Capistrano Multistage file encoding gotcha

Posted by dansketcher on January 31, 2013

We use Capistrano exclusively for deployment to live and pre-live environments, so imagine my surprise when, copying a configuration into files on a new app, that I started seeing this:

Flexo:app dansketcher$ cap production misc:show_path
    triggering load callbacks
  * 2013-01-31 13:17:53 executing `production'
    triggering start callbacks for `misc:show_path'
  * 2013-01-31 13:17:53 executing `multistage:ensure'
  * 2013-01-31 13:17:53 executing `misc:show_path'
  * executing "echo $PATH"
`misc:show_path' is only run for servers matching {}, but no servers matched

The ‘production’ stage was configured, but even adding things like raise '' in the config/deploy/production.rb file failed to have an effect. It was like the file wasn’t even being loaded, except that trying to execute against a non-existent stage (‘work_damn_you’ stage, anyone?) did raise an error.

In the end, out of desperation, I ran dos2unix on the files, which weirdly complained about a binary file. Hrm. I re-saved the files as UTF-8 and all started working.

So be warned.
