      offchain: Upgrade hyper to 0.13, which uses tokio 0.2 (#4860) · 0c8e0592
      Igor Matuszewski authored
      * service: Don't depend on tokio-executor
      
      Seems to be a leftover dependency that's not used anymore.
      
      * offchain: Upgrade hyper to 0.13, which uses tokio 0.2
      
      * offchain: Adapt HTTP tests to Tokio 0.2
      
      * network: Don't transitively include tokio 0.2 in WASM
      
      1) We don't specifically depend on Tokio codec impls
      2) Conflating features in Cargo means that enabling Tokio runtime
      in the native environment will also do so in WASM, where it's
      obviously not implemented and causes a compilation error.
      
      * grafana-data-source: Pull hyper/tokio only in native environment

      * contracts: Allow to distinguish out of gas from other traps
      
      When a contract encounters a runtime error a wasm trap is
      triggered and the execution is halted. Currently, no matter
      what was the cause for the trap it is always reported as:
      DispatchError::Other("contract trapped during execution").
      
      However, the trap that is triggered if a contract exhausts
      its gas budget is particulary interesting. Therefore we add
      a seperate error message for this cause:
      DispatchError::Other("ran out of gas during contract execution").
      
      A test is added hat executes a contract that never terminates.
      Therefore it always exhausts is gas budget.

      client/network-gossip: Integrate GossipEngine tasks into Future impl (#4767) · e1668c2a
      Max Inden authored
      `GossipEngine` spawns two tasks, one for a periodic tick, one to forward
      messages from the network to subscribers. These tasks hold an `Arc` to a
      `GossipEngineInner`.
      
      To reduce the amount of shared ownership (locking) this patch integrates
      the two tasks into a `Future` implementation on the `GossipEngine`
      struct. This `Future` implementation can now be called from a single
      owner, e.g. the `finality-grandpa` `NetworkBridge`.
      
      As a side effect this removes the requirement on the `network-gossip`
      crate to spawn tasks and thereby removes the requirement on the
      `finality-grandpa` crate to spawn any tasks.
      
      This is part of a greater effort to reduce the number of owners of
      components within `finality-grandpa`, `network` and `network-gossip` as
      well as to reduce the amount of unbounded channels. For details see
      d4fbb897, f0c18520 and 5afc7777.

      network: Use "one shot" protocol handler. (#3520) · ea721a19
      Toralf Wittner authored
      * network: Use "one shot" protocol handler.
      
      Add two new `NetworkBehaviour`s, one handling remote block requests
      and another one to handle light client requests (both local and from
      remote). The change is motivated by the desire to use multiple
      substreams of a single connection for different protocols. To achieve
      this, libp2p's `OneShotHandler` is used as a protocol handler in each
      behaviour. It will open a fresh substream for the duration of the
      request and close it afterwards. For block requests, we currently only
      handle incoming requests from remote and tests are missing. For light
      client handling we support incoming requests from remote and also
      ported a substantial amount of functionality over from
      `light_dispatch.rs` (including several tests). However the result lacks
      in at least two aspects:
      
      (1) We require external updates w.r.t. the best block per peer and
      currently nothing updates this information.
      (2) We carry a lot of peer-related state around.
      
      Both aspects could be simplified by externalising peer selection and
      just requiring a specific peer ID where the request should be sent to.
      We still have to maintain some peer related state due to the way
      libp2p's swarm and network behaviour work (e.g. we must make sure to
      always issue `NetworkBehaviourAction::SendEvent`s to peers we are
      connected to, otherwise the actions die a silent death.
      
      Another change implemented here is the use of protocol buffers as the
      encoding for network messages. Certain individual fields of messages
      are still SCALE encoded. There has been some discussion about this
      in another PR (https://github.com/paritytech/substrate/pull/3452), so
      far without resolution.
      
      * Uncomment `Behaviour::light_client_request`.
      
      * Add license headers.

      Add command-line flag to enable yamux flow control. (#4892) · f5f7852a
      Toralf Wittner authored
      * Add command-line flag to enable yamux flow control.
      
      We never enabled proper flow-control for yamux streams which may cause
      stream buffers to exceed their configured limit when the stream
      producer outpaces the stream consumer. By switching the window update
      mode to on-read, producers will only receive more sending credit when
      all data has been consumed from the stream buffer. Using this option
      creates backpressure on producers. However depending on the protocol
      there is a risk of deadlock, if both endpoints concurrently attempt to
      send more data than they have credit for and neither side reads before
      finishing their writes. To facilitate proper testing, this PR adds a
      command-line flag `use-yamux-flow-control`.
      
      * Replace comment with generic message.
