Very late response, but you are right that this is not a thread-safe implementation.
However, if you take a look at the standard library queue module, you can see that the Queue
base class implements all of the locking required for thread safety. It should be possible to derive something similar to the stdlib queue.PriorityQueue
that wraps a pqdict
. To expose extra functionality like looking up an item by key or modifying a priority, you would have to add additional methods that acquire locks similar to the implementation of Queue.get
.
It would make a nice recipe to add to the examples.
