Crash in rb-inotify if file is not accessible is not handled gracefully #557

Open sebbASF opened 2 years ago

sebbASF commented 2 years ago

I tried watching a directory on Ubuntu (20.04). This has a link to a directory containing some files which are not accessible to the logged in user.

When such a file is encountered, listen crashes (see sample below). it would be better if it reported the issue and carried on - or at least provide the option to do so.
