gh-119287: clarify doc on BaseExceptionGroup.derive and link to it from contextlib.suppress (GH-119657)
(cherry picked from commit 5c02ea8bae)
Co-authored-by: Irit Katriel <1055913+iritkatriel@users.noreply.github.com>
The `test_imaplib` was taking 40+ minutes in the refleak build bots because
the tests waiting on a client `self._setup()` was creating a client that
prevented progress until its connection timed out, which scaled with the
global timeout.
We should set `connect=False` for the tests that don't want `_setup()` to
create a client.

The process is expected to time out. In the refleak builds,
`support.SHORT_TIMEOUT` is often five minutes and we run the tests six
times, so test_signal was taking >30 minutes.

gh-111499: Fix PYTHONMALLOCSTATS at Python exit (#120021)
Call _PyObject_DebugMallocStats() earlier in Py_FinalizeEx(), before
the interpreter is deleted.
(cherry picked from commit 5a1205b641)
Add a dedicated subsection for `Path.stat()`-related methods, specifically
`stat()`, `lstat()`, `exists()`, `is_*()`, and `samefile()`.

- Explicit list of what it does that is different from
"just return __annotations__"
- Remove reference to PEP 563; adding the future import doesn't
do anything to type aliases, and in general it will never make
get_type_hints() less likely to fail.
- Remove example, as the Annotated docs already have a similar
example, and it's unbalanced to have one example about this
one edge case but not about other behaviors of the function.

Implement `shutil._rmtree_safe_fd()` using a list as a stack to avoid emitting recursion errors on deeply nested trees.
`shutil._rmtree_unsafe()` was fixed in a150679f90.

Revert "[3.12] gh-69214: Fix fcntl.ioctl() request type (#119498) (#119505)"
This reverts commit 078da88ad1.
The change modified how negative values, like termios.TIOCSWINSZ, was
treated and is actually backward incompatible.
The implementation basically copies LOAD_GLOBAL. Possibly it could be deduplicated,
but that seems like it may get hairy since the two operations have different operands.
This is important to fix in 3.14 for PEP 649, but it's a bug in earlier versions too,
and we should backport to 3.13 and 3.12 if possible.

gh-100117: Fix inaccuracy in documentation of the CodeObject's co_positions field. (GH-119364)

Make sure that `gilstate_counter` is not zero in when calling
`PyThreadState_Clear()`. A destructor called from `PyThreadState_Clear()` may
call back into `PyGILState_Ensure()` and `PyGILState_Release()`. If
`gilstate_counter` is zero, it will try to create a new thread state before
the current active thread state is destroyed, leading to an assertion failure
or crash.

Some of standard Tcl types were renamed, removed, or no longer
registered in Tcl 8.7/9.0. This change fixes automatic conversion of Tcl
values to Python values to avoid returning a Tcl_Obj where the primary
Python types (int, bool, str, bytes) were returned in older Tcl.

* Remove the equivalence with real+imag*1j which can be incorrect in corner
cases (non-finite numbers, the sign of zeroes).
* Separately document the three roles of the constructor: parsing a string,
converting a number, and constructing a complex from components.
* Document positional-only parameters of complex(), float(), int() and bool()
as positional-only.
* Add examples for complex() and int().
* Specify the grammar of the string for complex().
* Improve the grammar of the string for float().
* Describe more explicitly the behavior when real and/or imag arguments are
complex numbers. (This will be deprecated in future.)
(cherry picked from commit ec1ba26460)
* Share common classes.
* Use exactly representable floats and exact tests.
* Check the sign of zero components.
* Remove duplicated tests (mostly left after merging int and long).
* Reorder tests in more consistent way.
* Test more error messages.
* Add tests for missed cases.

subprocess docs: Fix semantically important typo (GH-119752)
GH-25416 accidentally replaced a reference to the *stderr* argument of

* GH-89727: Partially fix `shutil.rmtree()` recursion error on deep trees (#119634)
Make `shutil._rmtree_unsafe()` call `os.walk()`, which is implemented
without recursion.
`shutil._rmtree_safe_fd()` is not affected and can still raise a recursion
error.
