Question

I have a need to frequently run an applescript on my web server. As the server is running rails, and I need access to my models before and after running the script, I thought that a daemon (via the daemons gem) might be appropriate.

In theory this is fairly easy. Below is a simplified example.

#!/usr/bin/env ruby

ENV["RAILS_ENV"] ||= "development"

require File.dirname(__FILE__) + "/../../config/application"
Rails.application.require_environment!

$running = true
Signal.trap("TERM") do 
  $running = false
end

while($running) do

  Rails.logger.info "Daemon running at #{Time.now}.\n"

  # sanity check
  %x{touch /foo.txt}

  # this stops working after a while
  result = %x{/usr/bin/osascript -s o /path/to/the/script.scpt}

  # under normal operation, my applescript spits out a string result
  Rails.logger.info "Result: #{result}.\n"

  sleep 30
end

For testing purposes I've replaced the (somewhat long and time consuming) production applescript with a one-liner. Here it is, in all its glory:

"It Worked!"

Because applescript treats the last line of the script as a return statement, this string gets passed into my result variable and ultimately logged in rails.

This works great - for a while. Eventually though (typically after several hours) the osascript line stops returning results. The daemon is still running but the osascript line, for all I can tell, is completely failing without explanation.

I can say with certainty that the daemon itself has not died because

  • The rails log entries appear at correct intervals, and
  • My sanity check of "foo.txt" regularly updates its last modified time stamp.

I thought I'd post an update to this in case anyone out there is having a similar problem. First off, I've found a workaround. Its an ugly hack for sure, but it gets the job done and it doesn't crash every 2 hours. What I'm doing is establishing an ssh connection every time the job is run, which effectively lets the script run on a clean session.

Net::SSH.start('127.0.0.1', 'username', :password => 'password') do |ssh|
  result = ssh.exec!('/usr/bin/osascript -s o /path/to/the/script.scpt') 
end

And secondly, I've found a large number of crash reports in my ~/Library/Logs/DiagnosticReports directory. More and more I'm starting to believe that this whole ordeal has to do with some kind of session timeout or expiration.

Solution

I have found out via testing about our issues. One question I had for you, is how are you starting the script? Is it started from logging on the machine and starting a terminal in the Mac OSX desktop screen? Or are you ssh'ing into the Mac and starting it from there.

On our daemon that was trying to use the Window Manager (firefox), if we started it via the Terminal.app from the logged in user. It would work fine. If we ssh'd in to start the script (which happens when you use Capistrano to start it) it would work fine until that ssh session was stopped. In the Console you can see the logs:

2/7/11 8:32:13 PM    com.apple.SecurityServer[22]    Session 0x22058d0 destroyed
2/7/11 8:32:13 PM    com.apple.SecurityServer[22]    Session 0x22058d0 dead
2/7/11 8:32:13 PM    com.apple.SecurityServer[22]    Killing auth hosts

This happens after we terminate the SSH session. After it terminates, we would get the errors like you did:

abort() called
LaunchServices: GetOurLSSessionIDInit() returned err #1, 
    securitySessionID == 0x0, vers=10600000 uid=501 euid=501

Instead of starting the script via ssh, we now have a LaunchAgent which will start the script based on WatchPaths with a ~/jobs/ directory. It works out well, and we can still restart the server with capistrano.

I would look in your logs to see if the SecurityServer is destroying a session right about the time the script fails. If so, then maybe you can figure out what is causing the timeout.

OTHER TIPS

AppleScript I believe needs a window manager to run. Are you logged in on that machine, and does the Applescript get triggered as that user?
