Check for available Python 3.14 and Python 3.15 installations in the configure script. This allows us to use the 3.14 version installed by actions/setup-python in our 3.13 CI, rather than falling back to a 3.12 copy baked into the image.

I've omitted the blurb entry for this one, because while this is technically a change to the build, these regeneration scripts usually aren't visible in practice. If anyone is strongly in favor of adding a news entry here, feel free to let me know.

For anyone interested, the precedent here is that we check for an installed 3.15 copy in 3.14's configure script:

cpython/configure.ac

Line 208 in d14697d

[python$PACKAGE_VERSION python3.15 python3.14 python3.13 python3.12 python3.11 python3.10 python3 python],

However, we don't do this for any other branches, at least as far as I can tell.

Noting this is similar to #137619 that only backported to 3.14.

We could mark this as a backport of that, and include the NEWS. Or try a backport of that. But I don't mind much either way :)

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot AMD64 Arch Linux TraceRefs 3.13 (no tier) has failed when building commit dc12380.

What do you need to do:

  1. Don't panic.
  2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/#/builders/1472/builds/897) and take a look at the build logs.
  4. Check if the failure is related to this commit (dc12380) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:

https://buildbot.python.org/#/builders/1472/builds/897

Failed tests:

  • test_urllib2net

Note: switching to 'dc12380f600d82343edd6d6bfb2375568db96f26'.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

HEAD is now at dc12380f600 [3.13] gh-142457: Support using 3.14 and 3.15 for generation scripts (GH-142499)
Switched to and reset branch '3.13'
