* 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.

* 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.

* bpo-33654: Support BufferedProtocol in set_protocol() and start_tls() (GH-7130)Yury Selivanov2018-05-281-0/+4
| | | | | | | | | | | In this commit: * Support BufferedProtocol in set_protocol() and start_tls() * Fix proactor to cancel readers reliably * Update tests to be compatible with OpenSSL 1.1.1 * Clarify BufferedProtocol docs * Bump TLS tests timeouts to 60 seconds; eliminate possible race from start_serving * Rewrite test_start_tls_server_1

* bpo-32166: Drop Python 3.4 code from asyncio (#4612)Andrew Svetlov2017-11-291-49/+9
| | | | | | | | | | | | | | | | | | | | | | * Drop Python 3.4 code from asyncio * Fix notes * Add missing imports * Restore comment * Resort imports * Drop Python 3.4-3.5 specific code * Drop redunant check * Fix tests * Restore _COROUTINE_TYPES order * Remove useless code
* bpo-32154: Remove asyncio.selectors (#4605)Victor Stinner2017-11-281-1/+1
| | | | | | | | | | | | * Remove asyncio.selectors and asyncio._overlapped symbols from the namespace of the asyncio module * Replace "from asyncio import selectors" with "import selectors" * Replace "from asyncio import _overlapped" with "import _overlapped" asyncio.selectors was added to support Python 3.3, which doesn't have selectors in its standard library, and Python 3.4 in the same code base. Same rationale for asyncio._overlapped. Python 3.3 reached its end of life, and asyncio is no more maintained as a third party module on PyPI.
* asyncio: use directly socket.socketpair() (#4597)Victor Stinner2017-11-281-4/+1
