Draft: Add RequestMetadataGenerator constructor for ServerContext and getter method
Before raising this MR, consider whether the following are required, and complete if so:
-
Unit tests
If not required, please explain in brief why not.
Description
This PR adds additional functionality to the RequestMetadataGenerator
class to facilitate forwarding RequestMetadata
from clients -> upstream servers in buildbox-casd
. It adds a new constructor which takes a std::multimap<grpc::string_ref, grpc::string_ref>
as input, which is how grpc::ServerContext.client_metadata()
returns metadata sent from the client, and use that RequestMetadata
to initialize itself. The second method is a getter which returns the RequestMetadata
that the RequestMetadataGenerator
would generate, which is useful both for testing and for buildbox-casd
/ other possible servers to get access to the RequestMetadata
for display or other purposes.
Changes proposed in this merge request:
- Add new constructor to
RequestMetadataGenerator
- Add
get_request_metadata
method
Validation
This functionality is tested by the tests
