From 34f3999206e8ea41b9e4cf48e30ab1149e01d8a5 Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Mon, 18 Jan 2010 22:55:07 +0100 Subject: [PATCH] grep: NUL terminate input from a file Internally "git grep" runs regexec(3) that expects its input string to be NUL terminated. When searching inside blob data, read_sha1_file() automatically gives such a buffer, but builtin-grep.c forgot to put the NUL at the end, even though it allocated enough space for it.
