* bpo-43843: libregrtest uses threading.excepthook (GH-25400)Victor Stinner2021-04-162-1/+36
| | | | | | | | | 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__.
* bpo-41718: libregrtest avoids importing datetime (GH-24985)Victor Stinner2021-03-231-3/+5
| | | | * libregrtest reimplements datetime.timedelta.__str__() * support.testresult only imports datetime if USE_XML is true.
* bpo-41718: Disable support.testresult XML output by default (GH-24982)Victor Stinner2021-03-231-0/+4
| | | | | | | RegressionTestResult.USE_XML must now be set to True to get the JUnit XML output. Reduce the number of imports when --junit-xml=FILE option is not used: 153 => 144 (-9).
* bpo-41718: libregrtest runtest avoids import_helper (GH-24983)Victor Stinner2021-03-231-2/+4
| | | | Inline import_helper.unload() in libregrtest.runtest to avoid one import.
* bpo-41718: Reduce libregrtest runtest imports (GH-24980)Victor Stinner2021-03-223-97/+107
| | | | | | 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.
* bpo-41718: regrtest saved_test_environment avoids imports (GH-24934)Victor Stinner2021-03-222-42/+69
| | | | | | | | | | | | | | | | | | | | | | | | | Reduce the number of modules imported by libregrtest. saved_test_environment no longer imports modules at startup, but try to get them from sys.modules. If an module is missing, skip the test. It also sets directly support.environment_altered. runtest() now now two saved_test_environment instances: one before importing the test module, one after importing it. Remove imports from test.libregrtest.save_env: * asyncio * logging * multiprocessing * shutil * sysconfig * urllib.request * warnings When a test method imports a module (ex: warnings) and the test has a side effect (ex: add a warnings filter), the side effect is not detected, because the module was not imported when Python enters the saved_test_environment context manager.

| | | | | | | | | | | | test_repl.test_close_stdin() now calls support.suppress_msvcrt_asserts() to fix the test on Windows. * Move suppress_msvcrt_asserts() from test.libregrtest.setup to test.support. Make its verbose parameter optional: verbose=False by default. * Add msvcrt.GetErrorMode(). * SuppressCrashReport now uses GetErrorMode() and SetErrorMode() of the msvcrt module, rather than using ctypes. * Remove also an unused variable (deadline) in wait_process().
* bpo-39983: Add test.support.print_warning() (GH-19683)Victor Stinner2020-04-232-2/+2
| | | | | | | Log "Warning -- ..." test warnings into sys.__stderr__ rather than sys.stderr, to ensure to display them even if sys.stderr is captured. test.libregrtest.utils.print_warning() now calls test.support.print_warning().

* bpo-37957: Allow regrtest to receive a file with test (and subtests) to ↵Pablo Galindo2019-11-193-3/+17
| | | | | | | 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-38614: Add timeout constants to test.support (GH-16964)Victor Stinner2019-10-301-0/+11
| | | | | | | | Add timeout constants to test.support: * LOOPBACK_TIMEOUT * INTERNET_TIMEOUT * SHORT_TIMEOUT * LONG_TIMEOUT
* bpo-38502: regrtest uses process groups if available (GH-16829)Victor Stinner2019-10-181-7/+22
| | | | | 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.
* bpo-37531: regrtest now catchs ProcessLookupError (GH-16827)Victor Stinner2019-10-161-0/+5
| | | | Fix a warning on a race condition on TestWorkerProcess.kill(): ignore silently ProcessLookupError rather than logging an useless warning.
* bpo-37531: regrtest ignores output on timeout (GH-16659)Victor Stinner2019-10-081-27/+37
| | | | | | | | | | | bpo-37531, bpo-38207: On timeout, regrtest no longer attempts to call `popen.communicate() again: it can hang until all child processes using stdout and stderr pipes completes. Kill the worker process and ignores its output. Reenable test_regrtest.test_multiprocessing_timeout(). bpo-37531: Change also the faulthandler timeout of the main process from 1 minute to 5 minutes, for Python slowest buildbots.
* bpo-36670: Enhance regrtest (GH-16556)Victor Stinner2019-10-034-50/+89
| | | | | | | | | | | | | | * Add log() method: add timestamp and load average prefixes to main messages. * WindowsLoadTracker: * LOAD_FACTOR_1 is now computed using SAMPLING_INTERVAL * Initialize the load to the arithmetic mean of the first 5 values of the Processor Queue Length value (so over 5 seconds), rather than 0.0. * Handle BrokenPipeError and when typeperf exit. * format_duration(1.5) now returns '1.5 sec', rather than '1 sec 500 ms'
* bpo-36670: Enhance regrtest WindowsLoadTracker (GH-16553)Victor Stinner2019-10-031-26/+42

