From abdb007d1f0ee1579c3719fc4fadbe4755163d74 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Tue, 19 Apr 2005 21:39:28 -0700 Subject: [PATCH] Make "diff-tree" take commit objects too, like "diff-cache" does. Sometimes it's just easier to not have to look up the "commit"->"tree" translation by hand first. It's trivial to do inside diff-tree, and it's just being polite. --- diff-tree.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/diff-tree.c b/diff-tree.c index 826812af8..65bb9d66c 100644 --- a/diff-tree.c +++ b/diff-tree.c @@ -179,6 +179,20 @@ static int diff_tree_sha1(const unsigned char *old, const unsigned char *new, co return retval; } +static void commit_to_tree(unsigned char *sha1) +{ + void *buf; + char type[20]; + unsigned long size; + + buf = read_sha1_file(sha1, type, &size); + if (buf) { + if (!strcmp(type, "commit")) + get_sha1_hex(buf+5, sha1); + free(buf); + } +} + int main(int argc, char **argv) { unsigned char old[20], new[20]; @@ -200,5 +214,7 @@ int main(int argc, char **argv) if (argc != 3 || get_sha1_hex(argv[1], old) || get_sha1_hex(argv[2], new)) usage("diff-tree "); + commit_to_tree(old); + commit_to_tree(new); return diff_tree_sha1(old, new, ""); } -- 2.26.2
