* bpo-31653: Remove deadcode in semlock_acquire() (#4091)Victor Stinner2017-10-231-4/+4
| | | | | | | | | | Fix the following Coverity warning: >>> CID 1420038: Control flow issues (DEADCODE) >>> Execution cannot reach this statement: "res = sem_trywait(self->han...". 321 res = sem_trywait(self->handle); The deadcode was introduced by the commit c872d39d324cd6f1a71b73e10406bbaed192d35f.

* bpo-6532: Make the thread id an unsigned integer. (#781)Serhiy Storchaka2017-03-231-1/+1
| | | | | | | | | | | * bpo-6532: Make the thread id an unsigned integer. From C API side the type of results of PyThread_start_new_thread() and PyThread_get_thread_ident(), the id parameter of PyThreadState_SetAsyncExc(), and the thread_id field of PyThreadState changed from "long" to "unsigned long". * Restore a check in thread_get_ident().

| | | | | Replace 0 with (0) to ignore a compiler warning about dead code on "((int)(SEM_VALUE_MAX) < 0)": SEM_VALUE_MAX is not negative on Linux.

* | Issue #12328: Fix multiprocessing's use of overlapped I/O on Windows.Antoine Pitrou2012-03-051-27/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
