6b2a1941	2011-03-12T23:09:16	Fix the retarded object interdependency system It's no longer retarded. All object interdependencies are stored as OIDs instead of actual objects. This should be hundreds of times faster, specially on big repositories. Heck, who knows, maye it doesn't even segfault -- wouldn't that be awesome? What has changed on the API? `git_commit_parent`, `git_commit_tree`, `git_tag_target` now return their values through a pointer-to-pointer, and have an error code. `git_commit_set_tree` and `git_tag_set_target` now return an error code and may fail. `git_repository_free__no_gc` has been deprecated because it's stupid. Since there are no longer any interdependencies between objects, we don't need internal reference counting, and GC never fails or double-free's pointers. `git_object_close` now does a very sane thing: marks an object as unused. Closed objects will be eventually free'd from the object cache based on LRU. Please use `git_object_close` from the garbage collector `destroy` method on your bindings. It's 100% safe. `git_repository_gc` is a new method that forces a garbage collector pass through the repo, to free as many LRU objects as possible. This is useful if we are running out of memory.
00571828	2011-03-12T16:04:46	Add new method `git_reference_listall` Lists all the references in a repository. Listing may be filtered by reference type. This should applease Lord Clem.

8f90ced5	2011-03-03T19:55:48	Fix corner case in reference renaming Renaming a packed reference should not pack another reference which happens to be in both loose and pack state.
86d7e1ca	2011-02-28T12:46:13	Fix searching in git_vector We now store only one sorting callback that does entry comparison. This is used when sorting the entries using a quicksort, and when looking for a specific entry with the new search methods. The following search methods now exist: git_vector_search(vector, entry) git_vector_search2(vector, custom_search_callback, key) git_vector_bsearch(vector, entry) git_vector_bsearch2(vector, custom_search_callback, key) The sorting state of the vector is now stored internally.

aa2120e9	2011-02-10T15:08:00	Added git_reference__normalize_name() along with tests.
fc658755	2011-02-22T21:59:36	Rewrite git_hashtable internals The old hash table with chained buckets has been replaced by a new one using Cuckoo hashing, which offers guaranteed constant lookup times. This should improve speeds on most use cases, since hash tables in libgit2 are usually used as caches where the objects are stored once and queried several times. The Cuckoo hash implementation is based off the one in the Basekit library [1] for the IO language, but rewritten to support an arbritrary number of hashes. We currently use 3 to maximize the usage of the nodes pool. [1]: https://github.com/stevedekorte/basekit/blob/master/source/CHash.c Signed-off-by: Vicent Marti <tanoku@gmail.com>
817c2820	2011-02-21T17:05:16	Rewrite all file IO for more performance The new `git_filebuf` structure provides atomic high-performance writes to disk by using a write cache, and optionally a double-buffered scheme through a worker thread (not enabled yet). Writes can be done 3-layered, like in git.git (user code -> write cache -> disk), or 2-layered, by writing directly on the cache. This makes index writing considerably faster. The `git_filebuf` structure contains all the old functionality of `git_filelock` for atomic file writes and reads. The `git_filelock` structure has been removed. Additionally, the `git_filebuf` API allows to automatically hash (SHA1) all the data as it is written to disk (hashing is done smartly on big chunks to improve performance).

995f9c34	2011-02-09T12:43:19	Use the new git__joinpath to build paths in methods The `git__joinpath` function has been changed to use a statically allocated buffer; we assume the buffer to be 4096 bytes, because fuck you. The new method also supports an arbritrary number of paths to join, which may come in handy in the future. Some methods which were manually joining paths with `strcpy` now use the new function, namely those in `index.c` and `refs.c`. Based on Emeric Fermas' original patch, which was using the old `git__joinpath` because I'm stupid. Thanks! Signed-off-by: Vicent Marti <tanoku@gmail.com>

2f8a8ab2	2011-01-29T01:56:25	Refactor reference parsing code Several changes have been committed to allow the user to create in-memory references and write back to disk.

9282e921	2010-12-27T20:34:19	Merge nulltoken's reference parsing code All the commits have been squashed into a single one before refactoring the final code, to keep everything tidy. Individual commit messages are as follows: Added repository reference looking up functionality placeholder. Added basic reference database definition and caching infrastructure. Removed useless constant. Added GIT_EINVALIDREFNAME error and description. Added missing description for GIT_EBAREINDEX. Added GIT_EREFCORRUPTED error and description. Added GIT_ETOONESTEDSYMREF error and description. Added resolving of direct and symbolic references. Prepared the packed-refs parsing. Added parsing of the packed-refs file content. When no loose reference has been found, the full content of the packed-refs file is parsed. All of the new (i.e. not previously parsed as a loose reference) references are eagerly stored in the cached references storage. The method packed_reference_file__parse() is in deer need of some refactoring. :-) Extracted to a method the parsing of the peeled target of a tag. Extracted to a method the parsing of a standard packed ref. Fixed leaky removal of the cached references. Ensured that a previously parsed packed reference isn't returned if a more up-to-date loose reference exists. Enhanced documentation of git_repository_reference_lookup(). Moved some refs related constants from repository.c to refs.h. Made parsing of a packed tag reference more robust. Updated git_repository_reference_lookup() documentation. Added some references to the test repository. Added some tests covering tag references looking up. Added some tests covering symbolic and head references looking up. Added some tests covering packed references looking up.
