Hi,

Here's the largest batch of eclass updates in quite some time. They
combine some new features needed for PEP 517 packages, other new
features, refactoring, cleanup and cosmetic changes -- hopefully
to stop the cache updates for some time.

The changes can be also reviewed on GitHub, particularly if you want
to see the big diff rather than the 30 individual changes: https://github.com/gentoo/gentoo/pull/24065

The highlights are:

1. A new distutils_pep517_install function is introduced that carries
the "core" PEP 517 functionality (previously inline
in distutils-r1_python_compile). This is mostly an internal change,
except that it can be used to install additional packages required
for tests (right now isort & pip need it). New isort revision
is included.

2. Some deprecated stuff that is no longer used in ::gentoo is removed.
Since it causes failures in global scope, there's little risk
of accidentally reintroducing its use.

3. python-any-r1 + python-r1 any-of API is now much more verbose.
It is explaining why a particular implementations is selected
or rejected. In additional to that, a new python_has_version()
wrapper is introduced that serves as a verbose alternative
to has_version() for use in python_check_deps(). This particularly
applies to USE=doc via distutils_enable_sphinx. (requested by soap)

4. build_sphinx regression when Sphinx is not available for the current
Python version is fixed. It was broken by PEP 517 changes.

5. More complex inline Python invocations now use heredoc syntax
instead of `-c` (thanks to arthurzam for the suggestion!). This
improves readability a lot.

6. python_optimize is also more verbose now.

7. python_gen* now accept stdlib versions in additional to exact
interpreter names. The primary use is replacing backport deps like:

$(python_gen_cond_dep ... python3_7 pypy3)

with more maintanable:

$(python_gen_cond_dep ... 3.7)

The big difference is that the latter doesn't need to be updated
every time PyPy3 switches to a newer stdlib version.

8. The eclasses now issue a QA warning if the ebuild has been updated
recently (i.e. in 2022, through looking up the Copyright line)
and PYTHON_COMPAT still lists old implementations. (requested
by sam).

9. Minimum tomli dep is raised to aid people who don't update their
systems often enough.

Avoid checking the implementation from EPYTHON via fallback iteration.
While there's no technical harm in doing that, now that we output
verbosely the users will notice ;-).

Move the EPYTHON validity check from _python_EPYTHON_supported()
to python_setup() where it belongs. This avoids unnecessarily retesting implementations taken from PYTHON_COMPAT and paves the way towards
moving the common logic to python-utils-r1.

Generate simpler USE-deps inline in python_gen_cond_dep() and remove _python_gen_usedep(). The original code always repeated USE deps
on all targets to aid Portage in giving better suggestions. However,
since there always will be exactly one implementation selected, this
is unnecessary and we can just have every cond-dep match exactly that
one target.

Update _python_impl_matches() (used to implement python_gen*,
python_setup) to support specifying stdlib versions ("3.8", "3.9")
in addition to exact implementation names. This makes handling PyPy3
version changes much easier when dealing with backports.

For example, if you specify "3.8", then the spec will match python3_8
and pypy3, for as long as we supply PyPy3.8. Once we upgrade to PyPy3.9 completely, it will stop matching pypy3 and we won't have to manually
keep updating these deps.

Fix the regression in calling sphinx-build for the non-autodoc case
that causes the build to fail if dev-python/sphinx isn't built
for the newest Python interpreter available. To account for this,
we need to call sphinx-build as an executable (i.e. via python-exec).

Ideally, build_sphinx would be aware of which case it is used for,
and use appropriate invocation. Unfortunately, we cannot do that
without breaking backwards compatibility. However, we can simply check
if Sphinx is available via ${EPYTHON}, and fall back to calling
python-exec directly. This is effectively equivalent to choosing
the specific invocation directly, as python-exec would have respected
the implementation specified by EPYTHON anyway if sphinx-build
executable was available for it.

