gh-109615: Fix test_tools.test_freeze SRCDIR (#109935)
Fix copy_source_tree() function of test_tools.test_freeze:
* Don't copy SRC_DIR/build/ anymore. This directory is modified by
other tests running in parallel.
* Add test.support.copy_python_src_ignore().
* Use sysconfig to get the source directory.
* Use sysconfig.get_config_var() to get CONFIG_ARGS variable.

(#109616)
gh-103053: Skip test_freeze_simple_script() on PGO build (#109591)
Skip test_freeze_simple_script() of test_tools.test_freeze if Python
is built with "./configure --enable-optimizations", which means with
Profile Guided Optimization (PGO): it just makes the test too slow.
The freeze tool is tested by many other CIs with other (faster)
compiler flags.
test.pythoninfo now gets also get_build_info() of
test.libregrtests.utils.

gh-108851: Fix tomllib recursion tests (#108853)
* 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().
Backport notes:
* Set support.infinite_recursion() minimum to 4 frames.
* test_support.test_get_recursion_depth() uses limit-2, apparently
f-string counts for 2 frames in Python 3.11.
* test_sys.test_setrecursionlimit_to_depth() tests depth+2 instead of
depth+1.

* gh-93353: regrtest checks for leaked temporary files (#93776)
When running tests with -jN, create a temporary directory per process
and mark a test as "environment changed" if a test leaks a temporary
file or directory.

* gh-93353: regrtest supports checking tmp files with -j2 (#93909)
regrtest now also implements checking for leaked temporary files and
directories when using -jN for N >= 2. Use tempfile.mkdtemp() to
create the temporary directory. Skip this check on WASI.

(root). Disable effective uid/gid syscalls and fix tests that use
chmod() current user.

* gh-95027: Fix regrtest stdout encoding on Windows (#98492)
On Windows, when the Python test suite is run with the -jN option,
the ANSI code page is now used as the encoding for the stdout
temporary file, rather than using UTF-8 which can lead to decoding
errors.
(cherry picked from commit ec1f6f5f139868dc2c1116a7c7c878c38c668d53)
* gh-98903: Test suite fails with exit code 4 if no tests ran (#98904)

* gh-82054: allow test runner to split test_asyncio to execute in parallel by sharding. (#103927)
This runs test_asyncio sub-tests in parallel using sharding from Cinder. This suite is typically the longest-pole in runs because it is a test package with a lot of further sub-tests otherwise run serially. By breaking out the sub-tests as independent modules we can run a lot more in parallel.
After porting we can see the direct impact on a multicore system.
Without this change:
Running make test is 5 min 26 seconds
With this change:
Running make test takes 3 min 39 seconds
That'll vary based on system and parallelism. On a `-j 4` run similar to what CI and buildbot systems often do, it reduced the overall test suite completion latency by 10%.
The drawbacks are that this implementation is hacky and due to the sorting of the tests it obscures when the asyncio tests occur and involves changing CPython test infrastructure but, the wall time saved it is worth it, especially in low-core count CI runs as it pulls a long tail. The win for productivity and reserved CI resource usage is significant.
Future tests that deserve to be refactored into split up suites to benefit from are test_concurrent_futures and the way the _test_multiprocessing suite gets run for all start methods. As exposed by passing the -o flag to python -m test to get a list of the 10 longest running tests.

* Display the sanitizer config in the regrtest header. (#105301)
Display the sanitizers present in libregrtest.
Having this in the CI output for tests with the relevant environment
variable displayed will help make it easier to do what we need to
create an equivalent local test run.

* gh-101634: regrtest reports decoding error as failed test (#106169)
When running the Python test suite with -jN option, if a worker stdout
cannot be decoded from the locale encoding report a failed testn so the
exitcode is non-zero.

* Cleanup libregrtest code logging ASAN_OPTIONS.
* Fix a typo on "ASAN_OPTIONS" vs "MSAN_OPTIONS".
(cherry picked from commit 3a1ac87f8f89d3206b46a0df4908afae629d669d)
* gh-108388: regrtest splits test_asyncio package (#108393)
Currently, test_asyncio package is only splitted into sub-tests when
using command "./python -m test". With this change, it's also
splitted when passing it on the command line:
"./python -m test test_asyncio".
Remove the concept of "STDTESTS". Python is now mature enough to not
have to bother with that anymore. Removing STDTESTS simplify the
code.
(cherry picked from commit 174e9da0836844a2138cc8915dd305cb2cd7a583)
* regrtest computes statistics (#108793)
test_netrc, test_pep646_syntax and test_xml_etree now return results
in the test_main() function.
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.

The test.support.wait_process() function now uses a timeout of
LONG_TIMEOUT seconds by default, instead of SHORT_TIMEOUT. It
doesn't matter if a Python buildbot is slower, it only matters that
the process completes. The timeout should just be shorter than
"forever".

- non-encodable file names are not supported by NODERAWFS layer.
- mark more tests with dependency on subprocess and multiprocessing.
Mocking does not work if the module fails to import.

Lib/test/support/import_helper.py (GH-31204)
In [Lib/test/support/import_helper.py](https://github.com/python/cpython/blob/master/Lib/test/support/import_helper.py), the function `make_legacy_pyc` makes a call to `os.rename` which can fail when the source and target live on different devices. This happens (for example) when `PYTHONPYCACHEPREFIX` is set to a directory anywhere on disk, while a ramdisk is mounted on `/tmp` (the latter of which is the default on various Linux distros). Replacing `os.rename` with `shutil.move` fixes this.

skip_if_buggy_ucrt_strfptime() of test.support now uses
locale.getpreferredencoding(False) instead of
locale.getdefaultlocale() to get the Windows code page.

It was added as part of #29222 to avoid running freeze tool tests on the
buildbots but the logic was wrong so it did not skip tests on typical posix
setup buildbots where the worker is launched from cron via an @reboot task and
thus have no USER environment variable. This uses the canonical
`getpass.getuser()` API rather than rolling its own attempt.

Ensure that directory file descriptors refer to directories different
from the current directory, and that src_dir_fd and dst_dir_fd refer
to different directories.
Add context manager open_dir_fd() in test.support.os_helper.
