Usage: python zrdun.py [zrdun-options] program [program-arguments] Options: -C/--configure URL -- configuration file or URL -S/--schema XML Schema -- XML schema for configuration file -b/--backoff-limit SECONDS -- set backoff limit to SECONDS (default 10) -d/--daemon -- run as a proper daemon; fork a subprocess, setsid(), etc. -f/--forever -- run forever (by default, exit when backoff limit is exceeded) -h/--help -- print this usage message and exit -s/--socket-name SOCKET -- Unix socket name for client (default "zdsock") -u/--user USER -- run as this user (or numeric uid) -m/--umask UMASK -- use this umask for daemon subprocess (default is 022) -t/--transcript FILE -- transript of output from daemon-mode program -x/--exit-codes LIST -- list of fatal exit codes (default "0,2") -z/--directory DIRECTORY -- directory to chdir to when using -d (default off) program [program-arguments] -- an arbitrary application to run This daemon manager has two purposes: it restarts the application when it dies, and (when requested to do so with the -d option) it runs the application in the background, detached from the foreground tty session that started it (if any). Exit codes: if at any point the application exits with an exit status listed by the -x option, it is not restarted. Any other form of termination (either being killed by a signal or exiting with an exit status not listed in the -x option) causes it to be restarted. Backoff limit: when the application exits (nearly) immediately after a restart, the daemon manager starts slowing down by delaying between restarts. The delay starts at 1 second and is increased by one on each restart up to the backoff limit given by the -b option; it is reset when the application runs for more than the backoff limit seconds. By default, when the delay reaches the backoff limit, the daemon manager exits (under the assumption that the application has a persistent fault). The -f (forever) option prevents this exit; use it when you expect that a temporary external problem (such as a network outage or an overfull disk) may prevent the application from starting but you want the daemon manager to keep trying.
