I have added some small changes top the base class that allow:
(1) use of an extend method to extend a lock that is already owner by a specified ttl
(2) test if a lock with a given name is already taken
The extension mechanism is based on the specification in the original paper, and uses an in-DB Lua script to ensure atomicity.
I have also updated the CLI accordingly.
This is a small change, but adds a useful capability, enabling lock owners to poll and extend at regular intervals. I hope you think it adds to the library as is.
