Vicent Marti d0323a5f 2011-06-01T21:25:56 short-oid: Cleanup
Marc Pegon 6c8ca697 2011-05-29T17:57:25 Fixed some error messages related to searching objects from a short oid. Fixed forgot to check that prefix length is greater than minimum prefix length in read_unique_short_oid method from pack backend.
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.
Marc Pegon ecd6fdf1 2011-05-27T18:49:09 Added a read_unique_short_oid method to backends, to make it possible to find objects from sha1 prefixes in the future. Default implementations throw GIT_ENOTIMPLEMENTED for strict prefixes (i.e. length < GIT_OID_HEXSZ).

Vicent Martí 273c8bc0 2011-05-01T14:59:11 Merge pull request #147 from nordsturm/fix_pack_backend_leak. Fix memory leak in pack_backend__free
Vicent Marti c7b79af3 2011-05-01T21:31:58 pack-odb: Check `mtime` instead of folder size Do not check the folder's size to detect new packfiles at runtime. This doesn't work on Win32.

Vicent Marti 90d743cd 2011-04-15T15:12:37 Refresh the list of packfiles on each ODB query Fixes the issue where object lookups were failing right after a pull on an open repository.
nulltoken 56d8ca26 2011-03-20T18:36:25 Switch from time_t to git_time_t git_time_t is defined as a signed 64 integer. This allows a true predictable multiplatform behavior.
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 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 d4b5a4e2 2011-02-09T19:49:02 Internal changes on the backend system The priority value for different backends has been removed from the public `git_odb_backend` struct. We handle that internally. The priority value is specified on the `git_odb_add_alternate`. This is convenient because it allows us to poll a backend twice with different priorities without having to instantiate it twice. We also differentiate between main backends and alternates; alternates have lower priority and cannot be written to. These changes come with some unit tests to make sure that the backend sorting is consistent. The libgit2 version has been bumped to 0.4.0. This commit changes the external API: CHANGED: struct git_odb_backend No longer has a `priority` attribute; priority for the backend in managed internally by the library. git_odb_add_backend(git_odb *odb, git_odb_backend *backend, int priority) Now takes an additional priority parameter, the priority that will be given to the backend. ADDED: git_odb_add_alternate(git_odb *odb, git_odb_backend *backend, int priority) Add a backend as an alternate. Alternate backends have always lower priority than main backends, and writing is disabled on them. Signed-off-by: Vicent Marti <tanoku@gmail.com> Signed-off-by: Vicent Marti <tanoku@gmail.com>
Alex Budovski f0bde7fa 2011-01-11T16:07:45 Revised platform types to use 'best supported' size. This will allow graceful migration to 64 bit file sizes and timestamps should git's binary interface be extended to allow this.
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 7d7cd885 2010-12-03T18:01:30 Decouple storage from ODB logic Comes with two default backends: loose object and packfiles. Signed-off-by: Vicent Marti <tanoku@gmail.com>
