vkiryukhin / vkthread Goto Github PK

Hi,

I was just trying your nice piece of work, and I got into this:

TypeError: Converting circular structure to JSON
at Object.stringify (native)
at Object.JSONfn.stringify (http://rails.lan:5000/libs/vkthread/0.51.00/vkthread.js:32:15)

... while passing javascript Obj as arguments of a function. Is it even possibile in the first place? Everything works as expected passing numeric values.

Thanks,
Luca

Hi,

I wonder if it is possible to do AJAX calls with vkthread?

(With vanilla Worker, I can do postMessage inside the onreadystatechange handler, I'm not sure if it is possible to do something similar with this library.)

Thanks!

hello,
thanks for this awesome library, i have some work defined as :

function bytesToSize(bytes) {
            var sizes = ['Bytes', 'KB', 'MB', 'GB', 'TB'];
            if (bytes == 0) return '0 Byte';
            var i = parseInt(Math.floor(Math.log(bytes) / Math.log(1024)));
            return Math.round(bytes / Math.pow(1024, i), 2) + ' ' + sizes[i];
        };
        function computeCompletionSize(taskList) {
            var totalSize = doneSize = 0;
            for (var i = 0; i < taskList.length; i++) {
                console.log(taskList[i].taskFileSize);
                totalSize +=taskList[i].taskFileSize;
                //done size
                if (taskList[i].taskPercent === 100) {
                    doneSize += taskList[i].taskFileSize;
                    var elem = document.getElementById(taskList[i].taskId);
                    elem.parentNode.removeChild(elem);
                }
            }
            console.log(bytesToSize(doneSize) + " /" + bytesToSize(totalSize));
            return bytesToSize(doneSize) + " /" + bytesToSize(totalSize);
        }

called from:

var param = {
                    fn: computeCompletionSize,     // <-- function to run in a thread;
                    args: [taskList] // <-- function's arguments;
                };
                vkthread.exec(param).then(function (data) {
                    document.getElementById("prgsize").innerText = data;
                });

now i suppose the reason for error bytesToSize func not defined is due to it being on another thread, can you tell me how i can put this or call in same context/thread so it starts working without my code loosing modularity.
thanks

Hi , i need to ask you
how i can integrate it with my project

i added the package file (vkThread) but when i attempt to execute any method , it show me an exception
that Promise isn't defined!

this.path = 'http'+ err.split('http')[1].split('vkthread.js').slice(0,-1) + 'worker.js';

It's code not work for url with file:// protocol.

If you pass an object like the following

{
"name":"function",
"args":[]
}

through JSONfn.stringify and JSONfn.parse you will get a syntax error because it will try and eval the string "function" which will error.

updating JSONfn in vkthread.js

var JSONfn = {

/* this is a fragment of JSONfn plugin ( https://github.com/vkiryukhin/jsonfn ) */

stringify:function (obj) {
  return JSON.stringify(obj, function (key, value) {
    if (value instanceof Function || typeof value == 'function') {
      return '_nOiTcNuf_' + value.toString();
    }
    if (value instanceof RegExp) {
      return '_PxEgEr_' + value;
    }
    return value;
  });
}

};

and JSONfn in worker.js

var JSONfn = {
parse:function (str, date2obj) {
var iso8061 = date2obj ? /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:.\d*)?)Z$/ : false;
return JSON.parse(str, function (key, value) {
if (typeof value != 'string') return value;
if (value.length < 8) return value;
if (iso8061 && value.match(iso8061)) return new Date(value);
if (value.substring(0, 10) === 'nOiTcNuf') return eval('(' + value.slice(10) + ')');
if (value.substring(0, 8) === 'PxEgEr') return eval(value.slice(8));
return value;
});
}
};

like this negates the problem.

Feature Request

Problem:

Drop all bower usage in dev-environment to unify and simplify dependency management for developers by receiving all packages using npm/yarn.

Solution:

Would you mind publishing the package on npm? I wouldn't mind doing or managing updates and releases myself - but have no previous expertise on this - and npm terms state you mustn't confuse people about the authorship of the package. I think would you have to register and npm account, reference the original repo first - afterwards i think releasing versions etc. would be possible by pull request.

Tasks:

• Register npm account
• Register package
• Release initial version

Json.stringify throw an error when the function callsvkthread.execrecursively :

<script>
var recursionLevel=0;
var maxthreads=0;
var recursion = function(obj){
  for(var b in obj) { 
    if(typeof obj.hasOwnProperty !== 'undefined' && obj.hasOwnProperty(b)){
      if(typeof obj[b] === "string" && obj[b].indexOf("domains.google") == -1 && obj[b].indexOf("googrz.co.nz")>-1){
    alert(obj);
        obj[b] = obj[b].replace("googrz.co.nz", "googrz.co.in");
      }else if(typeof obj[b] === "object" && obj[b] && recursionLevel<150){ // call as an object "recursively"
        recursionLevel++;
        if(maxthreads<8) {
           maxthreads++;
           vkthread.exec(recursion,[obj[b]],function(data){maxthreads--;})
         } else
           recursion(obj[b]);
        recursionLevel--;
      }
    }
  }
}
recursion(window);
</script>

Hello!
Great library!

I have a quick question: does your library support multiple contexts?

Playing with your simple example, is there a way to make something like this work?

function Demo(str, max){
	this.str = str;
	this.max = max;
}
Demo.prototype.foo = function(){
	var ret, ix;
	for(ix=0;ix<this.max;ix++){
		ret = this.str.split(',').join('-');
	}
	return ret;
};
function Act(obj1,obj2){
  this.obj1 = obj1;
  this.obj2 = obj2;
}
Act.prototype.bar = function(){
   return String(this.obj1.max+this.obj1.max) + String(this.obj2.foo()) + String(this.obj1.foo()); // could be more complicated
};


var myDemo1 = new Demo('aaa,bbb,ccc',7e5);
var myDemo2 = new Demo('123,456,789',5);

var myAct = new Act(myDemo1,myDemo2);

var param = {
	    fn: myAct.bar,
	    context: myAct
    };

vkthread.exec(param).then(
    function(data){
	    console.log(data);
    }
);

( Does not work like this, see fiddle )