* bpo-36670, regrtest: Fix WindowsLoadTracker() for partial line (GH-16550)Victor Stinner2019-10-021-1/+4

* bpo-36670: regrtest bug fixes (GH-16537)Victor Stinner2019-10-021-10/+12
| | | | | | | | * Fix TestWorkerProcess.__repr__(): start_time is only valid if _popen is not None. * Fix _kill(): don't set _killed to True if _popen is None. * _run_process(): only set _killed to False after calling run_test_in_subprocess().
* bpo-36670: Multiple regrtest bugfixes (GH-16511)Victor Stinner2019-10-013-133/+175
| | | | | | | | | | | | | | | | * Windows: Fix counter name in WindowsLoadTracker. Counter names are localized: use the registry to get the counter name. Original change written by Lorenz Mende. * Regrtest.main() now ensures that the Windows load tracker is also killed if an exception is raised * TestWorkerProcess now ensures that worker processes are no longer running before exiting: kill also worker processes when an exception is raised. * Enhance regrtest messages and warnings: include test name, duration, add a worker identifier, etc. * Rename MultiprocessRunner to TestWorkerProcess * Use print_warning() to display warnings.

* bpo-37531: regrtest main process uses shorter timeout (GH-16220)Victor Stinner2019-09-171-6/+6
| | | | | | When using multiprocesss (-jN), the main process now uses a timeout of 60 seconds instead of the double of the --timeout value. The buildbot server stops a job which does not produce any output in 1200 seconds.
* bpo-37936: Systematically distinguish rooted vs. unrooted in .gitignore ↵Greg Price2019-09-111-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-15823) A root cause of bpo-37936 is that it's easy to write a .gitignore rule that's intended to apply to a specific file (e.g., the `pyconfig.h` generated by `./configure`) but actually applies to all similarly-named files in the tree (e.g., `PC/pyconfig.h`.) Specifically, any rule with no non-trailing slashes is applied in an "unrooted" way, to files anywhere in the tree. This means that if we write the rules in the most obvious-looking way, then * for specific files we want to ignore that happen to be in subdirectories (like `Modules/config.c`), the rule will work as intended, staying "rooted" to the top of the tree; but * when a specific file we want to ignore happens to be at the root of the repo (like `platform`), then the obvious rule (`platform`) will apply much more broadly than intended: if someone tries to add a file or directory named `platform` somewhere else in the tree, it will unexpectedly get ignored. That's surprising behavior that can make the .gitignore file's behavior feel finicky and unpredictable. To avoid it, we can simply always give a rule "rooted" behavior when that's what's intended, by systematically using leading slashes. Further, to help make the pattern obvious when looking at the file and minimize any need for thinking about the syntax when adding new rules: separate the rules into one group for each type, with brief comments identifying them. For most of these rules it's clear whether they're meant to be rooted or unrooted, but in a handful of cases I've only guessed. In that case the safer default (the choice that won't hide information) is the narrower, rooted meaning, with a leading slash. If for some of these the unrooted meaning is desired after all, it'll be easy to move them to the unrooted section at the top.

* bpo-37707: Exclude expensive unit tests from PGO task (GH-15009)Neil Schemenauer2019-07-301-0/+1

* bpo-36044: Reduce number of unit tests run for PGO build (GH-14702)Neil Schemenauer2019-07-223-1/+61
| | | | | | | | | | | | Reduce the number of unit tests run for the PGO generation task. This speeds up the task by a factor of about 15x. Running the full unit test suite is slow. This change may result in a slightly less optimized build since not as many code branches will be executed. If you are willing to wait for the much slower build, the old behavior can be restored using './configure [..] PROFILE_TASK="-m test --pgo-extended"'. We make no guarantees as to which PGO task set produces a faster build. Users who care should run their own relevant benchmarks as results can depend on the environment, workload, and compiler tool chain.
* bpo-37473: Don't import importlib ASAP in tests (GH-14661)Victor Stinner2019-07-141-3/+0
| | | | | | | | | bpo-15386, bpo-37473: test_import, regrtest and libregrtest no longer import importlib as soon as possible, as the first import, "to test bpo-15386". It is tested by test_import.test_there_can_be_only_one(). Sort test_import imports.
* bpo-37421: urllib.request tests call urlcleanup() (GH-14529)Victor Stinner2019-07-021-0/+13
| | | | | | | | urllib.request tests now call urlcleanup() to remove temporary files created by urlretrieve() tests and to clear the _opener global variable set by urlopen() and functions calling indirectly urlopen(). regrtest now checks if urllib.request._url_tempfiles and urllib.request._opener are changed by tests.
* bpo-34602: Avoid failures setting macOS stack resource limit (GH-14546)Ned Deily2019-07-021-16/+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.
