I recently upgraded to 0.25 from 0.23 and noticed there is a behavior
change to FollowTail with the SeekBack option. A 'SeekBack' => 0 is now
causing it to seek back instead of seeking to the EOF like one would
expect. The code was as follows
my $seek_back = ( (defined $params{SeekBack})
? $params{SeekBack}
: 4096
);
and has been changed to
my $seek_back = $params{SeekBack} || 4096;
so now if $params{SeekBack} is undefined or set to 0 it will make
$seek_back 4096. simple workaround on my part is to set SeekBack to -1.
simular situation exists with the PollInterval option, tho I dunno if 0 would
be a valid option for it.
