- add RetryWithBackoff helper to grpc client for exponential retry with backoff and reconnection-aware handling
- increase reconnectionClientTimeout to 90s and introduce connectionStabilizationDelay; wait briefly after reconnection to avoid immediate flapping
- refresh reconnection flag while waiting for client registration and improve cancellation message
- replace direct heartbeat RPC with RetryWithBackoff in WorkerService (use extended timeout)
- use RetryWithBackoff for worker node status updates in task handler and propagate errors
- master: add TIMING logs in setWorkerNodeOnline to mark start and completed DB update
- handler: log node status for reconnection debugging and include active/enabled values in "node not active or enabled" error
- Downgraded protoc-gen-go-grpc and protoc versions for compatibility.
- Added CheckProcess method to TaskService with corresponding request and response types.
- Updated Subscribe and Connect methods to use new generic client stream types.
- Refactored server and client implementations for Subscribe and Connect methods.
- Ensured backward compatibility by maintaining existing method signatures where applicable.
- Added necessary handler for CheckProcess in the service descriptor.
- Added logging for error handling in the MasterService when setting a worker node offline, replacing the previous trace.PrintError with a more informative log message.
- Enhanced WorkerService subscription method with debug logs to indicate subscription attempts and status, improving traceability during connection processes.
- Replaced all instances of apex/log with a structured logger interface in various services, including Api, Server, Config, and others, to enhance logging consistency and context.
- Updated logging calls to utilize the new logger methods, improving error tracking and service monitoring.
- Added logger initialization in services and controllers to ensure proper logging setup.
- Improved error handling and logging messages for better clarity during service operations.
- Removed unused apex/log imports and cleaned up related code for better maintainability.
- Removed direct usage of apex/log in favor of a structured logger interface for improved logging consistency and context.
- Updated logging calls in MasterService and WorkerService to utilize the new logger, enhancing error tracking and service monitoring.
- Added logger initialization in both services to ensure proper logging setup.
- Improved error handling and logging messages for better clarity during service operations.
- Added WaitForReady method to GrpcClient for blocking until the client is ready.
- Updated WorkerService to utilize WaitForReady for ensuring gRPC client readiness before starting.
- Refactored ModelService to consistently use GetGrpcClient for context management.
- Changed logging level for received metrics in MetricServiceServer from Info to Debug.
- Modified error handling in HandleError to conditionally print errors based on the environment.
- Cleaned up unused GrpcClient references in various services, improving code clarity.
