* Authenticate socket connection for `socket.socketpair()` fallback when the platform does not have a native `socketpair` C API. We authenticate in-process using `getsocketname` and `getpeername` (thanks to Nathaniel J Smith for that suggestion).

The tests were only checking cases where the slot wrapper was present in the initial case. They were missing when the slot wrapper was added in the additional initializations. This fixes that.
* Use compensated summation for complex sums with floating-point items.
This amends #121176.
* sum() specializations for floats and complexes now use
PyLong_AsDouble() instead of PyLong_AsLongAndOverflow() and
compensated summation as well.

Serializing objects with complex __qualname__ (such as unbound methods and
nested classes) by name no longer involves serializing parent objects by value
in pickle protocols < 4.
TSan doesn't fully recognize the synchronization via I/O, so ensure that
socket name is retrieved earlier and use a different socket for sending
the "STOP" message.
In the process of speeding up readall, A number of related tests
(ex. large file tests in test_zipfile) found problems with the
change I was making. This adds I/O tests to specifically test these
cases to help ensure they don't regress and hopefully make debugging
easier.
This is part of the improvements from
https://github.com/python/cpython/pull/121593#issuecomment-2222261986
This fixes the flakiness in:
* test_inspect_keeps_globals_from_inspected_file
* test_inspect_keeps_globals_from_inspected_module
The output already includes newlines. Adding newlines for every entry in
the output list introduces non-determinism because it added '\n' in
places where stdout is flushed or some buffer becomes full.
The regex also needed to be updated because pyrepl includes control
characters -- the visible output on each line doesn't immediately follow
a newline character.

Add *preserve_metadata* keyword-only argument to `pathlib.Path.copytree()`,
defaulting to false. When set to true, we copy timestamps, permissions,
extended attributes and flags where available, like `shutil.copystat()`.
Add a `Path.rmtree()` method that removes an entire directory tree, like
`shutil.rmtree()`. The signature of the optional *on_error* argument
matches the `Path.walk()` argument of the same name, but differs from the
*onexc* and *onerror* arguments to `shutil.rmtree()`. Consistency within
pathlib is probably more important.
In the private pathlib ABCs, we add an implementation based on `walk()`.

* Reject uop definitions that declare values as 'unused' that are already cached by prior uops
* Track which variables are defined and only load from memory when needed
* Support explicit `flush` in macro definitions.
* Make sure stack is flushed in where needed.
console.compile with the "single" param throws an exception when
there are multiple statements, never allowing to adding newlines
to a pasted code block (gh-121610)
This add a few extra checks to allow extending when in an indented
block, and tests for a few examples

Any cross-interpreter mechanism for passing objects between interpreters must be very careful to respect isolation, even when the object is effectively immutable (e.g. int, str). Here this especially relates to when an interpreter sends one of its objects, and then is destroyed while the inter-interpreter machinery (e.g. queue) still holds a reference to the object.
When I added interpreters.Queue, I dealt with that case (using an atexit hook) by silently removing all items from the queue that were added by the finalizing interpreter.
Later, while working on concurrent.futures.InterpreterPoolExecutor (gh-116430), I noticed it was somewhat surprising when items were silently removed from the queue when the originating interpreter was destroyed. (See my comment on that PR.)
It took me a little while to realize what was going on. I expect that users, which much less context than I have, would experience the same pain.
My approach, here, to improving the situation is to give users three options:
1. return a singleton (interpreters.queues.UNBOUND) from Queue.get() in place of each removed item
2. raise an exception (interpreters.queues.ItemInterpreterDestroyed) from Queue.get() in place of each removed item
3. existing behavior: silently remove each item (i.e. Queue.get() skips each one)
The default will now be (1), but users can still explicitly opt in any of them, including to the silent removal behavior.
The behavior for each item may be set with the corresponding Queue.put() call. and a queue-wide default may be set when the queue is created. (This is the same as I did for "synconly".)
They are alternate constructors which only accept numbers
(including objects with special methods __float__, __complex__
and __index__), but not strings.
It is our general practice to make new optional parameters keyword-only,
even if the existing parameters are all positional-or-keyword. Passing
this parameter as positional would look confusing and could be error-prone
if additional parameters are added in the future.
On POSIX systems, excluding macOS framework installs, the lib directory
for the free-threaded build now includes a "t" suffix to avoid conflicts
with a co-located default build installation.
When builtin static types are initialized for a subinterpreter, various "tp" slots have already been inherited (for the main interpreter). This was interfering with the logic in add_operators() (in Objects/typeobject.c), causing a wrapper to get created when it shouldn't. This change fixes that by preserving the original data from the static type struct and checking that.
