on('created') event is triggered twice

[hugohil]

Hi there !
Like the title say so, my "ceated" event gets triggered twice and I can't seem to figure out why.
Here is a sample code:

var root = "/home/me/myfolder",
    watch = require('watch');

watch.createMonitor(root, function (monitor) {
    monitor.on("created", function (path, stat) {
        console.log("created", path);
    });
});

When a new document is created, I see the log print twice.
Has anyone an idea on how could I fix this ?

I use setTimeout to avoid twice events.

I'm seeing the same issue. How can I use setTimeout to resolve it?

@MatthewCodes This is the issue in node repo: nodejs/node-v0.x-archive#1970

I create an array to store all changed files, and I filter out duplicated files by using changedFiles.indexOf().
But in timeout callback, I clear the array. So, you need to set an appropriate timeout value.

I'm using it to import xml files into a db. I used a que for the new files and then removed the duplicate before triggering the import that has throttling to limit the amount of memory used. Partial code below to give you an idea.

que.push(path);
que = uniqueArr(que); // return array of unique values
setTimeout(function() {
    _import();
}, timeout);
...
function _import () {
    if (!que.length || process_count >= process_max) { return; }
    var file = que.shift();
    ... // process file
    _import ();
}
