Some feedback from a review session using Claude Opus. There are some edge cases that would be good to fix:

  • The claim on the async generator should only have one owner. proposed fix. This adds a new state "RUNNING" and renames the "ITER" state to "SUSPENDED". This seems like the most important one in terms of thread-safety.
  • Use CAS when closing the awaitable on a finished frame. commit
  • Close athrow awaitable when the operation completes. commit
  • Validate the athrow() argument before claiming the generator. commit
  • Document that a completed athrow() awaitable cannot be reused. commit

Full branch with commits on top of this PR branch. I'm not too familiar with the genobject.c code so the changes in that branch definitely need a second review before merging as-is.

I also found an additional thing but I'll make a new issue: logic related to ag_hooks_inited appears to be racey.

LGTM. One small suggestion, mention athrow() change also affects default buld, e.g. in NEWS:

Also make an athrow() awaitable single-use: reusing it after completion now raises :exc:RuntimeError instead of resuming the generator again.

Note: switching to '61818b6087e59de6287ac71bd734a0420d6e8ee3'.

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

⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot PPC64LE Fedora Stable 3.x (tier-2) has failed when building commit 61818b6.

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/90/builds/7478) and take a look at the build logs.
  4. Check if the failure is related to this commit (61818b6) 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/90/builds/7478

Summary of the results of the build (if available):

Click to see traceback logs 
Note: switching to '61818b6087e59de6287ac71bd734a0420d6e8ee3'.

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 61818b6087e5 gh-120321: fix thread safety of concurrently iterating over async generators (#155025)
Switched to and reset branch 'main'
