box: introduce Lua persistent functions
Kirill Shcherbatov authored 
Closes #4182
Needed for #1260

@TarantoolBot document
Title: Persistent Lua functions

Now Tarantool supports 'persistent' Lua functions.
Such functions are stored in snapshot and are available after
restart.
To create a persistent Lua function, specify a function body
in box.schema.func.create call:
e.g. body = "function(a, b) return a + b end"

A Lua persistent function may be 'sandboxed'. The 'sandboxed'
function is executed in isolated environment:
  a. only limited set of Lua functions and modules are available:
    -assert -error -pairs -ipairs -next -pcall -xpcall -type
    -print -select -string -tonumber -tostring -unpack -math -utf8;
  b. global variables are forbidden

Finally, the new 'is_deterministic' flag allows to mark a
registered function as deterministic, i.e. the function that
can produce only one result for a given list of parameters.

The new box.schema.func.create interface is:
box.schema.func.create('funcname', <setuid = true|FALSE>,
	<if_not_exists = true|FALSE>, <language = LUA|c>,
	<body = string ('')>, <is_deterministic = true|FALSE>,
	<is_sandboxed = true|FALSE>, <comment = string ('')>)

Example:
lua_code = [[function(a, b) return a + b end]]
box.schema.func.create('sum', {body = lua_code,
		is_deterministic = true, is_sandboxed = true})
box.func.sum
---
- is_sandboxed: true
  is_deterministic: true
  id: 2
  setuid: false
  body: function(a, b) return a + b end
  name: sum
  language: LUA
...
box.func.sum:call({1, 3})

Tarantool is an in-memory database and application server.

Key features of the application server:

  • 100% compatible drop-in replacement for Lua 5.1, based on LuaJIT 2.1. Simply use #!/usr/bin/tarantool instead of #!/usr/bin/lua in your script.
  • full support for Lua modules and a rich set of own modules, including cooperative multitasking, non-blocking I/O, access to external databases, etc

Key features of the database:

  • ANSI SQL, including views, joins, referential and check constraints
  • MsgPack data format and MsgPack based client-server protocol
  • two data engines: 100% in-memory with optional persistence and an own implementation of LSM-tree, to use with large data sets
  • multiple index types: HASH, TREE, RTREE, BITSET
  • asynchronous master-master replication
  • authentication and access control
  • the database is just a C extension to the application server and can be turned off

Supported platforms are Linux/x86 and FreeBSD/x86, Mac OS X.

Tarantool is ideal for data-enriched components of scalable Web architecture: queue servers, caches, stateful Web applications.

To download and install Tarantool as a binary package for your OS, please visit https://tarantool.io/en/download/.

To build Tarantool from source, see detailed instructions in the Tarantool documentation at https://tarantool.io/en/doc/2.1/dev_guide/building_from_source/.

Please report bugs at https://github.com/tarantool/tarantool/issues We also warmly welcome your feedback in the discussion mailing list, tarantool@googlegroups.com.

Thank you for your interest in Tarantool!
