Checkpoint Groups for Dynamic Assertion Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for activating assertions and breakpoints in computer programs often hinder performance and are undesirable in live applications, as they can disrupt execution and are not easily managed in terms of location or activation scope.
Innovation Solution
The implementation of checkpoint groups and activation variants allows for dynamic activation and deactivation of assertions and breakpoints during runtime, enabling programmer-controlled logging and execution modes, with options to terminate, halt, or log failures, and managing these elements independently of their location in the code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If assertions and breakpoints are executed as part of program code, then debugging and consistency checks are improved, but performance deteriorates
Solution Approach 1:
The patent implements dynamic activation and deactivation of assertions and breakpoints through checkpoint groups. The system allows these debugging features to be turned on or off at runtime based on execution context, enabling them to be active only when needed for debugging rather than continuously, thus resolving the performance contradiction.
Solution Approach 2:
The patent employs periodic activation of assertions and breakpoints through checkpoint groups that can be selectively enabled or disabled. Rather than continuous execution, the debugging features are activated in periodic intervals or specific phases of program execution, reducing overall performance impact while maintaining debugging effectiveness.
2Reliability
If assertions and breakpoints are activated for all code locations, then debugging coverage is improved, but management complexity increases
Solution Approach 1:
The patent merges multiple scattered checkpoints into grouped units that can be managed collectively. By organizing assertions and breakpoints into checkpoint groups, the system reduces the number of individual management operations needed while maintaining comprehensive debugging coverage across the codebase.
Solution Approach 2:
The patent creates checkpoint groups that serve multiple functions simultaneously - they can be activated globally, restricted to specific users, limited to particular servers, or applied selectively. This multi-functionality allows a single checkpoint group structure to handle various debugging scenarios without increasing management complexity.
3Productivity
If assertions and breakpoints are deactivated in live applications, then performance is improved, but debugging capability is lost
Solution Approach 1:
The patent implements dynamic switching between active and inactive states for checkpoint groups in live applications. The system allows runtime control where checkpoint groups can be deactivated for performance optimization while remaining available for reactivation when debugging is needed, resolving the contradiction between performance and debugging availability.
Data Source
AI summary
Methods and apparatus, including computer program products, for activating assertions and breakpoints. The techniques include establishing any number of checkpoints in a first computer program; and including each checkpoint in a checkpoint group, wherein each checkpoint group can include any number of the checkpoints regardless of where the checkpoints are in the first computer program. The checkpoints can include assertion statements and breakpoint statements. Activation variants enable checkpoint groups or compilation units or both to be managed jointly.
