(cherry picked from commit 2ea71a07d0a720707094ee55f78fd232c40724bc) * [3.8] Update libregrtest from master (GH-19516) * bpo-37531: regrtest now catchs ProcessLookupError (GH-16827) Fix a warning on a race condition on TestWorkerProcess.kill(): ignore silently ProcessLookupError rather than logging an useless warning. (cherry picked from commit a661392f8fb5ac4fc095aa1845d1eb7a25c4e9be) * bpo-38502: regrtest uses process groups if available (GH-16829) test.regrtest now uses process groups in the multiprocessing mode (-jN command line option) if process groups are available: if os.setsid() and os.killpg() functions are available. (cherry picked from commit ecb035cd14c11521276343397151929a94018a22) * bpo-37957: Allow regrtest to receive a file with test (and subtests) to ignore (GH-16989) When building Python in some uncommon platforms there are some known tests that will fail. Right now, the test suite has the ability to ignore entire tests using the -x option and to receive a filter file using the --matchfile filter. The problem with the --matchfile option is that it receives a file with patterns to accept and when you want to ignore a couple of tests and subtests, is too cumbersome to lists ALL tests that are not the ones that you want to accept and he problem with -x is that is not easy to ignore just a subtests that fail and the whole test needs to be ignored. For these reasons, add a new option to allow to ignore a list of test and subtests for these situations.

* bpo-34602: Avoid failures setting macOS stack resource limit (GH-14546)Miss Islington (bot)2019-07-021-16/+0
| | | | | | | | | | | | | | | | | | | | Under some conditions the earlier fix for bpo-18075, "Infinite recursion tests triggering a segfault on Mac OS X", now causes failures on macOS when attempting to change stack limit with resource.setrlimit resource.RLIMIT_STACK, like regrtest does when running the test suite. The reverted change had specified a non-default stack size when linking the python executable on macOS. As of macOS 10.14.4, the previous code causes a hard failure when running tests, although similar failures had been seen under some conditions under some earlier systems. Reverting the change to the interpreter stack size at link time helped for release builds but caused some tests to fail when built --with-pydebug. Try the opposite approach: continue to build the interpreter with an increased stack size on macOS and remove the failing setrlimit call in regrtest initialization. This will definitely avoid the resource.RLIMIT_STACK error and should have no, or fewer, side effects.

| | | | | | | | | | | | When using multiprocessing (-jN option), worker processes now create their temporary directory inside the temporary directory of the main process. So the main process is able to remove temporary directories of worker processes even if they crash or when they are killed by regrtest on KeyboardInterrupt (CTRL+c). Rework also how multiprocessing arguments are parsed in main.py. (cherry picked from commit 3c93153f7db5dd9b06f229e61978fd9199b3c097) Co-authored-by: Victor Stinner <vstinner@redhat.com>

(cherry picked from commit 75120d2205af086140e5e4e2dc620eb19cdf9078) * bpo-34060: Report system load when running test suite for Windows (GH-8357) While Windows exposes the system processor queue length, the raw value used for load calculations on Unix systems, it does not provide an API to access the averaged value. Hence to calculate the load we must track and average it ourselves. We can't use multiprocessing or a thread to read it in the background while the tests run since using those would conflict with test_multiprocessing and test_xxsubprocess. Thus, we use Window's asynchronous IO API to run the tracker in the background with it sampling at the correct rate. When we wish to access the load we check to see if there's new data on the stream, if there is, we update our load values.

