Simplify cache API
Earlier, add_file_to_index() invalidated the path in the cache-tree but remove_file_from_cache() did not, and the user of the latter needed to invalidate the entry himself. This led to a few bugs due to missed invalidate calls already. This patch makes the management of cache-tree less error prone by making more invalidate calls from lower level cache API functions. The rules are: - If you are going to write the index, you should either maintain cache_tree correctly. - If you cannot, alternatively you can remove the entire cache_tree by calling cache_tree_free() before you call write_cache(). - When you modify the index, cache_tree_invalidate_path() should be called with the path you are modifying, to discard the entry from the cache-tree structure. - The following cache API functions exported from read-cache.c (and the macro whose names have "cache" instead of "index") automatically call cache_tree_invalidate_path() for you: - remove_file_from_index(); - add_file_to_index(); - add_index_entry(); You can modify the index bypassing the above API functions (e.g. find an existing cache entry from the index and modify it in place). You need to call cache_tree_invalidate_path() yourself in such a case. Signed-off-by: Junio C Hamano <gitster@pobox.com>
