* [3.13] gh-122907: Fix Builds Without HAVE_DYNAMIC_LOADING Set (gh-122952) ↵Miss Islington (bot)2024-12-031-4/+8
| | | | | | | | | | | (#122984) gh-122907: Fix Builds Without HAVE_DYNAMIC_LOADING Set (gh-122952) As of 529a160 (gh-118204), building with HAVE_DYNAMIC_LOADING stopped working. This is a minimal fix just to get builds working again. There are actually a number of long-standing deficiencies with HAVE_DYNAMIC_LOADING builds that need to be resolved separately.

* [3.13] gh-126914: Store the Preallocated Thread State's Pointer in a ↵Eric Snow2024-12-021-46/+46
| | | | | | | PyInterpreterState Field (gh-127114) This approach eliminates the originally reported race. It also gets rid of the deadlock reported in gh-96071, so we can remove the workaround added then. This is mostly a cherry-pick of 1c0a104 (AKA gh-126989). The difference is we add PyInterpreterState.threads_preallocated at the end of PyInterpreterState, instead of adding PyInterpreterState.threads.preallocated. That avoids ABI disruption.

* [3.13] gh-126986: Stop Using _PyInterpreterState_FailIfNotRunning() (gh-127112)Eric Snow2024-11-212-3/+6
| | | This is a pseudo-backport of d6b3e78 (gh-126988). In that change for 3.14+, we dropped _PyInterpreterState_FailIfNotRunning() and added _PyErr_SetInterpreterAlreadyRunning(). Here, we replace usage of _PyInterpreterState_FailIfNotRunning() with the inlined equivalent of _PyErr_SetInterpreterAlreadyRunning(), without adding that function. That way we avoid changing the 3.13 ABI.

| | | | | | | | | The PyMutex implementation supports unlocking after fork because we clear the list of waiters in parking_lot.c.

In that case, the string can be used by an interpreter that outlives the interpreter that created and interned it. For interpreters that share obmalloc state, also share the interned dict with the main interpreter.

| | | | | | | | | | (GH-126115) (#126130) gh-126105: Fix crash in `ast` module, when `._fields` is deleted (GH-126115) Previously, if the `ast.AST._fields` attribute was deleted, attempts to create a new `as`t node would crash due to the assumption that `_fields` always had a non-NULL value. Now it has been fixed by adding an extra check to ensure that `_fields` does not have a NULL value (this can happen when you manually remove `_fields` attribute).

| | | | | | | | | | | | | On Windows, `long` is a signed 32-bit integer so it can't represent `0xffff_ffff` without overflow. Windows exit codes are unsigned 32-bit integers, so if a child process exits with `-1`, it will be represented as `0xffff_ffff`. Also fix a number of other possible cases where `_Py_HandleSystemExit` could return with an exception set, leading to a `SystemError` (or fatal error in debug builds) later on during shutdown.

Also, don't return objects that are frozen (`gc.freeze()`) or in the process of being collected to more closely match the behavior of the default build.

| | | | | | | | | | | | | | states (GH-124459) (#125540) This fixes a crash when running the PyO3 test suite on the free-threaded build. The `qsbr` field is initialized after the `PyThreadState` is added to the interpreter's linked list -- it might still be NULL. Instead, we "steal" the queue of to-be-freed memory blocks. This is always initialized (possibly empty) and protected by the stop the world pause.
