stuck in a reload loop

What happened?

In taskiq/cli/watcher.py, only the event types "opened" and "closed" were ignored. The "closed_no_write" event triggered an endless loop.

this is code:

class FileWatcher:  # pragma: no cover
    """Filewatcher that watches for filesystem changes."""
    ...
    def dispatch(self, event: FileSystemEvent) -> None:
        """
        React to event.

        This function checks whether we need to
        react to event and calls callback if we do.

        :param event: incoming fs event.
        """
        if event.is_directory:
            return
        if event.event_type in {"opened", "closed"}:
            return
        if ".git" in event.src_path:
            return
        try:
            if self.gitignore and self.gitignore(event.src_path):
                return
        except Exception as exc:
            logger.info(
                f"Cannot check path `{event.src_path!r}` in gitignore. Cause: {exc}",
            )
            return

        logger.debug(f"File changed. Event: {event}")
        self.callback(**self.callback_kwargs)

Perhaps adding an environment variable TASKIQ_RELOAD_IGNORE_EVENT_TYPE would be a good idea.

I am looking at the same issue. For me it is close no write events on __pycache__ files which live under my monitored folders.
I am getting around this for now by monkey patching the FileWatcher dispatch method.

Okay. Seems like like something has changed in the way we watch for files. Maybe lib update.

As a workaround you can add --reload-dir {project_dir}. This workaround will solve your issue. But I still need to look into it to resolve this problem without any arguments.
