* GH-128682: Stronger checking of `PyStackRef_CLOSE` and `DEAD`. (GH-128683)Mark Shannon2025-01-131-0/+12

* gh-128150: Improve performances of `uuid.uuid*` constructor functions. (#128151)Bénédikt Tran2025-01-131-27/+58
| | | | | We introduce a private constructor `UUID._from_int()` for RFC 4122/9562 UUIDs, which takes the integral UUID value as input. The latter must have correctly set its variant and version bits. We also make `UUID.__init__()` slightly more efficient.
* GH-124483: Mark `Py_DECREF`, etc. as escaping for the JIT (GH-128678)Mark Shannon2025-01-131-0/+19

* gh-128377: Skip `test_cmd_line.test_non_interactive_output_buffering` when ↵Yan Yanchii2025-01-121-0/+2
| | | | | | | `PYTHONUNBUFFERED=1` (#128378) The `test_cmd_line.test_non_interactive_output_buffering` test assumes a buffered `stdio` without checking the `PYTHONUNBUFFERED` value. Instead of changing the environment variable for the duration of the test, it is better to simply skip it.
* GH-128520: Divide pathlib ABCs into three classes (#128523)Barney Gale2025-01-115-307/+317
| | | | | | | | | | | | In the private pathlib ABCs, rename `PurePathBase` to `JoinablePath`, and split `PathBase` into `ReadablePath` and `WritablePath`. This improves the API fit for read-only virtual filesystems. The split of `PathBase` entails a similar split of `CopyWorker` (implements copying) and the test cases in `test_pathlib_abc`. In a later patch, we'll make `WritablePath` inherit directly from `JoinablePath` rather than `ReadablePath`. For a couple of reasons, this isn't quite possible yet.

* gh-128388: pyrepl on Windows: add meta and ctrl+arrow keybindings (GH-128389)Paulie Peña2025-01-101-16/+26
| | | | | | | | | | | | Fix `Lib/_pyrepl/windows_console.py` to support more keybindings, like the `Ctrl`+`←` and `Ctrl`+`→` word-skipping keybindings and those with meta (i.e. Alt), e.g. to `kill-word` or `backward-kill-word`. Specifics: if Ctrl is pressed, emit "ctrl left" and "ctrl right" instead of just "left" or "right," and if Meta/Alt is pressed, emit the special key code for meta before emitting the other key that was pressed.

* gh-98188: Fix EmailMessage.get_payload to decode data when CTE value has ↵RanKKI2025-01-063-2/+55
| | | | | | | | | | | extra text (#127547) Up to this point message handling has been very strict with regards to content encoding values: mixed case was accepted, but trailing blanks or other text would cause decoding failure, even if the first token was a valid encoding. By Postel's Rule we should go ahead and decode as long as we can recognize that first token. We have not thought of any security or backward compatibility concerns with this fix. This fix does introduce a new technique/pattern to the Message code: we look to see if the header has a 'cte' attribute, and if so we use that. This effectively promotes the header API exposed by HeaderRegistry to an API that any header parser "should" support. This seems like a reasonable thing to do. It is not, however, a requirement, as the string value of the header is still used if there is no cte attribute. The full fix (ignore any trailing blanks or blank-separated trailing text) applies only to the non-compat32 API. compat32 is only fixed to the extent that it now ignores trailing spaces. Note that the HeaderRegistry parsing still records a HeaderDefect if there is extra text. Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com>

* pathlib tests: create `walk()` test hierarchy without using class under test ↵Barney Gale2025-01-042-39/+58
| | | | | | | | (#128338) In the tests for `pathlib.Path.walk()`, avoid using the path class under test (`self.cls`) in test setup. Instead we use `os` functions in `test_pathlib`, and direct manipulation of `DummyPath` internal data in `test_pathlib_abc`.
* GH-127381: pathlib ABCs: remove `PathBase.move()` and `move_into()` (#128337)Barney Gale2025-01-044-153/+148
| | | | | These methods combine `_delete()` and `copy()`, but `_delete()` isn't part of the public interface, and it's unlikely to be added until the pathlib ABCs are made official, or perhaps even later.
