Vicent Marti 99baacfb 2011-03-21T19:27:45 Fix MSVC warnings
Vicent Marti 72a3fe42 2011-03-18T19:38:49 I broke your bindings Hey. Apologies in advance -- I broke your bindings. This is a major commit that includes a long-overdue redesign of the whole object-database structure. This is expected to be the last major external API redesign of the library until the first non-alpha release. Please get your bindings up to date with these changes. They will be included in the next minor release. Sorry again! Major features include: - Real caching and refcounting on parsed objects - Real caching and refcounting on objects read from the ODB - Streaming writes & reads from the ODB - Single-method writes for all object types - The external API is now partially thread-safe The speed increases are significant in all aspects, specially when reading an object several times from the ODB (revwalking) and when writing big objects to the ODB. Here's a full changelog for the external API: blob.h ------ - Remove `git_blob_new` - Remove `git_blob_set_rawcontent` - Remove `git_blob_set_rawcontent_fromfile` - Rename `git_blob_writefile` -> `git_blob_create_fromfile` - Change `git_blob_create_fromfile`: The `path` argument is now relative to the repository's working dir - Add `git_blob_create_frombuffer` commit.h -------- - Remove `git_commit_new` - Remove `git_commit_add_parent` - Remove `git_commit_set_message` - Remove `git_commit_set_committer` - Remove `git_commit_set_author` - Remove `git_commit_set_tree` - Add `git_commit_create` - Add `git_commit_create_v` - Add `git_commit_create_o` - Add `git_commit_create_ov` tag.h ----- - Remove `git_tag_new` - Remove `git_tag_set_target` - Remove `git_tag_set_name` - Remove `git_tag_set_tagger` - Remove `git_tag_set_message` - Add `git_tag_create` - Add `git_tag_create_o` tree.h ------ - Change `git_tree_entry_2object`: New signature is `(git_object **object_out, git_repository *repo, git_tree_entry *entry)` - Remove `git_tree_new` - Remove `git_tree_add_entry` - Remove `git_tree_remove_entry_byindex` - Remove `git_tree_remove_entry_byname` - Remove `git_tree_clearentries` - Remove `git_tree_entry_set_id` - Remove `git_tree_entry_set_name` - Remove `git_tree_entry_set_attributes` object.h ------------ - Remove `git_object_new - Remove `git_object_write` - Change `git_object_close`: This method is now *mandatory*. Not closing an object causes a memory leak. odb.h ----- - Remove type `git_rawobj` - Remove `git_rawobj_close` - Rename `git_rawobj_hash` -> `git_odb_hash` - Change `git_odb_hash`: New signature is `(git_oid *id, const void *data, size_t len, git_otype type)` - Add type `git_odb_object` - Add `git_odb_object_close` - Change `git_odb_read`: New signature is `(git_odb_object **out, git_odb *db, const git_oid *id)` - Change `git_odb_read_header`: New signature is `(size_t *len_p, git_otype *type_p, git_odb *db, const git_oid *id)` - Remove `git_odb_write` - Add `git_odb_open_wstream` - Add `git_odb_open_rstream` odb_backend.h ------------- - Change type `git_odb_backend`: New internal signatures are as follows int (* read)(void **, size_t *, git_otype *, struct git_odb_backend *, const git_oid *) int (* read_header)(size_t *, git_otype *, struct git_odb_backend *, const git_oid *) int (* writestream)(struct git_odb_stream **, struct git_odb_backend *, size_t, git_otype) int (* readstream)( struct git_odb_stream **, struct git_odb_backend *, const git_oid *) - Add type `git_odb_stream` - Add enum `git_odb_streammode` Signed-off-by: Vicent Marti <tanoku@gmail.com>

