Previously, NoiseSessionManager would reject handshake initiations if it had an existing established session. This caused deadlocks when one peer cleared their session (e.g., after decryption failure) but the other peer rejected the new handshake.
Changes:
- NoiseSessionManager now always accepts handshake initiations, clearing any existing session
- Added comprehensive tests for handshake recovery scenarios
- Tests verify proper re-establishment after decryption failures and nonce desynchronization
- Add test for peer restart detection and session recovery
- Add test for nonce desynchronization detection
- Add test for concurrent encryption thread safety
- Add test for session stale detection
- Add test for handshake after decryption failure
- Add integration test for peer presence tracking and reconnection
- Add integration test for encrypted messages after peer restart
These tests ensure:
- Sessions properly recover when a peer restarts
- Nonce desynchronization is detected correctly
- Encryption operations are thread-safe under concurrent load
- Identity announcements are sent on reconnection after silence
- Encrypted messages work after session re-establishment
- Fixed mock service property overrides to match base class properties
- Added missing CryptoKit imports where needed
- Fixed immutable property assignments by creating new instances
- Replaced XCTAssertThrows with XCTAssertThrowsError
- Fixed DeliveryAck serialization method names (serialize -> encode)
- Fixed unused variable warnings
- Ensured all BitchatPacket modifications create new instances
- Fixed BitchatMessage property mutations by creating new instances
All test targets now build successfully for both iOS and macOS platforms.
- Created test utilities and helpers for common test operations
- Implemented Binary Protocol tests covering encoding/decoding, compression, and padding
- Added Noise Protocol tests for handshake, encryption, and session management
- Created Public Chat E2E tests for broadcasting, routing, TTL, and mesh topologies
- Implemented Private Chat E2E tests for direct messaging, delivery ACKs, and retry logic
- Added Integration tests for multi-peer scenarios, network resilience, and mixed traffic patterns
- Created mock implementations for BluetoothMeshService and NoiseSession
Test coverage includes:
- Protocol layer (binary encoding, message serialization)
- Security layer (Noise handshake, encryption/decryption)
- Application layer (public/private messaging, delivery tracking)
- Network scenarios (mesh topology, partitions, churn)
- Performance and stress testing
- Remove channel UI elements from ContentView
- Remove channel data structures and methods from ChatViewModel
- Remove channel commands (/j, /leave, /channels)
- Remove channel field from BitchatMessage protocol
- Remove channel message types and handling
- Remove NoiseChannelEncryption.swift entirely
- Clean up all channel references across the codebase
- Fix compilation warnings (var to let conversions)
- Remove all outdated test files that used incorrect APIs
- Simplify app to only support public broadcast and 1:1 private messages
- Rename SecurityLogger to SecureLogger for better clarity
- Add file:line:function tracking to all log entries
- Optimize logging with pre-compiled regex patterns and NSCache
- Add comprehensive logging for critical protocol flow points
- Fix iOS entitlements to include Bluetooth permission
- Fix VersionHello field name and optional chaining issues
- Fix Package.swift resource warnings
- Fix test compilation errors with proper type annotations
- Remove NoisePostQuantum.swift entirely (placeholder with no implementation)
- Remove Double Ratchet placeholder code from NoiseChannelKeyRotation.swift
- Remove NoisePostQuantumTests that tested mock implementations
- Handle TODO for version negotiation rejection (now properly disconnects)
- Remove legacy comment about removed message type 0x02
- Keep deprecated ownerID field as it's still used for compatibility
This cleanup removes ~400 lines of placeholder code that was not
being used and unlikely to be implemented in the near future.
- Add version negotiation messages (0x20 versionHello, 0x21 versionAck)
- Implement VersionHello and VersionAck message types with platform info
- Add ProtocolVersion struct for version management and negotiation
- Update BinaryProtocol to check supported versions
- Add version negotiation to connection flow before Noise handshake
- Maintain backward compatibility with legacy peers (assume v1)
- Add comprehensive test suite with 40+ test cases
- Update documentation with version negotiation details
This ensures BitChat clients can negotiate protocol versions for smooth
upgrades while maintaining full backward compatibility with existing clients.
- Changed system messages from green to grey with consistent 12pt font

- Added welcome message for new users (3 second delay)
- Changed sidebar header to 'YOUR NETWORK'
- Added command aliases (/join, /msg)
- Implemented /hug and /slap commands with haptic feedback
- Improved command help display with alphabetization
- Renamed 'rooms' to 'channels' throughout entire codebase
- Add LZ4 message compression for 30-70% bandwidth reduction

- Add comprehensive tests for new functionality
This update significantly improves the security and usability of
password-protected rooms by allowing immediate verification without
waiting for encrypted messages.
