Minor updates on Pike can fail with "socket is already closed"

[Jiří Stránský]

Quite a confusing output from a failed update, probably due to Zaqar messaging issues:

 u' "stdout: Trying to pull repository 192.168.24.1:8787/rhosp12/openstack-gnocchi-metricd ... ", ',
 u' "2018-03-19.3: Pulling from 192.168.24.1:8787/rhosp12/openstack-gnocchi-metricd", ',
 u' "9a32f102e677: Already exists", ',
 u' "b8aa42cec17Waiting for messages on queue 'f813b1b0-41bb-411f-abb9-c1f3bd3541d6' with no timeout.
socket is already closed.

Where is this output coming from?

The 'socket is already' closed sounds like a UI error message.

Minor update CLI, `openstack overcloud update run`. The current intended fix is this backport

...to be tested.

    Get message from websocket instead from zaqarclient directly

    Use the websocket api to get and print the real time
    ansible execution for minor update instead of using the
    zaqarclient call directly.
    This is safer and avoid brutal claim of the messages.

    Manual conflict resolution on:
    tripleoclient/workflows/package_update.py

Change abandoned by Jiri Stransky (<email address hidden>) on branch: stable/pike
Review: https://review.openstack.org/559738
Reason: Not needed anymore, it was fixed by backporting different approach to the message fetching

[OpenStack Infra (hudson-openstack)]

This issue was fixed in the openstack/python-tripleoclient 7.3.10 release.
