I'd like to know why the following doesn't work.
from twisted internet import defer, reactor
from twisted.python.failure import Failure
import twisted.names.client
def do_lookup(do_lookup):
d = twisted.names.client.getHostByName(domain)
d.addBoth(lookup_done)
def lookup_done(result):
print 'result:', result
reactor.stop()
domain = 'twistedmatrix.com'
reactor.callLater(0, do_lookup, domain)
reactor.run()
Results in:
result: [Failure instance: Traceback
(failure with no frames): <class
'twisted.names.error.ResolverError'>:
Stuck at response without answers or
delegation ]
Correcting your example to the following, so that it is syntactically valid:
from twisted.internet import reactor
import twisted.names.client
def do_lookup(domain):
d = twisted.names.client.getHostByName(domain)
d.addBoth(lookup_done)
def lookup_done(result):
print 'result:', result
reactor.stop()
domain = 'twistedmatrix.com'
reactor.callLater(0, do_lookup, domain)
reactor.run()
I get:
$ python so-example.py
result: 66.35.39.65
So, to answer your question: your local DNS environment is broken, not twisted.names. Or maybe there's a bug. You'll need to track it down further.
