[gentoo-user] Python 3.11 USE flags being flipped on

[gentoo-user] Python 3.11 USE flags being flipped on

[stefan11111]

I just tried to run today's emerge, when I saw that python 3.11 was 
being pulled in and packages had this USE flag flipped on.
I tried masking the USE flags for python 3.11 and that had the effect of 
creating the same problem, but with python 3.10 instead.
After masking python 3.10 too, I get this:

$ emergeallk @world

These are the packages that would be merged, in order:

Calculating dependencies... done!
Dependency resolution took 3.38 s (backtrack: 0/20).


!!! Multiple package instances within a single package slot have been 
pulled
!!! into the dependency graph, resulting in a slot conflict:

dev-lang/python-exec:2

   (dev-lang/python-exec-2.4.10:2/2::gentoo, ebuild scheduled for merge) 
USE="(native-symlinks) -test" PYTHON_TARGETS="(pypy3) (python3_12) 
(-python3_10) (-python3_11)" pulled in by
     (no parents that aren't satisfied by other packages in this slot)

   (dev-lang/python-exec-2.4.10:2/2::gentoo, installed) 
USE="(native-symlinks) -test" PYTHON_TARGETS="(pypy3) (python3_10) 
(python3_11) (python3_12)" pulled in by
     dev-lang/python-exec[python_targets_python3_11(-)] required by 
(dev-lang/python-3.11.6:3.11/3.11::libressl, installed) USE="ensurepip 
gdbm lto ncurses pgo sqlite ssl verify-sig -bluetooth -build -debug 
-examples -libedit -readline -test -tk -valgrind"





It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.


emerge: there are no ebuilds to satisfy

Any ideas?

Python 3.11 is the default right now (and has been for some months now.) 
You should follow the python upgrade procedure (there should be a news 
item for this, you can view those with "eselect news list".)

After the upgrade, it might be easier to block new python versions until 
Gentoo switches the default version again later. This has been a 
mainstay in my packacke.mask for ages now:

   # Prevent a shitload of different python versions from being installed
   <=dev-lang/python-3.10
   >=dev-lang/python-3.12

(Obviously the versions are gonna differ over time.)

I don't set PYTHON_TARGETS nor PYTHON_SINGLE_TARGET. Currently, the 
defaults are:

   PYTHON_SINGLE_TARGET="python3_11"
   PYTHON_TARGETS="python3_11"

When the default Python version changes, this is usually announced 
through a portage news item and you'll get a notification about it when 
you sync.

If you really want to stick to 3.10, you can try setting the above vars 
for portage. You can do this in your package.use:

   */* PYTHON_TARGETS: -* python3_10
   */* PYTHON_SINGLE_TARGET: -* python3_10

However, 3.11 is the current default for a reason. Maybe some packages 
really require it, and thus you will end up with both 3.10 and 3.11 
installed. If you just want a single version installed, then it's a good 
idea to not go against the current portage default.

I have done the migration to python 3.12.
The problem is that portage is pulling in python 3.11.

I have PYTHON_TARGETS="python3_12" in make.conf.
And:
app-eselect/eselect-repository python_single_target_python3_12
media-video/mpv python_single_target_python3_12
dev-util/glib-utils python_single_target_python3_12

In package.use

Putting PYTHON_SINGLE_TARGET="python3_12" in make.conf changes nothing.

The problem is that I'm on python 3.12 and portage is pulling in an 
older version.

Should have mentioned it in the first post, then it would be easy to
look into it and tell you that media-libs/mesa is only supported up to
3.11 (in the ebuild anyway). You can try adding 3.12 to the ebuild
yourself, as it seems to be working fine according to
https://bugs.gentoo.org/919912

Thanks.
But why did this happen now, and not when I migrated to python 3.12?

A python version jump in gentoo is always a horrible work:
Many ebuilds have not been updated and pull in unnecessarily
python 3.11. If you use any of these packages, you need a patched
version of them in your overlay.

The list is not complete, even less if you have USE=python in
some packages.

The most notable package is www-client/firefox which is the only
one which actually *needs* <python-3.12 - the others just have
a broken dependency declaration.

Finally got to adding patched ebuilds to my overlay.
Everything works so far.
This got me wondering though, is there no way to fix this globally
via make.conf instead of adding patched ebuilds to my overlay?

