[Pkg-utopia-maintainers] Bug#598612: /usr/bin/avahi-browse: bash completion slow after machine in lan was shut down

[Uwe Kleine-König]

Package: avahi-utils
Version: 0.6.27-2
Severity: normal
File: /usr/bin/avahi-browse

Hello,

bash completion for ssh calls

	avahi-browse -cpr _workstation._tcp

I often hit the problem that my wife shuts down her machine while I
continue to work on mine.  Still after the machine is off it's still in
avahi's cache and the request to resolve (-r) results in a timeout:

	ukleinek at cassiopeia:~$ set +x; time avahi-browse -cpr _workstation._tcp 
	+;eth1;IPv6;cepheus\032\09100\05811\05895\058bb\05842\058d6\093;Workstation;local
	+;eth1;IPv6;cassiopeia\032\09100\05816\0586f\058b2\0582e\058ae\093;Workstation;local
	+;eth1;IPv4;cepheus\032\09100\05811\05895\058bb\05842\058d6\093;Workstation;local
	+;eth1;IPv4;cassiopeia\032\09100\05816\0586f\058b2\0582e\058ae\093;Workstation;local
	=;eth1;IPv6;cassiopeia\032\09100\05816\0586f\058b2\0582e\058ae\093;Workstation;local;cassiopeia.local;fe80::216:6fff:feb2:2eae;9;
	=;eth1;IPv4;cassiopeia\032\09100\05816\0586f\058b2\0582e\058ae\093;Workstation;local;cassiopeia.local;192.168.178.20;9;
	Failed to resolve service 'cepheus [00:11:95:bb:42:d6]' of type '_workstation._tcp' in domain 'local': Timeout reached
	Failed to resolve service 'cepheus [00:11:95:bb:42:d6]' of type '_workstation._tcp' in domain 'local': Timeout reached

	real	0m5.029s
	user	0m0.004s
	sys	0m0.004s

5s is really unacceptable for tab completion.

Restarting avahi-daemon helps, but having to bother about this is really
annoying.

It would be great if avahi-daemon would notice after the first timeout
that the host is down and remove it from its cache.

Thanks
Uwe
