`157670e`, `77da99b`, `f9aa12c`, `05a6a42` +**Status**: ✅ Success + +#### What I Did +- Implemented comprehensive database connection package with pooling and transaction support +- Added PostgreSQL driver (lib/pq v1.10.9) and migration framework (golang-migrate v4.19.0) +- Created migration management system with automatic execution on server startup +- Integrated database initialization into main server with graceful lifecycle management +- Set up GitHub Actions CI/CD workflow with PostgreSQL and Redis service containers +- Added comprehensive database connectivity tests with environment-based configuration +- Updated environment variable documentation with SSL mode options + +#### Database Package Features (internal/database/) +**database.go**: +- Connection pooling with configurable max open/idle connections +- Health check functionality with timeout support +- Graceful shutdown handling +- Transaction wrapper pattern (design.md Section 8.6) +- Context-aware operations with cancellation support +- Comprehensive logging with zap +- Statistics monitoring via Stats() + +**migrate.go**: +- Automated migration execution with golang-migrate +- Migration version tracking and status checking +- Rollback support for development +- Safe error handling with ErrNoChange detection +- Migration to specific version support + +**database_test.go**: +- Comprehensive unit and integration tests +- Environment-based configuration for CI/CD +- Transaction rollback testing +- Health check verification +- Connection pooling validation +- Tests skip in short mode for quick local testing + +#### Server Integration (cmd/fgc-server/main.go) +- Database initialization with config and logger +- Automatic migration execution on startup +- Migration version logging for debugging +- Graceful shutdown with deferred Close() +- Proper error handling with Fatal logging +- Resolved TODO: Initialize database connection + +#### CI/CD Infrastructure (.github/workflows/test.yml) +**Service Containers**: +- PostgreSQL 14 with health checks (port 5432) +- Redis 7-alpine with health checks (port 6379) +- Automatic service readiness verification + +**Test Pipeline**: +- Unit tests with race detection (-race flag) +- Code coverage with atomic mode +- Coverage reporting and threshold enforcement +- go vet static analysis +- go fmt verification +- Integration test support (when directory exists) +- Binary build verification (fgc-server and fgc) +- Artifact upload for debugging (coverage + binaries) + +**Security Features**: +- All credentials from environment variables +- No hardcoded secrets in code or workflows +- SSL mode configurable (disable/prefer/require/verify-ca/verify-full) +- GitHub secrets integration ready +- Service container isolation per job + +#### Tests +- ✅ TestNew - Database connection creation and validation +- ✅ TestDB_Ping - Connection health checking +- ✅ TestDB_HealthCheck - Full health verification +- ✅ TestDB_Stats - Connection pool statistics +- ✅ TestDB_WithTransaction - Transaction commit and rollback +- ✅ TestDB_Close - Graceful connection closure +- ✅ Build verification - fgc-server binary compiles (15MB) +- ✅ All tests use environment variables (FGC_DATABASE_*) +- ✅ Integration tests skip in short mode + +#### Issues Encountered +**Network connectivity issue**: +- Go module proxy had DNS resolution failures in sandbox +- Solution: Used GOPROXY=direct to download from source +- All dependencies successfully downloaded and verified + +**SSL configuration**: +- Added FGC_DATABASE_SSL_MODE to .env.example (was missing) +- Default: "prefer" (tries SSL, falls back to non-SSL) +- Production recommendation: "require" or "verify-full" + +#### Files Changed +**New Files**: +- `internal/database/database.go` - Main database connection package +- `internal/database/migrate.go` - Migration management +- `internal/database/database_test.go` - Comprehensive test suite +- `.github/workflows/test.yml` - CI/CD pipeline + +**Modified Files**: +- `cmd/fgc-server/main.go` - Database initialization integration +- `go.mod` / `go.sum` - Added dependencies (lib/pq, golang-migrate, testify) +- `.env.example` - Added DATABASE_SSL_MODE documentation + +#### Configuration +All database configuration sourced from environment variables via existing config package: +- `FGC_DATABASE_HOST` - Database server hostname (default: localhost) +- `FGC_DATABASE_PORT` - Database server port (default: 5432) +- `FGC_DATABASE_NAME` - Database name (required) +- `FGC_DATABASE_USER` - Database username (required) +- `FGC_DATABASE_PASSWORD` - Database password (from secrets) +- `FGC_DATABASE_SSL_MODE` - SSL mode (default: prefer) +- `FGC_DATABASE_MAX_CONNECTIONS` - Max open connections (default: 25) +- `FGC_DATABASE_MAX_IDLE_CONNECTIONS` - Max idle connections (default: 5) +- `FGC_DATABASE_CONNECTION_MAX_LIFETIME` - Connection lifetime (default: 1h) + +#### Performance Characteristics +- Connection pool prevents connection exhaustion +- Idle connection reuse reduces latency +- Configurable pool size for load tuning +- Context timeouts prevent hanging operations +- Health checks every 10s in GitHub Actions +- Migration execution: <1s for schema creation + +#### References +- design.md Section 8 (Infrastructure Architecture) +- design.md Section 8.6 (Transaction Wrapper Pattern) +- design.md Section 10 (Testing Strategy) +- design.md Section 3.3 (Dependency Management) +- CLAUDE.md Testing Requirements +-
