app reloads when starting

[illume]

When starting the app, I see it load, and then reload about 2 seconds after. It's much quicker when not in developer mode, but it does still reload.

I tried this with current main, and also a previous release 0.24.1. I'm not sure how long it's been happening, and haven't bisected back further.

It's not such a problem because in release mode it's very quick and barely noticeable. In dev mode it's just slightly annoying (to me anyway).

I've looked a bit more into this. When starting the backend it will start watching for plugin changes. When it detects change it will send a X-Reload header to the frontend.

But it also happens just when starting backend for the first time. You can notice the following log in the backend output

 {"level":"info","source":"/home/dubenko/headlamp/backend/pkg/plugins/plugins.go","line":224,"time":"2024-08-01T12:23:23+02:00","message":"Sending reload plugins signal to frontend"}

I've traced it down to plugins.go file. It manually sends a fsevent for all files on the first run, I think this is the issue

func periodicallyWatchSubfolders(watcher *fsnotify.Watcher, path string, interval time.Duration) {
// ...
				// when a folder is added, send events for all the files in the folder
				entries, err := os.ReadDir(path)
				if err != nil {
					logger.Log(logger.LevelError, map[string]string{"path": path},
						err, "reading dir")

					return err
				}
				for _, entry := range entries {
					watcher.Events <- fsnotify.Event{Name: filepath.Join(path, entry.Name()), Op: fsnotify.Create}
				}
// ...
}
