Fix a race condition in "make regen-all". The deepfreeze.c source and
files generated by Argument Clinic are now generated or updated
before generating "global objects". Previously, some identifiers may
miss depending on the order in which these files were generated.
* "make regen-global-objects": Make sure that deepfreeze.c is
generated and up to date, and always run "make clinic".
* "make clinic" no longer runs generate_global_objects.py script.
* "make regen-deepfreeze" now only updates deepfreeze.c (C file).
It doesn't build deepfreeze.o (object) anymore.
* Remove misleading messages in "make regen-global-objects" and
"make clinic". They are now outdated, these commands are now
safe to use.
* Document generates files in Doc/using/configure.rst.

Statistics gathering is now off by default. Use the "-X pystats"
command line option or set the new PYTHONSTATS environment variable
to 1 to turn statistics gathering on at Python startup.
Statistics are no longer dumped at exit if statistics gathering was
off or statistics have been cleared.
Changes:
* Add PYTHONSTATS environment variable.
* sys._stats_dump() now returns False if statistics are not dumped
because they are all equal to zero.
* Add PyConfig._pystats member.
* Add tests on sys functions and on setting PyConfig._pystats to 1.
* Add Include/cpython/pystats.h and Include/internal/pycore_pystats.h
header files.
* Rename '_py_stats' variable to '_Py_stats'.
* Exclude Include/cpython/pystats.h from the Py_LIMITED_API.
* Move pystats.h include from object.h to Python.h.
* Add _Py_StatsOn() and _Py_StatsOff() functions. Remove
'_py_stats_struct' variable from the API: make it static in
specialize.c.
* Document API in Include/pystats.h and Include/cpython/pystats.h.
* Complete pystats documentation in Doc/using/configure.rst.
* Don't write "all zeros" stats: if _stats_off() and _stats_clear()
or _stats_dump() were called.
* _PyEval_Fini() now always call _Py_PrintSpecializationStats() which
does nothing if stats are all zeros.

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 b5047fd019
in 2004 for MacOSX and FreeBSD.
* Test removed by commit 52ddaefb6b
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 fb1f68ed7c (in 2001).
Python.h no longer includes <time.h>, <sys/select.h> and <sys/time.h>
standard header files.
* Add <time.h> include to xxsubtype.c.
* Add <sys/time.h> include to posixmodule.c and semaphore.c.
* readline.c includes <sys/select.h> instead of <sys/time.h>.
* resource.c no longer includes <time.h> and <sys/time.h>.
* Add 'skipped' attribute to TestResults.
* Add 'skips' attribute to DocTestRunner.
* Rename private DocTestRunner._name2ft attribute
to DocTestRunner._stats.
* Use f-string for string formatting.
* Add some tests.
* Document DocTestRunner attributes and its API for statistics.
* Document TestResults class.

* Express functions which take argument as a C string in terms of
functions which take Python object.
* Use "note" directive for PyMapping_HasKey() and
PyMapping_HasKeyString() notes.
This adds a new header that provides atomic operations on common data
types. The intention is that this will be exposed through Python.h,
although that is not the case yet. The only immediate use is in
the test file.

When overriding the `__new__` method of an enum, the underlying data type should be created directly; i.e. .
member = object.__new__(cls)
member = int.__new__(cls, value)
member = str.__new__(cls, value)
Calling `super().__new__()` finds the lookup version of `Enum.__new__`, and will now raise an exception when detected.
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().
Deprecate passing the callback callable by keyword for the following
sqlite3.Connection APIs:
- set_authorizer(authorizer_callback)
- set_progress_handler(progress_handler, ...)
- set_trace_callback(trace_callback)
The affected parameters will become positional-only in Python 3.15.
- Add param docstrings
- Link to os.SEEK_* constants
- Mention the return value in the initial paragraph

Deprecate passing name, number of arguments, and the callable as keyword
arguments, for the following sqlite3.Connection APIs:
- create_function(name, nargs, callable, ...)
- create_aggregate(name, nargs, callable)
The affected parameters will become positional-only in Python 3.15.
Fixed a sentence in dataclasses.rst
Changed "__setattr__" to "object.__setattr__" in a section that was specifically supposed to refer to the __setattr__ method of the object class. Also suppressed the link to the data model docs for __setattr__, since we're talking about a specific __setattr__ implementation, not __setattr__ methods in general.
Clearly document the supported seek() operations:
- Rewind to the start of the stream
- Restore a previous stream position (given by tell())
- Fast-forward to the end of the stream
- Mark up named tuple attributes as attributes
- Remove links for external functions
- io.BufferedIOBase has no 'buffer' attribute;
remove the link and mark up using :attr:`!buffer`
- (Re)format some tables as bullet lists:
- sys._emscripten_info
- sys.hash_info
- sys.int_info
- sys.thread_info
- In the paragraphs mentioning 'f_trace_lines' and 'f_trace_opcodes',
add links to the frame objects reference.

- Normalise capitalisation and punctuation
- Use attribute markup for named tuple attributes
- Use :c:macro: markup for C macros
- Use a list for the 'rounds' attribute values
- Use list-table, for better .rst readability
- Remove one unneeded sys.float_info.dig link

Deprecate passing optional arguments maxsplit, count and flags in
module-level functions re.split(), re.sub() and re.subn() as positional.
They should only be passed by keyword.
PEP 683 (immortal objects) revealed some ways in which the Python documentation has been unnecessarily coupled to the implementation details of reference counts. In the end users should focus on reference ownership, including taking references and releasing them, rather than on how many reference counts an object has.
This change updates the documentation to reflect that perspective. It also updates the docs relative to immortal objects in a handful of places.
It is now possible to deprecate passing parameters positionally with
Argument Clinic, using the new '* [from X.Y]' syntax.
(To be read as "keyword-only from Python version X.Y")

- Add links to `__main__` and `sys.path` where appropriate
- Ensure each paragraph never has more than one link to the same thing, to avoid visual clutter from too many links
gh-107432 Fix incorrect indentation in annotations document
Body text in https://docs.python.org/3/howto/annotations.html was
indented throughout, and was being rendered in blockquote elements.
Declare the following functions as macros, since they are actually
macros. It avoids a warning on "TYPE" or "macro" argument.
* PyMem_New()
* PyMem_Resize()
* PyModule_AddIntMacro()
* PyModule_AddStringMacro()
* PyObject_GC_New()
* PyObject_GC_NewVar()
* PyObject_New()
* PyObject_NewVar()
Add C standard C types to nitpick_ignore in Doc/conf.py:
* int64_t
* uint64_t
* uintptr_t
No longer ignore non existing "__int" type in nitpick_ignore.
Update Doc/tools/.nitignore
Update the nitpick_ignore of the documentation configuration to fix
Sphinx warnings about standard C types when declaring functions with
the "c:function" markups.
Copy standard C types declared in the "c:type" domain to the
"c:identifier" domain, since "c:function" markup looks for types in
the "c:identifier" domain.

The documentation implies that PyVectorcall_Function() was available in Python 3.8.
This is half-true - it was available under a different name. I think it's clearer to set
the "version added" to 3.9.
