    using luasocket in a luascript

    in Enemy Territory Modding

    Posted

    Since I got this running now, I wanted to share on how to do it.

     

    u need https://github.com/siffiejoe/lua-moon/blob/master/examples/sofix.c compiled as shared Object with

    -DMOON_DLFIX_LIBNAME=/path/to/silent/qagame.mp.i386.so

     

    example: gcc -DMOON_DLFIX_LIBNAME='"/home/gs/wolfet/silent/qagame.mp.i386.so"' -m32 -Wall -Wextra -I.. -fpic -shared -Os -o sofix.so sofix.c

     

    Luasocket (precompiled for 32bit): https://ptpb.pw/gyb_.zip

     

    Copas: https://github.com/keplerproject/copas/tree/master/src

     

    copy/extract luasocket, sofix.so and copas to: silent/lualibs/

     

    after that create your luamodule. example:

    require('sofix') -- needs to be required before any other C based module

local copas = require('copas')
local asynchttp = require('copas.http').request

-- random callback
-- makes http request at every player connect (probably not what u wanna do)
function et_ClientConnect(clientNum, firstTime, isBot)
    copas.addthread(function()
        local body, c, h = asynchttp('http://example.org/')
        if c ~= 200 then
            et.G_LogPrint(("HTTP Error: %d"):format(c))
            return
        end
        -- use body and headers here. eg:
        et.G_LogPrint(body)
    end)
end

-- "Using gameloop as event loop"
function et_RunFrame(levelTime)
    if levelTime % 500 ~= 0 then
        return
    end
    copas.step()
end

    I am currently using a structure like that and haven't experienced any lags till now.

    having threads in lua should not be a problem, since u can just bind a C module anyway.

     

    But I would like to return a ~= nil value based on the result of the request in the et_ClientConnect callback.  how would I do that? I mean even if I fork the networking into a seperate thread, the function would still have to wait for that thread to finish, so I could return sth. I almost think that this would not be possible.

     

    So probably just always return nil and then kick based on the result.

     

    Still, this could be done more beautifully like calling every callback in its own thread and collecting the return values in an array. when all callbacks are finished, iterate over the results instead of calling the callbacks in a loop.

    So I got everything working now.

     

    One problem though,

     

    using luasocket http is blocking.

     

    Since I am using this in et_clientConnect (not always though) everytime I do the http request the server lags until the request has finished. I return nil or a string based on the result of the request.

     

    Is there any way I could make this callback nonblocking? (like let it execute for more than 1 server frame, the client has to wait for the result though)?

    Btw, luasockets work in the systemwide lua interpreter. (5.3.1 32bit)

    I'll get that panic before any lua module gets loaded.

    using luasocket in a luascript

    Am I blind or is there really no edit function for posts?

     

    well anyway,

     

    Now the module loads and works and stuff, BUT I cant do http requests.

    It always times out.

    tcpdump shows a successful TCP Handshake

    and after the timeout (eg 10s)

    I can see the TCP FIN "handshake"

     

    But I do NOT see any actual packages transmitted.

     

    any ideas?

     

    EDIT: hmm odd. I can edit this post, but not the other one.

     

    well after a bit of investigating I came to the conclusion, that while a socket:connect() works (tcp handshake and so on)

     

    nothing happens with a socket:send('some data')

     

    it just times out.

     

    So the problem is not related to the http.lua module. but already at the lowerlevel tcp module.

    Hi,

     

    I am currently trying to get luasocket working in one of my luascripts.

     

    I got luasocket compiled against the 32bit liblua53 and moved it to silent/lualibs.

     

    I still got following problem though. It seems like silent lua extension does NOT reexport modules like lua_gettop

     

    I get: socket/core.so: undefined symbol: lua_gettop

     

    i found this: https://github.com/siffiejoe/lua-moon/

     

    I am not sure if I just failed to compile it correctly but after requireing sofix in my lua module I still get the same error. (the require works though.)

    What is KR and PRW?

    Maybe take a look at the TrueSkill Algorithm by microsoft for upcoming versions. TrueSkill also provides logic for matchmaking and balancing teams.
