* Start on lua scripting * Implement evalsha, script load, script exists, and script flush * Type conversions from lua to resp/json. Refactor to make luastate and luascripts persistent in the controller. * Change controller.command and all underlying commands to return resp.Value. Serialize only during the ouput. * First stab at tile38 call from lua * Change tile38 into tile38.call in Lua * Property return errors from scripts * Minor refactoring. No locking on script run * Cleanup/refactoring * Create a pool of 5 lua states, allow for more as needed. Refactor. * Use safe map for scripts. Add a limit for max number of lua states. Refactor. * Refactor * Refactor script commands into atomic, read-only, and non-atomic classes. Proper locking for all three classes. Add tests for scripts * More tests for scripts * Properly escape newlines in lua-produced errors * Better test for readonly failure * Correctly convert ok/err messages between lua and resp. Add pcall, sha1hex, error_reply, status_reply functions to tile38 namespace in lua. * Add pcall test. Change writeErr to work with string argument * Make sure eval/evalsha never attempt to write AOF * Add eval-set and eval-get to benchmarks * Fix eval benchmark tests, add more * Improve benchmarks * Optimizations and refactoring. * Add lua memtest * Typo * Add dependency * golint fixes * gofmt fixes * Add scripting commands to the core/commands.json * Use ARGV for args inside lua
