Batch Update methods: Response message

This rule enforces that all BatchUpdate RPCs have a response message name of BatchUpdate*Response, as mandated in AIP-234.

Details

This rule looks at any RPCs whose name starts with BatchUpdate, and complains if the name of the corresponding returned message does not match the name of the RPC with the suffix Response appended.

It also permits a response of google.longrunning.Operation; in this case, it checks the response_type in the google.longrunning.operation_info annotation and ensures that it corresponds to the name of the RPC with the suffix Response appended, as mandated in AIP-151.

Examples

Incorrect code for this rule:

// Incorrect.
// Should be `BatchUpdateBooksResponse`.
rpc BatchUpdateBooks(BatchUpdateBooksRequest) returns (BooksResponse) {
  option (google.api.http) = {
    post: "/v1/{parent=publishers/*}/books:batchUpdate"
    body: "*"
  };
}

Correct code for this rule:

// Correct.
rpc BatchUpdateBooks(BatchUpdateBooksRequest) returns (BatchUpdateBooksResponse) {
  option (google.api.http) = {
    post: "/v1/{parent=publishers/*}/books:batchUpdate"
    body: "*"
  };
}

Disabling

If you need to violate this rule, use a leading comment above the method. Remember to also include an aip.dev/not-precedent comment explaining why.

// (-- api-linter: core::0234::response-message-name=disabled
//     aip.dev/not-precedent: We need to do this because reasons. --)
rpc BatchUpdateBooks(BatchUpdateBooksRequest) returns (BooksResponse) {
  option (google.api.http) = {
    post: "/v1/{parent=publishers/*}/books:batchUpdate"
    body: "*"
  };
}

If you need to violate this rule for an entire file, place the comment at the top of the file.
