# Audit and Testing Guide
|
||||
|
||||
Comprehensive guide for testing and auditing the MEV bot codebase.
|
||||
|
||||
## Quick Reference
|
||||
|
||||
```bash
|
||||
# Run everything
|
||||
./scripts/dev.sh test all # All tests
|
||||
./scripts/dev.sh audit # Code quality audit
|
||||
./scripts/dev.sh check-compliance # SPEC.md compliance
|
||||
./scripts/dev.sh check-docs # Documentation coverage
|
||||
|
||||
# Specific tests
|
||||
./scripts/dev.sh test unit # Unit tests only
|
||||
./scripts/dev.sh test coverage # Coverage report
|
||||
./scripts/dev.sh test race # Race detection
|
||||
./scripts/dev.sh test bench # Benchmarks
|
||||
```
|
||||
|
||||
## Testing Suite
|
||||
|
||||
### 1. Unit Tests
|
||||
|
||||
Fast tests that verify individual components in isolation.
|
||||
|
||||
```bash
|
||||
# Run all unit tests
|
||||
./scripts/dev.sh test unit
|
||||
|
||||
# Run tests for specific package
|
||||
./scripts/dev.sh test pkg sequencer
|
||||
|
||||
# Verbose output
|
||||
./scripts/test.sh unit true
|
||||
```
|
||||
|
||||
**What it tests:**
|
||||
- Individual function correctness
|
||||
- Edge cases and error handling
|
||||
- Component behavior in isolation
|
||||
|
||||
**Files:** All `*_test.go` files in `pkg/`
|
||||
|
||||
### 2. Integration Tests
|
||||
|
||||
Tests that verify components work together correctly.
|
||||
|
||||
```bash
|
||||
# Run integration tests
|
||||
./scripts/dev.sh test integration
|
||||
```
|
||||
|
||||
**What it tests:**
|
||||
- Sequencer → Swap Filter → Pool Cache pipeline
|
||||
- Database operations
|
||||
- External service interactions
|
||||
|
||||
**Files:** `tests/*_integration_test.go`
|
||||
|
||||
### 3. Race Detection
|
||||
|
||||
Detects data races in concurrent code.
|
||||
|
||||
```bash
|
||||
# Run with race detector
|
||||
./scripts/dev.sh test race
|
||||
```
|
||||
|
||||
**What it checks:**
|
||||
- Concurrent access to shared state
|
||||
- Mutex usage correctness
|
||||
- Channel safety
|
||||
|
||||
**Important:** Always run before committing concurrent code changes.
|
||||
|
||||
### 4. Benchmarks
|
||||
|
||||
Performance testing for critical paths.
|
||||
|
||||
```bash
|
||||
# Run benchmarks
|
||||
./scripts/dev.sh test bench
|
||||
```
|
||||
|
||||
**What it measures:**
|
||||
- Swap parsing throughput
|
||||
- Pool cache lookup speed
|
||||
- Channel message processing rate
|
||||
|
||||
**Files:** Functions named `Benchmark*` in `*_test.go`
|
||||
|
||||
### 5. Coverage Report
|
||||
|
||||
Measures test coverage percentage.
|
||||
|
||||
```bash
|
||||
# Generate coverage report
|
||||
./scripts/dev.sh test coverage
|
||||
```
|
||||
|
||||
**Output:**
|
||||
- `coverage/coverage.out` - Coverage data
|
||||
- `coverage/coverage.html` - HTML report (open in browser)
|
||||
|
||||
**Target:** >70% coverage for production code
|
||||
|
||||
## Audit Suite
|
||||
|
||||
### 1. Codebase Audit
|
||||
|
||||
Comprehensive code quality and security check.
