Hi, emerging kde-base/kde-meta-4.11.2 seems to run update-mime-database /usr/share/mime for each of its dependencies which is here more than 200 times. This is taking most of the wall-clock time when emerging a new version of kde. Is this really necessary? Thanks for looking into it, Helmut (I'm running the GIT version of portage) emerge --info kde-base/kde-meta Portage 2.2.7_p5 (default/linux/amd64/13.0/desktop, gcc-4.8.1, glibc-2.17, 3.11.4-gentoo

Same happen here. Such thing let update extremely slow. Is this really necessary? Regards ---

Every KDE package unconditionally runs that to ensure update-mime-database via fdo-mime eclass, to ensure the MIME database is up-to-date. In order to do this on a per-package basis, we would need to inspect over 500 packages. (In reply to Zhu Sha Zang from comment #1) > Same happen here. Such thing let update extremely slow.

The issue of the slow mime database update in =x11-misc/shared-mime-info-1.2 can be fixed by re-emerging the package bug #487504. Maybe package maintainer will do a revbump to force the rebuild.
