* gh-110964: Remove private _PyArg functions (#110966)Victor Stinner2023-10-171-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the following private functions and structures to pycore_modsupport.h internal C API: * _PyArg_BadArgument() * _PyArg_CheckPositional() * _PyArg_NoKeywords() * _PyArg_NoPositional() * _PyArg_ParseStack() * _PyArg_ParseStackAndKeywords() * _PyArg_Parser structure * _PyArg_UnpackKeywords() * _PyArg_UnpackKeywordsWithVararg() * _PyArg_UnpackStack() * _Py_ANY_VARARGS() Changes: * Python/getargs.h now includes pycore_modsupport.h to export functions. * clinic.py now adds pycore_modsupport.h when one of these functions is used. * Add pycore_modsupport.h includes when a C extension uses one of these functions. * Define Py_BUILD_CORE_MODULE in C extensions which now include directly or indirectly (via code generated by Argument Clinic) pycore_modsupport.h: * _csv * _curses_panel * _dbm * _gdbm * _multiprocessing.posixshmem * _sqlite.row * _statistics * grp * resource * syslog * _testcapi: bad_get() no longer uses METH_FASTCALL calling convention but METH_VARARGS. Replace _PyArg_UnpackStack() with PyArg_ParseTuple(). * _testcapi: add PYTESTCAPI_NEED_INTERNAL_API macro which is defined by _testcapi sub-modules which need the internal C API (pycore_modsupport.h): exceptions.c, float.c, vectorcall.c, watchers.c. * Remove Include/cpython/modsupport.h header file. Include/modsupport.h no longer includes the removed header file. * Fix mypy clinic.py
* gh-107603: Argument Clinic: Only include pycore_gc.h if needed (#108726)Victor Stinner2023-08-311-7/+1
| | | | | | | | | | | | | | | | | | | | Argument Clinic now only includes pycore_gc.h if PyGC_Head is needed, and only includes pycore_runtime.h if _Py_ID() is needed. * Add 'condition' optional argument to Clinic.add_include(). * deprecate_keyword_use() includes pycore_runtime.h when using the _PyID() function. * Fix rendering of includes: comments start at the column 35. * Mark PC/clinic/_wmimodule.cpp.h and "Objects/stringlib/clinic/*.h.h" header files as generated in .gitattributes. Effects: * 42 header files generated by AC no longer include the internal C API, instead of 4 header files before. For example, Modules/clinic/_abc.c.h no longer includes the internal C API. * Fix _testclinic_depr.c.h: it now always includes pycore_runtime.h to get _Py_ID().
* gh-90928: Statically Initialize the Keywords Tuple in Clinic-Generated Code ↵Eric Snow2022-08-111-1/+7
| | | | | | | | | | | | | | | | (gh-95860) We only statically initialize for core code and builtin modules. Extension modules still create the tuple at runtime. We'll solve that part of interpreter isolation separately. This change includes generated code. The non-generated changes are in: * Tools/clinic/clinic.py * Python/getargs.c * Include/cpython/modsupport.h * Makefile.pre.in (re-generate global strings after running clinic) * very minor tweaks to Modules/_codecsmodule.c and Python/Python-tokenize.c All other changes are generated code (clinic, global strings).
* gh-91320: Argument Clinic uses _PyCFunction_CAST() (#32210)Victor Stinner2022-05-031-4/+4
| | | | Replace "(PyCFunction)(void(*)(void))func" cast with _PyCFunction_CAST(func).
* bpo-35582: Argument Clinic: Optimize the "all boring objects" case. (GH-11520)Serhiy Storchaka2019-01-111-10/+10
| | | | | Use _PyArg_CheckPositional() and inlined code instead of PyArg_UnpackTuple() and _PyArg_UnpackStack() if all parameters are positional and use the "object" converter.
* bpo-33012: Fix invalid function cast warnings with gcc 8 in Argument Clinic. ↵Serhiy Storchaka2018-11-271-4/+4
| | | | | | | | (GH-6748) Fix invalid function cast warnings with gcc 8 for method conventions different from METH_NOARGS, METH_O and METH_VARARGS in Argument Clinic generated code.
* bpo-31333: Re-implement ABCMeta in C (#5273)Ivan Levkivskyi2018-02-181-0/+162
This adds C versions of methods used by ABCMeta that improve performance of various ABC operations.
