Issue: Better fork support in cached FastPath instances #146228

jaraco · 2026-03-20T19:13:41Z

Well that's interesting. The new test is failing due to a new deprecation of forking multithreaded calls.

The issue doesn't manifest for me when I run tests locally, but that's likely because I'm running in some single threaded mode.

I see a bunch of tests using @warnings_helper.ignore_fork_in_thread_deprecation_warnings().

jaraco · 2026-03-20T20:06:07Z

Since this code has been available in importlib_metadata for a good while, I'm going to proceed with merging this so it can unblock subsequent changes (#143387).

Note: switching to 'b5e4c46be24d1fade0deda211785c04a74a722cc'.

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
