* [3.13] gh-129719: Restore missing `socket.CAN_RAW_ERR_FILTER` on Linux ↵Miss Islington (bot)2025-04-181-1/+1
| | | | | | | | | | (GH-129721) (#132702) gh-129719: Restore missing `socket.CAN_RAW_ERR_FILTER` on Linux (GH-129721) (cherry picked from commit ce31ae5209c976d28d1c21fcbb06c0ae5e50a896) Co-authored-by: Jeroen Bogers <11465689+jbogers@users.noreply.github.com> Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com> Co-authored-by: Peter Bierma <zintensitydev@gmail.com>
* [3.13] gh-132099: Harmonize Bluetooth address handling (GH-132486) (GH-132497)Serhiy Storchaka2025-04-141-22/+21
| | | | | | | | | | | Now all protocols always accept the Bluetooth address as string and getsockname() always returns the Bluetooth address as string. * BTPROTO_SCO now accepts not only bytes, but str. * BTPROTO_SCO now checks address for embedded null. * On *BSD, BTPROTO_HCI now accepts str instead of bytes. * On FreeBSD, getsockname() for BTPROTO_HCI now returns str instead of bytes. * On NetBSD and DragonFly BSD, BTPROTO_HCI now checks address for embedded null. (cherry picked from commit 1fc1df8dcc7a853b0649bc8df37cd07cbd2b6230)
* [3.13] gh-132429: Fix support of Bluetooth sockets on NetBSD and DragonFly ↵Serhiy Storchaka2025-04-121-59/+62
| | | | | | BSD (GH-132431) (GH-132458) Also fix a compiler warning on FreeBSD. (cherry picked from commit f2f86d3f459a89273ea22389bb57eed402908302)
* [3.13] gh-132075: Fix possible use of sockaddr structures with uninitialized ↵Miss Islington (bot)2025-04-041-0/+13
| | | | | | | | members (GH-132076) (GH-132086) Now all structure members are initialized with zeroes by default. (cherry picked from commit 345baa77ba2ce3b8ea8f2fad84754e5cc0b10938) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* [3.13] gh-111178: Fix getsockaddrarg() undefined behavior (#131668) (#131977)Victor Stinner2025-04-011-11/+49
| | | | | | | | | | | | gh-111178: Fix getsockaddrarg() undefined behavior (#131668) Don't pass direct references to sockaddr members since their type may not match PyArg_ParseTuple() types. Instead, use temporary 'int' and 'unsigned char' variables, and update sockaddr members afterwards. On FreeBSD, treat BTPROTO_HCI node name as a bytes string, not as an integer. (cherry picked from commit 8cd29c2b533e5a1a262238695d05f2a7c44d6455)
* [3.13] gh-126876: Fix socket internal_select() for large timeout (GH-126968) ↵Miss Islington (bot)2024-12-021-1/+4
| | | | | | | | | | | | | (#127002) gh-126876: Fix socket internal_select() for large timeout (GH-126968) If the timeout is larger than INT_MAX, replace it with INT_MAX, in the poll() code path. Add an unit test. (cherry picked from commit b3687ad454c4ac54c8599a10f3ace8a13ca48915) Co-authored-by: Victor Stinner <vstinner@python.org>
* 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-116616: Use relaxed atomic ops to access socket module defaulttimeout ↵Erlend E. Aasland2024-03-121-5/+6

* gh-110850: Use public PyTime functions (#115746)Victor Stinner2024-02-201-2/+2
| | | | | Replace private _PyTime functions with public PyTime functions. random_seed_time_pid() now reports errors to its caller.
* gh-104061: Add socket.SO_BINDTOIFINDEX constant (GH-104062)Victor Westerhuis2024-02-201-0/+3
| | | | | Add socket.SO_BINDTOIFINDEX constant This socket option avoids a race condition between SO_BINDTODEVICE and network interface renaming.
* gh-110850: Cleanup pycore_time.h includes (#115724)Victor Stinner2024-02-201-0/+1
| | | | | <pycore_time.h> include is no longer needed to get the PyTime_t type in internal header files. This type is now provided by <Python.h> include. Add <pycore_time.h> includes to C files instead.
* gh-110850: Replace _PyTime_t with PyTime_t (#115719)Victor Stinner2024-02-201-12/+12

