The note tree structure allows for non-note entries to coexist with note entries in a notes tree. Although we certainly expect there to be very few non-notes in a notes tree, we should still support them to a certain degree. This patch teaches the notes code to preserve non-notes when updating the notes tree with write_notes_tree(). Non-notes are not affected by fanout restructuring. For non-notes to be handled correctly, we can no longer allow subtree entries that do not match the fanout structure produced by the notes code itself. This means that fanouts like 4/36, 6/34, 8/32, 4/4/32, etc. are no longer recognized as note subtrees; only 2-based fanouts are allowed (2/38, 2/2/36, 2/2/2/34, etc.). Since the notes code has never at any point _produced_ non-2-based fanouts, it is highly unlikely that this change will cause problems for anyone. The patch also adds some tests verifying the correct handling of non-notes in a notes tree. Signed-off-by: Johan Herland <johan@herland.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
