* Update go-libp2p to 0.12.0 go-libp2p 0.12.0 made some significant changes to the stream interfaces around stream closing: * Close now closes in both directions and frees the stream. However, unlike FullClose did, it doesn't _wait_ for the remote peer to respond with an EOF. * To close for writing, call CloseWrite (like one would on a TCP connection, etc.). This patch: * Replaces calls to FullClose with Close where appropriate. * Replaces calls to Close with CloseWrite where appropriate. * Removes redundant Close calls. * Calls Reset to where appropriate to indicate that the request/response was aborted. Unlike Close, this will not flush and will not cause the remote peer to read an EOF. Instead, the remote peer will read an ErrReset error. * Ensures we always either close or reset streams. Send wasn't closing the stream on some error paths. * Now that stream closing is async, we explicitly wait for a response when "hanging up" on a peer (so we don't hang up before they receive our response/goodbye message). * update bazel * Gazelle * revert unintentional bazel workspace change * appease an overzealous linter * update to latest * Refactor encoder * gazelle * Gazelle Co-authored-by: Preston Van Loon <preston@prysmaticlabs.com> Co-authored-by: Nishant Das <nishdas93@gmail.com> Co-authored-by: Raul Jordan <raul@prysmaticlabs.com>
