Cheers
tian (Tue, 21 Aug 2018 08:18:38 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=TjFkkqjpJmbDkQqpC) @tylerwince `eventhub` will be removed in the future, and sdks will suggest end user to use `Event Service` rather than `eventhub`. The detail you can find from here: https://jira.hyperledger.org/browse/FAB-11122
tylerwince (Tue, 21 Aug 2018 13:53:19 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=rsRRywt9hc6fsSpnB) @tian Thanks @tian. I have been following the removal of the eventhub rather closely as it was removed from the go-sdk (the sdk we use primarily) but was asking more specifically about the implementation of the event service api in the python sdk and the status of it's build out

@wangdong Hi! I checked the response from a query. So the result is a tuple with structure looks like .
I was wondering why there are multiple `ProposalResponse`? (The result seems to be identical)

I am not sure. maybe related to your args?
wangdong (Tue, 28 Aug 2018 11:49:59 GMT):
what args did you have for the query? I may need to read some code.
dexhunter (Tue, 28 Aug 2018 12:53:24 GMT):
I don't give any args since I am just query installed chaincodes (you can check this one: https://github.com/hyperledger/fabric-sdk-py/blob/master/test/integration/query_test.py#L127)

dexhunter (Tue, 28 Aug 2018 13:27:01 GMT):
I guess it's related to peers/channel but haven't found where it's defined yet.
tylerwince (Tue, 28 Aug 2018 14:00:46 GMT):
@dexhunter I assume you are passing in a `tx_context` instance and the peers you want to connect to in a `list`? There aren't any default values for those args and are needed for the query
dexhunter (Tue, 28 Aug 2018 15:05:16 GMT):
> @dexhunter I assume you are passing in a `tx_context` instance and the peers you want to connect to in a `list`?
Yes, those are created at the client API. There is no need to specify args for `query_channels` or `query_isntalled_chaincodes` which is the same in other sdks (you only need to know which peer to send tx proposal). My problem is that I don't quite understand why there are multiple identical response, I guess they are caused by different channels/peers. But I need to verify it.

I updated tutorials/tests as well. Free feel to check them as well.
dexhunter (Tue, 28 Aug 2018 23:37:36 GMT):
For `query_block_by_hash` the problem is that in node sdk it gives a separate `argbytes` in the request, but in sdk-py `TXProposalRequest` has no `argbytes`. So I append the `block_hash` to `args`. However, it seems not reading the hash properly. It returns error: entry not found. I am taking a deeper look on this, but if anyone knows what's the problem, please help. Thanks.
baohua (Wed, 29 Aug 2018 07:41:34 GMT):
@dexhunter +2!
baohua (Wed, 29 Aug 2018 07:41:51 GMT):
entry not found, maybe the block doesn't exist yet?
dexhunter (Wed, 29 Aug 2018 07:48:26 GMT):
@baohua But the block hash is returned by the ChainInfo, how could it not exist?
baohua (Wed, 29 Aug 2018 07:57:15 GMT):
oh, i would suggest we verify the hash value first, to check whether it's correct or not
dexhunter (Wed, 29 Aug 2018 09:11:38 GMT):
Yes, I think you are right. The block hash from query_block and query_info seems to be different. But how do I verify the hash value?
dexhunter (Wed, 29 Aug 2018 09:35:55 GMT):
It seems that the previous_hash from both query_block or query_info are the same, while the current_hash is different.
dexhunter (Wed, 29 Aug 2018 09:35:55 GMT):
It seems that the previous_hash from both query_block or query_info are the same, while the current_hash is different.

Ok, I fixed it
dexhunter (Wed, 29 Aug 2018 09:52:45 GMT):
The problem is the format, we need to provide binary format and do not hexlify the bytes to utf-8.

Does anyone know how to fix compatibility of configtxgen 1.2 and 1.0? Is it just caused by configtx.yaml?
tylerwince (Fri, 31 Aug 2018 14:26:23 GMT):
@dexhunter We just recently upgraded to 1.2 and had to revamp our `configtx.yaml` to support 1.2. Which `e2e_cli/` version are you using? We modeled ours off the example config from the `release-1.2` branch
tylerwince (Fri, 31 Aug 2018 14:27:12 GMT):
Also, we noticed some issues with the older `configtxgen` binary. Maybe check to ensure you have removed the old binary and replace it with the ones from that same 1.2 branch
dexhunter (Fri, 31 Aug 2018 16:14:27 GMT):
@tylerwince Hi! I am using version 1.2 but the configtx.yml in fabric-sdk-py is still 1.0.0 (without capabilities). I am not sure the error is caused by the incompability of configtxgen or something else is wrong? What do you think based on the error?
dexhunter (Fri, 31 Aug 2018 16:15:27 GMT):
Screenshot from 2018-09-01 00-15-07.png
dexhunter (Fri, 31 Aug 2018 16:20:22 GMT):
I also noticed there are some minor differences with the configtx.yaml in fabric-samples (https://github.com/hyperledger/fabric-samples/blob/release-1.2/first-network/configtx.yaml) such as `V1_1: Ture` or the order of the config
tylerwince (Fri, 31 Aug 2018 20:13:51 GMT):
@dexhunter looks like you are referencing the OrdererDefaults config before it is declared. I would rearrange your config to match the order of the new configtx in the release-1.2 branch and you do need to add the additional capabilities section you mentioned.
dexhunter (Sat, 01 Sep 2018 08:41:17 GMT):
Okay, after I updated the configtx.yaml file, the configtxgen error was gone. But the server returns new error. `Error processing updated config: Error deserializing key Capabilities for group /Channel/Application: Unexpected key Capabilities`

dexhunter (Sat, 01 Sep 2018 09:00:59 GMT):

baohua (Mon, 03 Sep 2018 02:16:00 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=F8ZsAG3AQBYFXuuqe) @dexhunter capabilities field is introduced since fabric 1.1.
dexhunter (Mon, 03 Sep 2018 13:20:25 GMT):
@baohua Thanks for the info. There is a problem with cc instantiate, it couldn't find the `github.com/example_cc`. It might related to my own environment config, I am trying to debug now.
baohua (Tue, 04 Sep 2018 06:25:46 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=TKBxJDBKujHbofHWP) @dexhunter Noticed that fabric will find chaincode under its $GOPATH, in integration, we set customized $GOPATH in setup step.
dexhunter (Tue, 04 Sep 2018 06:43:38 GMT):
@baohua You are right. The path configuration in my case is wrong.
dexhunter (Tue, 04 Sep 2018 06:44:31 GMT):
Another problem is that I have no problem joining peers from `org1.example.com` but couldn't join peers from `org2.example.com`, I'll try to have a look at that after the previous fix.

@baohua @grapebaba Hi! I just found that FABP-162 fix is not merged, was wondering why? Should I fix it again the most recent change or something else? https://gerrit.hyperledger.org/r/#/c/25944/
dexhunter (Thu, 06 Sep 2018 17:11:02 GMT):
@baohua You are right. The problem is configtx.yaml. After I downgraded configtx.yaml, all tests passed.

dexhunter (Mon, 10 Sep 2018 07:14:10 GMT):
@ilamparithi10 Hi, currently it's under review. I think after @grapebaba viewed, we can release. Although there are not much changed at the new patchset. You can start checking. However, we only support fabric 1.0.x network right now. So if you need features of 1.x, you might want to use other sdk first

Hi everyone
I'm getting started with fabric-sdk-py and following the readme, but I'm getting lots of this same error when running `make check` or `make test`:
```sh
IOError: [Errno Cannot deserialize the user] unsupported pickle protocol: 3
```
any ideas what is this? I'm setting up the virtualenv with `make env` and activating it before testing, so I guess something like that shouldn't happen.

I just solved it, the `make venv` was defaulting to python 2.6 on my machine. How about we change the Makefile to explicitly target python3 when creating the vitual environment?

I think we discussed it long ago. It will make the code more readable and easy to maintain. Most importantly it is the python feature we will not need the third party lib to implement async, like rx and queue.

in the E2E example there are a few different query types (block, transaction / hash, id), but is there a direct way to get the world state, or the latest state of a key?
dexhunter (Sun, 30 Sep 2018 13:00:00 GMT):
@lucaspar Hi! What do you mean by `the wrold state`? Could you give an example?
lucaspar (Sun, 30 Sep 2018 15:06:35 GMT):
@dexhunter absolutely, by world state (aka current state) I mean the glossary definition: https://hyperledger-fabric.readthedocs.io/en/release-1.2/glossary.html#world-state
for example, let's say we have a simple transaction ledger.
With the queries in the E2E example I can easily access a specific block or transaction. But what if I want the total amount of an account?
In the chaincode that seems pretty straightforward with a "stub.GetState()" call, but how is it translated to the fabric-sdk-py to call it from my python application?
I hope I made myself clear :)

Just want to share a problem I met and the solutions, when I use `make check` the virtualenv created by `tox` could not load because it could not open the binary of python3.6 under `.tox/pylint/bin`. and the solution is to add the lib path of system python3.6 to the `LD_LIBRARY_PATH` or config the `/etc/lib.so.conf`. The solution is found at stackoverflow: https://stackoverflow.com/questions/43333207/python-error-while-loading-shared-libraries-libpython3-4m-so-1-0-cannot-open/43623903
dexhunter (Sat, 13 Oct 2018 04:19:03 GMT):
I think I should also update the content of these `.yaml` files but I am sure where the original ones from? `fabric-samples`?
dexhunter (Sat, 13 Oct 2018 06:07:30 GMT):
When we generate protobuf python files why not use `protoc --proto_path=hfc/protos --python_out=hfc/protos --grpc_python_out=hfc/protos hfc/protos/**/*.proto` to specify the path of proto files (which is the current fabric source file do, since the import is relative) but we need to manually add `hfc/protos` to the import? It seems making less sense to me but both method would require extra effort. So I am sticking to the previous one to manually add `hfc/proto` to `*.proto` files but just noted there we could save time in future to change to relative import.

dexhunter (Sat, 13 Oct 2018 21:52:40 GMT):
To a small step first, I just added some config generation scripts https://gerrit.hyperledger.org/r/#/c/26980/ but still need to check why the sdk broke after the protos, crypto-config and artifacts update
dexhunter (Sat, 13 Oct 2018 21:57:48 GMT):

i tried search the history and couldn't find anything that is specific to my problem. I'm using the Python SDK for the first time and I'm connecting to an existing network -- meaning i have the crypto setup for the network and the users and i have public/private keys. On trying to create a channel it looks like the client.py channel_create method is calling generate_channel_tx. generate_channel_tx is trying to re-run configtxgen. This may be correct for setting up a new network but it is blocking me from connecting to a creating a channel for an existing network. Perhaps i have this wrong. Any information that can point me in the right direction would be helpful.
lsher1 (Wed, 17 Oct 2018 22:02:40 GMT):
it *think* i fixed the problem by not using Client.channel_create, instead manually instantiating a Channel object and manually assigning within the channel dict of the Client, but i've run into a new issue while trying to invoke a transaction on the chain.

baohua (Thu, 18 Oct 2018 02:13:07 GMT):
@dexhunter has more accurate number, and expected within several weeks.
lsher1 (Thu, 18 Oct 2018 02:36:26 GMT):
ok thank you. just found out that my crypto was generated with configtxgen 1.1.0 and running against 1.3.0 fabric .... do think this would be problematic?
dexhunter (Thu, 18 Oct 2018 12:53:46 GMT):
@lsher1 yes, I think you need to stick with the version 1.0.x of fabric
dexhunter (Thu, 18 Oct 2018 15:31:30 GMT):
Hmm... it seems that the `<>/tls/server.crt` or `server.key` has been renamed to `<>/tls/client.crt` and `<>/tls/client.key`

@dexhunter you got too much changes in one single patch.
wangdong (Sun, 21 Oct 2018 01:00:04 GMT):
We'd better make it small and readable for each one.
dexhunter (Sun, 21 Oct 2018 06:13:18 GMT):
@wangdong yep, actually I still left room for next patchset ( tutorial & etc.). The large size is caused by the protobuf and artifacts.

By the way, I am still unclear about how to generate businesschannel_4.block (I suppose it is created by decoding a bussinesschannel_4.json with configtxgen) I checked your docker-compose-files repo multiple times but still couldn't find the corresponding generation script ( the kafka example seems to be created without the script) Would you please provide some extra guidance on the issue? Many thanks! @baohua

Hi! I'm new to the fabric-sdk-py, I've been using the client for node, When using enroll for the CAClient, a parameter csr is required to enroll, but this is different from the node client one since it's not required to enroll an admin/user, is there a reason for this? Also there is a CAService enroll and a CAClient.enroll, what is the difference? Thank you for your attention! :-)

Hi, we are currently running into an issue when invoking chaincode that is trying to write transient data. When we invoke without transient data, it works. But when we have transient data, the transaction endorsement fails due to a hash mismatch. Has anyone else encountered this issue?
dexhunter (Mon, 29 Oct 2018 03:18:18 GMT):
@smeyers Hi! Thank you for the report. I will check the issue. But I am not sure when I can finish since I am in midterm exam this week. So if you are in a hurry, please just use without transient data. If you can wait for a while, then I will get back to you before the end of this week. Thanks again.

Hi!
I've been following the tutorial on fabric-sdk-py at https://github.com/hyperledger/fabric-sdk-py/blob/master/docs/tutorial.md.
To enroll an admin, the tutorial says that we need to pass their name and password. However, I am receiving an error saying that 'csr' argument is missing. Am I missing something?
dexhunter (Mon, 29 Oct 2018 08:18:54 GMT):
@AbhinayB Are you using fabric-ca?

It throws me the error: _TypeError: enroll() missing 1 required positional argument: 'csr'_
dexhunter (Mon, 29 Oct 2018 08:48:02 GMT):

[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=gFFkPYzWHDjdE3bf6) @dexhunter Thank you for your immediate reply! Is there a workaround for this? For example, can I use the REST APIs to connect to a CA server in my python code?
dexhunter (Mon, 29 Oct 2018 08:57:52 GMT):
@AbhinayB Yes, I guess so but I haven't really tested.
dexhunter (Mon, 29 Oct 2018 08:58:59 GMT):
But then you really don't have to use python sdk? Maybe it's easier to use node or go first?

dexhunter (Mon, 29 Oct 2018 09:03:34 GMT):
I guess you can use `requests` to do the connections? I am not really familiar with fabric-ca yet. Could you ask at #fabric-ca ? Or let me check the docs

Hello @baohua, following what we talked about yesterday in the meeting, I just checked once again the tutorial from `fabric-sdk-py`. I have a lot of obseravations I wrote in a google doc. I will paste it here.
Fiurthermore, if you could redirect me to the specifications of how to build the SDK, it would be great, I'd like to write the `register` method, which is really important.

Fabric-sdk-py tutorial observations
In the client the CA are not initialized: https://github.com/hyperledger/fabric-sdk-py/blob/master/hfc/fabric/client.py#L103
Following the tutorial https://github.com/hyperledger/fabric-sdk-py/blob/master/docs/tutorial.md#11-load-connection-profile
cli.CAs # ca nodes in the network will give an empty dict
https://github.com/hyperledger/fabric-sdk-py/blob/master/docs/tutorial.md#121-if-no-valid-user-exist-yet-register-and-enroll-from-fabric-ca tutorial is wrong for connecting to server CA. Port should be 7054 too as 7050 is default for ordering services. http or https must be added too.
Change cli = CAClient(server_addr="127.0.0.1:7050")
to cli = CAClient(target="https://127.0.0.1:7054")
admin = cli.enroll(username="admin", password="pass") cannot work as the signature of the method is: def enroll(self, enrollment_id, enrollment_secret, csr):
You need to write admin = cli.enroll("admin", "pass").
However there is another enroll method described in the CAService object:
def enroll(self, enrollment_id, enrollment_secret):
It will generate the csr automatically.
You can write:
from hfc.fabric_ca.caservice import CAService
cli = CAService(target="https://127.0.0.1:7054")
admin = cli.enroll("admin", "pass")
But it will fail with:
requests.exceptions.SSLError: HTTPSConnectionPool(host='127.0.0.1', port=7054): Max retries exceeded with url: /api/v1/enroll (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1051)')))
Looking at the log of your server certificate authority using: docker logs -f rca-org1. You will see:
http: TLS handshake error from 172.18.0.1:33054: remote error: tls: unknown certificate authority
We need to pass the correct certificate:
from hfc.fabric_ca.caservice import CAService
cli = CAService(target="https:/127.0.0.1:7054", ca_certs_path='path_to_my/ca-cert.pem') # do not give tls-ca-cert.pem file, make sure your tls-ca-cert.pem file does not override your ca-cert.pem in your fabric-ca-server.yaml configuration.
admin = cli.enroll("admin", "pass")
You are now able to enroll an user.
You can verify or get your cert.pem file with:
cli._ca_client.get_cainfo()
But you will need to pass the ca_name otherwise an error will be raised:
ValueError: get_cainfo failed with errors []
You can make a full test with:
from hfc.fabric_ca.caservice import CAService
cli = CAService(target="https://127.0.0.1:7054", ca_certs_path='path_to_my/ca-cert.pem', ca_name='rca-org1')
admin = cli.enroll("admin", "pass")
with open('path_to_my/ca-cert.pem', 'rb') as f:
cert = f.read()
print(cli._ca_client.get_cainfo() == cert)
Finally the register method is not yet implemented.

GuillaumeCisco (Fri, 18 Jan 2019 14:29:29 GMT):
I'm facing an issue right now for getting the value of the private key after an enrollment.
When enrolling, a private_key is created like `private_key = self._crypto.generate_private_key()` it give us a `cryptography.hazmat.backends.openssl.ec._EllipticCurvePrivateKey` object.
Does someone know how to get the value of this private key?
GuillaumeCisco (Fri, 18 Jan 2019 14:32:03 GMT):
As i can understand the private key is created with this library: https://cryptography.io/en/latest/hazmat/primitives/asymmetric/ec/#cryptography.hazmat.primitives.asymmetric.ec.generate_private_key
GuillaumeCisco (Fri, 18 Jan 2019 14:42:50 GMT):
Only thing I can find is key dumping here: https://cryptography.io/en/latest/hazmat/primitives/asymmetric/serialization/?highlight=dump#key-dumping
But I do not know how to dump with ec :/

my god, why don't we have a git hook that remove trailing whitespaces automatically before committing?
GuillaumeCisco (Wed, 23 Jan 2019 08:56:25 GMT):
Just added a new commit removing the trailing whitespace.
Furthermore, I think we should review how the enroll method work. Currently, it returns an Enrollment instance. Should it however returns an User object?
I based my register method from the Enrollment object, but from what I understand, it would be better to base it from an User object.
Thoughts ? @dexhunter

Will be a meeting settled tonight?
GuillaumeCisco (Thu, 24 Jan 2019 15:37:23 GMT):
Hello there, Just go back from testing the register method. As I can see in the Makefile : `TOX_VENV_NAMES = pylint flake8 py30 py35` We are testing once in py30 and in second time with py35. What's going on is the first time the registering will work, but the second time it will fail as we have already registered the user. The `fabric.server.db` is not cleaned. What should we do? launch a `make clean` between py30 and py35, override the db file for testing, removing the user on tearDown? I need help for this case @baohua @dexhunter @wangdong
baohua (Thu, 24 Jan 2019 16:34:54 GMT):
if tox support to clean after each venv, then we can delete the temp db. and i remember tox should auto setup a total clean env from scratch... feel free to pick up your efficient way.

GuillaumeCisco (Thu, 24 Jan 2019 20:04:39 GMT):
I'm not sure, because the DB file is automatically created from the fabric-ca-server-conf.yaml. The docker instance create it if it does not exist. So if I remove it between tests, I have to relaunch all the docker-compose setup. It won't work. Currently I use a random username as a fix. It allows me to register different users with each test suite environment, but I do not know if it is a good idea...
baohua (Fri, 25 Jan 2019 02:43:21 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=kgvPQg3kymWLrdnd2) @GuillaumeCisco Let's use different usernames first. and add comments in code to claim the reason to do so.

