[gentoo-dev] [PATCH 00/18] distutils-r1.eclass D_U_PEP517=no mode & other patches

[Michał Górny]

Hi,

Here's another large-ish patchset for the Python eclass.  The primary
highlight is DISTUTILS_USE_PEP517=no mode explained below.  In addition
to that, some refactoring, bug fixes and other changes collected
to avoid updating the metadata cache twice.


D_U_PEP517=no mode basically gives you the best of distutils-r1 features
without default python_* phases or build system-specific dependencies.
This means to cover 3 use cases:

1) packages that can't use PEP517 to avoid cyclic deps in bootstrap,

2) trivial packages without a build system,

3) Python-ish packages without a PEP517 build system (e.g. using plain
   meson).

Before, these either required legacy mode (that I'd like to eventually
remove, many years from now) or using python-r1 directly.  Thanks to
the new mode, they can benefit from convenient python_* phases, default
Python deps (unless you're using DISTUTILS_OPTIONAL), the test-scope
venv logic, distutils_enable_tests, etc.

There are two main methods of using it: either declare phases up to
python_install() and install files straight to ${D}, or install them
to ${BUILD_DIR}/install during python_compile() and the eclass will pick
it up.  The latter method gives you working venv for python_test() too.

I've included a few example ebuilds in the middle of patch set.  tomli
and installer ebuilds demonstrate using python_compile() to install
Python modules and use them in tests.  gpep517 uses python_install().
gnome-abrt demonstrates working with meson (yes, I know it's the old
version).


Other changes are:

- removing incidental install of temporary cache files (*-pytest-*.pyc)
  from epytest

- internal refactoring to make post-python_install() QA checks,
  ${BUILD_DIR}/install merging and post-python_compile() test venv setup
  (in PEP517 mode) work independently of python_compile()
  and python_install() overrides

- *-nspkg.pth warning will become an error in EAPI 9

- python_domodule() now works outside src_install(), by installing
  into ${BUILD_DIR}/install (and therefore fits part with distutils-r1)

- other python_do*() and python_new*() functions now fail if called
  outside src_install()

- add `_trial_temp` to disallowed top-level packages

- minor doc fixes
