* GH-102613: Improve performance of `pathlib.Path.rglob()` (GH-104244)Barney Gale2023-05-072-18/+42
| | | | | | | | | | Stop de-duplicating results in `_RecursiveWildcardSelector`. A new `_DoubleRecursiveWildcardSelector` class is introduced which performs de-duplication, but this is used _only_ for patterns with multiple non-adjacent `**` segments, such as `path.glob('**/foo/**')`. By avoiding the use of a set, `PurePath.__hash__()` is not called, and so paths do not need to be stringified and case-normalised. Also merge adjacent '**' segments in patterns.

* GH-89812: Churn `pathlib.Path` methods (GH-104243)Barney Gale2023-05-071-303/+303
| | | | | | | | | | | | | | | Re-arrange `pathlib.Path` methods in source code. No other changes. The methods are arranged as follows: 1. `stat()` and dependants (`exists()`, `is_dir()`, etc) 2. `open()` and dependants (`read_text()`, `write_bytes()`, etc) 3. `iterdir()` and dependants (`glob()`, `walk()`, etc) 4. All other `Path` methods This patch prepares the ground for a new `_AbstractPath` class, which will support the methods in groups 1, 2 and 3 above. By churning the methods here, subsequent patches will be easier to review and less likely to break things.

* gh-99113: Add a check for Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104206)Eric Snow2023-05-062-0/+22
| | | Py_MOD_PER_INTERPRETER_GIL_SUPPORTED is a new supported value for Py_mod_multiple_interpreters, added in gh-104205.
* GH-103548: Improve performance of `pathlib.Path.[is_]absolute()` (GH-103549)Barney Gale2023-05-061-1/+10
| | | | Improve performance of `pathlib.Path.absolute()` and `cwd()` by joining paths only when necessary. Also improve performance of `PurePath.is_absolute()` on Posix by skipping path parsing and normalization.
* gh-90953: Emit deprecation warnings for `ast` features deprecated in Python ↵Alex Waygood2023-05-062-135/+455
| | | | | | | 3.8 (#104199) `ast.Num`, `ast.Str`, `ast.Bytes`, `ast.Ellipsis` and `ast.NameConstant` now all emit deprecation warnings on import, access, instantation or `isinstance()` checks. Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

* Rewrite the turtledemo makeGraphFrame method (#104224)Terry Jan Reedy2023-05-061-10/+14
| | | | | | | Replace `self._canvas` and `self.scanvas`, both bound to `canvas`, with `self.canvas, which is accessed in other methods. Replace `_s_` with `screen` and `_s_._canvas` with `canvas`. Add a comment explaining the unorthodox use of function turtle.Screen and singleton class turtle._Screen.
* gh-65772: Clean-up turtle module (#104218)Terry Jan Reedy2023-05-061-40/+21
| | | | | | | | | | | | | | | | | | | | | | | * Remove the unused, private, and undocumented name `_ver` and the commented-out `print` call. * Don't add math functions to `__all__`. Beginners should learn to `import math` to access them. * Gregor Lindel, who wrote this version of turtle, dropped plans to implement turtle on another toolkit at least a decade ago. Drop `_dot` code preparing for this, but add a hint comment. * `_Screen` is meant to be a singleton class. To enforce that, it needs either a `__new__` that returns the singleton or `else...raise` in `__iter__`. Merely removing the `if` clauses as suggested might break something if a user were to call `_Screen` directly. Leave the code alone until a problem is evident. * Turtledemo injects into _Screen both _root and _canvas, configured as it needs them to be. Making _canvas an `__init__` option would require skipping some but not all of the lines under 'if _Screen._canvas is None:`. Leave working code alone.
* gh-104144: Skip scheduling a done callback if a TaskGroup task completes ↵Itamar Ostricher2023-05-051-2/+8

* gh-99113: Add PyInterpreterConfig.own_gil (gh-104204)Eric Snow2023-05-054-10/+29
| | | | | We also add PyInterpreterState.ceval.own_gil to record if the interpreter actually has its own GIL. Note that for now we don't actually respect own_gil; all interpreters still share the one GIL. However, PyInterpreterState.ceval.own_gil does reflect PyInterpreterConfig.own_gil. That lie is a temporary one that we will fix when the GIL really becomes per-interpreter.
* gh-104108: Add the Py_mod_multiple_interpreters Module Def Slot (gh-104148)Eric Snow2023-05-051-21/+61
| | | I'll be adding a value to indicate support for per-interpreter GIL in gh-99114.
* GH-100479: Add `pathlib.PurePath.with_segments()` (GH-103975)Barney Gale2023-05-052-45/+73
| | | | | Add `pathlib.PurePath.with_segments()`, which creates a path object from arguments. This method is called whenever a derivative path is created, such as from `pathlib.PurePath.parent`. Subclasses may override this method to share information between path objects. Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>

* gh-102795: Fix use of poll in test_epoll's test_control_and_wait (#102796)Kevin Krakauer2023-05-041-4/+11
| | | | | | | | | | This test can fail unnecessarily. In the test we wait for events on two file descriptors. This is done in a single call to select.epoll's poll() function. However, it is valid for the OS to return only one event via poll() and the next via a subsequent call to poll(). This rarely happens, but it can cause the test to fail despite properly functioning polling. Instead, we poll a second time when necessary.
