Re: Req. Info - ts_lua

Here is a small example of using ts_lua as a global plugin. please make
sure you a line of "tslua.so /home/kichan/main.lua" in plugin.config and
the content of main.lua is as below.

ts.add_package_cpath('/home/kichan/lib/?.so')
ts.add_package_path('/home/kichan/lualib/?.lua;/home/kichan/lualib/socket/?.lua')

local redis = require 'redis'
local client = redis.connect('127.0.0.1', 6379)

function do_global_send_response()
  local response = client:ping()
  local value = client:get('mykey')
  ts.client_response.header['X-Redis-Ping'] = tostring(response)
  ts.client_response.header['X-Redis-MyKey'] = value
end

Please note
1) I have a local redis and I set a "mykey" already beforehand
2) I downloaded and compiled luasocket and redis-lua and put all "so" into
/home/kichan/lib/ and all lua files from them into /home/kichan/lualib/

Thanks.

Kit

Hi,
can you share with us some lines of code / examples?

Also we need to be careful in these use cases as well since the thread can
be blocked by the usage of the resource if we are not careful.
And perfomrnace will be affected.

Thanks.

I tried LuaSocket and redis-lua and I was able to define the
client/resources globally and use it inside the hooks.
But if you encounter any strange things, please feel free to answer us
questions here.

Also I have filed TS-3224 and TS-3225 for the fix and enhancement I am
planning to commit soon.

Thanks.

Hi,
I mean tcp sockets for external resources such as messaging systems (hornetq), db (redis) or others, the can be initiated, shared, controlled and used directly by lua.

RE: Req. Info - ts_lua

[Luca Rea <lu...@contactlab.com>]

Hi,
Using lua does is possible to define and initiate some global shared resources (eg. tcp sockets) then call and control them in other hooks?
