| | | | | | | | (#106099) [3.12] gh-105987: Fix reference counting issue in `_asyncio._swap_current_task` (GH-105989). (cherry picked from commit d2cbb6e918d9ea39f0dd44acb53270f2dac07454) Co-authored-by: chgnrdv <52372310+chgnrdv@users.noreply.github.com>

* gh-103793: Defer formatting task name (#103767)Itamar Ostricher2023-04-291-0/+12
| | | | | | | | | | | | | The default task name is "Task-<counter>" (if no name is passed in during Task creation). This is initialized in `Task.__init__` (C impl) using string formatting, which can be quite slow. Actually using the task name in real world code is not very common, so this is wasted init. Let's defer this string formatting to the first time the name is read (in `get_name` impl), so we don't need to pay the string formatting cost if the task name is never read. We don't change the order in which tasks are assigned numbers (if they are) -- the number is set on task creation, as a PyLong instead of a formatted string.

* gh-83925: Make asyncio.subprocess communicate similar to non-asyncio (#18650)Marek Marczykowski-Górecki2023-04-281-0/+18
| | | | | | | 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.

* GH-84559: Deprecate fork being the multiprocessing default. (#100618)Gregory P. Smith2023-02-021-1/+8
| | | | | | | | This starts the process. Users who don't specify their own start method and use the default on platforms where it is 'fork' will see a DeprecationWarning upon multiprocessing.Pool() construction or upon multiprocessing.Process.start() or concurrent.futures.ProcessPool use. See the related issue and documentation within this change for details.

* gh-93453: No longer create an event loop in get_event_loop() (#98440)Serhiy Storchaka2022-12-066-130/+62
| | | | | | | | | | | | | | | 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.

| | | Such buildbots (at the time of writing, only "AMD64 RHEL8 FIPS Only Blake2 Builtin Hash 3.x") cannot use multiprocessing with a fork server, so just skip the test there.
* GH-79033: Fix asyncio.Server.wait_closed() (#98582)Guido van Rossum2022-11-242-1/+28
| | | | | | | | | | | 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
