Hi all,
As you know, the 5.9 freeze is coming up and should happen on the 18th
of July.
This release will be a special one since, as of yesterday¹, all
critical tests pass on our Windows Python 3 Heptapod CI. Tests related
to extensions (like SVN support, `remotefilelog`, etc.) still have to
be worked on and there is minor flakyness with a few tests², but the
message is: I vote that this be the first release to support Python 3
Windows officially and the last to support Python 2 altogether. This
will give us enough time to iron out the details in time for the 6.0
release to be the first Python 3 only release of Mercurial.
For the past few versions we haven't had much of a real freeze, which
I think makes sense given the volume of contributions and the
relatively good track-record of (lack of) regressions, but this time I
want to propose that we observe a real freeze to dedicate at least
some time to fixing the issues we're having and stabilizing the new
stuff.
To name some things explicitly:
- The parent ordering issue³ which is almost 50% why I'm advocating
for the freeze⁴
- Windows Python 3 support and improving CI coverage
- `chg` now almost consistently times out some tests
- `test-chg.t` is super flaky because of `sleep` calls
- Bugs that have began building a settlement in bugzilla
I, for one, am happy that the end of the Py2 era is finally visible at
the end of the tunnel and would like to thank all involved in the
recent Windows endeavor.
Lastly, the Heptapod Windows CI Octobus is providing for this
transition will cost about 400€ per month. We're currently running on
free credit we have thanks to a partnership with OVH given for use in
the Heptapod project, but this will run out one day and we very much
encourage those who can help to reach out. Octobus is a 5-people
European team already funding the development of Heptapod out of
pocket, and there is only so much that can be reasonable for us to
shoulder in the long-run.
What are your thoughts?
