* [3.13] gh-129502: Fix handling errors in ctypes callbacks (GH-129504) (#129517)Miss Islington (bot)2025-02-041-36/+30
| | | | | | | | | | | | gh-129502: Fix handling errors in ctypes callbacks (GH-129504) Unlikely errors in preparing arguments for ctypes callback are now handled in the same way as errors raised in the callback of in converting the result of the callback -- using sys.unraisablehook() instead of sys.excepthook() and not setting sys.last_exc and other variables.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#126861) For dlsym(), a return value of NULL does not necessarily indicate an error [1]. Therefore, to avoid using stale (or NULL) dlerror() values, we must: 1. clear the previous error state by calling dlerror() 2. call dlsym() 3. call dlerror() If the return value of dlerror() is not NULL, an error occured. In ctypes we choose to treat a NULL return value from dlsym() as a "not found" error. This is the same as the fallback message we use on Windows, Cygwin or when getting/formatting the error reason fails.

* [3.13] gh-126688: Reinit import lock after fork (GH-126692) (GH-126765)Miss Islington (bot)2024-11-121-0/+1
| | | | | | | | | The PyMutex implementation supports unlocking after fork because we clear the list of waiters in parking_lot.c. This doesn't work as well for _PyRecursiveMutex because on some systems, such as SerenityOS, the thread id is not preserved across fork().