|
||||
|
||||
```bash
|
||||
./scripts/dev.sh audit
|
||||
```
|
||||
|
||||
**Checks:**
|
||||
|
||||
#### Code Quality
|
||||
- `go vet` warnings
|
||||
- TODO/FIXME comments
|
||||
- panic() usage
|
||||
- Error handling patterns
|
||||
|
||||
#### Security
|
||||
- Hardcoded secrets
|
||||
- SQL injection risks
|
||||

||||
- Unsafe pointer usage
|
||||
|
||||
#### Concurrency
|
||||
- Race condition risks
|
||||
- Mutex coverage
|
||||
- Channel usage
|
||||
|
||||
#### SPEC.md Compliance

||||
- Manual ABI files (forbidden)
|
||||
|
||||
**Exit codes:**
|
||||

|
||||
- 1: Issues found (review required)
|
||||
|
||||
### 2. Documentation Coverage
|
||||
|
||||
Verifies all code is properly documented.
|
||||
|
||||
```bash

|
||||
**Checks:**
|
||||
|
||||
- Package `doc.go` files
|
||||
- Exported function comments
|
||||
- Exported type comments
|
||||
- README files in key directories
|
||||
- Project documentation (SPEC.md, CLAUDE.md, etc.)
|
||||
- Inline comment density
|
||||
|
||||
**Target:** >80% documentation coverage
|
||||
|
||||
### 3. SPEC.md Compliance
|
||||
|
||||
Ensures code adheres to all SPEC.md requirements.
|
||||
|
||||
```bash
|
||||
./scripts/dev.sh check-compliance
|
||||

|
||||
|
||||
## Continuous Integration
|
||||
|
||||
### Pre-Commit Checks
|
||||
|
||||
Run before every commit:
|
||||
|
||||
```bash
|
||||
# Quick validation
|
||||
./scripts/dev.sh test unit
|
||||
./scripts/dev.sh check-compliance
|
||||
|
||||
# Full pre-commit
|
||||
./scripts/dev.sh test all
|
||||
./scripts/dev.sh audit
|
||||
```
|
||||
|
||||
### Pre-Push Checks
|
||||
|
||||
Run before pushing to remote:
|
||||
|
||||
```bash
|
||||
# Comprehensive check
|
||||
./scripts/dev.sh test all
|
||||
./scripts/dev.sh test race
|
||||
./scripts/dev.sh audit
|
||||
./scripts/dev.sh check-compliance
|
||||
./scripts/dev.sh check-docs
|
||||
```
|
||||
|
||||
### Pre-Release Checks
|
||||
|
||||
Run before creating a release:
|
||||
|
||||
```bash
|
||||
# Full audit
|
||||
./scripts/dev.sh test coverage # Ensure >70%
|
||||
./scripts/dev.sh test bench # Check performance
|
||||
./scripts/dev.sh audit # Security & quality
|
||||
./scripts/dev.sh check-compliance # SPEC.md adherence
|
||||
./scripts/dev.sh check-docs # Documentation complete
|
||||
```
|
||||
|
||||
## Test Writing Guidelines
|
||||
|
||||
### Unit Test Example
|
||||
|
||||
```go
|
||||
// pkg/sequencer/swap_filter_test.go
|
||||
func TestSwapFilter_DetectUniswapV2Swap(t *testing.T) {
|
||||
// Setup
|
||||
filter := NewSwapFilter(logger, poolCache)
|
||||
|
||||
// Create test message with known swap
|
||||
msg := map[string]interface{}{
|
||||
"messages": []interface{}{
|
||||
map[string]interface{}{
|
||||
"message": map[string]interface{}{
|
||||
"l2Msg": base64EncodedSwapTx,
|
||||
},
|
||||
},
|
||||
},
|
||||
}
|
||||
|
||||
// Execute
|
||||
filter.ProcessMessage(msg)
|
||||
|
||||
// Verify
|
||||
select {
|
||||
case swap := <-filter.SwapCh():
|
||||
assert.Equal(t, "UniswapV2", swap.Protocol.Name)
|
||||
assert.NotEqual(t, common.Address{}, swap.Pool.Address)
|
||||
case <-time.After(time.Second):
|
||||
t.Fatal("timeout waiting for swap event")
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Benchmark Example
|
||||
|
||||
```go
|
||||
// pkg/pools/cache_bench_test.go
|
||||
func BenchmarkPoolCache_Lookup(b *testing.B) {
|
||||
cache := NewPoolCache(...)
