GH-95736: fix IsolatedAsyncioTestCase to set event loop before calling setup functions #95898

kumaraditya303 · 2022-08-11T18:18:44Z

Issue: IsolatedAsyncioTestCase does not call asyncio.set_event_loop before setUp anymore, asyncio.Runner+PidFdChildWatcher leaves zombie processes #95736

Lib/test/test_unittest/test_async_case.py

This is waiting for a resolution of #95900 (comment).

Lib/unittest/async_case.py

…ttest

gvanrossum

Okay this is what I had in mind so LGTM from that perspective, but we need to get a better understanding of what Thomas is asking about the event loop policy.

gvanrossum · 2022-08-16T00:10:06Z

So we've established that in tests deriving from IsolatedAsyncioTestCase, the runner isn't fully initialized yet when setUp is called. (The issue should have that in its topic or at least in the body of the first comment.)

It makes me wonder if the Runner class shouldn't initialize itself eagerly (rather than lazily), but that's way too big a change for 3.11 and there's probably a good reason -- though we've now seen it also causes problems.

@kumaraditya303 Can you shorten the test per my remarks previously in this issue?

I'd also like to invite @serhiy-storchaka to review this, since he did some work on async_case.py just 3 months ago.

Lib/unittest/async_case.py

In general the solution LGTM, but I have a lot of questions about testing code.

Can you shorten the test per my remarks previously in this issue?

Done, FTR the previous test was mostly copied from #95736

serhiy-storchaka

LGTM.

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 -

Urm, the WebAssembly buildbot failures are actually due to our test. We need to fix this before we can backport. Apparently by forcing a call to new_event_loop() we are forcing a call to socket.socketpair() which doesn't work on WASM. I don't know what the magic incantation is to skip a test on WASM. I'll ask on Discord.