Has joined the channel.
GuillaumeCisco (Fri, 25 Jan 2019 09:49:56 GMT):
Thanks @baohua , I will do. I also discovered that we can remove an identity via `identity remove` but... right now... This method has not been implemented. I'll stuck with the random usernames for now.
Furthermore, I think I'm heading in the wrong direction. The current enroll method return a certificate, not an user. I'm waiting the next meeting for discussing about it.
What would be really useful is to know the specifications the node SDK used. It would be great to port their effort in python.
Right now, I deeply lack about informations.
dexhunter (Fri, 25 Jan 2019 16:50:34 GMT):
@GuillaumeCisco I think for node sdk they return a secret? https://github.com/hyperledger/fabric-sdk-node/blob/release-1.4/fabric-ca-client/lib/FabricCAClient.js#L94
dexhunter (Fri, 25 Jan 2019 16:54:50 GMT):
By the way, I think I am confused about the network problem. The problem with RxPy library is that the queue is empty, and we need to add extra timeout for retrieving the result. So I changed this asynchronous method back to synchronous method as FABP-185. However, with the synchronous I found there are still connection problems (but it does not happen every time, so it remains a mystery to me). I wonder if there are any ideas on why this might happen or suggestions where I should investigate? Thanks!

Thank you @dexhunter and @baohua . Great work.

FYI @Kelvin_Moutet is my coworker. We experience this error both.
I'm right now trying to implement the generateCRL method. It should follow the same way register and revoke do, if I'm referencing to the fabric-sdk-node. But I get an very weird error `[{'code': 20, 'message': 'Authentication failure'}]`. It looks like this issue happen if the user who wants to generateCRL does not have the `hf.GenCRL` set to true. As described here: https://jira.hyperledger.org/browse/FAB-7207?jql=text%20~%20%22generate%20CRL%22
We can see the same kind of issue with LDAP here: https://medium.com/@aleksobol/hyperledger-fabric-with-ldap-integration-part-2-eb87c2c95f39
https://jira.hyperledger.org/browse/FABC-729
I do not know how to pass this test and make it works.
@dexhunter I will create a jira issue and a branch with the code.
If you can take a look, it would be great :)

@Kelvin_Moutet Hi, could you also post the `network.json` file? Thanks!
dexhunter (Tue, 29 Jan 2019 10:14:10 GMT):
@GuillaumeCisco FABP-175 is about implementation of query methods
dexhunter (Tue, 29 Jan 2019 10:18:47 GMT):
you can check `e2e_test` to see (https://github.com/hyperledger/fabric-sdk-py/blob/master/test/integration/e2e_test.py#L294-L317). I also found there seems to be some problems regarding querying methods after I migrate from rxpy -> vanilla. But I am currently busy implementing new features, would have a look tomorrow (GMT+8)
dexhunter (Tue, 29 Jan 2019 10:19:38 GMT):
I pointed out the problem at TODO if you want to have a look
dexhunter (Tue, 29 Jan 2019 10:19:38 GMT):
I pointed out the problem at comment (TODO) if you want to have a look

dexhunter (Tue, 29 Jan 2019 10:26:11 GMT):
Right now I could see the peer name should be `peer1-myorg` but I am not sure if there are other problems.
dexhunter (Tue, 29 Jan 2019 10:27:04 GMT):
And org_name seems to be `myorg` in your case
Kelvin_Moutet (Tue, 29 Jan 2019 10:34:12 GMT):
Ah sorry, it's just renaming to keep it as clear as possible, I update the python call along to :)

cli = Client(net_profile="./network.json")
admin = cli.get_user('myorg', 'admin')
channel = cli.new_channel('mychannel')

GuillaumeCisco (Tue, 29 Jan 2019 11:14:03 GMT):
quick question, I'm implementing the `reenroll` method. What is best in your opinion:
```
# enroll
User = cacli.enroll(username, secret)
# reenroll
User = cacli.reenroll(User)
```
Or
```
# enroll
User = cacli.enroll(username, secret)
# reenroll
User.reenroll()
```

@GuillaumeCisco Hi, could you check the console logs? https://logs.hyperledger.org/production/vex-yul-hyp-jenkins-3/fabric-sdk-py-verify-x86_64/549/console.log.gz By the way, you can do `make check` before `git review` if you haven't done already. Thanks
GuillaumeCisco (Tue, 29 Jan 2019 15:14:19 GMT):
THank you @dexhunter I did not update these tests, only unit and integration, will do :)
GuillaumeCisco (Tue, 29 Jan 2019 15:14:19 GMT):
Thank you @dexhunter I did not update these tests, only unit and integration, will do :) (as make check take 35 minutes on my computer)
wangdong (Tue, 29 Jan 2019 15:28:41 GMT):
@GuillaumeCisco I think the first one is better.
GuillaumeCisco (Tue, 29 Jan 2019 15:38:49 GMT):
ok, I've just committed with test passing and with `User = cacli.reenroll(User)` way

dexhunter (Wed, 30 Jan 2019 00:02:01 GMT):
@GuillaumeCisco maybe you can just check the specific file something like `python3 -m tox -e py36 -- test/integration/ca_test.py` that would save you a lot of time
dexhunter (Wed, 30 Jan 2019 00:03:40 GMT):
By the way would you address the things @baohua mentioned in comments? Thanks!
baohua (Wed, 30 Jan 2019 00:06:38 GMT):
yeah, that quicker way is demonstrated in the documentation, too!

Hello everyone, I'm trying to understand how the client work to interact with my ledger but I see some "strange" things in the code like : https://github.com/hyperledger/fabric-sdk-py/blob/master/hfc/fabric/client.py#L816
Why 'businesschannel' is hardcoded here (and at other places too in the client.py file) ?

@Kelvin_Moutet hi, sorry for the late reply, I just traveled back home for Spring Festival. Yep, I agree that is problematic. Previously there is a parameter `channel_name` but someone told me is redundant then I removed it and use businesschannel as `send_install_proposal` method which just create a businesschannel. I will check whether to use system channel or the channel that chaincode running on. Thank you for rpeorting.

I guess it's the same difference as peer & channelpeer etc?

Hello, oh you already merged it, it seems that there are little work and discussion about my code ( Guillaume noticed some stuff by comparing it with fabrik sdk node)
We still can do it in another pull request :)
@dexhunter It seems that your method `query_instantiated_chaincodes` in `client.py` works but I don't know why the test (e2e) is commented
Moreover it seems we still need to do this in `chaincode_instantiate`
```
responses = utils.send_transaction(
self.orderers, tran_req, tx_context_tx)
```
I will check that today :)

by the way, did you guys how tx_id is passed in node sdk? I suppose there is a better way to do it than put inside the client instance.

Kelvin_Moutet (Thu, 31 Jan 2019 07:26:41 GMT):
Yes we see that for the `tx_id` (only used for the test).
Maybe we need to query/list all blocks/transactions to get one in it to test the methods
Kelvin_Moutet (Thu, 31 Jan 2019 07:27:40 GMT):
Guillaume maybe have info on it (It mainly him who looked in the fabric-sdk-node)
Kelvin_Moutet (Thu, 31 Jan 2019 07:30:57 GMT):

So if we need to contribute on this part of the code (invoke, instantiate, query, etc.) we push under this issue (https://jira.hyperledger.org/browse/FABP-175) on gerrit ?
dexhunter (Thu, 31 Jan 2019 08:17:09 GMT):
I suppose you can create a new jira issue and link it to FABP-175, but you can also just push to FABP-175. I suppose either way is fine.

GuillaumeCisco (Thu, 31 Jan 2019 08:48:37 GMT):
Hello guys, thank you for all your work and your reactiveness.
Kelvin removed a part in the code that should have not been removed. The `utils.send_transaction` part in the `chaincode_invoke` method.
Actually, this part is needed, otherwise nothing will be reflected to the other peers.
But, the real issue is these method should not even belong to the code. It should live in a tutorial or utils part. As described here: https://fabric-sdk-node.github.io/tutorial-channel-events.html (Transaction listener part). We can also see it in action here: https://github.com/hyperledger/fabric-samples/blob/release-1.4/fabcar/javascript-low-level/invoke.js
It does not belong to the SDK. But should be heavily documented and provided for allowing developper to understand how it works and give a basic implementation.
Right now, we do not have the channelEventHub part which is mandatory if we want to know our invoke transaction has been correctly validated to be synchronized among peers.
We will start working on this topic with my team, but it is not our priority and we will need active help.
Kelvin_Moutet (Thu, 31 Jan 2019 08:51:23 GMT):
I'm re-adding it and update the test along with :)
dexhunter (Thu, 31 Jan 2019 09:25:12 GMT):
@GuillaumeCisco Yes, I see your point. We should add more tutorials/explanations
GuillaumeCisco (Thu, 31 Jan 2019 09:33:21 GMT):
https://gerrit.hyperledger.org/r/#/c/29010/ and https://gerrit.hyperledger.org/r/#/c/29033/ have been rebased
GuillaumeCisco (Thu, 31 Jan 2019 09:36:52 GMT):
We will surely need asyncio.gather https://docs.python.org/3/library/asyncio-task.html#asyncio.gather for reproducing the `Promise.all` part of the fabric-sdk-node for knowing when the invoke transaction has been validated and will be reflected among peers
dexhunter (Thu, 31 Jan 2019 09:38:28 GMT):
yep, feel free to add that. We are planning to use async/await method.

dexhunter (Thu, 31 Jan 2019 13:16:55 GMT):
@GuillaumeCisco you can pull and pr again, right?
dexhunter (Thu, 31 Jan 2019 13:18:27 GMT):
@Kelvin_Moutet I can merge yours first if you want me to do the fixing. Or if you want to do the fixing I can merge mine first.
GuillaumeCisco (Thu, 31 Jan 2019 13:19:45 GMT):
@dexhunter Yes I'm doign it
GuillaumeCisco (Thu, 31 Jan 2019 13:19:45 GMT):
@dexhunter Yes I'm doing it
Kelvin_Moutet (Thu, 31 Jan 2019 13:20:22 GMT):
As you want, maybe it's easier to merge your pr first because it's late (utc+8 for you ) and I can rebase during this aftertnoon (utc+1 for me) and update my pr :)

@Kelvin_Moutet sure, let me ask someone else to review and merge the code ( I cannot merge the code myself)

@Kelvin_Moutet you can rebase to the master and fix the conflict now. thank you!
Kelvin_Moutet (Thu, 31 Jan 2019 13:33:42 GMT):
yep

for quick flake8 test you can do `python3 -m flake8 hfc test --exclude=protos` and it's very fast.

I will nearly push my pr rebased
There is a particular behavior with all query function which, if works return a dict, and in other case raise an exception or return a ProposalReponse.
Maybe we should review those functions and handle all case to return a clean, same type, response
GuillaumeCisco (Thu, 31 Jan 2019 15:15:42 GMT):
Thansk @dexhunter
GuillaumeCisco (Thu, 31 Jan 2019 15:15:42 GMT):
Thanks @dexhunter
dexhunter (Thu, 31 Jan 2019 15:15:47 GMT):
@Kelvin_Moutet hi, which one?
dexhunter (Thu, 31 Jan 2019 15:16:15 GMT):
yep, I agree
Kelvin_Moutet (Thu, 31 Jan 2019 15:16:47 GMT):
All `query_*` in `client.py`
Kelvin_Moutet (Thu, 31 Jan 2019 15:16:47 GMT):
All `query_*` functions in `client.py`
dexhunter (Thu, 31 Jan 2019 15:19:13 GMT):
The `query_*` functions in client should return `ProposalResponse`
dexhunter (Thu, 31 Jan 2019 15:19:55 GMT):
as in `channel.py` we use `send_tx_proposal`
dexhunter (Thu, 31 Jan 2019 15:20:18 GMT):
What do you suggest we return? @Kelvin_Moutet
dexhunter (Thu, 31 Jan 2019 15:21:28 GMT):
I see what do you mean by returning a dict. Yes, sometimes, we need to decode the block or something, so in client it's more specific
GuillaumeCisco (Thu, 31 Jan 2019 15:21:31 GMT):
I think the issue is with the dict return
Kelvin_Moutet (Thu, 31 Jan 2019 15:21:59 GMT):
Why we need to decode the block ?
Kelvin_Moutet (Thu, 31 Jan 2019 15:21:59 GMT):
Why do we need to decode the block ?
dexhunter (Thu, 31 Jan 2019 15:22:45 GMT):
if I remembered correctly, I was trying to align with node sdk or golang sdk
dexhunter (Thu, 31 Jan 2019 15:23:11 GMT):
and we do have a BlockDecoder class so I just used it
Kelvin_Moutet (Thu, 31 Jan 2019 15:25:07 GMT):
Okay, we surely need some investigation to see if it is still needed. I found it very strange to have to type of return possible !
Maybe @baohua can answer us :)
Kelvin_Moutet (Thu, 31 Jan 2019 15:25:07 GMT):
Okay, we surely need some investigation to see if it is still needed. I found it very strange to have two types of return possible !
Maybe @baohua can answer us :)
dexhunter (Thu, 31 Jan 2019 15:29:28 GMT):
yeah, I suppose you can give some suggestions from your production perspective
Kelvin_Moutet (Thu, 31 Jan 2019 15:32:49 GMT):
For instance , in case of `500`, we have no payload (so decode will fail), but there is better information to give to the client than an exception
```
response {
status: 500
message: "make sure the chaincode example_cc has been successfully instantiated and try again: chaincode example_cc not found"
}
```

We have an `status` and a `payload` :)

dexhunter (Thu, 31 Jan 2019 15:35:35 GMT):
we can just return the whole response in case of failure since I am not sure if all status == 500 are with a message? Can you confirm that if status != 200 then there will be a message?

Kelvin_Moutet (Thu, 31 Jan 2019 15:37:45 GMT):
If I remember well, when we used the `fabric-client` binary, we always have a message in case of `status != 200`
dexhunter (Thu, 31 Jan 2019 15:40:33 GMT):
okay, then I think we can add message to the logger in case of failure. I posted some comments at https://gerrit.hyperledger.org/r/#/c/29065/
Kelvin_Moutet (Thu, 31 Jan 2019 15:49:20 GMT):
Yep, I posted back :)

Kelvin_Moutet (Thu, 31 Jan 2019 16:04:35 GMT):

baohua (Thu, 31 Jan 2019 16:04:40 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=aDT3Ac3r8Y4aTcWGN) @Kelvin_Moutet yes, we should use the same return, e.g., all as Response type.
baohua (Thu, 31 Jan 2019 16:06:07 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=bv2irWA2sbZRqPf3G) @dexhunter 200 is the only OK case, otherwise, should include some error in msg, and in this case, payload might be None as it's in error.
Kelvin_Moutet (Thu, 31 Jan 2019 16:07:53 GMT):
@baohua So we should not decode the response.payload and return it but return directly the response in all status case and fail if we have no response ?
baohua (Thu, 31 Jan 2019 16:09:48 GMT):
In error case, we should not decode payload as you cannot handle all error results as the same format. But we can return error code and error msg (mostly from fabric directly) to indicate the reason, hence the client users know what happens.
baohua (Thu, 31 Jan 2019 16:12:16 GMT):
btw, i remember node sdk does not keep same response everywhere (which may be fixed later). we may make it easier with same processing and response format to end users.
baohua (Thu, 31 Jan 2019 16:12:16 GMT):

dexhunter (Thu, 31 Jan 2019 16:12:30 GMT):
@baohua to be more clear, in the ok case, we do decode the block and return the decoded result, is that right?
dexhunter (Thu, 31 Jan 2019 16:12:48 GMT):
I see
baohua (Thu, 31 Jan 2019 16:13:35 GMT):
for query blocks, we may.
Kelvin_Moutet (Thu, 31 Jan 2019 16:13:57 GMT):
@dexhunter Not sure, if we decode the block (the payload) we cannot return a ProposalReponse
Kelvin_Moutet (Thu, 31 Jan 2019 16:13:57 GMT):
@dexhunter Not sure, if we decode the block (the payload) we cannot return a ProposalReponse, because the decoded block become a dict
baohua (Thu, 31 Jan 2019 16:14:12 GMT):
we can cover the most popular case to bring convience for end-users, and provide more if there's extra requirement.
dexhunter (Thu, 31 Jan 2019 16:14:21 GMT):
but I don't think user can decode the block themselves?
baohua (Thu, 31 Jan 2019 16:14:28 GMT):
@Kelvin_Moutet what do you think?
baohua (Thu, 31 Jan 2019 16:14:45 GMT):
would end users expect a raw result or some decoded one.
baohua (Thu, 31 Jan 2019 16:14:45 GMT):
would end users expect a raw result or some decoded one when they call query block.
baohua (Thu, 31 Jan 2019 16:14:45 GMT):
would end users expect a raw result or some decoded one? when they call query block.
Kelvin_Moutet (Thu, 31 Jan 2019 16:15:24 GMT):
We can add a option in the function call
dexhunter (Thu, 31 Jan 2019 16:16:21 GMT):
the decode is actually done with protobuf, it seems to me very rare the user would need a raw block. (well, I am not quite sure though
Kelvin_Moutet (Thu, 31 Jan 2019 16:16:30 GMT):
decode=False -> raw result for status 200 and other
decode=True -> decode the payload block if possible (status 200), if not raise a error for all other status
dexhunter (Thu, 31 Jan 2019 16:16:50 GMT):
@Kelvin_Moutet an option parameter seems good
dexhunter (Thu, 31 Jan 2019 16:16:50 GMT):
@Kelvin_Moutet an optional parameter seems good
baohua (Thu, 31 Jan 2019 16:17:05 GMT):
sure, if there's real requirement for it. But please try to keep it extendiable (e.g., decode=True by default).
baohua (Thu, 31 Jan 2019 16:17:05 GMT):

Kelvin_Moutet (Thu, 31 Jan 2019 16:39:16 GMT):
https://gerrit.hyperledger.org/r/#/c/29065/ is updated with `decode` option
It allows us to use it with `decode=False` in `chaincode_invoke` and `chaincode_instantiate` to wait the ledger to take them into account (will be replace by channel event hub in the future)
dexhunter (Thu, 31 Jan 2019 16:45:12 GMT):
@GuillaumeCisco @Kelvin_Moutet Hi, just curious, are you guys integrating fabric with your federated learning framework? One of my research topics is actually related and I used to follow openmined project.
GuillaumeCisco (Thu, 31 Jan 2019 16:45:33 GMT):
yes
GuillaumeCisco (Thu, 31 Jan 2019 16:46:20 GMT):

GuillaumeCisco (Thu, 31 Jan 2019 17:02:13 GMT):
I've started working on the ChannelEventHub topic. here is the work in progress code: https://gerrit.hyperledger.org/r/#/c/29078/
I've basically translated the code from fabric-sdk-node, but there are a lot of zones of shadow in my mind.
Mainly: how does work the grpc stream for getting stream on info: https://github.com/hyperledger/fabric-sdk-node/blob/release-1.4/fabric-client/lib/ChannelEventHub.js#L392
For example, in the orderer class I can see things like in the fabric-sdk-node: https://github.com/hyperledger/fabric-sdk-node/blob/release-1.4/fabric-client/lib/Orderer.js#L119
When in the fabric-sdk-py we have only: https://github.com/hyperledger/fabric-sdk-py/blob/master/hfc/fabric/orderer.py#L113
I really need help to understand how it is working underneath.
If you can provide some documentation.
rsoeldner (Thu, 31 Jan 2019 19:42:53 GMT):
Is it right now possible to invoke a chaincode (nodejs) with an Enrollment ?

