* .maintain: Replace sentry-node with local-docker-test-network
Sentry nodes are deprecated. Thus there is no need for
`.maintain/sentry-node` to spin up a sentry node test environment.
Instead this commit rewrites the setup to contain two full-connected
validators and one light client.
With the steps below one can now spin up a local test network with
two validators, one light-client, Prometheus and Grafana.
- cargo build --release
- sudo docker-compose -f .maintain/local-docker-test-network/docker-compose.yml up
* client/network/light: Handle oneshot cancellation
* client/network/light: Do not reduce retry count on missing peer
* client/network/request-response: Assert in debug request id to be unique
* client/network/light: Choose same limit as block request protocol
* client/network: Report reputation changes via response
Allow request response protocol handlers to issue reputation changes, by
sending them back along with the response payload.
* client/network: Remove resolved TODOs
* Fix tracing spans are not being forwarded to spawned task
There is a bug that tracing spans are not forwarded to spawned task. The
problem was that only the telemetry span was forwarded. The solution to
this is to use the tracing provided `in_current_span` to capture the
current active span and pass the telemetry span explictely. We will now
always enter the span when the future is polled. This is essentially the
same strategy as tracing is doing with its `Instrumented`, but now
extended for our use case with having multiple spans active.
* More tests
* Block announce validation should use the correct `Validation` result
The error variant is just for internal errors and we need to return
`Failure` always when the other node send us an invalid statement.
* Update network/src/lib.rs

* Sync: Fix issue of not freeing a block announcement slot
There was a bug that when the block announcement validation returned an
error, the slot reserved for this validation wasn't freed. This could
lead to a situation where we rejected any block announcement from such a
peer for that the block announcement returned an error multiple times.
* Better logging
* Fuck I'm dumb
* 🤦
This changes the collator to print an error if the block that we can not
find is the genesis block, instead of only logging this as a `debug`
message. This should help people when they have registered the wrong
genesis state on the relay chain.
* Clarify and expand docs.

* Introduce a `Slot` type
Instead of having some type definition that only was used in half of the
code or directly using `u64`, this adds a new unit type wrapper `Slot`.
This makes it especially easy for the outside api to know what type is
expected/returned.
* Change epoch duratioC
* rename all instances of slot number to slot
* Make the constructor private

* use proper descriptive generic type names
* cleanup
* Table stores a list of detected misbehavior per authority
* add Table::drain_misbehaviors_for
* WIP: unify misbehavior types; report multiple misbehaviors per validator
Code checks, but tests don't yet pass.
* update drain_misbehaviors: return authority id as well as specific misbehavior
* enable unchecked construction of Signed structs in tests
* remove test-features feature & unnecessary generic
* fix backing tests
This took a while to figure out, because where we'd previously been
passing around `SignedFullStatement`s, we now needed to construct
those on the fly within the test, to take advantage of the signature-
checking in the constructor. That, in turn, necessitated changing the
iterable type of `drain_misbehaviors` to return the validator index,
and passing that validator index along within the misbehavior report.
Once that was sorted, however, it became relatively straightforward:
just needed to add appropriate methods to deconstruct the misbehavior
reports, and then we could construct the signed statements directly.
* fix bad merge
* client/network: Report reputation changes via response
When handling a request by a remote peer in a request response handler,
one might want to in- or de-crease the reputation of the peer. E.g. one
might want to decrease the reputation slightly for each request, given
that it forces the local node to do work, or one might want to issue a
larger reputation change due to a malformed request by the remote peer.
Instead of having to pass a peerset handle to each request response
handler, this commit suggests to allow handlers to isssue reputation
changes via the provided `pending_response` `oneshot` channel.
A reputation change issued by a request response handler via the
`pending_response` channel is received by the
`RequestResponsesBehaviour` which passes the reputation change up as an
event to eventually be send to a peerset via a peerset handle.
* client/network/req-resp: Use Vec::new instead of None::<Vec<_>>
* client/network: Rename Response to OutgoingResponse
Given that a request-response request is not called `Request` but
`InomingRequest`, rename a request-response response to
`OutgoingResponse`.
