* gh-82300: Add track parameter to multiprocessing.shared_memory (#110778)pan3242023-12-054-23/+106
| | | | | | | | | | Add a track parameter to shared memory to allow resource tracking via the side-launched resource tracker process to be disabled on platforms that use it (POSIX). This allows people who do not want automated cleanup at process exit because they are using the shared memory with processes not participating in Python's resource tracking to use the shared_memory API.

* 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

* 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
