Watchdog not able to identify permission change events on a file

[harshitkhanna]

I changed the permission of a file but no event was raised. Can we add support for permission/owner change events in watchdog?

I am using PollingObserver. Here is what I think is happening: PollingEmitter uses DirectorySnapshotDiff. DirectorySnapshotDiff considers modified files to be only those whose mtime changes. But changing permission (and hence metadata) doesnot change mtime. Should we add check for permission change as well?

I think along with mtime, we should also check difference in ctime (https://docs.python.org/3.8/library/stat.html) This will give the modified event even on file metadata change event.
