EOPNOTSUPP raised when hashing UNIX domain socket file

[sunaku]

Hello,

@rahearn is getting EOPNOTSUPP from listen 0.6.0's polling adapter on OSX when it tries to hash a UNIX domain socket file:

rahearn@chris:~/software/golfstats$ bundle exec tork-herald
[Listen warning]:
  Missing dependency 'rb-fsevent' (version '~> 0.9.1')!
  Please add the following to your Gemfile to satisfy the dependency:
    gem 'rb-fsevent', '~> 0.9.1'

  For a better performance, it's recommended that you satisfy the missing dependency.
  Listen will be polling changes. Learn more at https://github.com/guard/listen#polling-fallback.

The solution for this bug is very similar to pull request #64: simply add Errno::EOPNOTSUPP to the rescue list in sha1_checksum() in lib/listen/directory_record.rb.

Thanks for your consideration.

Have you installed rb-fsevent as indicated?

[sunaku]

No, because our goal is to exercise listen's polling adapter on @rahearn's system. If that works correctly, then we will have found a bug in either listen's usage of the rb-fsevent library or in the rb-fsevent library itself. 👮

[thibaudgg]

Ok my bad, can you try the issue73 branch it should be fixed.

[sunaku]

Thanks! I'll report back after @rahearn has tried out the new branch. 😺

[thibaudgg]

Great!

[rahearn]

the issue73 branch seems to fix everything I was seeing on sunaku/tork#43, both with and without rb-fsevent included

[thibaudgg]

Great, 0.7.0 released.