I am not sure what is the most proper way to do streaming in python either but a quick google shows something like: https://stackoverflow.com/questions/49580793/how-to-broadcast-in-grpc-from-server-to-client or https://github.com/melledijkstra/python-grpc-chat

# Query a chaincode

# The response should be true if succeed -> The response should be '400' if succeed

GuillaumeCisco (Fri, 01 Feb 2019 08:28:23 GMT):
The method `chaincode_invoke` in the client has been hard coded with a chaincode coded in GOLANG by the way: `cc_type=CC_TYPE_GOLANG`, so this method won't work with a chaincode coded in node.js.
GuillaumeCisco (Fri, 01 Feb 2019 08:29:05 GMT):
Note the code created by Kelvin with polling:
```
# Wait until chaincode invoke is really effective
# Note : we will remove this part when we have channel event hub
starttime = int(time.time())
while int(time.time()) - starttime < timeout:
try:
response = self.query_transaction(
requestor=requestor,

@GuillaumeCisco okay, just visited some relatives for Spring Festival and I'm back. I see what you mean. Short answer is we don't have documentations on this part (feel free to add one) and everything is at the code. Previously, it looks like: https://github.com/hyperledger/fabric-sdk-py/blob/1893f273ca2c68ecb64580714e2297d204ea3300/hfc/api/orderer.py#L39-L51 and I changed to synchronous method. The grpc streaming api requires an iterator and a list works fine but after reading node sdk, it seems we could add better handling for this streaming. Maybe under a Thread?

@Kelvin_Moutet sorry I didn't find that out, maybe you can fix it in the next patchset. Thank you!
GuillaumeCisco (Fri, 01 Feb 2019 15:32:37 GMT):
We pause our development on the ChannelEventHub implementation for focusing on the query and invoke of our chaincode with a fabric-ca tls environment
GuillaumeCisco (Fri, 01 Feb 2019 15:33:00 GMT):
Unfortunately, we are not able to query our chaincode with the tls certificate file passed.
GuillaumeCisco (Fri, 01 Feb 2019 15:35:42 GMT):
We use the one generated for the tls ca in the fabric-ca-server-config.yaml file:
```
tls:
# Enable TLS (default: false)
enabled: false
# TLS for the server's listening port
certfile: tls-ca-cert.pem # the one created here
keyfile:
clientauth:
type: noclientcert
certfiles:
```

The error we get when queying is `ssl_transport_security.cc:1229] Handshake failed with fatal error SSL_ERROR_SSL: error:1000007d:SSL routines:OPENSSL_internal:CERTIFICATE_VERIFY_FAILED.`
GuillaumeCisco (Fri, 01 Feb 2019 15:37:11 GMT):
However when testing with the network of the `fabric-sdk-py` with already generated cert, the `chaincode_invoke_test.py` works well.
GuillaumeCisco (Fri, 01 Feb 2019 15:39:36 GMT):
By default it use certificates located here: https://github.com/hyperledger/fabric-sdk-py/tree/master/test/fixtures/e2e_cli/crypto-config/peerOrganizations/org1.example.com/msp/tlscacerts as descrined in the `network.json` here: https://github.com/hyperledger/fabric-sdk-py/blob/master/test/fixtures/network.json#L92

I've tried creating a certificate by myself using these commands:
```
openssl ecparam -out org1.example.com.key -name prime256v1 -genkey

Create openssl.cnf like:

[ req ]
default_bits = 1024
default_md = sha256
default_keyfile = privkey.pem
distinguished_name = req_distinguished_name
attributes = req_attributes
req_extensions = v3_req

[ usr_cert ]
basicConstraints = CA:TRUE
keyUsage = digitalSignature, keyEncipherment, cRLSign, keyCertSign
extendedKeyUsage = anyExtendedKeyUsage
subjectKeyIdentifier = hash
#authorityKeyIdentifier = keyid,issuer
[ v3_req]
extendedKeyUsage = anyExtendedKeyUsage
basicConstraints = CA:FALSE
keyUsage = digitalSignature, keyEncipherment, cRLSign, keyCertSign
[ req_distinguished_name ]
countryName = Country Name (2 letter code)
countryName_default = AU
countryName_min = 2
countryName_max = 2
stateOrProvinceName = State or Province Name (full name)
stateOrProvinceName_default = Some-State
localityName = Locality Name (eg, city)
0.organizationName = Organization Name (eg, company)
0.organizationName_default = Internet Widgits Pty Ltd
organizationalUnitName = Organizational Unit Name (eg, section)
commonName = Common Name (e.g. server FQDN or YOUR name)
commonName_max = 64
emailAddress = Email Address
emailAddress_max = 64
# SET-ex3 = SET extension number 3
[ req_attributes ]
challengePassword = A challenge password
challengePassword_min = 4
challengePassword_max = 20
```
And ran command:
```
openssl req -config openssl.cnf -new -days 3650 -nodes -x509 -subj "/C=US/ST=California/L=San Francisco/O=org1.example.com/CN=tlsca.org1.example.com" -key org1.example.com.key -out org1.example.com.cert

Ok for more information, after a lot of testing, I'm not able to mimic a cert produced by the crypto material tools.I still do not know how to make TLS works with fabric-sdk-py
GuillaumeCisco (Thu, 07 Feb 2019 17:10:02 GMT):
THe way CAs are generated with cryptogen can be find here: https://github.com/hyperledger/fabric/blob/release-1.4/common/tools/cryptogen/ca/generator.go
GuillaumeCisco (Fri, 08 Feb 2019 10:52:09 GMT):
I finally found what is the issue. We have two location where the tls ca is verified
GuillaumeCisco (Fri, 08 Feb 2019 10:55:39 GMT):
one is the ca we send for making the call defined here `test/fixtures/e2e_cli/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/msp/tlscacerts/tlsca.org1.example.com-cert.pem`
And the one in the peer config, defined here `test/fixtures/e2e_cli/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt`
They need to be the same, and the `server.crt` and `server.key` in `test/fixtures/e2e_cli/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/` need to be related to it.
I'll try to update our project network for working correctly with it.
GuillaumeCisco (Fri, 08 Feb 2019 16:52:30 GMT):
ok great news. After a long week of investigation, I succeeded!
GuillaumeCisco (Fri, 08 Feb 2019 16:53:40 GMT):
I now have a question about the core.yaml file, especially this param `clientAuthRequired`, passing it to `true` triggers a certificate verify failed. Any idea how it works and what is its purpose?
GuillaumeCisco (Fri, 08 Feb 2019 16:53:40 GMT):

wangdong (Sun, 10 Feb 2019 09:02:19 GMT):
This should be used for client authentication by server.
dexhunter (Mon, 11 Feb 2019 04:07:28 GMT):
@GuillaumeCisco congrats on finding the cause of certificate failure. I am trying to help to debug genCRL error. The error msg is ` ValueError: generating CRL failed with errors [{'code': 20, 'message': 'Authentication failure'}]` while for other methods the authentication works fine. So I am guessing there might be missing parameters for auth of genCRL.
GuillaumeCisco (Mon, 11 Feb 2019 08:21:17 GMT):
Yes, @dexhunter I looked at the fabric SDK node. But found nothing. Does it work in fabric SDK node btw?
GuillaumeCisco (Mon, 11 Feb 2019 10:48:40 GMT):
My team and I will now focus on the channelEventHub topic. We will need help @dexhunter , especially regarding grpc channel handling
GuillaumeCisco (Mon, 11 Feb 2019 15:28:53 GMT):
I've just created a PR for having better return on the invoke command. I also highlight where we can trigger a `SSLV3_ALERT_BAD_CERTIFICATE` error in the tests.
https://gerrit.hyperledger.org/r/#/c/29235/
Feel free to review it @dexhunter
dexhunter (Mon, 11 Feb 2019 15:38:49 GMT):
@GuillaumeCisco it works with node sdk, the only difference I found so far is there is a ca name. Besides that, the client seems to be different. I am also trying to read the source code of fabric-ca to see why this happens.
GuillaumeCisco (Mon, 11 Feb 2019 15:44:54 GMT):

GuillaumeCisco (Mon, 11 Feb 2019 15:45:44 GMT):
Regarding the `caName` and `caname`, fabric-sdk-node does it twice. So I put it too. But I think the fabric-sdk-node is not right
Kelvin_Moutet (Mon, 11 Feb 2019 16:39:09 GMT):
@dexhunter It seems that we also need to add `hf.GenCRL: true` in the admin `attrs` of fabric-ca-server-config.yaml
Kelvin_Moutet (Mon, 11 Feb 2019 16:39:32 GMT):
But I still have the issue with genCRL
Kelvin_Moutet (Mon, 11 Feb 2019 16:39:32 GMT):
But I still have the same issue with genCRL
Kelvin_Moutet (Mon, 11 Feb 2019 17:24:49 GMT):
I manage to make it works :)
Kelvin_Moutet (Mon, 11 Feb 2019 17:26:48 GMT):
@dexhunter How can I patch the https://gerrit.hyperledger.org/r/#/c/29000/
Kelvin_Moutet (Mon, 11 Feb 2019 17:30:48 GMT):
Seems I found the way to : https://gerrit.hyperledger.org/r/#/c/29000/ @GuillaumeCisco
dexhunter (Mon, 11 Feb 2019 18:38:57 GMT):
@Kelvin_Moutet great! It seems I did not find the missing `hf.GenCRL`. And we should not modify the passing ca_name? How did you find this fix? (I'll help to fix the flake error)
dexhunter (Mon, 11 Feb 2019 20:29:51 GMT):
Maybe we can append more settings according to this: https://hyperledger-fabric-ca.readthedocs.io/en/latest/serverconfig.html
Kelvin_Moutet (Tue, 12 Feb 2019 07:09:00 GMT):
@dexhunter it seems that if ca_name is empty we should not pass the argument. But we do not know if this is `caname`or `caName`, do you have more insights on it ?
Kelvin_Moutet (Tue, 12 Feb 2019 07:13:05 GMT):
I think it `caname` and it should be the same as the ca name it the server config. In the fixtures, the ca : name: is not provided, so we should not providing it for the test. Maybe it would be better to add it in the conf and in the tests ?
Kelvin_Moutet (Tue, 12 Feb 2019 07:47:04 GMT):
`The –caname flag specifies the name of the CA to which this request is sent. In this example, the gencrl request is sent
to the default CA.``
Kelvin_Moutet (Tue, 12 Feb 2019 07:47:04 GMT):
`The –caname flag specifies the name of the CA to which this request is sent. In this example, the gencrl request is sent
to the default CA.`

Kelvin_Moutet (Tue, 12 Feb 2019 07:47:41 GMT):
if we have `caname=""` it will go to the default CA
Kelvin_Moutet (Tue, 12 Feb 2019 07:49:02 GMT):
but i'm trying to put `caname=fabric-ca` everywhere, after modifications, all work except genCRL ( it tried with caName and caname :() But with caname="" it still works
GuillaumeCisco (Tue, 12 Feb 2019 08:46:16 GMT):
We've just understood why it was not working. The authorization header was not correctly generated -> missing caname param

dexhunter (Wed, 13 Feb 2019 09:42:44 GMT):
Hi, I wonder should we update the Makefile so that the build on github could pass ci as well? (The error is https://travis-ci.com/hyperledger/fabric-sdk-py/jobs/177068089#L496) I think we can either change the travis ci config or use something like `python3 -m tox ...` but I understand this is not on priority just saying.
dexhunter (Wed, 13 Feb 2019 09:43:44 GMT):
@GuillaumeCisco haha, even if we finish the project early, there is always room for creating customized tools such as sign-transaction-offline in node sdk (https://github.com/hyperledger/fabric-sdk-node/blob/release-1.4/docs/tutorials/sign-transaction-offline.md)

@dexhunter I don't know if you tested `fabric-sdk-py` with the `clientAuthRequired` to true and ran tests for displaying the `SSLV3_ALERT_BAD_CERTIFICATE.` error.
I try to find out why it does appear but can find the root source of the problem, maybe we have to specify the peers with tls cert and key files?
I do not clearly understand how `clientAuthRequired` is working.

Any reasons why we are not passing the cert/key of the peer for tls mutual authentication?
GuillaumeCisco (Mon, 18 Feb 2019 16:26:08 GMT):
In the fabric-sdk-node, the cert/key seems to be supported: https://github.com/hyperledger/fabric-sdk-node/blob/0d24cec10f7a3e0153fcf3f0158a89c5eaa0cfab/fabric-client/lib/Remote.js#L268

Quick question, I need to know how to load it from the network API. Is there documentation about it?
dexhunter (Tue, 19 Feb 2019 04:45:47 GMT):
@GuillaumeCisco Sorry I was caught up with bccsp yesterday but I managed to change the signature algorithm now. What is the network API are you talking about? Is that `requests` or something else?
dexhunter (Tue, 19 Feb 2019 04:45:47 GMT):
@GuillaumeCisco Sorry I was caught up with bccsp yesterday but I managed to change the signature algorithm now. What is the network API are you talking about? ~Is that `requests` or something else?~ okay, I think we need to check the grpc docs

GuillaumeCisco (Tue, 19 Feb 2019 08:39:17 GMT):
Hey @dexhunter In fact, I found nothing about it in the docs. It looks like this is custom to `fabric-sdk-node`. What I call the Network API is the action of loading a config file `network.json` or `network-config.yaml` for initializing the network.
As we do in `fabric-sdk-py` with `network.json`. As far as I understand, this network API will be replaced by the `discover` API. I just wanted to know if there is any documentation on how to name keys in this particular file.
I'm just fixing test right now, I will create the issue and show you in details what I mean :)

@baohua @wangdong hi, in node sdk, they have this connection profile (https://fabric-sdk-node.github.io/tutorial-network-config.html), should we adopt the same in python sdk?

@baohua @wangdong hi, in node sdk, they have this connection profile (https://fabric-sdk-node.github.io/tutorial-network-config.html) since 1.1, should we adopt the same in python sdk?
wangdong (Sun, 24 Feb 2019 13:02:35 GMT):
At present, I do not find any reason not to adopt it. It is convenient and powerful.
wangdong (Sun, 24 Feb 2019 13:05:02 GMT):
do you have any different idea about this?
Kelvin_Moutet (Sun, 24 Feb 2019 13:09:44 GMT):
IMO, a connection profile should be limited to the entrypoint we need (e.g. a peer)
The rest should be gotten through the discover API, it is way more convenient.
We should not have to describe the full network to use it (imagine a network with 1000 orgs)
dexhunter (Sun, 24 Feb 2019 15:46:33 GMT):
@wangdong No, I don't

I was looking at `test/fixtures/e2e_cli/channel-artifacts/channel.json` and there is capabilities field here but no ordering service
nanspro (Sun, 24 Feb 2019 16:26:05 GMT):
To use sdk-py to change ordering service config what attributes should i change?
nanspro (Sun, 24 Feb 2019 16:31:13 GMT):
Change in ordering config means change in orderers right?
nanspro (Sun, 24 Feb 2019 16:31:13 GMT):
Changing configuration of ordering means changing the orderers right?
dexhunter (Sun, 24 Feb 2019 17:12:15 GMT):
@nanspro what orderer configs are you trying to change?
dexhunter (Mon, 25 Feb 2019 03:56:23 GMT):
hi, I think we also need to add msp, msp-manager, identity to the python sdk, is that right? Should I create related jira issues?
dexhunter (Mon, 25 Feb 2019 04:13:01 GMT):
hi, currently msp and related info are integrated inside `User`, I was wondering should we separate them back to individual class/files? @baohua @wangdong
nanspro (Mon, 25 Feb 2019 05:23:31 GMT):
@dexhunter i can't seem to find any orderer related info in `channel.json`
nanspro (Mon, 25 Feb 2019 05:25:36 GMT):
Orderers for a channel should be present in config file
nanspro (Mon, 25 Feb 2019 05:25:36 GMT):
I thought channel config should contain orderers object and it should be able to add and remove them
nanspro (Mon, 25 Feb 2019 05:33:26 GMT):
If client wants to change orderer attributes like `grpc_options` then he should be able to do so by changing channel.json(channel config)

@nanspro I think you should check `configtx.yaml` rather than `channel.json`

files at `channel-artifacts` are mostly generated by tools such as `configtxgen`

nanspro (Mon, 25 Feb 2019 12:29:25 GMT):
@dexhunter i checked out `configtx.yaml` and here is my understanding of the issue
1. Client should be able to change capabilities present in `channel.json`(only channel capability is present here so should we generate application and orderer capabilities from configtx?)
2. Client should be able to change orderer default values like (organisations, policies, batch timeout) so we need to create a orderer config generated from `configtx.yaml`(there exists `orderer.genesis.block` but to read data i think we might need orderer.json)
After getting proper config next step would be to read them and define api's to call each item
GuillaumeCisco (Mon, 25 Feb 2019 13:07:14 GMT):
I agree with @Kelvin_Moutet , the network loading way should be deprecated. The discover API is the way to go.
Regarding the channel API, can someone point us to any documentation?

baohua (Mon, 25 Feb 2019 13:19:01 GMT):
if i remember correctly, it's to dump the latest channel config --> json --> change the value --> serialize --> calculate diff --> send the update transaction to orderer.

I previously thought we should separate the identity, msp, msp_manager, etc as the nodejs sdk, but spending the whole day reading nodejs code and playing around my perception shifted. Our current implementation seems to be a more light-weight approach which I think is a supplement to the nodejs sdk. I implemented the identity, msp, msp_manager separately but now I think I will use a light-weight approach instead.

wangdong (Tue, 26 Feb 2019 07:00:01 GMT):
@GuillaumeCisco I agree with him too. But this load file shoul be the entry point.
GuillaumeCisco (Tue, 26 Feb 2019 08:46:26 GMT):
Yes @wangdong using a peer credential for discovering the network. As the network API does not exist, and has no documentation, we should not mimic something that is exclusively implemented in the node js part.
wangdong (Tue, 26 Feb 2019 08:48:05 GMT):
Yes, we should implment it more pythonic not as node style.
wangdong (Tue, 26 Feb 2019 08:48:52 GMT):
there are many this type of implementation in node sdk. I think the class or some will do this trick.
dexhunter (Tue, 26 Feb 2019 09:25:46 GMT):
@GuillaumeCisco I though `init_with_net_profile` is the network API you are talking about? I think it can co-exist with the discovery api?
dexhunter (Tue, 26 Feb 2019 09:28:51 GMT):
In node sdk, I can use a `Config` or give the file path to the config file, for the discovery api, there will be a target peer (I am not sure if it's also called anchor peer) that send a request for discovery

GuillaumeCisco (Tue, 26 Feb 2019 09:32:45 GMT):
Yes @dexhunter it can co-exist. But in my opinion, the network initialization should be deprecated.
GuillaumeCisco (Tue, 26 Feb 2019 09:33:15 GMT):
You can see in the hyperldger explorer project, that they use their own network API implementation too. This is very confusing.
dexhunter (Tue, 26 Feb 2019 09:35:28 GMT):
Let me check the explorer. I agree that we should make the sdk easier to use.
dexhunter (Tue, 26 Feb 2019 09:38:18 GMT):
@GuillaumeCisco Could you point me to the network API in hyperledger explorer you mentioned? Thanks.
dexhunter (Tue, 26 Feb 2019 09:39:04 GMT):
By the way, I though the explorer does not init the netwrok
dexhunter (Tue, 26 Feb 2019 09:39:21 GMT):
It's a dashboard to view the information of the network?
GuillaumeCisco (Tue, 26 Feb 2019 09:48:04 GMT):
yes it is, we will ask @Kelvin_Moutet as he spend a lot of time on this part
GuillaumeCisco (Tue, 26 Feb 2019 09:48:04 GMT):

@Kelvin_Moutet Thanks! I see they also config for the clients.
dexhunter (Tue, 26 Feb 2019 10:06:30 GMT):
For me, the confusing part is about peer and user (and the different roles such as anchor_peer, admin_peer?, admin_user?, etc.) but I am starting to get the point that it's just the same object with different roles depending on the definition
dexhunter (Tue, 26 Feb 2019 10:08:35 GMT):
Besides, tls, cert, ca part need extra care as well.

hi, there is a naming in python sdk I found a bit confusing `tx_prop_req`. In `proposal.proto` it says
> The proposal is basically a request to do something that will result on some action with impact on the ledger
So I was wondering to change it either to `tx_prop` or just `proposal`? What are your opinions on this?
Kelvin_Moutet (Wed, 27 Feb 2019 08:22:28 GMT):
In network communication, `tx` means transmission. Moreover, `tx_prop_req` is not something directly related to hyperledger fabric ? I think I already see this term in fabric code

dexhunter (Wed, 27 Feb 2019 09:09:23 GMT):
@Kelvin_Moutet I tried to grep `tx_prop_req` at fabric folder but I didn't find such a thing. `tx` means transaction in our implementation. I think I don't like the naming because it's similar to name something like `apple_fruit` which is ok but not necessary, `apple` would be just fine IMO.
Kelvin_Moutet (Wed, 27 Feb 2019 09:39:45 GMT):
Okay, so if its related only to the python sdk, seems legit to change it if it's more convenient :)
wangdong (Wed, 27 Feb 2019 13:59:06 GMT):
It is transaction requrest.
wangdong (Wed, 27 Feb 2019 13:59:06 GMT):
It is transaction proposal requrest.

When i use fabric-sdk-py to instantiate a new chaincode. i meet a error message like this :`error starting container: error starting container: Failed to generate platform-specific docker build: Error returned from build: 1 \"can\'t load package: package github.com/parcel` . After searching this problem by google, i guess this problem cause of cannot get chaincode package. But I havenot deep know fabric-sdk-py. I have used fabric-sdk-java. Hope your help.

nanspro (Thu, 28 Feb 2019 08:02:08 GMT):
@AlanLee could you tell me why you marked https://jira.hyperledger.org/browse/FABP-199 complete. It is still in progress and i'll share the design here soon.

