| | | | | | | :warning: :warning: Note for reviewers, hackers and fellow systems/low-level/compiler engineers :warning: :warning: If you have a lot of experience with this kind of shenanigans and want to improve the **first** version, **please make a PR against my branch** or **reach out by email** or **suggest code changes directly on GitHub**. If you have any **refinements or optimizations** please, wait until the first version is merged before starting hacking or proposing those so we can keep this PR productive.

* gh-95781: More strict format string checking in PyUnicode_FromFormatV() ↵Serhiy Storchaka2022-08-081-3/+5
| | | | | | | | | (GH-95784) An unrecognized format character in PyUnicode_FromFormat() and PyUnicode_FromFormatV() now sets a SystemError. In previous versions it caused all the rest of the format string to be copied as-is to the result string, and any extra arguments discarded.

* gh-87961: Remove outdated notes from functions that aren't in the Limited ↵Petr Viktorin2022-06-083-26/+0
| | | | | | | | | | | | API (GH-93581) * Remove outdated notes from functions that aren't in the Limited API Nowadays everything that *is* in the Limited API has a note added automatically. These notes could mislead people to think that these functions could never be added to the limited API. Remove them. * Also remove forgotten note on tp_vectorcall_offset not being finalized
* gh-60074: add new stable API function PyType_FromMetaclass (GH-93012)Wenzel Jakob2022-05-272-5/+17
| | | | | | | | Added a new stable API function ``PyType_FromMetaclass``, which mirrors the behavior of ``PyType_FromModuleAndSpec`` except that it takes an additional metaclass argument. This is, e.g., useful for language binding tools that need to store additional information in the type object.
* gh-93202: Always use %zd printf formatter (#93201)Victor Stinner2022-05-252-7/+0
| | | | | | | | | | | | | | | | Python now always use the ``%zu`` and ``%zd`` printf formats to format a size_t or Py_ssize_t number. Building Python 3.12 requires a C11 compiler, so these printf formats are now always supported. * PyObject_Print() and _PyObject_Dump() now use the printf %zd format to display an object reference count. * Update PY_FORMAT_SIZE_T comment. * Remove outdated notes about the %zd format in PyBytes_FromFormat() and PyUnicode_FromFormat() documentations. * configure no longer checks for the %zd format and no longer defines PY_FORMAT_SIZE_T macro in pyconfig.h. * pymacconfig.h no longer undefines PY_FORMAT_SIZE_T: macOS 10.4 is no longer supported. Python 3.12 now requires macOS 10.6 (Snow Leopard) or newer.
* gh-93103: Enhance PyConfig.parser_debug documentation (#93186)Victor Stinner2022-05-241-0/+3
| | | | Document that -d option and PYTHONDEBUG env var require a debug build of Python. Also mention them in the debug build documentation.

| | | | | | | Update documentation of PyUnicode_DecodeFSDefault(), PyUnicode_DecodeFSDefaultAndSize() and PyUnicode_EncodeFSDefault(): they now use the filesystem encoding and error handler of PyConfig, Py_FileSystemDefaultEncoding and Py_FileSystemDefaultEncodeErrors variables are no longer used.
* gh-93103: Deprecate global configuration variable (#93104)Victor Stinner2022-05-232-7/+119
| | | | | Deprecate global configuration variables, like Py_IgnoreEnvironmentFlag, in the documentation: the Py_InitializeFromConfig() API should be instead.

| | | | | | | | | | Use _Py_CAST() and _Py_STATIC_CAST() in macros wrapping static inline functions of unicodeobject.h. Change also the kind type from unsigned int to int: same parameter type than PyUnicode_FromKindAndData(). The limited API version 3.11 no longer casts arguments to expected types.
