Hello,
Python 2.7.1 Suds 0.4 Windows XP SP3
I have been using the suds client (suds.client.Client) for testing some SOAP interfaces and I have recently come across some unpredictable behaviour.
Basically what is happening is I am *sometimes (more often than not)* unable to create a client from WSDL source.
I guess an example would better shed light on what I mean.
For example I run the following
from suds.client import Client client = Client("http://localhost:8000/sms/soap/?wsdl")
and I get this traceback

I can later call* the same* client creation code and successfully create a usable client.
One last thing. Is there anyway to speed up the creation of the clients. Sometimes for a simple WSDL it takes up to 1 minute to create a client...
Thanks, Craig

Since the error is being raised in httplib, it would seem your web server is not responding correctly (bad status line). I would try doing several test calls with just httplib (or urllib2) against this same URL and see if you can replicate the error.
One last thing. Is there anyway to speed up the creation of the clients. Sometimes for a simple WSDL it takes up to 1 minute to create a client...
Define "simple." :) I've used some pretty complex WSDL files, and it's never taken as long as a minute. The Sax parser is pure python, so it might not be the fastest thing out there. Also, look into the caching options.

Slow client creation times may also point to external imports that take time to resolve, load, parse, or connect to. I would run a packet capture while you instantiate your client so you can see exactly what may be going on. I've loaded some fairly large WSDLs and it's never taken it a minute...
