dart_faye 1.2.2

A complete Dart implementation of Faye, a publish-subscribe messaging system that implements the Bayeux protocol.

Changelog

1.2.2

Bug Fixes

• Bayeux Response Handling: Fixed critical bug where the package failed to handle Bayeux protocol responses that come as JSON arrays
  • Added extractBayeuxMessage() helper function to handle both single object and array responses
  • Updated HTTP transport, Client, and Dispatcher to properly handle array responses
  • Fixed "type 'String' is not a subtype of type 'int' of 'index'" error when accessing response properties
  • Enhanced HTTP transport's send() method to properly handle responses for immediate requests
  • Added comprehensive tests for Bayeux response handling scenarios
  • Made the package compatible with servers that return responses in the standard Bayeux array format

Technical Improvements

• Added helper functions for consistent Bayeux response handling across all components
• Enhanced error handling for empty arrays and invalid response types
• Improved compatibility with various Bayeux server implementations
• Added test coverage for response handling edge cases

1.2.1

Maintenance

• Fixed repository urls

1.2.0

Features

• Enhanced Extension Support: Improved extension processing for both incoming and outgoing messages
  • Extension processing now applied to incoming messages in Client
  • Better error handling and logging for extension operations
  • Extension type and method availability logging for debugging
• Improved Subscription State Management: Enhanced subscription handling during connection phases
  • Allow subscriptions during connecting state (not just connected state)
  • Better support for extensions that need to subscribe during handshake response processing
  • More robust state validation for subscription operations

Bug Fixes

• Extension Access: Added proper extension getter in Dispatcher for Client access
• Message Processing: Fixed extension processing in incoming message handling
• State Management: Improved connection state handling for subscription operations

Technical Improvements

• Enhanced logging for extension operations and debugging
• Better error handling in extension processing
• Improved state validation for subscription operations
• More comprehensive extension integration throughout the message flow

1.1.0

Features

• Extension Support: Added support for Faye extensions to enable authentication and message transformation
  • New setExtension() method on Client and Dispatcher classes
  • Extension processing in outgoing messages for authentication headers
  • Support for custom extension classes implementing outgoing() and incoming() methods
• Comprehensive Logging: Added extensive logging throughout the package for debugging
  • Logger integration in Client, Dispatcher, and Transport classes
  • Detailed connection state tracking and error reporting
  • Debug information for message processing and extension handling
• Improved WebSocket Transport: Enhanced WebSocket transport reliability
  • Better handling of batch messages (arrays) from server responses
  • Improved connection order (transport connection before handshake)
  • Automatic transport selection for WebSocket URLs (wss://, ws://)
  • Removed protocol restrictions to allow server protocol selection

Bug Fixes

• Connection Order: Fixed dispatcher to connect transport before handshake
• State Constants: Corrected state constant usage (integer values instead of enum-like constants)
• Message Processing: Fixed extension message processing to ensure modified messages are returned
• Batch Message Handling: Added support for server responses in array format
• Transport Selection: Improved automatic transport selection logic

Technical Improvements

• Enhanced error handling and debugging capabilities
• Better integration with Flutter applications
