gh-138584: Increase test coverage for `collections.UserList` (GH-138590)
Some common tests in `test.list_tests.CommonTest` explicitly tested `list`
instead of testing the underlying list-like type defined in `type2test`.

gh-118981: multiprocessing.popen_spawn_posix, fix potential hang (gh-118982)
fix potential hang.
It can happen that the child crashes right in the beginning for whatever reason. In this case, the parent will hang when writing into the pipe, because the child fd is not closed yet.
The normal pattern is to close the child fds right after the child proc is forked/executed/spawned, so when the child dies, then also the pipes will be closed, and there will be no hang (the parent gets SIGPIPE instead).

* [3.13] gh-87135: Hang non-main threads that attempt to acquire the GIL during finalization (GH-105805)
Instead of surprise crashes and memory corruption, we now hang threads that attempt to re-enter the Python interpreter after Python runtime finalization has started. These are typically daemon threads (our long standing mis-feature) but could also be threads spawned by extension modules that then try to call into Python. This marks the `PyThread_exit_thread` public C API as deprecated as there is no plausible safe way to accomplish that on any supported platform in the face of things like C++ code with finalizers anywhere on a thread's stack. Doing this was the least bad option.

The `PyEval_SetProfileAllThreads` function and other related functions
had a race condition on `tstate->c_profilefunc` that could lead to a
crash when disable profiling or tracing on all threads while another
thread is starting to profile or trace a a call.
There are still potential crashes when threads exit concurrently with
profiling or tracing be enabled/disabled across all threads.

Add test for opening an SQLite with bytes path (GH-136331)
(cherry picked from commit 1bde13b0e9)
Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
Previously, DocTest's lineno of functions and methods decorated with
functools.cache(), functools.lru_cache() and functools.cached_property()
was not properly returned (None was returned) because the
computation relied on inspect.isfunction() which does not consider the
decorated result as a function.
We now use the more generic inspect.isroutine(), as elsewhere
in doctest's logic.
Also, added a special case for functools.cached_property().

gh-137463: Update `validate_abstract_methods` in `test_collections.py` (#137464)
Update `validate_abstract_methods` in `test_collections.py`
The test for missing abstract methods in `validate_abstract_methods` incorrectly attempted to instantiate the generated class `C` with an argument (`C(name)`), which always raises a `TypeError: C() takes no arguments`. Although the test originally passes, it passes for the wrong reason.
This change makes the test correctly validate the enforcement of abstract methods in ABCs.
