gh-91960: Skip test_gdb if gdb cannot retrive Python frames (GH-108999)
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.

* gh-108834: regrtest reruns failed tests in subprocesses (#108839)
When using --rerun option, regrtest now re-runs failed tests
in verbose mode in fresh worker processes to have more
deterministic behavior. So it can write its final report even
if a test killed a worker progress.
Add --fail-rerun option to regrtest: exit with non-zero exit code
if a test failed pass passed when re-run in verbose mode (in a
fresh process). That's now more useful since tests can pass
when re-run in a fresh worker progress, whereas they failed
when run after other tests when tests are run sequentially.
Rename --verbose2 option (-w) to --rerun. Keep --verbose2 as a
deprecated alias.
Changes:
* Fix and enhance statistics in regrtest summary. Add "(filtered)"
when --match and/or --ignore options are used.
* Add RunTests class.
* Add TestResult.get_rerun_match_tests() method
* Rewrite code to serialize/deserialize worker arguments as JSON
using a new WorkerJob class.
* Fix stats when a test is run with --forever --rerun.
* If failed test names cannot be parsed, log a warning and don't
filter tests.
* test_regrtest.test_rerun_success() now uses a marker file, since
the test is re-run in a separated process.
* Add tests on normalize_test_name() function.
* Add test_success() and test_skip() tests to test_regrtest.
(cherry picked from commit 31c2945f14)
* gh-108834: regrtest --fail-rerun exits with code 5 (#108896)

gh-108822: regrtest computes statistics (#108793)
test_netrc, test_pep646_syntax and test_xml_etree now return results

Changes:
* Rewrite TestResult as a dataclass with a new State class.
* Add test.support.TestStats class and Regrtest.stats_dict attribute.
* libregrtest.runtest functions now modify a TestResult instance
in-place.
* libregrtest summary lists the number of run tests and skipped
tests, and denied resources.
* Add TestResult.has_meaningful_duration() method.
* Compute TestResult duration in the upper function.
* Use time.perf_counter() instead of time.monotonic().
* Regrtest: rename 'resource_denieds' attribute to 'resource_denied'.
* Rename CHILD_ERROR to MULTIPROCESSING_ERROR.
* Use match/case syntadx to have different code depending on the
test state.
Notes on the backport: doctest.TestResults.skipped is a new feature
in Python 3.13, so don't use it in the backport.

gh-108682: [Enum] raise TypeError if super().__new__ called in custom __new__ (GH-108704)
When overriding the `__new__` method of an enum, the underlying data type should be created directly; i.e. .
member = object.__new__(cls)
member = int.__new__(cls, value)
member = str.__new__(cls, value)
Calling `super().__new__()` finds the lookup version of `Enum.__new__`, and will now raise an exception when detected.

gh-108550: Speed up sqlite3 tests (GH-108551)
Refactor the CLI so we can easily invoke it and mock command-line
arguments. Adapt the CLI tests so we no longer have to launch a
separate process.
Disable the busy handler for all concurrency tests; we have full
control over the order of the SQLite C API calls, so we can safely
do this.
The sqlite3 test suite now completes ~8 times faster than before.

* In preauth tests of test_ssl, explicitly break reference cycles
invoving SingleConnectionTestServerThread to make sure that the
thread is deleted. Otherwise, the test marks the environment as
altered because the threading module sees a "dangling thread"
(SingleConnectionTestServerThread). This test leak was introduced
by the test added for the fix of issue gh-108310.
* Use support.SHORT_TIMEOUT instead of hardcoded 1.0 or 2.0 seconds
timeout.
* SingleConnectionTestServerThread.run() catchs TimeoutError
* Fix a race condition (missing synchronization) in
test_preauth_data_to_tls_client(): the server now waits until the
client connect() completed in call_after_accept().
* test_https_client_non_tls_response_ignored() calls server.join()
explicitly.
* Replace "localhost" with server.listener.getsockname()[0].

Instances of `ssl.SSLSocket` were vulnerable to a bypass of the TLS handshake
and included protections (like certificate verification) and treating sent
unencrypted data as if it were post-handshake TLS encrypted data.
The vulnerability is caused when a socket is connected, data is sent by the
malicious peer and stored in a buffer, and then the malicious peer closes the
socket within a small timing window before the other peers’ TLS handshake can
begin. After this sequence of events the closed socket will not immediately
attempt a TLS handshake due to not being connected but will also allow the
buffered data to be read as if a successful TLS handshake had occurred.
