- Fix build_kv_cache method in hf.py to handle both old and new DynamicCache structures
  - Support new 'layers' attribute with key_cache/value_cache or keys/values
  - Maintain backward compatibility with direct key_cache/value_cache attributes
  - Add comprehensive error handling and logging for unsupported structures

- Update move_dynamic_cache_htod function in kv.py for cross-version compatibility
  - Handle layers-based structure in newer transformers versions
  - Support alternative attribute names (keys/values vs key_cache/value_cache)
  - Preserve original functionality for older transformers versions

- Add comprehensive tests for DynamicCache compatibility
  - Test activation memory update with mock DynamicCache layers
  - Verify layers attribute access across different transformers versions
  - Fix scheduler logger mock to include memory_manager attribute
This resolves AttributeError issues when using different versions of the
transformers library and ensures robust handling of DynamicCache objects.

debug
- Add APIAnalyzerForScheduler class with search/add operations
- Support requests and http.client with connection reuse
- Include comprehensive error handling and dynamic configuration
- Add English test suite with real-world conversation scenarios
- Add search_ws endpoint in server_router.py for scheduler-enabled search
- Fix missing imports: time module, SearchRequest class, and get_mos_product_instance function
- Implement search_ws method in api_analyzer.py with HTTP client support
- Add _search_ws_with_requests and _search_ws_with_http_client private methods
- Include search_ws usage example in demonstration code
- Enhance scheduler and dispatcher capabilities for improved memory management
- Expand test coverage to ensure functionality stability

This update primarily strengthens the memory scheduling system's search capabilities,
providing users with more flexible API interface options.
- Fix Pydantic serialization warning in test_memos_chen_tang_hello_world
  * Add warnings filter to suppress UserWarning from Pydantic serialization

- Fix KeyError: 'past_key_values' in test_build_kv_cache_and_generation
  * Update mock configuration to properly return forward_output with past_key_values
  * Add DynamicCache version compatibility handling in test mocks
  * Support both old and new transformers versions with layers/key_cache attributes
  * Improve assertion logic to check all model calls for required parameters

- Update base_scheduler.py to use centralized DEFAULT_MAX_INTERNAL_MESSAGE_QUEUE_SIZE constant
  * Add import for DEFAULT_MAX_INTERNAL_MESSAGE_QUEUE_SIZE from general_schemas
  * Replace hardcoded value 100 with configurable constant (1000)

All tests now pass successfully with proper version compatibility handling.
- Add DEFAULT_TOP_K and DEFAULT_CONTEXT_WINDOW_SIZE global constants in general_schemas.py
- Update base_scheduler.py to use global default values instead of hardcoded numbers
- Fix SchedulerConfigFactory initialization issue by using keyword argument expansion
- Resolve UnboundLocalError variable conflict in search_memories_ws function
- Fix indentation and parameter issues in OptimizedScheduler search_for_api method
- Improve code standardization and maintainability
- Add auto_initialize_redis() with config/env/local fallback
- Move Redis logic from dispatcher_monitor to redis_service
- Update base_scheduler to use auto initialization
- Add proper resource cleanup and error handling
- Add MySQL engine loading from environment variables in BaseDBManager
- Add Redis connection loading from environment variables in BaseDBManager
- Enhance database configuration validation and error handling
- Complete database adapter infrastructure for ORM module
- Provide unified database connection management interface

This update provides comprehensive database connection management capabilities
for the mem_scheduler module, supporting dynamic MySQL and Redis configuration
loading from environment variables, establishing reliable data persistence
foundation for scheduling services and API services.
- Add RedisDBManager and RedisLockableORM classes
- Implement atomic locking mechanism for concurrent access
- Add merge functionality for different object types
- Include comprehensive test suite and examples
- Fix Redis key type conflicts in lock operations
…I with reranker

- Fix running_entries to running_task_ids migration across codebase
- Update sync_search_data method to properly handle TaskRunningStatus
- Correct variable naming and logic in API synchronization flow
- Implement search API endpoint with reranker functionality
- Update test files to reflect new running_task_ids convention
- Ensure proper Redis state management for concurrent tasks
    - Add conversation_turn field to APIMemoryHistoryEntryItem schema with default value 0
    - Implement session counter in OptimizedScheduler to track turn count per session_id
    - Update sync_search_data method to accept and store conversation_turn parameter
    - Maintain session history with LRU eviction (max 5 sessions)
    - Rename conversation_id to session_id for consistency with request object
    - Enable direct access to session_id from search requests

    This feature allows tracking conversation turns within the same session,
    providing better context for memory retrieval and search history management.

Fix(Scheduler): Correct create_event_log indentation
Reverts previous incorrect fix to scheduler_logger.py and correctly fixes the TypeError at the call sites in general_scheduler.py by removing the invalid 'log_content' kwarg and adding the missing memory_type kwargs.
This completes the fix for the task_id loss. The 'to_dict' method was previously fixed to serialize the task_id, but the corresponding 'from_dict' method was not updated to deserialize it, causing the value to be lost when messages were read from the queue.
Moves all environment variable override logic into initialize_rabbitmq for a single source of truth. This ensures Nacos-provided environment variables for all RabbitMQ settings are respected over file configurations. Also removes now-redundant logging from the publish method.
Resolves DataError in Redis Streams when task_id is None by ensuring
it's serialized as an empty string instead of None, which Redis does
not support. Applies to ScheduleMessageItem.to_dict method.
Adds an INFO level diagnostic log message at the beginning of the
create_memory function to help verify code deployment.
Introduces detailed INFO level diagnostic logs across the entire call chain
for the /product/add API endpoint. These logs include relevant context,
such as full request bodies, message items before scheduler submission,
and messages before RabbitMQ publication, to aid in debugging deployment
discrepancies and tracing data flow, especially concerning task_id
propagation.
