* bpo-43916: Move the _PyStructSequence_InitType function to the internal API ↵Pablo Galindo2021-05-031-0/+1
| | | | (GH-25854)
* bpo-43916: Add Py_TPFLAGS_DISALLOW_INSTANTIATION type flag (GH-25721)Victor Stinner2021-04-301-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new Py_TPFLAGS_DISALLOW_INSTANTIATION type flag to disallow creating type instances: set tp_new to NULL and don't create the "__new__" key in the type dictionary. The flag is set automatically on static types if tp_base is NULL or &PyBaseObject_Type and tp_new is NULL. Use the flag on the following types: * _curses.ncurses_version type * _curses_panel.panel * _tkinter.Tcl_Obj * _tkinter.tkapp * _tkinter.tktimertoken * _xxsubinterpretersmodule.ChannelID * sys.flags type * sys.getwindowsversion() type * sys.version_info type Update MyStr example in the C API documentation to use Py_TPFLAGS_DISALLOW_INSTANTIATION. Add _PyStructSequence_InitType() function to create a structseq type with the Py_TPFLAGS_DISALLOW_INSTANTIATION flag set. type_new() calls _PyType_CheckConsistency() at exit.
* bpo-43687: Py_Initialize() creates singletons earlier (GH-25147)Victor Stinner2021-04-021-1/+2
| | | | | Reorganize pycore_interp_init() to initialize singletons before the the first PyType_Ready() call. Fix an issue when Python is configured using --without-doc-strings.
* bpo-42128: Add __match_args__ to structseq-based classes (GH-24732)Pablo Galindo2021-03-041-0/+34

* bpo-11717: fix ssize_t redefinition error when targeting 32bit Windows app ↵Jozef Grajciar2021-03-011-1/+1
| | | | (GH-24479)
* bpo-42519: Replace PyMem_MALLOC() with PyMem_Malloc() (GH-23586)Victor Stinner2020-12-011-3/+3
| | | | | | | | | | | No longer use deprecated aliases to functions: * Replace PyMem_MALLOC() with PyMem_Malloc() * Replace PyMem_REALLOC() with PyMem_Realloc() * Replace PyMem_FREE() with PyMem_Free() * Replace PyMem_Del() with PyMem_Free() * Replace PyMem_DEL() with PyMem_Free() Modify also the PyMem_DEL() macro to use directly PyMem_Free().
* bpo-42423: Accept single base class in PyType_FromModuleAndSpec() (GH-23441)Serhiy Storchaka2020-11-221-8/+1
|
* bpo-42006: Stop using PyDict_GetItem, PyDict_GetItemString and ↵Serhiy Storchaka2020-10-261-16/+59
| | | | | | | | | | | _PyDict_GetItemId. (GH-22648) These functions are considered not safe because they suppress all internal errors and can return wrong result. PyDict_GetItemString and _PyDict_GetItemId can also silence current exception in rare cases. Remove no longer used _PyDict_GetItemId. Add _PyDict_ContainsId and rename _PyDict_Contains into _PyDict_Contains_KnownHash.
* bpo-40170: Use inline _PyType_HasFeature() function (GH-22375)Victor Stinner2020-09-231-1/+1
| | | | | Use _PyType_HasFeature() in the _io module and in structseq implementation. Replace PyType_HasFeature() opaque function call with _PyType_HasFeature() inlined function.
* bpo-41078: Rename pycore_tupleobject.h to pycore_tuple.h (GH-21056)Victor Stinner2020-06-221-2/+2
|
* bpo-40217: Ensure Py_VISIT(Py_TYPE(self)) is always called for ↵Pablo Galindo2020-05-271-0/+3
| | | | | | | | | PyType_FromSpec types (reverts GH-19414) (GH-20264) Heap types now always visit the type in tp_traverse. See added docs for details. This reverts commit 0169d3003be3d072751dd14a5c84748ab63a249f. Automerge-Triggered-By: @encukou
* 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-39573: Use Py_SET_SIZE() function (GH-18402)Victor Stinner2020-02-071-1/+1
| | | | Replace direct acccess to PyVarObject.ob_size with usage of the Py_SET_SIZE() function.
* bpo-38650: Constify PyStructSequence_UnnamedField. (GH-17005)Serhiy Storchaka2019-11-161-1/+1
| | | | Make it a constant and referring to a constant string.
* bpo-37206: Unrepresentable default values no longer represented as None. ↵Serhiy Storchaka2019-09-141-2/+2
| | | | | | | (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.

| | | | | * Incref heap-allocated types in PyObject_Init * Add documentation and porting notes to What's New
* bpo-36398: Fix a possible crash in structseq_repr(). (GH-12492)Zackery Spytz2019-03-221-1/+1
| | | | | If the first PyUnicode_DecodeUTF8() call fails in structseq_repr(), _PyUnicodeWriter_Dealloc() will be called on an uninitialized _PyUnicodeWriter.
* bpo-36365: Rewrite structseq_repr() using _PyUnicodeWriter (GH-12440)Victor Stinner2019-03-191-58/+68
| | | | | No longer limit repr(structseq) to 512 bytes. Use _PyUnicodeWriter for better performance and to write directly Unicode rather than encoding repr() value to UTF-8 and then decoding from UTF-8.
* bpo-36254: Fix invalid uses of %d in format strings in C. (GH-12264)Serhiy Storchaka2019-03-131-1/+1

* Fix compiler warning in structseq_repr() (GH-10841)Victor Stinner2018-12-011-3/+3
| | | | | | | | | | | | Replace strncpy() with memcpy() in structseq_repr() to fix the following compiler warning: Objects/structseq.c:187:5: warning: 'strncpy' specified bound depends on the length of the source argument [-Wstringop-overflow=] strncpy(pbuf, typ->tp_name, len); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Objects/structseq.c:185:11: note: length computed here len = strlen(typ->tp_name) > TYPE_MAXSIZE ? TYPE_MAXSIZE : The function writes the terminating NUL byte later.
* bpo-34784: Implement correct cleanup in PyStructSequence new implementation ↵Pablo Galindo2018-11-151-0/+5
| | | | | | (GH-10536) PyTuple_Pack can fail and return NULL. If this happens, then PyType_FromSpecWithBases will incorrectly create a new type without bases. Also, it will crash on the Py_DECREF that follows. Also free members and type in error conditions.
* bpo-34784: Fix PyStructSequence_NewType with heap-allocated StructSequence ↵Eddie Elizondo2018-11-131-92/+133
| | | | (GH-9665)
* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-1/+1
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.

| | | | | | | | PyStructSequence_InitType() except that it has a return value (0 on success, -1 on error). * PyStructSequence_InitType2() now raises MemoryError on memory allocation failure * Fix also some calls to PyDict_SetItemString(): handle error

* Close #18469: Replace PyDict_GetItemString() with _PyDict_GetItemId() in ↵Victor Stinner2013-07-161-5/+20
| | | | | | | | | | | | structseq.c _PyDict_GetItemId() is more efficient: it only builds the Unicode string once. Identifiers (dictionary keys) are now created at Python initialization, and if the creation failed, Python does exit with a fatal error. Before, PyDict_GetItemString() failure was not handled: structseq_new() could call PyObject_GC_NewVar() with a negative size, and structseq_dealloc() could also crash.
