Aspectran 9.6 Release Notes

This release focuses on adding dependsOn support for the IoC container, introducing a job locking mechanism for distributed environments, and a complete overhaul of the wildcard matching engine. Various features have been added and the internal architecture improved to enhance stability and operational efficiency in enterprise environments.

✨ New Features

• Added Bean Dependency Control (dependsOn)
  • Supported the dependsOn attribute across all configuration formats (XML, APON, Annotation) to guarantee explicit initialization and destruction sequences between beans.
  • Introduced circular dependency detection to prevent configuration errors and ensure stable lifecycle management.
• Introduction of Job Locking Mechanism for Distributed Scheduling
  • Introduced the ScheduledJobLockProvider interface and job locking mechanism to prevent redundant execution of scheduled jobs in clustered environments.
  • This allows integration of external locking providers to control job execution across nodes.
• Enhanced Schedule and Job Control Attributes
  • Added isolated and disabled attributes to schedules and individual jobs to enhance runtime control capabilities.
• Dynamic Encryption Configuration Reloading
  • Refactored PBEncryptionUtils to detect system property changes in real-time and reload configurations accordingly.
  • Added support for fixed salts and per-operation custom salt application to increase security configuration flexibility.
• Introduction of TestCoreService for Integration Testing
  • Introduced a dedicated service to simplify and standardize context bootstrapping and lifecycle management during testing.

🚀 Improvements

• Comprehensive Refactoring of the Wildcard Matching Engine (WildcardEngine)
  • Implemented a sophisticated backtracking algorithm to significantly improve the accuracy of complex pattern matching and masking.
  • Fully supports “separator swallowing” for double asterisks (**) matching empty segments.
• Standardization of REST Response and Payload Structure
  • Refined the structure of ResponsePayload and ErrorPayload to dynamically include fields based on success or failure status.
• Refinement of Daemon Service Architecture and Command Execution Structure
  • Separated command execution logic into explicit synchronous and asynchronous roles and integrated management functions into the DaemonService layer.
• Centralized AsEL Expression Evaluation
  • Added methods to the Activity and Translet interfaces to allow direct evaluation of AsEL expressions and unified the underlying logic.

🐞 Bug Fixes

• Wildcard Engine Matching Fixes
  • Resolved issues where cross-segment wildcards incorrectly consumed subsequent literal parts.
• Improved Pattern Matching Accuracy
  • Corrected the behavior of ‘?’ and ‘+’ wildcards to align with their definitions.
• Daemon Command Isolation Rules
  • Fixed inconsistencies in the processing logic for isolated and slow command files in daemon services.
