Marc Pegon da03c9f3 2011-05-29T11:45:34 Changed return value of git_oid_match to be consistent with the other compare methods (0 means oids match). Added method to compare prefixes of hex formatted oids.
Marc Pegon 53c0bd81 2011-05-27T22:37:10 Added error for ambiguous oid prefixes. Added methods to compare the first nth hexadecimal characters (i.e. packets of 4 bits) of OIDs.

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 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 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>
nulltoken 6f02c3ba 2010-12-05T20:18:56 Small source code readability improvements. Replaced magic number "0" with GIT_SUCCESS constant wherever it made sense.
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>
Ramsay Jones 552e23ba 2010-06-02T19:16:28 Fix a bug in the git_oid_to_string() function When git_oid_to_string() was passed a buffer size larger than GIT_OID_HEXSZ+1, the function placed the c-string NUL char at the wrong position. Fix the code to place the NUL at the end of the (possibly truncated) oid string. Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk>

Shawn O. Pearce 64a47c01 2008-12-30T23:21:36 Wrap malloc and friends and report out of memory as GIT_ENOMEM We now forbid direct use of malloc, strdup or calloc within the library and instead use wrapper functions git__malloc, etc. to invoke the underlying library malloc and set git_errno to a no memory error code if the allocation fails. In the future once we have pack objects in memory we are likely to enhance these routines with garbage collection logic to purge cached pack data when allocations fail. Because the size of the function will grow somewhat large, we don't want to mark them for inline as gcc tends to aggressively inline, creating larger than expected executables.

Ramsay Jones b3be0fc7 2008-12-03T23:54:47 Fix an "implicit function definition" warning on cygwin In particular, the warning relates to malloc(), which is declared in <stdlib.h>.

Shawn O. Pearce af795e49 2008-12-02T09:56:23 Add routines to convert git_oid to hex strings [sp: Credit for some of this implementation goes to Pieter, I started off a patch he proposed for libgit2 but reworked enough of it that I don't want to blame him for any bugs.] Suggested-by: Pieter de Bie <pdebie@ai.rug.nl> Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
Shawn O. Pearce b7c891c6 2008-11-03T17:31:16 Add git_oid_cpy, git_oid_cmp as inline functions These are easily built off the standard C library functions memcpy and memcmp. By marking these inline we stand a good chance of the C compiler replacing the entire thing with tight machine code, because many compilers will actually inline a memcmp or memcpy when the 3rd argument (the size) is a constant value.
