From 11e7d5c594e79258f73c8c2a2e7e90dd60d05ce3 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sun, 1 May 2005 19:28:18 -0700 Subject: [PATCH] Make "cat-file" use "read_object_with_reference()" This means that you can take a tag object, and do git-cat-file commit tagname and it will cat the commit that the tag points to. Or you can cat the tree that a commit (or tag) points to. It still gives the old behaviour if you just give it the original type, ie if you want to see the tag object itself, you'd do git-cat-file -t tagname and you'd get the expected tag output. --- cat-file.c | 21 ++++++++++++--------- 1 file changed, 12 insertions(+), 9 deletions(-) diff --git a/cat-file.c b/cat-file.c index d253ff938..6bbb0ca01 100644 --- a/cat-file.c +++ b/cat-file.c @@ -14,18 +14,21 @@ int main(int argc, char **argv) if (argc != 3 || get_sha1(argv[2], sha1)) usage("cat-file [-t | tagname] "); - buf = read_sha1_file(sha1, type, &size); - if (!buf) - die("cat-file %s: bad file", argv[2]); + if (!strcmp("-t", argv[1])) { - buf = type; - size = strlen(type); - type[size] = '\n'; - size++; - } else if (strcmp(type, argv[1])) { - die("cat-file %s: bad tag", argv[2]); + buf = read_sha1_file(sha1, type, &size); + if (buf) { + buf = type; + size = strlen(type); + type[size] = '\n'; + } + } else { + buf = read_object_with_reference(sha1, argv[1], &size, NULL); } + if (!buf) + die("cat-file %s: bad file", argv[2]); + while (size > 0) { long ret = write(1, buf, size); if (ret < 0) { -- 2.26.2
