Hi Dave,
Whilst working on File::Tail::Dir which uses File::ChangeNotify as the
underlying file watcher, I found that the presence of circular symbolic
links causes complete failure - instantiate_watcher() dies (in fact, the
problem is in File::Find - in File::Tail::Dir I ended up writing my own
recursion to get around File::Find).
Both File::ChangeNotify::Watcher::Default and Inotify exhibit the problem.
Failing test case is attached. Output is
$ perl fcn.t
1..2
ok 1 - use File::ChangeNotify;
# instantiate_watcher died with message:
# /tmp/FONXPafecs/input-circular2 is encountered a second time at
/usr/lib/perl5/5.10.0/File/Find.pm line 543.
#
# Watcher is a
not ok 2 - success if watcher defined without dying
# Failed test 'success if watcher defined without dying'
# at fcn.t line 33.
Regards,
