bpo-44114: Fix dictkeys_reversed and dictvalues_reversed function signatures (GH-26062)

2021-05-13T08:17:07+00:00

These are passed and called as PyCFunction, however they are defined here without the (ignored) args parameter.

This works fine in some C compilers, but fails in webassembly or anything else that has strict function pointer call type checking.

bpo-43977: Use tp_flags for collection matching (GH-25723)

2021-04-30T08:50:28+00:00

* Add Py_TPFLAGS_SEQUENCE and Py_TPFLAGS_MAPPING, add to all relevant standard builtin classes.

* Set relevant flags on collections.abc.Sequence and Mapping.

* Use flags in MATCH_SEQUENCE and MATCH_MAPPING opcodes.

* Inherit Py_TPFLAGS_SEQUENCE and Py_TPFLAGS_MAPPING.

* Add NEWS

* Remove interpreter-state map_abc and seq_abc fields.

bpo-43770: Refactor type_new() function (GH-25325)

2021-04-10T21:15:32+00:00

* Split type_new() into into many small functions.
* Add type_new_ctx structure to pass variables between subfunctions.
* Initialize some PyTypeObject and PyHeapTypeObject members earlier
  in type_new_alloc().
* Rename variables to more specific names.
* Add "__weakref__" identifier for type_new_visit_slots().
* Factorize code to convert a method to a classmethod
  (__init_subclass__ and __class_getitem__).
* Add braces to respect PEP 7.
* Move variable declarations where the variables are initialized.

bpo-42093: Cleanup _PyDict_GetItemHint() (GH-24582)

2021-02-21T11:02:04+00:00

* No longer save/restore the current exception. It is no longer used
  with an exception raised.
* No longer clear the current exception on error: it's now up to the
  caller.

bpo-43277: Add PySet_CheckExact to the C-API (GH-24598)

2021-02-20T18:03:08+00:00

For some mysterious reason we have PySet_Check, PyFrozenSet_Check, PyAnySet_Check, PyAnySet_CheckExact and PyFrozenSet_CheckExact but no PySet_CheckExact.

bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)

2021-02-19T14:10:45+00:00

Pass the current interpreter (interp) rather than the current Python
thread state (tstate) to internal functions which only use the
interpreter.

Modified functions:

* _PyXXX_Fini() and _PyXXX_ClearFreeList() functions
* _PyEval_SignalAsyncExc(), make_pending_calls()
* _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str()
* should_audit(), set_flags_from_config(), make_flags()
* _PyAtExit_Call()
* init_stdio_encoding()
* etc.

bpo-42536: GC track recycled tuples (GH-23623)

2020-12-05T03:45:57+00:00

Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector:

- collections.OrderedDict.items
- dict.items
- enumerate
- functools.reduce
- itertools.combinations
- itertools.combinations_with_replacement
- itertools.permutations
- itertools.product
- itertools.zip_longest
- zip

Previously, they could have become untracked by a prior garbage collection.
