If other exception was raised during exiting an expired
asyncio.timeout() block, insert TimeoutError in the exception context
just above the CancelledError.
winfo_id() converts the result of "winfo id" command to integer, but
"winfo pathname" command requires an argument to be a hexadecimal number
on Win64.
When an `StopIteration` raises into `asyncio.Future`, this will cause
a thread to hang. This commit address this by not raising an exception
and silently transforming the `StopIteration` with a `RuntimeError`,
which the caller can reconstruct from `fut.exception().__cause__`
Refuse to guess what a user means when they initialise a pathlib ABC
without any positional arguments. In mainline pathlib it's normalised to
`.`, but in the ABCs this guess isn't appropriate; for example, the path
type may not represent the current directory as `.`, or may have no concept
of a "current directory" at all.
Apply pathlib's normalization and performance tuning in `pathlib.PurePath`, but not `pathlib._abc.PurePathBase`.
With this change, the pathlib ABCs do not normalize away alternate path separators, empty segments, or dot segments. A single string given to the initialiser will round-trip by default, i.e. `str(PurePathBase(my_string)) == my_string`. Implementors can set their own path domain-specific normalization scheme by overriding `__str__()`
Eliminating path normalization makes maintaining and caching the path's parts and string representation both optional and not very useful, so this commit moves the `_drv`, `_root`, `_tail_cached` and `_str` slots from `PurePathBase` to `PurePath`. Only `_raw_paths` and `_resolving` slots remain in `PurePathBase`. This frees the ABCs from the burden of some of pathlib's hardest-to-understand code.
Restore full battle-tested implementations of `PurePath.[is_]relative_to()`. These were recently split up in 3375dfe and a15a773.
In `PurePathBase`, add entirely new implementations based on `_stack`, which itself calls `pathmod.split()` repeatedly to disassemble a path. These new implementations preserve features like trailing slashes where possible, while still observing that a `..` segment cannot be added to traverse an empty or `.` segment in *walk_up* mode. They do not rely on `parents` nor `__eq__()`, nor do they spin up temporary path objects.
Unfortunately calling `pathmod.relpath()` isn't an option, as it calls `abspath()` and in turn `os.getcwd()`, which is impure.
Implement `parts` using `_stack`, which itself calls `pathmod.split()`
repeatedly. This avoids use of `_tail`, which will be moved to `PurePath`
shortly.

Determine the support of the Kyiv timezone by checking the result of
astimezone() which uses the system tz database and not the one

- Add `__slots__` to dummy path classes.
- Return namedtuple rather than `os.stat_result` from `DummyPath.stat()`.
- Reduce maximum symlink count in `DummyPathWithSymlinks.resolve()`.
`PurePathBase` does not define `__eq__()`, and so we have no business checking path equality in `test_eq_common` and `test_equivalences`. The tests only pass at the moment because we define the test class's `__eq__()` for use elsewhere.
Also move `test_parse_path_common` into the main pathlib test suite. It exercises a private `_parse_path()` method that will be moved to `PurePath` soon.
Lastly move a couple more tests concerned with optimisations and path normalisation.
It can be used to set the location of a .python_history file

Replace use of `_from_parsed_parts()` with `with_segments()` in
`PurePathBase.relative_to()`, and move the assignment of `_drv`, `_root`
and `_tail_cached` slots into `PurePath.relative_to()`.
Slightly improve `pathlib.Path.glob()` tests for symlink loop handling
When filtering results, ignore paths with more than one `linkD/` segment,
rather than all paths below the first `linkD/` segment. This allows us
to test that other paths under `linkD/` are correctly returned.
Split test cases for invalid names into dedicated test methods. This will
make it easier to refactor tests for invalid name handling in ABCs later.
No change of coverage, just a change of test suite organisation.
The `DummyPurePath` and `DummyPath` test classes are simple subclasses of
`PurePathBase` and `PathBase`. This commit adds `__repr__()` methods to the
dummy classes, which makes debugging test failures less painful.
Raise auditing events in `pathlib.Path.glob()`, `rglob()` and `walk()`,
but not in `pathlib._abc.PathBase` methods. Also move generation of a
deprecation warning into `pathlib.Path` so it gets the right stack level.
This splits part of Modules/gcmodule.c of into Python/gc.c, which

- Only attempt to figure out whether protocol members are "method members" or not if the class is marked as a runtime protocol. This information is irrelevant for non-runtime protocols; we can safely skip the risky introspection for them.
- Only do the risky getattr() calls in one place (the runtime_checkable class decorator), rather than in three places (_ProtocolMeta.__init__, _ProtocolMeta.__instancecheck__ and _ProtocolMeta.__subclasscheck__). This reduces the number of locations in typing.py where the risky introspection could go wrong.
- For runtime protocols, if determining whether a protocol member is callable or not fails, give a better error message. I think it's reasonable for us to reject runtime protocols that have members which raise strange exceptions when you try to access them. PEP-544 clearly states that all protocol member must be callable for issubclass() calls against the protocol to be valid -- and if a member raises when we try to access it, there's no way for us to figure out whether it's a callable member or not!

