* [3.12] gh-108834: Sync libregrtest with the main branch (#108966)Victor Stinner2023-09-081-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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 31c2945f143c6b80c837fcf09a5cfb85fea9ea4c) * 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 commit 1170d5a292b46f754cd29c245a040f1602f70301) * gh-108416: Mark slow but not CPU bound test methods with requires_resource('walltime') (GH-108480) (cherry picked from commit 1e0d62793a84001e92f1c80b511d3a212b435acc) * Manually sync Lib/test/libregrtest/ from main --------- Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* bpo-40003: test.bisect_cmd copies Python options (GH-19246)Victor Stinner2020-03-311-2/+14
| | | | | test.bisect_cmd now copies Python command line options like -O or -W. Moreover, emit a warning if test.bisect_cmd is used with -w/--verbose2 option.
* Change bisect to bisect_cmd in docstring (#13040)Xtreak2019-05-021-3/+3

* bpo-35519: Rename test.bisect to test.bisect_cmd (GH-11200)Victor Stinner2018-12-171-0/+167
Rename test.bisect module to test.bisect_cmd to avoid conflict with bisect module when running directly a test like "./python Lib/test/test_xmlrpc.py".
