Subject: [PATCH 3/3] grep: stop looking at random places for .gitattributes
Date: Wed, 10 Oct 2012 18:34:54 +0700 [thread overview]
Message-ID: <1349868894-3579-4-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1349868894-3579-1-git-send-email-pclouds@gmail.com>
grep searches for .gitattributes using "name" field in struct
grep_source but that field is not real on-disk path name. For example,
"grep pattern rev" fills the field with "rev:path", which is
non-existent usually until somebody exploits it to drive git away.
attr does not support looking up .gitattributes from a tree object.
Making "git grep pattern <rev>" support .gitattributes could be a big
work. Just note in document what we support for now. The document
changes in this patch are to be reverted once support is in place.
