When watching several directories, only the last is actually watched.

Listen version: 2.7.9

require 'listen'

dirs_to_watch = %w(
  anotherdir
  somedir
)

listener = Listen.to(*dirs_to_watch) do |added, modified, removed|
  puts "Listen fired callback"
end

listener.start.join

The callback only fires when filesystem events occur on the last directory specified.

@e2 any ideas about that one? https://twitter.com/chriseppstein/status/491276956084621312

Works in Linux, so it looks like an issue with darwin/FSEvent adapter (I don't have a Mac to properly test or debug on).

What changed - I needed for each watched directory to have a separate callback (to unify and simplify Listen's adapters). (see https://github.com/guard/listen/blob/master/lib/listen/adapter/darwin.rb)

@thibaudgg - could you confirm I'm using rb-fsevent the right way (i.e. calling watch multiple times on the same FSEvent object before calling run)?

[thibaudgg]

@e2 calling multiple time watch will not work as it overwrites the @paths list each time,I would only call watch once with the list of directories.

@thibaudgg - I need one callback per directory (to later match the original watched directory based on the callback), so the fix is to have multiple FSEvent objects I guess.

Could you review: #257 ?

Ideally I'd add acceptance specs for this (mocking in adapter specs wouldn't make much sense), but looks like way too much work for now - acceptance specs and fixtures currently assume everything happens in a single watched directory.

[e2]

This is still broken after my "fix"- but now only the first directory is watched.

Sorry for the delay, folks, but I had to rework how threads are used and finally add some specs to avoid breaking this every again.
