+# Mattermost XMPP Bridge Plugin Architecture
+
+## Overview
+
+The Mattermost XMPP Bridge Plugin provides bidirectional message synchronization between Mattermost and XMPP servers through a comprehensive bridge architecture. The plugin is designed with extensibility in mind, supporting multiple bridge types and protocols through a unified interface.
+
+## Core Design Principles
+
+- **Bridge-Agnostic Architecture**: Extensible design supporting future bridges (Slack, Discord, etc.)
+- **Bidirectional Communication**: Real-time message synchronization in both directions
+- **Message Bus Pattern**: Centralized routing system for decoupled communication
+- **Thread-Safe Operations**: Goroutine-safe concurrent message processing
+- **Persistent Configuration**: KV store-based persistence for mappings and user data
+- **Admin Security**: System administrator access control for all operations
+

+- **Mattermost Bridge** (`server/bridge/mattermost/`): Internal Mattermost API integration
+- **Message Handlers**: Protocol-specific message processing
+- **User Resolvers**: User identity mapping and resolution
+
+## Communication Patterns
+
+### Message Flow Patterns
+1. **Producer-Consumer**: Bridges produce/consume messages via message bus
+2. **Request-Response**: Command processing with immediate feedback
+3. **Event-Driven**: Configuration changes trigger bridge updates
+4. **Publisher-Subscriber**: Message bus routes to all interested bridges
+
+### Concurrency Patterns
+1. **Goroutine Pools**: Per-bridge message processing
+2. **Channel-Based Communication**: Non-blocking message queues
+3. **Context Cancellation**: Graceful shutdown coordination
+4. **WaitGroup Synchronization**: Coordinated cleanup operations
+
+## Data Persistence
+
+### Storage Strategy
+- **KV Store Abstraction**: Pluggable storage backend
+- **Structured Keys**: Hierarchical key naming for efficient queries
+- **Bridge-Agnostic Schema**: Support for multiple bridge types
+- **Migration Support**: Versioned schema for backward compatibility
+
+### Key Patterns
+```
+channel_map_{bridge}_{identifier} → channel_id
+{bridge}_user_{external_id} → mattermost_user_id  
+ghost_user_{mattermost_user_id} → ghost_jid
+{bridge}_event_post_{event_id} → post_id
+```
+
+## Error Handling & Resilience
+
+### Failure Modes
+1. **Connection Failures**: Automatic reconnection with backoff
+2. **Message Delivery Failures**: Timeout handling with retry logic
+3. **Configuration Errors**: Validation with user-friendly error messages
+4. **Storage Failures**: Graceful degradation with logging
+
+### Recovery Strategies
+1. **Circuit Breaker Pattern**: Prevent cascade failures
+2. **Graceful Degradation**: Continue operation with reduced functionality
+3. **Health Checks**: Proactive problem detection
+4. **Comprehensive Logging**: Structured logging for debugging
+
+## Performance Considerations
+
+### Scalability Features
+1. **Buffered Channels**: 1000-message buffers prevent blocking
+2. **Message Aggregation**: Multiple message sources per bridge
+3. **Concurrent Processing**: Parallel message handling
+4. **Connection Pooling**: Efficient resource utilization
+
+### Optimization Techniques
+1. **Lazy Initialization**: Components created on demand
+2. **Caching Strategies**: In-memory mapping cache
+3. **Batch Operations**: Bulk message processing where possible
+4. **Resource Cleanup**: Proper goroutine lifecycle management
+
+## Security Model
+
+### Access Control
+- **Admin-Only Commands**: System administrator privilege requirement
+- **Bridge Isolation**: Separate security contexts per bridge
+- **Credential Management**: Secure storage of authentication data
+- **TLS Configuration**: Configurable certificate validation
+
+### Data Protection
+- **Secure Storage**: Plugin KV store encryption
+- **Message Privacy**: No message content logging
+- **User Privacy**: Minimal personal data storage
+- **Audit Trail**: Command execution logging
+
+## Testing Strategy
+
+### Unit Testing
+- **Component Isolation**: Mock dependencies for focused testing
+- **Interface Testing**: Bridge interface compliance verification
+- **Message Processing**: End-to-end message flow validation
+- **Error Scenarios**: Comprehensive failure mode testing
+
+### Integration Testing
+- **XMPP Testcontainers**: Automated XMPP server testing
+- **Bridge Integration**: Multi-bridge message routing tests
+- **Configuration Testing**: Settings validation and propagation
+- **Performance Testing**: Load testing with gotestsum
+- **XEP Feature Testing**: Doctor command with comprehensive XEP-0077 validation
+- **Live Server Testing**: Real user account creation and deletion tests
+
+## Extension Points
+
+### Adding New Bridges
+
+1. **Implement Bridge Interface**:
+```go
+type MyBridge struct {
+    // Bridge-specific fields
+}
+
+func (b *MyBridge) Start() error { /* implementation */ }
