* gh-83925: Make asyncio.subprocess communicate similar to non-asyncio (#18650)Marek Marczykowski-Górecki2023-04-281-5/+6
| | | | | | | subprocess's communicate(None) closes stdin of the child process, after sending no (extra) data. Make asyncio variant do the same. This fixes issues with processes that waits for EOF on stdin before continuing.

| | | | | | | | | | Partially revert changes made in GH-93453. asyncio.DefaultEventLoopPolicy.get_event_loop() now emits a DeprecationWarning and creates and sets a new event loop instead of raising a RuntimeError if there is no current event loop set.

* gh-93453: No longer create an event loop in get_event_loop() (#98440)Serhiy Storchaka2022-12-064-23/+9
| | | | | | | | | | | | | | | asyncio.get_event_loop() now always return either running event loop or the result of get_event_loop_policy().get_event_loop() call. The latter should now raise an RuntimeError if no current event loop was set instead of creating and setting a new event loop. It affects also a number of asyncio functions and constructors which call get_event_loop() implicitly: ensure_future(), shield(), gather(), etc. DeprecationWarning is no longer emitted if there is no running event loop but the current event loop was set.

* GH-79033: Fix asyncio.Server.wait_closed() (#98582)Guido van Rossum2022-11-241-1/+1
| | | | | | | | | | | It was a no-op when used as recommended (after close()). I had to debug one test (test__sock_sendfile_native_failure) -- the cleanup sequence for the test fixture was botched. Hopefully that's not a portend of problems in user code -- this has never worked so people may well be doing this wrong. :-( Co-authored-by: kumar aditya

| | | | | (#98333) Alas, warnings.catch_warnings() has global scope, not thread scope, so this is still not perfect, but it reduces the time during which warnings are ignored. Better solution welcome.
* GH-94597: Deprecate child watcher getters and setters (#98215)Kumar Aditya2022-10-151-24/+32
| | | | | | | This is the next step for deprecating child watchers. Until we've removed the API completely we have to use it, so this PR is mostly suppressing a lot of warnings when using the API internally. Once the child watcher API is totally removed, the two child watcher implementations we actually use and need (Pidfd and Thread) will be turned into internal helpers.
