* bpo-43977: Properly update the tp_flags of existing subclasses when their ↵Brandt Bucher2021-06-251-6/+31
| | | | parents are registered (GH-26864)
* bpo-43977: Make sure that tp_flags for pattern matching are inherited ↵Mark Shannon2021-05-021-2/+9
| | | | correctly. (GH-25813)
* bpo-43977: Use tp_flags for collection matching (GH-25723)Mark Shannon2021-04-301-0/+33
| | | | | | | | | | | | | * 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-40137: Add pycore_moduleobject.h internal header (GH-25507)Victor Stinner2021-04-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add pycore_moduleobject.h internal header file with static inline functions to access module members: * _PyModule_GetDict() * _PyModule_GetDef() * _PyModule_GetState() These functions don't check at runtime if their argument has a valid type and can be inlined even if Python is not built with LTO. _PyType_GetModuleByDef() uses _PyModule_GetDef(). Replace PyModule_GetState() with _PyModule_GetState() in the extension modules, considered as performance sensitive: * _abc * _functools * _operator * _pickle * _queue * _random * _sre * _struct * _thread * _winapi * array * posix The following extensions are now built with the Py_BUILD_CORE_MODULE macro defined, to be able to use the internal pycore_moduleobject.h header: _abc, array, _operator, _queue, _sre, _struct.
* bpo-42157: Convert unicodedata.UCD to heap type (GH-22991)Victor Stinner2020-10-261-8/+8
| | | | | | | Convert the unicodedata extension module to the multiphase initialization API (PEP 489) and convert the unicodedata.UCD static type to a heap type. Co-Authored-By: Mohamed Koubaa <koubaa.m@gmail.com>
* bpo-40217: Ensure Py_VISIT(Py_TYPE(self)) is always called for ↵Pablo Galindo2020-05-271-0/+1
| | | | | | | | | PyType_FromSpec types (reverts GH-19414) (GH-20264) Heap types now always visit the type in tp_traverse. See added docs for details. This reverts commit 0169d3003be3d072751dd14a5c84748ab63a249f. Automerge-Triggered-By: @encukou

* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+0
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-40149: Implement traverse in _abc._abc_data (GH-19412)Victor Stinner2020-04-071-4/+22
| | | Implement traverse and clear slots in _abc._abc_data type.
* bpo-40077: Convert _abc module to use PyType_FromSpec() (GH-19202)Dong-hee Na2020-03-301-30/+75
| | | | | | | Replace statically allocated types with heap allocated types: use PyType_FromSpec(). Add a module state to store the _abc_data_type. Add traverse, clear and free functions to the module.
* bpo-1635741: Port _abc extension to multiphase initialization (PEP 489) ↵Hai Shi2020-02-171-9/+18
| | | | (GH-18030)

* Fix misleading mentions of tp_size in comments (GH-9093)Peter Eisentraut2018-09-101-1/+1
| | | | Many type object initializations labeled a field "tp_size" in the comment, but the name of that field is tp_basicsize.
* bpo-34441: Fix ABC.__subclasscheck__ crash on classes with invalid ↵Alexey Izbyshev2018-08-201-0/+3
| | | | | | __subclasses__ (GH-8835) The missing NULL check was reported by Svace static analyzer.

* bpo-33018: Improve issubclass() error checking and message. (GH-5944)jab2018-03-221-0/+5
| | | | | This improves error message for situations when a non-class is checked w.r.t. an abstract base class.
* bpo-32999: Fix ABC.__subclasscheck__ crash (GH-6002)INADA Naoki2018-03-071-12/+25
