This extends the vector library with an insert function. It is more expensive than appending, but this does not affect existing code using vector and can be used in new places without making those uses more expensive. We use this function in nbdkit-extentlist-filter, nbdkit-eval-plugin and the sparse library. This is refactoring, so should not affect functionality at all. However during the

The NBD protocol is adding an extension to let servers advertise initialization state to the client: whether the image contains holes, and whether it is known to read as all zeroes. For memory-based plugins, it is fairly easy to advertise several cases: data and memory are usually sparse and detecting zero is easy (requires new functions to the sparse_array common code), although since the sparse

I will be following up to this email with four separate threads each addressed to the appropriate single list, with proposed changes to: - the NBD protocol - qemu: both server and client - libnbd: client - nbdkit: server The feature in question adds a new optional NBD_INFO_ packet to the NBD_OPT_GO portion of handshake, adding up to 16 bits of information that the server can advertise to the
