* gh-89850: Add default C implementations of persistent_id() and ↵Serhiy Storchaka2024-01-102-211/+151
| | | | | | | | | | | persistent_load() (GH-113579) Previously the C implementation of pickle.Pickler and pickle.Unpickler classes did not have such methods and they could only be used if they were overloaded in subclasses or set as instance attributes. Fixed calling super().persistent_id() and super().persistent_load() in subclasses of the C implementation of pickle.Pickler and pickle.Unpickler classes. It no longer causes an infinite recursion.

| | | | | (GH-113786) Based on patch by SilentGhost.
* gh-112182: Replace StopIteration with RuntimeError for future (#113220)Jamie Phan2024-01-101-5/+20
| | | | | | When an `StopIteration` raises into `asyncio.Future`, this will cause a thread to hang. This commit address this by not raising an exception and silently transforming the `StopIteration` with a `RuntimeError`, which the caller can reconstruct from `fut.exception().__cause__`

* gh-113750: Fix object resurrection in free-threaded builds (gh-113751)Sam Gross2024-01-061-3/+1
| | | | | | | | | gh-113750: Fix object resurrection on free-threaded builds This avoids the undesired re-initializing of fields like `ob_gc_bits`, `ob_mutex`, and `ob_tid` when an object is resurrected due to its finalizer being called. This change has no effect on the default (with GIL) build.
* gh-113688: Split up gcmodule.c (gh-113715)Sam Gross2024-01-051-1959/+32
| | | | | This splits part of Modules/gcmodule.c of into Python/gc.c, which now contains the core garbage collection implementation. The Python module remain in the Modules/gcmodule.c file.

* gh-113536: Expose `os.waitid` on macOS (#113542)Ronald Oussoren2024-01-012-10/+10
| | | | | | | | | * gh-113536: Expose `os.waitid` on macOS This API has been available on macOS for a long time, but was explicitly excluded due to unspecified problems with the API in ancient versions of macOS. * Document that the API is available on macOS starting in Python 3.13
* gh-62260: Fix ctypes.Structure subclassing with multiple layers (GH-13374)Jeffrey Kintscher2024-01-012-6/+6
| | | | | | | | | | | The length field of StgDictObject for Structure class contains now the total number of items in ffi_type_pointer.elements (excluding the trailing null). The old behavior of using the number of elements in the parent class can cause the array to be truncated when it is copied, especially when there are multiple layers of subclassing.

| | | | | | | | | | First fix resolve situation when pyexpat module (which contains expat_CAPI capsule) deallocates before _elementtree, so we need to hold a strong reference to pyexpat module to. Second fix resolve situation when module state is deallocated before deallocation of XMLParser instances, which uses module state to clear some stuff.
