Currently, I've found the workaround of setting the http_proxy value to the adresse of my bzr repository. The only thing I need to figure out is how can I export this http_proxy value when bzr start ?  There's a start_bzr.bat file which seems to be really convenient but it is not used by Tortoisebzr. So where can I put that variable ? <div class="gmail_quote">On Wed, Feb 18, 2009 at 11:12 AM, Adrian Wilkins <<a href="mailto:adrian.wilkins@gmail.com">adrian.wilkins@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">I also find this rather irksome. The issue is that the common Python libraries will read the proxy config of IE, but does not run PAC scripts (which are typically JScript). If IE is configured statically, I believe that works properly. Python will also respect the HTTP_PROXY environment variable, which takes precedence over the IE config, but I've not found a way to make it say "NO proxy" (using either urllib2 or pycurl). Maybe this : <a href="http://code.google.com/p/pacparser/wiki/PacFilesInPythonWebclients" target="_blank">http://code.google.com/p/pacparser/wiki/PacFilesInPythonWebclients</a> Would be some help... I'd really like to see something like this in the main Python library (batteries included, remember?) since this is such a common scenario. I can't believe that all Python developers are lone wolves operating outside of a corporate firewall. So I don't think this is ultimately a Bazaar issue ; but Bazaar will have to cope with it until it improves. </blockquote></div>
