> jsvc log rotation support
> -------------------------
> 
> Key: DAEMON-95
> URL: https://issues.apache.org/jira/browse/DAEMON-95
> Project: Commons Daemon
> Issue Type: Improvement
> Affects Versions: 1.0.1
> Environment: Linux PC i686 Fedora Core 6
> Reporter: Mike Polek
> Priority: Minor
> 
> Currently, tomcat does not support proper log rotation for
> the standard output and error files produced when -outfile
> and -errfile are used at startup. The following patch
> 1) upgrades jsvc-unix.c to support proper log rotation using SIGUSR1
> 2) fixes a minor bug with arguments.c where the -procname argument
> can't be used because it was added after the check for the end
> of arguments
> 3) some minor warnings due to missing or incorrect function declarations.
