This is a pure extraction from Nick Kallen's cache-money.


sudo gem install memcache-lock -s

(Note: If you already have the gemcutter gem installed, you can omit the -s part)


Instantiate the lock somewhere, like in an initializer if you're using rails. It needs a MemCache instance.

$cache ="/path/to/memcache/config")))
$lock  =$cache)

Then, wherever you'd like to lock a key, use it like this:

$lock.synchronize("some-memcache-key") do
  # stuff that needs synchronization in here

For more info, see lib/memcache-lock.rb. It's very straightforward to read.

Note on Patches/Pull Requests

  • Fork the project.

  • Make your feature addition or bug fix.

  • Add tests for it. This is important so I don't break it in a future version unintentionally.

  • Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but

    bump version in a commit by itself I can ignore when I pull)
  • Send me a pull request. Bonus points for topic branches.
