Binary Interface Instrumentation via Metadata Compatibility Checking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compiler systems lack a mechanism to determine compatibility between binary objects generated from different source codes, leading to potential runtime failures that are difficult and costly to diagnose.
Innovation Solution
A system and method that generates metadata from source code and compares it to determine compatibility between binary objects, considering factors like operating systems, compiler versions, and machine characteristics, using a metadata-generating compilation toolkit that includes a compiler, linker, metadata processor, and comparison engine to create and analyze metadata files.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compiler systems generate binary objects from different source codes without compatibility checking mechanisms, then compilation speed and simplicity are maintained, but runtime reliability deteriorates due to potential incompatibilities
Solution Approach 1:
The system performs compatibility checking during the compilation phase before deployment, generating metadata files that document binary object characteristics. This preliminary action prevents runtime failures by identifying incompatibilities early in the development cycle, resolving the contradiction between reliability and complexity by shifting the checking mechanism to an earlier stage in the software lifecycle.
Solution Approach 2:
The patent introduces metadata files as intermediary artifacts between the compiler and the binary objects. These metadata files contain structured information about compiler versions, optimization settings, and binary characteristics, serving as a mediator that enables compatibility verification without requiring direct complex analysis of the binary objects themselves.
2Difficulty of detecting and measuring
If no metadata generation and comparison mechanism is implemented, then compilation process remains simple and fast, but diagnostic capability for runtime failures deteriorates
Solution Approach 1:
The system generates and stores metadata files during compilation that document all relevant binary object characteristics including compiler version, optimization flags, and platform-specific parameters. This preliminary documentation enables rapid compatibility assessment later by comparing metadata rather than performing time-consuming binary analysis, thus reducing diagnostic time while improving detection capability.
Solution Approach 2:
The patent replaces direct binary object analysis with metadata-based comparison. Instead of examining the complex binary structures directly when diagnosing compatibility issues, the system uses lightweight metadata files that contain extracted characteristics, substituting a complex mechanical analysis process with a simpler data comparison operation.
3Measurement precision
If comprehensive metadata is generated and compared for all binary objects, then compatibility accuracy is improved, but processing overhead and system complexity increase
Solution Approach 1:
The system extracts only the essential compatibility-relevant characteristics from the full binary object information and stores them in metadata files. Rather than analyzing or comparing entire binary objects, the compiler extracts key parameters such as compiler version, optimization level, target architecture, and ABI compatibility markers, taking out only the necessary information for compatibility assessment.
Solution Approach 2:
The metadata files contain differentiated information with varying levels of detail based on the specific binary object and its intended use. Not all binary objects require the same level of metadata granularity, and the system applies local quality by including only the necessary compatibility attributes for each specific case rather than uniform comprehensive metadata for all objects.
Data Source
AI summary
A system and methods for generating metadata based on source code are disclosed. In accordance with one embodiment, a computer system receives a command to compile source code, and in response to the command, generates an executable and a metadata file based on the source code, where the metadata file comprises information pertaining to at least one of a scalar type of the source code, a variable of the source code, or a function of the source code.
