launchpadlib doesn't support system proxy

[Didier Roche-Tolomelli]

Hi,
May I know what steps are needed to have "quickly release" work behind a proxy server:
I get the following message when executing quickly release
Get Launchpad Settings
Traceback (most recent call last):

Aborting

I am able to manually push the source onto launchpad using bzr (had to configure ssh to use corkscrew for this)

AFAICT, Launchpadlib supports proxies, but it does not automatically use the system proxy.

[Robert Collins (lifeless)]

https proxy support in python required special handling in bzr; I suspect that it will here too.

thanks all,
So is there a workaround or configuration I will need to modify for this to get it working with a proxy server? I'm using the same proxy server for http and https.

We have had success using tsocks to make launchpadlib work behind a proxy.

I just did an 'apt-get install tsocks', and then edited /etc/tsocks.conf to point to our server and list address blocks which don't require proxy (hint, but sure to include the subnet the proxy is on in this list). Then just prepend your script with '/usr/bin/tsocks' and see if that works for you.

This is ugly, how can I fix this properly?

[Andreas Fester (andreas-fester)]

This affected me while using Ubuntu's "backportpackage" script (not able to login_anonymously through a proxy). A simple fix which worked is to add the following code into Launchpad.__init__, before calling its super() method, to read proxy information from the http_proxy environment variable:

       if proxy_info is None:
           httpProxy = os.environ.get('http_proxy')
           if httpProxy is not None:
               o = urlparse.urlparse(httpProxy)
               proxy_info = httplib2.ProxyInfo(socks.PROXY_TYPE_HTTP, o.hostname, o.port)

If this is useful, I can also provide a real patch - any feedback welcome, in any case.

This is fix released by mean of lazr.restfulclient 0.13.4
