Zuul CI status now displayed on Gerrit changes - Wikitech-l

24 Mar 2023


      Hello,
I have deployed a change to Gerrit which makes it display the ongoing 
CI/Zuul build if there is any.
If Jenkins jobs are running, you would see below the commit message some 
gray chipset with the name of the Zuul pipeline (test, gate-and-submit 
..). The Check tab shows the jobs details 
(https://phabricator.wikimedia.org/F36925186).
By exposing the Zuul CI status directly in the Gerrit web UI, people 
will notice a build error earlier. That also saves the hassle of having 
to monitor https://integration.wikimedia.org/zuul/.
There are a few glitches:
* the way I have implemented it abuses the model proposed by Gerrit
    and in progress jobs are always considered a SUCCESS but will be
    marked as ERROR when they fail.
  * code is entirely running in the client browser. It is unable to send
    notifications or triggers any email when a build has failed. The
    EarlyWarning bot by Kosta Harlan
    https://phabricator.wikimedia.org/J302 does it though)
  * I am not a JavaScript developer per see but learned about TypeScript
    for static analysis and rediscovered QUnit. So at least there are
    some basic guarantees.
  * there are surely a bunch of edge cases that I have not properly handled
The code for those that are curious is at

If you see problems, JavaScript errors etc please paste them on 
https://phabricator.wikimedia.org/T214068 :)