* gh-63760: Don't declare gethostname() on Solaris (#108817)Victor Stinner2023-09-021-5/+0
| | | | | | | | | | | | | Since 2005, Solaris defines gethostname(). socketmodule.c no longer has to define gethostname() for Solaris. Oracle Solaris and OpenSolaris have patches to remove the gethostname() definition in Python: * https://github.com/oracle/solaris-userland/blob/master/components/python/python37/patches/15-gethostname.patch * https://github.com/OpenIndiana/oi-userland/blob/oi/hipster/components/python/python37/patches/15-gethostname.patch * https://github.com/omniosorg/omnios-build/blob/master/build/python27/patches/24-gethostname.patch Co-authored-by: Jakub Kulík <Kulikjak@gmail.com>

* gh-108765: Remove old prototypes from pyport.h (#108782)Victor Stinner2023-09-021-1/+5
| | | | | | | Move prototypes of gethostname(), _getpty() and struct termios from pyport.h to the C code using them: posixmodule.c, socketmodule.c and termios.c. Replace "#ifdef SOLARIS" with "#ifdef __sun".
* gh-108240: Add pycore_capsule.h internal header file (#108596)Victor Stinner2023-08-291-0/+1
| | | | Move _PyCapsule_SetTraverse() definition to a new internal header file: pycore_capsule.h.
* gh-107913: Fix possible losses of OSError error codes (GH-107930)Serhiy Storchaka2023-08-261-5/+7
| | | | | | Functions like PyErr_SetFromErrno() and SetFromWindowsErr() should be called immediately after using the C API which sets errno or the Windows error code.
* gh-108444: Replace _PyLong_AsInt() with PyLong_AsInt() (#108459)Victor Stinner2023-08-241-4/+4
| | | | | | Change generated by the command: sed -i -e 's!_PyLong_AsInt!PyLong_AsInt!g' \ $(find -name "*.c" -o -name "*.h")
* gh-106320: Remove private _PyDict functions (#108449)Victor Stinner2023-08-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Move private functions to the internal C API (pycore_dict.h): * _PyDictView_Intersect() * _PyDictView_New() * _PyDict_ContainsId() * _PyDict_DelItemId() * _PyDict_DelItem_KnownHash() * _PyDict_GetItemIdWithError() * _PyDict_GetItem_KnownHash() * _PyDict_HasSplitTable() * _PyDict_NewPresized() * _PyDict_Next() * _PyDict_Pop() * _PyDict_SetItemId() * _PyDict_SetItem_KnownHash() * _PyDict_SizeOf() No longer export most of these functions. Move also the _PyDictViewObject structure to the internal C API. Move dict_getitem_knownhash() function from _testcapi to the _testinternalcapi extension. Update test_capi.test_dict for this change.
* gh-108240: Add _PyCapsule_SetTraverse() internal function (#108339)Victor Stinner2023-08-231-6/+31
| | | | | The _socket extension uses _PyCapsule_SetTraverse() to visit and clear the socket type in the garbage collector. So the _socket.socket type can be cleared in some corner cases when it wasn't possible before.
* gh-104432: Use `memcpy()` to avoid misaligned loads (#104433)Christopher Chavez2023-07-271-5/+17
| | | | | Fix potential unaligned memory access on C APIs involving returned sequences of `char *` pointers within the :mod:`grp` and :mod:`socket` modules. These were revealed using a ``-fsaniziter=alignment`` build on ARM macOS.

* gh-102255: Use GetVersionEx instead of GetVersionExW to match argument type ↵Max Bachmann2023-03-201-1/+1
| | | | | | (GH-102583) Since we pass a structure of type `OSVERSIONINFOEX`, we need to call `GetVersionEx` instead of `GetVersionExW`.
* gh-102255: Improve build support for Windows API partitions (GH-102256)Max Bachmann2023-03-091-21/+39
| | | | | Add `MS_WINDOWS_DESKTOP`, `MS_WINDOWS_APPS`, `MS_WINDOWS_SYSTEM` and `MS_WINDOWS_GAMES` preprocessor definitions to allow switching off functionality missing from particular API partitions ("partitions" are used in Windows to identify overlapping subsets of APIs). CPython only officially supports `MS_WINDOWS_DESKTOP` and `MS_WINDOWS_SYSTEM` (APPS is included by normal desktop builds, but APPS without DESKTOP is not covered). Other configurations are a convenience for people building their own runtimes. `MS_WINDOWS_GAMES` is for the Xbox subset of the Windows API, which is also available on client OS, but is restricted compared to `MS_WINDOWS_DESKTOP`. These restrictions may change over time, as they relate to the build headers rather than the OS support, and so we assume that Xbox builds will use the latest available version of the GDK.
