http_proxy variables with no scheme gives confusing invalid url error

[Johan Dahlberg]

As being affected by Bug #186920
I cannot use "bzr branch lp:do-plugins", so I tried access without the launchpad plugin:

> bzr branch http://bazaar.launchpad.net/~do-plugins/do-plugins/trunk
bzr: ERROR: Invalid url supplied to transport: "Host empty in: <proxy-server>:80"

(The actual proxy server name is replaced with <proxy-server> above and in the supplied log file.
The proxy settings seem to be ok, as links and wget are working just fine for both http and https access.)

This problem seems to be similar, but not identical, to launchpad-bazaar Bug #253451

I attach the log for the following commands:
> bzr -Dhttp branch lp:do-plugins
> bzr -Dhpss branch bzr+ssh://<email address hidden>/~do-plugins/do-plugins/trunk
> bzr -Dhttp branch http://bazaar.launchpad.net/~do-plugins/do-plugins/trunk
> bzr -Dhttp branch https://bazaar.launchpad.net/~do-plugins/do-plugins/trunk

The first two commands fail when resolving the hostname "Name or service not known" (as in Bug #186920),
while the latter two seem to fail when about to contact the proxy server.

what is your http_proxy variable set to?

[Johan Dahlberg (dahlberg-ti)]

http_proxy=<proxy-server>:80
https_proxy=<proxy-server>:80

Where <proxy-server> is a host name which can be pinged without problems.

use
http://<proxy-server>:80/
which is the way bzr interprets those variables.

(If you had a https proxy server it would be
https://<proxy-server>:443/
or whatever, but _very_ few people actually have that, nearly everyone
talks to their proxy over http).

Thanks a lot! That works like charm.

Well, no bug then, just an error message that perhaps could be somewhat more helpful.

Certainly. Lets see if I remember the syntax:

Hmm I was facing this problem and asked to lord "Google" to answer me. Finally he did.

Anyways to error message is misleading.It can be something like "please add http:// to the hostname".
I think it will be better if bzr can add the "http://" token automatically.
