There was a problem hiding this comment.
Couldn't we rather change MarshalAsObjectId to let it handle the (handle.IsZero || handle.IsInvalid) logic? Or are there potential side-effects with this approach?

@whoisj Have you considered partial staging? This would allow you to only pick changes that you're willing to introduce. |

If the underlying directory structure has changed (deleted, renamed, etc) an invalid handle is correctly returned by Libgit2. Attempting to convert the invalid handle directly into an