@baohua yes, i vendored chaincode package. And i find in docker peer, the chaincode installed only 8k, the normal chaincode installed should have about 244k. And sir ,i have some doubt about that how to get channel existed when i want to install or instantiate chaincode. Now my method is
```
per_exist_channel = client.new_channel(per_channel_name)
for per_orderer_name in per_channel_value.get("orderers"):
per_exist_channel.add_orderer(client.get_orderer(per_orderer_name))
for per_peer_name, per_peer_value in per_channel_value.get("peers").items():
per_exist_channel.add_peer(client.get_peer(per_peer_name))
```
. Could you tell me whether this method is correct.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=86AZBC9ghqCExPKwf) @baohua ProposalResponse? Just checking on the `peer.proto`, the client sends a SignedProposal to the peer (endorser) and the peer will return a ProposalResponse.
```
service Endorser {
rpc ProcessProposal(SignedProposal) returns (ProposalResponse) {}
}
```
dexhunter (Thu, 28 Feb 2019 08:26:25 GMT):
@cccc Hi, I think you can do `client.get_channel(
dexhunter (Thu, 28 Feb 2019 08:28:29 GMT):
@cccc By the way, to create channel, please follow the tutorial (https://github.com/hyperledger/fabric-sdk-py/blob/master/docs/tutorial.md#2-operate-channels-with-fabric-network). Your current channel creation method does not seem right to me.
cccc (Thu, 28 Feb 2019 09:03:44 GMT):
@dexhunter sorry. I guess that you don't get my point. If a channel have been created in fabric network, how i should assign this channel to client._channels[channel_name]. The tutorial you mention will creat a new channel.
cccc (Thu, 28 Feb 2019 09:08:35 GMT):
And when i look source code, i find the hard code(https://github.com/hyperledger/fabric-sdk-py/blob/master/hfc/fabric/client.py#L338). Whether it is right?
GuillaumeCisco (Thu, 28 Feb 2019 09:38:33 GMT):

GuillaumeCisco (Thu, 28 Feb 2019 09:40:43 GMT):

looking a this test: https://github.com/hyperledger/fabric-sdk-node/blob/0d24cec10f7a3e0153fcf3f0158a89c5eaa0cfab/test/integration/e2e/join-channel.js#L74 It looks like we should use the orderer admin
baohua (Thu, 28 Feb 2019 13:44:50 GMT):
https://gerrit.hyperledger.org/r/#/c/29398/, welcome to help review
GuillaumeCisco (Thu, 28 Feb 2019 13:46:29 GMT):
@dexhunter does it still work to simply replace the `orderer_admin = self.get_user('orderer.example.com', 'Admin')` to `orderer_admin = self.get_user(orderer_name, 'Admin')`?
dexhunter (Thu, 28 Feb 2019 13:47:09 GMT):
@GuillaumeCisco just delete this line and change the next `tx_context` to ` tx_context = TXContext(requestor, ecies(), tx_prop_req)`
dexhunter (Thu, 28 Feb 2019 13:47:16 GMT):
:)
GuillaumeCisco (Thu, 28 Feb 2019 13:47:54 GMT):
I don't think we should do that, As the requestor need to be an admin
dexhunter (Thu, 28 Feb 2019 13:49:03 GMT):
I did not get the reason why not? Actually this line has nothing to with the orderer
dexhunter (Thu, 28 Feb 2019 13:49:13 GMT):
the orderer is defined above
dexhunter (Thu, 28 Feb 2019 13:49:24 GMT):
` orderer = self.get_orderer(orderer_name`
GuillaumeCisco (Thu, 28 Feb 2019 13:49:42 GMT):
I think only the orderer admin should request the genesis block
GuillaumeCisco (Thu, 28 Feb 2019 13:50:34 GMT):
it is more natural to me as described here: https://github.com/hyperledger/fabric-sdk-node/blob/0d24cec10f7a3e0153fcf3f0158a89c5eaa0cfab/test/integration/e2e/join-channel.js#L74
GuillaumeCisco (Thu, 28 Feb 2019 13:52:09 GMT):
I also think the hardcoded variable is due to a bad replace when the variable has been added in the signature method
dexhunter (Thu, 28 Feb 2019 13:56:56 GMT):
Hmm.. but I thought the requestor must be an admin? So are you suggesting that we should check whether the requestor is the orderer admin?

Hmm.. but I thought the orderer must be an admin? So are you suggesting that we should check whether the orderer is the orderer admin?
dexhunter (Thu, 28 Feb 2019 14:00:30 GMT):
Hmm... what do you mean by orderer admin? @GuillaumeCisco From my understanding, only a User have the role of either MEMBER or ADMIN, for msp, there are peers & orderers, but I don't know what's orderer admin?
baohua (Thu, 28 Feb 2019 14:04:01 GMT):
there are different organizations, orderer org is one.
dexhunter (Thu, 28 Feb 2019 14:04:05 GMT):
I am not sure if an requestor is not an admin could still make the operation though. I think you need to have the admin privilege to do it?
baohua (Thu, 28 Feb 2019 14:04:38 GMT):
there can be other non-orderer orgs like org1, org2
baohua (Thu, 28 Feb 2019 14:04:46 GMT):
who only owns some peer nodes
GuillaumeCisco (Thu, 28 Feb 2019 14:10:54 GMT):
In puth this in a nutshell, I think this hardcoded variable is just a forgotten review. Simply replacing it to `orderer_name` should do the trick

@GuillaumeCisco Nope, I don't think `orderer_name` has anything to do with the requestor. Maybe this could clarify things? https://github.com/hyperledger/fabric-sdk-node/blob/0d24cec10f/docs/tutorials/app-dev-env-setup.md#what-makes-up-a-hyperledger-fabric-application-development-environment
GuillaumeCisco (Thu, 28 Feb 2019 14:48:13 GMT):
I'm not opposing the requestor and the admin orderer. I just think we should only replace the hardcoded part `orderer.example.com` to `orderer_name`, this is the simpliest fix, and won't break anything.
As all the tests example I've looked at in the fabric-sdk-node use the admin orderer and not the requestor, I think we should do the same.
As described in the doc you've pointed out:
```
As discussed above, the orderer should be the first step to bootstrap (launch) a network. The orderer will need the initial configurations wrapped inside a genesis block. Follow the instructions here to use the configtxgen tool to generate a genesis.block. The output, a genesis block file for the orderer, will be used in the next step to launch the orderer node.
```
dexhunter (Thu, 28 Feb 2019 15:31:25 GMT):
@GuillaumeCisco Oh, I see your point. Will modify the code. Many thanks!
GuillaumeCisco (Thu, 28 Feb 2019 15:32:09 GMT):
no problem ;) These parts are very hard to put in a global thinking
dexhunter (Thu, 28 Feb 2019 15:32:57 GMT):
Yep, also thanks to @baohua for the previous comments. Yep, I think if there are some orgs with no orderer that will be problems

I don't quite remember details, but I think you need to create a `request` object with `transient` attribute and pass it to chaincode operation methods in sdk-node

@GuillaumeCisco I see. BTW, I think we should use `yaml` package instead of `json` since YAML is a superset of JSON
dexhunter (Wed, 06 Mar 2019 04:01:30 GMT):
Anyone used yapf for autoformat? https://github.com/google/yapf/

yaml introduce reference to objects which can be very confusing. Furthermore json is really close to the python dict object, very easy to read. And enhance performance in python. Yaml python support is poor (no reference handling). You can also easily stringify/load json data, not for yaml.
dexhunter (Wed, 06 Mar 2019 13:27:14 GMT):
@GuillaumeCisco I am not familiar with the object referencing you mentioned but I will check that later. The reason for yaml IMO is 1) yaml is a superset of json, which means you can use yaml to load json file but not the other way around as indicated there: https://stackoverflow.com/questions/1726802/what-is-the-difference-between-yaml-and-json-when-to-prefer-one-over-the-other 2) we can support both yaml and json configuration file for starting a fabric network
What others opinions? @wangdong @baohua @Kelvin_Moutet
Kelvin_Moutet (Wed, 06 Mar 2019 13:28:26 GMT):
I prefer json too
Kelvin_Moutet (Wed, 06 Mar 2019 13:31:59 GMT):
We can load json with yaml, but do we want a mix of .json files and .yaml file for the user
Kelvin_Moutet (Wed, 06 Mar 2019 13:31:59 GMT):

[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=26Xd3vcf3a4K79dDa) @dexhunter No worry, in most cases, json and yaml can convert to each other easily. Yaml is more readable for human with shorter length, while json is popular in python. We can feel free to pick the json one as start (e.g., the network.json config is json).

hi. When i use fabric-sdk-py, i encounter the problem that the vendor folder cannot be put into tar.gz . When i install chaincode with vendor folder, i debug the code, find run the section (https://github.com/hyperledger/fabric-sdk-py/blob/master/hfc/util/utils.py#L454), and raise ValueError("No chaincode file found!").
And i resolve the problem, the url of my commit is https://github.com/codeAndxv/fabric-sdk-py/commit/2284089c377081669d94e9f601f91e7cb5f2674d. Because i don't use lf id, and i don't have time to process cotribute. So please check the problem, and cosider whether is right.

@GuillaumeCisco but if don't add vendor folder, the chaincode instantiate failed
GuillaumeCisco (Thu, 07 Mar 2019 13:46:22 GMT):
isn't there a way to create a chaincode with autovendoring?
GuillaumeCisco (Thu, 07 Mar 2019 13:46:52 GMT):
From what I recall, the chaincode should includes its vendoring files
GuillaumeCisco (Thu, 07 Mar 2019 13:47:04 GMT):
Did you test without fabric-sdk-py? With the shell binaries?
cccc (Thu, 07 Mar 2019 13:58:57 GMT):
In my opinion, if the chaincode installed just uses the packages include in fabric-peer docker image, the chaincode instantiate without vendoro success too. If not, the instantiate will fail.

dexhunter (Sat, 09 Mar 2019 16:59:17 GMT):
@Kelvin_Moutet I posted some comments on the patchset. Well, the public function of `discovery` in node sdk is a wrapper for the private one and it also integrates with `initialize` method on Channel, and since we don't have `initialize` method yet I was wondering if it is necessary to wrap the private function up.

Hello I'd like an enlightenment about the `--waitForEvent` option.
In the doc we can read:
`--waitForEvent Whether to wait for the event from each peer's deliver filtered service signifying that the 'invoke' transaction has been committed successfully`
I'd like to know if the `commit` part relate to the endorser or the orderer. In another way: when we have waited for the event, is the block committed in the ledger from the orderer, or has it been only validated by the endorser peer?
wangdong (Thu, 14 Mar 2019 09:09:37 GMT):
This should be from peer when to commit the block
GuillaumeCisco (Thu, 14 Mar 2019 11:06:21 GMT):
We've just succeeded making the peer channel based event hub working fabric-sdk-py. Unfortunately we still have issues for supporting mutual tls
GuillaumeCisco (Thu, 14 Mar 2019 11:06:29 GMT):
As explained here: https://hyperledger-fabric.readthedocs.io/en/release-1.3/peer_event_services.html
GuillaumeCisco (Thu, 14 Mar 2019 11:06:43 GMT):
```
If mutual TLS is enabled on the peer, the TLS certificate hash must be set in the envelope’s channel header.
```
GuillaumeCisco (Thu, 14 Mar 2019 11:07:17 GMT):
we do not know how to compute this hash, we tried with a raw certificate, then a based64 certificate, and we still do not have events

GuillaumeCisco (Thu, 14 Mar 2019 11:20:12 GMT):
we can also see in the `common.proto`:
```
// If mutual TLS is employed, this represents
// the hash of the client's TLS certificate
bytes tls_cert_hash = 8;
```
GuillaumeCisco (Thu, 14 Mar 2019 11:20:34 GMT):

We think the right code is:
```
arr = root_cert.split(b'\n')
der = b''.join(arr[1:-2])
kwargs['tls_cert_hash'] = sha256(base64.b64decode(der)).digest()
```
but we still do not have success
baohua (Thu, 14 Mar 2019 14:51:30 GMT):
i guess `der = base64.b64decode(pem[1:-2])`
baohua (Thu, 14 Mar 2019 14:51:43 GMT):
according to https://stackoverflow.com/questions/22743415/what-are-the-differences-between-pem-cer-and-der/22743616
baohua (Thu, 14 Mar 2019 14:53:37 GMT):
Maybe can contact `troy@troyronda.com`, who wrote the golang tls cert hash code.

@GuillaumeCisco really great work on this.
wangdong (Fri, 15 Mar 2019 01:36:07 GMT):
@Kelvin_Moutet regarding the init function, I would like you to refer to the node sdk.
wangdong (Fri, 15 Mar 2019 01:38:54 GMT):
It would be good to put all the init work in this function. This discovery service should be one option requested by the sdk user.
wangdong (Fri, 15 Mar 2019 01:42:49 GMT):
when to init a channel, the msp config can be got for later endorsement verification.
wangdong (Fri, 15 Mar 2019 01:43:26 GMT):
Just my points for your consideration.
wangdong (Fri, 15 Mar 2019 01:53:47 GMT):
@GuillaumeCisco As I reviewed your code, I got some comments. This event service is channel based not the old one. So let's just decouple it from peer.
wangdong (Fri, 15 Mar 2019 02:05:45 GMT):
I got no time to review all the code. I will do this tomorrow.

[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=KoLGe5tdzwfyZan52) @dexhunter The shell peer binary has it False by default : https://hyperledger-fabric.readthedocs.io/en/release-1.4/commands/peerchaincode.html#peer-chaincode-invoke
I've just adapted it for being false by default too.
BVut as I said long time ago. The method we provide `chaincode_invoke` should not even belong to the client. It is more like an helper.
GuillaumeCisco (Fri, 15 Mar 2019 08:26:09 GMT):

wangdong (Sun, 17 Mar 2019 13:40:35 GMT):
@GuillaumeCisco The first event service is called eventhub which comes from peers. user would have to use it along with peer, creating an event service, connecting, listening the specific peer. But there were some problem with this design. You will have to take care all the details, connecting and disconnecting or reuse. People always get confused when to reuse it. And there are so many issue in this. And other users can not get the event service from other peers in the same channel. Then here comes the channel event service. It is based on channel. client can register the event service and it will not have to take care the peer. And the event will be distributed to the channel. The registered client can get them. 1. As I see your get_event is block event. There are three kind of events now, the other two are chain code and transaction 2. This kind of events should be asynchronous event. I did not get how did you cope with this. Previously we handle this with queue and rx module. But we planed to implement await/async. So the best design(from my mind) is to design this event service as standalone class and it should expose API to client or channel. Yes of course I am affected by nodejs sdk. I think it is a good reference.
dexhunter (Sun, 17 Mar 2019 16:05:07 GMT):
I thought the first eventhub (from peer) is deprecated, no?
dexhunter (Sun, 17 Mar 2019 16:08:14 GMT):
Just a remainder, the travis-ci build on github is still failing due to lack of configtxgen tool, I am not sure why it does not download the fabric-bin.
GuillaumeCisco (Sun, 17 Mar 2019 17:16:16 GMT):
Yes @wangdong . we've only implementend block events, and we decided to create the client on each peer by default. Everything is available from the client, no need to do some operations on the channel. Regarding the async/await, we are working on it. @Kelvin_Moutet is close to a solution.
wangdong (Mon, 18 Mar 2019 01:13:10 GMT):
@dexhunter yes, it is deprecated.
wangdong (Mon, 18 Mar 2019 01:31:16 GMT):
@GuillaumeCisco Ok. you will couple the event with client. I would like you to articulate your idea about this design so that we can discuss it.
wangdong (Mon, 18 Mar 2019 01:31:16 GMT):
@GuillaumeCisco Ok. you will couple the event with client. I would like you to articulate your idea about this design. I would like know more about it.

wangdong (Mon, 18 Mar 2019 01:39:03 GMT):
@dexhunter @baohua As I see, that two +2 has been done for this event patch. This is only my comments. If you think it is OK I am fine.
dexhunter (Mon, 18 Mar 2019 02:28:45 GMT):
@baohua I think we already have the update channel function ( https://github.com/hyperledger/fabric-sdk-py/blob/master/hfc/fabric/client.py#L562-L577 ), but I don't see the test, so I am just creating a test to see how to perform this operation and will update docs accordingly.
Kelvin_Moutet (Mon, 18 Mar 2019 08:48:38 GMT):
As grpc stream are not async generator/iterator, using async/await is not possible right now.

I'd like to draw attention about the `generate_channel_tx` from the client. Is it normal it calls the configtxgen binary? Shouldn't it be handled all by python??
dexhunter (Tue, 19 Mar 2019 02:03:31 GMT):
@GuillaumeCisco I agree with you on sdk should function more. But as far as I see, the binary tools are still necessary, although I guess we can just rewrite the function to the python sdk and besides, if I am remember correctly, we can also write support for python chaincodes
GuillaumeCisco (Tue, 19 Mar 2019 08:26:29 GMT):
Yes because it looks like we have the proto for this
GuillaumeCisco (Tue, 19 Mar 2019 08:30:52 GMT):
During my refacto with async, I've just discovered all the client methods do not work correctly, as there is only some things wrote like `responses[0][0]`. It is usually when we want a response from a peer, but doing this, we occult the responses of others peers. This is a big no no
GuillaumeCisco (Tue, 19 Mar 2019 08:31:36 GMT):

looks like `protos/idemix` is missing in the fabric-sdk-py protos. Should we add it @baohua ?
baohua (Wed, 20 Mar 2019 09:24:04 GMT):
Yes let's add it first!

I preserve the previous compatibility ! Feel free to comment :)

@GuillaumeCisco hi, if you don't specify the version for `aiogrpc`, will it work?
dexhunter (Thu, 21 Mar 2019 13:10:14 GMT):
@GuillaumeCisco hi, if you don't specify the version for `aiogrpc`, will it work? Because when I install `aiogrpc` it also installs `grpcio-1.19.0`

@GuillaumeCisco I reviewed the async code which are really great. Thanks for your effort. I got some comments. Please consider them.
wangdong (Sat, 23 Mar 2019 01:57:33 GMT):
And after the review, I got some thoughts about the code style and design work.
1. About the folded line: Our style now is a little ugly. We fold the line with will which break the lines unconditionally, making them unreadability.
2. About the variable naming: We should try our best to make the variables self-explained. The script languages like python, nodes make the variable reclaiming very cheap. people can acclaim variable as their will when they want.
But this is not good, especially for some big project. This will drive other developer crazy when to read the code. So I would like advise to not use the single letter variables, especially which spreads multiple lines or blocks.
One line style could be the exception.
3. About the patch size. Let’s break the big patch into small ones. It would be easy to review and the quality will be guarranteed. Small steps make great progress.
4. About the modularization, I would advise to make the low level service modulated, like discovery, event service. Later we will have more service enabled in fabric, token system, metrics service.
We make them modulated and it will be very flexible later for our job, making the sdk more scalable and the structure clear. So please reconsider this when to design the feature.

(I thought you fixed the aiogrpc==1.6?
tijohnson (Wed, 27 Mar 2019 15:11:06 GMT):
added a 'pip list' and sure enough aiogrpc is NOT there
tijohnson (Wed, 27 Mar 2019 15:11:32 GMT):
So I have to figure out what happened on my end
GuillaumeCisco (Wed, 27 Mar 2019 15:14:52 GMT):
I do not understand when you tell me `I thought you fixed the aiogrpc==1.6`. Because this is exactly what I tought too, I thought you fixed the aiogrpc==1.6, which is the original issue
tijohnson (Wed, 27 Mar 2019 15:18:28 GMT):
I did not change anything, it was '==' it should be '>=' like all the others in the requirements.txt
tijohnson (Wed, 27 Mar 2019 15:19:04 GMT):
no big deal, it did not effect the test, aiopgrpc is not there

something did not work, I will chase it down.

