Add back the LRU cache to `Throttled`. (#1731) * Restore `RequestResponse::throttled`. In contrast to the existing "throttled" approach this PR adds back- pressure to the protocol without requiring pre-existing knowledge of all nodes about their limits. It adds small, CBOR-encoded headers to the actual payload data. Extra credit messages communicate back to the sender how many more requests it is allowed to send. * Remove some noise. * Resend credit grant after connection closed. Should an error in some lower layer cause a connection to be closed, our previously sent credit grant may not have reached the remote peer. Therefore, pessimistically, a credit grant is resent whenever a connection is closed. The remote ignores duplicate grants. * Remove inbound/outbound tracking per peer. * Send ACK as response to duplicate credit grants. * Simplify. * Fix grammar. * Incorporate review feedback. - Remove `ResponseSent` which was a leftover from previous attemps and issue a credit grant immediately in `send_response`. - Only resend credit grants after a connection is closed if we are still connected to this peer. * Move codec/header.rs to throttled/codec.rs. * More review suggestions. * Generalise `ProtocolWrapper` and use shorter prefix. * Update protocols/request-response/src/lib.rs Co-authored-by: Roman Borschel <romanb@users.noreply.github.com> * Update protocols/request-response/src/throttled.rs Co-authored-by: Roman Borschel <romanb@users.noreply.github.com> * Update protocols/request-response/src/throttled.rs Co-authored-by: Roman Borschel <romanb@users.noreply.github.com> * Minor comment changes. * Limit max. header size to 8KiB * Always construct initial limit with 1. Since honest senders always assume a send budget of 1 and wait for credit afterwards, setting the default limit to a higher value can only become effective after informing the peer about it which means leaving `max_recv` at 1 and setting `next_max` to the desired value. * Use LRU cache to keep previous peer infos. Peers may send all their requests, reconnect and send again all their requests, starting from a fresh budget. The LRU cache keeps the peer information around and reuses it when the peer reconnects, continuing with the previous remaining limit. Co-authored-by: Roman Borschel <romanb@users.noreply.github.com>

request-response protocol via `RequestResponse::throttled()`.
2020-09-07 17:25:15 +02:00
[PR 1726](https://github.com/libp2p/rust-libp2p/pull/1726).
- Update `libp2p-swarm` and `libp2p-core`.
# 0.2.0 [2020-08-18]
[core/swarm] Emit events for active connection close and fix `disconnect()`. (#1619) * Emit events for active connection close and fix `disconnect()`. The `Network` does currently not emit events for actively closed connections, e.g. via `EstablishedConnection::close` or `ConnectedPeer::disconnect()`. As a result, when actively closing connections, there will be `ConnectionEstablished` events emitted without eventually a matching `ConnectionClosed` event. This seems undesirable and has the consequence that the `Swarm::ban_peer_id` feature in `libp2p-swarm` does not result in appropriate calls to `NetworkBehaviour::inject_connection_closed` and `NetworkBehaviour::inject_disconnected`. Furthermore, the `disconnect()` functionality in `libp2p-core` is currently broken as it leaves the `Pool` in an inconsistent state. This commit does the following: 1. When connection background tasks are dropped (i.e. removed from the `Manager`), they always terminate immediately, without attempting an orderly close of the connection. 2. An orderly close is sent to the background task of a connection as a regular command. The background task emits a `Closed` event before terminating. 3. `Pool::disconnect()` removes all connection tasks for the affected peer from the `Manager`, i.e. without an orderly close, thereby also fixing the discovered state inconsistency due to not removing the corresponding entries in the `Pool` itself after removing them from the `Manager`. 4. A new test is added to `libp2p-swarm` that exercises the ban/unban functionality and places assertions on the number and order of calls to the `NetworkBehaviour`. In that context some new testing utilities have been added to `libp2p-swarm`. This addresses https://github.com/libp2p/rust-libp2p/issues/1584. * Update swarm/src/lib.rs Co-authored-by: Toralf Wittner <tw@dtex.org> * Incorporate some review feedback. * Adapt to changes in master. * More verbose panic messages. * Simplify There is no need for a `StartClose` future. * Fix doc links. * Further small cleanup. * Update CHANGELOGs and versions.

- Fixed connection keep-alive, permitting connections to close due
to inactivity.

- Bump `libp2p-core` and `libp2p-swarm` dependencies.
# 0.1.1
- Always properly `close()` the substream after sending requests and
responses in the `InboundUpgrade` and `OutboundUpgrade`. Otherwise this is
left to `RequestResponseCodec::write_request` and `RequestResponseCodec::write_response`,
which can be a pitfall and lead to subtle problems (see e.g.
https://github.com/libp2p/rust-libp2p/pull/1606).
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>
