MasterLock is a Ruby library for interprocess locking using Redis. Critical sections of code can be wrapped in a MasterLock block that ensures only one thread will run the code at a time. The locks are resilient to process failures by expiring after the thread obtaining them dies.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install master_lock
def perform_safe_operation .("perform_safe_operation") do # Code executes within locked context end end # Call MasterLock.start when your application boots up. # This starts a background thread to prevent locks from expiring. .
See documentation for advanced usage.
