Cannot move file to change case on case insensitive fs

[wmertens]

When calling move() it checks if the destination exists, and if it does it refuses to call rename. This means you can't change the case on a case-insensitive file system.

Fs-extra should check that the destination has the same inode before refusing to move.

node-fs-extra/lib/move/move.js

Line 41 in 40c3d68

if (destExists) return cb(new Error('dest already exists.'))

@wmertens can you provide us with repro test case please?

[wmertens]

The test itself is really simple: try to rename a file from lowercase to uppercase, it will fail when executed on a case-insensitive fs. The question is, can your test suite simulate that?

@wmertens I finally found some time to dig into your case! So here is what I found:

1. I appreciate if you would respect our issue template and respond to 3 simple questions that would help us resolve YOUR issue faster!
2. If you are using the latest version of fs-extra, we actually check the inodes of src and dest (as well as other properties) to determine if src and dest are the same before moving! However I just realized that implementation doesn't support cases like yours (when you want to just change the case) and I am working on that!
3. We actually have a test file for cases like this, however again I just realized that those tests are broken for case-insensitive systems! Currently for case-insensitive systems those tests expect an error thrown however the corect behavior should allow users change the case for case-insensitive systems! and I am working on that too!
