* gh-110850: Remove _PyTime_TimeUnchecked() function (#118552)Victor Stinner2024-05-051-26/+2
| | | | | | | | | | | | | Use the new public Raw functions: * _PyTime_PerfCounterUnchecked() with PyTime_PerfCounterRaw() * _PyTime_TimeUnchecked() with PyTime_TimeRaw() * _PyTime_MonotonicUnchecked() with PyTime_MonotonicRaw() Remove internal functions: * _PyTime_PerfCounterUnchecked() * _PyTime_TimeUnchecked() * _PyTime_MonotonicUnchecked()
* gh-110850: Fix _PyTime_FromSecondsDouble() API (#116606)Victor Stinner2024-03-111-2/+4
| | | | | | | | Return 0 on success. Set an exception and return -1 on error. Fix os.timerfd_settime(): properly report exceptions on _PyTime_FromSecondsDouble() failure. No longer export _PyTime_FromSecondsDouble().
* gh-110850: Cleanup PyTime API: PyTime_t are nanoseconds (#115753)Victor Stinner2024-02-211-9/+4
| | | | | | | | | | PyTime_t no longer uses an arbitrary unit, it's always a number of nanoseconds (64-bit signed integer). * Rename _PyTime_FromNanosecondsObject() to _PyTime_FromLong(). * Rename _PyTime_AsNanosecondsObject() to _PyTime_AsLong(). * Remove pytime_from_nanoseconds(). * Remove pytime_as_nanoseconds(). * Remove _PyTime_FromNanoseconds().
* gh-110850: Replace private _PyTime_MAX with public PyTime_MAX (#115751)Victor Stinner2024-02-211-5/+1
| | | | | | | Remove references to the old names _PyTime_MIN and _PyTime_MAX, now that PyTime_MIN and PyTime_MAX are public. Replace also _PyTime_MIN with PyTime_MIN.
* gh-110850: Use public PyTime functions (#115746)Victor Stinner2024-02-201-1/+0
| | | | | Replace private _PyTime functions with public PyTime functions. random_seed_time_pid() now reports errors to its caller.
* gh-110850: Rename internal PyTime C API functions (#115734)Victor Stinner2024-02-201-32/+18
| | | | | | | | | | | | | | | | | Rename functions: * _PyTime_GetSystemClock() => _PyTime_TimeUnchecked() * _PyTime_GetPerfCounter() => _PyTime_PerfCounterUnchecked() * _PyTime_GetMonotonicClock() => _PyTime_MonotonicUnchecked() * _PyTime_GetSystemClockWithInfo() => _PyTime_TimeWithInfo() * _PyTime_GetMonotonicClockWithInfo() => _PyTime_MonotonicWithInfo() * _PyTime_GetMonotonicClockWithInfo() => _PyTime_MonotonicWithInfo() Changes: * Remove "typedef PyTime_t PyTime_t;" which was "typedef PyTime_t _PyTime_t;" before a previous rename. * Update comments of "Unchecked" functions. * Remove invalid PyTime_Time() comment.
* gh-110850: Replace _PyTime_t with PyTime_t (#115719)Victor Stinner2024-02-201-37/+37
| | | | | Run command: sed -i -e 's!\<_PyTime_t\>!PyTime_t!g' $(find -name "*.c" -o -name "*.h")
* gh-110850: Add PyTime_t C API (GH-115215)Petr Viktorin2024-02-121-48/+51
| | | | | | | | | | | | * gh-110850: Add PyTime_t C API Add PyTime_t API: * PyTime_t type. * PyTime_MIN and PyTime_MAX constants. * PyTime_AsSecondsDouble(), PyTime_Monotonic(), PyTime_PerfCounter() and PyTime_GetSystemClock() functions. Co-authored-by: Victor Stinner <vstinner@python.org>
* gh-112567: Add _PyTimeFraction C API (#112568)Victor Stinner2023-12-011-7/+26
| | | | | | | | | | | | | | | | | | | | | Use a fraction internally in the _PyTime API to reduce the risk of integer overflow: simplify the fraction using Greatest Common Divisor (GCD). The fraction API is used by time functions: perf_counter(), monotonic() and process_time(). For example, QueryPerformanceFrequency() usually returns 10 MHz on Windows 10 and newer. The fraction SEC_TO_NS / frequency = 1_000_000_000 / 10_000_000 can be simplified to 100 / 1. * Add _PyTimeFraction type. * Add functions: * _PyTimeFraction_Set() * _PyTimeFraction_Mul() * _PyTimeFraction_Resolution() * No longer check "numer * denom <= _PyTime_MAX" in _PyTimeFraction_Set(). _PyTimeFraction_Mul() uses _PyTime_Mul() which handles integer overflow.
* gh-112567: Add _Py_GetTicksPerSecond() function (#112587)Victor Stinner2023-12-011-10/+0
| | | | | | | | | | * Move _PyRuntimeState.time to _posixstate.ticks_per_second and time_module_state.ticks_per_second. * Add time_module_state.clocks_per_second. * Rename _PyTime_GetClockWithInfo() to py_clock(). * Rename _PyTime_GetProcessTimeWithInfo() to py_process_time(). * Add process_time_times() helper function, called by py_process_time(). * os.times() is now always built: no longer rely on HAVE_TIMES.
* gh-108277: Add os.timerfd_create() function (#108382)Masaru Tsuchiyama2023-10-071-1/+5
| | | | | | | | Add wrapper for timerfd_create, timerfd_settime, and timerfd_gettime to os module.

* gh-107211: No longer export PyTime internal functions (#108422)Victor Stinner2023-08-241-118/+146
| | | | | | | | | No longer export these 2 internal C API functions: * _PyTime_AsNanoseconds() * _PyTime_GetSystemClockWithInfo() Change comment style to "// comment" and add comment explaining why other functions have to be exported.
* gh-107211: No longer export internal functions (3) (#107215)Victor Stinner2023-07-251-0/+2
| | | | | | | | | | | | | | | | | | No longer export these 14 internal C API functions: * _PySys_Audit() * _PySys_SetAttr() * _PyTraceBack_FromFrame() * _PyTraceBack_Print_Indented() * _PyUnicode_FormatAdvancedWriter() * _PyUnicode_ScanIdentifier() * _PyWarnings_Init() * _Py_DumpASCII() * _Py_DumpDecimal() * _Py_DumpHexadecimal() * _Py_DumpTraceback() * _Py_DumpTracebackThreads() * _Py_WriteIndent() * _Py_WriteIndentedMargin()
* gh-106316: Remove pytime.h header file (#106317)Victor Stinner2023-07-011-0/+312
| | | | | | | | | | | | | | | | | Remove the "cpython/pytime.h" header file: it only contained private functions. Move functions to the internal pycore_time.h header file. Move tests from _testcapi to _testinternalcapi. Rename also test methods to have the same name than tested C functions. No longer export these functions: * _PyTime_Add() * _PyTime_As100Nanoseconds() * _PyTime_FromMicrosecondsClamp() * _PyTime_FromTimespec() * _PyTime_FromTimeval() * _PyTime_GetPerfCounterWithInfo() * _PyTime_MulDiv()
* gh-81057: Move time Globals to _PyRuntimeState (gh-100122)Eric Snow2022-12-081-0/+25
