# Phase 5 Implementation Summary
|
|
|
|
**Status**: ✅ COMPLETE
|
|
**Coverage**: 88.0%
|
|
**Date**: 2026-01-06
|

## What Was Implemented
|
|
|
|
### 1. Plugin System Core (10 phases)
|
|
- ✅ Plugin interface and registry (pre-existing, validated)
|
|
- ✅ 10 built-in DNS providers (Cloudflare, Route53, DigitalOcean, GCP, Azure, Namecheap, GoDaddy, Hetzner, Vultr, DNSimple)
|
|
- ✅ Secure plugin loader with SHA-256 verification
|
|
- ✅ Plugin database model and migrations
|
|
- ✅ Complete REST API for plugin management
|
|
- ✅ DNS provider service integration with registry
|
|
- ✅ Caddy config builder integration
|
|
- ✅ PowerDNS example plugin (compiles to 14MB .so)
|
|
- ✅ Comprehensive unit tests (88.0% coverage)
|
|
- ✅ Main.go and routes integration
|
|

### 3. Files Modified
|
|
```
|
|
backend/internal/services/dns_provider_service.go
|
|
- Removed hardcoded provider lists
|
|
- Added GetSupportedProviderTypes()
|
|
- Added GetProviderCredentialFields()
|
|
|
|
backend/internal/caddy/config.go
|
|
- Uses provider.BuildCaddyConfig() from registry
|
|
- Propagation timeout from provider
|
|
|
|
backend/cmd/api/main.go
|
|
- Import builtin providers
|
|
- Initialize plugin loader
|
|
- AutoMigrate Plugin model
|
|
|
|
backend/internal/api/routes/routes.go
|
|
- Added plugin API routes
|
|
- AutoMigrate Plugin model
|
|
|
|
backend/internal/api/handlers/dns_provider_handler_test.go
|
|
- Added mock methods for new service interface
|
|

|
## Test Results
|
|
|
|
```
|
|
Coverage: 88.0% (Required: 85%+)
|
|
Status: ✅ PASS
|
|
All packages compile: ✅ YES
|
|
PowerDNS plugin builds: ✅ YES (14MB)
|
|
```
|
|
|
|
## API Endpoints
|
|
|
|
```
|
|
GET /admin/plugins - List all plugins
|
|
GET /admin/plugins/:id - Get plugin details
|
|
POST /admin/plugins/:id/enable - Enable plugin
|
|
POST /admin/plugins/:id/disable - Disable plugin
|
|
POST /admin/plugins/reload - Reload all plugins
|
|
```
|
|
|
|
## Build Commands
|
|
|
|
```bash
|
|
# Build backend
|
|
cd backend && go build -v ./...
|
|
|
|
# Build PowerDNS plugin
|
|
cd plugins/powerdns
|
|
CGO_ENABLED=1 go build -buildmode=plugin -o powerdns.so main.go
|
|
|
|
# Run tests with coverage
|
|
cd backend
|
|
go test -v -coverprofile=coverage.txt ./...
|
|
```
|
|
|
|
## Security Features
|
|
- ✅ SHA-256 signature verification
|
|
- ✅ Directory permission validation (rejects world-writable)
|
|
- ✅ Windows platform rejection (Go plugin limitation)
|
|
- ✅ Usage checking (prevents disabling in-use plugins)
|
|
|
|
## Known Limitations
|
|
- Linux/macOS only (Go plugin constraint)
|
|
- CGO required (`CGO_ENABLED=1`)
|
|
- Same Go version required for plugin and Charon
|
|
- No hot reload (requires application restart)
|
|
- ~14MB per plugin (Go runtime embedded)
|
|
|
|
## Next Steps
|
|
Frontend implementation (Phase 6) - Plugin management UI
