Georg Brandl	fc9ea97a18	Move the previously local import of threading to module level. This is cleaner and avoids lockups in obscure cases where a Queue is instantiated while the import lock is already held by another thread. OKed by Tim Peters.	17 years ago
Benjamin Peterson	0fbcf69455	give the threading API PEP 8 names	18 years ago
Georg Brandl	a6168f9e0a	Queue renaming reversal part 3: move module into place and change imports and other references. Closes #2925.	18 years ago
Georg Brandl	6153ab3fee	Queue renaming reversal part 2: move module.	18 years ago
Alexandre Vassalotti	30ece44f2e	Added stub for the Queue module to be renamed in 3.0. Use the 3.0 module name to avoid spurious warnings.	18 years ago
Raymond Hettinger	9e1bc982ff	Add queues will alternative fetch orders (priority based and stack based).	18 years ago
Raymond Hettinger	f59e962b49	Refactor if/elif chain for clarity and speed. Remove dependency on subclasses having to implement _empty and _full.	18 years ago
Raymond Hettinger	1c305dbf97	Fix nit in comment.	19 years ago
Raymond Hettinger	a3c77677ca	... and the number of the counting shall be three.	19 years ago
Skip Montanaro	86116e2b75	document the class, not its initializer	20 years ago
Raymond Hettinger	c4e94b90a8	Don't decrement below zero. And add more tests.	20 years ago
Tim Peters	e33901eb2b	Whitespace normalization.	20 years ago
Raymond Hettinger	fd3fcf0b35	SF Patch #1455676 : Simplify using Queues with daemon consumer threads Adds join() and task_done() methods to track when all enqueued tasks have been gotten and fully processed by daemon consumer threads.	20 years ago
Tim Peters	71ed2201e2	Simplified the new get/get_nowait/put/put_nowait implementations a bit.	22 years ago
Tim Peters	5af0e41482	Bug #788520 : Queue class has logic error when non-blocking I don't agree it had a bug (see the report), so this is not a candidate for backporting, but the docs were confusing and the Queue implementation was old enough to vote. Rewrote put/put_nowait/get/get_nowait from scratch, to use a pair of Conditions (not_full and not_empty), sharing a common mutex. The code is 1/4 the size now, and 6.25x easier to understand. For blocking with timeout, we also get to reuse (indirectly) the tedious timeout code from threading.Condition. The Full and Empty exceptions raised by non-blocking calls are now easy (instead of nearly impossible) to explain truthfully: Full is raised if and only if the Queue truly is full when the non-blocking put call checks the queue size, and similarly for Empty versus non-blocking get. What I don't know is whether the new implementation is slower (or faster) than the old one. I don't really care. Anyone who cares a lot is encouraged to check that.	22 years ago
Raymond Hettinger	756b3f3c15	* Move collections.deque() in from the sandbox * Add unittests, newsitem, and whatsnew * Apply to Queue.py mutex.py threading.py pydoc.py and shlex.py * Docs are forthcoming	22 years ago
Brett Cannon	b42bb5a88a	Add __all__ .	23 years ago
Guido van Rossum	a0934246d3	Use the dummy_thread module in Queue.py and tempfile.py. tempfile.py already contained code to let it run without threads present; for Queue.py this is considered a useful feature too.	23 years ago
Martin v. Löwis	77ac429eff	Patch #572628 : Optional timeouts for put and get.	24 years ago
Raymond Hettinger	46ac8eb3c8	Code modernization. Replace v=s[i]; del s[i] with single lookup v=s.pop(i)	24 years ago
Mark Hammond	3b959dbcaf	Fix bug 544473 - "Queue module can deadlock". Use try/finally to ensure all Queue locks remain stable. Includes test case. Bugfix candidate.	24 years ago
Skip Montanaro	78349072f7	removed __all__ from several modules	25 years ago
Skip Montanaro	e99d5ea25b	added __all__ lists to a number of Python modules added test script and expected output file as well this closes patch 103297. __all__ attributes will be added to other modules without first submitting a patch, just adding the necessary line to the test script to verify more-or-less correct implementation.	25 years ago
Tim Peters	b8c941771a	Variant of Skip's patch 103246 (Remove unneeded string exception compat from Queue).	25 years ago
Jeremy Hylton	a05e293a21	typos fixed by Rob Hooft	26 years ago
Guido van Rossum	4acc25bd39	Mass patch by Ka-Ping Yee: 1. Comments at the beginning of the module, before functions, and before classes have been turned into docstrings. 2. Tabs are normalized to four spaces. Also, removed the "remove" function from dircmp.py, which reimplements list.remove() (it must have been very old).	26 years ago
Guido van Rossum	a41c691371	Make the maxsize constructor argument default to 0 (an unlimited queue size).	27 years ago
Guido van Rossum	9e1721fa79	Tim Peters: + Implements a put_nowait method. + Adds a corresponding Queue.Full exception. + Simplifies the implementation by adding optional "block" args to get() and put(), and makes the old get_nowait() and new put_nowait() one-line redirections to get() and put(). + Uses (much) simpler logic for the nowait cases. + Regularizes the doc strings to something closer to "Guido style" <wink>. + Converts two stray tabs into spaces. + Removes confusing verbiage about the queue "not being available" from the docstrings -- never knew what that meant as a user, and after digging into the implementation still didn't know what it was trying to say.	27 years ago
Guido van Rossum	7e6d18c1c0	Replace all calls to acquire_lock() and release_lock() with acquire() and release() instead.	28 years ago
Guido van Rossum	c09e6b1c0a	Clarify that put blocks when the queue is full. Add some blank lines to doc strings.	28 years ago
Guido van Rossum	45e2fbc2e7	Mass check-in after untabifying all files that need it.	28 years ago
Barry Warsaw	3d96d522ec	(Queue.Empty): When class based exceptions are in force, derive this class from the standard base exception Exception. Otherwise define Queue.Empty as a string exception. (Queue): 8-space to 4-space indentation conversion. Also, basically recast all method comments into docstrings.	29 years ago
Guido van Rossum	dd8cb446e1	Some minute changes.	33 years ago
Guido van Rossum	7bc817d5ba	* Mass change: get rid of all init() methods, in favor of __init__() constructors. There is no backward compatibility. Not everything has been tested. * aiff.{py,doc}: deleted in favor of aifc.py (which contains its docs as comments)	33 years ago
Guido van Rossum	9022fceae8	New module implementing a multi-everything queue.	34 years ago
