Delete Revision methods: POST HTTP verb

This rule enforces that all Delete Revision RPCs use the DELETE HTTP verb, as mandated in AIP-162.

Details

This rule looks at any method matching Delete*Revision, and complains if the HTTP verb is anything other than DELETE. It does check additional bindings if they are present.

Examples

Incorrect code for this rule:

// Incorrect.
rpc DeleteBookRevision(DeleteBookRevisionRequest) returns (google.protobuf.Empty) {
  option (google.api.http) = {
    post: "/v1/{name=publishers/*/books/*}:deleteRevision"  // Should be `delete:`.
  };
}

Correct code for this rule:

// Correct.
rpc DeleteBookRevision(DeleteBookRevisionRequest) returns (google.protobuf.Empty) {
  option (google.api.http) = {
    delete: "/v1/{name=publishers/*/books/*}:deleteRevision"
  };
}

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::delete-revision-http-method=disabled
//     aip.dev/not-precedent: We need to do this because reasons. --)
rpc DeleteBookRevision(DeleteBookRevisionRequest) returns (google.protobuf.Empty) {
  option (google.api.http) = {
    post: "/v1/{name=publishers/*/books/*}:deleteRevision"
  };
}

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