|
||||
|
||||
// Pre-populate cache
|
||||
for i := 0; i < 1000; i++ {
|
||||
cache.AddOrUpdate(generateTestPool())
|
||||
}
|
||||
|
||||
addr := testPoolAddress
|
||||
|
||||
b.ResetTimer()
|
||||
for i := 0; i < b.N; i++ {
|
||||
cache.Get(addr)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Integration Test Example
|
||||
|
||||
```go
|
||||
// tests/sequencer_integration_test.go
|
||||
func TestSequencerToPoolCache_Pipeline(t *testing.T) {
|
||||
// Start real sequencer feed
|
||||
reader := sequencer.NewReader(config)
|
||||
swapFilter := sequencer.NewSwapFilter(logger, poolCache)
|
||||
|
||||
// Connect pipeline
|
||||
go reader.Start(ctx)
|
||||
go swapFilter.Start(ctx)
|
||||
|
||||
// Wait for real swaps from mainnet
|
||||
timeout := time.After(30 * time.Second)
|
||||
swapsFound := 0
|
||||
|
||||
for swapsFound < 5 {
|
||||
select {
|
||||
case swap := <-swapFilter.SwapCh():
|
||||
// Verify swap is valid
|
||||
assert.NotEqual(t, common.Address{}, swap.Pool.Address)
|
||||
swapsFound++
|
||||
case <-timeout:
|
||||
t.Fatalf("only found %d swaps in 30s", swapsFound)
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Common Issues
|
||||
|
||||
### Issue: Tests timeout
|
||||
|
||||
**Cause:** Blocking operations in tests
|
||||
|
||||
**Fix:**
|
||||
```go
|
||||
// Bad
|
||||
time.Sleep(10 * time.Second)
|
||||
|
||||
// Good
|
||||
select {
|
||||
case result := <-resultCh:
|
||||
// ...
|
||||
case <-time.After(5 * time.Second):
|
||||
t.Fatal("timeout")
|
||||
}
|
||||
```
|
||||
|
||||
### Issue: Race detector reports races
|
||||
|
||||
**Cause:** Unprotected shared state
|
||||
|
||||
**Fix:**
|
||||
```go
|
||||
// Bad
|
||||
var counter int
|
||||
func increment() { counter++ }
|
||||
|
||||
// Good
|
||||
var mu sync.Mutex
|
||||
var counter int
|
||||
func increment() {
|
||||
mu.Lock()
|
||||
defer mu.Unlock()
|
||||
counter++
|
||||
}
|
||||
```
|
||||
|
||||
### Issue: Low coverage
|
||||
|
||||
**Cause:** Missing test cases
|
||||
|
||||
**Fix:**
|
||||
1. Identify uncovered code: `go tool cover -func=coverage/coverage.out`
|
||||
2. Add tests for edge cases
|
||||
3. Test error paths
|
||||
4. Add table-driven tests
|
||||
|
||||
## Metrics and Monitoring
|
||||
|
||||
### Coverage Trends
|
||||
|
||||
Track coverage over time:
|
||||
|
||||
```bash
|
||||
# Generate report
|
||||
./scripts/dev.sh test coverage
|
||||
|
||||
# View current coverage
|
||||
grep "total:" coverage/coverage.out
|
||||
```
|
||||
|
||||
### Performance Baselines
|
||||
|
||||
Establish performance baselines:
|
||||
|
||||
```bash
|
||||
# Run benchmarks
|
||||
./scripts/dev.sh test bench > benchmarks/baseline-$(date +%Y%m%d).txt
|
||||
|
||||
# Compare with previous
|
||||
benchstat benchmarks/baseline-old.txt benchmarks/baseline-new.txt
|
||||
```
|
||||
|
||||
## CI/CD Integration
|
||||
|
||||
### GitHub Actions Example
|
||||
|
||||
```yaml
|
||||
name: Test Suite
|
||||
|
||||
on: [push, pull_request]
|
||||
|
||||
jobs:
|
||||
test:
|
||||
runs-on: ubuntu-latest
|
||||
steps:
|
||||
- uses: actions/checkout@v3
|
||||
|
||||
- name: Start dev environment
|
||||
run: ./scripts/dev.sh up
|
||||

# Development Environment Setup
|
||||
|
||||
## Overview
|
||||
|
||||
This project enforces **containerized development** for consistency and adherence to SPEC.md requirements.
