From fc12261fea778cabd08dec707169cb88ecdbc647 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Sun, 14 Jul 2013 15:35:30 +0700 Subject: [PATCH] parse_pathspec: add PATHSPEC_PREFER_{CWD,FULL} flags MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We have two ways of dealing with empty pathspec: 1. limit it to current prefix 2. match the entire working directory Some commands go with #1, some #2. get_pathspec() and parse_pathspec() only support #1. Make parse_pathspec() reject empty pathspec by default. #1 and #2 can be specified via new flags. This makes it more expressive about default behavior at command level.