* bpo-31217: Fix regrtest -R for small integer (#3260)Victor Stinner2017-09-011-3/+11
| | | | | | | | Use a pool of integer objects toprevent false alarm when checking for memory block leaks. Fill the pool with values in -1000..1000 which are the most common (reference, memory block, file descriptor) differences. Co-Authored-By: Antoine Pitrou <pitrou@free.fr>
* bpo-30871: Add test.pythoninfo (#3075)Victor Stinner2017-08-171-3/+0
| | | | | | * Add Lib/test/pythoninfo.py: script collecting various informations about Python to help debugging test failures. * regrtest: remove sys.hash_info and sys.flags from header. * Travis CI, Appveyor: run pythoninfo before tests
* regrtest: count also env changed as failures in progress (#3061)Victor Stinner2017-08-101-2/+3

* bpo-31160: regrtest now reaps child processes (#3044)Victor Stinner2017-08-091-0/+5
| | | | Add a post_test_cleanup() function which currently only calls support.reap_children().

| | | | | | | | | | method (#2813) * bpo-26732: fix too many fds in processes started with the "forkserver" method A child process would inherit as many fds as the number of still-running children. * Add blurb and test comment
* bpo-30822: Exclude tzdata from regrtest --all (#2775)Victor Stinner2017-07-202-4/+13
| | | | | | | | | | | | | When running the test suite using --use=all / -u all, exclude tzdata since it makes test_datetime too slow (15-20 min on some buildbots) which then times out on some buildbots. -u tzdata must now be enabled explicitly, -u tzdata or -u all,tzdata, to run all test_datetime tests. Fix also regrtest command line parser to allow passing -u extralargefile to run test_zipfile64. Travis CI: remove -tzdata. Replace -u all,-tzdata,-cpu with -u all,-cpu since tzdata is now excluded from -u all.
* bpo-30764: Fix regrtest --fail-env-changed --forever (#2536)Victor Stinner2017-07-031-1/+3
| | | --forever now stops if a fail changes the environment.
* threading_cleanup() failure marks test as ENV_CHANGED (#2500)Victor Stinner2017-06-302-1/+10
| | | | | | | If threading_cleanup() fails to cleanup threads, set a a new support.environment_altered flag to true, flag uses by save_env which is used by regrtest to check if a test altered the environment. At the end, the test file fails with ENV_CHANGED instead of SUCCESS, to report that it altered the environment.
* bpo-30776: regrtest: reduce memleak false positive (#2484)Victor Stinner2017-06-291-10/+3
| | | Only report a leak if each run leaks at least one memory block.
* bpo-30776: reduce regrtest -R false positives (#2422)Victor Stinner2017-06-271-3/+22
| | | | | | | | | | | | | | * Change the regrtest --huntrleaks checker to decide if a test file leaks or not. Require that each run leaks at least 1 reference. * Warmup runs are now completely ignored: ignored in the checker test and not used anymore to compute the sum. * Add an unit test for a reference leak. Example of reference differences previously considered a failure (leak) and now considered as success (success, no leak): [3, 0, 0] [0, 1, 0] [8, -8, 1]
* bpo-30764: regrtest: add --fail-env-changed option (#2402)Victor Stinner2017-06-262-1/+12
| | | | | | | | | | | | * bpo-30764: regrtest: change exit code on failure * Exit code 2 if failed tests ("bad") * Exit code 3 if interrupted * bpo-30764: regrtest: add --fail-env-changed option If the option is set, mark a test as failed if it alters the environment, for example if it creates a file without removing it.
* bpo-30523: regrtest --list-cases --match (#2401)Victor Stinner2017-06-261-1/+5
| | | | | | | * regrtest --list-cases now supports --match and --match-file options. Example: ./python -m test --list-cases -m FileTests test_os * --list-cases now also sets support.verbose to False to prevent messages to stdout when loading test modules. * Add support._match_test() private function.
* bpo-30523: regrtest: Add --list-cases option (#2238)mlouielu2017-06-163-8/+44
| | | | | | | | | | | * bpo-30523: regrtest: Add --list-cases option * bpo-30523: Enhance --list-cases * Add get_abs_module() function, use it in list_cases() * list_cases() now logs skipped tests into stderr * Remove unused doctest
* bpo-30284: Fix regrtest for out of tree build (#1481)Victor Stinner2017-06-141-1/+7
| | | | | | | | Use a build/ directory in the build directory, not in the source directory, since the source directory may be read-only and must not be modified. Fallback on the source directory if the build directory is not available (missing "abs_builddir" sysconfig variable).
