* gh-106320: Move private _PyHash API to the internal C API (#107026)Victor Stinner2023-07-221-0/+1
| | | | | * No longer export most private _PyHash symbols, only export the ones which are needed by shared extensions. * Modules/_xxtestfuzz/fuzzer.c now uses the internal C API.
* gh-106521: Remove _PyObject_LookupAttr() function (GH-106642)Serhiy Storchaka2023-07-121-1/+1
|
* gh-106320: Remove private _PyImport C API functions (#106383)Victor Stinner2023-07-031-0/+5
| | | | | | * Remove private _PyImport C API functions: move them to the internal C API (pycore_import.h). * No longer export most of these private functions. * _testcapi avoids private _PyImport_GetModuleAttrString().
* gh-104922: remove PY_SSIZE_T_CLEAN (#106315)Inada Naoki2023-07-021-2/+0

* gh-106023: Update code using _PyObject_FastCall() (#106257)Victor Stinner2023-06-301-14/+8
| | | Replace _PyObject_FastCall() calls with PyObject_Vectorcall().
* gh-105375: Improve error handling in _elementtree (#105591)Erlend E. Aasland2023-06-091-3/+7
| | | Fix bugs where exceptions could end up being overwritten.
* gh-92536: Remove PyUnicode_READY() calls (#105210)Victor Stinner2023-06-011-2/+0
| | | | Since Python 3.12, PyUnicode_READY() does nothing and always returns 0.
* GH-103092: isolate `_elementtree` (#104561)Kumar Aditya2023-05-161-43/+42
|
* gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)Eric Snow2023-05-051-0/+3
| | | Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).
* gh-92123: Adapt _elementtree to multi-phase init (PEP 489) (#101285)Erlend E. Aasland2023-01-241-82/+117

* GH-92123: Pass _elementtree state as parameter (#101189)Erlend E. Aasland2023-01-241-57/+73

* GH-92123: Store _elementtree state in type contexts (#101190)Erlend E. Aasland2023-01-231-17/+21
| | | | - add state pointer to TreeBuilderObject - add state pointer to XMLParserObject
* gh-83122: Deprecate testing element truth values in `ElementTree` (#31149)Jacob Walls2023-01-231-0/+18
| | | | | | | When testing element truth values, emit a DeprecationWarning in all implementations. This had emitted a FutureWarning in the rarely used python-only implementation since ~2.7 and has always been documented as a behavior not to rely on. Matching an element in a tree search but having it test False can be unexpected. Raising the warning enables making the choice to finally raise an exception for this ambiguous behavior in the future.
* GH-92123: Move _elementtree heap types to module state (#101187)Erlend E. Aasland2023-01-211-57/+91

* gh-92123: Convert `_elementtree` types to heap types (#99221)Erlend E. Aasland2023-01-201-229/+157

* gh-99845: Use size_t type in __sizeof__() methods (#99846)Victor Stinner2022-11-301-6/+7
| | | | | | | | The implementation of __sizeof__() methods using _PyObject_SIZE() now use an unsigned type (size_t) to compute the size, rather than a signed type (Py_ssize_t). Cast explicitly signed (Py_ssize_t) values to unsigned type (Py_ssize_t).
* gh-99537: Use Py_SETREF(var, NULL) in C code (#99687)Victor Stinner2022-11-231-2/+1
| | | Replace "Py_DECREF(var); var = NULL;" with "Py_SETREF(var, NULL);".
* gh-99300: Replace Py_INCREF() with Py_NewRef() in _elementtree.c (#99696)Victor Stinner2022-11-221-69/+36
| | | | | | | * Replace Py_INCREF() and Py_XINCREF() using a cast with Py_NewRef() and Py_XNewRef() in Modules/_elementtree.c. * Make reference counting more explicit: don't steal implicitly a reference on PyList_SET_ITEM(), use Py_NewRef() instead. * Replace PyModule_AddObject() with PyModule_AddObjectRef().
* gh-99537: Use Py_SETREF() function in C code (#99656)Victor Stinner2022-11-221-4/+2
| | | | | | | | | | | | | | | Fix potential race condition in code patterns: * Replace "Py_DECREF(var); var = new;" with "Py_SETREF(var, new);" * Replace "Py_XDECREF(var); var = new;" with "Py_XSETREF(var, new);" * Replace "Py_CLEAR(var); var = new;" with "Py_XSETREF(var, new);" Other changes: * Replace "old = var; var = new; Py_DECREF(var)" with "Py_SETREF(var, new);" * Replace "old = var; var = new; Py_XDECREF(var)" with "Py_XSETREF(var, new);" * And remove the "old" variable.
* gh-99300: Replace Py_INCREF() with Py_NewRef() (#99513)Victor Stinner2022-11-161-8/+4
| | | | Replace Py_INCREF() and Py_XINCREF() using a cast with Py_NewRef() and Py_XNewRef().
* gh-99300: Use Py_NewRef() in Modules/_elementtree.c (#99438)Victor Stinner2022-11-131-82/+37
| | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in Modules/_elementtree.c.
* GH-90699: Remove `_Py_IDENTIFIER` usage from `_elementtree` module (GH-99012)Kumar Aditya2022-11-021-25/+59

* gh-93741: Add private C API _PyImport_GetModuleAttrString() (GH-93742)Serhiy Storchaka2022-06-141-6/+2
| | | | | | It combines PyImport_ImportModule() and PyObject_GetAttrString() and saves 4-6 lines of code on every use. Add also _PyImport_GetModuleAttr() which takes Python strings as arguments.
* gh-89653: Use int type for Unicode kind (#92704)Victor Stinner2022-05-131-1/+1
| | | | Use the same type that PyUnicode_FromKindAndData() kind parameter type (public C API): int.
* gh-91320: Use _PyCFunction_CAST() (#92251)Victor Stinner2022-05-031-1/+1
| | | | | | | | | | Replace "(PyCFunction)(void(*)(void))func" cast with _PyCFunction_CAST(func). Change generated by the command: sed -i -e \ 's!(PyCFunction)(void(\*)(void)) *\([A-Za-z0-9_]\+\)!_PyCFunction_CAST(\1)!g' \ $(find -name "*.c")

* bpo-45948: Remove constructor discrepancy in C version of ↵Jacob Walls2022-02-121-3/+3
| | | | | ElementTree.XMLParser (GH-31152) Both implementations accept target=None now.
* 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-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.

* bpo-38392: PyObject_GC_Track() validates object in debug mode (GH-16615)Victor Stinner2019-10-071-2/+2
| | | | | | | | In debug mode, PyObject_GC_Track() now calls tp_traverse() of the object type to ensure that the object is valid: test that objects visited by tp_traverse() are valid. Fix pyexpat.c: only track the parser in the GC once the parser is fully initialized.
* bpo-37206: Unrepresentable default values no longer represented as None. ↵Serhiy Storchaka2019-09-141-9/+9
| | | | | | | (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.