No. Until https://bugs.gentoo.org/209653 is fixed (which did not
happen since 16 years and presumably never will), there is no
other way to fix dependencies than to copy the ebuild to some
overlay.

The fix to stefan11111's problem is surely to extend the allowed
python versions in PYTHON_COMPAT though, the solution for that would
be different than changing the dependencies directly.

For the case that this was not clear: This is what I meant.
You would have a hard time to fix the dependencies in your
overlay "directly" in any other way than by editing the value
of PYTHON_COMPAT in the ebuild in your overlay.

However, this is only about *how* you modify the ebuild; my
point was that with current portage you *cannot avoid* to
modify the ebuild.

Interesting read.
Would be nice is there was a way to set PYTHON_COMPAT through 
envvars/make.conf vars like MYMESONARGS.
This seems like such an easy fix too. Just set PYTHON_COMPAT to include 
python 3.12 and be done with it.
Another thing would be if adding dev-lang/python-3.11.7 to 
package.provided only made portage pretend that
dev-lang/python-3.11.7 is installed, and not every version of python3.
Or if we had an easy way to patch ebuilds like we have 
/etc/portage/patches...
I can't even make a dummy ebuild for python 3.11, since those ebuilds 
won't use python 3.12 even
if it is installed if it isn't part of PYTHON_COMPAT(which is a 
reasonable choice).

Anyway, at least I don't have many ebuilds to patch to support python 
3.12.

If you're comfortable with git, you could switch your ::gentoo repo to
a git checkout and edit/commit your changes there. Then when you git
pull/rebase, you'll find out about any merge conflicts.

This is not possible, the reason being implicitly explained
in the above bug:
PYTHON_COMPAT is used to calculate the dependencies from the
ebuild which are package metadata.

And this metadata must have been already calculated when
portage is started: if the ebuild would have to be interpreted
whenever the metadata is needed, portage would be unbearable
slow. Bot to speak about difficulties with things like tbz2
files which in general only contain the metadata and not
necessarily the ebuild anymore.

This is the reason why the emerge --regen and emerge -u ...
phases are practically disjoint (and why emerge --metadata
takes ages, in general, unless you use a repository with
already generated metadata).

What you can do is the modify the corresponding eclass(es)
to auto-add python 3.12 to PYTHON_COMPAT.
After that change to take effect on the metadata, you have
to call emerge --regen for the main gentoo repository.
Note however, that - roughly speaking - this way you have
made your own "overlay" of the gentoo repository, and you
have to think of a way how to sync/merge your modification
with the gentoo repository regularly. At the very least,
you have to call the processor- and time-consuming
emerge --regen after every syncing.

Keeping some dozens packages in a "regular" overlay is
much simpler than practically maintaining all packages
in a local overlay...

For portage, this trick would almost work, but portage would
resolve dependencies falsely and e.g. not recompile
packages which should be recompiled to work with
python:3.12.
Also, USE-dependencies with python versions
(e.g. python_targets_python3_11) could not be
resolved as you cannot package.provide USE-flags.

Moreover, even if the dependency problem could be solved,
the ebuilds would fail nevertheless if e.g. python-3.12 is
not in PYTHON_COPMPAT when it should be for several reasons:

1. The eclass would check whether the python:3.11 version is
present and use that for compilation.
2. The result would be put into the directory for the
python:3.11 version where python-3.12 does not find it.

/etc/portage/patches can patch practically everything
in ebuilds *except metadata*. That's exactly what
bug 209653 is about.

I see.
Should I at least file bugs about those packages?
Surely there is no reason to artificially limit the python version in 
::gentoo?

Yes, especially if the package has a test suite that passes under
python-3.12. Most python packages are community-maintained and it
feels a lot safer bumping a package you aren't familiar with if it has
a passing test suite. But even an "it works" report is helpful.

Ran the tests and filed a bug here:
https://bugs.gentoo.org/920933
Has the bug filing form changed?
I don't remember seeing that template when filing bugs.

I skipped dev-libs/glib because it requires dbus and fails with a linker 
error when building it.

I tried adding -Wl,--unresolved-symbols=ignore-all and
-Wl,--warn-unresolved-symbols to my LDFLAGS,
both of which somehow made the compilation fail earlier.

Without those options, the compilation would fail with a linker error.
With those options the compilation failed much earlier with a compiler 
error.
Can anyone explain why that happened?
