Description Lucian Muresan 2012-04-18 21:15:25 UTC

I guess the problem described in #366791 no longer occurs with current net-libs/webkit-gtk-1.8.0, and right now libproxy has no ability to really show its strength, to get the "right" proxy for a given URL from a PAC file...

Reproducible: Always

Steps to Reproduce:
1.emerge --oneshot libproxy

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N     ] net-libs/libproxy-0.4.7-r1::googoo  USE="-gnome -kde -mono -networkmanager -perl -python -test -webkit"

2.  _PX_DEBUG=1 ftp_proxy=pac+ftp://server/path/to/proxy.pac proxy ftp://ftp.mozilla.org/pub/ls-lR.gz

Actual Results:  
Using config: 23envvar_config_extension
Using ignore:
Config is: pac+http://server/path/to/proxy.pac
PAC received!
Unable to find a required pacrunner!
direct://

Expected Results:  
Config is: pac+http://server/path/to/proxy.pac
PAC received!
Using pacrunner: 26webkit_pacrunner_extension
Pacrunner returned: PROXY proxy-server-you-should-use:port
http://proxy-server-you-should-use:port

Created attachment 309463 [details, diff]
ebuild patch to libproxy-0.4.7 to enable webkit

Now, with net-libs/webkit-gtk-1.8.0:2 or net-libs/webkit-gtk-1.8.0:3 this no longer crashes with USE="-kde webkit", even with nvidia drivers. See also #366791

Comment 2 Lucian Muresan 2012-04-18 21:23:12 UTC

In my description above, please ignore the fact that I'm emerging my already modified ebuild from my overlay, it's with USE="-webkit" anyway so actually does the same as the one from the official tree.
Also, I a little typo/copy/paste error, allowed "pac+  " scheme is only "pac+http", not "pac+ftp", but the result is the same. I had to edit the output texts used to show how to reproduce, that's the reason for the typo.

Fixed in libproxy-0.4.10; sorry for the long wait!
