* Fix typos in the Modules directory (GH-28761)Christian Clauss2021-10-071-1/+1
|
* Clean up initialization __class_getitem__ with Py_GenericAlias. (GH-28450)Serhiy Storchaka2021-09-191-2/+2
| | | | | The cast to PyCFunction is redundant. Overuse of redundant casts can hide actual bugs.
* bpo-42972: Fully implement GC protocol for re types (GH-26368)Erlend Egeberg Aasland2021-05-271-19/+81
|
* bpo-40736: Improve the error message for re.search() TypeError (GH-23312)Zackery Spytz2021-05-211-1/+2
| | | Include the invalid type in the error message.
* bpo-43916: Apply Py_TPFLAGS_DISALLOW_INSTANTIATION to selected types (GH-25748)Erlend Egeberg Aasland2021-04-301-3/+6
| | | | | | | | | | | | | | | | | | | | | Apply Py_TPFLAGS_DISALLOW_INSTANTIATION to the following types: * _dbm.dbm * _gdbm.gdbm * _multibytecodec.MultibyteCodec * _sre..SRE_Scanner * _thread._localdummy * _thread.lock * _winapi.Overlapped * array.arrayiterator * functools.KeyWrapper * functools._lru_list_elem * pyexpat.xmlparser * re.Match * re.Pattern * unicodedata.UCD * zlib.Compress * zlib.Decompress
* bpo-43908: Make re types immutable (GH-25697)Erlend Egeberg Aasland2021-04-291-3/+3

* 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-42519: Replace PyObject_MALLOC() with PyObject_Malloc() (GH-23587)Victor Stinner2020-12-011-3/+3
| | | | | | | | | No longer use deprecated aliases to functions: * Replace PyObject_MALLOC() with PyObject_Malloc() * Replace PyObject_REALLOC() with PyObject_Realloc() * Replace PyObject_FREE() with PyObject_Free() * Replace PyObject_Del() with PyObject_Free() * Replace PyObject_DEL() with PyObject_Free()
* bpo-42519: Replace PyMem_MALLOC() with PyMem_Malloc() (GH-23586)Victor Stinner2020-12-011-4/+4
| | | | | | | | | | | No longer use deprecated aliases to functions: * Replace PyMem_MALLOC() with PyMem_Malloc() * Replace PyMem_REALLOC() with PyMem_Realloc() * Replace PyMem_FREE() with PyMem_Free() * Replace PyMem_Del() with PyMem_Free() * Replace PyMem_DEL() with PyMem_Free() Modify also the PyMem_DEL() macro to use directly PyMem_Free().
* bpo-1635741: Convert _sre types to heap types and establish module state ↵Erlend Egeberg Aasland2020-11-201-198/+275
| | | | (PEP 384) (GH-23393)
* bpo-42161: Modules/ uses _PyLong_GetZero() and _PyLong_GetOne() (GH-22998)Victor Stinner2020-10-271-1/+2
| | | | | | Use _PyLong_GetZero() and _PyLong_GetOne() in Modules/ directory. _cursesmodule.c and zoneinfo.c are now built with Py_BUILD_CORE_MODULE macro defined.
* bpo-40943: Replace PY_FORMAT_SIZE_T with "z" (GH-20781)Victor Stinner2020-06-101-1/+1
| | | | | | | The PEP 353, written in 2005, introduced PY_FORMAT_SIZE_T. Python no longer supports macOS 10.4 and Visual Studio 2010, but requires more recent macOS and Visual Studio versions. In 2020 with Python 3.10, it is now safe to use directly "%zu" to format size_t and "%zi" to format Py_ssize_t.
* bpo-39943: Fix MSVC warnings in sre extension (GH-20508)Ammar Askar2020-06-011-2/+6
|
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
* bpo-39943: Add the const qualifier to pointers on non-mutable PyUnicode ↵Serhiy Storchaka2020-04-111-6/+6
| | | | data. (GH-19345)
* bpo-40170: PyObject_NEW() becomes an alias to PyObject_New() (GH-19379)Victor Stinner2020-04-071-4/+4
| | | | | | | | | | | | The PyObject_NEW() macro becomes an alias to the PyObject_New() macro, and the PyObject_NEW_VAR() macro becomes an alias to the PyObject_NewVar() macro, to hide implementation details. They no longer access directly the PyTypeObject.tp_basicsize member. Exclude _PyObject_SIZE() and _PyObject_VAR_SIZE() macros from the limited C API. Replace PyObject_NEW() with PyObject_New() and replace PyObject_NEW_VAR() with PyObject_NewVar().
* bpo-39481: Implementation for PEP 585 (#18239)Guido van Rossum2020-04-071-0/+4
| | | | | | | | | | | | This implements things like `list[int]`, which returns an object of type `types.GenericAlias`. This object mostly acts as a proxy for `list`, but has attributes `__origin__` and `__args__` that allow recovering the parts (with values `list` and `(int,)`. There is also an approximate notion of type variables; e.g. `list[T]` has a `__parameters__` attribute equal to `(T,)`. Type variables are objects of type `typing.TypeVar`.
* bpo-39573: Clean up modules and headers to use Py_IS_TYPE() function (GH-18521)Dong-hee Na2020-02-171-1/+1

