# Automated deploy script for release a new production and a new
# demo instance of gscf on nbx14. This script needs to be run as
# user tomcat
#
# What it does:
# - checkout the latest source code from svn
# - check if the grails version matches (if not, it downloads and
#   installs that particular grails release to /home/tomcat and
#   updates the symbolic link ~/grails to the new release)
# - build a production war, undeploy the old release and deploy the
#   new release to tomcat's webapps
# - patch some configuration files for the demo version
# - build a demo war, undeploy the old release and deploy the
#   new release to tomcat's webapps
# - restart tomcat
# - patch apache's virtual host configuration files in and trigger
#   restart of apache
#
# Prerequisites:
# - tomcat webabbs should be writable by user tomcat
# - tomcat bin files should be executable by user tomcat
# - in the end this script touches a file to restart apache
#   webserver. This particular cronjob running as root should
#   be available as well
# - obviously, postgres databases should be available (respectively
#   gscf and gscf-demo)
# - a /home/tomcat/.bashrc containing the following lines:
#       export GRAILS_HOME=/home/tomcat/grails
#       export PATH=/home/tomcat/grails/bin:$PATH
#       export JAVA_HOME=/usr/lib/jvm/java-6-sun
#       export CATALINA_OPTS="-Xms1024m -Xmx1024m -XX:MaxPermSize=512m -XX:MaxHeapFreeRatio=70 -XX:MaxGCPauseMillis=10 -XX:+UseConcMarkSweepGC"
