Add libp2p-request-response protocol. (#1596) * Add the libp2p-request-response protocol. This crate provides a generic implementation for request/response protocols, whereby each request is sent on a new substream. * Fix OneShotHandler usage in floodsub. * Custom ProtocolsHandler and multiple protocols. 1. Implement a custom ProtocolsHandler instead of using the OneShotHandler for better control and error handling. In particular, all request/response sending/receiving is kept in the substreams upgrades and thus the background task of a connection. 2. Support multiple protocols (usually protocol versions) with a single `RequestResponse` instance, with configurable inbound/outbound support. * Small doc clarification. * Remove unnecessary Sync bounds. * Remove redundant Clone constraint. * Update protocols/request-response/Cargo.toml Co-authored-by: Toralf Wittner <tw@dtex.org> * Update dev-dependencies. * Update Cargo.tomls. * Add changelog. * Remove Sync bound from RequestResponseCodec::Protocol. Apparently the compiler just needs some help with the scope of borrows, which is unfortunate. * Try async-trait. * Allow checking whether a ResponseChannel is still open. Also expand the commentary on `send_response` to indicate that responses may be discard if they come in too late. * Add `RequestResponse::is_pending`. As an analogue of `ResponseChannel::is_open` for outbound requests. * Revert now unnecessary changes to the OneShotHandler. Since `libp2p-request-response` is no longer using it. * Update CHANGELOG for libp2p-swarm. Co-authored-by: Toralf Wittner <tw@dtex.org>

.github/workflows: Refactor CI jobs (#3090) We refactor our continuous integration workflow with the following goals in mind: - Run as few jobs as possible - Have the jobs finish as fast as possible - Have the jobs redo as little work as possible There are only so many jobs that GitHub Actions will run in parallel. Thus, it makes sense to not create massive matrices but instead group things together meaningfully. The new `test` job will: - Run once for each crate - Ensure that the crate compiles on its specified MSRV - Ensure that the tests pass - Ensure that there are no semver violations This is an improvement to before because we are running all of these in parallel which speeds up execution and highlights more errors at once. Previously, tests run later in the pipeline would not get run at all until you make sure the "first" one passes. We also previously did not verify the MSRV of each crate, making the setting in the `Cargo.toml` rather pointless. The new `cross` job supersedes the existing `wasm` job. This is an improvement because we now also compile the crate for windows and MacOS. Something that wasn't checked before. We assume that checking MSRV and the tests under Linux is good enough. Hence, this job only checks for compile-errors. The new `feature_matrix` ensures we compile correctly with certain feature combinations. `libp2p` exposes a fair few feature-flags. Some of the combinations are worth checking independently. For the moment, this concerns only the executor related transports together with the executor flags but this list can easily be extended. The new `clippy` job runs for `stable` and `beta` rust. Clippy gets continuously extended with new lints. Up until now, we would only learn about those as soon as a new version of Rust is released and CI would run the new lints. This leads to unrelated failures in CI. Running clippy on with `beta` Rust gives us a heads-up of 6 weeks before these lints land on stable. Fixes #2951.

Add `Throttled` to libp2p-request-response. (#1696) * Use a single exchange instead of two one_shots. * Add `Throttled` to libp2p-request-response. Wraps the existing `RequestResponse` behaviour and applies strict limits to the number of inbound and outbound requests per peer. The wrapper is opt-in and if not used, the protocol behaviour of `RequestResponse` does not change. This PR also does not introduce an extra protocol, hence the limits applied need to be known a priori for all nodes which is not always possible or desirable. As mentioned in #1687 I think that we should eventually augment the protocol with metadata which allows a more dynamic exchange of requests and responses. This PR also replaces the two oneshot channels with a single one from the scambio crate which saves one allocation per request/response. If not desirable because the crate has seen less testing the first commit could be reverted. * Fix rustdoc error. * Remove some leftovers from development. * Add docs to `NetworBehaviourAction::{map_in,map_out}`. * Apply suggestions from code review Co-authored-by: Roman Borschel <romanb@users.noreply.github.com> * Add `ping_protocol_throttled` test. * Add another test. * Revert "Use a single exchange instead of two one_shots."
