Description Miroslav Franc 2013-06-07 09:34:36 EDT
Description of problem:
rlWatchdog while great feature is very limited in that it can only send a signal to each process within a process group once the time is up.  It would be very useful to have additional parameter that would be treated as callback function to be run with PGID of the process group as its first parameter before the processes of that process group are signalled. 

Use case is this: We have a lot of test cases where the tested process might hang/end up the spinning forever and we need to get some info (strace/ltrace/gdb/pstree/lsof/logs//proc/*/... whatever) before we terminate it with SIGKILL.  In this case we would simply write the function that takes PGID as the first argument and let the rlWathdog call it.

I would be willing to write a patch if you are not against it.

Patch to provide callback parameter to rlWatchdog

Does this look sane enough?  I tried it on RHEL 5.9 and Fedora 17.
