From: Adam Dickmeiss Date: Wed, 1 Apr 2009 13:31:29 +0000 (+0200) Subject: Update to upstream skeleton of init.d script. X-Git-Url: http://sru.miketaylor.org.uk/cgi-bin?a=commitdiff_plain;h=refs%2Fheads%2Flast_version_wo_sru;p=pazpar2-moved-to-github.git Update to upstream skeleton of init.d script. Make a new init.d script which is based on /etc/init.d/skeleton . This changes a few things, most importantly there is no sleep anymore for restart.. Instead --retry is used . This might very well fix bug #2285. --- diff --git a/debian/pazpar2.init b/debian/pazpar2.init index 03c498b..bd51473 100644 --- a/debian/pazpar2.init +++ b/debian/pazpar2.init @@ -5,76 +5,145 @@ # Required-Stop: $local_fs $remote_fs # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 -# Short-Description: Pazpar2 server -# Description: Debian init script for the Pazpar2 server +# Short-Description: Controls the pazpar2 daemon +# Description: Controls the Pazpar2 Metasearcher daemon +# /usr/sbin/pazpar2 . ### END INIT INFO -PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin -DAEMON=/usr/sbin/pazpar2 +# Do NOT "set -e" + +# PATH should only include /usr/* if it runs after the mountnfs.sh script +PATH=/sbin:/usr/sbin:/bin:/usr/bin NAME=pazpar2 -DESC=pazpar2 +DAEMON=/usr/sbin/$NAME +DAEMON_OPTS="-h" +PIDFILE=/var/run/$NAME.pid +SCRIPTNAME=/etc/init.d/$NAME + +# Exit if the package is not installed +[ -x "$DAEMON" ] || exit 0 + +# Read configuration variable file if it is present +[ -r /etc/default/$NAME ] && . /etc/default/$NAME + +# Load the VERBOSE setting and other rcS variables +. /lib/init/vars.sh -test -x $DAEMON || exit 0 +# Define LSB log_* functions. +# Depend on lsb-base (>= 3.0-6) to ensure that this file is present. +. /lib/lsb/init-functions -# Include pazpar2 defaults if available -if [ -f /etc/default/pazpar2 ] ; then - . /etc/default/pazpar2 -fi +# +# Function that starts the daemon/service +# +do_start() +{ + # Return + # 0 if daemon has been started + # 1 if daemon was already running + # 2 if daemon could not be started + start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON --test > /dev/null \ + || return 1 + start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON -- \ + $DAEMON_OPTS \ + || return 2 + # Add code here, if necessary, that waits for the process to be ready + # to handle requests from services started subsequently which depend + # on this one.