@tijohnson told me we cannot use `aiogrpc` due to the version of pip in the VM image which are based on python 2.7.
Thanks

not the whole grpc, but with the decorator for the function including grpc

Tox is installed with python 3.5, not python 3.6, so it will fail
GuillaumeCisco (Tue, 09 Apr 2019 07:36:41 GMT):
It could be great if you could provide a clean version of the Makefile so we can test it together
GuillaumeCisco (Tue, 09 Apr 2019 09:10:18 GMT):
I've just made an update to the Makefile, where tox is installed in the virtualenv, it will force him to use python 3.6, instead of current /usr/bin/python3 of the machine which is `3.5`>
I launched the build which should success as I can reproduce it on my machine, but it looks like the slaves are dead: https://jenkins.hyperledger.org/sandbox/view/fabric-sdk-py/job/fabric-sdk-py-verify-x86_64/
GuillaumeCisco (Tue, 09 Apr 2019 09:11:17 GMT):
@baohua do you know who is in charge to support the jenkins images for builds? And who has the power to provide a machine with python3.6 inside it and make it available for fabric-sdk-py project?
GuillaumeCisco (Tue, 09 Apr 2019 13:23:12 GMT):
Great news : https://jenkins.hyperledger.org/sandbox/blue/organizations/jenkins/fabric-sdk-py-verify-x86_64/detail/fabric-sdk-py-verify-x86_64/7/pipeline/

Has joined the channel.
tijohnson (Tue, 09 Apr 2019 16:46:39 GMT):
two parts to you change: ci-managment & fabric-sdk-py
the ci-managment changes tie fabric-sdk-py builds to hyp-x-test (new VM image)
The gerrit verify for your fabric-sdk-py changes will not pass until I merge in my ci-management change
tijohnson (Tue, 09 Apr 2019 16:54:30 GMT):
Unfortunately there is a bug in LF configure code the means that every night the hyp-x-test node is unusable until I manually fix each morning
that is next on my list
maral (Tue, 09 Apr 2019 23:01:07 GMT):
Hi, I am new to Python SDK. I would like to use Python SDK to connect to existing fabric network with existing channel and chaincode. It seems that Client operations in the tutorial do not work with an existing channel or chaincode. For example after initializing the client with network profile I would like to run query_instantiated_chaincodes on an existing channel. But I get AttributeError: 'NoneType' object has no attribute 'query_instantiated_chaincodes'. Am I missing something?

GuillaumeCisco (Wed, 10 Apr 2019 07:57:47 GMT):
@maral you need to manullay create a channel in the python memory
GuillaumeCisco (Wed, 10 Apr 2019 08:00:33 GMT):
```
from hfc.fabric import Client
cli = Client(net_profile='./network.json')
cli.new_channel('mychannel')
```
GuillaumeCisco (Wed, 10 Apr 2019 08:02:24 GMT):
hum after reading again, it seems there is another error, I will investigate.
GuillaumeCisco (Wed, 10 Apr 2019 08:18:26 GMT):
if we read the code: https://github.com/hyperledger/fabric-sdk-py/blob/master/hfc/fabric/client.py#L1275
```
channel = self.get_channel(channel_name)
tx_context = create_tx_context(requestor, requestor.cryptoSuite,
TXProposalRequest())
responses = channel.query_info(tx_context, target_peers)
```
It looks like the channel is not available in python memory from configuration.
So you should make fabric-sdk-py know about it by doing:
```
cli.new_channel('businesschannel')
```
just before.
Right now, it is not possible to declare channels from the json configuration, maybe it is something we'd like to change. toughts @baohua ?

You can check it @baohua I need to clean it again an little bit.
Moreover tutorial has been updated for handling async methods
baohua (Thu, 11 Apr 2019 14:59:12 GMT):
Nice progress!
GuillaumeCisco (Thu, 11 Apr 2019 15:35:02 GMT):
@baohua https://jenkins.hyperledger.org/blue/organizations/jenkins/fabric-sdk-py-verify-x86_64/detail/fabric-sdk-py-verify-x86_64/686/pipeline is ready for merge. It does not implement Channel Based Event Hub for now. But it *does* use events.
Furthermore, it is a breaking change as user now need to use asyncio for using the client. We need to have 0.0.8 version to be created and after that 0.0.9 and 1.0.0.
baohua (Thu, 11 Apr 2019 15:39:39 GMT):
ok, let's make it a todo for v0.9.0.
tijohnson (Thu, 11 Apr 2019 15:57:55 GMT):
@baohua @GuillaumeCisco This little 'exercise' required a little digging that exposed some problems with the CI configuration for the fabric-sdk-py project.
We have identified those issues and and I am working with the Hyperledger CI guys to get them addressed
@GuillaumeCisco Be sure to include me in the review of that script cleanup... it was a mess. Just make a simple change and send it out for review I will make comments about issues

@valentin994 What do you mean by `keys are hardcoded` ? In fact, the `network.json` file is a common pratice to give to the sdk the network information. Unfortunately, there is no official `network.json`, so each sdk define it differently (but try to have the same info)

We merged the 0.8.0 version but we can see this file is still on the 0.7.0 version: https://github.com/hyperledger/fabric-sdk-py/blob/master/hfc/version.py
wangdong (Wed, 17 Apr 2019 12:07:32 GMT):
@GuillaumeCisco I just see your info. does not spare time to read that.
wangdong (Wed, 17 Apr 2019 12:07:49 GMT):
yes, there are many unsed functions.
wangdong (Wed, 17 Apr 2019 12:09:49 GMT):
did you get your question resolved?
GuillaumeCisco (Wed, 17 Apr 2019 12:12:20 GMT):
which one @wangdong ?
wangdong (Wed, 17 Apr 2019 12:13:58 GMT):
eventhub
GuillaumeCisco (Wed, 17 Apr 2019 12:16:13 GMT):
not yet :/ On the 4 questions, 2 are remaining
GuillaumeCisco (Wed, 17 Apr 2019 12:18:12 GMT):
I have a new one too, regarding the `last_seen` possibility for the `start` option in the `connect` method of the fabric-sdk-node. I do not understand how it can work. Memoizing the last event to start from, I understand it. But from which context? I do not understand how they handle this, I will have to read the node sdk
wangdong (Wed, 17 Apr 2019 13:10:17 GMT):
I am not clear about this too.
GuillaumeCisco (Wed, 17 Apr 2019 13:15:13 GMT):
I've just updated the code too, in order to better handling chaincode invocation, using either transaction event or chaincode event

GuillaumeCisco (Fri, 19 Apr 2019 13:50:10 GMT):
curiously tests works on my machine but not everytime on the ci, I need to investigate on this, maybe a race condition, as we use event timeout in tests now
GuillaumeCisco (Fri, 19 Apr 2019 14:05:42 GMT):
it does not fail on pylint, py30, but in py36 teling me the chaincode is not instantiated on an invoke test, but just before we make sure the chaincode is instantiated. So I don't really understand why it could fail
GuillaumeCisco (Fri, 19 Apr 2019 14:19:38 GMT):
Ok I think we need more time: `16:18:35 test/integration/user_test.py Build timed out (after 20 minutes). Marking the build as failed.

@dexhunter can this module name with dash ?
wangdong (Wed, 24 Apr 2019 01:11:00 GMT):
I mean fabric-sdk-py, instead of fabric_sdk_py.
dexhunter (Wed, 24 Apr 2019 03:45:57 GMT):
@wangdong for the project name is can be fabric-sdk-py, but for the module name (when you do `import`) it should be fabric_sdk_py
wangdong (Wed, 24 Apr 2019 07:19:18 GMT):
ok

you mean `fabric`, `fabric-sdk` and `fabric-sdk-py`?

wangdong (Tue, 30 Apr 2019 02:45:47 GMT):
yes. that is it.
wangdong (Tue, 30 Apr 2019 02:46:36 GMT):
so we will use fabric-sdk-py as the wrapper name and fabric_sdk_py as the core name?
wangdong (Tue, 30 Apr 2019 02:48:53 GMT):
I think the `fabric-sdk-py` and `sdk` may be good. with core named `sdk`, inside, we will have fabric and fabric-ca. I think they are more clear to understand. Just my opinion in this.
baohua (Tue, 30 Apr 2019 03:34:04 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=RQ3urHJfnxJrRiNs3) @wangdong `sdk` feels too general, considering pypi already has numberous of sdks...
baohua (Tue, 30 Apr 2019 03:34:33 GMT):
hence at least should include the `fabric` or `hlf` into the name.

Hi, I recently started using the fabric-sdk-py and I was wondering where can I find all the available methods of the API, are there any others than those mentioned in the tutorial https://github.com/hyperledger/fabric-sdk-py/blob/master/docs/tutorial.md?
GuillaumeCisco (Thu, 02 May 2019 14:03:32 GMT):
Yes there are some more, you can check: https://github.com/hyperledger/fabric-sdk-py/blob/master/hfc/fabric/client.py
GuillaumeCisco (Thu, 02 May 2019 14:04:26 GMT):
fabric already exists on pypi too, I think, the best is too put hfc, no?
GuillaumeCisco (Thu, 02 May 2019 14:05:15 GMT):
I originally voted for `fabric-sdk` but `hfc` is better I think
haniavis (Thu, 02 May 2019 19:03:52 GMT):
OK thanks. I am trying to run the step by step tutorial
haniavis (Thu, 02 May 2019 19:04:21 GMT):
I can successfully run the first 2 steps but in 3 Operate Chaincodes with Fabric Network I always get an error

Traceback (most recent call last):
File "new/opCC.py", line 38, in
haniavis (Thu, 02 May 2019 19:05:38 GMT):
I can confirm that the channel is created in the previous step, I connect to the peer0.org1 container and see that there is the channel installed
haniavis (Thu, 02 May 2019 19:07:39 GMT):
and I also can confirm that the chaincode is installed (I print the responses variable)

@baohua I think we need to update the tutorial
GuillaumeCisco (Fri, 03 May 2019 07:33:41 GMT):
@haniavis what's going on is that your channel is correctly created, but the fabric-sdk-py doesn't know the channel in its python memory
GuillaumeCisco (Fri, 03 May 2019 07:34:40 GMT):
see https://chat.hyperledger.org/channel/fabric-sdk-py?msg=B7ZH5RcqJ6WsXZc7Z

ok thanks I will give it a try
haniavis (Fri, 03 May 2019 15:38:19 GMT):
Regarding the tutorial, sample.py also needs adjustments. The `if response: print("Join channel successful")` always gives successful but this is not true for any response. It also needs the async loop that is added in the step by step Tutorial.

@wangdong I don't really know of any documentation of this
indention is soo hard because there are so many ideas about what is 'best' this enforces one
this really helps minimizing white-space changes which can cause merge issues in git
tijohnson (Mon, 06 May 2019 15:31:03 GMT):
@all you should be able to run tox in your shell: 'tox -e coala' this runs MUCH quicker than 'tox' (which runs all the pylint checks)
it is no fun learning about an extra tab from the review verify build

@wangdong A primary issue is to have enough standardization with white-space/indent style that it minimizes white-space only changes which can cause merge issues with git

Yes, I can understand that. The test code style and other connfig files are really messy. It is good to make them consistent.
baohua (Thu, 09 May 2019 07:36:19 GMT):
@dexhunter so this week's meeting is canceled, right? See no agenda.
dexhunter (Thu, 09 May 2019 08:02:24 GMT):
yep, seems @GuillaumeCisco not online as well
dexhunter (Thu, 09 May 2019 08:03:22 GMT):
@here We will cancel this week's meeting due to low profile. Have a nice day!
GuillaumeCisco (Thu, 09 May 2019 08:15:02 GMT):

GuillaumeCisco (Thu, 09 May 2019 09:34:23 GMT):
[ ](https://chat.hyperledger.org/channel/fabric-sdk-py?msg=ByuLXBd4qPWJXGa4D) I'm fine with that too
GuillaumeCisco (Thu, 09 May 2019 09:36:58 GMT):
@hengfun you've only renamed the chaincode file? You should refer to it in the docker-compose file too them
GuillaumeCisco (Thu, 09 May 2019 09:36:58 GMT):
@hengfun you've only renamed the chaincode file? You should refer to it in the docker-compose file too then

I'm waiting for it to passes the test and will merge it, it is a very small modification for handling error
hengfun (Sat, 11 May 2019 05:04:26 GMT):
Hi does anyone know how to edit exampe_cc.go? I've been trying to edit it but when I run the tutorial example its not reflected.
hengfun (Sat, 11 May 2019 05:04:26 GMT):
Hi does anyone know how to edit exampe_cc.go? I've been trying to edit it but when I run the tutorial example my changes are not shown?
hengfun (Sun, 12 May 2019 06:04:38 GMT):
im editing the chain code in test/fixtures/chaincode/example_cc/example_cc.go, my changes aren't reflected in the install and invoke in docs/sample.py is it because the docker images have the example_cc.go already compiled on the docker images?
hengfun (Sun, 12 May 2019 06:04:38 GMT):

hengfun (Sun, 12 May 2019 06:04:38 GMT):
Hi guys, I would like to edit and customize "test/fixtures/chaincode/example_cc/example_cc.go" however my changes aren't reflected when I run the docs/sample.py or the tutorial.md specifically the install and invoke chaincode methods. I have been trying to debug this for a while with no progress any hints? @GuillaumeCisco @baohua @wangdong @dexhunter Thanks! Sorry to bother you guys.
GuillaumeCisco (Mon, 13 May 2019 11:56:39 GMT):
@hengfun you probably need to remove the docker chaincode image. I think `make clean` does this for you
hengfun (Mon, 13 May 2019 16:56:34 GMT):
@GuillaumeCisco Thanks I will give this a shot
baohua (Thu, 16 May 2019 06:34:21 GMT):
@here Seems few issues this week, will cancel this week's meeting, and let's discuss offline for any potential topics.

GuillaumeCisco (Mon, 20 May 2019 09:09:00 GMT):
After that, I think the channel event hub will be fully supported
GuillaumeCisco (Tue, 21 May 2019 09:06:09 GMT):
Can someone merge https://gerrit.hyperledger.org/r/#/c/fabric-sdk-py/+/31439/? @baohua , @dexhunter ? Thanks

When fabric-sdk-py 0.0.7 and 0.0.8 will be released ?
baohua (Thu, 23 May 2019 12:53:06 GMT):
We already have 0.8.0, the next one will be 0.9.0
Kelvin_Moutet (Thu, 23 May 2019 13:00:28 GMT):
Nope

GuillaumeCisco (Thu, 23 May 2019 13:38:53 GMT):
I have an issue guys
GuillaumeCisco (Thu, 23 May 2019 13:39:26 GMT):
If I push the 0.8.0 version on pypi, we need to update the 0.8.0 tag on gerrit to the last version of master
GuillaumeCisco (Thu, 23 May 2019 13:39:37 GMT):
As https://gerrit.hyperledger.org/r/#/c/fabric-sdk-py/+/31022/ has been merged
GuillaumeCisco (Thu, 23 May 2019 13:49:43 GMT):
ok guy I re-release the 0.8.0 version
GuillaumeCisco (Thu, 23 May 2019 13:51:13 GMT):
0.8.0 is now on pypi https://pypi.org/project/fabric-sdk-py/#history

I don't think this issue is still relevant: https://jira.hyperledger.org/browse/FABP-25
GuillaumeCisco (Thu, 23 May 2019 15:53:52 GMT):
this one seems outdated too: https://jira.hyperledger.org/browse/FABP-109
baohua (Fri, 24 May 2019 00:55:39 GMT):
@GuillaumeCisco sure, feel free to close then once done. i will do a check today.

baohua (Fri, 24 May 2019 07:48:29 GMT):
@GuillaumeCisco you mean mark it as done? Have you login into the jira?
baohua (Fri, 24 May 2019 07:48:38 GMT):
Everyone should be able to change the jira issue status.
GuillaumeCisco (Fri, 24 May 2019 08:09:03 GMT):
oh ? Where should I click, I see no buttons

baohua (Fri, 24 May 2019 13:43:47 GMT):
great!
baohua (Fri, 24 May 2019 13:46:57 GMT):
This is only to demo the discovering neighbor peers in the channel, right?
Kelvin_Moutet (Fri, 24 May 2019 14:05:35 GMT):
Yes, you're right. Neighbor peers and orderers in the channel.
But also discover the config of the peer
RodrigoMedeiros (Wed, 29 May 2019 17:17:29 GMT):
Has joined the channel.
dexhunter (Thu, 30 May 2019 02:43:34 GMT):

GuillaumeCisco (Thu, 30 May 2019 17:45:27 GMT):
I discovered some issues yesterday about mutual tls with the orderer. I successfully fixed it in the sdk, I will create a PR tomorrow about this. We then should deploy it as 0.8.1
GuillaumeCisco (Thu, 30 May 2019 17:46:09 GMT):
I also found an issue when trying to install a chaincode with vendor files. I fixed it too, and will create the PR tomorrow
baohua (Fri, 31 May 2019 07:40:07 GMT):
Great! @GuillaumeCisco
GuillaumeCisco (Fri, 31 May 2019 09:18:50 GMT):
It looks like there is also an issue with the instantiate method
GuillaumeCisco (Fri, 31 May 2019 09:19:04 GMT):
We cannot pass the policy right now, we will need to update it
GuillaumeCisco (Fri, 31 May 2019 09:20:07 GMT):
I will check how it is done on the fabric-sdk-node
GuillaumeCisco (Fri, 31 May 2019 09:26:45 GMT):
I found nothing :/
Where can we access the REST api documentation ?
GuillaumeCisco (Fri, 31 May 2019 09:28:20 GMT):
nevermind, we already support it in the sdk
baohua (Fri, 31 May 2019 13:48:48 GMT):
never heard that node-sdk has a REST api doc?
GuillaumeCisco (Fri, 31 May 2019 14:50:51 GMT):
you once gave it to me @baohua , I will find it, no worries
GuillaumeCisco (Fri, 31 May 2019 14:51:06 GMT):
by the way, can we do this method with the current fabric-sdk-py: https://hyperledger-fabric.readthedocs.io/en/release-1.4/commands/peerchannel.html#peer-channel-signconfigtx-example ?
baohua (Fri, 31 May 2019 14:53:58 GMT):
i do not think so, that's the update channel operation.
GuillaumeCisco (Fri, 31 May 2019 14:54:23 GMT):
by the way, this method `_get_latest_block` seems unused, I think we should remove it
baohua (Fri, 31 May 2019 14:55:23 GMT):
sure, either way is ok, we can safely keep it because it may be used later.
GuillaumeCisco (Fri, 31 May 2019 14:55:39 GMT):
Are you sure @baohua? I can see a `peer channel update`, a `peer channel signconfigtx` on the page
GuillaumeCisco (Fri, 31 May 2019 14:55:39 GMT):
Are you sure @baohua? I can see a `peer channel update` and a `peer channel signconfigtx` on the page
GuillaumeCisco (Fri, 31 May 2019 14:55:52 GMT):
ok
baohua (Fri, 31 May 2019 14:57:08 GMT):
let me check again.
GuillaumeCisco (Fri, 31 May 2019 14:57:16 GMT):
But I can see we have a `sign_channel_config`,maybe it is related to `signconfigtx`, I will try
GuillaumeCisco (Fri, 31 May 2019 14:57:16 GMT):
But I can see we have a `sign_channel_config`, maybe it is related to `signconfigtx`, I will try
GuillaumeCisco (Fri, 31 May 2019 14:57:46 GMT):
And `update_channel` should be related to `peer channel update`
baohua (Fri, 31 May 2019 15:00:24 GMT):
`sign_channel_config` is only used in `channel_create` now
GuillaumeCisco (Fri, 31 May 2019 16:37:33 GMT):
I'm think I'm developing a `channel_update` right now... And a lot of refactoring can be done. Furthermore, the `have_envolope` param seems never reached but looks like the `config_tx` file passed to the method. I will investigate that.
A lot of refactoring need to be done on fabric-sdk-py :/
GuillaumeCisco (Fri, 31 May 2019 16:44:18 GMT):
Does the `peer channel fetch` method exists in fabric-sdk-py?
GuillaumeCisco (Fri, 31 May 2019 16:48:01 GMT):
Looks like only `get_channel_config` exist
GuillaumeCisco (Fri, 31 May 2019 16:48:01 GMT):
Looks like only `get_channel_config` exists
baohua (Sat, 01 Jun 2019 09:28:09 GMT):
Agree with that, glad we have most functionalities now and can do some refactoring.
GuillaumeCisco (Mon, 03 Jun 2019 14:45:30 GMT):
I have an issue with the `get_channel_config` when trying to get the config of the system channel, named by default `testchainid`.
I always get an error which looks like:
```
grpc._channel._Rendezvous: <_Rendezvous of RPC that terminated with:
status = StatusCode.UNKNOWN
details = "access denied: channel [testchainid] creator org [Org1MSP]"
debug_error_string = "{"created":"@1559572059.608069311","description":"Error received from peer","file":"src/core/lib/surface/call.cc","file_line":1039,"grpc_message":"access denied: channel [testchainid] creator org [Org1MSP]","grpc_status":2}"
```
GuillaumeCisco (Mon, 03 Jun 2019 14:46:13 GMT):
It looks like only the orderer can fetch the `testchainid` config, confirmed in this issue too: https://lists.hyperledger.org/g/fabric/topic/some_questions_about_the/19215615?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,19215615

GuillaumeCisco (Mon, 03 Jun 2019 14:59:44 GMT):
The only hint I have, is maybe we should use a orderer broadcast instead of a peer delivery for this method. I need confirmation
GuillaumeCisco (Mon, 03 Jun 2019 14:59:44 GMT):

GuillaumeCisco (Mon, 03 Jun 2019 15:50:38 GMT):
it looks like we need to do an orderer broadcast, I will try to create this method
GuillaumeCisco (Mon, 03 Jun 2019 16:24:59 GMT):
ok I can assure this is the case after looking at the implementation of fabric-sdk-node
GuillaumeCisco (Tue, 04 Jun 2019 14:27:20 GMT):
I've successfully created this method
GuillaumeCisco (Tue, 04 Jun 2019 14:27:41 GMT):
I will create separate jira issues and PR, once my project run fully with the fabric-sdk-py
GuillaumeCisco (Tue, 04 Jun 2019 14:28:51 GMT):
I add to fix a lot of bugs, especially in decode functions. I also created channel update/upgrade methods

I'm happy to tell after a week of development, I've been able to use the fabric-sdk-py fully instead of the peer binary commands.
I will create in the next week, several jira issues with their related Pull Request.
There is a lot of bug fixes and new methods
GuillaumeCisco (Fri, 07 Jun 2019 17:22:22 GMT):
I spoke too quickly
GuillaumeCisco (Fri, 07 Jun 2019 17:22:51 GMT):
the invoke does not work due to endorsment_policy not being correctly sent to the instantiate/upgrade method
GuillaumeCisco (Fri, 07 Jun 2019 17:22:58 GMT):
I can see this has never been coded
GuillaumeCisco (Fri, 07 Jun 2019 17:23:19 GMT):
I will have to do this, for being able to make it works correctly
dexhunter (Wed, 12 Jun 2019 08:24:41 GMT):

GuillaumeCisco (Wed, 12 Jun 2019 12:38:25 GMT):
I have an issue when running tests after regenerating the config.
For example, on the master branch, I run the `integration/e2e_test.py` test, it works correctly.
I regenerate configs and artifacts with `make gen_config`, then retest the e2e_test, it fails
GuillaumeCisco (Wed, 12 Jun 2019 12:38:35 GMT):
Can someone confirm me this behavior?

standing up the sample network works fine, creating and joining the channel works fine, installing the chaincode works fine but instantiating, invoking does not. similar errors. Perhaps something was missed during my setup?
bbonetee (Wed, 12 Jun 2019 20:43:12 GMT):
O.K. - I found what to do from previous chat history, The sample tutorial should be updated to reflect this. spent quite a bit of time tracing this as the make check tests all pass only to look and see that invoke and instantiate are just "pass"

So this happens in the tutorial after you create channel and install chaincode - this all works up to that point in the tutorial, the tutorial should be updated to include adding the new_channel method.

