Hello

I have an understanding problem with overlays and priorities, and the
Variables PORTDIR and PORTDIR_OVERLAY.

I use the musl overlay under x64. For a few days now, there have been
dev-libs/elfutils an update version 0.177, from the gentoo main repository, which portage wants to update. Previously, 0.176-r1 was installed from the musl overlay repository.

Although I use the gentoo main repository with priority -1000 (standart)
and the musl overlay has set with +50, portage wants the update
to the higher version:

Code:
[ebuild     U  ] dev-libs/elfutils-0.177::gentoo [0.176-r1::musl]


I think the problem is that here's version number versus repository priority.

Are my guesses true? And how can I set it so that the repository priority is always
has priority.

My further guess is that I have it via the variables PORTDIR
and PORTDIR_OVERLAY.
However, this approach is outdated - deprecated.

I'm a bit confused.

There is also a bug report on the topic: #701478

bye.

As you said update ignore priority (an update is more important), the priority works only if same package version being found in several overlays.

Ok. So are the rules. But this means in the interplay main repository versus overlay,
developers from the overlay repository must always have at least the same
version number, as in the main repository. Otherwise they will be overruled, despite higher
overlay priority.
Right? I think this approach is confusing for overlay developers. Also, what can I do
as a user? Setting PORTDIR and PORTDIR_OVERLAY?

That it's clear, see https://wiki.gentoo.org/wiki/Ebuild_repository#Priorities.

If you want always a package from an overlay regardless update you can mask packsge in the main repository
Code:
# echo "category/package::gentoo" >> /etc/portage/package.mask

You could e.g. try like Masking installed but unsafe ebuild repositories

You could make a postsync.d script that would search the overlay and update a mask file adding ::gentoo to them if don't want to have to keep track of added/removed package and manually updating masks (a hard-priority system for repos that also ignore updates would certainly be friendlier if it exists though, not that I know of it).

In this case the issue is that need to mask from the gentoo repos rather than a "bad" repos (basically ::musl > ::gentoo _even_ if ::gentoo has a higher version). You're gonna have a crazy amount of exceptions if you mask all of ::gentoo.
