[Serusers] Re: t_pick_branch failed

[Daniel Poulsen]

Sorry- forgot to include these blocks. The hunt table is basically a 
duplicate of aliases that we use to store hunt sequence info.

###
# Hunt to the next number in sequence
route[8] {
# See if we're in a hunt
if(search("P-hint: pt-hunt")) {
xlog("L_NOTICE",
"wanted to hunt, but hunt already in progress\n");
break;
};

# Assumes URI has been revert and prefixed with "h#-"
# Also assumes t_on_failure (#+1) has been set.
xlog("L_NOTICE", "%ci: r8: hunt on %ru\n");
if(lookup("hunt")) {
xlog("L_NOTICE",
"%ci: r8: hunt changed URI to %ru, relaying\n");
append_branch();
append_hf("P-hint: pt-hunt\r\n");
setflag(9);
t_relay();
break;
} else {
xlog("L_NOTICE",
"%ci: r8: no further hunts, giving up\n");
};

break;

}

failure_route[1] { revert_uri(); prefix("h1-"); t_on_failure("2"); route(7); 
}
failure_route[2] { revert_uri(); prefix("h2-"); t_on_failure("3"); route(7); 
}
failure_route[3] { revert_uri(); prefix("h3-"); t_on_failure("4"); route(7); 
}
failure_route[4] { revert_uri(); prefix("h4-"); t_on_failure("5"); route(7); 
}
failure_route[5] { revert_uri(); prefix("h5-"); t_on_failure("6"); route(7); 
}
failure_route[6] { revert_uri(); prefix("h6-"); t_on_failure("7"); route(7); 
}
failure_route[7] { revert_uri(); prefix("h7-"); t_on_failure("8"); route(7); 
}
failure_route[8] { revert_uri(); prefix("h8-"); t_on_failure("9"); route(7); 
}
failure_route[9] { xlog("L_ERR", "too many hunts!\n"); }