Hello there, I've created a simple tool regarding endorsment policy transformation for it to work great with fabric-sdk-py.
I think I should put this code in the fabric-sdk-py code but I need your advice.
Basically it trasnforms endorsment policies https://hyperledger-fabric.readthedocs.io/en/release-1.4/endorsement-policies.html from string format to python dict and the opposite way.
policy declared like `OR('Org1.member', 'Org2.member')` will be transformed as:
```
{
'identities': [
{ 'role': { 'name': 'member', 'mspId': 'Org1' }},
{ 'role': { 'name': "member', 'mspId': 'Org2' }},
],
'policy': {
'1-of': [{ 'signed-by': 0}, { 'signed-by': 1 },]
}
}
```
It supports all logic `EXPR` (`OR`, `AND`, `OutOf`), I've added some tests, but I will need confirmation for some.
Will you be interested for putting this tool in fabric-sdk-py? I think it will be very helpful.

Hi all,
How can I create an instance of a registered user (to use it as a requestor to invoke chaincode).
I understand I have to use `cli.get_user` function -> but this needs the User's credential file paths to be present in the network.json (while creating connection)
I am fetching the user's key and certificate from a different place, How can I use them to generate a user instance?
madhukar_sh (Thu, 27 Jun 2019 12:00:33 GMT):
Do I have to create a new network profile for every user?
Kelvin_Moutet (Thu, 27 Jun 2019 12:35:16 GMT):
@madhukar_sh Nope, you have a `create_user` function or you can use the `User` class directly
madhukar_sh (Thu, 27 Jun 2019 12:39:01 GMT):
My bad, did not know there was a User class since it was not mentioned in tutorial / sample.... Any samples on how to use it? (I found one snippet in the integration test)

@Kelvin_Moutet thsi transitMap is for private data. You can find more examples about this in fabric doc.
Kelvin_Moutet (Mon, 01 Jul 2019 06:33:23 GMT):
@wangdong Yep I know :) But I never spend time to focus on this (and see how it works) !
wangdong (Mon, 01 Jul 2019 06:33:52 GMT):
OK.
wangdong (Mon, 01 Jul 2019 07:42:34 GMT):
so I guess you add this feature without a test?
wangdong (Mon, 01 Jul 2019 07:42:58 GMT):
If so, we may need a pr for this too.
Kelvin_Moutet (Mon, 01 Jul 2019 07:50:44 GMT):
I'm adding a test right now
Kelvin_Moutet (Mon, 01 Jul 2019 13:01:54 GMT):
I updated lot of stuff and add test for the transient_map. But I have an issue with `INVALID_ENDORSER_TRANSACTION`
https://gerrit.hyperledger.org/r/#/c/fabric-sdk-py/+/32132/
Kelvin_Moutet (Mon, 01 Jul 2019 13:02:14 GMT):
during chaincove invoke of the e2e_private_data_test
Kelvin_Moutet (Mon, 01 Jul 2019 13:06:16 GMT):
If someone can help me :) It's strange because it's nearly the same setup as e2e test (but with a different chaincode)
wangdong (Mon, 01 Jul 2019 13:52:01 GMT):
more detail will be better. I did not see this before. It is a bad endorsement?
wangdong (Mon, 01 Jul 2019 14:17:30 GMT):
you can refer to the fabric doc for what does ths mean exactly. This should be at protos/peer
Kelvin_Moutet (Mon, 01 Jul 2019 15:02:04 GMT):
Ah sorry I forgot to add the test
Kelvin_Moutet (Mon, 01 Jul 2019 15:02:35 GMT):
Add with patch 3 : https://gerrit.hyperledger.org/r/#/c/fabric-sdk-py/+/32132/
Kelvin_Moutet (Mon, 01 Jul 2019 15:03:25 GMT):
I try to do the invoke from https://hyperledger-fabric.readthedocs.io/en/release-1.4/private_data_tutorial.html#pd-install-instantiate-cc with frabic-sdk-py, and I got the invalid endorser transaction

Kelvin_Moutet (Mon, 01 Jul 2019 15:24:01 GMT):
here it is
Kelvin_Moutet (Tue, 02 Jul 2019 07:22:11 GMT):
`INVALID_ENDORSER_TRANSACTION` could come from https://github.com/hyperledger/fabric/blob/release-1.4/gossip/privdata/util.go#L151 or https://github.com/hyperledger/fabric/blob/release-1.4/core/common/validation/msgvalidation.go#L429
As the test is on private data, I think it comes from the first link.
Kelvin_Moutet (Tue, 02 Jul 2019 08:43:40 GMT):
After more investigation it seems that it comes from msg validation
Kelvin_Moutet (Tue, 02 Jul 2019 08:43:52 GMT):
I have a `2019-07-02 08:39:38.433 UTC [protoutils] ValidateTransaction -> DEBU 623 ValidateTransactionEnvelope returns err proposal hash does not match

Kelvin_Moutet (Tue, 02 Jul 2019 08:43:52 GMT):

Kelvin_Moutet (Tue, 02 Jul 2019 09:14:11 GMT):
We need to return a proposal without the transient map to be sent to the orderer
Kelvin_Moutet (Tue, 02 Jul 2019 09:44:15 GMT):
After fixing this, a issue still remains
Kelvin_Moutet (Tue, 02 Jul 2019 09:44:42 GMT):

https://jira.hyperledger.org/browse/FAB-13420
wangdong (Tue, 02 Jul 2019 12:55:39 GMT):
does this cause the failure of the test? This is just a warning.
Kelvin_Moutet (Tue, 02 Jul 2019 13:28:46 GMT):
We can get the public ledger data with the second org because it cannot fetch the block 2
Kelvin_Moutet (Tue, 02 Jul 2019 13:28:51 GMT):
but I found the issue
Kelvin_Moutet (Tue, 02 Jul 2019 13:28:59 GMT):
we need to setup the anchor peer
Kelvin_Moutet (Tue, 02 Jul 2019 13:34:12 GMT):
It now working
Kelvin_Moutet (Tue, 02 Jul 2019 13:34:12 GMT):
It's now working
Kelvin_Moutet (Tue, 02 Jul 2019 13:34:27 GMT):

ci fails, but it works on my computer :(
Kelvin_Moutet (Tue, 02 Jul 2019 14:18:03 GMT):
Can someone launch the test to see if there is any other issue
Kelvin_Moutet (Tue, 02 Jul 2019 15:01:25 GMT):
Okay, just a matter of time

Kelvin_Moutet (Tue, 02 Jul 2019 15:10:48 GMT):
It's a success :)
wangdong (Tue, 02 Jul 2019 23:03:17 GMT):
that's great.
wangdong (Tue, 02 Jul 2019 23:04:04 GMT):
yes, the anchor peer is required if the private data features is used.
baohua (Thu, 04 Jul 2019 07:44:15 GMT):
@wangdong @GuillaumeCisco let's have a quick sync today: https://wiki.hyperledger.org/display/fabric/2019-07-04. dixing will not be able to attend.

baohua (Thu, 11 Jul 2019 14:42:09 GMT):
Done!
GuillaumeCisco (Thu, 11 Jul 2019 14:46:30 GMT):
thanks @baohua !
wangdong (Thu, 11 Jul 2019 23:48:45 GMT):
@GuillaumeCisco what is the difference before and after?
wangdong (Thu, 11 Jul 2019 23:50:41 GMT):
it is collections_configs ?
wangdong (Thu, 11 Jul 2019 23:51:26 GMT):
This may be none, then it can not be added.
Kelvin_Moutet (Fri, 12 Jul 2019 05:59:06 GMT):
@wangdong If collections_configs is None, we should not pass a `CollectionConfigPackage()` as last argument to insure retro-compatibility with Application channel without at least v1_2 capabilities (for private data).
wangdong (Fri, 12 Jul 2019 09:19:38 GMT):
OK.
wangdong (Fri, 12 Jul 2019 09:20:02 GMT):
you guys are doing deep testing on the sdk?
GuillaumeCisco (Fri, 12 Jul 2019 09:55:38 GMT):
We use it in production
wangdong (Sat, 13 Jul 2019 02:13:32 GMT):
good to hear that.
wangdong (Sat, 13 Jul 2019 02:13:48 GMT):
you are the first customer I guess

Kelvin_Moutet (Thu, 18 Jul 2019 14:43:40 GMT):
Does someone know when the 0.8.1 will be released ?
baohua (Thu, 18 Jul 2019 14:58:35 GMT):
Last time talk with @wangdong in meeting, guess we can trigger recently.
baohua (Thu, 18 Jul 2019 14:58:48 GMT):
@Kelvin_Moutet any issues you think to block the release?
Kelvin_Moutet (Thu, 18 Jul 2019 15:01:28 GMT):
Nope, I think.
You have some issues in mind @GuillaumeCisco (if we don't take into account the refacto for the 0.9.0)
GuillaumeCisco (Thu, 18 Jul 2019 15:03:22 GMT):
No issues for me
baohua (Thu, 18 Jul 2019 15:45:02 GMT):
Then i think we can trigger! @wangdong what do you think
wangdong (Thu, 18 Jul 2019 23:02:57 GMT):
I am out of office yerterdat.
wangdong (Thu, 18 Jul 2019 23:02:57 GMT):

wangdong (Thu, 18 Jul 2019 23:03:19 GMT):

wangdong (Sun, 21 Jul 2019 10:34:45 GMT):
something wrong with my gerrit account. I have already fired a ticket for it.
GuillaumeCisco (Mon, 22 Jul 2019 08:35:08 GMT):
Hello guys, any news on the 0.8.1version?
GuillaumeCisco (Mon, 22 Jul 2019 08:35:27 GMT):
Do you want me to trigger the new versions on pypi and gerrit?
GuillaumeCisco (Mon, 22 Jul 2019 08:35:27 GMT):
Do you want me to trigger the new version on pypi and gerrit?
wangdong (Mon, 22 Jul 2019 09:43:44 GMT):
I have everything ready. But something wrong with my gerrit account. I can not login.
wangdong (Mon, 22 Jul 2019 09:44:01 GMT):
If you can do that, that will be great.

GuillaumeCisco (Thu, 25 Jul 2019 16:03:25 GMT):
I removed the py30 test, as we do not need it anymore due to new rx dependency
GuillaumeCisco (Thu, 25 Jul 2019 16:04:07 GMT):
the build has been successful in 19min54s. Our timeout is 20min, we should increase it
wangdong (Fri, 26 Jul 2019 01:48:30 GMT):
The build? You mean the local test process?
wangdong (Fri, 26 Jul 2019 01:48:45 GMT):
I have my gerrit issue resolved.
wangdong (Fri, 26 Jul 2019 02:00:39 GMT):
@GuillaumeCisco The patch is too big.
wangdong (Fri, 26 Jul 2019 02:00:39 GMT):
@GuillaumeCisco The patch is too big, including many topic. And code changes a lot. It would be better split it into small ones. It is good to reveiw.
wangdong (Fri, 26 Jul 2019 02:56:49 GMT):
could you please split it into some smaller? Especally for the big topic. Put the simples into one will be fine.
GuillaumeCisco (Fri, 26 Jul 2019 08:00:06 GMT):
I could but it will have no sense... Everything is interdependant
GuillaumeCisco (Fri, 26 Jul 2019 08:00:26 GMT):
can @Kelvin_Moutet and @baohua review please?
GuillaumeCisco (Fri, 26 Jul 2019 08:00:47 GMT):
by the way, did you retrieve your gerrit credentials for publishing the 0.8.1 release?
GuillaumeCisco (Fri, 26 Jul 2019 08:00:50 GMT):
would be great

GuillaumeCisco (Mon, 29 Jul 2019 08:37:33 GMT):
Shouldn't we use the last version of docker-compose which is : `docker-compose 1.24.1` ?
GuillaumeCisco (Mon, 29 Jul 2019 08:59:25 GMT):

OK. I will tag it soon.
wangdong (Mon, 29 Jul 2019 15:36:57 GMT):
I have reviewed your patches too. Thanks for your splitting which made the patch sets more clear and easy to read.
wangdong (Mon, 29 Jul 2019 15:37:02 GMT):
Thank you.
wangdong (Mon, 29 Jul 2019 15:37:09 GMT):
@GuillaumeCisco
GuillaumeCisco (Mon, 29 Jul 2019 15:37:37 GMT):
I will rebase the last one after we release 0.8.1 and we merge the little ones
GuillaumeCisco (Mon, 29 Jul 2019 15:37:51 GMT):
the modification will be available for a 0.8.2
wangdong (Mon, 29 Jul 2019 15:44:35 GMT):
OK. it seems I can not create new tag too.
wangdong (Mon, 29 Jul 2019 15:45:39 GMT):
@baohua
GuillaumeCisco (Mon, 29 Jul 2019 15:53:45 GMT):
do you want me to merge the revert commit @wangdong ?
wangdong (Mon, 29 Jul 2019 15:54:31 GMT):
I have revert it and I want to push again.
GuillaumeCisco (Mon, 29 Jul 2019 15:55:26 GMT):
do you want to submit https://gerrit.hyperledger.org/r/#/c/fabric-sdk-py/+/32564/ ?
wangdong (Mon, 29 Jul 2019 15:56:26 GMT):
this is the release patch.
wangdong (Mon, 29 Jul 2019 15:57:16 GMT):
I got the tag as 0.8.1 before. Is that cause?
wangdong (Mon, 29 Jul 2019 15:57:28 GMT):
it should be v0.8.1
GuillaumeCisco (Mon, 29 Jul 2019 15:57:57 GMT):
I don't understand what you are trying to achieve
GuillaumeCisco (Mon, 29 Jul 2019 15:58:05 GMT):
this PR is about reverting to 0.8.0
wangdong (Mon, 29 Jul 2019 15:58:46 GMT):
It is supposed to be a new release after I pushed the new patch.
wangdong (Mon, 29 Jul 2019 15:59:02 GMT):
we should also see it in github.
GuillaumeCisco (Mon, 29 Jul 2019 16:01:32 GMT):
Ok I'm lost
GuillaumeCisco (Mon, 29 Jul 2019 16:01:48 GMT):
I have to go, see you tomorrow
wangdong (Mon, 29 Jul 2019 23:34:45 GMT):
I have pushed the new tag. New release v0.8.1 done.
wangdong (Mon, 29 Jul 2019 23:34:51 GMT):
:grimacing:
wangdong (Tue, 30 Jul 2019 01:03:12 GMT):
I have to checkout to a new branch to push the tag? I can not push the tags to master last night.

GuillaumeCisco (Tue, 30 Jul 2019 07:23:59 GMT):
great @wangdong
GuillaumeCisco (Tue, 30 Jul 2019 07:24:12 GMT):
But I think we will have to untag the version: https://github.com/hyperledger/fabric-sdk-py/commits/v0.8.1
GuillaumeCisco (Tue, 30 Jul 2019 07:24:30 GMT):
As you can see, the merge from @baohua has been included
GuillaumeCisco (Tue, 30 Jul 2019 07:24:52 GMT):
It should not be present in this version...
GuillaumeCisco (Tue, 30 Jul 2019 07:27:01 GMT):
@madhukar_sh https://jira.hyperledger.org/browse/FAB-14145?workflowName=FAB%3A+Bug+Workflow&stepId=2
madhukar_sh (Tue, 30 Jul 2019 07:28:31 GMT):
Yes, I did see that
madhukar_sh (Tue, 30 Jul 2019 07:29:39 GMT):
Since this is the fist Put query, the read set should be empty...
madhukar_sh (Tue, 30 Jul 2019 07:29:54 GMT):
Or say, Empty couchDB database
wangdong (Tue, 30 Jul 2019 09:08:05 GMT):
@GuillaumeCisco Yes, there are two merges. This guy worked so late.
wangdong (Tue, 30 Jul 2019 09:08:50 GMT):
But I wonder does it matter greatly. These two patches are all about the bug fixes.
wangdong (Tue, 30 Jul 2019 09:09:50 GMT):
anyway let me try to tag before them.
GuillaumeCisco (Tue, 30 Jul 2019 09:12:03 GMT):
yes it matters a lot !
GuillaumeCisco (Tue, 30 Jul 2019 09:12:14 GMT):
you should untag et retag it
GuillaumeCisco (Tue, 30 Jul 2019 09:12:27 GMT):
how did you get the rights for tagging? Did you do something special?
GuillaumeCisco (Tue, 30 Jul 2019 09:12:33 GMT):
I could do it too
wangdong (Tue, 30 Jul 2019 09:20:05 GMT):
fix it.
wangdong (Tue, 30 Jul 2019 09:20:19 GMT):
and done.
GuillaumeCisco (Tue, 30 Jul 2019 14:17:31 GMT):
well done
GuillaumeCisco (Tue, 30 Jul 2019 14:17:40 GMT):

only three issue remaining in https://jira.hyperledger.org/projects/FABP/issues/FABP-33?filter=allopenissues
GuillaumeCisco (Mon, 05 Aug 2019 08:38:13 GMT):
We could create issues for refactoring channel/client files. creating MSPManager, Idemix, And review setMutualTLS
GuillaumeCisco (Mon, 05 Aug 2019 08:38:13 GMT):

