- Correctly handle `NULL` values returned by `EVP_MD_CTX_md`.
- Correctly free resources in error branches.
- Consistently suppress `_setException()` return value when needed.
- Collapse `_setException() + return NULL` into a single statement.
This adds two new methods to `multiprocessing`'s `ProcessPoolExecutor`:
- **`terminate_workers()`**: forcefully terminates worker processes using `Process.terminate()`
- **`kill_workers()`**: forcefully kills worker processes using `Process.kill()`
These methods provide users with a direct way to stop worker processes without `shutdown()` or relying on implementation details, addressing situations where immediate termination is needed.

The value taken by `FrameSummary.end_lineno` when passing `end_lineno=None` changed in gh-112097.
Previously, a `end_lineno` could be specified to be `None` directly but since 939fc6d, passing None makes
the constructor use the value of `lineno` instead.
Add support for generating UUIDv6 objects according to RFC 9562, §5.6 [1].
The functionality is provided by the `uuid.uuid6()` function which takes as inputs an optional 48-bit
hardware address and an optional 14-bit clock sequence. The UUIDv6 temporal fields are ordered
differently than those of UUIDv1, thereby providing improved database locality.

Move some `#include <stdbool.h>` after `#include "Python.h"` when `pyconfig.h` is not
included first and when we are in a platform-agnostic context. This is to avoid having
features defined by `stdbool.h` before those decided by `Python.h`.
Remove the *mode*, *parents* and *exist_ok* arguments from
`WritablePath.mkdir()`. These arguments imply support for POSIX permissions
and checking for preexistence of the path or its parents, but subclasses of
`WritablePath` may not have these capabilities.
The public `Path.mkdir()` method retains these arguments.
Remove `ReadablePath` methods duplicated by `ReadablePath.info`. To be
specific, we remove `exists()`, `is_dir()`, `is_file()` and `is_symlink()`.
The public `Path` class retains these methods.
This broke tests on the 'aarch64 Fedora Stable Clang Installed 3.x' and
'AMD64 Fedora Stable Clang Installed 3.x' build bots.
This reverts commit da4899b94a.
## Filtered recursive walk
Expanding a recursive `**` segment entails walking the entire directory
tree, and so any subsequent pattern segments (except special segments) can
be evaluated by filtering the expanded paths through a regex. For example,
`glob.glob("foo/**/*.py", recursive=True)` recursively walks `foo/` with
`os.scandir()`, and then filters paths through a regex based on "`**/*.py`,
with no further filesystem access needed.
This fixes an issue where `glob()` could return duplicate results.
## Tracking path existence
We store a flag alongside each path indicating whether the path is
guaranteed to exist. As we process the pattern:
- Certain special pattern segments (`""`, `"."` and `".."`) leave the flag
unchanged
- Literal pattern segments (e.g. `foo/bar`) set the flag to false
- Wildcard pattern segments (e.g. `*/*.py`) set the flag to true (because
children are found via `os.scandir()`)
- Recursive pattern segments (e.g. `**`) leave the flag unchanged for the
root path, and set it to true for descendants discovered via
`os.scandir()`.
If the flag is false at the end, we call `lstat()` on each path to filter
out missing paths.
## Minor speed-ups
- Exclude paths that don't match a non-terminal non-recursive wildcard
pattern _prior_ to calling `is_dir()`.
- Use a stack rather than recursion to implement recursive wildcards.
- This fixes a recursion error when globbing deep trees.
- Pre-compile regular expressions and pre-join literal pattern segments.
- Convert to/from `bytes` (a minor use-case) in `iglob()` rather than
supporting `bytes` throughout. This particularly simplifies the code
needed to handle relative bytes paths with `dir_fd`.
- Avoid calling `os.path.join()`; instead we keep paths in a normalized
form and append trailing slashes when needed.
- Avoid calling `os.path.normcase()`; instead we use case-insensitive regex
matching.
## Implementation notes
Much of this functionality is already present in pathlib's implementation
of globbing. The specific additions we make are:
1. Support for `dir_fd`
2. Support for `include_hidden`
3. Support for generating paths relative to `root_dir`
This unifies the implementations of globbing in the `glob` and `pathlib`
modules.

The race condition with `free_threadstate` and daemon threads exists in
both the free threading and default builds. We were missing a
suppression in the default build.

Remove inclusions prior to Python.h.
<stdbool.h> will cause <features.h> to be included before Python.h can
define some macros to enable some additional features, causing multiple
types not to be defined down the line.
A reference loop was resulting in the `fileobj` held by the `GzipFile`
being closed before the `GzipFile`.
The issue started with gh-89550 in 3.12, but was hidden in most cases
until 3.13 when gh-62948 made it more visible.
Add a lock to ensure that only one iOS testbed per user can start at a time, so
that the simulator discovery process doesn't collide between instances.
This moves `tstate_activate()` down to avoid a data race in the free
threading build on the `_PyRuntime`'s thread-local `autoTSSkey`. This
key is deleted during runtime finalization, which may happen
concurrently with a call to `_PyThreadState_Attach`.
The earlier `tstate_try/wait_attach` ensures that the thread is blocked
before it attempts to access the deleted `autoTSSkey`.
This fixes a TSAN reported data race in
`test_threading.test_import_from_another_thread`.
Windows and macOS require precomputing a "timebase" in order to convert
OS timestamps into nanoseconds. Retrieve and compute this value during
runtime initialization to avoid data races when accessing the time.
Add two optional, traling elements in the AF_BLUETOOTH socket address tuple:
- l2_cid, to allow e.g raw LE ATT connections
- l2_bdaddr_type. To be able to connect L2CAP sockets to Bluetooth LE devices,
the l2_bdaddr_type must be set to BDADDR_LE_PUBLIC or BDADDR_LE_RANDOM.
