* bpo-46613: Add PyType_GetModuleByDef to the public API (GH-31081)Petr Viktorin2022-02-111-1/+1
| | | | | * Make PyType_GetModuleByDef public (remove underscore) Co-authored-by: Victor Stinner <vstinner@python.org>
* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
* bpo-43908: Make heap types converted during 3.10 alpha immutable (GH-26351)Erlend Egeberg Aasland2021-06-171-5/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Make functools types immutable * Multibyte codec types are now immutable * pyexpat.xmlparser is now immutable * array.arrayiterator is now immutable * _thread types are now immutable * _csv types are now immutable * _queue.SimpleQueue is now immutable * mmap.mmap is now immutable * unicodedata.UCD is now immutable * sqlite3 types are now immutable * _lsprof.Profiler is now immutable * _overlapped.Overlapped is now immutable * _operator types are now immutable * winapi__overlapped.Overlapped is now immutable * _lzma types are now immutable * _bz2 types are now immutable * _dbm.dbm and _gdbm.gdbm are now immutable

| | | | | | | | | | | | | | | | | | | | | 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-42866: Add traverse func to _multibytecodec.MultibyteCodec (GH-24166)Victor Stinner2021-01-081-3/+13
| | | | Convert _multibytecodec.MultibyteCodec type to a GC type and adds a traverse function.
* bpo-42866: Fix refleak in CJK getcodec() (GH-24165)Victor Stinner2021-01-081-0/+1
| | | Fix a reference leak in the getcodec() function of CJK codecs.
* bpo-42846: Convert CJK codec extensions to multiphase init (GH-24157)Victor Stinner2021-01-071-29/+39
| | | | | | | | | | | Convert the 6 CJK codec extension modules (_codecs_cn, _codecs_hk, _codecs_iso2022, _codecs_jp, _codecs_kr and _codecs_tw) to the multiphase initialization API (PEP 489). Remove getmultibytecodec() local cache: always import _multibytecodec. It should be uncommon to get a codec. For example, this function is only called once per CJK codec module. Fix a reference leak in register_maps() error path.

* bpo-37999: No longer use __int__ in implicit integer conversions. (GH-15636)Serhiy Storchaka2020-05-261-11/+1
| | | | Only __index__ should be used to make integer conversions lossless.

| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.

* bpo-38631: Avoid Py_FatalError() in _multibytecodec init (GH-17233)Victor Stinner2019-11-181-1/+0
| | | | | If an exception is raised and PyInit__multibytecodec() returns NULL, Python reports properly the exception to the user. There is no need to crash Python with Py_FatalError().
* bpo-37206: Unrepresentable default values no longer represented as None. ↵Serhiy Storchaka2019-09-141-4/+4
| | | | | | | (GH-13933) In ArgumentClinic, value "NULL" should now be used only for unrepresentable default values (like in the optional third parameter of getattr). "None" should be used if None is accepted as argument and passing None has the same effect as not passing the argument at all.

| | | | | | | | | Fixed the following compiler warning in multibytecodec.c: warning C4244: '=': conversion from 'Py_ssize_t' to 'unsigned char', possible loss of data Cast Py_ssize_t to unsigned char: the maximum value is checked on the previous line.
* bpo-35194: Fix a wrong constant in cp932 codec (GH-10420)Alexey Izbyshev2018-11-091-1/+1
| | | | | | | | | | | This typo doesn't affect the result because wrong bits are discarded on implicit conversion to unsigned char, but it trips UBSan with -fsanitize=implicit-integer-truncation. https://bugs.python.org/issue35194
* bpo-33578: Fix getstate/setstate for CJK decoder (GH-10290)Christopher Thorne2018-11-021-5/+22
| | | | Previous version was casting to Py_ssize_t incorrectly and exhibited unexpected behavior on big-endian systems.
* bpo-33578: Add getstate/setstate for CJK codec (GH-6984)Christopher Thorne2018-11-014-22/+273
| | | | | | | | This implements getstate and setstate for the cjkcodecs multibyte incremental encoders/decoders, primarily to fix issues with seek/tell. The encoder getstate/setstate is slightly tricky as the "state" is pending bytes + MultibyteCodec_State but only an integer can be returned. The approach I've taken is to encode this data into a long, similar to how .tell() encodes a "cookie_type" as a long. https://bugs.python.org/issue33578
