Nicholas	610cf02c4a	rpc: improve error codes for internal server errors (#25678) ... This changes the error code returned by the RPC server in certain situations: - handler panic: code -32603 - result marshaling error: code -32603 - attempt to subscribe via HTTP: code -32001 In all of the above cases, the server previously returned the default error code -32000.

Seungbae Yu	38e002f464	rpc: check that "version" is "2.0" in request objects (#25570) ... The JSON-RPC spec requires the "version" field to be exactly "2.0", so we should verify that. This change is not backwards-compatible with sloppy client implementations, but I decided to go ahead with it anyway because the failure will be caught via the returned error.	2 years ago

Felix Lange	245f3146c2	rpc: implement full bi-directional communication (#18471) ... New APIs added: client.RegisterName(namespace, service) // makes service available to server client.Notify(ctx, method, args...) // sends a notification ClientFromContext(ctx) // to get a client in handler method This is essentially a rewrite of the server-side code. JSON-RPC processing code is now the same on both server and client side. Many minor issues were fixed in the process and there is a new test suite for JSON-RPC spec compliance (and non-compliance in some cases). List of behavior changes: - Method handlers are now called with a per-request context instead of a per-connection context. The context is canceled right after the method returns. - Subscription error channels are always closed when the connection ends. There is no need to also wait on the Notifier's Closed channel to detect whether the subscription has ended. - Client now omits "params" instead of sending "params": null when there are no arguments to a call. The previous behavior was not compliant with the spec. The server still accepts "params": null. - Floating point numbers are allowed as "id". The spec doesn't allow them, but we handle request "id" as json.RawMessage and guarantee that the same number will be sent back. - Logging is improved significantly. There is now a message at DEBUG level for each RPC call served.	6 years ago
