npool's Issues

segfault if thread function's last statement is console.log

Example thread function file:

module.exports = function() { this.work_method = function( data ) { console.log("WORKMETHOD"); } };

When executed via nPool.queueWork(...); it segfaults.

require an installed node module

Apparently it's not possible to load an installed module from within a work unit.
Here below an example, just to give an idea:

main file:

var nPool = require('npool');

nPool.loadFile(1, __dirname + '/test.js');
nPool.createThreadPool(20);

var unitOfWork = {
    workId:           uniqID(),
    fileKey:          1,
    workFunction:     "run",
    workParam:        {},
    callbackFunction: callbackFunction,
    callbackContext:  funcion () {}
};

// queue the unit of work
nPool.queueWork(unitOfWork);

test.js

var fs = require('fs');

This is the error generated:

{ message: 'Uncaught Error: Require::RequireFunction - File Name is invalid: fs',
  resourceName: 'test.js',
  lineNum: 1,
  sourceLine: 'var fs = require(\'fs\'),',
  stackTrace: 'Error: Require::RequireFunction - File Name is invalid: fs\n    at test.js:1:10' }

Is there any known workaround until the problem will be fixed?

Thank you

Update to nan v2.0.4

This currently breaks support for iojs v3.0.0 until complete.

https://travis-ci.org/inh3/nPool/jobs/60476730

I understand that you have to emulate require to work around it only being available on the main thread, but you you implement the http://nodejs.org/docs/v0.4.8/api/all.html#all_Together... algorithm so one can require dependencies like normal? This would also allow us to require dependencies that require other dependencies without having everything break.

Event Emitter interface for threads

Like in gogo lib, but with type support (not only toString() all arguments).

Code load support

Is it possiable to load code not only from file but

from strings, like pool.loadString('function () {}');
from defined functions, like pool.loadFunction(function () {}) (by function.toString() method maybe)

Thanks for your work!

webworker polyfill

dunno if this makes full sense but I think it might be interesting to polyfill the web worker API, that way I could use this with https://github.com/substack/webworkify

Node >= 0.11.x support?

I'm sure you have a lot on your plate and that it's not necessary a quick change, but I was wondering if there was any plans for supporting node > 0.10.x ?

I'd like to help if I can at some point, but I have to brush up on my C/C++ first :)
