Greetings dear monks,

I am using POE::Wheel::FollowTail to parse a number of log files written to one central logging server. Unfortunately these files include the epoch time in the file name and a rolled over at midnight. The name of the new file should be predictable, it is a base name plus the epoch seconds at midnight.

I plan to act on the ResetEvent that should be generated when the file is removed. Then I want to change FollowTails' internal file name with something like ...

sub reset_handler {
    my ($heap, $wheel_id) = @_[HEAP, ARG0 ];
    # I kept a ref to wheel under its ID in the heap
    my $wheel = $heap->{wheel}->{"wheel_$id"};
    my $SELF_FILENAME = $POE::Wheel::FollowTail::SELF_FILENAME();
    my $new_file = derive_new_name();
    $wheel->[$SELF_FILENAME] = $new_file;
    return;
}

when FollowTail tries to re-open the file it should pick up the new one. I think it should work with perhaps a little minor tweaking but is it sane to hook into internal details of FollowTail like this or is there a more sensible way to do this ?

Thanks for taking the time,
R.
