[Printing-architecture] cups-browsed - What to do if client.conf redirects to remote CUPS

[Till Kamppeter]

Hi,

cups-browsed works well browsing printer broadcasts from remote servers 
and auto-adding local raw queues pointing to these printers as long as 
CUPS clients are not redirected to remote servers via /etc/cups/client.conf.

If there is such a re-direction, cups-browsed does not make much sense, 
as it cannot manipulate CUPS queues on a remote server. It can even 
misbehave, as

https://bugs.launchpad.net/ubuntu/+source/cups-filters/+bug/1207203

shows.

What I would like to do is to make cups-browsed always connecting to the 
local CUPS daemon, ignoring any client.conf setting. Is this easily 
possible?

Or should I better simply on the first failed attempt to add or remove a 
print queue make cups-browsed shutting down and enter a stand-by loop 
until the cupsServer() output changes?

Sure, don't use cupsServer() to get the default server and don't use CUPS_HTTP_DEFAULT for any http_t * parameters.

The value of cupsServer() is cached for the life of the application.  And while we *do* have a bug tracking a potential change to detect whether the client.conf file(s) have changed, we are also doing our best to move away from static configuration information in order to better function in a mobile world.
