Login Uses Proxy but create() does not

[GoogleCodeExporter]

Confirmed that the WSDL contains only http:// urls and that HTTPS
requirement is disabled in my salesforce org.

Sample code:

#!/usr/bin/python

import sforce
from sforce.enterprise import SforceEnterpriseClient

h = SforceEnterpriseClient('enterprise.wsdl',
proxy={'http':'http://proxyhost:8080'})
lr = h.login('user','pass','token')

print lr

arraymetric = h.generateObject('CustomObjectc__c')
print arraymetric
result = h.create(arraymetric)
print result
h.logout()

Stangely enough, when using the proxy, the login() call suceeds (print of
lr is clean and shows the write userID, a reasonable sessionID, etc).    
However, I then try a create call it stalls, eventually giving me a
traceback inducating that it couldn't reach the service via https directly
(not via proxy):

  File "GetAndUploadFreeSpace.py", line 22, in ?
    result = h.create(arraymetric)
  File "/usr/lib/python2.4/site-packages/sforce/enterprise.py", line 33, in
create
    return super(SforceEnterpriseClient, self).create(xml)
  File "/usr/lib/python2.4/site-packages/sforce/base.py", line 361, in create
    return self._handleResultTyping(self._sforce.service.create(sObjects))
  File "/usr/lib/python2.4/site-packages/suds/client.py", line 539, in __call__
    return client.invoke(args, kwargs)
  File "/usr/lib/python2.4/site-packages/suds/client.py", line 598, in invoke
    result = self.send(msg)
  File "/usr/lib/python2.4/site-packages/suds/client.py", line 623, in send
    reply = transport.send(request)
  File "/usr/lib/python2.4/site-packages/suds/transport/https.py", line 64,
in send
    return  HttpTransport.send(self, request)
  File "/usr/lib/python2.4/site-packages/suds/transport/http.py", line 77,
in send
    fp = self.u2open(u2request)
  File "/usr/lib/python2.4/site-packages/suds/transport/http.py", line 116,
in u2open
    return url.open(u2request)
  File "/usr/lib/python2.4/urllib2.py", line 358, in open
    response = self._open(req, data)
  File "/usr/lib/python2.4/urllib2.py", line 376, in _open
    '_open', req)
  File "/usr/lib/python2.4/urllib2.py", line 337, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.4/urllib2.py", line 1029, in https_open
    return self.do_open(httplib.HTTPSConnection, req)
  File "/usr/lib/python2.4/urllib2.py", line 996, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error timed out>

I wouldn't expect it to be able to hit that directly, thats why i have a
proxy :).  Why is is automatically switching to HTTPS on me?

Salesforce returns a new location after the login() call, and even though my 
internal
call to the SOAP client to change it _shouldn't_ have any effect on the proxy, 
I bet
it's being unset.  Could you try the following?  In base.py, in _setEndpoint, 
after
this line

    self._location = location

could you try adding 

    self._sforce.set_options(proxy = {{'http':'http://proxyhost:8080'})

and see if all subsequent calls work?

If that fixes it, I'll add a quick commit, and if that is the issue, I'll file 
it
with Suds, as that's not the correct behavior IMO.

Thanks for reporting this!

As in your comment, Google Code has stripped the closing curly brace + closing 
paren
for some reason in this line:

    self._sforce.set_options(proxy = {'http':'http://proxyhost:8080'

That didn't actually help, but it got me to figure out the problem:  I note 
that what
salesforce is sending back for location is: 

https://na7-api.salesforce.com/services/Soap/c/18.0/ORGID

Which sforceenterpriseclient then passes off the SUDS, which notes that there 
is no
https proxy in the dictionary, and goes after it directly.

I confirmed that if I manually set the location in setEndpoint to my correct URL
(override anythign you get back from salesforce, note the change from https to 
http):

    location = 'http://na7-api.salesforce.com/services/Soap/c/18.0/ORGID' 

that it does indeed work correctly and thru the proxy.

I'm not really sure who the bug lays with then - it would seem to me that 
salesforce
should probably send back a URL with the same protocol as that with which it was
access (http), and that perhaps the Toolkit should recognize that salesforce is 
being
stupid and munge things as needed.

Thoughts?

If you are interested in a fix, I've attached a modified copy of base.py that
implements a forceHTTP keyword arg that does a simple string replacement that 
fixes
this issue.

Well, the initial request is also going over HTTPS, and it works transparently 
with
your HTTP proxy...  I'm not sure why changing the location causes the requests 
not to
proxy, but if the bug is in Suds, a hack like re-instantiating the SOAP client 
with
the new endpoint may be necessary.  I'll look into this in the next couple of 
days
and report back.

Thanks for the fix, I'd really prefer to get this sorted though, as I don't want
anyone to send their data over HTTP just to work around this issue.

Fair enough.

Thanks for the help.
