python2 removal

python2 removal

[Jon Turney]

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)

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.

I'm not interested in maintaining these any longer.  If no one else wants to 
take over, they could just be removed from the distro as far as I'm concerned. 
The only package that would suffer from this is cvs2svn, but that's currently 
unmaintained anyway.

That's fine, of course.

I meant to write some words saying 'please update or orphan (which will 
probably lead to removal)', but forgot.  Sorry about that.

NP.  I've marked them as orphaned.

Hi maintainers,

Please consider rebuilding your packages listed below for python3.

If you are no longer interested in being a maintainer for these (or all 
of your) Cygwin packages, please let us know, so we can update our 
records and stop bothering you about them!

I might look at some of the more important ORPHANED packages, as time 
permits, and some of these are candidates for removal if not updated, 
but obviously adoptions are welcomed!

Hi Jari,

In the absence of any response, I have assumed these are all orphaned.

If that's not what you wanted to happen, please let me know.

 From a brief survey, only offlineimap and urlgrabber (which should 
probably be named python-urlgrabber, since it contains a python module) 
seem to be actively maintained enough to support python3.

So I will probably remove the others, and consider if it's possible and 
worthwhile to update those.

(I also noted that breezy appears to be the python3 replacement for bzr 
and getmail6 appears to be the python3 replacement for getmail.)

I'm happy to adopt both of these. I'll give Jari a little while to
reclaim them first, not least as I'm not going to have the time to
spend on packaging these for at least a week or so, but if Jari (or
anyone else) doesn't claim them first, I'll send an ITA once I've
checked I can get the packaging to work.

Gentle ping to ask if you are still intending to package these?

Yes, they're both on my to-do list, but I've had a whole bunch of real
life come up over the past few months. If the delay is causing issues,
though, I can bump them up my priority list…

Hi Pavel,

In the absence of any response, I have assumed this is orphaned.

If that's not what you wanted to happen, please let me know.

No problem.

Hi Mike,

In the absence of any response, I have assumed this, and gtkperf, your 
only other package, are orphaned.

If that's not what you wanted to happen, please let me know.

I looked for python{,2}-foo package which have a source which isn't 
python-foo, and doesn't also produce python3*-foo (note: in many cases 
the python3 binding doesn't exist for the latest python3 version)

None of these seem to have current versions of other packages which 
depend on them, so just removing these python2 bindings would seem to be 
safe.

Many of these are old (maybe gtk2, gnome2-era) stuff which we should 
probably also work on removing.

Again, I might look at rebuilding some of the more important packages, 
as time permits, and some of these are candidates for removal if not 
updated, but obviously adoptions and input on what is no longer useful 
is welcomed!

The remaining cases of packages which have a dependency on python and/or 
python2 are either this (packages which contain a python script with a 
python shebang line), or the other case which I hadn't previously 
considered - a package which contain an executable or shared library 
linked with libpython2.7.dll.

So, again I need inspect these to determine what should happen to them.

The critical piece of data I'm missing here is which of these is true:

a) This package contains a script with a python shebang. The current 
version doesn't work when python is python3, so an upgrade is needed to 
continue working when python2 is removed, or

b) This package contains a script with a python shebang. The current 
version will continue to work when python is python3.

Jari's Debian 8/9 xlsx2csv releases have been updated to 0.20+20161027 from 
0.11+20120814.

$ sed 1q xlsx2csv.py
#!/usr/bin/env python

Does not work with python3, nor after running 2to3 fixes - see attached logs - 
IANAPythonista

Anyway pylint was not useful compared to 2to3 - see attached pylint before and 
after 2to3 logs compared to 2to3 log.

This is not an unequivocal answer to my question.

It sounds like you are saying "even the most recent version of xlsx2cvs 
doesn't work with python3", in which case the only sane option is to 
remove this package when python2 is removed.

Is that what you mean? If not, what do you mean?

Please answer with a single sentence.

Sorry if I was not sufficiently clear but that is not the case at all.

Current Cygwin package is python2 only from 2010 when python3 first came out.

You asked about the current Cygwin source package - that is all those answers 
refer to - and the logs relate to - nothing about the latest upstream package.

The Cygwin source package as distributed does not work with python3, it can not 
be easily upgraded to work with python3 using 2to3, and there is no way for us 
to rebuild it anyway, as it depends on some cygbuild "magic" not provided in the 
source package.

The latest version of the upstream package builds, installs, checks, and runs 
fine using minimal cygport and python3 cygclasses, as referred to in the 
scallywag links provided.

I am replacing the upstream man page provided, as it was written in POD, applies 
to the outdated 2010 release, and the latest upstream version's help has many 
more options, is more comprehensive, and was started with help2man.

