Hello all, I am having a external method problem. In Zope I added an external method object which is a simple list sorting script. The script sorts a list, loads a class instance which does a socket connection over ssl and returns a response. Easy enough, but... when the ext method is called from Zope it takes about a minute to return a response and the CPU usage goes up to 100% the entire time. However, when I run the same script from the python interpreter, it does its business and returns in about a second. Running the list sorting ext method from Zope without the extra class instance returns my list in .01 seconds.

So, I am asuming it is a thread issue with Zope and my socket connection class? Should I open another Python process to do the socket connection using popen? Should I increase the thread count in Zope? (It didn't seem to make much difference running at 8thds vs. 4thds BTW). Should I attempt to run the class in its own thread?

This sounds very strange to me. I run multiple connections from an external method using urllib (which uses sockets, of course) and don't see that problem (Windows 2000, Zope 2.3.3). That's not using ssl, though. Maybe something else is going on. Can you comment out the socket connection and return a dummy response? If so, do you still get the minute's delay or a quick return? Can you be sure that the socked is opened with the same parameters using the interpreter as whe called from Zope? I wonder if somehow the ssl authentication is getting interfered with by Zope, though I don't see why. Also, even if you run it in a thread, the thread calling routine will still have to wait for the thread to return, so it's possible you won't actually gain much. Could you say which OS and Zope version you are using, in case they ring a bell for someone? Cheers, Tom P