Run expensive tests for walking and globbing from `test_pathlib` but not
`test_pathlib_abc`. The ABCs are not as tightly optimised as the classes
in top-level `pathlib`, and so these tests are taking rather a long time on
some buildbots. Coverage of the main `pathlib` classes should suffice.
Rework error handling in the C preprocessor helper. Instead of monkey-
patching the cpp.Monitor.fail() method from within clinic.py, rewrite
cpp.py to use a subclass of the ClinicError exception. As a side-effect,
ClinicError is moved into Tools/clinic/libclinic/errors.py.
Yak-shaving in preparation for putting cpp.py into libclinic.
The `pathlib._abc` module will be made available as a PyPI backport
supporting Python 3.8+. The `warnings._deprecated()` function was only
added last year, and it's private from an external package perspective, so
here we switch to `warnings.warn()` instead.
Do not use the locale-specific default encoding in `PathBase.read_text()`
and `write_text()`. Locale settings shouldn't influence the operation of
these base classes, which are intended mostly for implementing rich paths
on *nonlocal* filesystems.

This fixes a divergence between the Python and C implementations of pickle

representation of strings involving characters that have to be escaped.
In case the spawned process is setuid, we may not be able to send
signals to it, in which case our .kill() call will raise
PermissionError.
Ignore that in order to avoid .close() raising an exception. Hopefully
the process will exit as a result of receiving EOF on its stdin.
Move the following global helpers into libclinic:
- format_escape()
- normalize_snippet()
- wrap_declarations()
Also move strip_leading_and_trailing_blank_lines() and make it internal to libclinic.
Previously it worked differently if dst is a symbolic link:
it modified the permission bits of dst itself rather than the file
it points to if follow_symlinks is true or src is not a symbolic link,
and did nothing if follow_symlinks is false and src is a symbolic link.
Also document similar changes in shutil.copystat().

Change the value of `pathlib._abc.PurePathBase.pathmod` from `os.path` to
`posixpath`.
User subclasses of `PurePathBase` and `PathBase` previously used the host
OS's path syntax, e.g. backslashes as separators on Windows. This is wrong
in most use cases, and likely to catch developers out unless they test on
both Windows and non-Windows machines.
In this patch we change the default to POSIX syntax, regardless of OS. This
is somewhat arguable (why not make all aspects of syntax abstract and
individually configurable?) but an improvement all the same.
This change has no effect on `PurePath`, `Path`, nor their subclasses. Only
private APIs are affected.
`PurePathBase.__repr__()` produces a string like `MyPath('/foo')`. This
repr is incorrect/misleading when a subclass's `__init__()` method is
customized, which I expect to be the very common.
This commit moves the `__repr__()` method to `PurePath`, leaving
`PurePathBase` with the default `object` repr.
No user-facing changes because the `pathlib._abc` module remains private.

The installation of XQuartz on macOS will unconditionally
set the $DISPLAY variable. The X11 server will be launched
when a program tries to access the display. This results
in launching the X11 server when using the webbrowser module,
even though X11 browsers won't be used in practice.
The 'version' directive was introduced with gh-63929 in Nov 2013. It has
not been in use in the CPython code base, and the 'version' variable has
never been bumped.
When wrapped, `_SSLProtocolTransport._force_close(exc)` is called just like in the unwrapped scenario `_SelectorTransport._force_close(exc)` or `_ProactorBasePipeTransport._force_close(exc)` would be called, except here the exception needs to be passed through the `SSLProtocol._abort()` method, which didn't accept an exception object.
This commit ensures that this path works, in the same way that the uvloop implementation of SSLProto passes on the exception (on which the current implementation of SSLProto is based).
Change _osx_support.get_platform_osx() to make sure that the
version number in the result includes at least a major and
minor version (e.g. 14.2) even if MACOSX_DEPLOYMENT_TARGET is
set to just a major version (e.g. 14).
This matches the versions expected by pip when selecting
appropriate wheels for installation.
Add support for `os.POSIX_SPAWN_CLOSEFROM` and

Store the test base directory as a class attribute named `base` rather than
module constants named `BASE`.
The base directory is a local file path, and therefore not ideally suited
to the pathlib ABC tests. In a future commit we'll change its value in
`test_pathlib_abc.py` such that it points to a totally fictitious path, which
will help to ensure we're not touching the local filesystem.

On Windows, Process.terminate() no longer sets the returncode
attribute to always call WaitForSingleObject() in Process.wait().
Previously, sometimes the process was still running after
TerminateProcess() even if GetExitCodeProcess() is not STILL_ACTIVE.
It was raised in two cases:
* in the import statement when looking up __import__
* in pickling some builtin type when looking up built-ins iter, getattr, etc.
This affects task creation through either `asyncio.create_task()` or `TaskGroup.create_task()` -- the redundant call to `task.set_name()` is skipped. We still call `set_name()` when a task factory is involved, because the task factory call signature (unfortunately) doesn't take a `name` argument.
We need the TracebackException of uncaught exceptions for a single purpose: the error display. Thus we only need to pass the formatted error display between interpreters. Passing a pickled TracebackException is overkill.
When an exception is uncaught in Interpreter.exec_sync(), it helps to show that exception's error display if uncaught in the calling interpreter. We do so here by generating a TracebackException in the subinterpreter and passing it between interpreters using pickle.

