Thanks a lot for your work. Actually this is a vendor package and we have no plan to main the code of this part. I am afraid we cannot merge this. @idealhack
And much other work are appreciated. 😄 🍻

I think here comes a flaky test, @fuweid :

@allencloud I see, but why there are different folders for vendor packages?

I see, but why there are different folders for vendor packages?

This is a good question. Lots of things have been discussed before, like:
#1344
#428
#750

I think we do need to take into vendor the latest version into consideration. WDYT? @rudyfly

[fuweid]

@allencloud This is not flaky case. The pouchd cannot remove the running task. We are still investigating the issue.

[idealhack]

I'll keep this open for now. Feel free to close it when you open new ones for the ci and dependency issues.

[allencloud]

Could you help to vendor the latest libnetwork package with govendor tool? @idealhack
I think this is what we wish to finish. We encourage you to finish it very much and feel free to tell us if you have any problem when doing this.

[idealhack]

Since #1344 is open, let's resolve the dependency issue in that thread.

Feel free to close this one when you open a new one for the ci issue.

Thanks @idealhack
While I do not think this issue could help. And I am closing it.
