If we have a symlink "d" that points to a directory, we should not be able to remove "d/f". In the normal case, where "d/f" does not exist in the index, we already disallow this, as we only remove things that git knows about in the index. So for something like: ln -s /outside/repo foo git add foo git rm foo/bar we will properly produce an error (as there is no index entry for foo/bar). However, if there is an index entry for the path (e.g., because the movement is due to working tree changes that have not yet been reflected in the index), we will happily delete it, even though the path we delete from the filesystem is not the same as the path in the index. This patch documents that failure with a test. While this is a bug, it should not be possible to cause serious data loss with it. For any path that does not have an index entry, we will complain and bail. For a path which does have an index entry, we will do the usual up-to-date content check. So even if the deleted path in the filesystem is not the same as the one we are removing from the index, we do know that they at least have the same content, and that the content is included in HEAD. That means the worst case is not the accidental loss of content, but rather confusion by the user when a copy of a file another part of the tree is removed. Which makes this bug a minor and hard-to-trigger annoyance rather than a data-loss bug (and hence the fix can be saved for a rainy day when somebody feels like working on it).
