In the "next" branch, write_index_ext_header() writes garbage on a 64-bit big-endian machine; the written index file will be unreadable. I noticed this on NetBSD/sparc64. Reproducible with: $ git init-db $ :>file $ git-update-index --add file $ git-write-tree $ git-update-index error: index uses extension, which we do not understand fatal: index file corrupt Signed-off-by: Dennis Stosberg <dennis@xxxxxxxxxxxx> --- read-cache.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/read-cache.c b/read-cache.c index 36bd4ea..c499c51 100644 --- a/read-cache.c +++ b/read-cache.c @@ -826,7 +826,7 @@ static int ce_write(SHA_CTX *context, in } static int write_index_ext_header(SHA_CTX *context, int fd, - unsigned long ext, unsigned long sz) + unsigned int ext, unsigned int sz) { ext = htonl(ext); sz = htonl(sz); -- 1.3.3.g3c38f - : send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
