File watcher doesn't work on mounted files on Docker (Windows host)

[casab]

I am running bacon --headless run-long on a docker dev container to hot reload. Container is using volume mounted from Windows host and bacon should be watching the files on that volume. Running on windows and running on linux works fine. But for some reason file watcher doesn't seem to work on this specific case.

I think bacon checks for the file changes by listening inotify events. Is there any option that uses polling instead that I have missed?

No, there's none today.

I checked out how notify-rs defines watchers. And how bacon uses notify. RecommendedWatcher fallsback to PollWatcher when the target is not available. Also it's advised to use PollWatcher in such cases; https://docs.rs/notify/latest/notify/#network-filesystems

I found similar issues around. Especially this;

notify-rs/notify#254

So, I tried modifying Watcher in src/watcher.rs. I have replaced RecommendedWatcher with PollWatcher, with this config;

Config::default()
                .with_poll_interval(Duration::from_secs(5))
                .with_compare_contents(true)

Still didn't work. I thought if I could be sure that PollWatcher works for every system. I could just add a new option like --poll <seconds`> or add some logic that checks for wsl. But, oh well...

I was also encountering this exact same problem with a mac host today.