Fixes: f6a17acb8b7c (...: Run sphinx-build via EPYTHON)

I like this, but just a question -- is this patch just an example of
how we can transition other ebuilds, or are you planning a
larger-scale replacement?

Also, I've always felt a little uncomfortable with the
python_check_deps() functions because of how easy it is to mess them
up. E.g., app-emulation/spice/spice-0.15.0.ebuild contains:

python_check_deps() {
has_version -b ">=dev-python/pyparsing-1.5.6-r2[${PYTHON_USEDEP}]"
has_version -b "dev-python/six[${PYTHON_USEDEP}]"
}

It should have a &&, right? There are many more instances of this in ::gentoo.

I wonder if this wouldn't be a good opportunity to change the API a
little. Could we make python_has_version take multiple arguments and
return true iff all are satisfied? Maybe like this?

python_check_deps() {
has_version \
-b ">=dev-python/pyparsing-1.5.6-r2[${PYTHON_USEDEP}]" \
-b "dev-python/six[${PYTHON_USEDEP}]"
}

What do you think?

Hm, maybe it's less common than I thought. The only other instance I
could find in a quick scan was dev-python/dbus-python/dbus-python-1.2.18.ebuild.

I like this, but just a question -- is this patch just an example of
how we can transition other ebuilds, or are you planning a
larger-scale replacement?

I'm not planning to do this proactively, at least at this time. Though
maybe it would be a good idea.

Also, I've always felt a little uncomfortable with the
python_check_deps() functions because of how easy it is to mess them
up. E.g., app-emulation/spice/spice-0.15.0.ebuild contains:

python_check_deps() {
has_version -b ">=dev-python/pyparsing-1.5.6-r2[${PYTHON_USEDEP}]"
has_version -b "dev-python/six[${PYTHON_USEDEP}]"
}

It should have a &&, right? There are many more instances of this in ::gentoo.

Yes. Though I think the "more common" mistake is not using "-b" while
it's the correct option most of the time.

I wonder if this wouldn't be a good opportunity to change the API a
little. Could we make python_has_version take multiple arguments and
return true iff all are satisfied? Maybe like this?

python_check_deps() {
has_version \
-b ">=dev-python/pyparsing-1.5.6-r2[${PYTHON_USEDEP}]" \
-b "dev-python/six[${PYTHON_USEDEP}]"
}

What do you think?

I suppose it could make sense, as well as defaulting to "-b". However,
I need to think about it. Maybe I'll defer the addition of
python_has_version to get the API cleared out and merge the rest
~tomorrow.

Hi,

Here's the largest batch of eclass updates in quite some time. They
combine some new features needed for PEP 517 packages, other new
features, refactoring, cleanup and cosmetic changes -- hopefully
to stop the cache updates for some time.

The changes can be also reviewed on GitHub, particularly if you want
to see the big diff rather than the 30 individual changes: https://github.com/gentoo/gentoo/pull/24065

lgtm, with the caveat of leaving out the has_version bits as per
matt's comments for now, so we can flesh it out.

While we're meddling with the eclassses, could we consider fixing
the 'locale' calls on musl? musl guarantees a UTF 8 locale (I _think_
C.UTF-8) but the current eclass logic leads to log spam as the command
doesn't exist on musl systems.

best,
sam

Someone might want to look at packaging this utility then: https://gitlab.com/rilian-la-te/musl-locales

I briefly toyed with it while trying to understand the
lxml/ISO-8859-15/repoman bug (still need to go upstream; on TODO list), and
it does execute on musl once compiled and lists the locale as C.UTF-8. But
I couldn't find any actual locale files to see if it can reliably switch between them. I read somewhere that one could borrow the locale files from glibc, but no set instructions on how to actually go about doing that.

That said, its existence in a musl stage would solve the problem highlighted
by tools blindly trying to call 'locale' and logging that it doesn't exist.

Well, this seems like a rather trivial fix, so I've just added it on top
of the existing batch.
