git notes merge: Initial implementation handling trivial merges only
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() - Junio C Hamano: fixup minor style issues Thanks-to: Stephen Boyd <bebarino@gmail.com> Thanks-to: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Thanks-to: Jonathan Nieder <jrnieder@gmail.com> Thanks-to: Junio C Hamano <gitster@pobox.com> Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
