* Rough skeleton for what I think the RPC should look like * Create channel for sending justifications Sends finalized header and justification from Grandpa to the client. This lays the groundwork for hooking into the RPC module. * WIP: Add subscribers for justifications to Grandpa Adds the Sender end of a channel into Grandpa, through which notifications about block finality events can be sent. * WIP: Add a struct for managing subscriptions Slightly different approach from the last commit, but same basic idea. Still a rough sketch, very much doesn't compile yet. * Make naming more clear and lock data in Arc * Rough idea of what RPC would look like * Remove code from previous approach * Missed some things * Update client/rpc-api/src/chain/mod.rs Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * Update client/rpc-api/src/chain/mod.rs Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com> * Split justification subscription into sender and receiver halves * Replace RwLock with a Mutex * Add sample usage from the Service's point of view * Remove code that referred to "chain_" RPC * Use the Justification sender/receivers from Grandpa LinkHalf * Add some PubSub boilerplate * Add guiding comments * TMP: comment out to fix compilation * Return MetaIoHandler from PubSubHandler in create_full * Uncomment pubsub methods in rpc handler (fails to build) * node/rpc: make Metadata concrete in create_full to fix compilation * node: pass in SubscriptionManger to grandpa rpc handler * grandpa-rpc: use SubscriptionManger to add subscriber * grandpa-rpc: attempt at setting up the justification stream (fails to build) * grandpa-rpc: fix compilation of connecting stream to sink * grandpa-rpc: implement unsubscribe * grandpa-rpc: update older tests * grandpa-rpc: add full prefix to avoid confusing rust-analyzer * grandpa-rpc: add test for pubsub not available * grandpa-rpc: tidy up leftover code * grandpa-rpc: add test for sub and unsub of justifications * grandpa-rpc: minor stylistic changes * grandpa-rpc: split unit test * grandpa-rpc: minor stylistic changes in test * grandpa-rpc: skip returning future when cancelling * grandpa-rpc: reuse testing executor from sc-rpc * grandpa-rpc: don't need to use PubSubHandler in tests * node-rpc: use MetaIoHandler rather than PubSubHandler * grandpa: log if getting header failed * grandpa: move justification channel creation into factory function * grandpa: make the justification sender optional * grandpa: fix compilation warnings * grandpa: move justification notification types to new file * grandpa-rpc: move JustificationNotification to grandpa-rpc * grandpa-rpc: move JustificationNotification to its own file * grandpa: rename justification channel pairs * grandpa: rename notifier types * grandpa: pass justification as GrandpaJustification to the rpc module * Move Metadata to sc-rpc-api * grandpa-rpc: remove unsed error code * grandpa: fix bug for checking if channel is closed before sendind * grandpa-rpc: unit test for sending justifications * grandpa-rpc: update comments for the pubsub test * grandpa-rpc: update pubsub tests with more steps * grandpa-rpc: fix pubsub test * grandpa-rpc: minor indendation * grandpa-rpc: decode instead of encode in test * grandpa: fix review comments * grandpa: remove unused serde dependency Co-authored-by: Tomasz Drwięga <tomusdrw@users.noreply.github.com> Co-authored-by: Jon Häggblad <jon.haggblad@gmail.com> Co-authored-by: Tomasz Drwięga <tomasz@parity.io>
