network_check crashed with InvalidURL in _set_hostport(): nonnumeric port: ' text'

Status changed to 'Confirmed' because the bug affects multiple users.

Also occurs in 12.04 alpha 2.

I managed to reproduce the failure reported in the stack trace by setting an invalid http_proxy environment variable:

http_proxy='http://whatever.com: text' /usr/share/checkbox/scripts/network_check

This would indicate that people observing this problem have set an invalid http_proxy variable. I'd appreciate if people experiencing this bug would let me know what this command run on a terminal shows:

echo http_proxy

Anyway, I'll fix the code so it properly handles the thrown exception.

Note that for SRUing this fix to 0.13.x, the exception handling syntax needs to be adapted to Python2, as it was done Python3-style.

Hello fidji-florian, or anyone else affected,

Accepted checkbox into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/checkbox/0.13.8 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please change the bug tag from verification-needed to verification-done. If it does not, change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Hi,

I took a system with checkbox 0.13.7, and ran the command given in the test section, I get this:
Traceback (most recent call last):
  File "/usr/share/checkbox/scripts/network_check", line 64, in <module>
    sys.exit(main())
  File "/usr/share/checkbox/scripts/network_check", line 40, in main
    results[protocol] = check_url(value)
  File "/usr/share/checkbox/scripts/network_check", line 17, in check_url
    urllib2.urlopen(url)
  File "/usr/lib/python2.7/urllib2.py", line 126, in urlopen
    return _opener.open(url, data, timeout)
  File "/usr/lib/python2.7/urllib2.py", line 400, in open
    response = self._open(req, data)
  File "/usr/lib/python2.7/urllib2.py", line 418, in _open
    '_open', req)
  File "/usr/lib/python2.7/urllib2.py", line 378, in _call_chain
    result = func(*args)
  File "/usr/lib/python2.7/urllib2.py", line 1207, in http_open
    return self.do_open(httplib.HTTPConnection, req)
  File "/usr/lib/python2.7/urllib2.py", line 1146, in do_open
    h = http_class(host, timeout=req.timeout) # will parse host:port
  File "/usr/lib/python2.7/httplib.py", line 693, in __init__
    self._set_hostport(host, port)
  File "/usr/lib/python2.7/httplib.py", line 721, in _set_hostport
    raise InvalidURL("nonnumeric port: '%s'" % host[i+1:])
httplib.InvalidURL: nonnumeric port: ' text'

Then I installed checkbox 0.13.8 from -proposed, ran the same command. I get nothing on the command line, and a small window pops up indicating the http connection failed (understandably, since the proxy is purposefully invalid). This is the correct behavior as indicated by the test case.

Just for kicks, I then set a valid proxy and ran with both checkbox 0.13.7 and checkbox 0.13.8. In both cases it said the connection failed, but that's because the URL they are trying to load no longer exists (see https://launchpad.net/bugs/1065855). This issue is orthogonal to the current bug; I manually modified the network_check script to point to a valid URL, and then it works fine (says HTTP Connection: Success). So the proposed fix is working as expected.

I'll mark verification-done based on the above.

Hello fidji-florian, or anyone else affected,

Testing checkbox 013.9, here's what I did:

1- With checkbox 0.13.7 installed, ran:

http_proxy='http://whatever.com: text' /usr/share/checkbox/scripts/network_check

Result: Error trace as seen in the original report.

2- With checkbox 0.13.7 installed, ran:

http_proxy='http://gamerunblock.com' /usr/share/checkbox/scripts/network_check

Result: OOPS, a gtk window saying failed to connect. This is because the script points to an invalid URL.

3- Checkbox 0.13.7, manually modified the script to point to a valid URL, ran :

http_proxy='http://gamerunblock.com' /usr/share/checkbox/scripts/network_check

Result: HTTP Connection: success

So the bad behavior in item 1 was observed. Now, with checkbox 013.9:

1- With checkbox 0.13.9 installed, ran:

http_proxy='http://whatever.com: text' /usr/share/checkbox/scripts/network_check

Result: GTK window saying HTTP connection: Failed. (THIS is the fix in action, so it works, yay!)

2- With checkbox 0.13.9 installed, ran:

http_proxy='http://gamerunblock.com' /usr/share/checkbox/scripts/network_check

Result: OOPS, a gtk window saying failed to connect. This is because the script points to an invalid URL.

3- Checkbox 0.13.9, manually modified the script to point to a valid URL, ran :

http_proxy='http://gamerunblock.com' /usr/share/checkbox/scripts/network_check

Result: HTTP Connection: success

So the proposed fix is working as expected. I'll set to verification-done.
