problem of jsb callback in multi-thread

cocos2d-x JavaScript
#1

Hi,everyone

is there a problem when JS_CallFunctionXXX into different thread?

i have read this two articles
http://my.oschina.net/u/816723/blog/138768
http://my.oschina.net/u/816723/blog/138949

as the second link, the JS_CallFunctionValue in onRequestCallback will generate a thread error in my case.

here is my js code and cpp code is same as the above articles

@
function callback()
{
cc.log(“in callback, arguments(”arguments.length“)=[”arguments“]”);
}

function main()
{
cc.log(“in jsb”);

var ret = hbb.CCPomelo.getInstance().connect(“127.0.01”, 3010);
if (ret != 0){
cc.log(“connect fail”);
return;
}

ret = hbb.CCPomelo.getInstance().request(“connector.entryHandler.entry”, “{sgi}”, this.callback);
if (ret != 0){
cc.log(“request fail”);
return;
}
}

main();

You should invoke js callback in the cocos2d thread.
This is the most simple way to do things.

But actually you may let js support multi-thread by creating more than one JSContext.
If you really want to do this, better check SpiderMonkey Docs in MDN.

thanks for your reply.
it works when I tried to invoke it in the cocos2d thread.
and you said that create a new JSContext maybe a better solution, but it’s a little diffcult to me (´Д｀)
i read the JS_SetContextThread/JS_ClearContextThread doc in MDN, but the both functions not included in jsapi.h
anyway i have a workaround so far, thank you

The Spidermonkey libraries built for cocos2d-x disabled thread-safe support. So probably, you should not invoke Spidermonkey API in another thread.
