* fixes gh-109559: Update `unicodedata` for Unicode 15.1.0 (GH-109560)James Gerity2023-09-201-950/+1013
| | | | | --------- Co-authored-by: Benjamin Peterson <benjamin@python.org>
* gh-108511: Add C API functions which do not silently ignore errors (GH-109025)Serhiy Storchaka2023-09-176-69/+73
| | | | | | | | | Add the following functions: * PyObject_HasAttrWithError() * PyObject_HasAttrStringWithError() * PyMapping_HasKeyWithError() * PyMapping_HasKeyStringWithError()
* gh-106213: Make Emscripten trampolines work with JSPI (GH-106219)Hood Chatham2023-09-152-26/+1
| | | | | | | | | | | | | | | | | | | | | | | | There is a WIP proposal to enable webassembly stack switching which have been implemented in v8: https://github.com/WebAssembly/js-promise-integration It is not possible to switch stacks that contain JS frames so the Emscripten JS trampolines that allow calling functions with the wrong number of arguments don't work in this case. However, the js-promise-integration proposal requires the [type reflection for Wasm/JS API](https://github.com/WebAssembly/js-types) proposal, which allows us to actually count the number of arguments a function expects. For better compatibility with stack switching, this PR checks if type reflection is available, and if so we use a switch block to decide the appropriate signature. If type reflection is unavailable, we should use the current EMJS trampoline. We cache the function argument counts since when I didn't cache them performance was negatively affected.

* gh-107265: Remove all ENTER_EXECUTOR when execute _Py_Instrument (gh-108539)Dong-hee Na2023-09-071-0/+17
|
* gh-108751: Add copy.replace() function (GH-108752)Serhiy Storchaka2023-09-061-0/+1
| | | | | | | | | It creates a modified copy of an object by calling the object's __replace__() method. It is a generalization of dataclasses.replace(), named tuple's _replace() method and replace() methods in various classes, and supports all these stdlib classes.
* gh-106307: Fix PyMapping_GetOptionalItemString() (GH-108797)Serhiy Storchaka2023-09-061-0/+2
| | | | | | The resulting pointer was not set to NULL if the creation of a temporary string object was failed. The tests were also missed due to oversight.
* gh-108991: replace _PyFrame_GetState by two simpler functions (#108992)Irit Katriel2023-09-061-31/+20

