From ec4465adb38d21966acdc9510ff15c0fe4539468 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 25 Apr 2005 12:07:44 -0700 Subject: Add "tag" objects that can be used to sign other objects. You use "git-mktag" to create them, and fsck-cache knows how to parse them. --- fsck-cache.c | 39 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) (limited to 'fsck-cache.c') diff --git a/fsck-cache.c b/fsck-cache.c index e3c41d48e..12443b165 100644 --- a/fsck-cache.c +++ b/fsck-cache.c @@ -69,6 +69,42 @@ static int fsck_blob(unsigned char *sha1, void *data, unsigned long size) return 0; } +static int fsck_tag(unsigned char *sha1, void *data, unsigned long size) +{ + int typelen, taglen; + unsigned char object[20]; + const char *type_line, *tag_line, *sig_line; + + if (size < 64) + return -1; + if (memcmp("object ", data, 7) || get_sha1_hex(data + 7, object)) + return -1; + + type_line = data + 48; + if (memcmp("\ntype ", type_line-1, 6)) + return -1; + + tag_line = strchr(type_line, '\n'); + if (!tag_line || memcmp("tag ", ++tag_line, 4)) + return -1; + + sig_line = strchr(tag_line, '\n'); + if (!sig_line) + return -1; + sig_line++; + + typelen = tag_line - type_line - strlen("type \n"); + if (typelen >= 20) + return -1; + taglen = sig_line - tag_line - strlen("tag \n"); + + printf("tagged %.*s %s (%.*s)\n", + typelen, type_line + 5, + sha1_to_hex(object), + taglen, tag_line + 4); + return 0; +} + static int fsck_entry(unsigned char *sha1, char *tag, void *data, unsigned long size) { @@ -81,6 +117,9 @@ static int fsck_entry(unsigned char *sha1, char *tag, void *data, } else if (!strcmp(tag, "commit")) { if (fsck_commit(sha1, data, size) < 0) return -1; + } else if (!strcmp(tag, "tag")) { + if (fsck_tag(sha1, data, size) < 0) + return -1; } else return -1; return 0; -- cgit v1.2.1