+func (b *MyBridge) GetMessageChannel() <-chan *DirectionalMessage { /* implementation */ }
+// ... other Bridge interface methods
+```
+
+2. **Create Message Handler**:
+```go
+type myMessageHandler struct {
+    bridge *MyBridge
+}
+
+func (h *myMessageHandler) ProcessMessage(msg *DirectionalMessage) error {
+    // Process incoming messages from other bridges
+}
+```
+
+3. **Register with Bridge Manager**:
+```go
+myBridge := mybridge.NewBridge(logger, api, kvstore, config)
+bridgeManager.RegisterBridge("mybridge", myBridge)
+```
+
+### Message Type Extensions
+- **Rich Content**: Extend BridgeMessage for files, images, reactions
+- **Custom Metadata**: Bridge-specific message properties
+- **Format Converters**: Content transformation between protocols
+- **Message Filtering**: Content-based routing rules
+
+## Deployment & Operations
+
+### Plugin Lifecycle
+1. **Installation**: Plugin bundle deployment to Mattermost
+2. **Configuration**: Admin console settings configuration
+3. **Activation**: Component initialization and bridge startup
+4. **Operation**: Real-time message synchronization
+5. **Updates**: Hot configuration reload without restart
+6. **Maintenance**: Health monitoring and log analysis
+
+### Monitoring & Observability
+- **Health Endpoints**: Bridge connectivity status
+- **Structured Logging**: JSON-formatted log entries
+- **Metrics Collection**: Message throughput and error rates
+- **Alerting**: Failed connection and mapping error notifications
+
+## Development Workflow
+
+### Prerequisites
+- Go 1.21+ for server development
+- Node.js 18+ for webapp development
+- Docker for XMPP test server
+- golangci-lint for code quality
+
+### Key Commands
+```bash
+make                    # Build plugin bundle
+make test              # Run all tests
+make check-style       # Lint and format
+make deploy           # Deploy to local Mattermost
+make devserver_start  # Start test XMPP server
+```
+
+### XMPP Client Doctor Tool (`cmd/xmpp-client-doctor/`)
+The doctor command provides comprehensive XMPP connectivity and feature testing:
+
+```bash
+# Basic connectivity test
+go run ./cmd/xmpp-client-doctor/main.go
+
+# Test specific features
+go run ./cmd/xmpp-client-doctor/main.go --test-xep0077 --test-muc --test-dm
+
+# Custom server testing  
+go run ./cmd/xmpp-client-doctor/main.go --server example.com:5222 --username user@example.com
+```
+
+### Code Organization
+```

Felipe Martin	d9c0215b93	feat: implement comprehensive loop prevention and architecture improvements - Add comprehensive loop prevention at source level for all bridges: - XMPP bridge: Skip messages from own XMPP connection user - Mattermost bridge: Skip messages from bot user and remote users - Remove cache from getOrCreateRemoteUser method for simplified user management - Improve XMPP client architecture with direct handler delegation: - Add SetMessageHandler and GetJID methods to XMPP client - Move protocol normalization methods to client level - Implement handleIncomingXMPPMessage in XMPP bridge for business logic - Fix message direction handling in XMPP message handler - Add remote user invitation to shared channels via InviteRemoteToChannel API - Clean up unused code and improve code formatting 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-08-06 17:16:52 +02:00
Felipe Martin	11a32afc53	refactor: improve XMPP client/bridge architecture separation - Move protocol normalization methods to XMPP client (ExtractChannelID, ExtractUserInfo, ExtractMessageBody) - Replace message channel aggregation with direct handler delegation pattern - XMPP client now focuses purely on protocol concerns (connection, deduplication, normalization) - XMPP bridge handles business logic (BridgeMessage creation, routing) - Add SourceRemoteID field to BridgeMessage for better message tracking - Remove unused message channel infrastructure in favor of mux.MessageHandlerFunc pattern 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-08-06 12:31:28 +02:00
Felipe Martin	8e9d87b176	feat: implement remote user creation for Mattermost bridge Replace bot-based message posting with remote user creation system: - Add getOrCreateRemoteUser() method to create/retrieve remote users on-demand - Use plugin API to find existing users by username/email before creating new ones - Generate usernames with bridge prefix and emails with bridge.{bridgeID} domain - Set RemoteId field to BridgeMessage.SourceRemoteID for proper loop prevention - Cache user mappings to avoid repeated API calls - Post messages directly as remote users instead of bot with metadata - Remove unused message formatting since messages are posted as actual users - Log errors for failed user creation without complex retry logic This enables authentic user attribution in Mattermost channels while maintaining existing loop prevention mechanisms through the RemoteId field. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>	2025-08-06 12:29:55 +02:00
