Daisy wiki wrapper script should check/wait 'smart' for the repository to run!
------------------------------------------------------------------------------

         Key: DSY-431
         URL: http://issues.cocoondev.org//browse/DSY-431
     Project: Daisy
        Type: Improvement
 Reporter: Marc Portier
    Priority: Minor


Now that we have the wrapper scripts packaged in the distro I can assume people are going to be hooking them up easily as init.d start-stop scripts on their linux distro (or as services on windows)

However, on linux I've seen this cause the wiki to start up before the repo is actually running and thus make the wiki initialize badly (typical symptom is a cocoon error page talking about an initialization error)


In our experimental debian package we already have scripts with a trick for this (see below)

Before hacking this in as a patch for the shell scripts, I'ld like to learn if Windows services have similar issues, and if we could find a common solution?


wait_for_server_start () {
  port=$1
  counter=0
  serverstatus=`netstat -l  | grep -e "^tcp.*:${port}"`
  while [[ -z "${serverstatus}" &&  ${counter} -lt 12 ]]; do
    sleep 2s
    serverstatus=`netstat -l  | grep -e "^tcp.*:${port}"`
    let counter=counter+1
  done
  if [ -z "${serverstatus}" ]; then
    echo Not listening to port $port .  Exiting ...
    exit 1
  else
    echo Listening to port $port
  fi
}


+ call this wait...() function from the start()
