Issue #26538: libregrtest: Fix setup_tests() to keep module.__path__ type
(_NamespacePath), don't convert to a list.
Add _NamespacePath.__setitem__() method to importlib._bootstrap_external.
* Fix accumulate_result(): don't use time on interrupted and failed test
* Add unit test for interrupted test
* Add unit test on --slow with interrupted test, with and without
multiprocessing
* Fix "-m test --forever": replace _test_forever() with self._test_forever()
* Add unit test for --forever
* Add unit test for a failing test
* Fix also some pyflakes warnings in libregrtest
* Remove runtest_ns(): pass directly ns to runtest().
* Create also Regrtest.rerun_failed_tests() method.
* Inline again Regrtest.run_test(): it's no more justified to have a method
Slaves (child processes running tests for regrtest -jN) now inherit
--memlimit/-M, --threshold/-t and --nowindows/-n options.
* -M, -t and -n are now supported with -jN
* Factorize code to run tests.
* run_test_in_subprocess() now pass the whole "ns" namespace to the child
process.
Running the Python test suite with -jN now:
- Display the duration of tests which took longer than 30 seconds
- Display the tests currently running since at least 30 seconds
- Display the tests we are waiting for when the test suite is interrupted
Clenaup also run_test_in_subprocess() code.
Python doesn't display the refcount anymore by default. It only displays it
when -X showrefcount command line option is used, which is not the case here.
regrtest can be run with -X showrefcount, the option is not inherited by child
processes.
Move the code to run tests in multiple processes using threading and subprocess
to a new submodule.
Move also slave_runner() (renamed to run_tests_slave()) and
run_test_in_subprocess() (renamed to run_tests_in_subprocess()) there.
with attributes and methods.
The --threshold command line option is now ignored if the gc module is missing.
* Convert main() variables to Regrtest attributes, document some attributes
* Convert accumulate_result() function to a method
* Create setup_python() function and setup_regrtest() method.
* Import gc at top level
* Move resource.setrlimit() and the code to make the module paths absolute into
the new setup_python() function. So this code is no more executed when the
module is imported, only when main() is executed. We have a better control on
when the setup is done.
* Move textwrap import from printlist() to the top level.
* Some other minor cleanup.
Start to split regrtest.py into smaller parts with the creation of
Lib/test/libregrtest/cmdline.py: code to handle the command line, especially
parsing command line arguments. This part of the code is tested by
test_regrtest.
