Versioning System Module Abstract

High-level Purpose and Responsibility

The versioning system module implements semantic versioning standards and comparison algorithms for the experimental learning platform. It provides systematic version number management, compatibility rules, and version ordering logic that supports reproducible science and controlled system evolution.

Key Data Structures and Relationships

  • Version: Semantic version representation with major, minor, and patch components
  • VersionRequirement: Specification of acceptable version ranges and constraints
  • VersionComparison: Algorithms for ordering and comparing version numbers
  • CompatibilityRule: Logic for determining version compatibility and breaking changes
  • VersionRange: Specification of acceptable version intervals with inclusion/exclusion criteria
  • PreReleaseMetadata: Support for development versions and release candidates

Main Data Flows and Transformations

  1. Version Parsing: Version strings → Structured version objects → Validation and normalization
  2. Version Comparison: Version pairs → Ordering relationships → Compatibility decisions
  3. Range Checking: Version + Requirements → Compatibility validation → Acceptance or rejection
  4. Version Ordering: Version collections → Sorted sequences → Latest/optimal version selection
  5. Compatibility Assessment: Version combinations → Rule evaluation → System configuration validation

External Dependencies and Interfaces

  • Protocol Module: Version comparison for protocol compatibility and migration decisions
  • Experiments Module: Version validation for experimental configuration consistency
  • Data Module: Data format versioning and backward compatibility management
  • Statistics Module: Statistical method versioning and result reproducibility

State Management Patterns

  • Immutable Version Objects: Version representations remain constant after creation
  • Cached Comparison Results: Performance optimization for repeated version comparisons
  • Version Registry Management: Centralized tracking of all system component versions
  • Validation State Tracking: Maintains validation results for version combinations

Core Algorithms or Business Logic Abstractions

  • Lexicographic Ordering: Standard version comparison algorithms following semantic versioning rules
  • Range Satisfaction: Algorithms for testing whether versions satisfy requirement specifications
  • Breaking Change Detection: Identification of version changes that break backward compatibility
  • Version Resolution: Algorithms for finding optimal version combinations given constraints
  • Precedence Rules: Handling of pre-release versions, build metadata, and special version cases
