| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * gh-109974: Fix threading lock_tests race conditions (#110057) Fix race conditions in test_threading lock tests. Wait until a condition is met rather than using time.sleep() with a hardcoded number of seconds. * Replace sleeping loops with support.sleeping_retry() which raises an exception on timeout. * Add wait_threads_blocked(nthread) which computes a sleep depending on the number of threads. Remove _wait() function. * test_set_and_clear(): use a way longer Event.wait() timeout. * BarrierTests.test_repr(): wait until the 2 threads are waiting for the barrier. Use a way longer timeout for Barrier.wait() timeout. * test_thread_leak() no longer needs to count len(threading.enumerate()): Bunch uses threading_helper.wait_threads_exit() internally which does it in wait_for_finished(). * Add BaseLockTests.wait_phase() which implements a timeout. test_reacquire() and test_recursion_count() use wait_phase(). (cherry picked from commit 4e356ad183eeb567783f4a87fd092573da1e9252) * gh-109974: Fix more threading lock_tests race conditions (#110089) * Add context manager on Bunch class. * Bunch now catchs exceptions on executed functions and re-raise them at __exit__() as an ExceptionGroup. * Rewrite BarrierProxy.test_default_timeout(). Use a single thread. Only check that barrier.wait() blocks for at least default timeout seconds. * test_with(): inline _with() function.

* gh-97669: Fix test_tools reference leak (#98216)Victor Stinner2022-10-121-7/+1
| | | | | | | | test_tools.test_sundry() now uses an unittest mock to prevent the logging module to register a real "atfork" function which kept the logging module dictionary alive. So the logging module can be properly unloaded. Previously, the logging module was loaded before test_sundry(), but it's no longer the case since recent test_tools sub-tests removals.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | warnings.warn_explicit() (GH-97803) In `_warnings.c`, in the C equivalent of `warnings.warn_explicit()`, if the module globals are given (and not None), the warning will attempt to get the source line for the issued warning. To do this, it needs the module's loader. Previously, it would only look up `__loader__` in the module globals. In https://github.com/python/cpython/issues/86298 we want to defer to the `__spec__.loader` if available. The first step on this journey is to check that `loader == __spec__.loader` and issue another warning if it is not. This commit does that. Since this is a PoC, only manual testing for now. ```python # /tmp/foo.py import warnings import bar warnings.warn_explicit( 'warning!', RuntimeWarning, 'bar.py', 2, module='bar knee', module_globals=bar.__dict__, ) ``` ```python # /tmp/bar.py import sys import os import pathlib # __loader__ = pathlib.Path() ``` Then running this: `./python.exe -Wdefault /tmp/foo.py` Produces: ``` bar.py:2: RuntimeWarning: warning! import os ``` Uncomment the `__loader__ = ` line in `bar.py` and try it again: ``` sys:1: ImportWarning: Module bar; __loader__ != __spec__.loader (<_frozen_importlib_external.SourceFileLoader object at 0x109f7dfa0> != PosixPath('.')) bar.py:2: RuntimeWarning: warning! import os ``` Automerge-Triggered-By: GH:warsaw