|
||||
|
||||
## Key Documents
|
||||
|
||||
- **SPEC.md** - Technical specification and architecture requirements
|
||||
- **CLAUDE.md** - Development guidelines and workflow
|
||||
- **bindings/README.md** - Contract bindings usage and generation
|
||||
|
||||
## Quick Start
|
||||
|
||||
```bash
|
||||
# 1. Start development containers
|
||||
./scripts/dev.sh up
|
||||
|
||||
# 2. Build contracts
|
||||
./scripts/dev.sh forge-build
|
||||
|
||||
# 3. Generate Go bindings
|
||||
./scripts/dev.sh bindings
|
||||
|
||||
# 4. Build Go application
|
||||
./scripts/dev.sh build
|
||||
|
||||
# 5. Run tests
|
||||
./scripts/dev.sh test
|
||||
```
|
||||
|
||||
## Development Workflow
|
||||
|
||||
### 1. Container-Based Development
|
||||
|
||||
**NEVER run builds or tests outside of containers.**
|
||||
|
||||
All commands use `./scripts/dev.sh` which ensures:
|
||||
- Consistent build environment
|
||||
- Proper dependency management
|
||||
- Compliance with SPEC.md
|
||||
- Reproducible builds
|
||||
|
||||
### 2. Contract Development
|
||||
|
||||
```bash
|
||||
# Build all Solidity contracts
|
||||
./scripts/dev.sh forge-build
|
||||
|
||||
# Run contract tests
|
||||
./scripts/dev.sh forge-test
|
||||
|
||||
# Generate Go bindings from ABIs
|
||||
./scripts/dev.sh bindings
|
||||
```
|
||||
|
||||
**Contract Structure:**
|
||||

|
||||
└── foundry.toml # Foundry configuration
|
||||
```
|
||||
|
||||
### 3. Go Development
|
||||
|
||||
```bash
|
||||
# Build application
|
||||
./scripts/dev.sh build
|
||||
|
||||
# Run tests
|
||||
./scripts/dev.sh test
|
||||
|
||||
# Enter Go container for interactive development
|
||||
./scripts/dev.sh go
|
||||
# Inside container:
|
||||
# go test ./pkg/sequencer/... -v
|
||||
# go run ./cmd/mev-bot/main.go
|
||||
```
|
||||
|
||||
### 4. Binding Generation
|
||||
|
||||
**IMPORTANT**: Use official contract ABIs from Foundry builds, NOT manual JSON files.
|
||||
|
||||
```bash
|
||||
# 1. Build contracts first
|
||||
./scripts/dev.sh forge-build
|
||||
|
||||
# 2. Generate bindings
|
||||
./scripts/dev.sh bindings
|
||||
|
||||
# Generated bindings appear in:
|
||||
bindings/
|
||||
├── uniswap_v2/
|
||||
│ ├── router.go # UniswapV2Router02
|
||||
│ └── pair.go # UniswapV2Pair
|
||||
├── uniswap_v3/
|
||||
│ ├── router.go # SwapRouter

## Common Tasks
|
||||
|
||||
### Adding New DEX Contract
|
||||
|
||||
```bash
|
||||
# 1. Enter Foundry container
|
||||
./scripts/dev.sh foundry
|
||||
|
||||
# 2. Install official contract
|
||||
cd /workspace/contracts
|
||||
forge install <org>/<repo>
|
||||
|
||||
# 3. Exit container and rebuild
|
||||
exit
|
||||
./scripts/dev.sh forge-build
|
||||
|
||||
# 4. Generate Go bindings
|
||||
./scripts/dev.sh bindings
|
||||
```
|
||||
|
||||
### Debugging Build Issues
|
||||
|
||||
```bash
|
||||
# Check container status
|
||||
./scripts/dev.sh ps
|
||||
|
||||
# View logs
|
||||
./scripts/dev.sh logs go-dev
|
||||
|
||||
# Clean and rebuild
|
||||
./scripts/dev.sh clean
|
||||
./scripts/dev.sh forge-build
|
||||
./scripts/dev.sh build
|
||||
```
|
||||
|
||||
### Running Specific Tests
|
||||
|
||||
```bash
|
||||
# Enter Go container
|
||||
./scripts/dev.sh go
|
||||
|
||||
# Inside container, run specific tests
|
||||
go test ./pkg/sequencer/... -v -run TestSwapFilter
