* gh-92584: Remove the distutils package (#99061)Victor Stinner2022-11-031-9/+0
| | | | | | | | | | | | 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
* GH-98686: Quicken everything (GH-98687)Brandt Bucher2022-11-021-2/+1

* gh-98903: Test suite fails with exit code 4 if no tests ran (#98904)Victor Stinner2022-11-021-6/+16
| | | | | | | The Python test suite now fails wit exit code 4 if no tests ran. It should help detecting typos in test names and test methods. * Add "EXITCODE_" constants to Lib/test/libregrtest/main.py. * Fix a typo: "NO TEST RUN" becomes "NO TESTS RAN"
* gh-95027: Fix regrtest stdout encoding on Windows (#98492)Victor Stinner2022-10-211-3/+11
| | | | | | On Windows, when the Python test suite is run with the -jN option, the ANSI code page is now used as the encoding for the stdout temporary file, rather than using UTF-8 which can lead to decoding errors.
* gh-96465: Clear fractions hash lru_cache under refleak testing (GH-96689)Zachary Ware2022-09-081-0/+7
| | | Automerge-Triggered-By: GH:zware
* gh-94026: Buffer regrtest worker stdout in temporary file (GH-94253)Christian Heimes2022-06-291-39/+38

* Run Tools/scripts/reindent.py (#94225)Victor Stinner2022-06-261-1/+0
| | | | | Reindent files which were not properly formatted (PEP 8: 4 spaces). Remove also some trailing spaces.
* gh-94052: Don't re-run failed tests with --python option (#94054)Christian Heimes2022-06-213-6/+17

* gh-84461: Fix Emscripten umask and permission issues (GH-94002)Christian Heimes2022-06-191-0/+12
| | | | | | | | - Emscripten's default umask is too strict, see https://github.com/emscripten-core/emscripten/issues/17269 - getuid/getgid and geteuid/getegid are stubs that always return 0 (root). Disable effective uid/gid syscalls and fix tests that use chmod() current user. - Cannot drop X bit from directory.
* gh-93353: regrtest supports checking tmp files with -j2 (#93909)Victor Stinner2022-06-161-3/+6
| | | | | regrtest now also implements checking for leaked temporary files and directories when using -jN for N >= 2. Use tempfile.mkdtemp() to create the temporary directory. Skip this check on WASI.
* gh-93353: Fix regrtest for -jN with N >= 2 (GH-93813)Victor Stinner2022-06-141-15/+21
|
* gh-93353: regrtest checks for leaked temporary files (#93776)Victor Stinner2022-06-142-7/+35
| | | | | When running tests with -jN, create a temporary directory per process and mark a test as "environment changed" if a test leaks a temporary file or directory.
* gh-84461: Fix parallel testing on WebAssembly (GH-93768)Christian Heimes2022-06-131-3/+8

* bpo-44336: Prevent tests hanging on child process handles on Windows (GH-26578)Jeremy Kloth2022-03-222-185/+117
| | | | | Replace the child process `typeperf.exe` with a daemon thread that reads the performance counters directly. This prevents the issues that arise from inherited handles in grandchild processes (see issue37531 for discussion). We only use the load tracker when running tests in multiprocess mode. This prevents inadvertent interactions with tests expecting a single threaded environment. Displaying load is really only helpful for buildbots running in multiprocess mode anyway.

