85 * Untracked cache
86 *
87 * The following inputs are sufficient to determine what files in a
88 * directory are excluded:
89 *
90 * - The list of files and directories of the directory in question
91 * - The $GIT_DIR/index
92 * - dir_struct flags
93 * - The content of $GIT_DIR/info/exclude
94 * - The content of core.excludesfile
95 * - The content (or the lack) of .gitignore of all parent directories
96 * from $GIT_WORK_TREE
97 * - The check_only flag in read_directory_recursive (for
98 * DIR_HIDE_EMPTY_DIRECTORIES)
99 *
100 * The first input can be checked using directory mtime. In many
101 * filesystems, directory mtime (stat_data field) is updated when its
102 * files or direct subdirs are added or removed.
103 *
104 * The second one can be hooked from cache_tree_invalidate_path().
105 * Whenever a file (or a submodule) is added or removed from a
106 * directory, we invalidate that directory.
107 *
108 * The remaining inputs are easy, their SHA-1 could be used to verify
109 * their contents (exclude_sha1[], info_exclude_sha1[] and
110 * excludes_file_sha1[])
