chore: add dockerfile, add rollup id to cmd options #27
Conversation
WalkthroughThis pull request introduces a Dockerfile for a Go application named "centralized-sequencer," implementing a multi-stage build process. The first stage sets up the Go environment and compiles the application, while the second stage prepares the runtime environment. Additionally, it adds a new command-line flag Changes

71-71: Improve server startup log message.The current log message hardcodes the port number even though it's configurable. It should also include more relevant information.
Consider updating the log message:
- log.Println("Starting centralized sequencing gRPC server on port 50051...") + log.Printf("Starting centralized sequencing gRPC server on %s (rollup ID: %s)...", address, rollupId)
Line range hint
26-47: Consider enhancing the configuration and lifecycle management.The current implementation could benefit from several architectural improvements:
- Support environment variables for configuration to align with container best practices
- Implement proper graceful shutdown for the gRPC server
- Add comprehensive configuration validation
Consider these enhancements:
- Use a configuration package that supports both flags and environment variables (e.g.,
viper)- Implement graceful shutdown:
stop := make(chan os.Signal, 1) signal.Notify(stop, os.Interrupt, syscall.SIGTERM) go func() { if err := grpcServer.Serve(lis); err != nil { log.Fatalf("Failed to serve: %v", err) } }() <-stop log.Println("Shutting down server...") grpcServer.GracefulStop()
- Add a
validateConfig()function to check all settings before server startupsequencing/sequencer_test.go (2)
54-54: Enhance test coverage for rollup ID initialization.While the test verifies basic sequencer creation, consider adding test cases to validate:
- Initialization with empty rollup ID
- Initialization with invalid rollup ID format
- Verification that the initialized sequencer has the correct rollup ID value
Example test cases to add:
// Test with empty rollup ID _, err = NewSequencer(MockDAAddressHTTP, "authToken", []byte("namespace"), []byte{}, 1*time.Second, "") assert.Error(t, err) // Verify rollup ID is correctly set seq, err := NewSequencer(MockDAAddressHTTP, "authToken", []byte("namespace"), []byte("rollup1"), 1*time.Second, "") require.NoError(t, err) assert.Equal(t, []byte("rollup1"), seq.rollupId)
Line range hint
1-199: Consider enhancing test documentation.While the test implementation is solid, consider adding:
- A package-level comment describing the test coverage strategy
- Comments explaining the purpose of test constants and helper functions
- Documentation for the mock DA server setup and its purpose
Example package comment:
/* Package sequencing_test provides comprehensive test coverage for the sequencing package. It includes tests for sequencer initialization, transaction submission, batch handling, and rollup ID validation. The tests use a mock DA server for isolation and reliability. */ package sequencingsequencing/sequencer.go (3)
Line range hint
287-316: Add validation for the rollupId parameter.The
rollupIdparameter should be validated to ensure it's neither nil nor empty, as these cases could cause issues during transaction validation.Consider adding this validation at the beginning of the constructor:
func NewSequencer(daAddress, daAuthToken string, daNamespace []byte, rollupId []byte, batchTime time.Duration, dbPath string) (*Sequencer, error) { + if len(rollupId) == 0 { + return nil, fmt.Errorf("rollupId cannot be empty") + } ctx := context.Background()
Line range hint
600-602: Improve method documentation and naming.The
isValidmethod would benefit from:
- A descriptive name that indicates what it validates
- Documentation explaining its purpose and parameters
Consider this improvement:
-func (c *Sequencer) isValid(rollupId []byte) bool { +// validateRollupId checks if the provided rollupId matches the sequencer's configured rollupId. +// This ensures that transactions and batches are processed for the correct rollup chain. +func (c *Sequencer) validateRollupId(rollupId []byte) bool { return bytes.Equal(c.rollupId, rollupId) }
Line range hint
287-602: Consider architectural improvements for rollup ID validation.The rollup ID validation is a critical security feature. Consider these improvements:
- Add detailed error messages including the expected and received rollup IDs
- Add logging for validation failures to aid in monitoring and debugging
- Consider using a custom type for rollup IDs to enforce validation at compile time
Example implementation:
// RollupID is a type-safe wrapper for rollup identifiers type RollupID []byte // NewRollupID creates a new RollupID with validation func NewRollupID(id []byte) (RollupID, error) { if len(id) == 0 { return nil, fmt.Errorf("rollup ID cannot be empty") } return RollupID(id), nil } // Equals safely compares two rollup IDs func (r RollupID) Equals(other []byte) bool { return bytes.Equal(r, other) }

7-16: LGTM! Follows Docker best practices
The build stage setup is well-structured:
- Separates dependency download from source code copy for optimal layer caching
- Uses appropriate working directory

65-68: Verify rollup ID handling in the sequencer package.
The rollup ID is passed directly to the sequencer without any preprocessing or validation. We should verify how the sequencer handles this value.
Let's check the sequencer implementation:
✅ Verification successful
Let me gather more information about how the rollupId is used in the sequencer implementation.
Based on the gathered information, I can now generate the final response:
Rollup ID handling in the sequencer is properly implemented
The sequencer implementation shows appropriate handling of the rollup ID:
- It's stored as a field in the Sequencer struct and used for validation
- The
isValidmethod performs proper validation using securebytes.Equalcomparison - Test cases cover both valid and invalid rollup ID scenarios
- The implementation includes proper error handling for mismatched rollup IDs

70-70: LGTM! Good error handling coverage.
The test thoroughly covers both successful transaction submission and rollup ID validation, including:
- Successful case with matching rollup ID
- Error case with mismatched rollup ID
- Proper cleanup with deferred close
