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 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 f335b42c 2011-03-05T01:17:59 Fix segmentation fault when freeing a repository Disable garbage collection of cross-references to prevent double-freeing. Internal reference management is now done with a separate method. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 48c27f86 2011-02-28T16:51:17 Implement reference counting for git_objects All `git_object` instances looked up from the repository are reference counted. User is expected to use the new `git_object_close` when an object is no longer needed to force freeing it. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 5de079b8 2011-02-28T12:12:26 Change the object creation/lookup API The methods previously known as git_repository_lookup git_repository_newobject git_repository_lookup_ref are now part of their respective namespaces: git_object_lookup git_object_new git_reference_lookup This makes the API more consistent with the new references API.

Vicent Marti 638c2ca4 2010-12-18T02:10:25 Rename 'git_person' to 'git_signature' The new signature struct is public, and contains information about the timezone offset. Must be free'd manually by the user. Signed-off-by: Vicent Marti <tanoku@gmail.com>
nulltoken 13710f1e 2010-12-10T16:30:06 Added timezone offset parsing and outputting.
Vicent Marti 44908fe7 2010-12-06T23:03:16 Change the library include file Libgit2 is now officially include as #include "<git2.h>" or indidividual files may be included as #include <git2/index.h> Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti d12299fe 2010-12-03T22:22:10 Change include structure for the project The maze with include dependencies has been fixed. There is now a global include: #include <git.h> The git_odb_backend API has been exposed. Signed-off-by: Vicent Marti <tanoku@gmail.com>

Vicent Marti 6b1eab39 2010-11-23T14:36:31 Fix MSVC warnings and errors Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 1795f879 2010-11-05T03:20:17 Improve error handling All initialization functions now return error codes instead of pointers. Error codes are now properly propagated on most functions. Several new and more specific error codes have been added in common.h Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 58519018 2010-10-28T02:07:18 Fix internal memory management on the library String mememory is now managed in a much more sane manner. Fixes include: - git_person email and name is no longer limited to 64 characters - git_tree_entry filename is no longer limited to 255 characters - raw objects are properly opened & closed the minimum amount of times required for parsing - unit tests no longer leak - removed 5 other misc memory leaks as reported by Valgrind - tree writeback no longer segfaults on rare ocassions The git_person struct is no longer public. It is now managed by the library, and getter methods are in place to access its internal attributes. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti ec25391d 2010-10-07T00:20:08 Add write-back support for Tag files Tag files can now be created and modified in-memory (all the setter methods have been implemented), and written back to disk using the generic git_object_write() method. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti d45b4a9a 2010-09-20T21:39:11 Add support for in-memory objects All repository objects can now be created from scratch in memory using either the git_object_new() method, or the corresponding git_XXX_new() for each object. So far, only git_commits can be written back to disk once created in memory. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti f49a2e49 2010-09-19T03:21:06 Give object structures more descriptive names The 'git_obj' structure is now called 'git_rawobj', since it represents a raw object read from the ODB. The 'git_repository_object' structure is now called 'git_object', since it's the base object class for all objects. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti a7a7ddbe 2010-09-18T19:16:04 Add generic methods for object writeback git_repository_object has now several internal methods to write back the object information in the repository. - git_repository__dbo_prepare_write() Prepares the DBO object to be modified - git_repository__dbo_write() Writes new bytes to the DBO object - git_repository__dbo_writeback() Writes back the changes to the repository Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti f2408cc2 2010-08-12T19:59:32 Fix object handling in git_repository All loaded objects through git_repository_lookup are properly parsed & free'd on failure. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 3315782c 2010-08-08T14:12:17 Redesigned the walking/object lookup interface The old 'git_revpool' object has been removed and split into two distinct objects with separate functionality, in order to have separate methods for object management and object walking. * A new object 'git_repository' does the high-level management of a repository's objects (commits, trees, tags, etc) on top of a 'git_odb'. Eventually, it will also manage other repository attributes (e.g. tag resolution, references, etc). See: src/git/repository.h * A new external method 'git_repository_lookup(repo, oid, type)' has been added to the 'git_repository' API. All object lookups (git_XXX_lookup()) are now wrappers to this method, and duplicated code has been removed. The method does automatic type checking and returns a generic 'git_revpool_object' that can be cast to any specific object. See: src/git/repository.h * The external methods for object parsing of repository objects (git_XXX_parse()) have been removed. Loading objects from the repository is now managed through the 'lookup' functions. These objects are loaded with minimal information, and the relevant parsing is done automatically when the user requests any of the parsed attributes through accessor methods. An attribute has been added to 'git_repository' in order to force the parsing of all the repository objects immediately after lookup. See: src/git/commit.h See: src/git/tag.h See: src/git/tree.h * The previous walking functionality of the revpool is now found in 'git_revwalk', which does the actual revision walking on a repository; the attributes when walking through commits in a database have been decoupled from the actual commit objects. This increases performance when accessing commits during the walk and allows to have several 'git_revwalk' instances working at the same time on top of the same repository, without having to load commits in memory several times. See: src/git/revwalk.h * The old 'git_revpool_table' has been renamed to 'git_hashtable' and now works as a generic hashtable with support for any kind of object and custom hash functions. See: src/hashtable.h * All the relevant unit tests have been updated, renamed and grouped accordingly. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti f8758044 2010-08-07T01:02:20 Add loading and parsing of tag objects Tag objects are now properly loaded from the revision pool. New test t0801 checks for loading a parsing a series of tags, including the tag of a tag. Signed-off-by: Vicent Marti <tanoku@gmail.com>
