* gh-110014: Fix _POSIX_THREADS and _POSIX_SEMAPHORES usage (#110139)Victor Stinner2023-09-301-4/+5
| | | | | | | | | | | | | | | | * pycore_pythread.h is now the central place to make sure that _POSIX_THREADS and _POSIX_SEMAPHORES macros are defined if available. * Make sure that pycore_pythread.h is included when _POSIX_THREADS and _POSIX_SEMAPHORES macros are tested. * PY_TIMEOUT_MAX is now defined as a constant, since its value depends on _POSIX_THREADS, instead of being defined as a macro. * Prevent integer overflow in the preprocessor when computing PY_TIMEOUT_MAX_VALUE on Windows: replace "0xFFFFFFFELL * 1000 < LLONG_MAX" with "0xFFFFFFFELL < LLONG_MAX / 1000". * Document the change and give hints how to fix affected code. * Add an exception for PY_TIMEOUT_MAX name to smelly.py * Add PY_TIMEOUT_MAX to the stable ABI

* gh-74953: _PyThread_cond_after() uses _PyTime_t (#94056)Victor Stinner2022-06-211-26/+13
| | | | | | pthread _PyThread_cond_after() implementation now uses the _PyTime_t type to handle properly overflow: clamp to the maximum value. Remove MICROSECONDS_TO_TIMESPEC() function.
* gh-74953: Reformat PyThread_acquire_lock_timed() (#93947)Victor Stinner2022-06-191-46/+62
| | | | | | | | Reformat the pthread implementation of PyThread_acquire_lock_timed() using a mutex and a conditioinal variable. * Add goto to avoid multiple indentation levels and exit quickly * Use "while(1)" and make the control flow more obvious. * PEP 7: Add braces around if blocks.

* gh-88750: Remove the PYTHONTHREADDEBUG env var support. (#92509)Gregory P. Smith2022-05-091-19/+0
| | | | Remove the `PYTHONTHREADDEBUG` env var support. Remove no-op dprintf() macro calls.
* bpo-46008: Move thread-related interpreter state into a sub-struct. (gh-29971)Eric Snow2021-12-071-4/+4
| | | | | This parallels _PyRuntimeState.interpreters. Doing this helps make it more clear what part of PyInterpreterState relates to its threads. https://bugs.python.org/issue46008
* bpo-41710: Add private _PyDeadline_Get() function (GH-28674)Victor Stinner2021-10-011-10/+8
| | | | | | | | Add a private C API for deadlines: add _PyDeadline_Init() and _PyDeadline_Get() functions. * Add _PyTime_Add() and _PyTime_Mul() functions which compute t1+t2 and t1*t2 and clamp the result on overflow. * _PyTime_MulDiv() now uses _PyTime_Add() and _PyTime_Mul().
* bpo-41710: PyThread_acquire_lock_timed() uses sem_clockwait() (GH-28662)Victor Stinner2021-10-011-6/+33
| | | | | | | | | On Unix, if the sem_clockwait() function is available in the C library (glibc 2.30 and newer), the threading.Lock.acquire() method now uses the monotonic clock (time.CLOCK_MONOTONIC) for the timeout, rather than using the system clock (time.CLOCK_REALTIME), to not be affected by system clock changes. configure now checks if the sem_clockwait() function is available.
* bpo-41710: PyThread_acquire_lock_timed() clamps the timout (GH-28643)Victor Stinner2021-09-301-29/+34
| | | | | | | | | | | | | | | | | | | PyThread_acquire_lock_timed() now clamps the timeout into the [_PyTime_MIN; _PyTime_MAX] range (_PyTime_t type) if it is too large, rather than calling Py_FatalError() which aborts the process. PyThread_acquire_lock_timed() no longer uses MICROSECONDS_TO_TIMESPEC() to compute sem_timedwait() argument, but _PyTime_GetSystemClock() and _PyTime_AsTimespec_truncate(). Fix _thread.TIMEOUT_MAX value on Windows: the maximum timeout is 0x7FFFFFFF milliseconds (around 24.9 days), not 0xFFFFFFFF milliseconds (around 49.7 days). Set PY_TIMEOUT_MAX to 0x7FFFFFFF milliseconds, rather than 0xFFFFFFFF milliseconds. Fix PY_TIMEOUT_MAX overflow test: replace (us >= PY_TIMEOUT_MAX) with (us > PY_TIMEOUT_MAX).
* bpo-41710: Add _PyTime_AsTimespec_clamp() (GH-28629)Victor Stinner2021-09-301-5/+1
| | | | | | | | | | | | | | | Add the _PyTime_AsTimespec_clamp() function: similar to _PyTime_AsTimespec(), but clamp to _PyTime_t min/max and don't raise an exception. PyThread_acquire_lock_timed() now uses _PyTime_AsTimespec_clamp() to remove the Py_UNREACHABLE() code path. * Add _PyTime_AsTime_t() function. * Add PY_TIME_T_MIN and PY_TIME_T_MAX constants. * Replace _PyTime_AsTimeval_noraise() with _PyTime_AsTimeval_clamp(). * Add pytime_divide_round_up() function. * Fix integer overflow in pytime_divide(). * Add pytime_divmod() function.

