Vicent Marti d79f1da6 2011-04-08T12:14:33 refs: Fix issue when packing weak tags Weak tags (e.g. tags that point directly to a normal object instead of a tag object) were failing to be packed.
Carlos Martín Nieto 83c95128 2011-03-24T14:15:00 normalize_name: allow more references under refs/ Allow any well-formed reference name to live under refs/ removing the condition that they be under refs/{heads,tags,remotes}/ as was the design of git. An exception is made for HEAD which is allowed to contain an OID reference in detached HEAD state. Signed-off-by: Carlos Martín Nieto <cmn@elego.de>
Vicent Marti 9a53df7e 2011-03-29T19:40:02 refs: Don't allow references to inexistent OIDs
Vicent Marti 95cde17c 2011-03-29T19:22:21 Enforce coding conventions in refs.c Internal methods are static and without the git prefix. 'Force' methods have a `_f` prefix to match the other 'force' methods.
Carlos Martín Nieto dad4a4d5 2011-03-29T10:47:48 rename: don't return early if the target ref exists Signed-off-by: Carlos Martín Nieto <cmn@elego.de>
Carlos Martín Nieto fa204962 2011-03-28T12:00:50 Allow forcing the creation or renaming of references Add internal reference create and rename functions which take a force parameter, telling them to overwrite an existing reference if it exists. These functions try to update the reference if it's of the same type as the one it's going to be replaced by. Otherwise the old reference becomes invalid.

Vicent Marti 09e8de0f 2011-03-25T23:53:38 New external API method: `git_reference_listcb` List all the references in the repository, calling a custom callback for each one. The listed references may be filtered by type, or using a bitwise OR of several types. Use the magic value `GIT_REF_LISTALL` to obtain all references, including packed ones. The `callback` function will be called for each of the references in the repository, and will receive the name of the reference and the `payload` value passed to this method.
Carlos Martín Nieto 567fc1d2 2011-03-22T12:47:53 refs loose_lookup: also free the buffer on success Free the ref_file buffer at the end of the function also on success. This fixes a small memory leak.
Vicent Marti 7341bf87 2011-03-16T23:13:28 Refs are now always in-sync on disk

Vicent Marti 7ad96e51 2011-03-15T05:38:50 Remove duplicate refs in `git_reference_listall`
Vicent Marti 7c8a7b91 2011-03-15T02:45:49 Skip the optional header in packed-refs files
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 55ffebe3 2011-03-05T14:34:32 Fix creation of deeply-rooted references Use a new `gitfo_creat_force` that will create the full path to a file before creating it. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti e06dd9b6 2011-03-04T15:23:52 Fix 'possibly uninitialized variable' warning
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 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.

nulltoken 8f90ced5 2011-03-03T19:55:48 Fix corner case in reference renaming Renaming a packed reference should not pack another reference which happens to be in both loose and pack state.

Vicent Marti 87d3acf4 2011-02-27T22:31:43 Finish the References API The following methods have been implemented: git_reference_packall git_reference_rename git_reference_delete The library now has full support for packed references, including partial and total writing. Internal documentation has been updated with the details. Signed-off-by: Vicent Marti <tanoku@gmail.com>
Vicent Marti 86194b24 2011-02-18T21:57:53 Split packed from unpacked references These two reference types are now stored separately to eventually allow the removal/renaming of loose references and rewriting of the refs packfile. Signed-off-by: Vicent Marti <tanoku@gmail.com>

nulltoken aa2120e9 2011-02-10T15:08:00 Added git_reference__normalize_name() along with tests.
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).

Vicent Marti 995f9c34 2011-02-09T12:43:19 Use the new git__joinpath to build paths in methods The `git__joinpath` function has been changed to use a statically allocated buffer; we assume the buffer to be 4096 bytes, because fuck you. The new method also supports an arbritrary number of paths to join, which may come in handy in the future. Some methods which were manually joining paths with `strcpy` now use the new function, namely those in `index.c` and `refs.c`. Based on Emeric Fermas' original patch, which was using the old `git__joinpath` because I'm stupid. Thanks! Signed-off-by: Vicent Marti <tanoku@gmail.com>

nulltoken 9282e921 2010-12-27T20:34:19 Merge nulltoken's reference parsing code All the commits have been squashed into a single one before refactoring the final code, to keep everything tidy. Individual commit messages are as follows: Added repository reference looking up functionality placeholder. Added basic reference database definition and caching infrastructure. Removed useless constant. Added GIT_EINVALIDREFNAME error and description. Added missing description for GIT_EBAREINDEX. Added GIT_EREFCORRUPTED error and description. Added GIT_ETOONESTEDSYMREF error and description. Added resolving of direct and symbolic references. Prepared the packed-refs parsing. Added parsing of the packed-refs file content. When no loose reference has been found, the full content of the packed-refs file is parsed. All of the new (i.e. not previously parsed as a loose reference) references are eagerly stored in the cached references storage. The method packed_reference_file__parse() is in deer need of some refactoring. :-) Extracted to a method the parsing of the peeled target of a tag. Extracted to a method the parsing of a standard packed ref. Fixed leaky removal of the cached references. Ensured that a previously parsed packed reference isn't returned if a more up-to-date loose reference exists. Enhanced documentation of git_repository_reference_lookup(). Moved some refs related constants from repository.c to refs.h. Made parsing of a packed tag reference more robust. Updated git_repository_reference_lookup() documentation. Added some references to the test repository. Added some tests covering tag references looking up. Added some tests covering symbolic and head references looking up. Added some tests covering packed references looking up.
