[PATCH] Add tag header/parser to library 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.

[PATCH] Anal retentive 'const unsigned char *sha1' Make 'sha1' parameters const where possible Signed-off-by: Jason McMullan <jason.mcmullan@timesys.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org> 2005-06-03 23:05:39 +08:00			`extern struct tag lookup_tag(const unsigned char sha1);`
[PATCH] don't load and decompress objects twice with parse_object() 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.

Fix up recent object model cleanups Make sure the Makefile knows about the object header dependencies, and add declarations for tag lookup/parsing. 2005-04-28 22:50:39 +08:00			`extern int parse_tag(struct tag *item);`
Be careful when dereferencing tags. 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 needed.
