* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541

* bpo-46417: time module uses PyStructSequence_NewType() (GH-30734)Victor Stinner2022-01-211-37/+81
| | | | | | | | | | The time module now creates its struct_time type as a heap type using PyStructSequence_NewType(), rather than using a static type. * Add a module state to the time module: add traverse, clear and free functions. * Use PyModule_AddType(). * Remove the 'initialized' variable.

* bpo-21302: time.sleep() uses waitable timer on Windows (GH-28483)Victor Stinner2021-09-221-43/+110
| | | | | | | | | | | | On Windows, time.sleep() now uses a waitable timer which has a resolution of 100 ns (10^-7 sec). Previously, it had a solution of 1 ms (10^-3 sec). * On Windows, time.sleep() now calls PyErr_CheckSignals() before resetting the SIGINT event. * Add _PyTime_As100Nanoseconds() function. * Complete and update time.sleep() documentation. Co-authored-by: Livius <egyszeregy@freemail.hu>
* bpo-21302: Add _PyTime_AsNanoseconds() (GH-28350)Victor Stinner2021-09-151-8/+8
| | | | | | | | | | | | | | | | | Refactor pytime.c: * Add pytime_from_nanoseconds() and pytime_as_nanoseconds(), and use explicitly these functions * Add two empty lines between functions * PEP 7: add braces { ... } * C99: declare variables where they are set * Rename private functions to lowercase * Rename error_time_t_overflow() to pytime_time_t_overflow() * Rename win_perf_counter_frequency() to py_win_perf_counter_frequency() * py_get_monotonic_clock(): add an assertion to detect overflow when mach_absolute_time() unsigned uint64_t is casted to _PyTime_t (signed int64_t). _testcapi: use _PyTime_FromNanoseconds().
* bpo-21302: Add clock_nanosleep() implementation for time.sleep() (GH-28111)Livius2021-09-131-5/+31
| | | | | | In Unix operating systems, time.sleep() now uses the clock_nanosleep() function, if available, which allows to sleep for an interval specified with nanosecond precision. Co-authored-by: Victor Stinner <vstinner@python.org>
* bpo-37205: time.time() cannot fail with fatal error (GH-23314)Victor Stinner2020-11-161-22/+65
| | | | | | | | | | | | | | | time.time(), time.perf_counter() and time.monotonic() functions can no longer fail with a Python fatal error, instead raise a regular Python exception on failure. Remove _PyTime_Init(): don't check system, monotonic and perf counter clocks at startup anymore. On error, _PyTime_GetSystemClock(), _PyTime_GetMonotonicClock() and _PyTime_GetPerfCounter() now silently ignore the error and return 0. They cannot fail with a Python fatal error anymore. Add py_mach_timebase_info() and win_perf_counter_frequency() sub-functions.

| | | | | | | (GH-19381) On AIX, time.thread_time() is now implemented with thread_cputime() which has nanosecond resolution, rather than clock_gettime(CLOCK_THREAD_CPUTIME_ID) which has a resolution of 10 ms.

* bpo-36779: time.tzname returns empty string on Windows if default cod… ↵Paul Monson2019-06-121-0/+14
| | | | | | | | | | | | | | | (GH-13073) Calling setlocale(LC_CTYPE, "") on a system where GetACP() returns CP_UTF8 results in empty strings in _tzname[]. This causes time.tzname to be an empty string. I have reported the bug to the UCRT team and will follow up, but it will take some time get a fix into production. In the meantime one possible workaround is to temporarily change the locale by calling setlocale(LC_CTYPE, "C") before calling _tzset and restore the current locale after if the GetACP() == CP_UTF8 or CP_UTF7 @zooba https://bugs.python.org/issue36779
* bpo-36895: remove time.clock() as per removal notice. (GH-13270)Matthias Bussonnier2019-05-131-50/+0

Other changes: * mktime(): rename variable 'buf' to 'tm'. * _PyTime_localtime(): * Use "localtime" rather than "ctime" in the error message (specific to AIX). * Always initialize errno to 0 just in case if localtime_r() doesn't set errno on error. * On AIX, avoid abs() which is limited to int type. * EINVAL constant is now always available.

* bpo-35373: Fix PyInit_time() error handling (GH-10865)Victor Stinner2018-12-031-4/+7
| | | | | | | * PyInit_time() now returns NULL if an exception is raised. * Rename PyInit_timezone() to init_timezone(). "PyInit_" prefix is a special prefix for function initializing a module. init_timezone() doesn't initialize a module and the function is not exported.

The first edition of this change (afde1c1a05cc8a1e8adf6403c451f6708509a605) failed (bpo-34715) because FreeBSD doesn't define the timezone globals. That's why we're now checking for HAVE_DECL_TZNAME.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Modify locale.localeconv(), time.tzname, os.strerror() and other functions to ignore the UTF-8 Mode: always use the current locale encoding. Changes: * Add _Py_DecodeLocaleEx() and _Py_EncodeLocaleEx(). On decoding or encoding error, they return the position of the error and an error message which are used to raise Unicode errors in PyUnicode_DecodeLocale() and PyUnicode_EncodeLocale(). * Replace _Py_DecodeCurrentLocale() with _Py_DecodeLocaleEx(). * PyUnicode_DecodeLocale() now uses _Py_DecodeLocaleEx() for all cases, especially for the strict error handler. * Add _Py_DecodeUTF8Ex(): return more information on decoding error and supports the strict error handler. * Rename _Py_EncodeUTF8_surrogateescape() to _Py_EncodeUTF8Ex(). * Replace _Py_EncodeCurrentLocale() with _Py_EncodeLocaleEx(). * Ignore the UTF-8 mode to encode/decode localeconv(), strerror() and time zone name. * Remove PyUnicode_DecodeLocale(), PyUnicode_DecodeLocaleAndSize() and PyUnicode_EncodeLocale() now ignore the UTF-8 mode: always use the "current" locale. * Remove _PyUnicode_DecodeCurrentLocale(), _PyUnicode_DecodeCurrentLocaleAndSize() and _PyUnicode_EncodeCurrentLocale().
