* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-031-0/+1
| | | | | | | | | | | | | | This PR adds the ability to enable the GIL if it was disabled at interpreter startup, and modifies the multi-phase module initialization path to enable the GIL when loading a module, unless that module's spec includes a slot indicating it can run safely without the GIL. PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148. A warning will be issued up to once per interpreter for the first GIL-using module that is loaded. If `-v` is given, a shorter message will be printed to stderr every time a GIL-using module is loaded (including the first one that issues a warning).

* gh-107913: Fix possible losses of OSError error codes (GH-107930)Serhiy Storchaka2023-08-261-1/+2
| | | | | | Functions like PyErr_SetFromErrno() and SetFromWindowsErr() should be called immediately after using the C API which sets errno or the Windows error code.
* gh-106320: Remove private _PyLong converter functions (#108499)Victor Stinner2023-08-261-1/+4
| | | | | | | | | | | Move these private functions to the internal C API (pycore_long.h): * _PyLong_UnsignedInt_Converter() * _PyLong_UnsignedLongLong_Converter() * _PyLong_UnsignedLong_Converter() * _PyLong_UnsignedShort_Converter() Argument Clinic now emits #include "pycore_long.h" when these functions are used.

| | | | | Use PyModule_Add() or PyModule_AddObjectRef() instead of soft deprecated PyModule_AddObject().
* gh-105156: Argument Clinic avoids Py_UNICODE type (#105161)Victor Stinner2023-05-311-4/+4
| | | | Argument Clinic now uses "const wchar_t*" type instead of "const Py_UNICODE*" type for the "Py_UNICODE" format.
* gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)Eric Snow2023-05-051-0/+1
| | | Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).

* bpo-39148: enable ipv6 for datagrams in Proactor (GH-19121)Kjell Braden2020-05-181-5/+2
| | | | | | Ifdef is not necessary, as AF_INET6 is supported from Windows Vista, and other code in overlapped.c uses AF_INET6 and is not ifdef'd. Change the raised exception so users are not fooled to think it comes from Windows API. Automerge-Triggered-By: @njsmith
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.

* 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, 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.
