Bug 571266 – app-portage/gentoolkit-0.3.1: revdep-rebuild does not detect breakage that revdep-rebuild.sh does

• Product: Portage Development
• Status: UNCONFIRMED ---

[Description Denis Lisov 2016-01-08 12:36:27 UTC]

After a downgrade from Qt 5.6.0_beta (overlay) to 5.5.1:

And the system is broken indeed

[Comment 2 Kees Bergwerf 2016-01-12 15:29:48 UTC]

I had exactly the same trouble.
revdep-rebuild says everything is ok but revdep-rebuild.sh found errors.

And revdep-rebuild.sh wanted to upgrade almost the whole system, 1580 packages. So I let it go.. and almost at the end some error occurred and I deleted a pakage. Oops.. forgot about --skipfirst.

Ok with so many packages recompiled, revdep-rebuild.sh should find the rest... shouldn't it?
But it wanted to recompile all 1580 packages again.
So I looked into /var/cache/revdep-rebuild/broken_something.rr (don't know the exact name) and there are only about 25 broken files.
Then I found a tool in the package 'app-portage/pfl' called e-file:

e-file <library>.so

and it will tell which package generates that library.
After re-merging those packages, revdep-rebuild didn't find any errors.

So for the moment my problem is solved.
