* gh-117657: Acquire a critical section around `SemLock.__{enter,exit}__` ↵mpage2024-05-091-2/+4
| | | | | | (#118812) These methods are purely wrappers around `Semlock.{acquire,release}`, which expect a critical section to be held.
* gh-117435: Make `SemLock` thread-safe in free-threaded build (#117436)Sam Gross2024-04-041-5/+10
| | | | Use critical sections to make acquire, release, and _count thread-safe without the GIL.
* gh-108765: Python.h no longer includes <sys/time.h> (#108775)Victor Stinner2023-09-021-0/+4
| | | | | | | | | Python.h no longer includes <time.h>, <sys/select.h> and <sys/time.h> standard header files. * Add <time.h> include to xxsubtype.c. * Add <sys/time.h> include to posixmodule.c and semaphore.c. * readline.c includes <sys/select.h> instead of <sys/time.h>. * resource.c no longer includes <time.h> and <sys/time.h>.
* gh-107913: Fix possible losses of OSError error codes (GH-107930)Serhiy Storchaka2023-08-261-4/+5
| | | | | | Functions like PyErr_SetFromErrno() and SetFromWindowsErr() should be called immediately after using the C API which sets errno or the Windows error code.
* gh-106869: Use new PyMemberDef constant names (#106871)Victor Stinner2023-07-251-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Remove '#include "structmember.h"'. * If needed, add <stddef.h> to get offsetof() function. * Update Parser/asdl_c.py to regenerate Python/Python-ast.c. * Replace: * T_SHORT => Py_T_SHORT * T_INT => Py_T_INT * T_LONG => Py_T_LONG * T_FLOAT => Py_T_FLOAT * T_DOUBLE => Py_T_DOUBLE * T_STRING => Py_T_STRING * T_OBJECT => _Py_T_OBJECT * T_CHAR => Py_T_CHAR * T_BYTE => Py_T_BYTE * T_UBYTE => Py_T_UBYTE * T_USHORT => Py_T_USHORT * T_UINT => Py_T_UINT * T_ULONG => Py_T_ULONG * T_STRING_INPLACE => Py_T_STRING_INPLACE * T_BOOL => Py_T_BOOL * T_OBJECT_EX => Py_T_OBJECT_EX * T_LONGLONG => Py_T_LONGLONG * T_ULONGLONG => Py_T_ULONGLONG * T_PYSSIZET => Py_T_PYSSIZET * T_NONE => _Py_T_NONE * READONLY => Py_READONLY * PY_AUDIT_READ => Py_AUDIT_READ * READ_RESTRICTED => Py_AUDIT_READ * PY_WRITE_RESTRICTED => _Py_WRITE_RESTRICTED * RESTRICTED => (READ_RESTRICTED | _Py_WRITE_RESTRICTED)
* bpo-15999: Accept arbitrary values for boolean parameters. (#15609)Serhiy Storchaka2022-12-031-6/+6
| | | builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.
* GH-94382: port multiprocessing static types to heap types (#94336)Kumar Aditya2022-07-201-40/+31
|
* GH-94736: Fix _multiprocessing.SemLock subclassing (#94738)Kumar Aditya2022-07-111-4/+2

* bpo-45847: Fix _multiprocessing on platforms without sem_open (GH-29833)Christian Heimes2021-11-291-0/+4
|
* bpo-42519: Replace PyObject_MALLOC() with PyObject_Malloc() (GH-23587)Victor Stinner2020-12-011-1/+1
| | | | | | | | | No longer use deprecated aliases to functions: * Replace PyObject_MALLOC() with PyObject_Malloc() * Replace PyObject_REALLOC() with PyObject_Realloc() * Replace PyObject_FREE() with PyObject_Free() * Replace PyObject_Del() with PyObject_Free() * Replace PyObject_DEL() with PyObject_Free()
* bpo-20175: Convert Modules/_multiprocessing to the Argument Clinic (GH-14245)Zackery Spytz2020-07-121-69/+175
|
* bpo-39511: Fix multiprocessing semlock_acquire() (GH-18298)Victor Stinner2020-02-011-10/+11
| | | | The Python C API must not be used when the GIL is released: only access Py_None when the GIL is hold.
* 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-36254: Fix invalid uses of %d in format strings in C. (GH-12264)Serhiy Storchaka2019-03-131-1/+1
|
* bpo-35436: Add missing PyErr_NoMemory() calls and other minor bug fixes. ↵Zackery Spytz2018-12-071-3/+6
| | | | | | (GH-11015) Set MemoryError when appropriate, add missing failure checks, and fix some potential leaks.
* bpo-33012: Fix invalid function cast warnings with gcc 8. (GH-6749)Serhiy Storchaka2018-11-271-2/+2
| | | | | | Fix invalid function cast warnings with gcc 8 for method conventions different from METH_NOARGS, METH_O and METH_VARARGS excluding Argument Clinic generated code.
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-5/+5
| | | | | | | | | (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-31653: Remove deadcode in semlock_acquire() (#4091)Victor Stinner2017-10-231-4/+4
| | | | | | | | | | Fix the following Coverity warning: >>> CID 1420038: Control flow issues (DEADCODE) >>> Execution cannot reach this statement: "res = sem_trywait(self->han...". 321 res = sem_trywait(self->handle); The deadcode was introduced by the commit c872d39d324cd6f1a71b73e10406bbaed192d35f.

* bpo-6532: Make the thread id an unsigned integer. (#781)Serhiy Storchaka2017-03-231-1/+1
| | | | | | | | | | | * bpo-6532: Make the thread id an unsigned integer. From C API side the type of results of PyThread_start_new_thread() and PyThread_get_thread_ident(), the id parameter of PyThreadState_SetAsyncExc(), and the thread_id field of PyThreadState changed from "long" to "unsigned long". * Restore a check in thread_get_ident().
