* bpo-37445: Include FORMAT_MESSAGE_IGNORE_INSERTS in FormatMessageW() calls ↵Zackery Spytz2019-09-091-1/+2
| | | | | (GH-14462) If FormatMessageW() is passed the FORMAT_MESSAGE_FROM_SYSTEM flag without FORMAT_MESSAGE_IGNORE_INSERTS, it will fail if there are insert sequences in the message definition.
* bpo-36974: tp_print -> tp_vectorcall_offset and tp_reserved -> tp_as_async ↵Jeroen Demeyer2019-05-311-2/+2
| | | | | | | | | (GH-13464) Automatically replace tp_print -> tp_vectorcall_offset tp_compare -> tp_as_async tp_reserved -> tp_as_async
* bpo-29883: Asyncio proactor udp (GH-13440)Andrew Svetlov2019-05-281-16/+356
| | | | | | Follow-up for #1067 https://bugs.python.org/issue29883
* bpo-33895: Relase GIL while calling functions that acquire Windows loader ↵Tony Roberts2019-02-021-0/+2
| | | | | lock (GH-7789) LoadLibrary, GetProcAddress, FreeLibrary and GetModuleHandle acquire the system loader lock. Calling these while holding the GIL will cause a deadlock on the rare occasion that another thread is detaching and needs to destroy its thread state at the same time.
* bpo-32710: Fix _overlapped.Overlapped memory leaks (GH-11489)Victor Stinner2019-01-111-24/+54
| | | | | | | | | | | | Fix memory leaks in asyncio ProactorEventLoop on overlapped operation failures. Changes: * Implement the tp_traverse slot in the _overlapped.Overlapped type to help to break reference cycles and identify referrers in the garbage collector. * Always clear overlapped on failure: not only set type to TYPE_NOT_STARTED, but release also resources.
* bpo-32710: Fix leak in Overlapped_WSASend() (GH-11469)Victor Stinner2019-01-081-0/+2
| | | | | Fix a memory leak in asyncio in the ProactorEventLoop when ReadFile() or WSASend() overlapped operation fail immediately: release the internal buffer.
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-1/+1
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
* bpo-32622: Native sendfile on windows (#5565)Andrew Svetlov2018-02-251-2/+62

* asyncio: sync overlapped.c with GitHubVictor Stinner2016-04-011-0/+6
| | | | | | | | | | On Python 3.3, use aliases: * PyMem_RawMalloc = PyMem_Malloc * PyMem_RawFree = PyMem_Free These aliases are not need in Python 3.5, but this change makes synchronization of code base simpler.
* Fix usage of PyMem_Malloc() in overlapped.cVictor Stinner2016-03-161-3/+6
| | | | | | Issue #26563: Replace PyMem_Malloc() with PyMem_RawFree() since PostToQueueCallback() calls PyMem_RawFree() (previously PyMem_Free()) in a new C thread which doesn't hold the GIL.
* asyncio, _overlapped.ConnectPipe(): release the GILVictor Stinner2015-01-261-0/+3

* asyncio, Tulip issue 204: Fix IocpProactor.recv()Victor Stinner2015-01-261-2/+2
| | | | | | | | | If ReadFile() fails with ERROR_BROKEN_PIPE, the operation is not pending: don't register the overlapped. I don't know if WSARecv() can fail with ERROR_BROKEN_PIPE. Since Overlapped.WSARecv() already handled ERROR_BROKEN_PIPE, let me guess that it has the same behaviour than ReadFile().
* asyncio, Tulip issue 204: Fix IocpProactor.accept_pipe()Victor Stinner2015-01-221-2/+2
| | | | | | | | Overlapped.ConnectNamedPipe() now returns a boolean: True if the pipe is connected (if ConnectNamedPipe() failed with ERROR_PIPE_CONNECTED), False if the connection is in progress. This change removes multiple hacks in IocpProactor.
* Issue #23293, asyncio: Rewrite IocpProactor.connect_pipe()Victor Stinner2015-01-221-93/+22
| | | | | | | | Add _overlapped.ConnectPipe() which tries to connect to the pipe for asynchronous I/O (overlapped): call CreateFile() in a loop until it doesn't fail with ERROR_PIPE_BUSY. Use an increasing delay between 1 ms and 100 ms. Remove Overlapped.WaitNamedPipeAndConnect() which is no more used.
* Issue #23095, asyncio: Rewrite _WaitHandleFuture.cancel()Victor Stinner2015-01-211-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change fixes a race conditon related to _WaitHandleFuture.cancel() leading to Python crash or "GetQueuedCompletionStatus() returned an unexpected event" logs. Before, the overlapped object was destroyed too early, it was possible that the wait completed whereas the overlapped object was already destroyed. Sometimes, a different overlapped was allocated at the same address, leading to unexpected completition. _WaitHandleFuture.cancel() now waits until the wait is cancelled to clear its reference to the overlapped object. To wait until the cancellation is done, UnregisterWaitEx() is used with an event instead of UnregisterWait(). To wait for this event, a new _WaitCancelFuture class was added. It's a simplified version of _WaitCancelFuture. For example, its cancel() method calls UnregisterWait(), not UnregisterWaitEx(). _WaitCancelFuture should not be cancelled. The overlapped object is kept alive in _WaitHandleFuture until the wait is unregistered. Other changes: * Add _overlapped.UnregisterWaitEx() * Remove fast-path in IocpProactor.wait_for_handle() to immediatly set the result if the wait already completed. I'm not sure that it's safe to call immediatly UnregisterWaitEx() before the completion was signaled. * Add IocpProactor._unregistered() to forget an overlapped which may never be signaled, but may be signaled for the next loop iteration. It avoids to block forever IocpProactor.close() if a wait was cancelled, and it may also avoid some "... unexpected event ..." warnings.
