[Chrome] CallStack.callStack() missing function name

Hello there. I just noticed some inconsistent behavior when calling `CallStack.callStack()` across the browsers.

My code looks like that:

package sub;

import haxe.CallStack;

class TmpClass 
{
	public function new() 
	{
	}
	
	public function callMeMaybe():Void
	{
		trace(CallStack.toString(CallStack.callStack()));
	}
}

I'm creating an instance of this object and calling this function. I'm expecting to see class name and called function name in call stack and that indeed is the case*.

Firefox:


Called from module sub_TmpClass.prototype.callMeMaybe@http://localhost:2000/CallStack.js:349:39
Called from module Main.main@http://localhost:2000/CallStack.js:56:2
Called from module @http://localhost:2000/CallStack.js:354:1
Called from module @http://localhost:2000/CallStack.js:2:2
Called from module   CallStack.js:349:3

MS Edge:


Called from sub_TmpClass.prototype.callMeMaybe (http://localhost:2000/CallStack.js line 349)
Called from Main.main (http://localhost:2000/CallStack.js line 56)
Called from local function #null (http://localhost:2000/CallStack.js line 354)
Called from http://localhost:2000/CallStack.js line 2
CallStack.js (349,3)

* However....

Chrome:

CallStack.js:349 
Called from http://localhost:2000/CallStack.js line 349
Called from Main.main (http://localhost:2000/CallStack.js line 56)
Called from http://localhost:2000/CallStack.js line 354
Called from http://localhost:2000/CallStack.js line 355

There's no function or class name in Chrome's stack. Anyone know why is that? Is that default behavior in Chrome or maybe I disabled/turned off something by accident. Or anyone does know how to get it (if it's possible)?

Cheers,

Slawomir

Try jstack library http://lib.haxe.org/p/jstack/

This could also be fixed if this https://github.com/HaxeFoundation/haxe/issues/6085 is addressed, _probably_ ;P.

Anyway it would be worth investigating.

Thanks @Alexander, I decided to give jstack a try and results are um... a bit weird.

1st of all it was blowing up:

GET http://localhost:2000/null/CallStack.js.map 404 (Not Found)

Http Error #404

this is when I have .js file in same folder as .html. For some reason it's trying to look for a .map in `null` folder.

After putting js files into sub-folder it wasn't blowing up anymore and chrome is giving me:

Called from file:///C:/TMP/CallStack/src/sub/TmpClass.hx line 13
Called from file:///C:/TMP/CallStack/src/Main.hx line 10
Called from file:///C:/HaxeToolkit/haxe/lib/jstack/2,3,1/src/jstack/js/JStack.hx line 74
Called from http.onData (file:///C:/HaxeToolkit/haxe/lib/jstack/2,3,1/src/jstack/js/JStack.hx line 103)
Called from file:///C:/HaxeToolkit/haxe/std/haxe/Http.hx line 272

But that's pretty much the same, because I still can't see function name.

Another weird thing is that Firefox and Edge are showing me exactly same result as before. Any ideas why it's inconsistent across browsers?

Inconsitencies across browsers are all over the browsers ) It's web world.
I'd be thankfull if you create an issue in jstack repo with example code and environments setup.

However if original CallStack gives you no class/func info, then probably jstack won't help you.

I know that there's a lot of inconsistency all over the place in web world, but with a simple Stack Trace? Bit annoying :(
