From ae36bdcf5147b1b54de852eda111ad76a3040726 Mon Sep 17 00:00:00 2001 From: Steffen Prohaska Date: Sun, 11 Nov 2007 15:01:47 +0100 Subject: [PATCH] push: use same rules as git-rev-parse to resolve refspecs This commit changes the rules for resolving refspecs to match the rules for resolving refs in rev-parse. git-rev-parse uses clear rules to resolve a short ref to its full name, which are well documented. The rules for resolving refspecs documented in git-send-pack were less strict and harder to understand. This commit replaces them by the rules of git-rev-parse. The unified rules are easier to understand and better resolve ambiguous cases. You can now push from a repository containing several branches ending on the same short name. Note, this may break existing setups. For example, "master" will no longer resolve to "origin/master" even when there is no other "master" elsewhere.
