Created attachment 209389 [details, diff] fix backtracking display (from bug #291142) If this patch is saved as /tmp/backtrack_display.patch, then it can be applied as follows: patch /usr/lib/portage/pym/_emerge/depgraph.py Please apply this patch, try the same update command again, and post the output. If the output is no different, then please post --debug output.
(In reply to comment #1) > patch /usr/lib/portage/pym/_emerge/depgraph.py I mean: patch /usr/lib/portage/pym/_emerge/depgraph.py /tmp/backtrack_display.patch
This should be fixed in 2.1.7.4 and 2.2_rc49 (if it's the same as bug 291142). Please reopen if not.

do you want i try your patch with 2.1.7.4 ?

It's supposed to be a hint that you need to unmask a newer version of ffmpeg in order for the x264 and mplayer updates to proceed. It's normal to only see this message when you use --deep or --complete-graph, since otherwise, not all dependencies are accounted for.
Thanks for explanation! After an update of mplayer and libx256, with --deep i have the same answer.

[Yes/No] ^C i understanrd your explanation but why with --deep, emerge don't check that update of x264 broke a dependencency?
(In reply to comment #7) > i understanrd your explanation but why with --deep, emerge don't check that > update of x264 broke a dependencency? It's a performance optimization. It would be a waste of time to have it enabled for every little dependency calculation, so if you want to account for all dependencies, you have to use --deep or --complete-graph. The --deep option alone is often close enough, but not always. When --deep is used together with world, it is equivalent to --complete-graph.
ok it's perfectly clear for me. Thanks you! *** This bug has been marked as a duplicate of bug 291142 ***
