* gh-112736: Refactor del-safe symbol handling in subprocess (#112738)Russell Keith-Magee2023-12-052-24/+25
| | | | | Refactor delete-safe symbol handling in subprocess. Only module globals are force-cleared during interpreter finalization, using a class reference instead of individually listing the constants everywhere is simpler.
* GH-112727: Speed up `pathlib.Path.absolute()` (#112728)Barney Gale2023-12-042-6/+15
| | | | | | Use `_from_parsed_parts()` to create a pre-joined/pre-parsed path, rather than passing multiple arguments to `with_segments()` Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>
* gh-112334: Restore subprocess's use of `vfork()` & fix `extra_groups=[]` ↵Gregory P. Smith2023-12-043-23/+38
| | | | | | | | | | | | | | | | | | | | | behavior (#112617) Restore `subprocess`'s intended use of `vfork()` by default for performance on Linux; also fixes the behavior of `extra_groups=[]` which was unintentionally broken in 3.12.0: Fixed a performance regression in 3.12's :mod:`subprocess` on Linux where it would no longer use the fast-path ``vfork()`` system call when it could have due to a logic bug, instead falling back to the safe but slower ``fork()``. Also fixed a security bug introduced in 3.12.0. If a value of ``extra_groups=[]`` was passed to :mod:`subprocess.Popen` or related APIs, the underlying ``setgroups(0, NULL)`` system call to clear the groups list would not be made in the child process prior to ``exec()``. The security issue was identified via code inspection in the process of fixing the first bug. Thanks to @vain for the detailed report and analysis in the initial bug on Github.

| | | | | | | | | 1gig (#112615) Work around a macOS bug, limit zlib crc32 calls to 1GiB. Without this, `zlib.crc32` and `binascii.crc32` could produce incorrect results on multi-gigabyte inputs depending on the macOS version's Apple supplied zlib implementation.

| | | | | | | | | | | Change the declaration of the keywords parameter in functions PyArg_ParseTupleAndKeywords() and PyArg_VaParseTupleAndKeywords() from `char **` to `char * const *` in C and `const char * const *` in C++. It makes these functions compatible with argument of type `const char * const *`, `const char **` or `char * const *` in C++ and `char * const *` in C without explicit type cast.

* GH-106747: Improve `Path.glob()` expectations in pathlib tests (#112365)Barney Gale2023-12-031-33/+33
| | | | | | | Add trailing slashes to expected `Path.glob()` results wherever a pattern has a trailing slash. This matches what `glob.glob()` produces. Due to another bug (GH-65238) pathlib strips all trailing slashes, so this change is academic for now.

* gh-112567: Add _PyTimeFraction C API (#112568)Victor Stinner2023-12-013-107/+130
| | | | | | | | | | | | | | | | | | | | | 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 Stinner2023-12-019-125/+142
| | | | | | | | | | * 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.