|
||||
go test ./pkg/pools/... -v -run TestPoolCache
|
||||
```
|
||||
|
||||
## Development Rules (from SPEC.md)
|
||||
|
||||
### MUST DO ✅
|
||||
- Use `./scripts/dev.sh` for all operations
|
||||
- Use Arbitrum sequencer feed as primary data source
|
||||
- Derive contract ABIs from official sources via Foundry
|
||||
- Generate Go bindings with `abigen`
|
||||
- Use channels for ALL inter-component communication
|
||||
- Validate ALL parsed data before propagation
|
||||
- Emit comprehensive metrics and structured logs
|
||||
|
||||
### MUST NOT DO ❌
|
||||
- Run builds outside of containers
|
||||
- Use HTTP RPC as primary data source
|
||||
- Write manual ABI JSON files
|
||||
- Hardcode function selectors
|
||||
- Allow zero addresses or zero amounts to propagate
|
||||
- Use blocking operations in hot paths
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Container Won't Start
|
||||
|
||||
```bash
|
||||
# Check Podman status
|
||||
podman ps -a
|
||||
|
||||
# Check logs
|
||||
podman logs mev-go-dev
|
||||
|
||||
# Force restart
|
||||
./scripts/dev.sh down
|
||||
./scripts/dev.sh up
|
||||
```
|
||||
|
||||
### Build Failures
|
||||
|
||||
```bash
|
||||
# Clean artifacts
|
||||
./scripts/dev.sh clean
|
||||
|
||||
# Restart containers
|
||||
./scripts/dev.sh restart
|
||||
|
||||
# Rebuild
|
||||
./scripts/dev.sh forge-build
|
||||
./scripts/dev.sh build
|
||||
```
|
||||
|
||||
### Binding Generation Fails
|
||||
|
||||
```bash
|
||||
# Ensure contracts are built first
|
||||
./scripts/dev.sh forge-build
|
||||
|
||||
# Check for artifacts
|
||||
ls -la contracts/out/
|
||||
|
||||
# Manually generate if needed
|
||||
./scripts/dev.sh go
|
||||
# Inside container:
|
||||
./scripts/generate-bindings-in-container.sh
|
||||
```
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Add More DEX Contracts**: Install Camelot, Balancer, Curve, Kyber
|
||||
2. **Fix Contract Compilation**: Resolve Solidity errors in src/
|
||||
3. **Complete Swap Detection**: Implement ABI-based swap parsing
|
||||
4. **Test Pool Discovery**: Verify pool cache functionality
|
||||
5. **Deploy Phase 1**: Monitor sequencer feed in production

# Codebase Refactoring Plan
|
||||
|
||||
## Overview
|
||||
|
||||
This document outlines the systematic refactoring of the MEV bot codebase to ensure:
|
||||
- SPEC.md compliance
|
||||
- Code consistency
|
||||
- Thread safety
|
||||
- Proper error handling
|
||||
- Channel-based architecture
|
||||
|
||||
## Critical Issues Identified
|
||||
|
||||
### 🔴 CRITICAL (Must fix immediately)
|
||||
|
||||
1. **Hardcoded Function Selectors** (decoder.go, discovery.go)
|
||||
- Violates SPEC.md requirement for ABI-based detection
|
||||
- 12+ hardcoded selectors found
|
||||
- **Fix:** Use generated bindings with `abi.MethodById()`
|
||||
|
||||
2. **Silent Error Handling** (swap_filter.go)
|
||||
- Errors ignored without logging
|
||||
- Violates "fail-fast" philosophy
|
||||
- **Fix:** Log all errors with context
|
||||
|
||||
3. **Race Conditions on Metrics** (reader.go)
|
||||
- Unprotected metric counters
|
||||
- Data race potential
|
||||
- **Fix:** Use `atomic` or mutex protection
|
||||
|
||||
4. **Blocking RPC Calls in Hot Path** (reader.go)
|
||||
- RPC call in message processing worker
|
||||
