* gh-102512: Turn _DummyThread into _MainThread after os.fork() called from a ↵Serhiy Storchaka2024-01-221-0/+3
| | | | | | | | | | | | | | | | | foreign thread (GH-113261) Always set a _MainThread as a main thread after os.fork() is called from a thread started not by the threading module. A new _MainThread was already set as a new main thread after fork if threading.current_thread() was not called for a foreign thread before fork. Now, if it was called before fork, the implicitly created _DummyThread will be turned into _MainThread after fork. It fixes, in particularly, an incompatibility of _DummyThread with the threading shutdown logic which relies on the main thread having tstate_lock.

* gh-114328: tty cbreak mode should not alter ICRNL (#114335)Gregory P. Smith2024-01-211-0/+4
| | | The terminal CR -> NL mapping setting should be inherited in cbreak mode as OSes do not specify altering it as part of their stty cbreak mode definition.

* GH-113225: Speed up `pathlib.Path.walk(top_down=False)` (#113693)Barney Gale2024-01-201-0/+2
| | | | | | | | | | | | | | Use `_make_child_entry()` rather than `_make_child_relpath()` to retrieve path objects for directories to visit. This saves the allocation of one path object per directory in user subclasses of `PathBase`, and avoids a second loop. This trick does not apply when walking top-down, because users can affect the walk by modifying *dirnames* in-place. A side effect of this change is that, in bottom-up mode, subdirectories of each directory are visited in reverse order, and that this order doesn't match that of the names in *dirnames*. I suspect this is fine as the order is arbitrary anyway.
* GH-79634: Accept path-like objects as pathlib glob patterns. (#114017)Barney Gale2024-01-201-0/+2
| | | | | | | | | Allow `os.PathLike` objects to be passed as patterns to `pathlib.Path.glob()` and `rglob()`. (It's already possible to use them in `PurePath.match()`) While we're in the area: - Allow empty glob patterns in `PathBase` (but not `Path`) - Speed up globbing in `PathBase` by generating paths with trailing slashes only as a final step, rather than for every intermediate directory. - Simplify and speed up handling of rare patterns involving both `**` and `..` segments.

| | | | | | | | | | `PyComplex_RealAsDouble()`/`PyComplex_ImagAsDouble` now try to convert an object to a `complex` instance using its `__complex__()` method before falling back to the ``__float__()`` method. PyComplex_ImagAsDouble() also will not silently return 0.0 for non-complex types anymore. Instead we try to call PyFloat_AsDouble() and return 0.0 only if this call is successful.

| | | | | | | | | | | | | (#113829) On Windows, `os.path.isabs()` now returns `False` when given a path that starts with exactly one (back)slash. This is more compatible with other functions in `os.path`, and with Microsoft's own documentation. Also adjust `pathlib.PureWindowsPath.is_absolute()` to call `ntpath.isabs()`, which corrects its handling of partial UNC/device paths like `//foo`. Co-authored-by: Jon Foster <jon@jon-foster.co.uk>