* Revert "bpo-28533: Remove asyncore, asynchat, smtpd modules (GH-29521)" ↵Victor Stinner2021-12-071-1/+11
| | | | | (GH-29951) This reverts commit 9bf2cbc4c498812e14f20d86acb61c53928a5a57.
* bpo-28533: Remove asyncore, asynchat, smtpd modules (GH-29521)Victor Stinner2021-11-151-11/+1
| | | | | | | | | | | | | | | | Remove the asyncore and asynchat modules, deprecated in Python 3.6: use the asyncio module instead. Remove the smtpd module, deprecated in Python 3.6: the aiosmtpd module can be used instead, it is based on asyncio. * Remove asyncore, asynchat and smtpd documentation * Remove test_asyncore, test_asynchat and test_smtpd * Rename Lib/asynchat.py to Lib/test/support/_asynchat.py * Rename Lib/asyncore.py to Lib/test/support/_asyncore.py * Rename Lib/smtpd.py to Lib/test/support/_smtpd.py * Remove DeprecationWarning from private _asyncore, _asynchat and _smtpd modules * _smtpd: remove deprecated properties
* bpo-45745: Remove regrtest --findleaks options (GH-29514)Victor Stinner2021-11-123-10/+3
| | | | | Remove the --findleaks command line option of regrtest: use the --fail-env-changed option instead. Since Python 3.7, it was a deprecated alias to the --fail-env-changed option.
* bpo-10572: Fixup Lib/test/libregrtest/pgo.py (GH-29327)Erlend Egeberg Aasland2021-11-011-1/+1

* bpo-43592: Raise RLIMIT_NOFILE in test.libregrtest (GH-29127)Gregory P. Smith2021-10-221-0/+24
| | | | | | | Raise RLIMIT_NOFILE in test.libregrtest. On macOS the default is often too low for our testsuite to succeed. Co-authored by reviewer: Victor Stinner
* bpo-45410: regrtest replaces print_warning.orig_stderr (GH-28926)Victor Stinner2021-10-132-3/+13
| | | | | | When running Python tests with -W, runtest() now replaces support.print_warning.orig_stderr to preserve the messages order. Add an unit test.
* bpo-45410: regrtest -W leaves stdout/err FD unchanged (GH-28915)Victor Stinner2021-10-135-67/+12
| | | | | | | | | | | | 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.
* bpo-45410: Enhance libregrtest -W/--verbose3 option (GH-28908)Victor Stinner2021-10-122-14/+69
| | | | | | | | | | | 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.
* bpo-45410: Add test.support.flush_std_streams() (GH-28885)Victor Stinner2021-10-111-9/+2
| | | support.print_warning() now flushs sys.stdout.
* bpo-45410: libregrtest -jN writes stderr into stdout (GH-28819)Victor Stinner2021-10-081-22/+18
| | | | | | When libregrtest spawns a worker process, stderr is now written into stdout to keep messages order. Use a single pipe for stdout and stderr, rather than two pipes. Previously, messages were out of order which made analysis of buildbot logs harder
* Fix typos in the Lib directory (GH-28775)Christian Clauss2021-10-061-1/+1
| | | | | Fix typos in the Lib directory as identified by codespell. Co-authored-by: Terry Jan Reedy <tjreedy@udel.edu>
* bpo-45118: Fix regrtest second summary for re-run tests (GH-28183)Victor Stinner2021-09-071-4/+7
| | | | Fix regrtest second summary when using -w/--verbose2 command line option: lists re-run tests in the second test summary.
* bpo-44895: libregrtest: refleak check clears types later (GH-28113)Victor Stinner2021-09-013-14/+15
| | | | | | | | | | | 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. Co-authored-by: Irit Katriel <1055913+iritkatriel@users.noreply.github.com>
* bpo-44708: Only re-run test methods that match names of previously failing ↵Łukasz Langa2021-07-224-162/+312
| | | | | | | | | | | test methods (GH-27287) * Move to a static argparse.Namespace subclass * Roughly annotate runtest.py * Refactor libregrtest to use lossless test result objects * Only re-run test methods that match names of previously failing test methods * Adopt tests to cover test method name matching Co-authored-by: Pablo Galindo Salgado <Pablogsal@gmail.com>

* bpo-44187: Quickening infrastructure (GH-26264)Mark Shannon2021-06-071-2/+3
| | | | | | | | | | | | | | * Add co_firstinstr field to code object. * Implement barebones quickening. * Use non-quickened bytecode when tracing. * Add NEWS item * Add new file to Windows build. * Don't specialize instructions with EXTENDED_ARG.
* 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.
