Fix test_gdb on Python built with LLVM clang 16 on Linux ppc64le (ex:
Fedora 38). Search patterns in gdb "bt" command output to detect
when gdb fails to retrieve the traceback. For example, skip a test if
"Backtrace stopped: frame did not save the PC" is found.
libregrtest now calls random.seed() before running each test file
when -r/--randomize command line option is used. Moreover, it's also
called in worker processes. It should help to make tests more
deterministic. Previously, it was only called once in the main
process before running all test files and it was not called in worker
processes.
* Convert some f-strings to regular strings in test_regrtest when
f-string is not needed.
* Remove unused all_methods variable from test_regrtest.
* Add RunTests members are now mandatory.
libregrtest now uses a separated file descriptor to write test result
as JSON. Previously, if a test wrote debug messages late around the
JSON, the main test process failed to parse JSON.
Rename TestResult.write_json() to TestResult.write_json_into().
worker_process() no longer writes an empty line at the end. There is
no need to separate test process output from the JSON output anymore,
since JSON is now written into a separated file descriptor.
create_worker_process() now always spawn the process with
close_fds=True.
Fix _thread.start_new_thread() race condition. If a thread is created
during Python finalization, the newly spawned thread now exits
immediately instead of trying to access freed memory and lead to a
crash.
thread_run() calls PyEval_AcquireThread() which checks if the thread
must exit. The problem was that tstate was dereferenced earlier in
_PyThreadState_Bind() which leads to a crash most of the time.
Move _PyThreadState_CheckConsistency() from thread_run() to
_PyThreadState_Bind().
Fix a race condition in concurrent.futures. When a process in the
process pool was terminated abruptly (while the future was running or
pending), close the connection write end. If the call queue is
blocked on sending bytes to a worker process, closing the connection
write end interrupts the send, so the queue can be closed.
Changes:
* _ExecutorManagerThread.terminate_broken() now closes
call_queue._writer.
* multiprocessing PipeConnection.close() now interrupts
WaitForMultipleObjects() in _send_bytes() by cancelling the
overlapped operation.
Fix test_pyexpat.test_exception(): it can now be run from a directory
different than Python source code directory. Before, the test failed
in this case.
Skip the test if Modules/pyexpat.c source is not available. Skip also
the test on Python implementations other than CPython.
Fix test_site.test_underpth_basic() when the working directory
contains at least one non-ASCII character: encode the "._pth" file to
UTF-8 and enable the UTF-8 Mode to use UTF-8 for the child process
stdout.
Attempts to pickle or create a shallow or deep copy of codecs streams
now raise a TypeError.
Previously, copying failed with a RecursionError, while pickling
produced wrong results that eventually caused unpickling to fail with
a RecursionError.
Fix building the _testcapi extension on Linux AArch64 which requires
linking to libatomic when <cpython/pyatomic.h> is used: the
_Py_atomic_or_uint64() function requires libatomic
__atomic_fetch_or_8() on this platform.
The configure script now checks if linking to libatomic is needed and
generates a new LIBATOMIC variable used to build the _testcapi
extension.
Building the _testcapi extension now uses the LIBATOMIC variable in
its LDFLAGS, since Modules/_testcapi/pyatomic.c uses
<cpython/pyatomic.h>.

add guard so that ``Enum('bar')`` raises a TypeError instead of
creating a new enum class called `bar`. To create the new but
empty class, use:
huh = Enum('bar', names=())
It creates a modified copy of an object by calling the object's
__replace__() method.
It is a generalization of dataclasses.replace(), named tuple's _replace()
method and replace() methods in various classes, and supports all these
stdlib classes.
Fix a race condition in "make regen-all". The deepfreeze.c source and
files generated by Argument Clinic are now generated or updated
before generating "global objects". Previously, some identifiers may
miss depending on the order in which these files were generated.
* "make regen-global-objects": Make sure that deepfreeze.c is
generated and up to date, and always run "make clinic".
* "make clinic" no longer runs generate_global_objects.py script.
* "make regen-deepfreeze" now only updates deepfreeze.c (C file).
It doesn't build deepfreeze.o (object) anymore.
* Remove misleading messages in "make regen-global-objects" and
"make clinic". They are now outdated, these commands are now
safe to use.
* Document generates files in Doc/using/configure.rst.

* Add get_recursion_available() and get_recursion_depth() functions
to the test.support module.
* Change infinite_recursion() default max_depth from 75 to 100.
* Fix test_tomllib recursion tests for WASI buildbots: reduce the
recursion limit and compute the maximum nested array/dict depending
on the current available recursion limit.
* test.pythoninfo logs sys.getrecursionlimit().
* Enhance test_sys tests on sys.getrecursionlimit()
and sys.setrecursionlimit().

Skip test_gdb if gdb is unable to retrieve Python frame objects: if a
frame is "<optimized out>". When Python is built with "clang -Og",
gdb can fail to retrive the 'frame' parameter of
_PyEval_EvalFrameDefault(). In this case, tests like py_bt() are
likely to fail. Without getting access to Python frames,
python-gdb.py is mostly clueless on retrieving the Python traceback.
Moreover, test_gdb is no longer skipped on macOS if Python is built
with Clang.