Vicent Marti b5c5f0f8 2011-03-16T23:59:09 Fix headers for the new Revision Walker The "oid.h" header is now included instead of "object.h". The old "revwalk.h" header has been removed; it was empty.
Vicent Marti 7341bf87 2011-03-16T23:13:28 Refs are now always in-sync on disk
Vicent Marti 9f81a37a 2011-03-16T23:02:31 Define NO_GZIP in zconf.h instead of at compile time
Vicent Marti 36aaf1ff 2011-03-16T01:53:25 Change the Revwalk reset behavior to the old version The `reset` call now removes the pushed commits so we can reuse the revwalker. The API documentation has been updated with the details.
Vicent Marti 8613d4a9 2011-03-16T01:10:40 Fix signature in `git_repository_gc` The method returns an int with the amount of objects free'd
Vicent Marti 54a1b36c 2011-03-16T01:07:06 Export `git_repository_gc` properly One of my brainfarts made me export it as `git_repository_close` instead of GC. Duh.
Vicent Marti 955f9ae9 2011-03-16T01:06:15 Export `git_strarray_free` instead of inlining That way non-C bindings can use it.
Vicent Marti 36b31329 2011-03-16T01:04:17 Properly free commit a commit list in revwalk The commit list was not being properly free'd when a walk was stopped halfway through.

Vicent Marti 434bedcd 2011-03-15T19:46:38 Fix compilation warnings in ZLib (MSVC) Yes, we are changing the Zlib code. This is dangerous and uncool. Fortunately, these are just some implicit casts.

Vicent Marti ab6a3d3d 2011-03-15T03:25:44 Add ZLib as a built-in dependency I don't know if this is good or bad. This lets libgit2 compile cleanly on any platforms without any external dependencies, but adds a little bit of bloat... Let's test this out and see what happens.
Ben Noordhuis 1ee32c6d 2011-03-14T00:33:45 Add test case for issue GH-86
Ben Noordhuis bd1aa741 2011-03-14T00:07:37 git_object_lookup() should also check the type if the object comes from the cache
Vicent Marti 7c8a7b91 2011-03-15T02:45:49 Skip the optional header in packed-refs files
Vicent Marti 7064938b 2011-03-14T23:55:32 libgit2 version 0.10.0, "very disco" A version *so* awesome that needs 2 version bumps AND a codename. Major features: - New internal garbage collection (harder) - Pack backend rewritten from scratch (better) - Revision walker rewritten from scratch (faster) - New object interdependency system (stronger) - Unique OID shortener - Reference listing In honor of one heck of a music album, released ten years ago, yesterday.
Vicent Marti 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.
Vicent Marti 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.
Vicent Marti 58d06cf1 2011-03-10T01:06:24 Rewrite the Pack backend The new pack backend is an adaptation of the original git.git code in `sha1_file.c`. It's slightly faster than the previous version and severely less memory-hungry. The call-stack of a normal pack backend query has been properly documented in the top of the header for future reference. And by properly I mean with ASCII diagrams 'n shit.
Vicent Marti 71db842f 2011-03-08T14:57:03 Rewrite the Revision Walker The new revision walker uses an internal Commit object storage system, custom memory allocator and much improved topological and time sorting algorithms. It's about 20x times faster than the previous implementation when browsing big repositories. The following external API calls have changed: `git_revwalk_next` returns an OID instead of a full commit object. The initial call to `git_revwalk_next` is no longer blocking when iterating through a repo with a time-sorting mode. Iterating with Topological or inverted modes still makes the initial call blocking to preprocess the commit list, but this block should be mostly unnoticeable on most repositories (topological preprocessing times at 0.3s on the git.git repo). `git_revwalk_push` and `git_revwalk_hide` now take an OID instead of a full commit object.
Vicent Marti 26022f07 2011-03-05T23:54:49 Add `git_oid_shorten` (unique OID minimzer) Set of methods to find the minimal-length to uniquely identify every OID in a list. Useful for GUI applications, commit logs and so on. Includes stress test. Signed-off-by: Vicent Marti <tanoku@gmail.com>

Vicent Marti 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.

Vicent Marti 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>

Vicent Marti 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).
