In Python 3.8 and prior, `pathlib.Path.__exit__()` marked a path as closed;
some subsequent attempts to perform I/O would raise an IOError. This
functionality was never documented, and had the effect of making `Path`
objects mutable, contrary to PEP 428. In Python 3.9 we made `__exit__()` a
no-op, and in 3.11 `__enter__()` began raising deprecation warnings. Here
we remove both methods.
This matches the GIL releasing behavior of our existing `_hashopenssl`
module, extending it to the HACL* built-ins.
Includes adding comments to better describe the ENTER/LEAVE macros
purpose and explain the lock strategy in both existing and new code.
Apply BOLT optimizations to libpython for shared builds. Most of the C
code is in libpython so it is critical to apply BOLT there fully realize
BOLT benefits.
This change also reworks how BOLT instrumentation is applied. It
effectively removes the readelf based logic added in gh-101525 and
replaces it with a mechanism that saves a copy of the pre-bolt binary
and restores that copy when necessary. This allows us to perform BOLT
optimizations without having to manually delete the output binary to
force a new bolt run.
Also:
- add a clean-bolt target for purging BOLT files and hook that up to the
clean target
- .gitignore BOLT related files
Before and after this refactor, `make` will no-op after a previous run.
Both versions should also share common make DAG deficiencies where
targets fail to trigger as often as they need to or can trigger
prematurely in certain scenarios. e.g. after this change you may need to
`rm profile-bolt-stamp` to force a BOLT run because there aren't
appropriate non-phony targets for BOLT's make target to depend on.
To make it easier to iterate on custom BOLT settings, the flags to pass
to instrumentation and application are now defined in configure and can
be overridden by passing BOLT_INSTRUMENT_FLAGS and BOLT_APPLY_FLAGS.
Fix a race condition in the internal `multiprocessing.process` cleanup
logic that could manifest as an unintended `AttributeError` when calling
`BaseProcess.close()`.

* Support for conversion specifiers o (octal) and X (uppercase hexadecimal).
* Support for length modifiers j (intmax_t) and t (ptrdiff_t).
* Length modifiers are now applied to all integer conversions.
* Support for wchar_t C strings (%ls and %lV).
* Support for variable width and precision (*).
* Support for flag - (left alignment).
This commit replaces the Python implementation of the tokenize module with an implementation
that reuses the real C tokenizer via a private extension module. The tokenize module now implements
a compatibility layer that transforms tokens from the C tokenizer into Python tokenize tokens for backward
compatibility.
As the C tokenizer does not emit some tokens that the Python tokenizer provides (such as comments and non-semantic newlines), a new special mode has been added to the C tokenizer mode that currently is only used via
the extension module that exposes it to the Python layer. This new mode forces the C tokenizer to emit these new extra tokens and add the appropriate metadata that is needed to match the old Python implementation.

bpo-17258: `multiprocessing` now supports stronger HMAC algorithms for inter-process connection authentication rather than only HMAC-MD5.

gpshead: I Reworked to be more robust while keeping the idea.
The protocol modification idea remains, but we now take advantage of the
message length as an indicator of legacy vs modern protocol version. No
more regular expression usage. We now default to HMAC-SHA256, but do so
in a way that will be compatible when communicating with older clients
or older servers. No protocol transition period is needed.
More integration tests to verify these claims remain true are required. I'm
unaware of anyone depending on multiprocessing connections between
different Python versions.

This PR updates `math.nextafter` to add a new `steps` argument. The behaviour is as though `math.nextafter` had been called `steps` times in succession.

New additions to the tty library. Functions added: cfmakeraw(), and cfmakecbreak(). The
functions setcbreak() and setraw() now return original termios to save an extra tcgetattr() call.