I updated the the latest from upstream repository and it shoudl now
work with Python 3.

So here's the list, with *tentative* notes of the disposition for each 
package.

As before, I might look at rebuilding some of the more important 
packages, as time permits, and some of these are candidates for removal 
if not updated, but obviously adoptions and input on what is no longer 
useful is welcomed!

I've also adjusted numerous old package versions which depend on 
'python' to depend on 'python2' when that's what they actually require, 
so they will become not-installable when python2 is removed, and can 
subsequently be expired.

(often these are historical package requirements which were synthesized 
from the current package requirements from before we had per-version 
requirements)

Contrariwise, a few packages (e.g. clang, ibus, libglib2.0-devel, llvm, 
lv2-devel, mysql-server, pulseaudio-equalizer) which depend on python2, 
but contain a script which appears to work with python3 have been 
adjusted to depend on 'python'

Hi Jari,

I believe these packages all need updating for python3.

Please confirm if this assessment is correct, and let me know if you 
intend to do this, otherwise I will assume these packages are orphaned 
and they will be removed.

Thanks.

In the absence of any response, I have assumed they are orphaned, and 
removed these.

If that's not what you wanted to happen, please let me know.

Hi Marco,

Currently, octave-miscellaneous depends on python2.  It would help me 
greatly if you could tell me if that's correct or if it should depend on 
python (if all the scripts in it also work with python3), or it should 
be updated to work with python3?

Additionally, I noted that subversion-tools depends on python (due to an 
explicit requires in the cygport), but... I don't see any python scripts 
there, so I wonder if that should just be removed in future.

So, I think I've more or less come to the end of packages which seems 
worthwhile for me to rebuild and/or update.

(There's several things which I haven't updated because their 
dependencies also need updating - usually glib, which definitely needs 
attending to, but I'm not going to pull on that thread right now...)


I think the next step is to remove the python27 package itself.

This will make it impossible to install anything which requires it on 
new installations (existing installations which already have the package 
installed will be uneffected).

Once the wailing, rending of garments and gnashing of teeth has died 
down, I can remove the python2 modules and bindings at leisure.

Marco,

As python maintainer, any thoughts on when to do this? Anything you want 
to get done before that?

I'll have to look these over in more detail, but most of the python-*- 
{common,devel,wheel) seem reasonable to allow to continue to exist.

python2-xapian-doc can obviously also be removed.

python-wx-devel is the last remnant of python2 bindings for wx (the 
python3 binding comes from a different, irregularly named source package 
python3-wx), so can also be removed.

python-{gdal,netsnmp} are irregularly named, and should be obsoleted and 
renamed as python3-foo and/or python3X-foo when they next get rebuilt.

There's still some packages which depend on python2 and python2 modules 
remaining, which haven't been rebuilt yet, which are probably all 
candidates for removal if not adopted.  I'll produce a list before that 
happens, though.

On to python3.5 (EOL Sep 2020) next, I suppose...

Cc:ing Hamish as a note that if/when python3-wx is updated, we should 
see if it's now possible to rename the source package to python-wx.

Unrelated question: Do you mind if I vault the (orphaned, last updated 
circa 2016) wxWidgets 2.8 packages, which I assume are of very limited 
use to anybody...

Okay, I'd be happy to try renaming the package to python-wx the next 
time I update python3-wx.

I'm indifferent to the wxWidgets 2.8 packages, I've never used them and 
wxWIdgets 3.0 is also pretty compatible with 2.8 from my understanding, 
so the 2.8 packages aren't needed.

I realise I forgot to ask, but how could I go about renaming python3-wx 
to python-wx when I update? I also maintained python-wx, so I shouldn't 
need any extra permissions I don't think.

Best,

Uh, yeah, this is made more complex as we had a 'python-wx' source 
package (for the python2 bindings, now removed), and a separate 
'python3-wx' source package (for python3 bindings).

I guess what wants to happen is:

* (If you care about such things) Merge the python3-wx history into the 
python-wx packaging git repo (git merge --allow-unrelated-histories 
seems like it might be the right voodoo runes).

* Rename python3-wx.cygport to python-wx.cygport and update version or 
bump release.
  * When it comes to uploading the rebuilt packages, there's 
unfortunately (currently) a manual step involved (for me to) adjust the 
"allegiance" of the 'python3n-wx' install packages from the 'python3-wx' 
source package to 'python-wx', but I'll do that when needed (or maybe 
even get around to automating it this time...)

Here's an updated list of the remaining packages, after removals, 
rebuilds and/or updates:
