Vicent Marti d0323a5f 2011-06-01T21:25:56 short-oid: Cleanup
Marc Pegon ac2b94ad 2011-05-28T21:24:25 Added a GIT_OID_MINPREFIXLEN constant to define the minimum length allowed for oid prefixes (set to 4, like in git). Consequently updated some object lookup methods and their documentation.
Marc Pegon dd453c4d 2011-05-27T22:46:41 Added git.git sha1 lookup method to replace simple binary search in pack backend. Implemented find_unique_short_oid for pack backend, based on git sha1 lookup method; finding an object given its full oid is just a particular case of searching the unique object matching an oid prefix (short oid). Added git_odb_read_unique_short_oid, which iterates over all the backends to find and read the unique object matching the given oid prefix. Added a git_object_lookup_short_oid method to find the unique object in the repository matching a given oid prefix : it generalizes git_object_lookup which now does nothing but calls git_object_lookup_short_oid.

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 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.
