Bug 662702 – media-video/obs-studio-21.1.2: dev-lang/python-3.5.5-r1 was uninstalled despite being required a run time

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Dennis Schridde 2018-08-03 08:54:58 UTC]

After `emerge -a --depclean` I see the following:
!!! existing preserved libs:
>>> package: dev-lang/python-3.5.5-r1
 *  - /usr/lib64/libpython3.5m.so.1.0
 *      used by /usr/lib64/libobs-scripting.so (media-video/obs-studio-21.1.2)
 *      used by /usr/lib64/obs-scripting/_obspython.so (media-video/obs-studio-21.1.2)

I think media-video/obs-studio-21.1.2 incorrectly uses python-any-r1.eclass:
# @BLURB: An eclass for packages having build-time dependency on Python.

However, media-video/obs-studio-21.1.2 requires Python at run time.  It should probably use python-single-r1.eclass instead.

Thanks for the report!

Yeah, I seem to have managed to completely miss that little bit with regards to the 'python-any-r1.eclass'.  I did experiment with 'python-single-r1.eclass' as well, but that gave me some sort of issues at the time, and 'any' seemed to be a better fit (at the time).

Fill wix.

    media-video/obs-studio: switch to python-single-r1 eclass
    
    Previously, the fact that 'python-any-r1.eclass' is intended for
    build-time dependent packages only was completely missed, while
    Python is required at run-time when used for OBS Studio scripting.
