- Add protected flag to RegisterHandler methods across all types
- Protected handlers cannot be unregistered, UnregisterHandler returns error
- Rename 'command' parameter to 'pushNotificationName' for clarity
- Update PushNotificationInfo.Command field to Name field
- Add comprehensive test for protected handler functionality
- Update all existing tests to use new protected parameter (false by default)
- Improve error messages to use 'push notification' terminology
Benefits:
- Critical handlers can be protected from accidental unregistration
- Clearer naming reflects that these are notification names, not commands
- Better error handling with informative error messages
- Backward compatible (existing handlers work with protected=false)
- Add sync.RWMutex to PushNotificationProcessor struct
- Protect enabled field access with read/write locks in IsEnabled() and SetEnabled()
- Use thread-safe IsEnabled() method in ProcessPendingNotifications()
- Fix concurrent access to enabled field that was causing data races
This resolves the race condition between goroutines calling IsEnabled() and
SetEnabled() concurrently, ensuring thread-safe access to the enabled field.
- Remove RegisterPushNotificationHandlerFunc methods from all types
- Remove PushNotificationHandlerFunc type adapter
- Keep only RegisterPushNotificationHandler method for cleaner interface
- Remove unnecessary push notification constants (keep only Redis Cluster ones)
- Update all tests to use simplified interface with direct handler implementations
Benefits:
- Cleaner, simpler API with single registration method
- Reduced code complexity and maintenance burden
- Focus on essential Redis Cluster push notifications only
- Users implement PushNotificationHandler interface directly
- No functional changes, just interface simplification
- Remove unused Timestamp and Source fields from PushNotificationInfo
- Add pushProcessor to newConn function to ensure Conn instances have push notifications
- Add push notification methods to Conn type for consistency
- Ensure cloned clients and Conn instances preserve push notification functionality
This fixes issues where:
1. PushNotificationInfo had unused fields causing confusion
2. Conn instances created via client.Conn() lacked push notification support
3. All client types now consistently support push notifications
- Remove all global push notification handler functionality
- Simplify registry to support only single handler per notification type
- Enable push notifications by default for RESP3 connections
- Update comprehensive test suite to remove global handler tests
- Update demo to show multiple specific handlers instead of global handlers
- Always respect custom processors regardless of PushNotifications flag
Push notifications are now automatically enabled for RESP3 and each
notification type has a single dedicated handler for predictable behavior.
- Change PushNotificationRegistry to allow only one handler per command
- RegisterHandler methods now return error if handler already exists
- Update UnregisterHandler to remove handler by command only
- Update all client methods to return errors for duplicate registrations
- Update comprehensive test suite to verify single handler behavior
- Add specific test for duplicate handler error scenarios
This prevents handler conflicts and ensures predictable notification
routing with clear error handling for registration conflicts.
- Add PushNotificationRegistry for managing notification handlers
- Add PushNotificationProcessor for processing RESP3 push notifications
- Add client methods for registering push notification handlers
- Add PubSub integration for handling generic push notifications
- Add comprehensive test suite with 100% coverage
- Add push notification demo example
This system allows handling any arbitrary RESP3 push notification
with registered handlers, not just specific notification types.
