PyZeroConf Question

[djw]

AMK, thanks for your work on PyZeroConf!

Using PyZeroConf 0.12.

I'm seeing an issue with the Browser.py code. I am scanning for printers
using:

type = "_pdl-datastream._tcp.local."

The list of printers is returned, but every call to getServiceInfo() in
the Listener objectresults in a timeout and None being returned.

I am not trying to publish any services, just discovery.

Also, at the end of the list, the code seems to hang.

Any ideas?

Thanks,

Don

The list of printers is returned, but every call to getServiceInfo() in
the Listener objectresults in a timeout and None being returned.

I suggest compiling Apple's mDNSMonitor and looking at the sequence of
packets. It seems that some Zeroconf services don't respond to the
..getServiceInfo() calls; maybe that's what's happening here.

Also, at the end of the list, the code seems to hang.

That makes sense. The threads that monitor Zeroconf aren't marked as
daemonic, so as long as they're running the main thread doesn't exist. I've
hacked my copy of zeroconf.py to mark the threads as daemonic.
