      meir@redislabs.com authored
      Redis function unit is located inside functions.c
      and contains Redis Function implementation:
      1. FUNCTION commands:
        * FUNCTION CREATE
        * FCALL
        * FCALL_RO
        * FUNCTION DELETE
        * FUNCTION KILL
        * FUNCTION INFO
      2. Register engine
      
      In addition, this commit introduce the first engine

      Redis Functions - Moved invoke Lua code functionality to script_lua.c · f21dc38a
      meir@redislabs.com authored
      The functionality was moved to script_lua.c under
      callFunction function. Its purpose is to call the Lua
      function already located on the top of the Lua stack.
      
      Used the new function on eval.c to invoke Lua code.
      The function will also be used to invoke Lua
      code on the Lua engine.

      Redis Functions - Introduce script unit. · fc731bc6
      meir@redislabs.com authored
      Script unit is a new unit located on script.c.
      Its purpose is to provides an API for functions (and eval)
      to interact with Redis. Interaction includes mostly
      executing commands, but also functionalities like calling
      Redis back on long scripts or check if the script was killed.
      
      The interaction is done using a scriptRunCtx object that
      need to be created by the user and initialized using scriptPrepareForRun.
      
      Detailed list of functionalities expose by the unit:
      1. Calling commands (including all the validation checks such as
         acl, cluster, read only run, ...)
      2. Set Resp
      3. Set Replication method (AOF/REPLICATION/NONE)
      4. Call Redis back to on long running scripts to allow Redis reply
         to clients and perform script kill
      
      The commit introduce the new unit and uses it on eval commands to
      interact with Redis.

      meir@redislabs.com authored
      The following variable was renamed:
      1. lua_caller 			-> script_caller
      2. lua_time_limit 		-> script_time_limit
      3. lua_timedout 		-> script_timedout

      5. lua_disable_deny_script 	-> script_disable_deny_script
      6. in_eval			-> in_script
      
      The following variables was moved to lctx under eval.c
      1.  lua
      2.  lua_client
      3.  lua_cur_script
      4.  lua_scripts
      5.  lua_scripts_mem

      10. lua_repl
      11. lua_kill
      12. lua_time_start
      13. lua_time_snapshot
      
      This commit is in a low risk of introducing any issues and it
      is just moving varibales around and not changing any logic.

      Redis Functions - Move code to make review process easier. · 22aab1ce
      meir@redislabs.com authored
      This commit is only move code around without changing it.
      The reason behind this is to make review process easier
      by allowing the reviewer to simply ignore all code movements.
      
      changes:
      1. rename scripting.c to eval.c
      2. introduce and new file, script_lua.c, and move parts of Lua
         functionality to this new file. script_lua.c will eventually
         contains the shared code between legacy lua and lua engine.
      
      This commit does not compiled on purpose. Its only purpose is to move
      code and rename files.
