* test.bisect_cmd now exit with code 0 on success, and code 1 on
failure. Before, it was the opposite.
* test.bisect_cmd now runs the test worker process with
-X faulthandler.
* regrtest RunTests: Add create_python_cmd() and bisect_cmd()
methods.
Now all results from worker processes are aggregated and
displayed together as a summary at the end of a regrtest run.
The traditional trace is left in place for use with sequential
in-process test runs but now raises a warning that those
numbers are not precise.
`-T -j` requires `--with-pydebug` as it relies on `-Xpresite=`.
Test case matching patterns specified by options --match, --ignore,
--matchfile and --ignorefile are now tested in the order of
specification, and the last match determines whether the test case be run
or ignored.
In the subprocess code path, wait until the child process completes
with a timeout of EXIT_TIMEOUT seconds.
Fix create_worker_process() regression: use start_new_session=True if
USE_PROCESS_GROUP is true.
WorkerThread.wait_stopped() uses a timeout of 60 seconds, instead of
30 seconds.
WASM and WASI buildbots use multiple PYTHON environment variables
such as PYTHONPATH and _PYTHON_HOSTRUNNER. Don't use -E if the
--python=COMMAND option is used.
On Emscripten and WASI, or if --python command line is used,
libregrtest now writes JSON into stdout, instead of using a name
file.
* Add JsonFileType.STDOUT.
* Remove JsonFileType.FILENAME.
* test.pythoninfo logs environment variables related to
cross-compilation and running Python on Emscripten/WASI.
On Emscripten and WASI platforms, or if --python command line option
is used, libregrtest now uses a filename for the JSON file.
Emscripten and WASI buildbot workers run the main test process with a
different Python (Linux) which spawns Emscripten/WASI processes using
the command specified in --python command line option. Passing a file
descriptor from the parent process to the child process doesn't work
in this case.
* Add JsonFile and JsonFileType classes
* Add RunTests.json_file_use_filename() method.
* Add a test in test_regrtest on the --python command line option.
* test_regrtest: add parallel=False parameter.
* Split long RunWorkers._runtest() function into sub-functions.
Fix Emscripten and WASI: start the test worker process in the Python
source code directory, where 'python.js' and 'python.wasm' can be
found. Then worker_process() changes to a temporary directory created
to run tests.
* create_worker_process() uses os_helper.SAVEDCWD as cwd.
* worker_process() uses get_temp_dir() as the parent directory for
get_work_dir().
* Don't use plural but singual for "test" in "Run 1 test ..."
message.
* Remove unused imports.
* Add WORK_DIR_PREFIX and WORKER_WORK_DIR_PREFIX constants.
libregrtest now uses a separated file descriptor to write test result
as JSON. Previously, if a test wrote debug messages late around the
JSON, the main test process failed to parse JSON.
Rename TestResult.write_json() to TestResult.write_json_into().
worker_process() no longer writes an empty line at the end. There is
no need to separate test process output from the JSON output anymore,
since JSON is now written into a separated file descriptor.
create_worker_process() now always spawn the process with
close_fds=True.
* Rename runtest_mp.py to run_workers.py
* Move exit_timeout() and temp_cwd() context managers from
Regrtest.main() to Regrtest.run_tests(). Actions like --list-tests
or --list-cases don't need these protections.
* Regrtest: remove selected and tests attributes. Pass 'selected' to
list_tests(), list_cases() and run_tests(). display_result() now
expects a TestTuple, instead of TestList.
* Rename setup_tests() to setup_process() and rename setup_support()
to setup_tests().
* Move _adjust_resource_limits() to utils and rename it to
adjust_rlimit_nofile().
* Move replace_stdout() to utils.
* Fix RunTests.verbose type: it's an int.
* Add single.py and result.py files.
* Rename runtest.py to runtests.py.
* Move run_single_test() function and its helper functions to
single.py.
* Move remove_testfn(), abs_module_name() and normalize_test_name()
to utils.py.
* Move setup_support() to setup.py.
* Move type hints like TestName to utils.py.
* Rename runtest.py to runtests.py.
Add new worker.py file:
* Move create_worker_process() and worker_process() to this file.
* Add main() function to worker.py. create_worker_process() now
runs the command: "python -m test.libregrtest.worker JSON".
* create_worker_process() now starts the worker process in the
current working directory. Regrtest now gets the absolute path of
the reflog.txt filename: -R command line option filename.
* Remove --worker-json command line option.
Remove test_regrtest.test_worker_json().
Related changes:
* Add write_json() and from_json() methods to TestResult.
* Rename select_temp_dir() to get_temp_dir() and move it to utils.
* Rename make_temp_dir() to get_work_dir() and move it to utils.
It no longer calls os.makedirs(): Regrtest.main() now calls it.
* Move fix_umask() to utils. The function is now called by
setup_tests().
* Move StrPath to utils.
* Add exit_timeout() context manager to utils.
* RunTests: Replace junit_filename (StrPath) with use_junit (bool).