Move `_PurePathBase` and `_PathBase` to a new `pathlib._abc` module, and
drop the underscores from the class names.
Tests are mostly left alone in this commit, but they'll be similarly split
in a subsequent commit.
The `pathlib._abc` module will be published as an independent PyPI package
(similar to how `zipfile._path` is published as `zipp`), to be refined
and stabilised prior to its possible addition to the standard library.
Regression test that vfork is used when expected by subprocess.
This is written integration test style, it uses strace if it is present and appears to work to find out what system call actually gets used in different scenarios.
Test coverage is added for the default behavior and that of each of the specific arguments that must disable the use of vfork. obviously not an entire test matrix, but it covers the most important aspects.
If there are ever issues with this test being flaky or failing on new platforms, rather than try and adapt it for all possible platforms, feel free to narrow the range it gets tested on when appropriate. That is not likely to reduce coverage.
Add private `pathlib._PurePathBase` class: a private superclass of both `PurePath` and `_PathBase`. Unlike `PurePath`, it does not define any of these special methods: `__fspath__`, `__bytes__`, `__reduce__`, `__hash__`, `__eq__`, `__lt__`, `__le__`, `__gt__`, `__ge__`. Its initializer and path joining methods accept only strings, not os.PathLike objects more broadly.
This is important for supporting *virtual paths*: user subclasses of `_PathBase` that provide access to archive files, FTP servers, etc. In these classes, the above methods should be implemented by users only as appropriate, with due consideration for the hash/equality of any backing objects, such as file objects or sockets.
In `test_pathlib`, the `check_drive_root_parts` test methods evaluated
both joining and parsing/normalisation of paths. This dates from a time
when pathlib implemented both functions itself, but nowadays path joining
is done with `posixpath.join()` and `ntpath.join()`.
This commit moves the joining-related test cases into `test_posixpath` and
`test_ntpath`.
If the input prompt to the builtin input function on terminal has any null
character, then raise ValueError instead of silently truncating it.

Restore `subprocess`'s intended use of `vfork()` by default for performance on Linux;
also fixes the behavior of `extra_groups=[]` which was unintentionally broken in 3.12.0:
Fixed a performance regression in 3.12's :mod:`subprocess` on Linux where it
would no longer use the fast-path ``vfork()`` system call when it could have
due to a logic bug, instead falling back to the safe but slower ``fork()``.
Also fixed a security bug introduced in 3.12.0. If a value of ``extra_groups=[]``
was passed to :mod:`subprocess.Popen` or related APIs, the underlying
``setgroups(0, NULL)`` system call to clear the groups list would not be made
in the child process prior to ``exec()``.
The security issue was identified via code inspection in the process of
fixing the first bug. Thanks to @vain for the detailed report and
analysis in the initial bug on Github.

up the environment changes the script makes. Before that, it checks to
see if the shell running the script is bash or zsh.
`hash -r` is specified by POSIX and is not exclusive to bash and zsh.
This guard prevents the script from calling `hash -r` in other
`#!/bin/sh`-compatible shells like dash.

Re-arrange `pathlib.PurePath` methods in source code. No other changes.
The `PurePath` implementations of certain special methods, such as
`__eq__()` and `__hash__()`, are not usually applicable to user subclasses
of `_PathBase`. To facilitate their removal, another patch will split the
`PurePath` class into `_PurePathBase` and `PurePath`, with the latter
providing these special methods.
This patch prepares the ground for splitting `PurePath`. It's similar to
e8d77b0, which preceded splitting `Path`. By churning the methods here,
subsequent patches will be easier to review and less likely to break
things.

Add `glob.translate()` function that converts a pathname with shell wildcards to a regular expression. The regular expression is used by pathlib to implement `match()` and `glob()`.
This function differs from `fnmatch.translate()` in that wildcards do not match path separators by default, and that a `*` pattern segment matches precisely one path segment. When *recursive* is set to true, `**` pattern segments match any number of path segments, and `**` cannot appear outside its own segment.
In pathlib, this change speeds up directory walking (because `_make_child_relpath()` does less work), makes path objects smaller (they don't need a `_lines` slot), and removes the need for some gnarly code.

as when iterating over a Maildir to find messages with specific flags.

Now all results from worker processes are aggregated and
displayed together as a summary at the end of a regrtest run.
The traditional trace is left in place for use with sequential
in-process test runs but now raises a warning that those
numbers are not precise.
`-T -j` requires `--with-pydebug` as it relies on `-Xpresite=`.
The random module now imports the _sha2 module lazily in the
Random.seed() method for str, bytes and bytearray seeds. It also
imports lazily the warnings module in the _randbelow() method for
classes without getrandbits(). Lazy import makes Python startup
faster and reduces the number of imported modules at startup.
In most cases, doctest is not needed. So don't always import it at
startup. The change reduces the number of modules already
imported when a test is run.
