Moved non-agent-specific logic from agent/pkg/agent/ to internal/agentpool/:
- pool.go: Agent pool management (Get, Add, Remove, List, Iter, etc.)
- http_requests.go: HTTP utilities (health checks, forwarding, websockets, reverse proxy)
- agent.go: Agent struct with HTTP client management
This separates general-purpose pool management from agent-specific configuration,
improving code organization and making the agent package focused on agent config only.
- Enhanced error handling in the UDP server to properly manage EOF and closed connection scenarios.
- Ensured that bytes read from the client are forwarded before handling errors.
- Added checks to avoid logging noise for expected shutdown conditions.
- Adjusted headerSize calculation to reflect the correct size based on field definitions.
- Changed HostLength and PortLength types from uint8 to byte.
- Updated PROTOCOL.md to reflect the new header size and structure.
- Updated error handling in the UDP server to ignore io.EOF errors when reading from client connections.
- Added a check to return early if no bytes are read from the client connection.
- Ensured proper closure of tcpListener in the main.go file during cancellation.
- Removed the streamServerAddr field from AgentConfig to streamline configuration.
- Updated StartWithCerts, NewTCPClient, and NewUDPClient methods to use Addr directly for establishing connections.
- Eliminated the getStreamServerAddr method as it is no longer needed.
- Use agent.NewAgent() for properly configured certificates matching real usage
- Migrate to testify/require for assertions
- Add tests for UDP server rejecting clients with invalid certificates
- Use t.Context() for lifecycle management
- Add `StreamPort` configuration to agent configuration and environment variables
- Implement TCP and UDP stream client support in agent package
- Update agent verification to test stream connectivity (TCP/UDP)
- Add `/info` endpoint to agent HTTP handler for version, name, runtime, and stream port
- Remove /version, /name, /runtime APIs, replaced by /info
- Update agent compose template to expose stream port for TCP and UDP
- Update agent creation API to optionally specify stream port (defaults to port + 1)
- Modify `StreamRoute` to pass agent configuration to stream implementations
- Update `TCPTCPStream` and `UDPUDPStream` to use agent stream tunneling when agent is configured
- Add support for both direct connections and agent-tunneled connections in stream routes
This enables agents to handle TCP and UDP route tunneling, expanding the proxy capabilities beyond HTTP-only connections.
- Introduced ReverseProxy method to handle requests to the agent with context, method, and body.
- Updated Forward method to return *http.Response instead of byte data.
- Enhanced SystemInfo function to support querying by agent name in addition to agent address.
- Introduced ContainerRuntime field in AgentConfig and AgentEnvConfig.
- Added IterAgents and NumAgents functions for agent pool management.
- Updated agent creation and verification endpoints to handle container runtime.
- Enhanced Docker Compose template to support different container runtimes.
- Added runtime endpoint to retrieve agent runtime information.
- These changes makes the API incombatible with previous versions
- Added new types for error handling, success responses, and health checks.
- Updated health check logic to utilize the new types for better clarity and structure.
- Refactored existing handlers to improve response consistency and error handling.
- Updated Makefile to include a new target for generating API types from Swagger.
- Updated "new agent" API to respond an encrypted cert pair
