Very wise... gconf would be only looking at the gnome desktop... and once I read that we also support KDE :) A 'difficulty' in most cases, when it comes to PK is it's 'bare' way of detecting proxy settings: It's much too inflexible and can't handle 'multiple proxies' as used in various situations. If you want to use libproxy (or any other reliable way of proxy handling.. does not really matter; libproxy can only help you out) you need to pass every single URL to the proxy helper to detect what the right proxy for exactly this URL would be (think about pac files here). think about a 'typical' setup: - Repo 1: repo.mycomp.com/repository (internal, not reachable through our proxy) - Repo 2: download.o.o/repositories/[...] (external, requires proxy). Obvious the proxy settings vary from 'case to case'. Is PK reading 'proxy ignore' variables? Which ones are supported?

Thanks. In fact, I have tried libproxy, but libproxy also call GConf API, so libproxy also can't get the correct proxy info. Seems the runtime environment is changed in libzypp. Any comment?

I don't know what libzypp should change to prevent GConf from working. AFAIK it does not delete or undefine any environment variable. -- cu, Michael Andres +------------------------------------------------------------------+ Key fingerprint = 2DFA 5D73 18B1 E7EF A862 27AC 3FB8 9E3A 27C6 B0E4 +------------------------------------------------------------------+ Michael Andres YaST Development ma@novell.com SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg) Maxfeldstrasse 5, D-90409 Nuernberg, Germany, ++49 (0)911 - 740 53-0 +------------------------------------------------------------------+ -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org

Most likely the issue is the 'user' libzypp is running as. It's probably in root's context and root does not have any gconf keys set (unless 'it' ever logged in and configured the gnome proxies).

libzypp using gconf api and also libproxy will always query the 'current users' gnome settings. For PK this would probably result in a 'helper' app in the user workspace that can forward the settings using a dbus call or the like...

Helper app? WTF? sorry ;-) I think it's reasonable to expect that either the user configures proxy settings also for root, if he needs to use proxies for whatever reason. Or alternatively that libproxy (or libzypp itself) setuid's to $LOGNAME for querying the proxy info.

Downloading is done by libzypp, either via libcurl or aria2c. Internally zypp works similar to libproxy, there's a method taking an URL and returning the proxy to use.

Just the magic behind libzypps method is far less sophisticated. I'll have a closer look at libproxy.

If there's anything I can help you with libzypp, just let me know. I'll gladly join in here as an upstream dev. Dominique -- To unsubscribe, e-mail: zypp-devel+unsubscribe@opensuse.org For additional commands, e-mail: zypp-devel+help@opensuse.org
