A condition variable allows one or more threads to wait until they are notified by another thread. If the lock argument is given and not None, it must be a Lock or RLock object, and it is used as the underlying lock. Otherwise, a new RLock object is created and used as the underlying lock.

If the calling thread has not acquired the lock when this method is called, a RuntimeError is raised. This method releases the underlying lock, and then blocks until it is awakened by a notify() or notify_all() call for the same condition variable in another thread, or until the optional timeout occurs. Once awakened or timed out, it re-acquires the lock and returns. When the timeout argument is present and not None, it should be a floating point number specifying a timeout for the operation in seconds (or fractions thereof). When the underlying lock is an RLock, it is not released using its release() method, since this may not actually unlock the lock when it was acquired multiple times recursively. Instead, an internal interface of the RLock class is used, which really unlocks it even when it has been recursively acquired several times. Another internal interface is then used to restore the recursion level when the lock is reacquired. zcannot wait on un-acquired lockFNTr) r]rOr3rIreappendr\r[remove ValueError)r8rKwaiter saved_stategotitr&r&r'wait s>      zCondition.waitcCs^d}|}|}|s-|dur#|durt|}n |t}|dkr# |S|||}|r |S)zWait until a condition evaluates to True. predicate should be a callable which result will be interpreted as a boolean value.

When invoked without arguments: if the internal counter is larger than zero on entry, decrement it by one and return immediately. If it is zero on entry, block, waiting until some other thread has called release() to make it larger than zero. This is done with proper interlocking so that if multiple acquire() calls are blocked, release() will wake exactly one of them up. The implementation may pick one at random, so the order in which blocked threads are awakened should not be relied on. There is no return value in this case. When invoked with blocking set to true, do the same thing as when called without arguments, and return true. When invoked with blocking set to false, do not block. If a call without an argument would block, return false immediately; otherwise, do the same thing as when called without arguments, and return true. When invoked with a timeout other than None, it will block for at most timeout seconds. If acquire does not complete successfully in that interval, return false. Return true otherwise.

Arguments are: *group* should be None; reserved for future extension when a ThreadGroup class is implemented. *target* is the callable object to be invoked by the run() method. Defaults to None, meaning nothing is called. *name* is the thread name. By default, a unique name is constructed of the form "Thread-N" where N is a small decimal number. *args* is the argument tuple for the target invocation. Defaults to (). *kwargs* is a dictionary of keyword arguments for the target invocation. Defaults to {}.
