notes-cache: convert to struct object_id

2017-05-08T06:12:57Z

Convert as many instances of unsigned char [20] as possible. Update the callers of notes_cache_get and notes_cache_put to use the new interface. Among the functions updated are callers of lookup_commit_reference_gently, which we will soon convert. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

introduce notes-cache interface

2010-04-02T06:58:30Z

Notes provide a fast lookup mechanism for data keyed by sha1. This is ideal for caching certain operations, like textconv filters. This patch builds some infrastructure to make it simpler to use notes trees as caches. In particular, caches: 1. don't have arbitrary commit messages. They store a cache validity string in the commit, and clear the tree when the cache validity string changes. 2. don't keep any commit history. The accumulated history of a a cache is just useless cruft. 3. use a looser form of locking for ref updates. If two processes try to write to the cache simultaneously, it is OK if one overwrites the other, losing some changes. It's just a cache, so we will just end up with an extra miss.
