* gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)Eric Snow2023-05-051-0/+1
| | | Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).
* gh-102255: Improve build support for Windows API partitions (GH-102256)Max Bachmann2023-03-091-1/+7
| | | | | 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.
* gh-81057: Fix an ifdef in the time module (#100125)Eric Snow2022-12-091-2/+4
| | | | | An earlier commit only defined check_ticks_per_second() when HAVE_TIMES is defined. However, we also need it when HAVE_CLOCK is defined. This primarily affects Windows. https://github.com/python/cpython/issues/81057

* gh-93741: Add private C API _PyImport_GetModuleAttrString() (GH-93742)Serhiy Storchaka2022-06-141-7/+2
| | | | | | It combines PyImport_ImportModule() and PyObject_GetAttrString() and saves 4-6 lines of code on every use. Add also _PyImport_GetModuleAttr() which takes Python strings as arguments.

* 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.
* bpo-41100: Support macOS 11 and Apple Silicon (GH-22855)Ronald Oussoren2020-11-081-52/+162
| | | | | | | | | | | Co-authored-by: Lawrence D’Anna <lawrence_danna@apple.com> * Add support for macOS 11 and Apple Silicon (aka arm64) As a side effect of this work use the system copy of libffi on macOS, and remove the vendored copy * Support building on recent versions of macOS while deploying to older versions This allows building installers on macOS 11 while still supporting macOS 10.9.

| | | | | | | (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-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-151-6/+5

* 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
| | | | `time.clock()` was deprecated in 3.3, and marked for removal removal in 3.8; this thus remove it from the time module.

| | | | | | | | | | | | | | | Fix time.mktime() error handling on AIX for year before 1970. 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.
* bpo-35373: Fix PyInit_timezone() if HAVE_DECL_TZNAME is defined (GH-10861)Victor Stinner2018-12-031-4/+5
