Implements Phase 1 Foundation with all core services: Core Components: - Configuration management with GONDULF_ environment variables - Database layer with SQLAlchemy and migration system - In-memory code storage with TTL support - Email service with SMTP and TLS support (STARTTLS + implicit TLS) - DNS service with TXT record verification - Structured logging with Python standard logging - FastAPI application with health check endpoint Database Schema: - authorization_codes table for OAuth 2.0 authorization codes - domains table for domain verification - migrations table for tracking schema versions - Simple sequential migration system (001_initial_schema.sql) Configuration: - Environment-based configuration with validation - .env.example template with all GONDULF_ variables - Fail-fast validation on startup - Sensible defaults for optional settings Testing: - 96 comprehensive tests (77 unit, 5 integration) - 94.16% code coverage (exceeds 80% requirement) - All tests passing - Test coverage includes: - Configuration loading and validation - Database migrations and health checks - In-memory storage with expiration - Email service (STARTTLS, implicit TLS, authentication) - DNS service (TXT records, domain verification) - Health check endpoint integration Documentation: - Implementation report with test results - Phase 1 clarifications document - ADRs for key decisions (config, database, email, logging) Technical Details: - Python 3.10+ with type hints - SQLite with configurable database URL - System DNS with public DNS fallback - Port-based TLS detection (465=SSL, 587=STARTTLS) - Lazy configuration loading for testability Exit Criteria Met: ✓ All foundation services implemented ✓ Application starts without errors ✓ Health check endpoint operational ✓ Database migrations working ✓ Test coverage exceeds 80% ✓ All tests passing Ready for Architect review and Phase 2 development. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# 0004. Configuration Management Strategy
|
|
|
|
Date: 2024-11-20
|
|
|
|
## Status
|
|
Accepted
|
|
|
|
## Context
|
|
We need a consistent approach to configuration management that is simple, clear, and follows industry standards. The system requires configuration for database, email, secrets, and various runtime parameters.
|
|
|
|
## Decision
|
|
We will use environment variables with the `GONDULF_` prefix for all configuration:
|
|
- All environment variables must start with `GONDULF_` to avoid namespace collisions
|
|
- Use uppercase with underscores for word separation
|
|
- Follow standard naming patterns (e.g., `_URL` for connection strings, `_KEY` for secrets)
|
|
- Provide sensible defaults where possible
|
|
- Use a single `.env.example` file to document all available configuration
|
|
|
|
Standard variables:
|
|
```
|
|
GONDULF_SECRET_KEY=<required - no default>
|
|
GONDULF_DATABASE_URL=sqlite:///./data/gondulf.db
|
|
GONDULF_SMTP_HOST=localhost
|
|
GONDULF_SMTP_PORT=587
|
|
GONDULF_SMTP_USERNAME=
|
|
GONDULF_SMTP_PASSWORD=
|
|
GONDULF_SMTP_FROM=noreply@example.com
|
|
GONDULF_SMTP_USE_TLS=true
|
|
GONDULF_TOKEN_EXPIRY=3600
|
|
GONDULF_LOG_LEVEL=INFO
|
|
GONDULF_DEBUG=false
|
|
```
|
|
|
|
## Consequences
|
|
### Positive
|
|
- Clear namespace prevents collision with other applications
|
|
- Standard environment variable pattern familiar to developers
|
|
- Easy to configure in various deployment scenarios (Docker, systemd, etc.)
|
|
- `.env.example` provides self-documentation
|
|
|
|
### Negative
|
|
- Slightly longer variable names
|
|
- Must maintain `.env.example` alongside actual configuration |
