Peter Goodspeed-Niklaus 14ce04c9cd signed wrapper (#1283)
* add signed wrapper, typedef SignedStatement

* typedef SignedAvailabilityBitfield

* implement Signed wrapper

This is strictly an addition as of this commit; nothing is yet
changed in existing behavior.

* inline getters, remove review comment

* move EncodeAs, Signed from node::primitives to primitives::parachain

* Refactor SignedAvailabilityBitfield to use Signed

* don't double-encode real payload

This isn't an ideal solution, because it depends on the
implementation details of how SCALE encodes tuples, but OTOH
that behavior seems unlikely to change anytime soon.

* fix build errors

* cause the runtime to build properly with the new changes

Not sure why cargo check didn't catch this earlier; oh well.

* fix runtime tests and separate SignedStatement from SignedFullStatement

* better explain why CompactStatement exists

Bastian Köcher c712bbb0d9 Add some logging to the validation pipeline. (#1278) 2020-06-17 15:08:54 -04:00
Bastian Köcher c04c88d71e Keep the table router for the lifetime of the validation instance alive (#1175)
This pr ensures that the table router stays alive for the lifetime of
the validation instance. This is required to ensure that the node
responds onto gossip messages for the particular relay chain round.
Before, the table router was only kept alive for relay chain nodes that
were assigned to a Parachain, however the lifetime was also relative
short. This lead to bugs where a relay chain node did not include
PoVBlock's, because it did not receive them (rejected them on receive,
because it was not listening on the particular round).

Bastian Köcher c021f854a2 Ensure that table router is always built (#952)
* Ensure that table router is always build

This pr ensures that the table router is always build, aka the future is
resolved. This is important, as the table router internally spawns tasks
to handle gossip messages. Handling gossip messages is not only required
on parachain validators, but also on relay chain validators to receive collations.

Tests are added to ensure that the assumptions hold.

* Flag to force kusama runtime

* Chainspecs for kusama

* Polkadot config for westend

Co-Authored-By: Bastian Köcher <bkchr@users.noreply.github.com>

* network/src/legacy/gossip: Wrap GossipEngine in Arc Mutex & lock it on use

`GossipEngine` in itself has no need to be Send and Sync, given that it
does not rely on separately spawned background tasks anymore.
`RegisteredMessageValidator` needs to be `Send` and `Sync` due to the
inherited trait bounds from implementing `GossipService`. In addition
`RegisteredMessageValidator` derives `Clone`. Thereby `GossipEngine`
needs to be wrapped in an `Arc` and `Mutex` to keep the status quo.

* Needed fixes.

* Fixes

* Fixed build

* Fixed build w benchmarking CLI

* Fixed building tests

* Added --dev shortcut

* service/src/lib.rs: Register network event stream for authority disc

Previously one would create a sender and receiver channel pair, pass the
sender to the build_network_future through the service builder and
funnel network events returned from polling the network service into the
sender to be consumed by the authority discovery module owning the
receiver.

With recent changes it is now possible to register an event_stream
with the network service directly, thus one does not need to make the
detour through the build_network_future.

This commit is an adjusted clone of one targeting the Substrate
repository.

* service/src/lib.rs: Register network event stream for authority disc

Previously one would create a sender and receiver channel pair, pass the
sender to the build_network_future through the service builder and
funnel network events returned from polling the network service into the
sender to be consumed by the authority discovery module owning the
receiver.

With recent changes it is now possible to register an event_stream
with the network service directly, thus one does not need to make the
detour through the build_network_future.

This commit is an adjusted clone of one targeting the Substrate
repository.
