use get_commit_buffer to avoid duplicate code
For both of these sites, we already do the "fallback to read_sha1_file" trick. But we can shorten the code by just using get_commit_buffer. Note that the error cases are slightly different when read_sha1_file fails. get_commit_buffer will die() if the object cannot be loaded, or is a non-commit. For get_sha1_oneline, this will almost certainly never happen, as we will have just called parse_object (and if it does, it's probably worth complaining about). For record_author_date, the new behavior is probably better; we notify the user of the error instead of silently ignoring it. And because it's used only for sorting by author-date, somebody examining a corrupt repo can fallback to the regular traversal order. Signed-off-by: Jeff King <> Signed-off-by: Junio C Hamano <>
