Hi,
I have a problem:
1. Assuming that my application is a SOAP server that uses SOAPpy,
2. I am given port 35021 for use.
What I normally do (simply) is:
functionlist = [<some exposed functions>]
import SOAPpy
server = SOAPpy.SOAPServ er((<some host>, 35021))
for func in functionlist: server.register Function(func)
server.serve_fo rever()
My question is: How can I shutdown this server and reuse port 35021 when
my functionlist changes?
Currently, after killing the python process which runs this SOAP server,
the port (35021 in this case) cannot be re-used, as though it is still
phantom-ly bounded to some process (which should have been killed).
Thanks in advance.
Cheers

It shouldn't be that way. Either you still have some process lying
around hogging the port. Or the OS needs a while to re-enable the port
for allocation. That happened to me quite a few times.
Shutting down gracefully might speed up things I guess.

I am under the impression that SOAPpy.SOAPServ er.serve_foreve r() is an
"endless" loop. I had been suggested to see if there is a method of
SOAPpy.SOAPServ er (which I can call through a wrapper function in
functionlist) that can enable me to gracefully shutdown the server.
Any advice?
Thanks

This phenomenon is explained here: http://hea-www.harvard.edu/~fine/Tech/addrinuse.html
or the Unix socket FAQ ( http://www.faqs.org/faqs/unix-faq/socket/) 2.7
Normally the solution is to set the SO_REUSEADDR option in the socket (the
original one) before binding it:
s.setsockopt(so cket.SOL_SOCKET ,socket.SO_REUS EADDR,1)
However, SOAPPy does that already so it should work.

serve_forever is inherited from SocketServer.Ba seServer and it's just an
infinite loop calling self.handle_req uest() over and over.
You have to break out of the loop somehow and call self.server_clo se().
Something like this (untested):
def serve_forever(s elf):
while not self.some_flag_ to_indicate_it_ has_to_stop:
self.handle_req uest()
self.server_clo se()

Hi,
Can anyone provide me with sample code that will allow me to use
SOAPpy with a WSDL file using HTTP basic authentication? The only
thing I've been able to find on the net is SOAPpy.URLopener. However,
I am unclear what the relationship is between SOAPpy.URLopener and
SOAPpy.WSDL is.
Is it as straightforward as this?
