Use "PyObject*", instead of "PyTypeObject*", for `@classmethod`
functions to fix an undefined behavior.

gh-117657: Acquire a critical section around SemLock.__{enter,exit}__ (#118812)
These methods are purely wrappers around `Semlock.{acquire,release}`,
which expect a critical section to be held.

gh-111089: Use PyUnicode_AsUTF8() in Argument Clinic (#111585)
Replace PyUnicode_AsUTF8AndSize() with PyUnicode_AsUTF8() to remove
the explicit check for embedded null characters.

The change avoids to have to include explicitly <string.h> to get the
strlen() function when using a recent version of the limited C API.

gh-110964: Remove private _PyArg functions (#110966)
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)
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-108444: Argument Clinic uses PyLong_AsInt() (#108458)
Argument Clinic now uses the new public PyLong_AsInt(), rather than
the old name _PyLong_AsInt().

bpo-15999: Accept arbitrary values for boolean parameters. (#15609)
builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.

gh-90928: Improve static initialization of keywords tuple in AC (#95907) 2022-08-13 12:09:40 +02:00

gh-90928: Statically Initialize the Keywords Tuple in Clinic-Generated Code (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).
