* Change copyright year to 2023 from 2022
* Fix incorrect update of copyright year
* Remove years from copy right header
* Fix remaining files
* Fix typo in a header and remove update-copyright.sh
* #10576: refactor `sc-utils::notification` and `sc-client-api::notifications`, so that they use common subscribe/unsubscribe routines
* Add some docs. Reorganise `sc-utils::notification`
* `sc-clent-api::notifications` and `sc-utils::notification` — ensure the SubscriptionGuard is dropped before the Rx-channel
* `sc-utils::pubsub::SubscriptionGuard` make it a bit more ergonomic.
Let the `Rx` to be put inside of the `SubscriptionGuard`, so that the latter shall guarantee the order:
- first unsubscribe;
- then drop the `Rx`.
* Being less zealous with splitting the modules into little pieces
* rework pubsub: the concrete usage should only define a good registry type
* sc-client-api::notifications: make it comply with the reworked pubsub
* cargo fmt
* make sc-client-api tests work
* Address the review notes
* cargo fmt
* Describe the behaviour of pubsub registry
* Doc-comments for module `sc-utils::pubsub`
* Fix: it used to send notifications regardless of the filter setup during subscription
* `sc-client-api::StorageNotifications` the API does not have to require mut-self-reference.
As a result `sc-service::Client` does not have to wrap its `storage_notifications` into a Mutex.
* cargo fmt
* Several changes addressing the notes by @bckhr.
- Remove the `impl Default for StorageNotifications<Block>`;
- no need for groupping the `remove_from` and `listen_from` into a separate `helpers` module;
- remove unnecessary import `use registry::SubscribeOp`.
* Add a doc-comment to the `sc-client::notifications::SubscribeOp`
* As per @bkchr note on the unproven assertion: behave gracefully upon receiving a duplicate subscription-ID.
* sc-utils::pubsub: log when a registry yields an ID that does point to an existing sink
* `sc-utils::notifications`: payload materialized lazily
* Update Cargo.lock (after adding `log` as a dependency to the `sc-utils`)
* `sc-client-api::notifications`: introduce a struct (instead of a type def) for the notification message
* Get rid of `sc-utils::pubsub::Channel` trait (instead just use the `sc-utils::mpsc`)
* The SubsID is no more generic: the fact it is a `Copy` is known — no need to pass it by ref
* sc-utils::pubsub internals do not have to be generic over the channel type
* Rename Hub::dispatch into Hub::send
* That method was unnecessary (`SubscriberSink::render_notification`)
* cargo fmt
* No need for a separate UnsubscribeGuard type
* Ditch the type-def of SubsID in the sc-utils::pubsub, instead — just use the crate::id_sequence::SeqID
* Return the <Registry as Dispatch>::Ret when sending an item
* Make the `Hub<M, R>::lock_registry(...)` method more ergonomic
* cargo doc links
* cargo doc links
* Use a simpler name for the type
* cargo doc links
* Derive `Default` rather than implement it
* Derive `Default` rather than implement it
* Remove an unnecessary usage of type_name
* Define a more cautious order between sinks.remove->registry.unsubscribe and registry.subscribe->sinks.insert
* Hub: lock_registry_for_tests->map_registry_for_tests — a safer choice for a public API
* Replace Mutex over the shared Registry with a ReentrableMutex+RefCell
* sc-utils::pubsub: add tests for a panicking registry
* Add the missing copyright headers
* Arc<Vec<_>> -> Arc<[_]>
* beefy: add dummy latest_finalized() RPC
* beefy: rpc latest_best_beefy() using shared mem
* beefy: rpc populate latest_best_beefy()
* beefy: rpc handle readiness
* beefy: best block over channel - wip
Not working because channel can't be simply opened and receiver passed
to `rpc_extensions_builder` because `rpc_extensions_builder` has to be
`Fn` and not `FnOnce`... and and Receiver side of mpsc can't be cloned
yay!..
