Python 3.7 or 3.6 in Buster
Hi there! During Debconf, we decided we would not decide yet, and see in November if we think it's reasonable to allow Python 3.7 to reach Buster. Time has passed, RC bugs have been fixed, and now is probably the time to open this thread. To me, as much as the OpenStack packages are concerned, I'm kind of fine with 3.7, modulo fixing this bug in Glance: https://bugs.debian.org/911947 which I forwarded here: https://bugs.launchpad.net/glance/+bug/1800601 It looks like this bug is 3.7.1 specific (ie: there's no bug if using Python 3.7.0). Upstream had a look, and didn't find a way to fix (yet). Help appreciated. It looks like everything else in OpenStack works. What is the situation for other packages? Do we have lots of Python 3.7 problems remaining? If so, it'd be nice to have them listed somewhere, so we have a clear picture of what's going on. Do other fellow DD also think it's kind of ok to keep 3.7 in Buster? Also, Doko, do you plan on upgrading to newer point release? Python 3.7.1-rc1 and 3.7.1 both were the cause of troubles for me. I just hope this wont happen again (though I'd understand if you wished to upgrade once more before the freeze). In any ways, it'd be nice to communicate what you're planning on doing. Cheers, Thomas Goirand (zigo)

I'm > trying to remember to attach all my patches to Debian bug reports... in Ubuntu, we were able to migrate it (equivalent to the unstable -> testing migration) with 3.7 as the default. We are in progress removing 3.6 as supported, which exposed some autopkg test regressions which are currently worked on.

I'm in favor of going with 3.7, and would like to update to the current 3.7 release branch at freeze, and then to 3.7.2 later, expected in January. Matthias

I recently got burned by changes in the way re.sub works in python3.7 (see [1]
and search for re.sub, [2], and [3]). From the whatsnew:
> re.sub() now replaces empty matches adjacent to a previous non-empty match.

This change broke canonicalization in dkimpy. Once I knew about it, I fixed
it, but the default 'import foo' autopkgtests we have on so many modules won't
find this (I don't think, it didn't in my case).
I only found out about it due to an upstream bug report on OS X. No one in
Debian (or Ubuntu) reported it.
Does anyone have an idea about how common problems from this change might be?
That particular package uses re.sub 8 times and only one use was problematic.
In any case, I don't have anything other than a vague concern based on one of
my packages that there are more hidden problems.

I got one also in fabio: https://github.com/silx-kit/fabio/pull/243 Actually there has been a depreciation warning for ages (back to python 3.4) but this has been silenced since then. There may be many such bugs around in many packages! Cheers, Jerome

Thanks. Related, but not the same. There was no deprecation warning for re.sub like there was for re.split. In any case, it reinforces my concern. Scott K
