* bpo-45129 Remove deprecated reuse_address (GH-28207)Hugo van Kemenade2021-09-081-26/+0
| | | | | | | | Due to significant security concerns, the reuse_address parameter of asyncio.loop.create_datagram_endpoint, deprecated in Python 3.9, is now removed. This is because of the behavior of the socket option SO_REUSEADDR in UDP. Co-authored-by: Łukasz Langa <lukasz@langa.pl>

* bpo-43216: Remove @asyncio.coroutine (GH-26369)Illia Volochii2021-07-015-538/+64
| | | | | | | | | Remove the @asyncio.coroutine decorator enabling legacy generator-based coroutines to be compatible with async/await code; remove asyncio.coroutines.CoroWrapper used for wrapping legacy coroutine objects in the debug mode. The decorator has been deprecated since Python 3.8 and the removal was initially scheduled for Python 3.10.
* bpo-44287: asyncio test_popen() uses longer timeout (GH-26832)Victor Stinner2021-06-211-1/+2
| | | | | | | | Fix asyncio test_popen() of test_windows_utils by using a longer timeout. Use military grade battle-tested test.support.SHORT_TIMEOUT timeout rather than a hardcoded timeout of 10 seconds: it's 30 seconds by default, but it is made longer on slow buildbots. WaitForMultipleObjects() timeout argument is in milliseconds.

| | | | | | (GH-23554) asyncio.get_event_loop() emits now a deprecation warning when it creates a new event loop. In future releases it will became an alias of asyncio.get_running_loop().

| | | | | test_unix_events.py no longer checks if waitstatus_to_exitcode() mock has been called or not to make the test more functional, rather than checking the exact implementation.

| | | | | Fix test_asyncio.test_call_later() race condition: don't measure asyncio performance in the call_later() unit test. The test failed randomly on the CI.

* bpo-42140: Improve asyncio.wait function (GH-22938)Diogo Dutra2020-11-101-0/+24
| | | | | | | | | | # Improve asyncio.wait function The original code creates the futures set two times. We can create this set before, avoiding the second creation. This new behaviour [breaks the aiokafka library](https://github.com/aio-libs/aiokafka/pull/672), because it gives an iterator to that function, so the second iteration become empty.

* bpo-42183: Fix a stack overflow error for asyncio Task or Future repr() ↵Andrew Svetlov2020-11-101-0/+18
| | | | | | | | (GH-23020) The overflow occurs under some circumstances when a task or future recursively returns itself. Co-authored-by: Kyle Stanley <aeros167@gmail.com>
* bpo-38912: fix close before connect callback in test_asyncio SSL tests ↵Justin Turner Arthur2020-10-201-0/+2
| | | | | (GH-22691) Reduces the rate at which the ENV CHANGED failure occurs in test_asyncio SSL tests (due to unclosed transport), but does not 100% resolve it.

* bpo-39010: Improve test shutdown (#22066)Ben Darnell2020-09-031-3/+11
| | | | | | | Simply closing the event loop isn't enough to avoid warnings. If we don't also shut down the event loop's default executor, it sometimes logs a "dangling thread" warning. Follow-up to GH-22017

* bpo-39010: Fix errors logged on proactor loop restart (#22017)Ben Darnell2020-08-312-0/+21
| | | | | | Stopping and restarting a proactor event loop on windows can lead to spurious errors logged (ConnectionResetError while reading from the self pipe). This fixes the issue by ensuring that we don't attempt to start multiple copies of the self-pipe reading loop.
* bpo-37658: Fix asyncio.wait_for() to respect waited task status (#21894)Elvis Pranskevichus2020-08-261-0/+16
| | | | | | Currently, if `asyncio.wait_for()` itself is cancelled it will always raise `CancelledError` regardless if the underlying task is still running. This is similar to a race with the timeout, which is handled already.
* bpo-32751: Wait for task cancel in asyncio.wait_for() when timeout <= 0 (#21895)Elvis Pranskevichus2020-08-261-0/+31
| | | | | | When I was fixing bpo-32751 back in GH-7216 I missed the case when *timeout* is zero or negative. This takes care of that. Props to @aaliddell for noticing the inconsistency.

| | | | | | | | | | | | | | | recv_into instead of recv (#21442) * bpo-41273: Proactor transport read loop to use recv_into By using recv_into instead of recv we do not allocate a new buffer each time _loop_reading calls recv. This betters performance for any stream using proactor (basically any asyncio stream on windows). * bpo-41273: Double proactor read transport buffer size By doubling the read buffer size we get better performance.

| | | | | | On Linux, skip tests using multiprocessing if the current user cannot create a file in /dev/shm/ directory. Add the skip_if_broken_multiprocessing_synchronize() function to the test.support module.
* bpo-30064: Fix slow asyncio sock test (GH-20868)Fantix King2020-06-141-14/+20
| | | | | | | | | | | | | Using a log2n way to fill a much smaller buffer, and receiving in a cleaner way with EOF. The failing test was reproducible using the following command thanks to @aeros : ```bash ./python -m test test_asyncio.test_sock_lowlevel --match test_sock_client_racing -j100 -F -v ``` According to test results, we may still need to bump the timeout: https://github.com/python/cpython/blob/5aad027db9618f22f6fa2274e05dd50f928d2ed7/Lib/test/test_asyncio/test_sock_lowlevel.py#L256-L257

| | | | | | | | This updates _PyErr_ChainStackItem() to use _PyErr_SetObject() instead of _PyErr_ChainExceptions(). This prevents a hang in certain circumstances because _PyErr_SetObject() performs checks to prevent cycles in the exception context chain while _PyErr_ChainExceptions() doesn't.
