gary rong	be9172a7ac	rpc: metrics for JSON-RPC method calls (#20847) ... This adds a couple of metrics for tracking the timing and frequency of method calls: - rpc/requests gauge counts all requests - rpc/success gauge counts requests which return err == nil - rpc/failure gauge counts requests which return err != nil - rpc/duration/all timer tracks timing of all requests - rpc/duration/<method>/<success/failure> tracks per-method timing	5 years ago
Felix Lange	8008c5b1fa	rpc: remove 'exported or builtin' restriction for parameters (#20332) ... * rpc: remove 'exported or builtin' restriction for parameters There is no technial reason for this restriction because package reflect can create values of any type. Requiring parameters and return values to be exported causes a lot of noise in package exports. * rpc: fix staticcheck warnings	5 years ago
Felix Lange	7c4a4eb58a	rpc, p2p/simulations: use github.com/gorilla/websocket (#20289) ... * rpc: improve codec abstraction rpc.ServerCodec is an opaque interface. There was only one way to get a codec using existing APIs: rpc.NewJSONCodec. This change exports newCodec (as NewFuncCodec) and NewJSONCodec (as NewCodec). It also makes all codec methods non-public to avoid showing internals in godoc. While here, remove codec options in tests because they are not supported anymore. * p2p/simulations: use github.com/gorilla/websocket This package was the last remaining user of golang.org/x/net/websocket. Migrating to the new library wasn't straightforward because it is no longer possible to treat WebSocket connections as a net.Conn. * vendor: delete golang.org/x/net/websocket * rpc: fix godoc comments and run gofmt	5 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
