Add special cases for classmethod and staticmethod descriptors in
_PyObject_GetMethodStackRef() to avoid calling tp_descr_get, which
avoids reference count contention on the bound method and underlying
callable. This improves scaling when calling classmethods and
staticmethods from multiple threads.
Also refactor method_vectorcall in classobject.c into a new
_PyObject_VectorcallPrepend() helper so that it can be used by
PyObject_VectorcallMethod as well.

* Add the c_init_default attribute which is used to initialize the C variable
if the default is not explicitly provided.
* Add the c_default_init() method which is used to derive c_default from
default if c_default is not explicitly provided.
* Explicit c_default and py_default are now almost always have precedence
over the generated value.
* Add support for bytes literals as default values.
* Improve support for str literals as default values (support non-ASCII
and non-printable characters and special characters like backslash or quotes).
* Fix support for str and bytes literals containing trigraphs, "/*" and "*/".
* Improve support for default values in converters "char" and "int(accept={str})".
* Converter "int(accept={str})" now requires 1-character string instead of
integer as default value.
* Add support for non-None default values in converter "Py_buffer": NULL,
str and bytes literals.
* Improve error handling for invalid default values.
* Rename Null to NullType for consistency.

Modifies the Emscripten build script to allow for custom cross-build directory
names, and to only clean Emscripten-specific paths (optionally including the
build python).

Adds an `--emsdk-cache` argument to the Emscripten build script and an
emscripten_version.txt file. If the `--emsdk-cache` argument is passed, the build script
will look in `emscripten_version.txt` to get the expected emsdk version is installed in
a folder called e.g., 4.0.12 in the directory indicated by the `--emsdk-cache` argument,
and run the build with that Emscripten tooling activated.

[3.14] gh-144551: Update CI to use latest OpenSSL versions
Also update _ssl_data_35.h to include an added symbol from 3.5.5.
(cherry picked from commit b933ef9261)
The behaviour of Cut in nested parentheses, Repeat, Opt, and similar
is somewhat chaotic. Apparently even the academic papers on PEG aren't
as clear as they could be.
And it doesn't really matter. Python only uses top-level cuts.
When that changes, we can clarify as much as necessary (and even
change the implementation to make sense for what we'll need).
Document that this is deliberately unspecified, and add a test to
make sure any decision is deliberate, tested and documented.

- Gather all documented names into a set in a single pass.
This makes the check much faster.
- Do not match substrings (e.g. documenting `PyErr_WarnEx`
doesn't mean that `PyErr_Warn` is documented)
- Consider `PY`-prefixed names (a lot of old macros use this)
(cherry picked from commit 234a15dc4e)
In optimized and `-Og` builds, arguments and local variables are frequently
unavailable in gdb. This makes `py-bt` fail to print anything useful. Use the
`PyThreadState*` pointers `_Py_tss_gilstate` and `Py_tss_tstate` to find the
interpreter frame if we can't get the frame from the
`_PyEval_EvalFrameDefault` call.

Introduce `build-python` and `build-host` subcommands for `Tools/wasm/wasi` (GH-142266)

Being more flexible in when not to explicitly set the sysroot when compiling for WASI (GH-142242)
(cherry picked from commit c5252045d3)
Co-authored-by: Brett Cannon <brett@python.org>
The dataclasses `__init__` function is generated dynamically by a call to `exec()` and so doesn't have deferred reference counting enabled. Enable deferred reference counting on functions when assigned as an attribute to type objects to avoid reference count contention when creating dataclass instances.
