Hey there,
Matthias announced that F would have python3.8 and from the recent
upload, it looks like that's being worked on actively at the moment.
Yes. To be clear, "F would have python3.8 (at archive opening)" means having python3.8 as a supported version, not just having 3.8 available (eoan has 3.8 available).
While looking at the update_excuses_by_team.html#desktop-packages report
I noticed some delta-over-debian being added to packages where I
can't really make sense of what's going on in the changelog.
Some examples
http://launchpadlibrarian.net/447713946/pygobject_3.34.0-1build1_3.34.0-1ubuntu1.diff.gz
http://launchpadlibrarian.net/447727952/pycairo_1.16.2-1ubuntu1_1.16.2-1ubuntu3.diff.gz
http://launchpadlibrarian.net/447772089/cracklib2_2.9.6-2build1_2.9.6-2ubuntu1.diff.gz
Some changes for example add a Build-Depends on dh-exec and hacks in the
.install, I guess those doing the changes understand why but it triggers
some questions to me
- Could someone explain why those .install tricks are needed exactly?
It's because the "abi tag" for python c extensions has changed in a way that makes it a bit annoying / impossible to write a glob that matches 3.7 and 3.8 release build extensions and not the debug extensions.
Couldn't the issue be solved in the python packaging tools instead?
Yes, probably.
- Can/should those changes be forwarded to Debian? (they are not at the
moment?) I would be happy to help with that once I understand the
technical approach being taken.
I've made a bug report for cracklib2 now.
- Is that a transition we are under pressure to get through?
Well we want it to complete before opening the archive and I assume people want the archive to open...
Should we
maybe take the time to document what's going on
Well there was this mail: https://www.mail-archive.com/ubuntu-devel@lists.ubuntu.com/msg09144.html
And there is a transition tracker: https://people.canonical.com/~ubuntu-archive/transitions/html/python3.8-add.html (not sure this has been advertised but it's not hard to find).
and have more people
helping and do things in a way were we collectively understand what is
happening
Maybe roping in more people would help, maybe not. The plan was for Matthias and I to work on this more or less full time and just crank through it.
so we know what to do from those deltas in the futur/ help
forwarding to Debian for example?
While in general we should certainly forward things to Debian I do think the people who end up doing this transition in Debian in general know to look for potential fixes in Ubuntu (when the changes will presumably make more sense if those people are diagnosing the same or similar build failures). And some of them may not be necessary, if like you say dh-python can grow smarts to make installing the right extensions into the right packages more easily.
Cheers,
mwh
