Mass rebuilds in Copr

[Iñaki Ucar]

Hi,

Is there any mechanism similar to a side-tag in Koji to rebuild a
bunch of packages without causing trouble in users' machines? Maybe a
way to "disable" or "freeze" the chroot for the users while being able
to continue building stuff?

Regards,

[James Cassell]

Fork it and rebuild there. Once you've got the order, rebuild in the original. Not sure if it's possible to merge a forked COPR, though.

V/r,

I don't think it's possible, but forking is not an option in this case (too
big). Besides, I've got the order, that's not the problem.

The issue is that there's an ABI change sitting in updates-testing for f32,
and rebuilding my Cope repo may take a week, give or take.

One option is that you can toggle off the "auto createrepo" feature.  As
long as this is off, you will build the repository in separate directory
named "devel".  When you toggle it ON back again, the repository should be
regenerated with the new packages.

Another possibility is the fork, but forking such large project would be
storage-expensive.

Actually another possibility is to build in **separate** project against
the main, large project (build time additional repo).  Then, when ready,
you could "fork back" the new project into the main existing project (we
should call this "merge" in future).  There's at least this small bug

https://bugzilla.redhat.com/show_bug.cgi?id=1851827

so honestly, this isn't well known and tested feature and I'd encourage you to
test this first on something smaller.

Thanks, this is useful!

Another question: when I toggle the auto createrepo tick back on, is
it launched automatically at that moment or do I need to push the
button?

This should happen automatically:
