I get nil for blob.name when fetched directly from the Repo

[krisleech]

r=Repo.new('~/git/test')
c=r.commits('114456d6606ca35c8ceec669aebb3a5b56ebdd0d').first
b=c.tree.contents.first
b.name #=> "README"
bb = r.blob(b.id)
bb.name #=> nil

Grit version 2.0

who give me a answer?I run into the same issue.

When looking up a blob, eg. r.blob(b.id), you get an 'unbaked' blob. This is the terminology used in the source code and it seems to suggest the blob instance has not been populated with any values yet. I do not know how to 'bake' the blob however.

"A "blob" object is nothing but a chunk of binary data. It doesn't refer to anything else or have attributes of any kind, not even a file name.

Since the blob is entirely defined by its data, if two files in a directory tree (or in multiple different versions of the repository) have the same contents, they will share the same blob object. The object is totally independent of its location in the directory tree, and renaming a file does not change the object that file is associated with." -- from http://book.git-scm.com/1_the_git_object_model.html

A blob only gets a name if it is initialized via an action where it would have a name (e.g. tree traversal). Looking up a blob by its id will only return the content, size, and type.
