koji watcher taglist

[Kamil Paral]

Hello,

currently the watched taglist for koji watcher looks like this:

taglist = set(('dist-f10-updates-candidate',
               'dist-f11-updates-candidate',
               'dist-f12-updates-candidate',
))

I'm new to Koji, but I have discussed these things with Daniel
Mach and I think the current koji watcher implementation isn't right.
The problem is that the dist-fxx-updates-candidate tag is valid
for only a while. After that it is changed to dist-fxx-updates
tag (build goes directly to stable updates) or it is changed to
dist-fxx-updates-testing (build goes to testing updates). If we
have not detected that new build in the meantime, we have lost
that information and won't know about it anymore.

One solution is to check all new builds for dist-fxx-updates-candidate,
dist-fxx-updates-testing and dist-fxx-updates tags.

Another (better) solution is to check for all new builds and
filter for only those packages, which have dist-fxx-updates-candidate
tag in *their history* (not necessarily as current tag, which
does current implementation). To see the concept have a look at:
$ koji list-tag-history --build wormux-0.8.3-1.fc11

There is certainly some API to achieve that. Will, if you want,
I can try to provide a patch for that.


Daniel also suggested a few alternative mechanisms for new build
notification. If our tests would be quick, we could modify koji
tasks (example here:
http://koji.fedoraproject.org/koji/taskinfo?taskID=1789344 )
and add a Descendant Task to test the package.
If our tests would take longer (which I assume in the longer run)
we could modify the koji tasks and add at least a notification
to our autoqa server that a new build has been done. This way
we wouldn't have to query periodically but we would be notified
immediately.

That was just a remark about alternative notification method.
The important issue was the first one.
