This fixes a crash when running the PyO3 test suite on the free-threaded
build. The `qsbr` field is initialized after the `PyThreadState` is
added to the interpreter's linked list -- it might still be NULL.
Instead, we "steal" the queue of to-be-freed memory blocks. This is
always initialized (possibly empty) and protected by the stop the world
pause.
We previously used `AC_RUN_IF_ELSE` with a short test program to detect
if `-latomic` is needed, but that requires choosing a specific default
value when cross-compiling because the test program is not run.
Some cross compilation targets like `wasm32-emscripten` do not support
`-latomic`, while other cross compilation targets, like
`arm-linux-gnueabi` require it.
It is an alternate constructor which only accepts a single numeric argument.
Unlike to Decimal.from_float() it accepts also Decimal.
Unlike to the standard constructor, it does not accept strings and tuples.
It is an alternative constructor which only accepts a single numeric argument.
Unlike to Fraction.from_float() and Fraction.from_decimal() it accepts any
real numbers supported by the standard constructor (int, float, Decimal,
Rational numbers, objects with as_integer_ratio()).
Unlike to the standard constructor, it does not accept strings.
Lock `ZoneInfoType` to protect accesses to `ZONEINFO_STRONG_CACHE`.
Refactor the `tp_new` handler to use Argument Clinic so that we can just
use `@critical_section` annotations on the relevant functions.
Also use `PyDict_SetDefaultRef` instead of `PyDict_SetDefault` when
inserting into the `TIMEDELTA_CACHE`.
`PurePath.__init__()` incorrectly uses the `_raw_paths` of a given
`PurePath` object with a different flavour, even though the procedure to
join path segments can differ between flavours.
This change makes the `_raw_paths`-enabled deferred joining apply _only_
when the path flavours match.

In some locales (like French or Hebrew) the full or abbreviated names of
the default month and weekday used in __calc_date_time can be part of
other name or constant part of the %c format. The month name can also
match %m with constant suffix (like in Japanese). So the code failed to
correctly distinguish formats %a, %A, %b, %B and %m.
Cycle all month and all days of the week to find the variable part
and distinguish %a from %A and %b from %B or %m.
Fixed locales for the following languges:
Arabic, Bislama, Breton, Bodo, Kashubian, Chuvash, Estonian, French, Irish,
Ge'ez, Gurajati, Manx Gaelic, Hebrew, Hindi, Chhattisgarhi, Haitian Kreyol,
Japanese, Kannada, Korean, Marathi, Malay, Norwegian, Nynorsk, Punjabi,
Rajasthani, Tok Pisin, Yoruba, Yue Chinese, Yau/Nungon and Chinese.

This follows GNU gzip, which defaults to using 0 as the mtime
for compressing stdin, where no file mtime is involved.
This makes the output of gzip.compress() deterministic by default,
greatly helping reproducible builds.

Raise ValueError in add_argument() if either explicit nargs=0 or action
that does not consume arguments (like 'store_const' or 'store_true') is
specified for positional argument.
Previously, all nested mutually exclusive groups lost their connection
to the group containing them and were displayed as belonging directly
to the parser.

memcopy'ing arbitrary values to _Bool variable triggers undefined
behaviour. Avoid this.
We assume that `false` is represented by all zero bytes.

* Add definitions for "context", "current context", and "context
management protocol".
* Update related definitions to be consistent with the new
definitions.
* Restructure the documentation for the `contextvars.Context` class
to prepare for adding context manager support, and for consistency
with the definitions.
* Use `testcode` and `testoutput` to test the `Context.run` example.
* Expand the documentation for the `Py_CONTEXT_EVENT_ENTER` and
`Py_CONTEXT_EVENT_EXIT` events to clarify and to prepare for
planned changes.
As argparse now detects by default when the code was run as a module.
This leads to using the actual executable name instead of simply "python"
to display in the usage message ("usage: python -m ...").
Fix a crash caused by immortal interned strings being shared between
sub-interpreters that use basic single-phase init. In that case, the string
can be used by an interpreter that outlives the interpreter that created and
interned it. For interpreters that share obmalloc state, also share the
interned dict with the main interpreter.
This is an un-revert of gh-124646 that then addresses the Py_TRACE_REFS
failures identified by gh-124785.

This allows testing Y2038 with system time set to after that,
so that actual Y2038 issues can be exposed, and not masked
by expired certificate errors.

If the PYTHON_BASIC_REPL environment variable is set, the site module
no longer imports the _pyrepl module.
Moreover, the site module now respects -E and -I command line
options: ignore PYTHON_BASIC_REPL in this case.
- move the Py_Main documentation from the very high level API section
to the initialization and finalization section
- make it clear that it encapsulates a full Py_Initialize/Finalize
cycle of its own
- point out that exactly which settings will be read and applied
correctly when Py_Main is called after a separate runtime
initialization call is version dependent
- be explicit that Py_IsInitialized can be called prior to
initialization
- actually test that Py_IsInitialized can be called prior to
initialization
- flush stdout in the embedding tests that run code so it appears
in the expected order when running with "-vv"
- make "-vv" on the subinterpreter embedding tests less spammy

The function now sets temporarily the LC_CTYPE locale to the locale
of the category that determines the requested value if the locales are
different and the resulting string is non-ASCII.
This temporary change affects other threads.
