* the get method on a queue object has a "block" flag. You can effectively poll your queues something like this:
#untested code
#a_done, b_done and c_done are just checks to see if that particular document is done
while not (a_done and b_done and c_done):
got_a, got_b, got_c = False, False, False
item_a, item_b, item_c = None, None, None
while (not a_done) and (not got_a):
try:
item_a = queue_a.get(0) #the 0 says don't block and raise an Empty exception if there's nothing there
Actually, it is just fine to let get() block, as long as I put(None) on the queue when I reach document_end and test for it (removing it from the "list of queues to read" when get() returns 'None').
I rewrote my test script (the one I sent to the NG) to use Queues this way, and it works well. It's also a lot easier to read/follow. Currently I'm implementing it in my application.
I'm glad I don't get paid by the number of lines I write, there are going to be less lines at the end of today ;)
Thanks a lot for the pointers. -- http://mail.python.org/mailman/listinfo/python-list
