Description Michał Górny archtester Gentoo Infrastructure gentoo-dev Security 2010-04-03 11:40:03 UTC
Would it be possible to implement full symbol table checking in revdep-rebuild in addition to plain 'NEEDED' check?

A particular case where this would be very useful is after glib downgrade. The new version (from gnome overlay) introduces few new memory allocation functions without SONAME bump, which applications compiled with new glib in place tend to use (due to macros?).

After downgrading to older version of glib, neither preserved-libs nor revdep-rebuild considers any of the applications or libraries broken, though they fail to run due to missing symbols. If revdep-rebuild was able to check for such symbols, it would become even more useful than before.

So far everything that has been tried has resulted in a lot of false positives.
