[gentoo-soc] Fwd: Multiple Repository Support in Portage - Week 1 and 2

[Otávio Pontes]

Hi,

I am writting my progress report for weeks 1 and 2.
My version of Portage is already loading repositories from repos.conf
and it’s still loading overlays from PORTDIR_OVERLAY. PORTDIR is still
the main repository, but it’s not necessary to set it in make.conf.
You can set that in repos.conf. I would like to change that, so we
will no longer need a main repository, but i think it will be too much
work, because PORTDIR variable is used all over portage code. PORTDIR
and PORTDIR_OVERLAY variables are updated with information loaded from
repos.conf, so it was easy to fix portage and other tools should work
without any changes.

It's possible to set priorities for all repositories, even PORTDIR and
overlays, in repos.conf. The _local_repo_config class was replaced by
RepoConfigLoader and the code that used it in portdbapi is now using
directly this class. Treemap and _repository_map dicts in Portdbapi
are also no longer necessary because they are already defined in
RepoConfigLoader. So they are no longer created in portdbapi.

My code is available in
git://git.overlays.gentoo.org/proj/portage-multirepo.git or in
overlays.gentoo gitweb.
