* gh-110964: Remove private _PyArg functions (#110966)Victor Stinner2023-10-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Stinner2023-08-311-5/+4
| | | | | | | | | | | | | | | | | | | | 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-106320: Remove private AC converter functions (#108505)Victor Stinner2023-08-261-1/+2
| | | | | | | | | | | | | | Move these private functions to the internal C API (pycore_abstract.h): * _Py_convert_optional_to_ssize_t() * _PyNumber_Index() Argument Clinic now emits #include "pycore_abstract.h" when these functions are used. The parser of the c-analyzer tool now uses a list of files which use the limited C API, rather than a list of files using the internal C API.
* gh-108444: Argument Clinic uses PyLong_AsInt() (#108458)Victor Stinner2023-08-241-11/+11
| | | | Argument Clinic now uses the new public PyLong_AsInt(), rather than the old name _PyLong_AsInt().
* gh-95534: Improve gzip reading speed by 10% (#97664)Ruben Vorderman2022-10-171-1/+99
| | | | | | | | | Change summary: + There is now a `gzip.READ_BUFFER_SIZE` constant that is 128KB. Other programs that read in 128KB chunks: pigz and cat. So this seems best practice among good programs. Also it is faster than 8 kb chunks. + a zlib._ZlibDecompressor was added. This is the _bz2.BZ2Decompressor ported to zlib. Since the zlib.Decompress object is better for in-memory decompression, the _ZlibDecompressor is hidden. It only makes sense in file decompression, and that is already implemented now in the gzip library. No need to bother the users with this. + The ZlibDecompressor uses the older Cpython arrange_output_buffer functions, as those are faster and more appropriate for the use case. + GzipFile.read has been optimized. There is no longer a `unconsumed_tail` member to write back to padded file. This is instead handled by the ZlibDecompressor itself, which has an internal buffer. `_add_read_data` has been inlined, as it was just two calls. EDIT: While I am adding improvements anyway, I figured I could add another one-liner optimization now to the python -m gzip application. That read chunks in io.DEFAULT_BUFFER_SIZE previously, but has been updated now to use READ_BUFFER_SIZE chunks.
* gh-90928: Improve static initialization of keywords tuple in AC (#95907)Erlend E. Aasland2022-08-131-221/+61

* gh-90928: Statically Initialize the Keywords Tuple in Clinic-Generated Code ↵Eric Snow2022-08-111-11/+347
| | | | | | | | | | | | | | | | (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 Stinner2022-05-031-17/+17
| | | | Replace "(PyCFunction)(void(*)(void))func" cast with _PyCFunction_CAST(func).
* gh-91583: AC: Fix regression for functions with defining_class (GH-91739)Serhiy Storchaka2022-04-301-63/+98
| | | | | Argument Clinic now generates the same efficient code as before adding the defining_class parameter.
* bpo-38256: Fix binascii.crc32() when inputs are 4+GiB (GH-32000)Gregory P. Smith2022-03-201-3/+8
| | | | | | | When compiled with `USE_ZLIB_CRC32` defined (`configure` sets this on POSIX systems), `binascii.crc32(...)` failed to compute the correct value when the input data was >= 4GiB. Because the zlib crc32 API is limited to a 32-bit length. This lines it up with the `zlib.crc32(...)` implementation that doesn't have that flaw. **Performance:** This also adopts the same GIL releasing for larger inputs logic that `zlib.crc32` has, and causes the Windows build to always use zlib's crc32 instead of our slow C code as zlib is a required build dependency on Windows.

* bpo-1635741 port zlib module to multi-phase init (GH-21995)Mohamed Koubaa2020-09-071-95/+141
| | | Port the zlib extension module to multi-phase initialization (PEP 489).
* bpo-40792: Make the result of PyNumber_Index() always having exact type int. ↵Serhiy Storchaka2020-05-281-4/+4
| | | | | | | | | | | | (GH-20443) Previously, the result could have been an instance of a subclass of int. Also revert bpo-26202 and make attributes start, stop and step of the range object having exact type int. Add private function _PyNumber_Index() which preserves the old behavior of PyNumber_Index() for performance to use it in the conversion functions like PyLong_AsLong().
* bpo-37999: No longer use __int__ in implicit integer conversions. (GH-15636)Serhiy Storchaka2020-05-261-62/+34

* bpo-31926: fix missing *_METHODDEF statements by argument clinic (#4230)Tal Einat2017-11-031-1/+5
| | | | | | | | | When a single .c file contains several functions and/or methods with the same name, a safety _METHODDEF #define statement is generated only for one of them. This fixes the bug by using the full name of the function to avoid duplicates rather than just the name.

| | | | | | | | The function '_PyArg_ParseStack()' and '_PyArg_UnpackStack' were failing (with error "XXX() takes Y argument (Z given)") before the function '_PyArg_NoStackKeywords()' was called. Thus, the latter did not raise its more meaningful error : "XXX() takes no keyword arguments".

* Issue #25626: Change zlib to accept Py_ssize_t and cap to UINT_MAXMartin Panter2015-11-201-4/+4
| | | | | | | | | | | | | | The underlying zlib library stores sizes in “unsigned int”. The corresponding Python parameters are all sizes of buffers filled in by zlib, so it is okay to reduce higher values to the UINT_MAX internal cap. OverflowError is still raised for sizes that do not fit in Py_ssize_t. Sizes are now limited to Py_ssize_t rather than unsigned long, because Python byte strings cannot be larger than Py_ssize_t. Previously this could result in a SystemError on 32-bit platforms. This resolves a regression in the gzip module when reading more than UINT_MAX or LONG_MAX bytes in one call, introduced by revision 62723172412c.
