| | | | | | | | | | (#111991) Fix undefined behaviour in datetime.time.fromisoformat() (GH-111982) Fix undefined behaviour in datetime.time.fromisoformat() when parsing a string without a timezone. 'tzoffset' is not assigned to by parse_isoformat_time if it returns 0, but time_fromisoformat then passes tzoffset to another function, which is undefined behaviour (even if the function in question does not use the value).

| | | | | | | | | | | | | | | | | | | (#109668) gh-109613: _pystat_fromstructstat() checks for exceptions (#109618) Fix os.stat() and os.DirEntry.stat(): check for exceptions. Previously, on Python built in debug mode, these functions could trigger a fatal Python error (and abort the process) when a function succeeded with an exception set. _pystat_fromstructstat() now exits immediately if an exception is raised, rather only checking for exceptions at the end. It fix following fatal error in fill_time(): Fatal Python error: _Py_CheckSlotResult: Slot * of type int succeeded with an exception set (cherry picked from commit d4cea794a7b9b745817d2bd982d35412aef04710)

| | | | | | | | | | | | | | | | | | | (#109272) gh-108987: Fix _thread.start_new_thread() race condition (#109135) Fix _thread.start_new_thread() race condition. If a thread is created during Python finalization, the newly spawned thread now exits immediately instead of trying to access freed memory and lead to a crash. thread_run() calls PyEval_AcquireThread() which checks if the thread must exit. The problem was that tstate was dereferenced earlier in _PyThreadState_Bind() which leads to a crash most of the time. Move _PyThreadState_CheckConsistency() from thread_run() to _PyThreadState_Bind(). (cherry picked from commit 517cd82ea7d01b344804413ef05610934a43a241)

* [3.11] gh-104372: Drop the GIL around the vfork() call. (#104782) (#104958)Gregory P. Smith2023-09-011-2/+19
| | | | | | | | | | | | | gh-104372: Drop the GIL around the vfork() call. (#104782) On Linux where the `subprocess` module can use the `vfork` syscall for faster spawning, prevent the parent process from blocking other threads by dropping the GIL while it waits for the vfork'ed child process `exec` outcome. This prevents spawning a binary from a slow filesystem from blocking the rest of the application. Fixes #104372. (cherry picked from commit d08679212d9af52dd074cd4a6abb440edb944c9c)
