[PATCH 4/3] sha1_name: use bsearch_pack() in unique_in_pack()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Replace the custom binary search in unique_in_pack() with a call to
bsearch_pack().  This reduces code duplication and makes use of the
fan-out table of packs.

This is basically the same replacement as done by patch 3.  Speed is
less of a concern here -- at least I don't know a commonly used
command that needs to resolve lots of short hashes.