* gh-108765: Python.h no longer includes <ctype.h> (#108831)Victor Stinner2023-09-034-10/+4
| | | | | | | | | | | | | | | | | | | | | | | Remove <ctype.h> in C files which don't use it; only sre.c and _decimal.c still use it. Remove _PY_PORT_CTYPE_UTF8_ISSUE code from pyport.h: * Code added by commit b5047fd01948ab108edcc1b3c2c901d915814cfd in 2004 for MacOSX and FreeBSD. * Test removed by commit 52ddaefb6bab1a74ecffe8519c02735794ebfbe1 in 2007, since Python str type now uses locale independent functions like Py_ISALPHA() and Py_TOLOWER() and the Unicode database. Modules/_sre/sre.c replaces _PY_PORT_CTYPE_UTF8_ISSUE with new functions: sre_isalnum(), sre_tolower(), sre_toupper(). Remove unused includes: * _localemodule.c: remove <stdio.h>. * getargs.c: remove <float.h>. * dynload_win.c: remove <direct.h>, it no longer calls _getcwd() since commit fb1f68ed7cc1536482d1debd70a53c5442135fe2 (in 2001).
* gh-108767: Replace ctype.h functions with pyctype.h functions (#108772)Victor Stinner2023-09-011-4/+4
| | | | | | | | | | | | | | Replace <ctype.h> locale dependent functions with Python "pyctype.h" locale independent functions: * Replace isalpha() with Py_ISALPHA(). * Replace isdigit() with Py_ISDIGIT(). * Replace isxdigit() with Py_ISXDIGIT(). * Replace tolower() with Py_TOLOWER(). Leave Modules/_sre/sre.c unchanged, it uses locale dependent functions on purpose. Include explicitly <ctype.h> in _decimal.c to get isascii().
* gh-108634: PyInterpreterState_New() no longer calls Py_FatalError() (#108748)Victor Stinner2023-09-011-2/+3
| | | | | | | | | | | | pycore_create_interpreter() now returns a status, rather than calling Py_FatalError(). * PyInterpreterState_New() now calls Py_ExitStatusException() instead of calling Py_FatalError() directly. * Replace Py_FatalError() with PyStatus in init_interpreter() and _PyObject_InitState(). * _PyErr_SetFromPyStatus() now raises RuntimeError, instead of ValueError. It can now call PyErr_NoMemory(), raise MemoryError, if it detects _PyStatus_NO_MEMORY() error message.
* gh-107603: Argument Clinic: Only include pycore_gc.h if needed (#108726)Victor Stinner2023-08-3121-105/+59
| | | | | | | | | | | | | | | | | | | | 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-108634: Py_TRACE_REFS uses a hash table (#108663)Victor Stinner2023-08-315-106/+177
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Python built with "configure --with-trace-refs" (tracing references) is now ABI compatible with Python release build and debug build. Moreover, it now also supports the Limited API. Change Py_TRACE_REFS build: * Remove _PyObject_EXTRA_INIT macro. * The PyObject structure no longer has two extra members (_ob_prev and _ob_next). * Use a hash table (_Py_hashtable_t) to trace references (all objects): PyInterpreterState.object_state.refchain. * Py_TRACE_REFS build is now ABI compatible with release build and debug build. * Limited C API extensions can now be built with Py_TRACE_REFS: xxlimited, xxlimited_35, _testclinic_limited. * No longer rename PyModule_Create2() and PyModule_FromDefAndSpec2() functions to PyModule_Create2TraceRefs() and PyModule_FromDefAndSpec2TraceRefs(). * _Py_PrintReferenceAddresses() is now called before finalize_interp_delete() which deletes the refchain hash table. * test_tracemalloc find_trace() now also filters by size to ignore the memory allocated by _PyRefchain_Trace(). Test changes for Py_TRACE_REFS: * Add test.support.Py_TRACE_REFS constant. * Add test_sys.test_getobjects() to test sys.getobjects() function. * test_exceptions skips test_recursion_normalizing_with_no_memory() and test_memory_error_in_PyErr_PrintEx() if Python is built with Py_TRACE_REFS. * test_repl skips test_no_memory(). * test_capi skisp test_set_nomemory().
* gh-106320: Remove private _PyErr_ChainExceptions() (#108713)Victor Stinner2023-08-312-2/+4
| | | | | | | | | | | | | Remove _PyErr_ChainExceptions(), _PyErr_ChainExceptions1() and _PyErr_SetFromPyStatus() functions from the public C API. * Move the private _PyErr_ChainExceptions() and _PyErr_ChainExceptions1() function to the internal C API (pycore_pyerrors.h). * Move the private _PyErr_SetFromPyStatus() to the internal C API (pycore_initconfig.h). * No longer export the _PyErr_ChainExceptions() function. * Move run_in_subinterp_with_config() from _testcapi to _testinternalcapi.
* gh-108635: Make parameters of some implementations of special methods ↵Serhiy Storchaka2023-08-292-215/+28
| | | | positional-only (GH-108636)
* gh-106320: Remove private _PyErr_SetKeyError() (#108607)Victor Stinner2023-08-291-0/+1
| | | | Move the private _PyErr_SetKeyError() function to the internal C API (pycore_pyerrors.h).
* gh-106320: Remove _PyAnextAwaitable_Type from the public C API (#108597)Victor Stinner2023-08-291-3/+4
| | | | It's not needed to declare it in Include/iterobject.h: just use "extern" where it's used (only in object.c).
* gh-108240: Add pycore_capsule.h internal header file (#108596)Victor Stinner2023-08-291-0/+1
| | | | Move _PyCapsule_SetTraverse() definition to a new internal header file: pycore_capsule.h.
* gh-108295: Fix crashes with TypeVar weakrefs (#108517)Jelle Zijlstra2023-08-271-0/+3

