client: Do not set fork sync request via network-gossip#4439
Merged
Conversation
The finality-grandpa module needs two sets of functionalities from the network: 1. Everything gossip related, e.g. event_stream, write_notification, ... 2. The ability to set a fork sync request for a specific block hash. Instead of embedding (2) inside of (1) this patch extracts (2) from (1) having finality-grandpa depend on a `Network` that fulfills the `network_gossip::Network` trait and that can set block sync requests. On the one hand this improves the overall structure splitting things that don't logically belong together. On the other hand it does reintroduce a lot of trait bounds within finality-grandpa.

I don't we can work around this, the split makes sense to me. LGTM
