  Redesigned the walking/object lookup interface 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. Signed-off-by: Vicent Marti <tanoku@gmail.com>
