* gh-58749: Remove incorrect language spec claims about the global statement ↵Beomsoo Kim2024-11-123-44/+191
| | | | | | | | (GH-126523) * Removes erroneous explanation of the `global` statement restrictions; a name declared as global can be subsequently bound using any kind of name binding operation. * Updates `test_global.py` to also test various name-binding scenarios for global variables to ensure correct behavior
* gh-76785: Improved Subinterpreters Compatibility with 3.12 (1/2) (gh-126704)Eric Snow2024-11-119-43/+55
| | | | | | | | | These changes makes it easier to backport the _interpreters, _interpqueues, and _interpchannels modules to Python 3.12. This involves the following: * rename several structs and typedefs * add several typedefs * stop using the PyThreadState.state field directly in parking_lot.c

| | | | | | | | | | | | | | ``--enable-experimental-jit`` option (#126648) Add an entry for the ``--enable-experimental-jit`` option in ``Doc/using/configure.rst``. This was added as an experimental option in CPython 3.13. Possible values for it: * `no` - don't build the JIT. * `yes` - build the JIT. * `yes-off` - build the JIT but disable it by default. * `interpreter` - don't build the JIT but enable tier 2 interpreter instead.

* gh-117378: Only run the new multiprocessing SysPath test when appropriate ↵Gregory P. Smith2024-11-101-29/+30
| | | | | | | | | (GH-126635) The first version had it running two forkserver and one spawn tests underneath each of the _fork, _forkserver, and _spawn test suites that build off the generic one. This adds to the existing complexity of the multiprocessing test suite by offering BaseTestCase classes another attribute to control which suites they are invoked under. Practicality vs purity here. :/ Net result: we don't over-run the new test and their internal logic is simplified.
* Skip test in test_socket.py if `sys.getrefcount` isn't available (#126640)CF Bolz-Tereick2024-11-101-0/+2
| | | Skip `testMakefileCloseSocketDestroy` test if `sys.getrefcount` isn't available. This is necessary for PyPy and other Python implementations that do not have `sys.getrefcount`.
* gh-126565: Skip `zipfile.Path.exists` check in write mode (#126576)Jan Hicken2024-11-102-1/+2
| | | | | | | | | | | When `zipfile.Path.open` is called, the implementation will check whether the path already exists in the ZIP file. However, this check is only required when the ZIP file is in read mode. By swapping arguments of the `and` operator, the short-circuiting will prevent the check from being run in write mode. This change will improve the performance of `open()`, because checking whether a file exists is slow in write mode, especially when the archive has many members.

* gh-117378: Fix multiprocessing forkserver preload sys.path inheritance. ↵Gregory P. Smith2024-11-093-0/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-126538) gh-117378: Fix multiprocessing forkserver preload sys.path inheritance. `sys.path` was not properly being sent from the parent process when launching the multiprocessing forkserver process to preload imports. This bug has been there since the forkserver start method was introduced in Python 3.4. It was always _supposed_ to inherit `sys.path` the same way the spawn method does. Observable behavior change: A `''` value in `sys.path` will now be replaced in the forkserver's `sys.path` with an absolute pathname `os.path.abspath(os.getcwd())` saved at the time that `multiprocessing` was imported in the parent process as it already was when using the spawn start method. **This will only be observable during forkserver preload imports**. The code invoked before calling things in another process already correctly sets `sys.path`. Which is likely why this went unnoticed for so long as a mere performance issue in some configurations. A workaround for the bug on impacted Pythons is to set PYTHONPATH in the environment before multiprocessing's forkserver process was started. Not perfect as that is then inherited by other children, etc, but likely good enough for many people's purposes. Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* pathlib ABCs: tighten up `resolve()` and `absolute()` (#126611)Barney Gale2024-11-093-32/+53
| | | | | | | | | | | | In `PathBase.resolve()`, raise `UnsupportedOperation` if a non-POSIX path parser is used (our implementation uses `posixpath._realpath()`, which produces incorrect results for non-POSIX path flavours.) Also tweak code to call `self.absolute()` upfront rather than supplying an emulated `getcwd()` function. Adjust `PathBase.absolute()` to work somewhat like `resolve()`. If a POSIX path parser is used, we treat the root directory as the current directory. This is the simplest useful behaviour for concrete path types without a current directory cursor.
* pathlib ABCs: support initializing paths with no arguments (#126608)Barney Gale2024-11-092-9/+8
| | | | | | | | In the past I've equivocated about whether to require at least one argument in the `PurePathBase` (and `PathBase`) initializer, and what the default should be if we make it optional. I now have a local use case that has persuaded me to make it optional and default to the empty string (a `zipp.Path`-like class that treats relative and absolute paths similarly.) Happily this brings the base class more in line with `PurePath` and `Path`.

* GH-126212: Fix removal of slashes in file URIs on Windows (#126214)Barney Gale2024-11-083-21/+18
| | | | | | Adjust `urllib.request.pathname2url()` and `url2pathname()` so that they don't remove slashes from Windows DOS drive paths and URLs. There was no basis for this behaviour, and it conflicts with how UNC and POSIX paths are handled.

| | | | | | | | | | | order (#126569) Before #126387, if we didn't detect float word order we'd raise the following configure error: Unknown float word ordering.

* gh-122943: Rework support of var-positional parameter in Argument Clinic ↵Serhiy Storchaka2024-11-0722-662/+1597
| | | | | | | | | | | | | | | | | | (GH-122945) Move creation of a tuple for var-positional parameter out of _PyArg_UnpackKeywordsWithVararg(). Merge _PyArg_UnpackKeywordsWithVararg() with _PyArg_UnpackKeywords(). Add a new parameter in _PyArg_UnpackKeywords(). The "parameters" and "converters" attributes of ParseArgsCodeGen no longer contain the var-positional parameter. It is now available as the "varpos" attribute. Optimize code generation for var-positional parameter and reuse the same generating code for functions with and without keyword parameters. Add special converters for var-positional parameter. "tuple" represents it as a Python tuple and "array" represents it as a continuous array of PyObject*. "object" is a temporary alias of "tuple".
