Thanks Daniel for the bug and the fix. I know its not a ideal fix, but
it should be good enough (and most importantly minimal enough) for
jaunty. I do some investigation now into a fix based on urrlib2 (it just
need to be made to do a HEAD request on http and a size() rquest on
ftp). But init_proxy() should deal with all the common cases for setting
up http_proxy

Binary package hint: update-manager
+
+ TEST CASE:
+ 1. define a proxy server somewhere (gconf, apt.conf, synaptic)
+ 2.use iptables to disallow access to port 80
+ 3. run update-manager and click on the "upgrade" button
+ 4. verify that the upgrade hangs
+
+ 4. install update-manager from jaunty-proposed
+ 5. repeat step 3
+ 6. verify that it now continues
When updating to 9.10 from from 9.04, the update-manager uses a utility
function called "UpdateManager.Core.utils.url_downloadable". This
function skips urllib2 - which is properly configured to use the proxy
settings - and instead directly interacts with httplib, which requires
the caller to properly set up the request in order to use the proxy.
Changing the url_downloadable function to use the proxy resolves the
issue.
Specifically, I after:
- if scheme == "http":
- import httplib
- try:
+ if scheme == "http":
+ import httplib
+ try:
I added:
- proxy = os.getenv('http_proxy')
- if (proxy):
- path = scheme + netloc + path
- netloc = proxy
+ proxy = os.getenv('http_proxy')
+ if (proxy):
+ path = scheme + netloc + path
+ netloc = proxy
This resolved the problem. This, however, isn't really a fix - it relies
on the fact that init_proxy sets the http_proxy environment variable and
ignores anything else that might set up urllib2 to properly use a proxy
server.
