    • Reorg internal odb read header and object lookup · c6ac28fd
      Often `git_odb_read_header` will "fail" and have to read the
      entire object into memory instead of just the header.  When this
      happens, the object is loaded and then disposed of immediately,
      which makes it difficult to efficiently use the header information
      to decide if the object should be loaded (since attempting to do
      so will often result in loading the object twice).
      
      This commit takes the existing code and reorganizes it to have
      two new functions:
      
      - `git_odb__read_header_or_object` which acts just like the old
        read header function except that it returns the object, too, if
        it was forced to load the whole thing.  It then becomes the
        callers responsibility to free the `git_odb_object`.
      - `git_object__from_odb_object` which was extracted from the old
        `git_object_lookup` and creates a subclass of `git_object` from
        an existing `git_odb_object` (separating the ODB lookup from the
        `git_object` creation).  This allows you to use the first header
        reading function efficiently without instantiating the
        `git_odb_object` twice.
      
      There is no net change to the behavior of any of the existing
      functions, but this allows internal code to tap into the ODB
      lookup and object creation to be more efficient.

    • Make git_object_peel a bit smarter · d8057a5b
      This expands the types of peeling that `git_object_peel` knows
      how to do to include TAG -> BLOB peeling, and makes the errors
      slightly more consistent depending on the situation.  It also
      adds a new special behavior where peeling to ANY will peel until
      the object type changes (e.g. chases TAGs to a non-TAG).
      
      Using this expanded peeling, this replaces peeling code that was
      embedded in `git_tag_peel` and `git_reset`.

    • Fix valgrind issues · 282283ac
      There are three changes here:
      - correctly propogate error code from failed object lookups
      - make zlib inflate use our allocators
      - add OID to notfound error in ODB lookups

    • Support reading attributes from index · f917481e
      Depending on the operation, we need to consider gitattributes
      in both the work dir and the index.  This adds a parameter to
      all of the gitattributes related functions that allows user
      control of attribute reading behavior (i.e. prefer workdir,
      prefer index, only use index).
      
      This fix also covers allowing us to check attributes (and
      hence do diff and status) on bare repositories.
      
      This was a somewhat larger change that I hoped because it had
      to change the cache key used for gitattributes files.

    • Migrate ODB files to new error handling · e1de726c
      This migrates odb.c, odb_loose.c, odb_pack.c and pack.c to
      the new style of error handling.  Also got the unix and win32
      versions of map.c.  There are some minor changes to other
      files but no others were completely converted.
      
      This also contains an update to filebuf so that a zeroed out
      filebuf will not think that the fd (== 0) is actually open
      (and inadvertently call close() on fd 0 if cleaned up).
      
      Lastly, this was built and tested on win32 and contains a
      bunch of fixes for the win32 build which was pretty broken.

    • Rename all `_close` methods · 45e79e37
      There's no difference between `_free` and `_close` semantics: keep
      everything with the same name to avoid confusions.

    • repository: Change ownership semantics · 9462c471
      The ownership semantics have been changed all over the library to be
      consistent. There are no more "borrowed" or duplicated references.
      
      Main changes:
      
      	- `git_repository_open2` and `3` have been dropped.
      
      	- Added setters and getters to hotswap all the repository owned
      	objects:
      
      		`git_repository_index`
      		`git_repository_set_index`
      		`git_repository_odb`
      		`git_repository_set_odb`
      		`git_repository_config`
      		`git_repository_set_config`
      		`git_repository_workdir`
      		`git_repository_set_workdir`
      
      	Now working directories/index files/ODBs and so on can be
      	hot-swapped after creating a repository and between operations.
      
      	- All these objects now have proper ownership semantics with
      	refcounting: they all require freeing after they are no longer
      	needed (the repository always keeps its internal reference).
      
      	- Repository open and initialization has been updated to keep in
      	mind the configuration files. Bare repositories are now always
      	detected, and a default config file is created on init.
      
      	- All the tests affected by these changes have been dropped from the
      	old test suite and ported to the new one.

    • Tabify everything · 87d9869f
      There were quite a few places were spaces were being used instead of
      tabs. Try to catch them all. This should hopefully not break anything.

    • Cleanup legal data · bb742ede
      1. The license header is technically not valid if it doesn't have a
      copyright signature.
      
      2. The COPYING file has been updated with the different licenses used in
      the project.
      
      3. The full GPLv2 header in each file annoys me.

    • I broke your bindings · 72a3fe42
      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
      --------

      	- 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)

    • Fix the retarded object interdependency system · 6b2a1941
      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.
