This has come up in discussion a few times, and is now well overdue, I
think.
Python 2.7 is the last python2 version, which was sunsetted on January
1, 2020.
1) I will be making the following hopefully uncontroversial changes to
cygport in it's next release:
* Make 'inherit python2{,-disutils,-wheel}' an error
* Make 'inherit python-wheel' with PYTHON_WHEEL_VERSIONS containing "2"
or "2.*" an error.
2) Looking for packages whose names don't start with 'python', but where
the current version installs something into
/usr/lib/python2.7/site-packages/ and/or into /usr/bin/ with a shebang
containing 'python2', the following packages appear to need rebuilding
for python3:
package source package maintainer
alacarte ORPHANED (Yaakov Selkowitz)
avahi-ui-tools avahi ORPHANED (Yaakov Selkowitz)
buildbot-slave Jon Turney [1]
bzr-fastimport python-fastimport Ken Brown
bzr Jari Aalto
caribou ORPHANED (Yaakov Selkowitz)
cfget Jari Aalto
chm2pdf ORPHANED (Yaakov Selkowitz)
codeville Jari Aalto
cvs2svn ORPHANED (Yaakov Selkowitz)
d-feet ORPHANED (Yaakov Selkowitz)
getmail Jari Aalto
gnome-activity-journal ORPHANED (Yaakov Selkowitz)
guake ORPHANED (Yaakov Selkowitz)
kf5-kapidox ORPHANED (Yaakov Selkowitz)
mozo ORPHANED (Yaakov Selkowitz)
net-snmp-python net-snmp David Rothenberger [2]
offlineimap Jari Aalto
picard ORPHANED (Dr. Volker Zell)
planet ORPHANED (Yaakov Selkowitz)
rpm-python rpm Pavel Fedin
spambayes ORPHANED (Jari Aalto)
tailor Jari Aalto
terminator Mike DePaulo
urlgrabber Jari Aalto
xml2po gnome-doc-utils ORPHANED (Yaakov Selkowitz)
xxdiff ORPHANED (Yaakov Selkowitz)
[1] effectively obsoleted by buildbot-worker, so should just be removed.
[2] also needs rebuilding for perl 5.32
3) There might also still be some other packages lurking which just
install a script with a shebang containing 'python', and assume that
python is python2. I don't know how we could identify those.
4) With that done, one would hope we could just expire all packages as
with names matching:
python27
python27-* (127 of)
python2-*
python-*
But there may be some cases not caught in step 2), where
- the package is not a python module (i.e. source package is not python-*)
- the package shouldn't be removed because it's a dependency of something
So those will need to be identified and inspected to determine what
should happen to them.
5) Other post-cleanup tasks
e.g. python-beautifulsoup can become a virtual package for python-bs4,
once that name isn't being used by the python2-only beautifulsoup 3.x.
