create_bundle(): duplicate file descriptor to avoid closing it twice
write_pack_data() passes bundle_fd to start_command() to be used as the stdout of pack-objects. But start_command() closes its stdout if it is > 1. This is a problem if bundle_fd is the fd of a lock_file, because commit_lock_file() will also try to close the fd. So the old code suppressed commit_lock_file()'s usual behavior of closing the file descriptor by setting the lock_file object's fd field to -1. But this is not really kosher. Code here shouldn't be mutating fields within the lock_file object. Instead, duplicate the file descriptor before passing it to write_pack_data(). Then that function can close its copy without closing the copy held in the lock_file object. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
