* GH-94597: add deprecation warnings for subclassing `AbstractChildWatcher` ↵Kumar Aditya2022-11-121-0/+7
| | | | (#99386)
* GH-98327: Reduce scope of catch_warnings() in _make_subprocess_transport ↵Kumar Aditya2022-10-171-24/+25
| | | | | (#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.

* GH-94182: Run the PidfdChildWatcher on the running loop (#94184)Thomas Grainger2022-10-081-32/+12
| | | | | | | | There is no reason for this watcher to be attached to any particular loop. This should make it safe to use regardless of the lifetime of the event loop running in the main thread (relative to other loops).

* Revert "gh-87079: Warn on unintended signal wakeup fd override in `asyncio` ↵Guido van Rossum2022-09-171-16/+3
| | | | | | | (#96807)" (#96898) This reverts commit 05878106989c6f5b9dd35a6c15a21bee59312827. Reason: This broke buildbots (some warnings added by that commit are turned to errors in the SSL buildbot). Repro: ./python Lib/test/ssltests.py
* gh-87079: Warn on unintended signal wakeup fd override in `asyncio` (#96807)Michel Hidalgo2022-09-171-3/+16
| | | Warn on loop initialization, when setting the wakeup fd disturbs a previously set wakeup fd, and on loop closing, when upon resetting the wakeup fd, we find it has been changed by someone else.

* bpo-43945: [Enum] reduce scope of new format() behavior (GH-26752)Ethan Furman2021-06-181-2/+2
| | | | | | | | | | | | | | | | | | | | | * [Enum] reduce scope of new format behavior Instead of treating all Enums the same for format(), only user mixed-in enums will be affected. In other words, IntEnum and IntFlag will not be changing the format() behavior, due to the requirement that they be drop-in replacements of existing integer constants. If a user creates their own integer-based enum, then the new behavior will apply: class Grades(int, Enum): A = 5 B = 4 C = 3 D = 2 F = 0 Now: format(Grades.B) -> DeprecationWarning and '4' 3.12: -> no warning, and 'B'

* bpo-43989: Add signal format specifier for unix_events (GH-25769)Roberto Hueso2021-05-011-2/+2

* bpo-40364: asyncio uses os.waitstatus_to_exitcode() (GH-23798)Victor Stinner2020-12-161-19/+15
| | | | | 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.

* bpo-38356: Fix ThreadedChildWatcher thread leak in test_asyncio (GH-16552)Kyle Stanley2020-01-121-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Motivation for this PR (comment from @vstinner in bpo issue): ``` Warning seen o AMD64 Ubuntu Shared 3.x buildbot: https://buildbot.python.org/all/#/builders/141/builds/2593 test_devnull_output (test.test_a=syncio.test_subprocess.SubprocessThreadedWatcherTests) ... Warning -- threading_cleanup() failed to cleanup 1 threads (count: 1, dangling: 2) ``` The following implementation details for the new method are TBD: 1) Public vs private 2) Inclusion in `close()` 3) Name 4) Coroutine vs subroutine method 5) *timeout* parameter If it's a private method, 3, 4, and 5 are significantly less important. I started with the most minimal implementation that fixes the dangling threads without modifying the regression tests, which I think is particularly important. I typically try to avoid directly modifying existing tests as much as possible unless it's necessary to do so. However, I am open to changing any part of this. https://bugs.python.org/issue38356
* bpo-38982: Fix asyncio PidfdChildWatcher on waitpid() error (GH-17477)Victor Stinner2019-12-061-2/+13
| | | | | | If waitpid() is called elsewhere, waitpid() call fails with ChildProcessError: use return code 255 in this case, and log a warning. It ensure that the pidfd file descriptor is closed if this error occurs.
* bpo-38951: Use threading.main_thread() check in asyncio (GH-17433)Hill Ma2019-12-051-3/+2
| | | https://bugs.python.org/issue38951
* Remove binding of captured exceptions when not used to reduce the chances of ↵Pablo Galindo2019-11-191-2/+2
| | | | | | | creating cycles (GH-17246) Capturing exceptions into names can lead to reference cycles though the __traceback__ attribute of the exceptions in some obscure cases that have been reported previously and fixed individually. As these variables are not used anyway, we can remove the binding to reduce the chances of creating reference cycles. See for example GH-13135

* bpo-32528: Make asyncio.CancelledError a BaseException. (GH-13528)Yury Selivanov2019-05-271-5/+15
| | | | | | | | | | | | | | | This will address the common mistake many asyncio users make: an "except Exception" clause breaking Tasks cancellation. In addition to this change, we stop inheriting asyncio.TimeoutError and asyncio.InvalidStateError from their concurrent.futures.* counterparts. There's no point for these exceptions to share the inheritance chain. In 3.9 we'll focus on implementing supervisors and cancel scopes, which should allow better handling of all exceptions, including SystemExit and KeyboardInterrupt
* bpo-35721: Close socket pair if Popen in _UnixSubprocessTransport fails ↵Niklas Fiekas2019-05-201-6/+12
| | | | | | | | (GH-11553) This slightly expands an existing test case `test_popen_error` to trigger a `ResourceWarning` and fixes it. https://bugs.python.org/issue35721
* asyncio: __del__() keep reference to warnings.warn (GH-11491)Victor Stinner2019-01-101-6/+4
| | | | | | | | | | | | | | | * asyncio: __del__() keep reference to warnings.warn The __del__() methods of asyncio classes now keep a strong reference to the warnings.warn() to be able to display the ResourceWarning warning in more cases. Ensure that the function remains available if instances are destroyed late during Python shutdown (while module symbols are cleared). * Rename warn parameter to _warn "_warn" name is a hint that it's not the regular warnings.warn() function.
