Technically, p-any-r1 can depend on single-impl packages, and such dependencies now require explicit PYTHON_SINGLE_USEDEP. Since this isn't strictly necessary at the moment, and I see no reason to implement this early, let's keep the bug open in case anyone ends up needing it.
@Nick, do you have a use case for this?
I have an ebuild which used python-any-r1 to depend on fontforge[python] at build time. Fontforge ebuild uses python-single-r1. I just noticed (yesterday) that this is no longer installable, probably has been the case for some time due to python-single-r1 changes. I'm not entirely sure what changed exactly but it sounds to me like this feature is now necessary?
Ok, thanks for the info. Now that it could actually be used, I'm going to look into implementing it in the next few days.
I've just sent patches to gentoo-dev. I'd appreciate if you could test whether they work for you.
Also here, if GH is more convenient for you: https://github.com/gentoo/gentoo/compare/master...mgorny:python-any-usedeps
The eclasses pulled from the tip of your python-any-usedeps branch (with all four patches applied) seem to be working at a first glance. For the record, I changed in my ebuild: # Old (boring) way (EAPI 6) -- no longer working DEPEND="$(python_gen_any_dep \ 'media-gfx/fontforge[python,${PYTHON_USEDEP}]')" python_check_deps () { has_version "media-gfx/fontforge[${PYTHON_USEDEP}]" } to # New (exciting) way (EAPI 7) BDEPEND="$(python_gen_any_dep \ 'media-gfx/fontforge[python,${PYTHON_SINGLE_USEDEP}]')" python_check_deps () { has_version -b "media-gfx/fontforge[${PYTHON_SINGLE_USEDEP}]" } And manually inspected the resulting dependency string with new eclass, which seems to be sensible: || ( ( dev-lang/python:3.8 media-gfx/fontforge[python,python_single_target_python3_8(-)] ) [ ... and so on ... ] ) And confirmed the package actually satisfies dependencies and compiles using the correct python version. Didn't test anything else. Thanks!