* gh-107913: Fix possible losses of OSError error codes (GH-107930)Serhiy Storchaka2023-08-261-1/+1
| | | | | | Functions like PyErr_SetFromErrno() and SetFromWindowsErr() should be called immediately after using the C API which sets errno or the Windows error code.
* gh-106320: Remove private AC converter functions (#108505)Victor Stinner2023-08-267-6/+13
| | | | | | | | | | | | | | 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: Replace _PyLong_AsInt() with PyLong_AsInt() (#108459)Victor Stinner2023-08-243-4/+4
| | | | | | Change generated by the command: sed -i -e 's!_PyLong_AsInt!PyLong_AsInt!g' \ $(find -name "*.c" -o -name "*.h")
* gh-108444: Argument Clinic uses PyLong_AsInt() (#108458)Victor Stinner2023-08-247-30/+30
| | | | Argument Clinic now uses the new public PyLong_AsInt(), rather than the old name _PyLong_AsInt().
* gh-108444: Add PyLong_AsInt() public function (#108445)Victor Stinner2023-08-241-1/+1
| | | | | | * Rename _PyLong_AsInt() to PyLong_AsInt(). * Add documentation. * Add test. * For now, keep _PyLong_AsInt() as an alias to PyLong_AsInt().
* gh-106320: Remove private _PyEval function (#108433)Victor Stinner2023-08-2412-2/+15
| | | | | | | | | | | | | | Move private _PyEval functions to the internal C API (pycore_ceval.h): * _PyEval_GetBuiltin() * _PyEval_GetBuiltinId() * _PyEval_GetSwitchInterval() * _PyEval_MakePendingCalls() * _PyEval_SetProfile() * _PyEval_SetSwitchInterval() * _PyEval_SetTrace() No longer export most of these functions.
* gh-106320: Remove private _PyManagedBuffer_Type (#108431)Victor Stinner2023-08-242-1/+4
| | | | Remove private _PyManagedBuffer_Type variable. Move it to the internal C API and no longer export it.
* gh-108308: Remove _PyDict_GetItemStringWithError() function (#108426)Victor Stinner2023-08-241-13/+0
| | | | | | | | Remove the internal _PyDict_GetItemStringWithError() function. It can now be replaced with the new public PyDict_ContainsString() and PyDict_GetItemStringRef() functions. getargs.c now now uses a strong reference for current_arg. find_keyword() returns a strong reference.
* gh-108240: _PyCapsule_SetTraverse() rejects NULL callbacks (#108417)Victor Stinner2023-08-241-15/+22

* gh-108240: Add _PyCapsule_SetTraverse() internal function (#108339)Victor Stinner2023-08-231-66/+100
| | | | | The _socket extension uses _PyCapsule_SetTraverse() to visit and clear the socket type in the garbage collector. So the _socket.socket type can be cleared in some corner cases when it wasn't possible before.
* gh-108308: Use PyDict_GetItemRef() in moduleobject.c (#108381)Victor Stinner2023-08-231-28/+40
| | | | | | | | Replace PyDict_GetItemWithError() with PyDict_GetItemRef() which returns a strong reference. Cleanup also the function: move variable definition to their first assignation, rename variable names to use name longer than 1 character.
* gh-108308: Replace _PyDict_GetItemStringWithError() (#108372)Victor Stinner2023-08-231-15/+10
| | | | | | | Replace _PyDict_GetItemStringWithError() calls with PyDict_GetItemStringRef() which returns a strong reference to the item. Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

* gh-106320: Remove _PyDict_GetItemStringWithError() function (#108313)Victor Stinner2023-08-221-0/+1
| | | | | | | | | Remove private _PyDict_GetItemStringWithError() function of the public C API: the new PyDict_GetItemStringRef() can be used instead. * Move private _PyDict_GetItemStringWithError() to the internal C API. * _testcapi get_code_extra_index() uses PyDict_GetItemStringRef(). Avoid using private functions in _testcapi which tests the public C API.
* gh-108253: Fix bug in func version cache (#108296)Guido van Rossum2023-08-221-22/+22
| | | | When a function object changed its version, a stale pointer might remain in the cache. Zap these whenever `func_version` changes (even when set to 0).

* gh-106581: Project through calls (#108067)Guido van Rossum2023-08-172-2/+80
| | | | This finishes the work begun in gh-107760. When, while projecting a superblock, we encounter a call to a short, simple function, the superblock will now enter the function using `_PUSH_FRAME`, continue through it, and leave it using `_POP_FRAME`, and then continue through the original code. Multiple frame pushes and pops are even possible. It is also possible to stop appending to the superblock in the middle of a called function, when running out of space or encountering an unsupported bytecode.
