Small bug in using file_auto_define. I am using files_auto_define to detect
if cf-served has been updated and restart if so:
files_auto_define => { "/opt/cfengine/bin/.*" };
...
processes:
"$(cf3_processes)"
signals => { "kill" },
ifvarclass => canonify("auto__opt_cfengine_bin_$(cf3_processes)");
"$(cf3_processes)"
restart_class => canonify("start_$(cf3_processes)");
commands:
"/opt/cfengine/bin/$(cf3_processes)"
ifvarclass => canonify("start_$(cf3_processes)");
"/opt/cfengine/bin/$(cf3_processes)"
ifvarclass => canonify("auto__opt_cfengine_bin_$(cf3_processes)");
}
This works pretty slick, but why do I need to added the extra test using the
auto class?
"/opt/cfengine/bin/$(cf3_processes)"
ifvarclass => canonify("auto__opt_cfengine_bin_$(cf3_processes)");
Does cfengine do a snapshot of the process table, so when I kill cf-serverd,
it doesn't know that it is died when it parses the restart_class on the next
stanza? Either way, the extra lines don't hurt. But that is not the bug for
which I am posting.
>From verbose logging:
cf3 !! Image file /opt/cfengine/bin/cf-serverd out of date (should be copy
of XXXXXXX)
cf3 -> Updated /opt/cfengine/bin/cf-serverd from source XXXXXXXXXX

cf3 -> Copy of regular file succeeded XXXX/cf-serverd.cfnew
cf3 Object /opt/cfengine/bin/cf-serverd had permission 600, changed it to

I traced it back to MakeReport, but didn't dig deep enough to find the
actual problem as it is a minor reporting bug and doesn't effect the
operation of cfengine. Below is the debugger output up to where is croaks:
