  1. Be careful when dereferencing tags.

    Junio C Hamano committed
    One caller of deref_tag() was not careful enough to make sure
    what deref_tag() returned was not NULL (i.e. we found a tag
    object that points at an object we do not have).  Fix it, and
    warn about refs that point at such an incomplete tag where

  1. Fix send-pack for non-commitish tags.

    Junio C Hamano committed
    Again I left the v2.6.11-tree tag behind.  My bad.
    This commit makes sure that we do not barf when pushing a ref
    that is a non-commitish tag.  You can update a remote ref under
    the following conditions:
     * You can always use --force.
     * Creating a brand new ref is OK.
     * If the remote ref is exactly the same as what you are
       pushing, it is OK (nothing is pushed).
     * You can replace a commitish with another commitish which is a
       descendant of it, if you can verify the ancestry between them;
       this and the above means you have to have what you are replacing.
     * Otherwise you cannot update; you need to use --force.

  1. [PATCH] don't load and decompress objects twice with parse_object()

    Nicolas Pitre committed with Linus Torvalds
    It turns out that parse_object() is loading and decompressing given
    object to free it just before calling the specific object parsing
    function which does mmap and decompress the same object again. This
    patch introduces the ability to parse specific objects directly from a
    memory buffer.
    Without this patch, running git-fsck-cache on the kernel repositorytake:
    	real    0m13.006s
    	user    0m11.421s
    	sys     0m1.218s
    With this patch applied:
    	real    0m8.060s
    	user    0m7.071s
    	sys     0m0.710s
    The performance increase is significant, and this is kind of a
    prerequisite for sane delta object support with fsck.

  1. Fix up recent object model cleanups

    Linus Torvalds committed
    Make sure the Makefile knows about the object header dependencies, and
    add declarations for tag lookup/parsing.
  2. [PATCH] Add tag header/parser to library

    Daniel Barkalow committed with Linus Torvalds
    This adds preliminary support for tags in the library. It doesn't even
    store the signature, however, let alone provide any way of checking it.
