[DRE-maint] Bug#762493: ruby-jekyll-watch: Package should suggest ruby-rb-inotify

[Thomas Prokosch]

Package: ruby-jekyll-watch
Version: 1.0.0-1
Severity: minor

Jekyll is crashing under the following conditions:
1. ruby-jekyll-watch is installed
2. ruby-rb-inotify is not installed
3. The user runs "jekyll build -w" or "jekyll serve -w" without the "--force_polling" command line option.

The error message is:

/usr/lib/ruby/vendor_ruby/celluloid/mailbox.rb:69:in `sleep': No live threads left. Deadlock? (fatal)
	from /usr/lib/ruby/vendor_ruby/celluloid/mailbox.rb:69:in `wait'

	from /usr/lib/ruby/vendor_ruby/mercenary.rb:22:in `program'
	from /usr/bin/jekyll:18:in `<main>'

This is just a long way of saying that the inotify interface is not available.

As Jekyll works fine with the "-w" and "--force_polling" options combined, even when the ruby-rb-inotify package is not installed, I am using "severity: minor" to report this bug.

However, it would be nice if the user would be reminded to install the ruby-rb-inotify package somehow, eg by recommending this package, or printing an appropriate error message.

Best wishes,
Thomas