- Defeats purpose of sequencer feed
|
||||
- **Fix:** Extract full TX data from sequencer message
|
||||
|
||||
5. **Non-Channel Communication** (swap_filter.go)
|
||||
- Direct function calls instead of channels
|
||||
- Violates SPEC.md architecture
|
||||
- **Fix:** Input channel for messages
|
||||
|
||||
### 🟡 HIGH PRIORITY (Fix before next release)
|
||||
|
||||
6. **Zero Address Validation Missing** (all files)
|
||||
- No validation of addresses
|
||||
- Can propagate invalid data
|
||||
- **Fix:** Validate all addresses on input
|
||||
|
||||
7. **Hardcoded DEX Addresses** (decoder.go, discovery.go)
|
||||
- 12 router addresses hardcoded
|
||||
- Not configurable
|
||||
- **Fix:** Move to configuration file
|
||||
|
||||
8. **Logger Inconsistency** (reader.go, cache.go)
|
||||
- Mixed logging libraries (slog vs go-ethereum/log)
|
||||
- Hacky adapter pattern
|
||||
- **Fix:** Standardize on go-ethereum/log
|
||||
|
||||
9. **Manual Metrics Counters** (reader.go, discovery.go)
|
||||
- Not using Prometheus
|
||||
- No standard metrics export
|
||||
- **Fix:** Implement Prometheus metrics
|
||||
|
||||
10. **Potential Deadlock** (cache.go)
|
||||
- Lock held during goroutine spawn
|
||||
- Save() called with lock
|
||||
- **Fix:** Proper lock ordering
|
||||
|
||||
### 🟢 MEDIUM PRIORITY (Improve maintainability)
|
||||
|
||||
11. **Emojis in Production Logs** (cache.go)
|
||||
- Unprofessional, hard to parse
|
||||
- **Fix:** Remove emojis, use structured fields
|
||||
|
||||
12. **Unused Config Fields** (discovery.go)
|
||||
- ConcurrentFetches, StartBlock unused
|
||||
- **Fix:** Implement or remove
|
||||
|
||||
13. **Magic Numbers** (reader.go)
|
||||
- 50ms timeout hardcoded
|
||||
- **Fix:** Make configurable
|
||||
|
||||
14. **Inconsistent Error Levels** (all files)
|
||||
- Parse errors at Debug level
|
||||
- **Fix:** Standardize error levels
|
||||
|
||||
15. **Untracked Goroutines** (cache.go)
|
||||
- Background save goroutine not in WaitGroup
|
||||
- **Fix:** Proper lifecycle management
|
||||
|
||||
## Refactoring Strategy
|
||||
|
||||
### Phase 1: Critical Fixes (COMPLETED - 2025-11-11)
|
||||
|
||||
**Priority:** SPEC.md compliance and correctness
|
||||
|
||||
1. ✅ Create validation package - `pkg/validation/helpers.go`
|
||||
2. ✅ Add atomic metrics - Fixed race conditions in `reader.go` and `swap_filter.go`
|
||||
3. ✅ Fix error handling - Added logging to silent failures
|
||||
4. ✅ Add address validation - Validates zero addresses at ingress points
|
||||
5. ✅ Create selector registry - `pkg/sequencer/selector_registry.go` (prep for ABI)
|
||||
|
||||
### Phase 2: Architecture Improvements (Next)
|
||||
|
||||
1. Implement channel-based swap filter
|
||||
2. Add Prometheus metrics
|
||||
3. Standardize logging
|
||||
4. Move configs out of code
|
||||
|
||||
### Phase 3: Code Quality (Future)
|
||||
|
||||
1. Remove emojis
|
||||
2. Implement unused features
|
||||
3. Add comprehensive tests
|
||||
4. Performance optimization
|
||||
|
||||
## Detailed Refactoring Tasks

|
||||
**Example:**
|
||||
```go
|
||||
func ValidateAddress(addr common.Address) error {
|
||||
if addr == (common.Address{}) {
|
||||
return errors.New("zero address")
|
||||
}

||||
|
||||
func (r *Reader) incrementTxReceived() {
|
||||
r.txReceived++ // RACE!
