Description

When changing the case of a filename on Windows, a deleted event is reported before the renamed event. The same happens for a directory.

The renamed event is also a bit misleading: it says the file was renamed to itself, with the same case for old and new path.

Steps to Reproduce

1. Start the watcher: watcher -v Dir
2. Rename Dir\Foo to Dir\foo

Expected behavior:

If Foo is a file:

renamed file: Dir\Foo -> Dir\foo

If Foo is a directory:

renamed directory: Dir\Foo -> Dir\foo

Actual behavior:

If Foo is a file:

deleted file: Dir\foo
renamed file: Dir\foo -> Dir\foo

If Foo is a directory:

deleted directory: Dir\foo
renamed directory: Dir\foo -> Dir\foo

Reproduces how often:

Always

Versions

Master

Additional Information

On windows, the filename is not case-sensitive, so if you do a stat on the old filename (Foo), it will give you the stats for the new filename (foo).
