The +client-to-server health checking can happen from point to point or via some +control system. A server may choose to reply “unhealthy” because it +is not ready to take requests, it is shutting down or some other reason. +The client can act accordingly if the response is not received within some time +window or the response says unhealthy in it. + + +A GRPC service is used as the health checking mechanism for both simple +client-to-server scenario and other control systems such as load-balancing. +Being a high +level service provides some benefits. Firstly, since it is a GRPC service +itself, doing a health check is in the same format as a normal rpc. Secondly, +it has rich semantics such as per-service health status. Thirdly, as a GRPC +service, it is able reuse all the existing billing, quota infrastructure, etc, +and thus the server has full control over the access of the health checking +service. + +## Service Definition + +The server should export a service defined in the following proto: + +``` +syntax = "proto3"; + +package grpc.health.v1alpha; + +message HealthCheckRequest { + string service = 1; +} + +message HealthCheckResponse { + enum ServingStatus { + UNKNOWN = 0; + SERVING = 1; + NOT_SERVING = 2; + } + ServingStatus status = 1; +} + +service Health { + rpc Check(HealthCheckRequest) returns (HealthCheckResponse); +} +``` + +A client can query the server’s health status by calling the `Check` method, and +a deadline should be set on the rpc. The client can optionally set the service +name it wants to query for health status. The suggested format of service name +is `package_names.ServiceName`, such as `grpc.health.v1alpha.Health`. + +The server should register all the services manually and set +the individual status, including an empty service name and its status. For each +request received, if the service name can be found in the registry, +a response must be sent back with an `OK` status and the status field should be +set to `SERVING` or `NOT_SERVING` accordingly. If the service name is not +registered, the server returns a `NOT_FOUND` GRPC status. + +The server should use an empty string as the key for server’s +overall health status, so that a client not interested in a specific service can +query the server's status with an empty request. The server can just do exact +matching of the service name without support of any kind of wildcard matching. +However, the service owner has the freedom to implement more complicated +matching semantics that both the client and server agree upon. + +A client can declare the server as unhealthy if the rpc is not finished after +some amount of time. The client should be able to handle the case where server +does not have the Health service. diff --git a/include/grpc++/auth_context.h b/include/grpc++/auth_context.h index c42105b927..f8ea8ad6f4 100644 --- a/include/grpc++/auth_context.h +++ b/include/grpc++/auth_context.h @@ -34,12 +34,42 @@ #ifndef GRPCXX_AUTH_CONTEXT_H #define GRPCXX_AUTH_CONTEXT_H +#include <iterator> #include <vector> -#include <grpc++/auth_property_iterator.h> #include <grpc++/config.h> +struct grpc_auth_context; +struct grpc_auth_property; +struct grpc_auth_property_iterator; + namespace grpc { +class SecureAuthContext; + +typedef std::pair<grpc::string, grpc::string> AuthProperty; + +class AuthPropertyIterator + : public std::iterator<std::input_iterator_tag, const AuthProperty> { + public: + ~AuthPropertyIterator(); + AuthPropertyIterator& operator++(); + AuthPropertyIterator operator++(int); + bool operator==(const AuthPropertyIterator& rhs) const; + bool operator!=(const AuthPropertyIterator& rhs) const; + const AuthProperty operator*(); + + protected: + AuthPropertyIterator(); + AuthPropertyIterator(const grpc_auth_property* property, + const grpc_auth_property_iterator* iter); + private: + friend class SecureAuthContext; + const grpc_auth_property* property_; + // The following items form a grpc_auth_property_iterator. + const grpc_auth_context* ctx_; + size_t index_; + const char* name_; +}; class AuthContext { public: diff --git a/include/grpc/grpc.h b/include/grpc/grpc.h index 2471a0937e..f104648011 100644 --- a/include/grpc/grpc.h +++ b/include/grpc/grpc.h @@ -181,7 +181,9 @@ typedef enum grpc_call_error { GRPC_CALL_ERROR_INVALID_MESSAGE, /** completion queue for notification has not been registered with the server */ - GRPC_CALL_ERROR_NOT_SERVER_COMPLETION_QUEUE + GRPC_CALL_ERROR_NOT_SERVER_COMPLETION_QUEUE, + /** this batch of operations leads to more operations than allowed */ + GRPC_CALL_ERROR_BATCH_TOO_BIG } grpc_call_error; /* Write Flags: */ @@ -258,31 +260,44 @@ void grpc_call_details_destroy(grpc_call_details *details); typedef enum { /** Send initial metadata: one and only one instance MUST be sent for each - call, unless the call was cancelled - in which case this can be skipped */ + call, unless the call was cancelled - in which case this can be skipped. + This op completes after all bytes of metadata have been accepted by + outgoing flow control. */ GRPC_OP_SEND_INITIAL_METADATA = 0, - /** Send a message: 0 or more of these operations can occur for each call */ + /** Send a message: 0 or more of these operations can occur for each call. + This op completes after all bytes for the message have been accepted by + outgoing flow control. */ GRPC_OP_SEND_MESSAGE, /** Send a close from the client: one and only one instance MUST be sent from the client, unless the call was cancelled - in which case this can be - skipped */ + skipped. + This op completes after all bytes for the call (including the close) + have passed outgoing flow control. */ GRPC_OP_SEND_CLOSE_FROM_CLIENT, /** Send status from the server: one and only one instance MUST be sent from the server unless the call was cancelled - in which case this can be - skipped */ + skipped. + This op completes after all bytes for the call (including the status) + have passed outgoing flow control. */ GRPC_OP_SEND_STATUS_FROM_SERVER, /** Receive initial metadata: one and only one MUST be made on the client, - must not be made on the server */ + must not be made on the server. + This op completes after all initial metadata has been read from the + peer. */ GRPC_OP_RECV_INITIAL_METADATA, - /** Receive a message: 0 or more of these operations can occur for each call - */ + /** Receive a message: 0 or more of these operations can occur for each call. + This op completes after all bytes of the received message have been + read, or after a half-close has been received on this call. */ GRPC_OP_RECV_MESSAGE, /** Receive status on the client: one and only one must be made on the client. - This operation always succeeds, meaning ops paired with this operation - will also appear to succeed, even though they may not have.
