Just wanted to update you on some info; also I had some queries :: The "#defines" are needed in all the avahi-modules (avahi-core, avahi-daemon, etc.), so it needs to have itself pre-processed from the common "avahi-common" module. Thankfully, the two "#defines" are present in "avahi-common/defs.h". This "avahi-common" is the basic common module, which is linked to other modules (avahi-core, avahi-daemon, etc) So far, so good. =================================================================================== Also, Avahi has "/etc/avahi/avahi-daemon.conf", which is read by load_config_file() in "avahi-daemon/main.c". So, that was the first place I tried adding the two new config values. But.. the problem starts now.. If the two additional values are read from the "static int load_config_file(DaemonConfig *c)" method in "avahi-daemon/main.c" (via "/etc/avahi/avahi-daemon.conf"), that does not work out. Reason is that, because "avahi-daemon" requires "avahi-core" to complete its linking process, whereas "avahi-core" would need "avahi-daemon" to complete its linking process (since the two values will be read from the context of "avahi-daemon"). That puts us in a catch-22 situation. =================================================================================== So, actually, the right place to load the complete config is in "avahi-common" module; but as of now, even in F17, the "static int load_config_file(DaemonConfig *c)" method resides in the "avahi-daemon" module :\ Anyways, so, I have put in the code to load the two new config files, in "avahi-common/load_ttl_config.c". =================================================================================== Thanks and Regards, Ajay <div class="gmail_quote">On Mon, Jul 9, 2012 at 9:45 PM, Ajay Garg <<a href="mailto:ajaygargnsit@gmail.com" target="_blank">ajaygargnsit@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0pt 0pt 0pt 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hi all.

I ran into a issue, as described at <a href="https://bugs.freedesktop.org/show_bug.cgi?id=51501" target="_blank">https://bugs.freedesktop.org/show_bug.cgi?id=51501</a> I followed these steps :: a) I changed the values to #define AVAHI_DEFAULT_TTL_HOST_NAME (20) #define AVAHI_DEFAULT_TTL (20) b) Re-compiled the RPMS c) Upgraded to these new RPMS on my F17. And voila, the contacts-disappearance signals did emit (after about 20 seconds) !!! The same approach solved the issue on F14 as well !!! So, now I intend to make the values of these 2 "#defines" customizable. My queries are :: (i) Is it possible already? (ii) If answer to (i) is "no", perhaps GConf might help? The thing that worries me is in what context should Gconf-entries be populated, since avahi runs as a daemon. Will be grateful to a reply.
