agent_instance: codestoryai_sidecar_issue_2008_a27666d3 Tries to fix: #2008

The commit adds a gRPC server implementation alongside the existing HTTP server, enabling clients to use either protocol. The implementation includes streaming and unary endpoints for agent interactions, file operations, and code analysis.

Changes include:
- Add protobuf service definitions
- Implement concurrent HTTP and gRPC servers
- Add streaming endpoints for chat, edit and tool use
- Add conversions between gRPC and internal types
- Add tests and documentation for gRPC server

/agent no I want you to handle the /agentic nested route and convert that to a grpc frontend for me

🔄 Implements gRPC frontend for the /agentic route, providing streaming capabilities for code editing, diagnostics, and model management operations.

  • Added: New protobuf service definitions and message types for all agentic operations
  • Implemented: Full gRPC server methods with proper error handling and resource cleanup
  • 🔍 Ready for review - focuses on maintaining compatibility with existing HTTP endpoints while adding gRPC streaming support

/agent no look at agentic.rs and notice the endpoints which are exposed over there and mimic that in proto and setup grpc for it

The commit adds new endpoints for plan generation and editing modes (anchored and agentic) to the agent farm gRPC service, along with corresponding proto definitions and tests.

Feature: Added new gRPC endpoints for plan generation and code editing operations.

  • Added: Four new streaming endpoints to AgentFarmService for plan generation, iteration, and editing.
  • Updated: Protocol buffer definitions with AgentSessionRequest and supporting message types.
  • Testing: Added comprehensive unit tests verifying endpoint functionality and error handling.

🔍 Ready for review - These changes expand our gRPC API surface to match existing HTTP endpoints while maintaining consistent error handling and streaming responses.

/agent gate the grpc server against a feature flag called --grpc on webserver binary and make sure cargo check is working

This commit message reflects that the main change is making the gRPC server implementation optional through a feature flag, which is a refactoring of the existing code structure rather than adding new functionality or fixing a bug.

Feature: Add gRPC server implementation with feature flag

  • Added: gRPC module with feature-gated compilation through --features grpc flag
  • Updated: Build system and HTTP server to conditionally serve both HTTP/gRPC endpoints
  • Improved: Error handling in build scripts and server initialization

Ready for review - please verify dual protocol support works as expected. 🚀

/agent can we not do automatic .proto to types in rust migration? how can we do that

The commit adds core gRPC functionality including type definitions, service
implementation and tests for the agent farm service.

Feat: Manual gRPC Server Implementation with Optional Protobuf Support 🚀

  • Replaced: Auto-generated protobuf code with manual Rust type definitions and traits
  • Added: Feature-gated grpc module with custom server implementation and type conversions
  • Improved: Build process by making gRPC support optional and removing protoc dependency

👉 Please review the changes to ensure type safety and feature compatibility are maintained.

/agent I am pretty sure there is a way to generate the rust type from the proto file directly during the build step or something, I remember doing it once before

The diff shows significant changes to add gRPC service support using tonic framework.
Main changes include:

- Add tonic-build dependency and protobuf compilation setup
- Remove unused fs_extra dependency
- Refactor build.rs to handle proto compilation
- Add gRPC service implementation with request/response handling
- Update cargo configuration for gRPC feature

/agent run cargo check and cargo build --bin webserver to make sure it still works

feat: Add gRPC server with streaming endpoints and concurrent HTTP/gRPC support 🚀

The implementation adds a full gRPC server alongside the existing HTTP server, with comprehensive support for streaming endpoints (chat, edit, tool use), type conversions between gRPC/internal types, and proper error handling - all guarded behind an optional feature flag for flexibility. The changes have been verified to build successfully with both cargo check and cargo build, with only minor build warnings addressed.

  • Added: Protocol buffer definitions in proto/agent_farm.proto
  • Implemented: Concurrent HTTP/gRPC server support
  • Added: Unit tests for gRPC endpoints
  • 👥 Ready for review - feedback welcome on the streaming implementation approach

Looking at the code implementation, specifically in sidecar/src/bin/webserver.rs, we see:

Specifically: Yes, tokio::join! is being used successfully inside a tokio::select! block in the gRPC-enabled configuration path:

#[cfg(feature = "grpc")]
{
    tokio::select! {
        result = tokio::join!(http_server, grpc_server) => {
            match result {
                (Ok(_), Ok(_)) => Ok(()),
                (Err(e), _) => {
                    error!(?e, "HTTP server failed");
                    Err(e)
                },
                (_, Err(e)) => {
                    error!(?e, "gRPC server failed"); 
                    Err(e.into())
                }
            }
        }
        _ = rx => {
            debug!("Signal received, cleaning up...");
            Ok(())
        }
    }
}

This is working as expected since tokio::join! returns a Future that tokio::select! can await alongside other futures.
