bpo-40275: Adding threading_helper submodule in test.support (GH-20263) 2020-05-28 00:10:27 +02:00
Victor Stinner 87255be696
bpo-40089: Add _at_fork_reinit() method to locks (GH-19195) 
Add a private _at_fork_reinit() method to _thread.Lock,
_thread.RLock, threading.RLock and threading.Condition classes:
reinitialize the lock after fork in the child process; reset the lock
to the unlocked state.

Rename also the private _reset_internal_locks() method of
threading.Event to _at_fork_reinit().

* Add _PyThread_at_fork_reinit() private function. It is excluded
  from the limited C API.
* threading.Thread._reset_internal_locks() now calls
  _at_fork_reinit() on self._tstate_lock rather than creating a new
  Python lock object.

bpo-15999: Clean up of handling boolean arguments. (GH-15610) 
* Use the 'p' format unit instead of manually called PyObject_IsTrue().
* Pass boolean value instead 0/1 integers to functions that needs boolean.
* Convert some arguments to boolean only once.

bpo-10978: Semaphores can release multiple threads at a time (GH-15588) 2019-08-29 01:45:19 -07:00

bpo-35513: Replace time.time() with time.monotonic() in tests (GH-11182) 
Replace time.time() with time.monotonic() in tests to measure time
delta.

test_zipfile64: display progress every minute (60 secs) rather than
every 5 minutes (5*60 seconds).

bpo-32692: Fix test_threading.test_set_and_clear() (GH-8331) 
Increase the timeout: give timeout x 4 instead of timeout x 2 to
threads to wait until the Event is set, but reduce the sleep from 500
ms to 250 ms. So the test should be more reliable and faster!

* add test for blocking

* Update threading.rst

* semaphore: remove documentation validation tests and move 'return value' test to BaseSemaphore

Victor Stinner ff40ecda73 bpo-31234: Add test.support.wait_threads_exit() (#3578) 
Use _thread.count() to wait until threads exit. The new context
manager prevents the "dangling thread" warning.

Victor Stinner 096ae3373a bpo-31234: Try to fix lock_tests warning (#3557) 
Try to fix the "Warning -- threading_cleanup() failed to cleanup 1
threads" warning in test.lock_tests: wait a little bit longer to give
time to the threads to complete.

Warning seen on test_thread and test_importlib.

Serhiy Storchaka 32cb968a2e bpo-30727: Fix a race condition in test_threading. (#2334) 2017-06-23 13:36:36 +03:00
Berker Peksag dd745cc3ff Issue #25551: Test condition behavior instead of its internals 
test_reset_internal_locks was looking at Event's _cond._lock. This
makes it harder to change internals of the Condition object and
makes the test fragile.

The test was added by Nir Soffer in 6108d30dde21.

Patch by Nir Soffer.

global import lock, eliminating well-known issues with threads and imports.

`threading.Semaphore` objects.  Original patch by Torsten Landschoff.
 2010-04-17 23:51:58 +00:00
Antoine Pitrou 7c3e577395 Issue #7316: the acquire() method of lock objects in the :mod:`threading` 
module now takes an optional timeout argument in seconds.  Timeout support
relies on the system threading library, so as to avoid a semi-busy wait
loop.
