* Move get_signal_name() from test.libregrtest to test.support.
* Use get_signal_name() in support.script_helper.
* support.script_helper now decodes stdout and stderr from UTF-8,
instead of ASCII, if a command failed.
When creating the JUnit XML file, regrtest now escapes characters
which are invalid in XML, such as the chr(27) control character used
in ANSI escape sequences.
Test case matching patterns specified by options --match, --ignore,
--matchfile and --ignorefile are now tested in the order of
specification, and the last match determines whether the test case be run
or ignored.
* _add_python_opts() now handles cross compilation and HOSTRUNNER.
* display_header() now tells if Python is cross-compiled, display
HOSTRUNNER, and get the host platform.
* Remove Tools/scripts/run_tests.py script.
* Remove "make hostrunnertest": use "make buildbottest"
or "make test" instead.
Rename WORKER_ERROR to WORKER_BUG. Add WORKER_FAILED state: it does
not stop the manager, whereas WORKER_BUG does.
Change also TestResults.display_result() order: display failed tests
at the end, the important important information.
WorkerThread now tries to get the signal name for negative exit code.
In the subprocess code path, wait until the child process completes
with a timeout of EXIT_TIMEOUT seconds.
Fix create_worker_process() regression: use start_new_session=True if
USE_PROCESS_GROUP is true.
WorkerThread.wait_stopped() uses a timeout of 60 seconds, instead of
30 seconds.
Fix the test when run on an installed Python: use "abs_srcdir" of
sysconfig, and skip the test if the Python source code cannot be
found.
* Tools/patchcheck/patchcheck.py, Tools/freeze/test/freeze.py and
Lib/test/libregrtest/utils.py now first try to get "abs_srcdir"
from sysconfig, before getting "srcdir" from sysconfig.
* test.pythoninfo logs sysconfig "abs_srcdir".
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.
Remove replace_stdout(): call sys.stdout.reconfigure() instead of set
the error handler to backslashreplace.
display_header() logs an empty line and flush stdout.
Remove encoding workaround in display_header() since stdout error
handler is now set to backslashreplace earlier.
* Add --fast-ci and --slow-ci options to libregrtest:
* --fast-ci uses a default timeout of 10 minutes and "-u all,-cpu"
(skip slowest tests).
* --slow-ci uses a default timeout of 20 minues and "-u all" (run
all tests).
* regrtest header now lists test resources.
* Makefile changes:
* "make test", "make hostrunnertest" and "make coverage-report" now
use --fast-ci option and TESTTIMEOUT variable.
* "make buildbottest" now uses "--slow-ci". Remove options which
became redundant with "--slow-ci".
* "make testall" and "make testuniversal" now use --slow-ci option
and TESTTIMEOUT variable.
* "make testall" now uses "find -exec rm ..." instead of
"find ... -print|xargs rm ...", same as "make clean".
* GitHub Actions workflow:
* Ubuntu and Address Sanitizer jobs now use "make test". Remove
options which became redundant with "--fast-ci".
* Windows jobs now use --fast-ci option.
* Use -j0 to detect the number of CPUs.
* Set Makefile TESTTIMEOUT default to an empty string, since
--slow-ci and --fast-ci use different default timeout. It's now
accepted to pass "--timeout=" to regrtest: treated as not timeout.
* Tools/scripts/run_tests.py now uses --fast-ci option.
* Tools/buildbot/test.bat now uses --slow-ci option. Remove
--timeout=1200 option, redundant with --slow-ci.
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.
On WASI platform, get_temp_dir() should behave differently since the
parent process is a WASI process and uses a different get_temp_dir()
path.
Fix also WorkerThread._runtest(): don't read JSON file if the worker
process exit code is non-zero.
On Emscripten and WASI platforms, or if --python command line option
is used, libregrtest now uses a filename for the JSON file.
Emscripten and WASI buildbot workers run the main test process with a
different Python (Linux) which spawns Emscripten/WASI processes using
the command specified in --python command line option. Passing a file
descriptor from the parent process to the child process doesn't work
in this case.
* Add JsonFile and JsonFileType classes
* Add RunTests.json_file_use_filename() method.
* Add a test in test_regrtest on the --python command line option.
* test_regrtest: add parallel=False parameter.
* Split long RunWorkers._runtest() function into sub-functions.
Fix Emscripten and WASI: start the test worker process in the Python
source code directory, where 'python.js' and 'python.wasm' can be
found. Then worker_process() changes to a temporary directory created
to run tests.
