Bug 277433 – --depclean doesn't handle properly shared libs with copies in multiple packages

• Product: Portage Development
• Status: CONFIRMED ---

[Description Petteri Räty (RETIRED) 2009-07-11 13:10:48 UTC]

betelgeuse@pena /usr/portage/x11-plugins/enigmail $ grep seamonkey /var/db/pkg/x11-plugins/enigmail-0.95.7-r5/*
betelgeuse@pena /usr/portage/x11-plugins/enigmail $

 * In order to avoid breakage of link level dependencies, one or more
 * packages will not be removed. This can be solved by rebuilding the
 * packages that pulled them in.
 *
 *   www-client/seamonkey-1.1.11 pulled in by:
 *     x11-plugins/enigmail-0.95.7-r5

12:38 < Betelgeuse> Can anyone explain where seamonkey comes from?
12:46 < few> does a emerge -uDN @world want to install it?
12:47 < few> do you have any other version installed?
13:01 < Betelgeuse> few: pena betelgeuse # emerge -upvDN @world | grep seamonkey
13:01 < Betelgeuse> pena betelgeuse #
13:02 < few> |grep enigmail
13:02 < chithead> possibly enigmail prefers to link against seamonkey rather than thunderbird if both are installed
13:04 < Betelgeuse> chithead: yeah indeed enigmail binaries go against seamonkey
13:04 < Betelgeuse> chithead: but it's a Portage problem
13:04 < Betelgeuse> chithead: It should figure out thbird also has the libs
13:05 < Betelgeuse> time to open a bug

--depclean should be smart enough to figure out the shared lib is also satisfied by thunderbird

The problem is even bigger with www-client/chromium.

This ebuild installs symlinks to ffmpeg's libraries in /usr/lib64/chromium-browser/. Basically, they look like this:

lrwxrwxrwx 1 root root 27 10-25 10:27 /usr/lib64/chromium-browser/libavcodec.so.52 -> /usr/lib64/libavcodec.so.52
lrwxrwxrwx 1 root root 28 10-25 10:27 /usr/lib64/chromium-browser/libavformat.so.52 -> /usr/lib64/libavformat.so.52
lrwxrwxrwx 1 root root 26 10-25 10:28 /usr/lib64/chromium-browser/libavutil.so.50 -> /usr/lib64/libavutil.so.50

Then, when calculating depclean, emerge assumes that all packages depending on ffmpeg, depend on chromium too:

 *   www-client/chromium-4.0.223.5 pulled in by:
 *     media-libs/gegl-0.1.0-r1 needs libavcodec.so.52, libavformat.so.52
 *     media-libs/xine-lib-1.1.16.3-r2 needs libavcodec.so.52, libavutil.so.50
 *     media-plugins/audacious-plugins-2.2_beta1 needs libavcodec.so.52, libavformat.so.52, libavutil.so.50
 *     media-plugins/vdr-dxr3-0.2.9 needs libavcodec.so.52
 *     media-sound/moc-2.5.0_alpha3-r3 needs libavformat.so.52
 *     media-sound/picard-0.11 needs libavcodec.so.52, libavformat.so.52
 *     media-video/ffmpeg-9999-r1 needs libavcodec.so.52, libavformat.so.52, libavutil.so.50
 *     media-video/guvcview-1.1.1 needs libavcodec.so.52
 *     media-video/motion-3.2.11.1 needs libavcodec.so.52, libavformat.so.52, libavutil.so.50
 *     media-video/mplayer-9999 needs libavcodec.so.52, libavformat.so.52, libavutil.so.50
 *     media-video/vlc-1.0.3_rc needs libavcodec.so.52, libavformat.so.52, libavutil.so.50
 *     www-plugins/moonlight-1.0.1 needs libavcodec.so.52, libavutil.so.50

Portage issue is not mozilla related.
