thanks
I think I found out what this bug is about. If I'm wrong, I hope the
original submitter or someone else can provide more info.
I'm testing with the latest versions of straw and python-adns, just as the
submitter. In my tests, refreshing and subscribing work, but they take
intolerably long (at least ten minutes). For me, this has been the case
with the versions in Sarge too.
The following change makes refreshing and subscribing work quickly for me:
--- LookupManager.py.orig 2006-02-18 18:22:44.000000000 +0200
+++ LookupManager.py 2006-11-13 17:04:24.000000000 +0200

def poll(self, timeout=0.1):

+ self.queryengine.run(0)
# Blocking version: use normal lookups, no threads
class BlockingLookupManager:
The problem is that without the change this function will use up all of
the given time and leave no time for other network IO as seen in
URLFetch.py lines 165-170:
# keep the network running
now = time.time()
lookup_manager.poll(timeout)
timeout -= (time.time() - now)
if timeout > 0.0:
asyncore.poll(timeout)
The change is also in line with how the ThreadLookupManager is
implemented: if there are no results pending, poll doesn't take time at
all.
Hope this helps,
Tuukka
