* Added Object interface for Commit, Tree, Blob and TagJoshua Sjoding2016-03-081-90/+75
| | | | | | | | | | | | | * New Object interface is distinct from core.Object * New Object interface is used in places where returned object could be of any type * Object is implemented by Commit, Tree, Blob, File and Tag * Added Repository.Object function for retrieving objects of any type * Tag.Object now returns Object instead of core.Object * Tag target hash is now publicly accessible * Renamed Tag.Type field to Tag.TargetType, making it distinct from Tag.Type function * Fixed infinite recursive loop in TagIter.Close * TreeWalker.Next now returns Object instead of core.Object * Removed some duplicate test setup code
* New iteration behavior via FileIter and TreeWalkerJoshua Sjoding2016-02-171-0/+134
Instead of returning a channel of files, Tree.Files() now returns a FileIter with these qualities: * It returns files in the original order of the repository (relying on a * new Tree.OrderedNames property) * It can return errors encountered when retrieving files and trees from * underlying storage * It can be Closed without having to drain the entire channel * It defers the heavy lifting to a new TreeWalker type * Its behavior is a little more consistent with other Iter types * It's a little less prone to memory leaks This update includes a new TreeWalker type that will iterate through all of the entries of a tree and its descendant subtrees. It does the dirty work that Tree.walkEntries() used to do, but with a public API. A new TreeIter type is also included that just walks through subtrees. This could be useful for performing a directory search while ignoring files/blobs altogether.
