Hi Jon, i'm really curious if this ever finds its way to you. been using File::Tail::Dir for a couple of days now and i really like it. thanks so much for making it public! one thing. it seems when i set $tailer->runnning(0) the module will eventually end its loop and call _stop_watchdog. it appears that method is missing. figured you might want to know about it. i've put an eval {} around the watch_files() and just exit when the error is caught. I'm thinking there isn't much of any cleanup to do since the state was saved prior to the _stop_watchdog call. anyway. that's it. and thanks again for the module. cheers, stephen sprague spragues@gmail.com

Thanks so much Jon. The way you're storing state is really a bang up job and pretty hard-core. Its looks like you meant business when you started off on this! :) I'm using it to feed Kafka (LinkedIn's opensource pub/sub app) and so far things look great! Thanks again.

Hi Jon, This isn't a bug but it would still be great to get your feedback. Here's my current dilemma. How can i exit the tailing process, watch_files(), programmatically from my code? I know about your running(0) method but its kinda hard to call it when my process_lines method isn't invoked. The simple case is an empty file. My callback is never called so i can't do anything to stop your module's event loop - from what i can tell anyway. In my case, if i don't get any records for 1 minute i can assume no more records will ever be written to the file i'm tailing - so i'd like to exit gracefully. I was thinking maybe a heartbeat type of callback could be employed in your module that you could call when in a wait mode. Then execution comes back to my code. just a thought. Anyhoo, what would you recommend in this case? thanks, stephen sprague spragues@gmail.com On Fri, Sep 27, 2013 at 8:52 AM, Stephen Sprague <spragues@gmail.com> wrote: Show quoted text

Hi Stephen, The built-in watchdog will cater for this situation. If you set autostate_delay to 60 and enable autostate, the watchdog will cause the watch_files loop to be interrupted at least every 60 seconds and running(0) will be recognised. It will also save state. Arguably the autostate and loop checking functions should be separated - but that's the way it works at the moment.
