[gentoo-dev] [PATCH 00/28] python-r1 suite EAPI 8 support/cleanup

[gentoo-dev] [PATCH 00/28] python-r1 suite EAPI 8 support/cleanup

[Michał Górny]

Hello, everyone.

Here's the big batch of patches enabling EAPI 8 support in python-r1
eclass suite.  This includes some generic fixes and cleanups.

Generally:

- all previously-deprecated stuff is now banned in EAPI 8
- some new stuff becomes deprecated and banned in EAPI 8
- some leftover Python 2 support code has been removed
- some horrid old code has been refactored

The extra deprecations/bans are:

1. `python_moduleroot` and `python_scriptroot` vars are no longer used
   (they were removed from ::gentoo in 2016).

2. `python_is_python3` is now obsolete since we don't support python2.
   Just always assume python3 ;-).

3. `python_gen*` functions no longer accept -2, -3, 'python2*'
   and 'pypy' arguments that made sense only in Python 2 world,
   in EAPI 8.  This will force some obsolete dep cleanup.

4. `PYTHON_MULTI_USEDEP` is now banned in EAPI 8, just use
   `PYTHON_USEDEP`.

5. `mydistutilsargs` has been replaced with `DISTUTILS_ARGS`.  Old EAPIs
   still allow the old variable, EAPI 8 bans it.

6. `distutils_install_for_testing --via-home` is now banned.

Please review.

Wouldn't it be cleaner to inherit eapi8-dosym.eclass in EAPIs 6 and 7
instead? Then dosym -r could be used unconditionally, and function
_python_ln_rel could be dropped altogether?

Same for python-r1.eclass (patch 20/28) and distutils-r1.eclass
(patch 27/28).

Hmm, I suppose that makes sense.  Thanks!

[gentoo-dev] [PATCH 03/28] python-utils-r1.eclass: Remove python_optimize support for py<3.5

[Michał Górny]

Remove the support code for Python 2.7, <3.5, as well as PyPy2.7.  These
are no longer supported at runtime, so byte-compiling should not be used
for these impls.

[gentoo-dev] [PATCH 04/28] python-utils-r1.eclass: Rename *into vars to use underscores

[Michał Górny]

Rename helper variables used by *into to mark them private with
underscores.  The old names are leftovers from deprecated API that
permitted setting them directly.  It was last used in ::gentoo in 2016.

[gentoo-dev] [PATCH 05/28] python-utils-r1.eclass: Eliminate local python_is_python3 uses

[Michał Górny]

Do not use python_is_python3 in eclass functions to ease banning it.
Except for wrapper setup that is still used in py2 any-r1 context,
we can unconditionally assume Python 3 everywhere.

[gentoo-dev] [PATCH 11/28] python-any-r1.eclass: Remove obsolete PYTHON_USEDEP single-r1 hack

[Michał Górny]

Remove the QA hack for PYTHON_USEDEP that originally prevented python-r1
ebuilds from wrongly depending on python-single-r1 packages.  Since
the latter no longer define python_targets*, these dependencies are now
caught without any hacks.

PYTHON_MULTI_USEDEP was a temporary transition measure, and is now
equivalent to PYTHON_USEDEP.  Ban it in EAPI 8 to clean up ebuilds.

[gentoo-dev] [PATCH 22/28] distutils-r1.eclass: Refactor --install-scripts rewriting logic

[Michał Górny]

Refactor the --install-scripts rewriting logic
in distutils-r1_python_install to be less horrid.  Instead of using
variable indirection, just inline the mydistutilsargs logic
from esetup.py and rewrite the combined argument array.

[gentoo-dev] [PATCH 23/28] distutils-r1.eclass: Replace mydistutilsargs with DISTUTILS_ARGS

[Michał Górny]

Add a new correctly-cased DISTUTILS_ARGS variable that replaces
mydistutilsargs.  Ban the latter in EAPI 8.

Retracting this one for now, as it causes failures due to 'is the same
file' copy errors with in-source builds.  Need to revisit it later
and fix the underlying issue properly.
