From e93ec6f9d8dd122557d54505129f7860b9301503 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 18 Jan 2006 20:26:14 -0800 Subject: Revert "check_packed_git_idx(): check integrity of the idx file itself." This reverts c5ced64578a82b9d172aceb2f67c6fb9e639f6d9 commit. It turns out that doing this check every time we map the idx file is quite expensive. A corrupt idx file is caught by git-fsck-objects, so this check is not strictly necessary. In one unscientific test, 0.99.9m spent 10 seconds usertime for the same task 1.1.3 takes 37 seconds usertime. Reverting this gives us the performance of 0.99.9 back. --- sha1_file.c | 16 +--------------- 1 file changed, 1 insertion(+), 15 deletions(-) diff --git a/sha1_file.c b/sha1_file.c index 6b7577dbc..d451a94ef 100644 --- a/sha1_file.c +++ b/sha1_file.c @@ -321,16 +321,12 @@ struct packed_git *packed_git; static int check_packed_git_idx(const char *path, unsigned long *idx_size_, void **idx_map_) { - SHA_CTX ctx; - unsigned char sha1[20]; void *idx_map; unsigned int *index; unsigned long idx_size; int nr, i; - int fd; + int fd = open(path, O_RDONLY); struct stat st; - - fd = open(path, O_RDONLY); if (fd < 0) return -1; if (fstat(fd, &st)) { @@ -368,16 +364,6 @@ static int check_packed_git_idx(const char *path, unsigned long *idx_size_, if (idx_size != 4*256 + nr * 24 + 20 + 20) return error("wrong index file size"); - /* - * File checksum. - */ - SHA1_Init(&ctx); - SHA1_Update(&ctx, idx_map, idx_size-20); - SHA1_Final(sha1, &ctx); - - if (memcmp(sha1, idx_map + idx_size - 20, 20)) - return error("index checksum mismatch"); - return 0; } -- cgit v1.2.1 From e921fb82cf6fb4a5f138ec9d27bc37c658336a8c Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Thu, 19 Jan 2006 00:24:04 +0100 Subject: git-fetch-pack: really do not ask for funny refs If git-fetch-pack was called with out any refspec, it would ask the server for funny refs. That cannot work, since the funny refs are not marked as OUR_REF by upload-pack, which just exits with an error.
