Hello.

As you might already know, we have recently merged in the Python 
3.10side tagto Rawhide, despite several builds not succeeding.We always 
aim for some compromise between having the side tag open for too long 
and having too many failures.

https://fedoraproject.org/wiki/Changes/Python3.10

The packages, when not rebuilt, are not installable in rawhide, hence 
fixing them should be our top priority. If you need help with 
Python-related issues, we (the Python Maintenance team at Red Hat) are 
happy to help. Unfortunately, several packages fail to build for 
Python-unrelated reasons.

Most of the packages only fail to build because their dependencies were 
not yet rebuilt. Chances are, you already got an automated 
F35FailsToInstall bugzilla from Miro, that your package fails to 
install. It would be really helpful if you could find the missing 
dependency and mark the bugzilla for your package dependingon the 
bugzilla for the missing dep. Weslowly progress to do that as well, but 
your help is crucial here.

If your package fails because there isanon-dependency problem, you might 
have already received a bugzilla from us in the past. If the build 
failure is related to changes in Python 3.10, it should contain some 
hints about the problem.

# What to do?

General advice: If you are aware of the problem and working towards 
fixing it, set your bugzilla to ASSIGNED to avoid further automated 
reminders.

If blocked by dependencies, do not close the bugzillas as NOTABUG or 
DUPLICATE just because it is "not a problem in your package". The 
automation will file new ones anyway.

## My package fails to build because it has test failures in %check

Please, try to resolve the failures. If you are confident that the 
package works fine, but the tests are wrong, skip some failing tests, 
ideally with a link to an upstream issue. Do not disable (e.g. comment 
out) all tests just to unblock the rebuild of your package, it usually 
only hides the problem.

## My package fails to build because it has broken build dependencies

Please try to track the missing build dependencies in Bugzilla. If 
possible, help the maintainers of your dependencies to get them rebuilt. 
When in need of escalation, ask us for provenpackager help (ideally with 
pull requests to be merged). Once possible, rebuild your package (no 
need to bump the release, we already did that). When you do, the 
bugzilla will eventually get automatically closed, but you can do that 
manually as well.

## My package was rebuilt with Python 3.10 but it has broken runtime 
dependencies

Please try to track the missing runtime dependencies in Bugzilla. If 
possible, help the maintainers of your dependencies to get them rebuilt. 
When in need of escalation, ask us for provenpackager help (ideally with 
pull requests to be merged). When the dependencies are rebuilt, your 
package will install successfully once again and the bugzilla will 
eventually get automatically closed, but you can do that manually as well.

## My package failed to build but installs just fine

Some packages that only require libpython3.9.so.1.0 will successfully 
pull in the python3.9 package as a dependency and hence they don't have 
installation issues. They need to be rebuilt with Python 3.10 anyway, we 
don't want Fedora users to pull in two Python versions unless they need 
them for development purposes.

## How to run things locally?

You can use mock. Make sure to:

  1. Clear all caches first: $ mock -r fedora-rawhide-x86_64--scrub=all
  2. Use the Koji repo: $ mock -r fedora-rawhide-x86_64 
--enablerepo=local ...
