fix: align caret includePrerelease lower bounds by wayyoungboy · Pull Request #872 · npm/node-semver (original) (raw)

Summary

• keep exact caret lower bounds at the release version when includePrerelease is enabled
• add regression fixtures for ^0.0.3 and ^0.2.3 prerelease versions matching the existing ^1.0.0 behavior

Root Cause

For exact 0.x caret ranges without an explicit prerelease, replaceCaret appended -0 to the lower bound when includePrerelease was enabled. That turned ^0.0.3 into >=0.0.3-0 <0.0.4-0, allowing 0.0.3-alpha while exact 1.x caret ranges kept >=1.2.3 and rejected 1.2.3-alpha.

Test Plan

• RED: Node assert script confirmed satisfies('0.0.3-alpha', '^0.0.3', { includePrerelease: true }) returned true before the fix
• GREEN: Node assert script for 0.0.3-alpha, 0.2.3-alpha, and 1.2.3-alpha all returning false
• node fixture script covering range include/exclude fixtures: 121 include and 98 exclude cases
• broader node range verification script: 1348 checks across range parsing, intersects, outside/gtr/ltr, min/max satisfying, and toComparators
• git diff --check HEAD^ HEAD
