[distcc] problems with distcc + zeroconf

[shawn]

Distcc + avahi developers,

After upgrading to svn distcc, zeroconf does now work, however it has
some issues, which seem to be woorse when using more threads (-j13 etc)

while it does distribute, occasionally the hosts file is empty, and then
it slowly compiles locally:


distcc[12745] (dcc_parse_hosts)
Warning: /home/shawn/.distcc/zeroconf/hosts contained no hosts; can't
distribute work
distcc[12745] (dcc_zeroconf_add_hosts) CRITICAL! failed to parse host
file.

distcc[12745] (dcc_build_somewhere) Warning: failed to distribute,
running locally instead


I tried to fix this problem, but I need some more input, as I am not
positive what the problem is, nor if my approach is appropriate. (or
even how to debug effectively might be nice---some-but not all-tests i
did with distcc seemed to not even trigger these functions in gdb)

also: attacked typo patch that got bounced the first time
