Memory usage problems

[Florian Mounier <paradoxxx zero gmail com>]

Hi!

I have  written a gnome shell extension that displays system infos (http://github.com/paradoxxxzero/gnome-shell-system-monitor-applet).

I am having a hard time figuring out why when my extension is running, gnome shell memory usage is going crazy.

So I isolated this script that runs with gjs and uses a lot of memory:

/* -*- mode: js2; js2-basic-offset: 4; indent-tabs-mode: nil -*- */

const GLib = imports.gi.GLib;

const Mainloop = imports.mainloop;

const Lang = imports.lang;

function Mem_State() {

    this._init();

}

Mem_State.prototype = {

    _init: function() {

        this.update();

    },

    update: function() {

        let meminfo_lines = GLib.file_get_contents('/proc/meminfo')[1].split("\n");

        for(let i = 0 ; i < meminfo_lines.length ; i++) {

            let line = meminfo_lines[i].replace(/ +/g, " ").split(" ");

            switch(line[0]) {

            case "MemFree:":

                this.mem_free = line[1];

                break;

            }

        }

    }

};

function SystemMonitor() {

    this._init.apply(this, arguments);

}

SystemMonitor.prototype = {

    memory: {

        state: new Mem_State(),

        update: function () {

            this.memory.state.update();

            log("Free mem: " + this.memory.state.mem_free + " kB");

        }

    },

    _init: function() {

        let n = 0;

        this.timeout = Mainloop.timeout_add(

            5,

            Lang.bind(this, function () {

                          Lang.bind(this, this.memory.update)();

                          if(n++ > 100000)

                              Mainloop.quit('testMainloop');

                          return true;

                      }));

    }

};

new SystemMonitor();

Mainloop.run('testMainloop');

log('done');

If somebody can tell me what I am doing wrong, I would be very grateful.

Best regards