* create_worker_process() uses os_helper.SAVEDCWD as cwd.
* worker_process() uses get_temp_dir() as the parent directory for
get_work_dir().
* Don't use plural but singual for "test" in "Run 1 test ..."
message.
* Remove unused imports.
* Add WORK_DIR_PREFIX and WORKER_WORK_DIR_PREFIX constants.
Don't spawn more threads than the number of jobs: these worker
threads would never get anything to do.
* Add the number of tests in "Run ... tests in ..." message.
* Add RunTests.get_jobs() method.
* Add plural() function.
* count() uses f-string.
* Rename runtest_mp.py to run_workers.py
* Move exit_timeout() and temp_cwd() context managers from
Regrtest.main() to Regrtest.run_tests(). Actions like --list-tests
or --list-cases don't need these protections.
* Regrtest: remove selected and tests attributes. Pass 'selected' to
list_tests(), list_cases() and run_tests(). display_result() now
expects a TestTuple, instead of TestList.
* Rename setup_tests() to setup_process() and rename setup_support()
to setup_tests().
* Move _adjust_resource_limits() to utils and rename it to
adjust_rlimit_nofile().
* Move replace_stdout() to utils.
* Fix RunTests.verbose type: it's an int.
* Add single.py and result.py files.
* Rename runtest.py to runtests.py.
* Move run_single_test() function and its helper functions to
single.py.
* Move remove_testfn(), abs_module_name() and normalize_test_name()
to utils.py.
* Move setup_support() to setup.py.
* Move type hints like TestName to utils.py.
* Rename runtest.py to runtests.py.
Add new worker.py file:
* Move create_worker_process() and worker_process() to this file.
* Add main() function to worker.py. create_worker_process() now
runs the command: "python -m test.libregrtest.worker JSON".
* create_worker_process() now starts the worker process in the
current working directory. Regrtest now gets the absolute path of
the reflog.txt filename: -R command line option filename.
* Remove --worker-json command line option.
Remove test_regrtest.test_worker_json().
Related changes:
* Add write_json() and from_json() methods to TestResult.
* Rename select_temp_dir() to get_temp_dir() and move it to utils.
* Rename make_temp_dir() to get_work_dir() and move it to utils.
It no longer calls os.makedirs(): Regrtest.main() now calls it.
* Move fix_umask() to utils. The function is now called by
setup_tests().
* Move StrPath to utils.
* Add exit_timeout() context manager to utils.
* RunTests: Replace junit_filename (StrPath) with use_junit (bool).
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.
Remove the distutils package. It was deprecated in Python 3.10 by PEP
632 "Deprecate distutils module". For projects still using distutils
and cannot be updated to something else, the setuptools project can
be installed: it still provides distutils.
* Remove Lib/distutils/ directory
* Remove test_distutils
* Remove references to distutils
* Skip test_check_c_globals and test_peg_generator since they use
distutils
support.print_warning() now stores the original value of
sys.__stderr__ and uses it to log warnings. libregrtest uses the same
stream to log unraisable exceptions and uncaught threading
exceptions.
Partially revert commit dbe213de7ef28712bbfdb9d94a33abb9c33ef0c2:
libregrtest no longer replaces sys.__stdout__, sys.__stderr__, and
stdout and stderr file descriptors.
Remove also a few unused imports in libregrtest.
libregrtest -W/--verbose3 now also replace sys.__stdout__,
sys.__stderr__, and stdout and stderr file descriptors (fd 1 and fd
2).
support.print_warning() messages are now logged in the expected
order.
The "./python -m test test_eintr -W" command no longer logs into
stdout if the test pass.
libregrtest now clears the type cache later to reduce the risk of
false alarm when checking for reference leaks. Previously, the type
cache was cleared too early and libregrtest raised a false alarm
about reference leaks under very specific conditions.
Move also support.gc_collect() outside clear/cleanup functions to
make the garbage collection more explicit.

test.libregrtest now marks a test as ENV_CHANGED (altered the
execution environment) if a thread raises an exception but does not
catch it. It sets a hook on threading.excepthook. Use
--fail-env-changed option to mark the test as failed.
libregrtest regrtest_unraisable_hook() explicitly flushs
sys.stdout, sys.stderr and sys.__stderr__.
Move clear_caches() from libregrtest.refleak to libregrtest.utils to
avoid importing libregrtest.refleak when it's not needed.
clear_caches() now only calls re.purge() if 're' is in sys.modules.
