[gentoo-portage-dev] distfiles in overlays?

[Joakim Tjernlund]

Sometimes I have to move files from my layman overlays distfiles to /usr/portage/distfiles
in orders to rebuild older stuff not in gentoo anymore.

Should not emerge search in distfiles where the ebuild resides?

What about eclass? What is the search order here?
If I got a customized user.eclass in my overlay, can I have this eclass take
precedence over the one in /usr/portage/eclass ?

distfiles are not part of repository. The /usr/portage/distfiles path
is just wrong and you shouldn't be using it.

It follows masters. First the repository with ebuild. If it's not
there, it looks through all masters, then their masters etc.

Yes. 'man 5 portage', look for eclass-overrides. Note that this will
effectively discard metadata cache and therefore make stuff slow after
syncing	.

I am not "using" it, emerge does so by default. It would be nice if portage tried
distfiles in the overlay it found the ebuild in or if one could configure which distfiles
to use in repos.conf. Makes it much easier to keep track of different source files
and then storing then in a git repo so one can find them after they are gone from gentoo.

Wouldn't it be better to fix the ebuilds in the overlay to point at a current 
URL for the tarball?

> Should not emerge search in distfiles where the ebuild resides?

No, the ebuild should specify where to get the tarball.

Not sure these comments are what you're looking for but it sounds like you 
just need to fix the ebuilds in your overlay to point at the distfiles in your 
overlay as a SRC_URI.

Just my 2¢, disregard if too assumptive.

It is entirely possible for an ebuild to install a pkg from sources
only from the pkg's files directory.  Provided the sources are within
the size limits for the files directory.  Although an overlay may be
allowed to go past that for a non-gentoo tree pkg & ebuild.
