* Make Py_{SIZE,IS_TYPE,SET_SIZE} regular functions in stable ABI
Group them together with Py_TYPE & Py_SET_TYPE to cut down
on repetitive preprocessor macros.
Format repetitive definitions in object.c more concisely.
Py_SET_TYPE is still left out of the Limited API.
* test_hashlib: better handle support for SHA3
It's possible that the SSL library supports only SHA3 algo and doesn't
have SHAKE one.
The current test wrongly detect this and set both HASH and HASHXOF to
None expecting to have the extra SHA3 attributes present but this should
only be true for SHAKE algo.
To better handle this, move the HASH condition to a dedicated try-expect
condition and check if HASHXOF is None in the relevant code effectively
checking if SHA3 is supported by the SSL library but SHAKE algo needs to
use the sha3module one.

Most of the `self.assertTrue(self.called)` checks are flaky because
the worker threads may sometimes finish before the main thread calls
`self.during_threads()`.
Simplify preload regression test using `__main__`
With the fix for gh-126631 `__main__` modules can be preloaded and the regression
test for gh-135335 can be simplified to just use a self-contained script rather
than requiring a module.
Note this assumes and implicitly tests that `__main__` is preloaded by default.
If we overflowed the global version counter (i.e., after 2*24 calls to
`_PyMonitoring_SetEvents`), we bailed out after setting global monitoring
events but before instrumenting code objects, which led to assertion errors
later on.
Also add a `time.sleep()` to `test_free_threading.test_monitoring` to avoid
overflowing the global version counter.
Revert (unneeded, already done elsewhere) "gh-98552: flush std streams in the multiprocessing forkserver before fork (#141849)"
This reverts commit 58badb1711.
Added a critical section to protect the states of `ReaderObj` and `WriterObj` in the free-threading build. Without the critical sections, both new free-threading tests were crashing.
* gh-138697: Fix inferring dest from a single-dash long option in argparse
If a short option and a single-dash long option are passed to add_argument(),
dest is now inferred from the single-dash long option.
* Make double-dash options taking priority over single-dash long options.

This commit updates CI and configuration from wasi-sdk-25 to wasi-sdk-29
which was released recently. This notably includes stubs for pthreads
which all return errors, so some adjustment in logic is necessary to
retain knowledge that WASI cannot yet spawn threads for example.
This additionally increases the wasm stack allowance to 32MiB from 16MiB
to accomodate the `test_recursive_pickle` test in the
`test_functools.py` file. It looks like the Clang/LLVM update that
happened in wasi-sdk-29 relative to wasi-sdk-25 is likely the cause of
this where presumably functions have more locals than before and/or a
slightly adjusted stack space requirement which overflows the stack.
In Fedora, we've been given a slightly incomplete reproducer for a problematic
Python 3.14 color-related change in argparse that leads to an exception when
Python is used from mod_wsgi: https://bugzilla.redhat.com/2414940
mod_wsgi replaces sys.stdout with a custom object that raises OSError on .fileno():
8460dbfcd5/src/server/wsgi_logger.c (L434-L440)
This should be supported, as the documentation of fileno explicitly says:
> An OSError is raised if the IO object does not use a file descriptor.
https://docs.python.org/3.14/library/io.html#io.IOBase.fileno
The previously expected exception inherits from OSError,
so it is still expected.
Fixes https://github.com/python/cpython/issues/141570
