Suggestions: LuaJIT ,dynamic libraries and other

[Chasel]

英文水平一般~勉强写一下吧

 

1.Use LuaJIT replace LUA Interpreter

https://github.com/paintdream/DontStarveLuaJIT

But this only on windows , we need linux too 

it can improve performance about 30% ~ 50%

 

2.dynamic libraries 

when i tried import a  dynamic library, It shows   " dynamic libraries not enabled; check your Lua installation"

Ubuntu平台：

[00:00:00]: DoLuaFile Error: error loading module 'library.luasql_mysql' from file 'scripts/library/luasql_mysql.so':
    dynamic libraries not enabled; check your Lua installation
LUA ERROR stack traceback:
        =[C] ?
        =[C] in function 'require'
        scripts/main.lua(83,1) in main chunk

Windows平台：

LUA ERROR stack traceback:
        =[C] ?
        =[C] in function 'require'
        scripts/main.lua(83,1) in main chunk

I want use .so or .dll to provide more functions

 

3. Crash

when i use "file:seek()"

the server crash immediately

 

e.g.

file, err = GLOBAL.io.open(filename, "w")
file:write(block)

file:seek()
