Subject: Re: git status always modifies index?

Message-ID: <5050d779-2981-6f06-49f7-0ecb4efb25b8@neulinger.org> (raw)
In-Reply-To: <20171122153028.olssotkcf3dd6ron@LykOS.localdomain>
What I'm meaning is - why does it need to write the index back out to disk?
From looking at the code in builtin/commit.c it looks like it takes a lock on the index, collects the status, and then
unconditionally rewrites the index file.
I'm proposing that the update_index_if_able call not actually be issued if it would result in a ownership change on the
underlying file - such as a simple case of root user or other privileged account issuing 'git status' in a directory.
I understand completely that it would be expected to be altered if the privileged user did a commit/add or any other
operation that was inherently a 'write' operation, but doesn't seem like status should be one of those cases.
