Double events

[larzconwell]

On Linux 64bit, I'm getting double events on all events. I'm not sure if other platforms are problematic.

Here's the code that I used to test:

package main

import (
    "fmt"
    "github.com/howeyc/fsnotify"
    "os"
)

func main() {
    watcher, err := fsnotify.NewWatcher()
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    err = watcher.WatchFlags("/home/larz/Desktop/test.go", fsnotify.FSN_MODIFY)
    if err != nil {
        fmt.Println(err)
        os.Exit(1)
    }

    for {
        select {
        case event := <-watcher.Event:
            fmt.Println(event)
        case err := <-watcher.Error:
            fmt.Println(err)
            os.Exit(1)
        }
    }
}

Here's the output while running:

%:Desktop ⵗ go run test.go                                                 
"/home/larz/Desktop/test.go": MODIFY
"/home/larz/Desktop/test.go": MODIFY 

I only modified it once, so I'm not sure why it would be doing it twice.

I'm not sure I can fix the issue as all I have at the moment are 32bit Linux machines to test on.

But, what I did notice is that when running your test and doing and echo (echo "bam" >> test.go) created 1 event, but using a text editor (vi and :wq) created 2. Perhaps text editors do an attribute change as well as a modify?

I'm not sure what's going on, could you provide more information?

Ah I did the same test doing echo "sdfsdf" >> test.go and it only triggered one event.

I think editors are doing an extra modification then.

I think this can be closed as it isn't an actual bug just something with editors. Yeah?
