Subject: qtwebengine-opensource-src: Python2 removal in sid/bullseye

Date: Fri, 30 Aug 2019 07:49:37 +0000

Package: src:qtwebengine-opensource-src
Version: 5.11.3+dfsg-2
Severity: normal
Tags: sid bullseye
User: debian-python@lists.debian.org
Usertags: py2removal

Python2 becomes end-of-live upstream, and Debian aims to remove
Python2 from the distribution, as discussed in
https://lists.debian.org/debian-python/2019/07/msg00080.html

Your package either build-depends, depends on Python2, or uses Python2
in the autopkg tests.  Please stop using Python2, and fix this issue
by one of the following actions.

- Convert your Package to Python3. This is the preferred option.  In
  case you are providing a Python module foo, please consider dropping
  the python-foo package, and only build a python3-foo package.  Please
  don't drop Python2 modules, which still have reverse dependencies,
  just document them.
  
  This is the preferred option.

- If the package is dead upstream, cannot be converted or maintained
  in Debian, it should be removed from the distribution.  If the
  package still has reverse dependencies, raise the severity to
  "serious" and document the reverse dependencies with the BTS affects
  command.  If the package has no reverse dependencies, confirm that
  the package can be removed, reassign this issue to ftp.debian.org,
  make sure that the bug priority is set to normal and retitle the
  issue to "RM: PKG -- removal triggered by the Python2 removal".

- If the package has still many users (popcon >= 300), or is needed to
  build another package which cannot be removed, document that by
  adding the "py2keep" user tag (not replacing the py2remove tag),
  using the debian-python@lists.debian.org user.  Also any
  dependencies on an unversioned python package (python, python-dev)
  must not be used, same with the python shebang.  These have to be
  replaced by python2/python2.7 dependencies and shebang.

  This is the least preferred option.

If the conversion or removal needs action on another package first,
please document the blocking by using the BTS affects command, like

  affects <bug number of blocking py2removal bug> + src:qtwebengine-opensource-src

If there is no py2removal bug for that reverse-dependency, please file
a bug on this package (similar to this bug report).

If there are questions, please refer to the wiki page for the removal:
https://wiki.debian.org/Python/2Removal, or ask for help on IRC
#debian-python, or the debian-python@lists.debian.org mailing list.

Small correction: s/qtwebkit/qtwebengine/.

QtWebEngine bundles Chromium whose upstream is actively working on
Python 3 port [1]. Most probably it won't be ready in time for Bullseye,
but for Bookworm it should be ready (or rather, Qt WebEngine 6 will
use Python 3, and we will remove Qt WebEngine 5).

There are also patches from the FreeBSD maintainer [2], but they are huge
(2200 lines in total) and the author reports that they cause some JS errors,
so I would better not apply them and wait for an official port.

Qt WebEngine in Debian is not supported from security point of view anyway,
so I think it should be fine to let it use Python 2 in Bullseye.

Except that qt6-webengine still uses python2. Hence cloning this bug to
also track the issue in qt6-webengine.

When qtwebengine-opensource-src is removed a lot of packages will have a problem because they are not ready for qt6.
Is it a bookworm release goal to remove the python2 interpreter also for packages that just build-depend on it?
If so, the FreeBSD patch (or a backport from the qt6 package) might be worth a look.

This is now literally the last package that has build depends on python2 in bookworm.
Is there a chance to move the experimental package to sid soon?

Done!

It requires binNMU of two reverse deps, that is tracked in #1025055.
