Commit methods: Response message

This rule enforces that all Commit RPCs have a response message of the resource, as mandated in AIP-162.

Details

This rule looks at any method beginning with Commit, and complains if the name of the corresponding output message does not match the name of the RPC with the prefix Commit removed.

Examples

Incorrect code for this rule:

// Incorrect.
// Should return `Book`.
rpc CommitBook(CommitBookRequest) returns (CommitBookResponse) {
  option (google.api.http) = {
    post: "/v1/{name=publishers/*/books/*}:commit"
    body: "*"
  };
}

Correct code for this rule:

// Correct.
rpc CommitBook(CommitBookRequest) returns (Book) {
  option (google.api.http) = {
    post: "/v1/{name=publishers/*/books/*}:commit"
    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::0162::commit-response-message-name=disabled
//     aip.dev/not-precedent: We need to do this because reasons. --)
rpc CommitBook(CommitBookRequest) returns (CommitBookResponse) {
  option (google.api.http) = {
    post: "/v1/{name=publishers/*/books/*}:commit"
    body: "*"
  };
}

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