Upstream compatibility with Alpine

This article explains how to do maintenance in pmaports.git, to make sure it stays compatible with Alpine edge. Upstream compatibility checks are running hourly in the monitoring repository, and the badge of upstream compatibility is visible in the pmaports gitlab project. Information might be incomplete (as of writing, this was just started to document how to fix python breakage), please extend what is missing for future reference.

To simply bump the pkgrel of a package, use.

If there is noticeable fallout for users, make a post for the edge blog.

cross / aportgen
Most of the packages in the  dir of pmaports are automatically generated from Alpine. If Alpine has a new version, and the upstream compat check complains about it, do this (example with binutils-* packages):

If you are confident that this will work, then push it directly to pmaports.git. This makes sense for gcc especially, because it needs to be updated right after gcc is updated in Alpine - or else cross compilation is broken. Other packages are usually not as urgent. If you are unsure, better make a merge request and wait until CI confirms that this builds.

Python upgrade
If python was upgraded in Alpine to a new version (e.g. 3.8 to 3.9), all packages need to be rebuilt, which:
 * Depend on libpython (e.g. ).
 * Monitoring will warn about these.
 * Install files to  (or other version).
 * Monitoring does not warn about these (would be possible with abuild#10029).
 * Use pkgs.postmarketos.org to find these.

Bump relevant pkgrels and make a MR. This should be trivial, so you can merge it once everything builds.
