* Close explicitly queues to make sure that we don't leave dangling
threads
* test_queue_in_process(): remove unused queue
* test_access() joins also the process to fix a random warning
bpo-26762: test_multiprocessing now detects dangling processes and
threads per test case classes:
* setUpClass()/tearDownClass() of mixin classes now check if
multiprocessing.process._dangling or threading._dangling was
modified to detect "dangling" processses and threads.
* ManagerMixin.tearDownClass() now also emits a warning if it still
has more than one active child process after 5 seconds.
* tearDownModule() now checks for dangling processes and threads
before sleep 500 ms. And it now only sleeps if there is a least one
dangling process or thread.
bpo-26762: Fix more dangling processes and threads in
test_multiprocessing:
* Queue: call close() followed by join_thread()
* Process: call join() or self.addCleanup(p.join)
* bpo-30980: Fix close test to fail
test_close_twice was not considering the fact that file_wrapper is
duping the file descriptor. Closing the original descriptor left the
duped one open, hiding the fact that close protection is not effective.
* bpo-30980: Fix double close protection
Invalidated self.fd before closing, handling correctly the case when
os.close raises.
* bpo-30980: Fix fd leak introduced in the fixed test
test_level() of _test_multiprocessing._TestLogging now uses regular
processes rather than daemon processes to prevent zombi processes
(to not "leak" processes).
In configdialog: Document causal pathways in create_font_tab docstring. Simplify some attribute names. Move set_samples calls to var_changed_font (idea from Cheryl Sabella). Move related functions to positions after the create widgets function.
In test_configdialog: Fix test_font_set so not order dependent. Fix renamed test_indent_scale so it tests the widget. Adjust tests for movement of set_samples call. Add tests for load functions. Put all font tests in one class and tab indent tests in another. Except for two lines, these tests completely cover the related functions.
* Document causal event pathways in docstring.
* Simplify some attribute names.
* Rename test_bold_toggle_set_samples to make test_font_set fail.
* Fix test_font_set so not order dependent.
* Fix renamed test_indent_scale so it tests the widget.
* 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
Use sys.modules.get() in the "with _ModuleLockManager(name):" block
to protect the dictionary key with the module lock and use an atomic
get to prevent race condition.
Remove also _bootstrap._POPULATE since it was unused
(_bootstrap_external now has its own _POPULATE object), add a new
_SENTINEL object instead.
* bpo-19896: Add typcodes 'q' and 'Q' to multiprocessing.sharedctypes. Patch by Antony Lee.
* Add NEWS entry.
* Slightly tweak NEWS entry
Make it clear this is more of a fix rather than a new feature.
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.
Cython will, in the right circumstances, offer a MethodType instance
where im_func is a builtin function. Any instance of MethodType is
automatically assumed to be a Python-defined function (more
specifically, a function that has an inspectable signature), but
_set_signature was still conservative in its assumptions. As a result
_set_signature would return early with None instead of a mock since
the im_func had no inspectable signature. This causes problems
deeper inside mock, as _set_signature is assumed to _always_
return a mock, and nothing checked its return value.
In similar corner cases, autospec will simply not check the spec of the
function, so _set_signature is amended to now return early with the
original, not-wrapped mock object.
Patch by Aaron Gallagher.
* bpo-30794: added kill() method to multiprocessing.Process
* Added entries to documentation and NEWS
* Refactored test_terminate and test_kill
* Fix SIGTERM and SIGKILL being used on Windows for the tests
* Added "versionadded" marker to the documentation
* Fix trailing whitespace in doc
* Add section to idlelib/idle-test/README.txt.
* Include check that branches are taken both ways.
* Exclude IDLE-specific code that does not run during unit tests.
AIX uses iso8859-1 in the C locale, not ASCII
AIX doesn't currently provide any of the locale
coercion locales, but we leave locale coercion
enabled in case one gets added in the future.
Changed "subbset" to "subset". Also made the sentences read like things were happening instead of stating what the code should do (in other words more descriptive than prescriptive).
tearDown() now clears explicitly the self.server variable to make
sure that the thread is completely cleared when tearDownClass()
checks if all threads have been cleaned up.
Fix the following warning:
$ ./python -m test --fail-env-changed -m test.test_os.TestSendfile.test_keywords -R 3:1 test_os
(...)
Warning -- threading_cleanup() failed to cleanup 0 threads after 3 sec (count: 0, dangling: 2)
(...)
Tests result: ENV CHANGED
* Rewrite importlib _get_module_lock(): it is now responsible to hold
the imp lock directly.
* _find_and_load() now holds the module lock to check if name is in
sys.modules to prevent a race condition
multiprocessing.Queue.join_thread() now waits until the thread
completes, even if the thread was started by the same process which
created the queue.
Fix the following warning which occurs randomly when running
test_handle_called_with_mp_queue of test_logging.QueueListenerTest:
Warning -- threading_cleanup() failed to cleanup -1 threads after 4 sec (count: 0, dangling: 1)
Turns out that history-size was added in readline 6.0. This explain why
this tests fail on FreeBSD when using readline 5.2. We skip now the
history size if readline does not support it.
See https://cnswww.cns.cwru.edu/php/chet/readline/CHANGES for
details.
* In config, put dump test code in a function; run it and unittest in 'if __name__ == '__main__'.
* Add class config.ConfigChanges based on changes_class_v4.py on bpo issue.
* Add class test_config.ChangesTest, partly based on configdialog_tests_v1.py on bpo issue.
* Revise configdialog to use ConfigChanges, mostly as specified in tracker msg297804.
* Revise test_configdialog to match configdialog changes. All tests pass in both files.
* Remove configdialog functions unused or moved to ConfigChanges.
