Sorry, you have to post from a subscribed address. We don’t generate
an automatic response since several RBL’s black list us when we do…
I have a flow graph which diverges down several pathways, and ends in
several separate gr_msg_queue’s, my initial design was to have one python
thread running as a handler for each queue,
so each handler process would sit on delete_head() until a new item arrived.
However it seems that if any more than a single python thread is using
delete_head() at one time, random memory access crashes seem to occur.
Do you have a simple test case that reproduces it?
If it’s our bug we should fix it.
Is there a clean way to block on multiple queues currently in svn ?
Not right now. However you may be able to use a loop that includes
m0 = msgq0.delete_head_nowait()
m1 = msgq1.delete_head_nowait()
or something similar
I saw reference to a message passing interface of some sort upcoming,
but I assume this is not currently available ?
Not yet ready for prime time.
