Instance Method Details

#run_with_timeout(directory, command, timeout, tick) ⇒ Object

The following code is based on code originally copied from gist.github.com/lpar/1032297 Gist title: lpar/timeout.rb

Runs a specified shell command in a separate thread. If it exceeds the given timeout in seconds, kills it. Returns any output produced by the command (stdout or stderr) as a String. Uses Kernel.select to wait up to the tick length (in seconds) between checks on the command’s status

If you’ve got a cleaner way of doing this, I’d be interested to see it. If you think you can do it with Ruby’s Timeout module, think again.
