Pass all parameters from JSON-RPC requests to their corresponding handlers using struct types instead of positional parameters. This allows us to control encoding of arguments using only the standard library, and to eliminate the remaining special-purpose JSON encoding hooks in the server. To support existing use, the server still allows arguments to be encoded in JSON as either an array or an object. Related changes: - Rework the RPCFunc constructor to reduce reflection during RPC call service. - Add request parameter wrappers for each RPC service method. - Update the RPC Environment methods to use these types. - Update the interfaces and shims derived from Environment to the new signatures. - Update and extend test cases.
Tendermint RPC
Pagination
Requests that return multiple items will be paginated to 30 items by default. You can specify further pages with the ?page parameter. You can also set a custom page size up to 100 with the ?per_page parameter.
Subscribing to events
The user can subscribe to events emitted by Tendermint, using /subscribe. If
the maximum number of clients is reached or the client has too many
subscriptions, an error will be returned. The subscription timeout is 5 sec.
Each subscription has a buffer to accommodate short bursts of events or some
slowness in clients. If the buffer gets full, the subscription will be canceled
("client is not pulling messages fast enough"). If Tendermint exits, all
subscriptions are canceled ("Tendermint exited"). The user can unsubscribe
using either /unsubscribe or /unsubscribe_all.
