Updating Perl to 5.23?

Updating Perl to 5.23?

[Ludovic Courtès]

In ‘core-updates’ I want to fix a couple of non-determinism issues
related to Perl:

  https://bugs.debian.org/801621
  https://bugs.debian.org/801523

While at it, I thought we might as well upgrade Perl to 5.23.

What do people think?  I have no experience with Perl, so I’m not sure
whether this is a minor upgrade, or if it would break lots of things.

Thanks,
Ludo’.

According to <http://www.cpan.org/src/README.html>,
perl uses the version scheme such that maintenance branches (ready for
production use) are even numbers and development branches are odd
numbers. Thus, 5.23 is a development branch. From this page
<https://packages.debian.org/experimental/perl>, it seems Debian only
packages maintenance branches. Perhaps it is too risky to package
development branches (break a lot of things). How do you guys think?

In terms of large updates, pkg-config is up to 0.29, python just hit 3.5, and
python2 hit 2.7.11. Although in relation to odd numbers being dev releases, I
don't know about any of the above version changes if they're dev releases or
not.

You’re welcome to try these updates in ‘core-updates’.  Note however
that testing them requires a lot of rebuilds on your side, but hey,
that has to be done anyway!  :-)

Very good point.  So I guess we’d be targeting 5.22.  Does the
5.16 → 5.22 switch sound reasonable?

I think they are not. From this PEP
<https://www.python.org/dev/peps/pep-0440/#developmental-releases>,
development releases of python are tagged with `X.Y.devN`.

Also, we can apply the *Debian test*[1]. Debian packaged python 2.7.11
<https://packages.debian.org/sid/python> into unstable, so we should
be fine. Debian also packaged pkg-config 0.29
<https://packages.debian.org/sid/pkg-config>, so it also be fine...

[1]: We know Debian is *stable* (even unstable is not unstable, real
testing goes to experimental, the worst thing happened to me was
gnome-3 stopped working), so they should have done the right thing.

I went ahead with the update in ‘core-updates’, along with a couple of
determinism patches (commits 4de3507 and 4187fe7.)
