Change event is only triggered twice when watching one file

[lonelywolf4git]

I want to watch file and only handle change event, but it is only triggered twice, when I change the watched file with third time, it can not handle change event, my code is here:

var chokidar = require('chokidar');
var path = require('path')
function registerFileChangeListener()
{
let testfile= path.join(__dirname, '../test.txt')
let watcher = chokidar.watch(testfile)
watcher.on('change',(path,stats)=>
{
console.log(path +' is changed')
})
}
registerFileChangeListener()

But it can fix this issue by adding
{
usePolling:true
}
I　am not sure why this happen.

Also cannot reproduce on Arch, Node 7.1.0, Chokidar 1.6.1.

Have you tried logging the raw events to see if chokidar is actually told of a change event? (and are you actually sure you're changing the file)

I have been hitting this error as of lately, I'm on v1.6.1 as well
The exact problem I'm hitting is that some files, with really long paths have their change events emitted twice. While files with shorter closer paths have their change event triggered only once.

My issue turned out to be an EMFILE one

Experiencing that here.
