gh-128377: Skip `test_cmd_line.test_non_interactive_output_buffering` when `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)
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-127257: Add hex code to ssl "unknown error" message (GH-127360)
* ssl: Add hex error code to "unknown error" messages
To make it easier to vary the individual parts of the message,
replace the if-ladder with constant format strings by building
the string piece-wise with PyUnicodeWriter.
Use "unknown error (0x%x)" rather than just "unknown error" if we
can't get a better error message. (Hex makes sense as the error
includes two packed parts.)

gh-128388: pyrepl on Windows: add meta and ctrl+arrow keybindings (GH-128389)
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 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.

Add a separate benchmark that measures the effect of
`_PyObject_LookupSpecial()` on scaling.
In the process of cleaning up the scaling benchmarks for inclusion, I
unintentionally changed the "cmodule_function" benchmark to pass an
`int` to `math.floor()` instead of a `float`, which causes it to use the
`_PyObject_LookupSpecial()` code path. `_PyObject_LookupSpecial()` has
its own scaling issues that we want to measure separately from calling a
function on a C module.
