Hi John,
thanks for answering. I digged a lot deeper now into the code... and I installed the latest mechanize code separately and tried it out. The latest mechanize version works correct, I can access the site easily with a simple script.
I did then something ugly 
- I copied the latest mechanize code over the mechanize code provided by twill to see if the bug is purely within mechanize. It still doesn't work with Twill, so I suggest that somehow the 2.4er tweaking (I use 2.4) from the side of twill is the cause.
I tried to figure out if the BasicAuth handler is called and came to the following code:
_opener.py (Lines 176 - 180):
# In Python >= 2.4, .open() supports processors already, so we must
# call ._open() instead.
urlopen = getattr(urllib2.OpenerDirector, "_open",
urllib2.OpenerDirector.open)
response = urlopen(self, req, data)
Here I'm lost... no idea why you copy most of the code of urllib2 and then reuse some portions of it... But i don't have the python source of urllib2 and I can't dig deeper.
What I found also interesting is that twill installs a own HTTPHandler (for whatever reason, I don't know what WSGI is...). Maybe this is the cause (_browser.py)?
def build_http_handler():
from mechanize._urllib2 import HTTPHandler
class MyHTTPHandler(HTTPHandler):
def http_open(self, req):
return self.do_open(wsgi_intercept.WSGI_HTTPConnection, req)
return MyHTTPHandler
This will have to wait until next week since I'm leaving now the corporate environment.
Regards,
Andrew
