It did so successfully. "Changes to be committed" states an interpretation consistent with that. Now it is entirely silly in my book to describe files as "renamed" that are actually empty and thus do not contain a single common byte. I would call that change description a bug or at least a "misfeature". git mv, however, did exactly what it was tasked to do and could not possibly do anything better since Git does, by design, not ever track file operations. > This is reproducible for me with "git version 2.3.0" on > NetBSD-7.99.5/amd64. > > I guess this happens because the checksums of the files are the same > and 'Makefile' is earlier when sorting, but since I explicitly told > "git mv" old and new name, I think that's a bug nevertheless. No. Git mv is just a convenience command for deleting one file and creating another one with the same contents. Git has no concept of file renames in its repository, so git mv cannot record anything there that could not be interpreted exactly like the commit info interpreted it. It's nonsensical and should in my opinion rather be stated as # Changes to be committed: # removed: a # new file: Makefile # new file: b But that's not the fault of Git mv. -- David Kastrup -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
