From c0b13b21b8daa4bfb222e9c4d335c8b340c511a0 Mon Sep 17 00:00:00 2001 From: Michael Haggerty Date: Thu, 4 Aug 2011 06:36:14 +0200 Subject: [PATCH] Disallow the empty string as an attribute name Previously, it was possible to have a line like "file.txt =foo" in a .gitattribute file, after which an invocation like "git check-attr '' -- file.txt" would succeed. This patch disallows both constructs. Please note that any existing .gitattributes file that tries to set an empty attribute will now trigger the error message "error: : not a valid attribute name" whereas previously the nonsense was allowed through.