Agree!
baohua (Thu, 08 Aug 2019 08:08:30 GMT):
@dexhunter @wangdong @GuillaumeCisco Should we discuss today? We've 0.8.1 cut last week: https://github.com/hyperledger/fabric-sdk-py/releases/tag/v0.8.1.
dexhunter (Thu, 08 Aug 2019 08:16:03 GMT):
@baohua sure, I am available today
dexhunter (Thu, 08 Aug 2019 08:21:42 GMT):
@here Dear all, we will have meeting 9PM this Thursday evening, pls help update the agenda at https://wiki.hyperledger.org/display/fabric/2019-08-08 welcome to attend, thanks!
GuillaumeCisco (Thu, 08 Aug 2019 08:37:17 GMT):
Yes we should release the 0.8.2 with an updated tutorial
GuillaumeCisco (Thu, 08 Aug 2019 13:45:54 GMT):
Is there a project regarding implementing chaincode with python like the one in node js: https://github.com/hyperledger/fabric-chaincode-node ?
GuillaumeCisco (Thu, 08 Aug 2019 13:46:10 GMT):
Would be great to write chaincode in python for isomorphism solutions
dexhunter (Thu, 08 Aug 2019 15:12:02 GMT):
yes, would be really nice if there are python support for chaincode
dexhunter (Thu, 08 Aug 2019 15:12:02 GMT):
yes, would be really nice if there is python support for chaincode
GuillaumeCisco (Thu, 08 Aug 2019 16:12:47 GMT):
I see there is no idemix support for fabric-sdk-node, only for fabric-sdk-java
GuillaumeCisco (Thu, 08 Aug 2019 16:12:52 GMT):
is it normal?
GuillaumeCisco (Fri, 09 Aug 2019 13:36:56 GMT):
Here is the document for implementing idemix in fabric-sdk-node: https://docs.google.com/document/d/12iJUJ0GsSDCoMKnMalbvchFHJveWj5LxOTGrIYlk04g/edit
GuillaumeCisco (Fri, 09 Aug 2019 13:37:10 GMT):
issue is: https://jira.hyperledger.org/browse/FABN-689
GuillaumeCisco (Fri, 09 Aug 2019 13:37:27 GMT):
seems nothing since april
GuillaumeCisco (Mon, 12 Aug 2019 08:25:59 GMT):
Ok guys, idemix seems far more complicated than I thought (only sending request to the fabric-ca).
Here is my message on the topic: https://lists.hyperledger.org/g/fabric/message/6625
wangdong (Wed, 14 Aug 2019 02:50:15 GMT):
yes, that's too complicated. As I know the inital functionality is implemented now.
baohua (Wed, 14 Aug 2019 06:32:07 GMT):
idemix is not that mature now, still have some known shortcoming. I think we can put it as low priority.
GuillaumeCisco (Wed, 14 Aug 2019 07:47:21 GMT):
Ok so we are not waiting for it for releasing the 1.0.0?
dexhunter (Thu, 15 Aug 2019 06:32:22 GMT):
@here We will cancel this week's meeting, please sync offline, thank you!
baohua (Fri, 16 Aug 2019 04:15:11 GMT):

Hello guys, I'm back from holliday
GuillaumeCisco (Mon, 02 Sep 2019 14:37:36 GMT):
I wonder, is there some rsa support right now in fabric-sdk-py?
GuillaumeCisco (Mon, 02 Sep 2019 14:38:02 GMT):
looks like no, I only see Ecies for ECDSA
GuillaumeCisco (Mon, 02 Sep 2019 14:38:24 GMT):
can someone confirm me that
GuillaumeCisco (Tue, 03 Sep 2019 14:17:10 GMT):
just post an article about RSA support here: https://lists.hyperledger.org/g/fabric/message/6738
GuillaumeCisco (Tue, 03 Sep 2019 14:17:42 GMT):
I also began writing the implementation of RSA in the fabric-sdk-py, but I cannot keep going if the basic go code does not support it
AlbertCL (Wed, 04 Sep 2019 06:24:17 GMT):
contribute

Right rsa is not supported. Think we can cut a 0.9.0 release now?
GuillaumeCisco (Fri, 06 Sep 2019 07:26:29 GMT):
Yes
GuillaumeCisco (Fri, 06 Sep 2019 08:21:08 GMT):
@baohua with my refactoring of the channel event hub, I think I forgot to update the chaincode_upgrade method. We are testing it right now, and it failed in our process, I'm on it, and think I've just found the issue, we will need to make a quick fix
GuillaumeCisco (Fri, 06 Sep 2019 08:47:23 GMT):

baohua (Fri, 06 Sep 2019 16:17:18 GMT):
Besides, should we consider to make the 0.9.0 release now?
GuillaumeCisco (Mon, 09 Sep 2019 08:10:44 GMT):
I think so
GuillaumeCisco (Mon, 09 Sep 2019 08:11:09 GMT):
maybe we should review the tutorial one more time
GuillaumeCisco (Mon, 09 Sep 2019 08:11:21 GMT):
I think I've seen some inconsistencies with the code
GuillaumeCisco (Tue, 10 Sep 2019 08:41:04 GMT):
I'm looking at https://hyperledger-fabric.readthedocs.io/en/release-1.4/developapps/application.html#gateway and I see we can define some strategies regarding channel event service, it could be a great feature to add
baohua (Tue, 10 Sep 2019 20:36:32 GMT):
I agree, the event part is very important and not easy to handle.
dexhunter (Wed, 11 Sep 2019 11:03:05 GMT):

Hi all, I have some problems for couchdb index installation with fabric-sdk-py, could I ask in this channel?
GuillaumeCisco (Thu, 12 Sep 2019 08:08:37 GMT):
Yes, but sorry, I won't be of any help, never used couchdb yet
mikeyangyo (Thu, 12 Sep 2019 10:38:03 GMT):
ok thanks
mikeyangyo (Thu, 12 Sep 2019 10:40:23 GMT):
My problem is that I need to install couchdb index when chaincode installation to perform complex query
mikeyangyo (Thu, 12 Sep 2019 10:40:46 GMT):
But i could not find arguments for chaincode install function to point out the index folder
baohua (Thu, 12 Sep 2019 17:20:28 GMT):
@mikeyangyo what kind of parameter for that in Node SDK?
mikeyangyo (Fri, 13 Sep 2019 04:47:25 GMT):
@baohua
is metadataPath in installChaincode request
mikeyangyo (Fri, 13 Sep 2019 04:47:49 GMT):
you could found in this tutorial
https://github.com/hyperledger/fabric-sdk-node/blob/release-1.4/docs/tutorials/metadata-chaincode.md
mikeyangyo (Fri, 13 Sep 2019 04:48:54 GMT):
this argument is the path of couchDB index folder
mikeyangyo (Fri, 13 Sep 2019 04:50:58 GMT):
but if you use command to install chaincode
it will find the index folder hierarchy such like META-INF/statedb/couchdb/indexes in chaincode folder
mikeyangyo (Wed, 18 Sep 2019 09:32:12 GMT):
Hi all, Is anyone ever use ca-service with fabric-sdk-py?
mikeyangyo (Wed, 18 Sep 2019 09:32:56 GMT):
I register a new user with my ca service, and enroll it to get the enrollment object
mikeyangyo (Wed, 18 Sep 2019 09:33:26 GMT):
I try to save it as a physic file to pass it to network json file
mikeyangyo (Wed, 18 Sep 2019 09:34:14 GMT):
but when i try to query from ledger with this user, I got some error msg
mikeyangyo (Wed, 18 Sep 2019 09:34:52 GMT):
Such like
access denied: channel [CHANNEL_NAME] creator org [ORG_MSPID]
mikeyangyo (Wed, 18 Sep 2019 09:35:56 GMT):
And I found error msg in peer container which is
the supplied identity is not valid: x509: certificate signed by unknown authority
mikeyangyo (Wed, 18 Sep 2019 09:38:06 GMT):

