* Redesigned the walking/object lookup interfaceVicent Marti2010-08-121-52/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Changed revpool's object table to support arbitrary objectsVicent Marti2010-07-151-0/+3
| | | | | | | | | | | | git_revpool_object now has a type identifier for each object type in a revpool (commits, trees, blobs, etc). Trees can now be stored in the revision pool. git_revpool_tableit now supports filtering objects by their type when iterating through the object table. Signed-off-by: Vicent Marti <tanoku@gmail.com>

* Add topological sorting and new insertion methods for commit lists.Vicent Marti2010-06-021-0/+9
| | | | | | | | | | | | 'git_commit_list_toposort()' and 'git_commit_list_timesort()' now sort a commit list by topological and time order respectively. Both sorts are stable and in place. 'git_commit_list_append' has been replaced by 'git_commit_list_push_back' and 'git_commit_list_push_front'. Signed-off-by: Vicent Marti <tanoku@gmail.com> Signed-off-by: Andreas Ericsson <ae@op5.se>
* Add object cache to the revision pool.Vicent Marti2010-06-021-1/+2
| | | | | | | | | | | Fixed issue when generating pending commits list during iteration. The 'git_commit_lookup' function will now check the pool's cache for commits which have been previously loaded/parsed; there can only be a single 'git_commit' structure for each commit on the same pool.

* Add 'git_revpool_object' and 'git_revpool_table' structures.Vicent Marti2010-06-021-0/+39
All the objects which will will be eventually transversable from a revision pool (commits, trees, etc) now inherit from the 'git_revpool_object' structure which identifies them with their own OID. Furthermore, the 'git_revpool_table' and related functions have been added, which allow for constant time lookup (hash table) of the loaded revpool objects based on their OID.
