* Add debug info to assertion messages for root cause analysis
* Fix flaky timeout assertion in maintenance notification test
* Apply same tolerance fix to NORMAL_COMMAND_TIMEOUT assertions
* rename maint options according to the latest client options
* adjust env variables
cae repo uses RE_FAULT_INJECTOR_URL for fault injector
DATABASE_NAME is needed to choose from the many databases in cae
* fix connection cleanup test
* feat(errors): Add specialized timeout error types for maintenance scenarios
- Added `SocketTimeoutDuringMaintananceError`, a subclass of `TimeoutError`, to handle socket timeouts during maintenance.
- Added `CommandTimeoutDuringMaintenanceError`, another subclass of `TimeoutError`, to address command write timeouts during maintenance.
* feat(linked-list): Add EmptyAwareSinglyLinkedList and enhance DoublyLinkedList functionality
- Introduced `EmptyAwareSinglyLinkedList`, a subclass of `SinglyLinkedList` that emits an `empty` event when the list becomes empty due to `reset`, `shift`, or `remove` operations.
- Added `nodes()` iterator method to `DoublyLinkedList` for iterating over nodes directly.
- Enhanced unit tests for `DoublyLinkedList` and `SinglyLinkedList` to cover edge cases and new functionality.
- Added comprehensive tests for `EmptyAwareSinglyLinkedList` to validate `empty` event emission under various scenarios.
- Improved code formatting and consistency.
* refactor(commands-queue): Improve push notification handling
- Replaced `setInvalidateCallback` with a more flexible `addPushHandler` method, allowing multiple handlers for push notifications.
- Introduced the `PushHandler` type to standardize push notification processing.
- Refactored `RedisCommandsQueue` to use a `#pushHandlers` array, enabling dynamic and modular handling of push notifications.
- Updated `RedisClient` to leverage the new handler mechanism for `invalidate` push notifications, simplifying and decoupling logic.
* feat(commands-queue): Add method to wait for in-flight commands to complete
- Introduced `waitForInflightCommandsToComplete` method to asynchronously wait for all in-flight commands to finish processing.
- Utilized the `empty` event from `#waitingForReply` to signal when all commands have been completed.
* feat(commands-queue): Introduce maintenance mode support for commands-queue
- Added `#maintenanceCommandTimeout` and `setMaintenanceCommandTimeout` method to dynamically adjust command timeouts during maintenance
* refator(client): Extract socket event listener setup into helper method
* refactor(socket): Add maintenance mode support and dynamic timeout handling
- Added `#maintenanceTimeout` and `setMaintenanceTimeout` method to dynamically adjust socket timeouts during maintenance.
* feat(client): Add Redis Enterprise maintenance configuration options
- Added `maintPushNotifications` option to control how the client handles Redis Enterprise maintenance push notifications (`disabled`, `enabled`, `au
to`).
- Added `maintMovingEndpointType` option to specify the endpoint type for reconnecting during a MOVING notification (`auto`, `internal-ip`, `external-ip`,
etc.).
- Added `maintRelaxedCommandTimeout` option to define a relaxed timeout for commands during maintenance.
- Added `maintRelaxedSocketTimeout` option to define a relaxed timeout for the socket during maintenance.
- Enforced RESP3 requirement for maintenance-related features (`maintPushNotifications`).
* feat(client): Add socket helpers and pause mechanism
- Introduced `#paused` flag with corresponding `_pause` and `_unpause` methods to
temporarily halt writing commands to the socket during maintenance windows.
- Updated `#write` method to respect the `#paused` flag, preventing new commands from being written during maintenance.
- Added `_ejectSocket` method to safely detach from and return the current socket
- Added `_insertSocket` method to receive and start using a new socket
* feat(client): Add Redis Enterprise maintenance handling capabilities
- Introduced `EnterpriseMaintenanceManager` to manage Redis Enterprise maintenance events and push notifications.
- Integrated `EnterpriseMaintenanceManager` into `RedisClient` to handle maintenance push notifications and manage socket transitions.
- Implemented graceful handling of MOVING, MIGRATING, and FAILOVER push notifications, including socket replacement and timeout adjustments.
* test: add E2E test infrastructure for Redis maintenance scenarios
* test: add E2E tests for Redis Enterprise maintenance timeout handling (#3)
* test: add connection handoff test
