The function used to return NULL when asked to find the containing directory for a ref that does not exist, allowing the caller to omit iteration altogether. But a misconversion in an earlier change "refs.c: extract function search_for_subdir()" started returning the top-level directory entry, forcing callers to walk everything.

Instead of reading the whole directory of loose references the first time any are needed, only read them on demand, one directory at a time. Use a new ref_entry flag bit REF_INCOMPLETE to indicate that the entry represents a REF_DIR that hasn't been read yet. Whenever any entries from such a directory are needed, read all of the loose references from that directory.

Previously, the "dir" argument to get_ref_dir() was a pointer to the top-level ref_dir. Change the function to expect a pointer to the ref_dir corresponding to dirname. This allows entries to be added directly to dir, without having to recurse through the reference trie each time (i.e., we can use add_entry_to_dir() instead of add_ref()).

Store references hierarchically in a tree that matches the pseudo-directory structure of the reference names. Add a new kind of ref_entry (with flag REF_DIR) to represent a whole subdirectory of references. Sort ref_dirs one subdirectory at a time. NOTE: the dirs can now be sorted as a side-effect of other function calls. Therefore, it would be problematic to do something from a each_ref_fn callback that could provoke the sorting of a directory that is currently being iterated over (i.e., the directory containing the entry that is being processed or any of its parents). This is a bit far-fetched, because a directory is always sorted just before being iterated over. Therefore, read-only accesses cannot trigger the sorting of a directory whose iteration has already started. But if a callback function would add a reference to a parent directory of the reference in the iteration, then try to resolve a reference under that directory, a re-sort could be triggered and cause the iteration to work incorrectly. Nevertheless...add a comment in refs.h warning against modifications during iteration. Signed-off-by: NMichael Haggerty <mhagger@alum.mit.edu> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Keep track of how many entries at the beginning of a ref_array are already sorted. In sort_ref_array(), return early if the the array is already sorted (i.e., if no new references has been appended to the end of the list since the last call to sort_ref_array()). Sort ref_arrays only when needed, namely in search_ref_array() and in do_for_each_ref(). However, never call sort_ref_array() on the extra_refs, because extra_refs can contain multiple entries with the same name and because sort_ref_array() not only sorts, but de-dups its contents. This change is currently not useful, because entries are not added to ref_arrays after they are created. But in a moment they will be... Implementation note: we could store a binary "sorted" value instead of an integer, but storing the number of sorted entries leaves the way open for a couple of possible future optimizations: * In sort_ref_array(), sort *only* the unsorted entries, then merge them with the sorted entries. This should be faster if most of the entries are already sorted. * Teach search_ref_array() to do a binary search of any sorted entries, and if unsuccessful do a linear search of any unsorted entries. This would avoid the need to sort the list every time that search_ref_array() is called, and (given some intelligence about how often to sort) could significantly improve the speed in certain hypothetical usage patterns.

resolve_ref() may return a pointer to a shared buffer and can be overwritten by the next resolve_ref() calls. Callers need to pay attention, not to keep the pointer when the next call happens. Rename with "_unsafe" suffix to warn developers (or reviewers) before introducing new call sites.
