| | | | | | | | | | | | sys.settrace calls threading.currentThread. The correction somewhat improves the code, but it was close. Many thanks to the "with" construct, which turns python code into C calls. I wonder if it is not better to sys.settrace(None) just after running the __main__ module and before finalization.

| | | | | | | up after it was joined had a traceback pointing to that thread's (deleted) target attribute, while the test was trying to check that the target was destroyed. Big thanks to Antoine Pitrou for diagnosing the race and pointing out sys.exc_clear() to kill the exception early. This fixes issue 2496.

| | | | | | | | | | | | | | | | | | | | | | new thread had started. At least on my MacBook Pro, that wound up sleeping for a full 10ms (probably 1 jiffy). By using an Event instead, we can be absolutely certain that the thread has started, and return more quickly (217us). Before: $ ./python.exe -m timeit -s 'from threading import Thread' 't = Thread(); t.start(); t.join()' 100 loops, best of 3: 10.3 msec per loop $ ./python.exe -m timeit -s 'from threading import Thread; t = Thread()' 't.isAlive()' 1000000 loops, best of 3: 0.47 usec per loop After: $ ./python.exe -m timeit -s 'from threading import Thread' 't = Thread(); t.start(); t.join()' 1000 loops, best of 3: 217 usec per loop $ ./python.exe -m timeit -s 'from threading import Thread; t = Thread()' 't.isAlive()' 1000000 loops, best of 3: 0.86 usec per loop To be fair, the 10ms isn't CPU time, and other threads including the spawned one get to run during it. There are also some slightly more complicated ways to get back the .4us in isAlive() if we want.
* Followup to r61011: Also avoid the reference cycle when the Thread's targetJeffrey Yasskin2008-02-231-5/+7

* Prevent classes like:Jeffrey Yasskin2008-02-231-0/+3
| | | | | | | | | | | | | | class RunSelfFunction(object): def __init__(self): self.thread = threading.Thread(target=self._run) self.thread.start() def _run(self): pass from creating a permanent cycle between the object and the thread by having the Thread delete its references to the object when it completes. As an example of the effect of this bug, paramiko.Transport inherits from Thread to avoid it.

| | | | | | | | | | | | | | | | 46640 Patch #1454481: Make thread stack size runtime tunable. 46647 Markup fix The first is causing many buildbots to fail test runs, and there are multiple causes with seemingly no immediate prospects for repairing them. See python-dev discussion. Note that a branch can (and should) be created for resolving these problems, like svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH followed by merging rev 46647 to the new branch.

* Get rid of __context__, per the latest changes to PEP 343 and python-devGuido van Rossum2006-05-021-8/+5
| | | | | | | | discussion. There are two places of documentation that still mention __context__: Doc/lib/libstdtypes.tex -- I wasn't quite sure how to rewrite that without spending a whole lot of time thinking about it; and whatsnew, which Andrew usually likes to change himself.
* Implement MvL's improvement on __context__ in Condition;Guido van Rossum2006-04-251-5/+1
| | | | | this can just call __context__ on the underlying lock. (The same change for Semaphore does *not* work!)
* Um, I thought I'd already checked this in.Guido van Rossum2006-03-101-6/+0
| | | | | | | Anyway, this is the changes to the with-statement so that __exit__ must return a true value in order for a pending exception to be ignored. The PEP (343) is already updated.
* Updates to the with-statement:Guido van Rossum2006-02-281-0/+29
| | | | | | | | | | | | | | | | - New semantics for __exit__() -- it must re-raise the exception if type is not None; the with-statement itself doesn't do this. (See the updated PEP for motivation.) - Added context managers to: - file - thread.LockType - threading.{Lock,RLock,Condition,Semaphore,BoundedSemaphore} - decimal.Context - Added contextlib.py, which defines @contextmanager, nested(), closing(). - Unit tests all around; bot no docs yet.
* Prevent threading.Thread.join() from blocking when a previous call raised anBrett Cannon2005-11-231-16/+18

* Fixed typo in verbose output.Brett Cannon2005-01-271-1/+1

* threading._DummyThread.__init__(): document obscure new code.Tim Peters2005-01-081-3/+9
| | | | | | | | test_threading.test_foreign_thread(): new test does a basic check that "foreign" threads can using the threading module, and that they create a _DummyThread instance in at least one use case. This isn't a very good test, since a thread created by thread.start_new_thread() isn't particularly "foreign".
* In _DummyThread objects the lock stored in __block (allocated thanks toBrett Cannon2005-01-081-0/+1
| | | | | | | | _Thread.__init__) was never used. This is a waste since locks use OS primitives that are in limited supply. So the lock is deleted in _DummyThread.__init__ . Closes bug #1089632.
* Thread.__delete: Discussion of internal obscurities belongs in commentsTim Peters2004-07-211-31/+28
| | | | | | | | rather than in docstrings. Rewrote so that _active_limbo_lock is released no matter what happens (it could have been left locked if _sys got None'd out). Use "in" in preference to has_key() for dict lookup. Don't bother looking for 'dummy_threading' in sys.modules unless KeyError is raised. Since the heart of the method is the del, do that in only one place.
* Fix bug where a KeyError was raised if -O was being used for the interpreterBrett Cannon2004-07-211-1/+33
| | | | | | | | | and Thread.__delete() was called after a Thread instance was created. Problem resulted from a currentThread() call in an 'assert' statement being optimized out and dummy_thread.get_ident() always returning -1 and thus overwriting the entry for the _MainThread() instance created in 'threading' at import time. Closes bug #993394.

* threading.Thread objects will now print a traceback for an exception raisedBrett Cannon2004-07-031-2/+38
| | | | | | | during interpreter shutdown instead of masking it with another traceback about accessing a NoneType when trying to print the exception out in the first place. Closes bug #754449 (using patch #954922).
* Remove calls to currentThread() in _Condition methods that were side-effect.Brett Cannon2004-03-081-2/+0
| | | | | | | | | Side-effects were deemed unnecessary and were causing problems at shutdown time when threads were catching exceptions at start time and then triggering exceptions trying to call currentThread() after gc'ed. Masked the initial exception which was deemed bad. Fixes bug #754449 .