* bpo-39245: Switch to public API for Vectorcall (GH-18460)Petr Viktorin2020-02-111-1/+1

* bpo-39271: Remove dead assignment from pattern_subx (GH-17915)Alex Henrie2020-01-091-1/+0

* bpo-37483: add _PyObject_CallOneArg() function (#14558)Jeroen Demeyer2019-07-041-1/+1
|
* bpo-36974: tp_print -> tp_vectorcall_offset and tp_reserved -> tp_as_async ↵Jeroen Demeyer2019-05-311-6/+6
| | | | | | | | | (GH-13464) Automatically replace tp_print -> tp_vectorcall_offset tp_compare -> tp_as_async tp_reserved -> tp_as_async

| | | | (GH-12252)
* bpo-35459: Use PyDict_GetItemWithError() instead of PyDict_GetItem(). (GH-11112)Serhiy Storchaka2019-02-251-32/+26
|
* bpo-34294: re module, fix wrong capturing groups in rare cases. (GH-11546)animalize2019-02-181-1/+1
| | | | | | Need to reset capturing groups between two SRE(match) callings in loops, this fixes wrong capturing groups in rare cases. Also add a missing index in re.rst.
* bpo-33029: Fix signatures of getter and setter functions. (GH-10746)Serhiy Storchaka2018-11-271-4/+4
| | | Fix also return type for few other functions (clear, releasebuffer).
* Simplified implementation of _sre.ascii_iscased(). (GH-9097)Sergey Fedoseev2018-09-121-6/+1
|
* bpo-34636: Use fast path for more chars in SRE category macros. (GH-9170)Sergey Fedoseev2018-09-111-3/+3
| | | | | | | When handling \s, \d, or \w (and their inverse) escapes in bytes regexes this a small but measurable performance improvement. <!-- issue-number: [bpo-34636](https://www.bugs.python.org/issue34636) --> https://bugs.python.org/issue34636 <!-- /issue-number -->
* _sre.c: Removed unused SRE_IS_ALNUM macro (GH-9090)Sergey Fedoseev2018-09-071-2/+0

* bpo-30215: Make re.compile() locale agnostic. (#1361)Serhiy Storchaka2017-05-051-0/+3
| | | | | | Compiled regular expression objects with the re.LOCALE flag no longer depend on the locale at compile time. Only the locale at matching time affects the result of matching.
* remove configure test for inline keyword (#1231)Benjamin Peterson2017-04-211-3/+1
| | | We require C99, so a configure test for this standard feature is not needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace _PyObject_CallArg1(func, arg) with PyObject_CallFunctionObjArgs(func, arg, NULL) Using the _PyObject_CallArg1() macro increases the usage of the C stack, which was unexpected and unwanted. PyObject_CallFunctionObjArgs() doesn't have this issue.

|/ / | | | | | | | | | | groupindex must a dictionary and indexgroup must be a tuple. Previously, indexgroup was a list. Use a tuple to reduce the memory usage.

* | Implement rich comparison for _sre.SRE_PatternVictor Stinner2016-11-211-6/+67
| | | | | | | | | | | | | | Issue #28727: Regular expression patterns, _sre.SRE_Pattern objects created by re.compile(), become comparable (only x==y and x!=y operators). This change should fix the issue #18383: don't duplicate warning filters when the warnings module is reloaded (thing usually only done in unit tests).
