Inline Expansion Metadata Validation for Software Component Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When software components are updated and shipped separately, inline expansion can lead to execution issues due to outdated inlined code, prompting a trade-off between performance benefits and component updates, where either performance is compromised or inline expansion is not used.
Innovation Solution
A mechanism where a copy of the inlined method from the first software component is stored in metadata attached to the second software component, with validation instructions to ensure the method has not been updated before execution, allowing for the execution of the original method if updates are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If inline expansion is used to improve system performance, then system performance is improved, but the software component cannot be updated separately causing execution issues
Solution Approach 1:
The patent segments the inlined code by storing it in a separate metadata structure (e.g., .metafile) rather than embedding it directly in the executable. This allows the inlined code to be stored independently and updated separately from the main software component, resolving the contradiction between performance optimization and update capability.
Solution Approach 2:
The patent introduces a metadata structure as an intermediary between the executable code and the inlined method. This metadata acts as a bridge that stores the inlined code separately and provides validation mechanisms, enabling both performance benefits of inlining and separate update capability.
2Reliability
If inline expansion is not used to maintain component update capability, then component updates are possible, but system performance deteriorates due to function-calling-overhead
Solution Approach 1:
By segmenting the inlined code into separate metadata that can be independently updated, the system maintains both update capability and performance. The metadata structure allows the inlined code to be refreshed without recompiling the main executable.
Solution Approach 2:
The patent makes the inlined code dynamic by allowing it to be updated at runtime through separate component updates. The metadata structure enables the inlined code to change without requiring a full system rebuild, combining the benefits of static inlining with dynamic update capability.
3Reliability
If a validation process is added to check for updates before execution, then component update reliability is improved, but system complexity increases
Solution Approach 1:
The patent performs validation in advance by storing a copy of the inlined code in metadata before execution. The system checks whether the inlined code matches the current component version before running, preventing execution of outdated code without adding complex runtime validation logic.
Solution Approach 2:
The patent creates a copy of the inlined code and stores it in metadata alongside validation information. This copy is used to validate whether the component has been updated, providing a simple and efficient validation mechanism that does not significantly increase system complexity.
Data Source
AI summary
A computing system and method for determining if a first software component that has shipped separately from a second software component has been updated. An inline expansion process copies a first method of the first software component into a first method of a second software component is performed so that the copied first method is executable when the second method of the second software component is executed. The first method from the first software component is copied into metadata that is attached to the first method of the second software component. The copy of the first method in the metadata is used to validate that the first method in the first software component has not been updated.
