    • 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
      --------
      
      	- Remove `git_commit_new`

    • 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.

    • Fix internal memory management on the library · 58519018
      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.

    • Add setter methods & write support for git_commit · 0c3596f1
      All the required git_commit_set_XXX methods have been implemented; all
      the attributes of a commit object can now be modified in-memory.
      
      The new method git_object_write() automatically writes back the
      in-memory changes of any object to the repository. So far it only
      supports git_commit objects.

    • Give object structures more descriptive names · f49a2e49
      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.

    • Redesigned the walking/object lookup interface · 3315782c
      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.

    • Add external API to access detailed commit attributes · 52f2390b
      The following new external methods have been added:
      
      GIT_EXTERN(const char *) git_commit_message_short(git_commit *commit);
      GIT_EXTERN(const char *) git_commit_message(git_commit *commit);
      GIT_EXTERN(time_t) git_commit_time(git_commit *commit);
      GIT_EXTERN(const git_commit_person *) git_commit_committer(git_commit *commit);
      GIT_EXTERN(const git_commit_person *) git_commit_author(git_commit *commit);
      GIT_EXTERN(const git_tree *) git_commit_tree(git_commit *commit);
      
      A new structure, git_commit_person has been added to represent a
      commit's author or committer.
      
      The parsing of a commit has been split in two phases.
      When adding a commit to the revision pool:
      	- the commit's ODB object is opened
      	- its raw contents are parsed for commit TIME, PARENTS and TREE
      		(the minimal amount of data required to traverse the pool)
      	- the commit's ODB object is closed
      
      When querying for extended information on a commit:
      	- the commit's ODB object is reopened
      	- its raw contents are parsed for the requested information
      	- the commit's ODB object remains open to handle additional queries
      
      New unit tests have been added for the new functionality:
      
      	In t0401-parse: parse_person_test
      	In t0402-details: query_details_test

      type when iterating through the object table.

      Using it in the first place means something's wrong.
      This patch replaces it with an internal header which
      carries the previously "protected" code instead.
      
      Internal source-files simply include "commit.h" and
      they're done. The internal header includes the public
      one to make sure we always use the proper prototype.
