Bug 646160 – sys-apps/portage-2.3.21 - questionable list of dependency changes without revision bump

• Product: Portage Development
• Status: RESOLVED INVALID

[Description Carlo 2018-01-30 21:02:57 UTC]

Hi there. Tested the new Portage version and got - corresponding to bug 645780  - a ridiculous long list of more than 500 ebuilds to rebuild.

Here's the result checking two random ebuilds:

diff -u virtual/fortran/fortran-0.ebuild /var/db/pkg/virtual/fortran-0/fortran-0.ebuild

No difference at all.

diff -u media-libs/libaacs/libaacs-0.7.1.ebuild /var/db/pkg/media-libs/libaacs-0.7.1/libaacs-0.7.1.ebuild

No dependency change.


In its current form, this feature is not helpful.

You'll probably want to compare /var/db/pkg/media-libs/libaacs-0.7.1/RDEPEND to the RDEPEND line in $gentoo/metadata/md5-cache/media-libs/libaacs-0.7.1

vs

This doesn't make it better.

It looks like this is due to a difference in the way the atoms were evaluated. I'll look into making it normalize them prior to comparison.

If tested and it looks like portage already normalizes these properly, so the change was probably triggered by a changed eclass dependency in DEPEND such as the app-portage/elt-patches dependency added by libtool.eclass.

Seems you're right, Zac. I'm back to --dynamic-deps=y. Sorry for the noise.
