* 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 commit31c2945f14) * gh-108834: regrtest --fail-rerun exits with code 5 (#108896) When the --fail-rerun option is used and a test fails and then pass, regrtest now uses exit code 5 ("rerun) instead of 2 ("bad test"). (cherry picked from commit1170d5a292) * gh-108416: Mark slow but not CPU bound test methods with requires_resource('walltime') (GH-108480) (cherry picked from commit1e0d62793a) * Manually sync Lib/test/libregrtest/ from main --------- Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
