| Subject: | Message::Passing::Input::FileTail reacts very badly to EOF (e.g. tail process dies) |
If the tail process that Message::Passing::Input::FileTail is reading dies the AnyEvent->io
callback fires continuously sending a stream of undef messages into the message chain.
The effect isn't pretty :)
EOF needs to be detected and the command either restarted (with a warning and restart limit)
or the input stream disabled in some way (with a warning).
Perhaps a callback could be called to warn, make the decision, and return true (restart) false
(disable) or throw an exception. Then the module doesn't need to implement much logic.