we use it @mikeyangyo
GuillaumeCisco (Thu, 19 Sep 2019 07:33:30 GMT):
we simply save the private key returned by fabric-sdk-py ca_service to a file, and then make it available to a Peer or User instance
mikeyangyo (Thu, 19 Sep 2019 10:10:02 GMT):
@GuillaumeCisco Do you use private_bytes function to store private key to a file?
GuillaumeCisco (Thu, 19 Sep 2019 12:23:18 GMT):
no
GuillaumeCisco (Thu, 19 Sep 2019 12:23:38 GMT):
oh sorry yes we do
GuillaumeCisco (Thu, 19 Sep 2019 12:23:43 GMT):
just checkout the code
GuillaumeCisco (Thu, 19 Sep 2019 12:24:02 GMT):
here is a sample:
```
private_key = enrollment._private_key.private_bytes(encoding=serialization.Encoding.PEM,
format=serialization.PrivateFormat.PKCS8,
encryption_algorithm=serialization.NoEncryption())
filename = os.path.join(msp_dir, 'keystore', 'key.pem')
writeFile(filename, private_key)
```
GuillaumeCisco (Thu, 19 Sep 2019 12:24:42 GMT):
```
def writeFile(filename, content):
os.makedirs(os.path.dirname(filename), exist_ok=True)
with open(filename, 'wb') as f:
f.write(content)
```\

```
GuillaumeCisco (Thu, 19 Sep 2019 12:25:13 GMT):
enrollment is just a
```
enrollment = cacli.enroll(user['name'],
user['pass'],
csr=csr,
profile=profile,
attr_reqs=attr_reqs)
```
GuillaumeCisco (Thu, 19 Sep 2019 12:26:09 GMT):

Hi. I am using `docker-compose-2orgs-4peers-tls.yaml` to create the network and `test/sample.py` to interact with my chaincode. Everything is working fine. However, without restarting the network, if I try to query chaincode using another python code, it gives error.
`cc_name='example_cc'
File "/usr/lib/python3.6/asyncio/base_events.py", line 484, in run_until_complete
return future.result()

channel_name).send_tx_proposal(tx_context, target_peers)
AttributeError: 'NoneType' object has no attribute 'send_tx_proposal'
`
Do I need to use the same `loop=ayncio.get_event_loop()` for all interactions? What if I want to interact with cc using multiple different programs?
Without using asyncio, I get this error:
`sys:1: RuntimeWarning: coroutine 'Client.chaincode_query' was never awaited`

prabal (Fri, 20 Sep 2019 04:35:26 GMT):
In `hfc/fabric/client.py` the `_channels` dict seems to get populated only if new channel is created. Is this the intended behaviour? How will query on existing channels and chaincodes work? The `get_channel` function returns `None` in those cases, resulting in the aforementioned error.
mikeyangyo (Mon, 23 Sep 2019 06:15:24 GMT):
@GuillaumeCisco Thanks for your sample, I will test it.
GuillaumeCisco (Mon, 23 Sep 2019 07:21:05 GMT):
you need to instanciate a channel. Currently the network.json does not deal with channel. A next update will do that.
prabal (Tue, 24 Sep 2019 09:46:53 GMT):
Thanks
prabal (Tue, 24 Sep 2019 09:51:54 GMT):
Is there a tutorial or sample code present which deals with private data using fabric-sdk-py? When I try to use `test/fixtures/chaincode/src/github.com/marbles_cc_private` with `collections_config` set to `https://github.com/hyperledger/fabric-samples/blob/release-1.4/chaincode/marbles02_private/collections_config.json`, I face errors like
```File "/home/student/fabric/fabric-sdk-py/hfc/fabric/channel/channel.py", line 520, in _check_policy
raise Exception('Invalid policy, missing'
Exception: Invalid policy, missing the "identities" property
```
BlackPantherIX (Tue, 24 Sep 2019 14:26:30 GMT):

BlackPantherIX (Tue, 24 Sep 2019 14:33:52 GMT):
Hi,
I want to use Hyperledger Fabric and especially Hyperledger Fabric Python SDK to run a prototype of a little blockchain use-case for my diploma.
BUT I'm not able to make at least the sample from the tutorial work. I just run out of ideas, what I can try to do.
Is there any better documentation or sample of the usage of the SDK?
Thank you for your help.
baohua (Wed, 25 Sep 2019 04:56:29 GMT):
@GuillaumeCisco @dexhunter @wangdong anything to discuss this week? Next week should be the holidays in China.
GuillaumeCisco (Wed, 25 Sep 2019 12:44:11 GMT):
no
GuillaumeCisco (Wed, 25 Sep 2019 12:44:27 GMT):
I will soon update the tutorial
baohua (Wed, 25 Sep 2019 16:21:44 GMT):
OK, then we will cancel.
baohua (Wed, 25 Sep 2019 16:22:23 GMT):
@here the hyperledger community will migrate from the gerrit CI to the github one. Please pay attention to the latest progress at #cicd channel.
Kelvin_Moutet (Wed, 25 Sep 2019 18:01:34 GMT):
@baohua Does the repo will moove also from gerrit to github ?
Kelvin_Moutet (Wed, 25 Sep 2019 18:01:34 GMT):
@baohua Does the repo will move also from gerrit to github ?

@baohua Does the repo will move also from gerrit to github too ?
baohua (Wed, 25 Sep 2019 21:12:27 GMT):
I think so. currently it automatically mirror the code from gerrit to github. After the migration, it will be pushed into github repo directly.
madhukar_sh (Thu, 26 Sep 2019 02:19:30 GMT):
Any documentation on how to create index (couchdb) using fabric-sdk-py
madhukar_sh (Thu, 26 Sep 2019 02:26:05 GMT):
somebody asked a couple of days ago as well.. any response for the same?
baohua (Thu, 26 Sep 2019 02:28:51 GMT):
Do not think there's special support of it. Have you found in other SDK?
madhukar_sh (Thu, 26 Sep 2019 02:31:53 GMT):
Fabric documentation says there is this directory structure follow: https://hyperledger-fabric.readthedocs.io/en/release-1.4/couchdb_tutorial.html#add-the-index-to-your-chaincode-folder
madhukar_sh (Thu, 26 Sep 2019 02:32:25 GMT):
And Fabric NodeSDK has a page where it talks about the same: https://fabric-sdk-node.github.io/tutorial-metadata-chaincode.html
dexhunter (Thu, 26 Sep 2019 03:00:16 GMT):
@here We will cancel this week's meeting, please sync offline, thank you!
baohua (Thu, 26 Sep 2019 04:29:53 GMT):
Thanks!
baohua (Thu, 26 Sep 2019 04:31:15 GMT):
I think you can put the index as indicated, the sdk will treat the path as the chaincode package, no matter there's index or not.
madhukar_sh (Thu, 26 Sep 2019 04:58:39 GMT):
Let me try it out today..
GuillaumeCisco (Thu, 26 Sep 2019 13:35:57 GMT):
https://gerrit.hyperledger.org/r/#/c/fabric-sdk-py/+/33771
GuillaumeCisco (Thu, 26 Sep 2019 13:36:04 GMT):

BlackPantherIX (Thu, 26 Sep 2019 15:23:01 GMT):
Thanks, I hope it'll come in time.
GuillaumeCisco (Thu, 26 Sep 2019 15:23:41 GMT):

GuillaumeCisco (Thu, 26 Sep 2019 15:23:41 GMT):
start by telling us where it fails on the tutorial
BlackPantherIX (Fri, 27 Sep 2019 11:30:49 GMT):
First of all I don't know exactly where I need to store / start my python app. Can I start it from anywhere or do I need to store it in the docker image of the sdk?
BlackPantherIX (Fri, 27 Sep 2019 11:39:38 GMT):
And on executing the sample.py from the sdk docs I'm encountering many errors like this:
sample.py:43: RuntimeWarning: coroutine 'Client.channel_create' was never awaited
GuillaumeCisco (Fri, 27 Sep 2019 12:12:05 GMT):
ok
GuillaumeCisco (Fri, 27 Sep 2019 12:12:14 GMT):
give me a little context
GuillaumeCisco (Fri, 27 Sep 2019 12:12:44 GMT):
are you a beginner, intermediate or expert in python?
GuillaumeCisco (Fri, 27 Sep 2019 12:12:57 GMT):
you have issues with asynchronous process
GuillaumeCisco (Fri, 27 Sep 2019 12:13:23 GMT):
there is no dockerimage of the sdk, so don't understand what you are trying to achieve
GuillaumeCisco (Fri, 27 Sep 2019 12:13:23 GMT):
there is no docker image of the sdk, so I don't understand what you are trying to achieve
BlackPantherIX (Fri, 27 Sep 2019 12:13:46 GMT):
I'd say intermediate.
BlackPantherIX (Fri, 27 Sep 2019 12:14:33 GMT):
But in the tutorial there's a line what tells me to make an image.
https://github.com/hyperledger/fabric-sdk-py#generating-docker-images
BlackPantherIX (Fri, 27 Sep 2019 12:15:16 GMT):
And I have it running and tried to start the sample.py from this container. But there had been no difference.
BlackPantherIX (Fri, 27 Sep 2019 12:16:32 GMT):
I'm pretty sure I've missed a thing between starting a fabric network and using it via a python script (and the sdk in between)
GuillaumeCisco (Fri, 27 Sep 2019 12:17:52 GMT):
this is not the tutorial
GuillaumeCisco (Fri, 27 Sep 2019 12:18:05 GMT):
tutorial is here : https://github.com/hyperledger/fabric-sdk-py/blob/master/docs/tutorial.md
GuillaumeCisco (Fri, 27 Sep 2019 12:18:19 GMT):
why are you trying to build images?
BlackPantherIX (Fri, 27 Sep 2019 12:19:17 GMT):
I thought I need a running container of the sdk which handles the function calls of my python script.
BlackPantherIX (Fri, 27 Sep 2019 12:20:21 GMT):
And yes, I'd been going through all the steps from the tutorial you've mentioned.
GuillaumeCisco (Fri, 27 Sep 2019 12:20:23 GMT):
sdk is like all others sdk, simply import it
baohua (Fri, 27 Sep 2019 18:36:12 GMT):
+2!
madhukar_sh (Sat, 28 Sep 2019 02:26:46 GMT):
Our tutorial is fine, When I started - It was good enough to strat and get going..
Where we lack is a documentation / a reference index of what all functions are available in the SDK.
For example createUser function of the CAService -> I never knew it existed until someone here mentioned when i asked over chat.. It would be great to have some SDK/APi reference where possible functionalities are listed
madhukar_sh (Sat, 28 Sep 2019 02:26:46 GMT):

madhukar_sh (Sat, 28 Sep 2019 02:27:24 GMT):
Any idea what may be causing this error?
```txEvents = self.evts[self.evt_tx_id]['txEvents']
KeyError: 'txEvents'
Task exception was never retrieved```
madhukar_sh (Sat, 28 Sep 2019 02:34:57 GMT):
Error is from here:
``` Line 1726, hfc/fabric/client.py
# check if all tx are valids
txEvents = self.evts[self.evt_tx_id]['txEvents']
statuses = [x['tx_status'] for x in txEvents]
if not all([x == 'VALID' for x in statuses]):
raise Exception(statuses)```
Is it because there are no transaction events?
Wondering how can transaction_id exist if there were no tx events
GuillaumeCisco (Mon, 30 Sep 2019 08:48:25 GMT):
would be great
GuillaumeCisco (Mon, 30 Sep 2019 08:49:06 GMT):
Interesting @madhukar_sh I wonder how you succeeded triggering this error. Do you know how to reproduce that?
GuillaumeCisco (Mon, 30 Sep 2019 08:51:08 GMT):
`txEvents` is populated here: https://github.com/hyperledger/fabric-sdk-py/blob/master/hfc/fabric/client.py#L1246
GuillaumeCisco (Mon, 30 Sep 2019 08:51:24 GMT):
it looks like the chaincode tx event never received it
GuillaumeCisco (Mon, 30 Sep 2019 09:16:05 GMT):
it can be done here too: https://github.com/hyperledger/fabric-sdk-py/blob/master/hfc/fabric/client.py#L1194

GuillaumeCisco (Fri, 04 Oct 2019 07:58:31 GMT):
Hum first of all @mikeyangyo you are not placing your cert files in the right directories. Private key should be in keystore, cert should be in signcerts, ca-cert should be in cacerts as described here https://hyperledger-fabric.readthedocs.io/en/release-1.4/msp.html#msp-setup-on-the-peer-orderer-side

and i need to generate the command for my app, so i think i need to use ca the generate them
mikeyangyo (Sun, 06 Oct 2019 06:08:17 GMT):
and if i use `openssl -x509 --noout --text --in path_to_cert`, how to know my cert files are correct

hengfun (Wed, 30 Oct 2019 14:41:08 GMT):
@dexhunter Sounds good, when is the meeting?
hengfun (Wed, 30 Oct 2019 14:44:03 GMT):
@GuillaumeCisco Yes, he's has a lab in University of Bern, https://crypto.unibe.ch/. Christian is very responsive, I emailed him for projects and he responded. here is his contact cachin@inf.unibe.ch
GuillaumeCisco (Wed, 30 Oct 2019 14:46:12 GMT):
Thanks a lot
dexhunter (Wed, 30 Oct 2019 14:51:07 GMT):
@hengfun you can check previous wiki about the time https://wiki.hyperledger.org/display/fabric/2019-08-29, in China it's 9pm(UTC+8) Thursday night, for Switzerland should be 2pm(UTC+1)
dexhunter (Wed, 30 Oct 2019 14:53:55 GMT):
@hengfun So are you available during this time? I'll send notification accordingly, thanks!
hengfun (Wed, 30 Oct 2019 14:57:01 GMT):
@dexhunter I'm currently based in Seattle, this seems to be at 6am, It's a little early but I can make it. When is the next meeting?
dexhunter (Wed, 30 Oct 2019 14:58:37 GMT):
oh, I see. That's very early for you then XD. We can do it tomorrow or we can wait for @GuillaumeCisco and have meeting in next week.
GuillaumeCisco (Wed, 30 Oct 2019 14:59:48 GMT):
I'm on UTC+!, living in France :)
GuillaumeCisco (Wed, 30 Oct 2019 14:59:48 GMT):
I'm on UTC+1, living in France :)
GuillaumeCisco (Wed, 30 Oct 2019 15:00:59 GMT):
I can be available tomorrow, but I have nothing new to talk except a little thing :)
dexhunter (Wed, 30 Oct 2019 15:01:49 GMT):
ok, then. So I think tomorrow is good, I also don't have much to talk about but I am very happy to hear from @hengfun about his project =)
dexhunter (Wed, 30 Oct 2019 15:06:57 GMT):
@here Dear all, we will have meeting 9PM this Thursday evening, pls help update the agenda at https://wiki.hyperledger.org/display/fabric/2019-10-31 welcome to attend, thanks!
hengfun (Wed, 30 Oct 2019 15:22:27 GMT):
Hi do you mind if we push it back 1 hour? It will give me some time to prepare, also worried I might not wake up in time :sweat_smile:
dexhunter (Wed, 30 Oct 2019 15:23:48 GMT):
need to consult with @baohua since I am not sure whether there will be another meeting going around that time
hengfun (Wed, 30 Oct 2019 15:24:14 GMT):
If not I can make it
dexhunter (Wed, 30 Oct 2019 16:06:10 GMT):
@here ok, after consulting with @baohua we decided to make a change for the meeting time of this week which works better for @hengfun. So for this week, the meeting time will be 9am(UTC+8) 6pm(UTC-7) 2am(UTC+1) https://wiki.hyperledger.org/display/fabric/2019-11-01

Hi like to decentralize cli on a different machine from the one of the node. Since the cli machine can’t run nodejs we are trying to create a custom cli with python sdk to enroll and use the cli. We managed to install the hfc.fabric module running with Python3.6.8 but we have issues we try to instantiate the Client object passing the network configuration json: maybe the network json we are using is not suitable for this sdk but for node js sdk and java sdk it does work.
This is the snippet of the error
from hfc.fabric import Client
cli = Client(net_profile="network.json")

So starting from the previous question:
1) what python version should i use? Is 3.6.8 the correct one? The ONLY correct one?
2) Is adding orderer enough to use the connection profile? ccp-template (byfn) seems to not have just peers, and ca.

Hi @giuzero sorry but I am unable to look at your case right now because I am busy on catching the deadline for my paper and assignments. Maybe you can have a look at [our tutorial](https://github.com/hyperledger/fabric-sdk-py/blob/master/docs/tutorial.md#122-get-credentail-from-fabric-ca)? I hope this helps. Or maybe others will come and help later. Thanks

@dexhunter yes, I already tried with the tutorial, no luck. With HLF 1.4.0 1.4.3 and 1.4.4. Cli is on a x86 32bit system.
giuzero (Thu, 28 Nov 2019 09:36:07 GMT):

tongli (Thu, 05 Dec 2019 16:34:06 GMT):
it seems to me that the event listener is not getting the payload for chaincode event.
tongli (Thu, 05 Dec 2019 16:34:29 GMT):
can anyone confirm that is the case or not?
tongli (Fri, 06 Dec 2019 02:48:10 GMT):
@dexhunter thanks for reviewing the pr. can you please merge it? or this has to be done by Ry?
wangdong (Fri, 06 Dec 2019 07:54:31 GMT):
@tongli thanks for the PR.
wangdong (Fri, 06 Dec 2019 08:07:06 GMT):
I think so. @tongli . This is missing feature now.
dexhunter (Fri, 06 Dec 2019 08:46:46 GMT):
hi, normally we need 2 reviewers reviewed the change before merging. So now it has been merged by @baohua. Thank you for your contribution!

How could we fix that?
dexhunter (Sat, 07 Dec 2019 13:08:54 GMT):
I think you need to first fork the project then submit PR to the main one
GuillaumeCisco (Sat, 07 Dec 2019 13:38:41 GMT):
hum, you're right, it seems like I cannot directly push to the main project
GuillaumeCisco (Sat, 07 Dec 2019 13:41:38 GMT):
just submitted a new one ;) https://github.com/hyperledger/fabric-sdk-py/pull/10
giuzero (Tue, 10 Dec 2019 09:21:00 GMT):
Hi guys, how can i enroll, register and invoke chaincode? I'm still blocked here https://chat.hyperledger.org/channel/fabric-sdk-py?msg=yGsLJLt5m67Wt5pyi
GuillaumeCisco (Wed, 11 Dec 2019 07:08:19 GMT):
We need more information about your setup and your code @giuzero If you are looking for something working, please look at https://github.com/SubstraFoundation/hlf-k8s and https://github.com/SubstraFoundation/substra-backend you will see working examples
giuzero (Wed, 11 Dec 2019 10:09:18 GMT):
Hi @GuillaumeCisco here is a snippet https://chat.hyperledger.org/channel/fabric-sdk-py?msg=rvbppCDxYPjmngHkF
I'll have a look on substra. Thanks for you reply.
GuillaumeCisco (Wed, 11 Dec 2019 10:14:40 GMT):
this is clear
GuillaumeCisco (Wed, 11 Dec 2019 10:14:44 GMT):
csr.public_bytes(Encoding.PEM).decode('utf-8'),
AttributeError: 'str' object has no attribute 'public_bytes'
GuillaumeCisco (Wed, 11 Dec 2019 10:15:02 GMT):
csr is a str here, but should be a csr object
GuillaumeCisco (Wed, 11 Dec 2019 10:16:45 GMT):
You are passing certificate authority to the csr parameter
GuillaumeCisco (Wed, 11 Dec 2019 10:17:27 GMT):
csr stands for Certificate Signing Request
GuillaumeCisco (Wed, 11 Dec 2019 10:17:35 GMT):
https://cryptography.io/en/latest/x509/reference/#x-509-csr-certificate-signing-request-object
GuillaumeCisco (Wed, 11 Dec 2019 10:17:43 GMT):
This is not the same thing
GuillaumeCisco (Wed, 11 Dec 2019 10:19:33 GMT):
see this example: https://github.com/SubstraFoundation/hlf-k8s/blob/11cd70b744348e33778b3ee99157bc4137ad8df0/python-scripts/utils/setup_utils.py#L211
GuillaumeCisco (Wed, 11 Dec 2019 10:20:04 GMT):
you need to put your test.pem to this call: ca_cli = ca_service(target="https://" + CA_SOLO)
GuillaumeCisco (Wed, 11 Dec 2019 10:20:31 GMT):
like this: cacli = ca_service(target=target,
ca_certs_path=org['ca']['certfile']['internal'],
ca_name=org['ca']['name'])
GuillaumeCisco (Wed, 11 Dec 2019 10:21:14 GMT):
furthermore, you need to pass a path, not directly the cert, in your case, this will be: os.path.join(os.path.dirname(__file__),
"resources/ca.org1.example.com-cert.pem"
giuzero (Wed, 11 Dec 2019 10:21:47 GMT):
Ok I followed 1.2.2 Get Credentail from Fabric CA on https://github.com/hyperledger/fabric-sdk-py/blob/master/docs/tutorial.md , I'll try your solution as soon as possible, many thanks.

GuillaumeCisco (Wed, 11 Dec 2019 10:30:03 GMT):
you can also check the node js documentation: https://fabric-sdk-node.github.io/release-1.4/FabricCAServices.html#enroll
giuzero (Wed, 11 Dec 2019 10:40:44 GMT):
Yes, Nodejs SDK works without any problem, in fact I'm using it on other projects. I need to work with py sdk because my cli target is a x86.
giuzero (Wed, 11 Dec 2019 10:45:42 GMT):
tried already os.path.join(os.path.dirname(__file__),

giuzero (Wed, 11 Dec 2019 10:46:42 GMT):
could it be date not synchronized between the two machine?
GuillaumeCisco (Wed, 11 Dec 2019 10:49:16 GMT):

GuillaumeCisco (Wed, 11 Dec 2019 10:49:33 GMT):

@GuillaumeCisco gosdk can deal with the dynamic service discovery, pysdk lacks in that regard. Will you add that function?
GuillaumeCisco (Tue, 17 Dec 2019 15:11:21 GMT):
there is a discovery method in fabric sdk py
GuillaumeCisco (Tue, 17 Dec 2019 15:11:26 GMT):
we use it in production
GuillaumeCisco (Tue, 17 Dec 2019 15:21:12 GMT):
you can see an implementation here: https://github.com/SubstraFoundation/substra-backend/blob/39f4eb0e8d6ac9d5f0bfaef8f7685e6166963e8e/backend/backend/settings/deps/ledger.py#L93
tongli (Tue, 17 Dec 2019 16:50:00 GMT):
@GuillaumeCisco so channel._discovery will return a set of peers? what I am looking for is a set of peers available based on the channel endosement policy.
tongli (Tue, 17 Dec 2019 16:50:56 GMT):
for example, if there are 5 peers belong to 3 orgs, the endorsement policy say requires marjority, then the function should return 2 peers to send proposals to.
tongli (Tue, 17 Dec 2019 16:51:12 GMT):
not all 5 peers. that is really something I am looking for.
tongli (Tue, 17 Dec 2019 16:51:47 GMT):
seems to me that the _discovery function will just return available peers, not necessarily has anything to do with endorsement policy.
GuillaumeCisco (Tue, 17 Dec 2019 17:02:17 GMT):
the _discovery method is part of the discovery api, this is just a PORT
GuillaumeCisco (Tue, 17 Dec 2019 17:02:17 GMT):
the _discovery method is part of the discovery api, this is just a portable way to access this API
GuillaumeCisco (Tue, 17 Dec 2019 17:02:39 GMT):
You have to handle the rest
dexhunter (Wed, 18 Dec 2019 05:39:55 GMT):
@here We will cancel this week's meeting due to low profile. Let us sync offline, thanks!
tongli (Thu, 19 Dec 2019 15:21:34 GMT):
@GuillaumeCisco can you add the event payload to the sdk? Currently when event is caught, there is no payload returned on the event object. This is rather critical. Can any of the maintainer add that function?
GuillaumeCisco (Thu, 19 Dec 2019 15:24:01 GMT):
it is added
GuillaumeCisco (Thu, 19 Dec 2019 15:24:16 GMT):
you have to pass filtered=False to your channel event hub configuration
GuillaumeCisco (Thu, 19 Dec 2019 15:24:26 GMT):
Please read carefully the documentation about that
GuillaumeCisco (Thu, 19 Dec 2019 15:25:38 GMT):
`The payload of chaincode events will not be included in filtered blocks.`

giuzero (Tue, 07 Jan 2020 10:24:36 GMT):
thank you @GuillaumeCisco , I will try it as soon as possible! From my understanding the difference is adding grpc_options into the connections profile, right? (I had /etc/hosts ready)

I'm reviewing it and think we should rebuild it from scratch
GuillaumeCisco (Fri, 31 Jan 2020 08:36:43 GMT):
We have no gateway/network process
GuillaumeCisco (Fri, 31 Jan 2020 08:36:50 GMT):

wangdong (Sat, 01 Feb 2020 04:02:18 GMT):
@baohua new release needs your approve.

I missed the permission.
dexhunter (Wed, 05 Feb 2020 06:42:24 GMT):
@GuillaumeCisco I think we can do it at a different branch, what do you think?
GuillaumeCisco (Wed, 05 Feb 2020 07:51:42 GMT):
what? A rewrite or the 2.0 support ?
GuillaumeCisco (Wed, 05 Feb 2020 07:51:42 GMT):
what? A rewrite or the 2.0 support?
dexhunter (Thu, 06 Feb 2020 08:34:26 GMT):
I think we can do both in separate branches, while from my perspective 2.0 support seems easier to do at the moment. Besides, the new round of internship/mentorship is starteing, would you like to participate as a mentor? @GuillaumeCisco

@GuillaumeCisco I think refactor to gateway/remote is do-able but after reviewing your code, I am wondering if we can make it more pythonic. (Currently it seems to plain translation from nodejs) Besides, I am proposing this year's mentor project to see if we can recruit new contributors.

@dexhunter is there plan to add cc lifecycle?
tongli (Sat, 22 Feb 2020 12:31:38 GMT):
BTW, I tried to install sdk using alpine python image, it blows up big time. Do not have the error msg now. But do any of you ever tried to install this sdk onto alpine python env? Like 3.8 alpine docker image.
tongli (Sat, 22 Feb 2020 12:32:44 GMT):
The reason why I am asking is because other flavored python docker image all so big. Alpine based is a lot smaller. But this sdk won’t install though. Dependency issues
dexhunter (Sat, 22 Feb 2020 19:38:43 GMT):
Hi, what do you mean by cc lifecycle? @tongli we do support install/instantiate/invoke/query cc, etc.
dexhunter (Sat, 22 Feb 2020 19:40:44 GMT):
Regarding Alpine python image, can you open an issue on GitHub/jira, we will have a look later. Thanks
tongli (Sat, 22 Feb 2020 23:38:42 GMT):
@dexhunter yeah, fabric 2.0 introduced new way of installing, chaincode.
tongli (Sat, 22 Feb 2020 23:39:04 GMT):
Now chaincode will also need to be approved and then committed
tongli (Sat, 22 Feb 2020 23:39:30 GMT):
This new process is called chaincode lifecycle. Used to be just install and instantiate
tongli (Sat, 22 Feb 2020 23:40:14 GMT):
Now it involves more steps. One has to package, install, approve (according to the policy), then commit
tongli (Sat, 22 Feb 2020 23:40:34 GMT):
This new process has not been supported by most of the sdk
tongli (Sat, 22 Feb 2020 23:41:35 GMT):
You can see them from new command line tool
tongli (Sat, 22 Feb 2020 23:41:54 GMT):
Used to be peer chaincode install, instantiate. Now
tongli (Sat, 22 Feb 2020 23:42:30 GMT):
Peer lifecycle install, approvebymyorg , commit etc
tongli (Sat, 22 Feb 2020 23:43:02 GMT):
Do not remember the exact syntax. You can boot up a new fabric-tools container and take a look
dexhunter (Sat, 22 Feb 2020 23:43:34 GMT):
I see. We haven't supported fabric 2.0 yet. But feel free to contribute. =)
tongli (Sat, 22 Feb 2020 23:45:06 GMT):
Yeah. I would love too but I just do not have much of time on my hands.
dexhunter (Sat, 22 Feb 2020 23:47:02 GMT):
I am thinking to refactor part of codes as well. Currently sdk does not handle well with re-connecting to the network. For example, if I close the python sdk and reopen I couldn't find previously connected peers (I guess discovery service api can do but sdk should have better implementation like channels etc.)
tongli (Sun, 23 Feb 2020 17:21:56 GMT):
@dexhunter I saw your forked repo the other day. U only considering refactor connection part or rewrite pretty much every thing?
dexhunter (Sun, 23 Feb 2020 21:10:17 GMT):
@tongli based on @GuillaumeCisco 's refactor code: https://github.com/GuillaumeCisco/fabric-sdk-py/tree/refacto
dexhunter (Sun, 23 Feb 2020 21:10:17 GMT):
@tongli The new code will be based on @GuillaumeCisco 's refactor branch: https://github.com/GuillaumeCisco/fabric-sdk-py/tree/refacto
baohua (Fri, 28 Feb 2020 00:51:44 GMT):
HLF 2.0 changed the chaincode to a new lifecycle https://hlf.readthedocs.io/en/latest/commands/peerlifecycle.html @dexhunter

Hello guys!
I've been trying to install `couchdb` on the azure pipeline instance however when I try hosting it on `localhost:5984` it always exits with ConnectionRefused error.
I suspect this is because the port isn't open...
Is there an easy fix for this?
dexhunter (Wed, 25 Mar 2020 07:07:36 GMT):
@ROHAN_SHROTHRIUM I've asked at #fabric-ci but havn't got any replies. Maybe you can try adding `sudo ufw allow 53` to `azure-pipeline.yml` to see if it works.

You don't have to modify the host system, you can use service containers and launch a CouchDB container and map the local 5984 to the container
BrettLogan (Thu, 26 Mar 2020 02:36:12 GMT):
```resources:
containers:
- container: couchdb

couchdb: couchdb```

Following this doc though: https://github.com/apache/couchdb-pkg/blob/master/README-SNAP.md

Works
BrettLogan (Thu, 26 Mar 2020 03:18:37 GMT):
``` steps:
- script: |
sudo snap install couchdb
sudo snap set couchdb admin=admin
sudo snap start couchdb
sudo snap connect couchdb:mount-observe
sudo snap connect couchdb:process-control
- script: sleep 5
- script: curl localhost:5984```
BrettLogan (Thu, 26 Mar 2020 03:18:55 GMT):
You do have to sleep for 5 seconds before curling to give couch some time to start
BrettLogan (Thu, 26 Mar 2020 03:19:33 GMT):
I confirmed I could recreate you problem by just doing a snap install and then trying to curl. But following the doc to the letter works

Hey everyone! I'm new to the Fabric Python SDK community and I've recently had the experience of implementing a mock network using the SDK. One of the more frustrating experiences I've had is trying to interpret the Python functions and understand their input requirements and output objects. I would like to go ahead and add a task to myself to expand the function docstrings and add type hinting per PEP 484. Would this be a worthwhile or appreciated task for me to do? I wanted to get some feedback from you all before I rushed in to it.
dexhunter (Wed, 13 May 2020 08:52:11 GMT):
@codyjgilbert that would be great!

I'll also help along the way. So if there are problems, feel free to contact me or through the issue (which I will respond fast when I receive the notification)

Hi everyone, I've been looking into python sdk and noticed that it has hardcoded `CC_TYPE_GOLANG` in `chaincode_install` function. Is there a jira ticket or something about that?
dexhunter (Thu, 14 May 2020 09:45:19 GMT):
@nkalichynskyi you can report on github issue, but for now most people just use golang to write chaincodes, but if you want to use other languages such as nodejs you can make the modification
nkalichynskyi (Thu, 14 May 2020 11:04:20 GMT):

Kelvin_Moutet (Thu, 09 Jul 2020 11:58:52 GMT):
But I have questions :
- When a new release of fabric-sdk-py will be released (last version was last year https://github.com/hyperledger/fabric-sdk-py/releases/tag/v0.8.1 )?
- Does someone test it on hyperledger 2.x ?
baohua (Thu, 09 Jul 2020 17:47:06 GMT):
2.x support is planed after we enhance the docs and sample code. And there's plan a new release as the latest support version of v1.4.x.

Hi everyone, I'm having an issue with fetch of the config block for system channel, for some reason when fetching config block using python sdk config part /channel_group/groups/Orderer/values/ConsensusType/value doesn't have metadata/consenters field. It seems to be an issue with protobuf decoding because if I fetch application channel config without decoding everything is in place, but get_channel_config_with_orderer doesn't allow fetch of the system channel config without decoding. Can anyone comment on this if this is known issue or maybe I'm doing something wrong?

Our team uses this SDK, contributed to it and willing to contribute further, but looking at recent github activity we are not sure if this would be a wise investment of our time.
Can somebody answer if there are plans to develop this SDK further? It has already been more than a year since release of fabric v2 and introduction of new chaincode lifecycle although still no support for it in this SDK.

Hi, error seems to be pretty clear in stating that chaincode with the same name and version already exists. You might have installed it in some previous run of the script without realizing it. You now can proceed to the next steps in tutorial or change version and try to install it again with different version value if you still want to install it.

Hi there! I'm trying to integrate the Flower framework (for Federated Learning) with Hyperledger Fabric, and I'm using the Python SDK. However, I am unable to publish the Machine Learning models on the Blockchain. They are simply lists of numerical values. I don't understand if it's a payload size issue (models are composed of many values, the size I think is around 40MiB) or something else. However using the JavaScript SDK everything works. Does anyone have any ideas? Thanks in advance