|
||||
}
|
||||
```
|
||||
|
||||
**After:**
|
||||
```go
|
||||
type Reader struct {
|
||||
txReceived atomic.Uint64
|
||||
// ...
|
||||
}
|
||||
|
||||
func (r *Reader) incrementTxReceived() {

|
||||
// Not all messages are valid, skip silently
|
||||
return
|
||||
}
|
||||
```
|
||||
|
||||
**After:**
|
||||
```go

|
||||
|
||||
## Testing Strategy
|
||||
|
||||
For each refactoring task:
|
||||
|
||||
1. **Before Refactoring:**
|
||||
- Run `./scripts/dev.sh test unit` - Baseline
|
||||
- Run `./scripts/dev.sh audit` - Document issues
|
||||
|
||||
2. **During Refactoring:**
|
||||
- Make changes incrementally
|
||||
- Compile after each change
|
||||
- Run relevant package tests
|
||||
|
||||
3. **After Refactoring:**
|
||||
- Run `./scripts/dev.sh test all`
|
||||
- Run `./scripts/dev.sh test race` - Check for new races
|
||||
- Run `./scripts/dev.sh check-compliance` - Verify SPEC compliance
|
||||
- Run `./scripts/dev.sh audit` - Verify improvements
|
||||
|
||||
## Refactoring Progress
|
||||
|
||||
### Phase 1 (COMPLETED - 2025-11-11)
|
||||
|
||||
**Files Created:**
|
||||
- `pkg/validation/helpers.go` - Standalone validation functions for addresses/amounts
|
||||
- `pkg/sequencer/selector_registry.go` - Registry pattern for function selectors
|
||||
|
||||
**Files Modified:**
|
||||
- `pkg/sequencer/reader.go` - Converted metrics to atomic operations
|
||||
- `pkg/sequencer/swap_filter.go` - Fixed race conditions, added error logging
|
||||
- `pkg/sequencer/decoder.go` - Added address validation
|
||||
|
||||
**Changes Summary:**
|
||||
1. ✅ **Validation Package** - Added `ValidateAddress()`, `ValidateAmount()`, helper functions
|
||||
2. ✅ **Atomic Metrics** - Converted all `uint64` counters to `atomic.Uint64` in reader.go (9 metrics)
|
||||
3. ✅ **Atomic Metrics** - Converted metrics in swap_filter.go (4 metrics)
|
||||
4. ✅ **Error Logging** - Added debug logging for decode failures with metric tracking
|
||||
5. ✅ **Address Validation** - Validates addresses in `GetSwapProtocol()` and `discoverPool()`
|
||||
6. ✅ **Selector Registry** - Created thread-safe registry with ABI integration support
|
||||
|
||||
**Build Status:** ✅ All packages compile successfully
|
||||
|
||||

## Environment Variables
|
||||
|
||||
Scripts respect these environment variables:
|
||||
|
||||
```bash
|
||||
# Override container names
|
||||
GO_CONTAINER=mev-go-dev
|
||||
FOUNDRY_CONTAINER=mev-foundry
|
||||
PYTHON_CONTAINER=mev-python-dev
|
||||
|
||||
# Test verbosity
|
||||
TEST_VERBOSE=true
|
||||
|
||||
# Coverage threshold
|
||||
COVERAGE_THRESHOLD=70
|
||||
```
|
||||
|
||||
## Exit Codes
|
||||
|
||||
All scripts use consistent exit codes:
|
||||
|
||||
- **0:** Success (all checks passed)
|
||||
- **1:** Failure (tests failed, violations found, etc.)
|
||||
- **127:** Command not found
|
||||
- **255:** Container error
|
||||
|
||||
## Logging
|
||||
|
||||
Scripts use consistent logging format:
|
||||
|
||||
- `ℹ` - Info message (blue)
|
||||
- `✓` - Success (green)
|
||||
- `⚠` - Warning (yellow)
|
||||
- `✗` - Error (red)
