From 75ef3f4a5cc69b21bc825ed0e739030d77a4f077 Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Tue, 9 Nov 2010 22:49:46 +0100 Subject: git notes merge: Initial implementation handling trivial merges only MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This initial implementation of 'git notes merge' only handles the trivial merge cases (i.e. where the merge is either a no-op, or a fast-forward). The patch includes testcases for these trivial merge cases. Future patches will extend the functionality of 'git notes merge'. This patch has been improved by the following contributions: - Stephen Boyd: Simplify argc logic - Stephen Boyd: Use test_commit - Ævar Arnfjörð Bjarmason: Don't use C99 comments. - Jonathan Nieder: Add constants for common verbosity values - Jonathan Nieder: Use trace_printf(...) instead of OUTPUT(o, 5, ...) - Jonathan Nieder: Remove extraneous show() function - Jonathan Nieder: Clarify handling of empty/missing notes ref in notes_merge() -
