I do not agree that release milestones are helpful for this category of
bugs. The majority of stable point releases will have zero issues in a
release milestone. Opening/closing empty milestones all the time is a
lot of busy work.
Milestones are helpful for *initial* releases of stable branches, not
point releases. Even for initial releases important use cases for
milestones are not supported by gitlab. As an example, we may be able
to verify that a specific test is regressed with an A/B test of the
previous release -- and perhaps identify the commit that regressed it.
How can we find if an issue exists for this test? You cannot:
- search for issues mentioning a test name (unless it is in the title)
- search for issues mentioning a commit
- subscribe to issue comments in a way that would let you search
How can we audit new issues for items that have not been triaged since
the last release? The only workflow that I can imagine is to sort all
issues by "last updated" and read through every open issue changed in
the past 3 months. Of course, the list changes as you read through it.
I'm contrasting this with Bugzilla, where we could subscribe to bug
comments and read through them on a daily basis. At release time, I
could have confidence that I had seen all bugs that might affect end
The labels "bisected" and "regression" serve as a good indicator of bugs
that should block release, assuming someone has by chance applied the
labels correctly. For point releases, adding a "stable" label may tell
us when an issue blocks point releases as well. Any issue related to a
commit that CC's stable would get this label. Personally I think this
label will not solve the problems either, because it requires careful
monitoring of issues to notice regressions which cc stable.
The information needed to *automate verification* of stable releases
exists, within gitlab and the git log. However, a sane and robust
release process cannot be implemented on top of gitlab's pitiful search
