      Improve collator side of the collator-protocol (#1955) · ba74791b
      Bastian Köcher authored
      * Improve collator side of the collator-protocol
      
      This pr improves the collator-protocol implementation of the collator
      side. Besides cleaning up code and rewriting it, the following changed:
      
      - Before on `PeerViewChange` we send an advertisment to every peer, now
      this only happens for validators.
      - It also adds a check that we send an advertisment message only once
      for a connected peer.
      - If the same validator was part of the current and next group, we
      requested to be connected to this validator two times. This is also
      fixed now.
      - Instead of having only one connection request, we now are being able
      to store multiple of them. This is required as we can have multiple
      active leafs at any point of time.
      
      * Switch to common `ConnectionRequests`
      
      * Update node/network/collator-protocol/src/collator_side.rs

      Adds test parachain adder collator (#1864) · 8cadebb7
      Bastian Köcher authored
      
      
      * start working on building the real overseer
      
      Unfortunately, this fails to compile right now due to an upstream
      failure to compile which is probably brought on by a recent upgrade
      to rustc v1.47.
      
      * fill in AllSubsystems internal constructors
      
      * replace fn make_metrics with Metrics::attempt_to_register
      
      * update to account for #1740

      * add 'static bounds to real_overseer type params
      
      * pass authority_discovery and network_service to real_overseer
      
      It's not straightforwardly obvious that this is the best way to handle
      the case when there is no authority discovery service, but it seems
      to be the best option available at the moment.
      
      * select a proper database configuration for the availability store db
      
      * use subdirectory for av-store database path
      
      * apply Basti's patch which avoids needing to parameterize everything on Block
      
      * simplify path extraction
      
      * get all tests to compile
      
      * Fix Prometheus double-registry error
      
      for debugging purposes, added this to node/subsystem-util/src/lib.rs:472-476:
      
      ```rust
      Some(registry) => Self::try_register(registry).map_err(|err| {
      	eprintln!("PrometheusError calling {}::register: {:?}", std::any::type_name::<Self>(), err);
      	err
      }),
      ```
      
      That pointed out where the registration was failing, which led to
      this fix. The test still doesn't pass, but it now fails in a new
      and different way!
      
      * authorities must have authority discovery, but not necessarily overseer handlers
      
      * fix broken SpawnedSubsystem impls
      
      detailed logging determined that using the `Box::new` style of
      future generation, the `self.run` method was never being called,
      leading to dropped receivers / closed senders for those subsystems,
      causing the overseer to shut down immediately.
      
      This is not the final fix needed to get things working properly,
      but it's a good start.
      
      * use prometheus properly
      
      Prometheus lets us register simple counters, which aren't very
      interesting. It also allows us to register CounterVecs, which are.
      With a CounterVec, you can provide a set of labels, which can
      later be used to filter the counts.
      
      We were using them wrong, though. This pattern was repeated in a
      variety of places in the code:
      
      ```rust
      // panics with an cardinality mismatch
      let my_counter = register(CounterVec::new(opts, &["succeeded", "failed"])?, registry)?;
      my_counter.with_label_values(&["succeeded"]).inc()
      ```
      
      The problem is that the labels provided in the constructor are not
      the set of legal values which can be annotated, but a set of individual
      label names which can have individual, arbitrary values.
      
      This commit fixes that.

      * Make sure validator discovery works with a delayed peer to validator mapping
      
      Currently the implementation checks on connect of a peer if this peer is
      a validator by asking the authority discovery. It can now happen that
      the authority discovery is not yet aware that a given peer is an
      authority. This can for example happen on start up of the node.
      
      This pr changes the behavior, to make it possible to later associate a
      peer to a validator id. Instead of just storing the connected
      validators, we now store all connected peers with a vector of associated
      validator ids. When we get a request to connect to a given given set of
      validators, we start by checking the connected peers. If we didn't find
      a validator id in the connected peers, we ask the authority discovery
      for the peerid of a given authority id. When the returned peerid is part
      of our connected peers set, we cache and return the authority id.

      With a CounterVec, you can provide a set of labels, which can
      later be used to filter the counts.
      
      We were using them wrong, though. This pattern was repeated in a
      variety of places in the code:
      
      ```rust
      // panics with an cardinality mismatch
      let my_counter = register(CounterVec::new(opts, &["succeeded", "failed"])?, registry)?;
      my_counter.with_label_values(&["succeeded"]).inc()
      ```
      
      The problem is that the labels provided in the constructor are not
      the set of legal values which can be annotated, but a set of individual
      label names which can have individual, arbitrary values.
      
      This commit fixes that.

      Make collation an optional return (#1787) · ce0fa3ad
      Bastian Köcher authored
      This pr changes the collator interface function to return an optional
      collation instead of a collation. This is required as the parachain
      itself can fail to generate a valid collation for various reason. Now if
      the collation fails it will return `None`.
      
      Besides that the pr adds some `RuntimeDebug` derive for `ValidationData`
      and removes some whitespaces.
