Just an experiment for running daemonized Ost workers, but without requiring Ost.
Assuming a simple worker:
require "app"
Ost[:stuff].each do |item|
# process item
end
Place the worker at ./workers/stuff.rb and then:
$ nost start stuff
That should load the worker in the foreground.
You can daemonize the process by passing the -d flag:
$ nost start -d stuff
If you daemonize, a file containing the daemonized process ID is written
to ./workers/stuff.pid.
Given that start is the default action for running Ost workers it can
be omitted:
$ nost -d stuff
You can kill a daemonized worker by issuing the stop command:
$ nost kill stuff
This will send the TERM signal to the process.
Optionally, you can specify a different directory for the pid file.
$nost -d stuff -p tmp
Will look for the pid file in ./tmp/ instead of the default ./workers/ directory. This is useful if you're using a deploy tool like Capistrano and need to place the pid files in a symlinked dir.
For now, this experiment is only tested on MRI 1.9.2+. I must add that it's working in MRI 2.1.1
