From 55c61688ea1e41f4a8c26f957bf1bc43cd39ed97 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Fri, 12 Oct 2012 17:49:38 +0700 Subject: grep: stop looking at random places for .gitattributes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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", and Git looks for .gitattributes in the (non-existent but exploitable) path "rev:path" instead of "path". This patch passes real paths down to grep_source_load_driver() when: - grep on work tree - grep on the index - grep a commit (or a tag if it points to a commit) so that these cases look up .gitattributes at proper paths. .gitattributes lookup is disabled in all other cases.
