* Issue #14753: Make multiprocessing treat negative timeouts as it did in 3.2Richard Oudkerk2012-05-103-27/+4
| | | | | | | | In Python 3.2 and earlier, Process.join() and Connection.poll() treated negative timeouts as zero timeouts. Earlier versions from the 3.3 line of development treat them as infinite timeouts. The patch reverts to the old behaviour.

* | Issue #12328: Fix multiprocessing's use of overlapped I/O on Windows.Antoine Pitrou2012-03-052-116/+217
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also, add a multiprocessing.connection.wait(rlist, timeout=None) function for polling multiple objects at once. Patch by sbt. Complete changelist from sbt's patch: * Adds a wait(rlist, timeout=None) function for polling multiple objects at once. On Unix this is just a wrapper for select(rlist, [], [], timeout=None). * Removes use of the SentinelReady exception and the sentinels argument to certain methods. concurrent.futures.process has been changed to use wait() instead of SentinelReady. * Fixes bugs concerning PipeConnection.poll() and messages of zero length. * Fixes PipeListener.accept() to call ConnectNamedPipe() with overlapped=True. * Fixes Queue.empty() and SimpleQueue.empty() so that they are threadsafe on Windows. * Now PipeConnection.poll() and wait() will not modify the pipe except possibly by consuming a zero length message. (Previously poll() could consume a partial message.) * All of multiprocesing's pipe related blocking functions/methods are now interruptible by SIGINT on Windows.

| | | | | | | | | | | | | | | | | | | | | | | | The public names (Thread, Condition, etc.) used to be factory functions returning instances of hidden classes (_Thread, _Condition, etc.), because (if Guido recalls correctly) this code pre-dates the ability to subclass extension types. It is now possible to inherit from Thread and other classes, without having to import the private underscored names like multiprocessing did. A doc update will follow: a patch is under discussion on the issue.