* bpo-40268: Rename _PyInterpreterState_GET_UNSAFE() (GH-19509)Victor Stinner2020-04-141-2/+2
| | | | | | | Rename _PyInterpreterState_GET_UNSAFE() to _PyInterpreterState_GET() for consistency with _PyThreadState_GET() and to have a shorter name (help to fit into 80 columns). Add also "assert(tstate != NULL);" to the function.
* bpo-40268: Include explicitly pycore_interp.h (GH-19505)Victor Stinner2020-04-141-0/+1
| | | | pycore_pystate.h no longer includes pycore_interp.h: it's now included explicitly in files accessing PyInterpreterState.
* bpo-40089: Add _at_fork_reinit() method to locks (GH-19195)Victor Stinner2020-04-071-0/+20
| | | | | | | | | | | | | | | Add a private _at_fork_reinit() method to _thread.Lock, _thread.RLock, threading.RLock and threading.Condition classes: reinitialize the lock after fork in the child process; reset the lock to the unlocked state. Rename also the private _reset_internal_locks() method of threading.Event to _at_fork_reinit(). * Add _PyThread_at_fork_reinit() private function. It is excluded from the limited C API. * threading.Thread._reset_internal_locks() now calls _at_fork_reinit() on self._tstate_lock rather than creating a new Python lock object.
* Use calloc-based functions, not malloc. (GH-19152)Andy Lester2020-03-251-2/+1

* bpo-18049: Sync thread stack size to main thread size on macOS (GH-14748)Ronald Oussoren2019-08-011-1/+2
| | | | | | This changeset increases the default size of the stack for threads on macOS to the size of the stack of the main thread and reenables the relevant recursion test.
* bpo-37077: Add native thread ID (TID) for AIX (GH-13624)Michael Felt2019-06-131-2/+7

* bpo-33015: Fix UB in pthread PyThread_start_new_thread (GH-6008)Siddhesh Poyarekar2018-11-301-4/+36
| | | | | | | Fix an undefined behaviour in the pthread implementation of PyThread_start_new_thread(): add a function wrapper to always return NULL. Add pythread_callback struct and pythread_wrapper() to thread_pthread.h.
* bpo-35081: Add _PyThreadState_GET() internal macro (GH-10266)Victor Stinner2018-11-011-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | If Py_BUILD_CORE is defined, the PyThreadState_GET() macro access _PyRuntime which comes from the internal pycore_state.h header. Public headers must not require internal headers. Move PyThreadState_GET() and _PyInterpreterState_GET_UNSAFE() from Include/pystate.h to Include/internal/pycore_state.h, and rename PyThreadState_GET() to _PyThreadState_GET() there. The PyThreadState_GET() macro of pystate.h is now redefined when pycore_state.h is included, to use the fast _PyThreadState_GET(). Changes: * Add _PyThreadState_GET() macro * Replace "PyThreadState_GET()->interp" with _PyInterpreterState_GET_UNSAFE() * Replace PyThreadState_GET() with _PyThreadState_GET() in internal C files (compiled with Py_BUILD_CORE defined), but keep PyThreadState_GET() in the public header files. * _testcapimodule.c: replace PyThreadState_GET() with PyThreadState_Get(); the module is not compiled with Py_BUILD_CORE defined. * pycore_state.h now requires Py_BUILD_CORE to be defined.
* bpo-32593: Drop FreeBSD 9 and older support (#5232)Victor Stinner2018-01-221-10/+0
| | | Drop support of FreeBSD 9 and older.
* Replace KB unit with KiB (#4293)Victor Stinner2017-11-081-1/+1
| | | | | | | | | | | kB (*kilo* byte) unit means 1000 bytes, whereas KiB ("kibibyte") means 1024 bytes. KB was misused: replace kB or KB with KiB when appropriate. Same change for MB and GB which become MiB and GiB. Change the output of Tools/iobench/iobench.py. Round also the size of the documentation from 5.5 MB to 5 MiB.
* bpo-30768: Recompute timeout on interrupted lock (GH-4103)Victor Stinner2017-10-241-6/+49
| | | | | | | | | | | | | | | | Fix the pthread+semaphore implementation of PyThread_acquire_lock_timed() when called with timeout > 0 and intr_flag=0: recompute the timeout if sem_timedwait() is interrupted by a signal (EINTR). See also the PEP 475. The pthread implementation of PyThread_acquire_lock() now fails with a fatal error if the timeout is larger than PY_TIMEOUT_MAX, as done in the Windows implementation. The check prevents any risk of overflow in PyThread_acquire_lock(). Add also PY_DWORD_MAX constant.
* bpo-25658: Implement PEP 539 for Thread Specific Storage (TSS) API (GH-1362)Masayuki Yamamoto2017-10-061-3/+87

| | | | | | | | | | | | | | | | * bpo-30832: Remove own implementation for thread-local storage CPython has provided the own implementation for thread-local storage (TLS) on Python/thread.c, it's used in the case which a platform has not supplied native TLS. However, currently all supported platforms (NT and pthreads) have provided native TLS and defined the Py_HAVE_NATIVE_TLS macro with unconditional in any case. * bpo-30832: replace NT with Windows * bpo-30832: change to directive chain * bpo-30832: remove comemnt which making no sense
* bpo-30765: Avoid blocking when PyThread_acquire_lock() is asked not to (#2403)Antoine Pitrou2017-06-261-45/+50
| | | | | | | | | | | * bpo-30765: Avoid blocking when PyThread_acquire_lock() is asked not to lock This is especially important if PyThread_acquire_lock() is called reentrantly (for example from a signal handler). * Update 2017-06-26-14-29-50.bpo-30765.Q5iBmf.rst * Avoid core logic when taking the mutex failed
