jdalton · jdalton · commit 03ec70b3b559 · 2026-03-10T16:29:38.000-04:00
- Fix division by zero in progress bars, spinners, and HTTP requests
- Add LRU cache eviction to git diff cache (prevent memory leak)
- Fix TOCTOU race in cache-with-ttl getOrFetch
- Improve clock skew detection in TTL cache
- Fix stable cache key generation in globs
- Fix memoizeAsync promise caching (don't cache failures)
- Add TTL validation in memoization
- Fix documentation errors (writeFileUtf8, PromiseQueue, getUserProfile)
- Align Node versions in CI workflow
- Pin dependency versions (libnpmexec, tar-stream)
- Add safety to parseInt in node.ts
- Fix bash loop patterns in git hooks
- Add note about fast-glob external dependency
- Add archive extraction documentation
- Clarify root import restriction reasoning

All 6328 tests passing.

-This approach keeps your bundle size small by only including the code you actually use.
+**Why subpath imports?** This library is designed for selective imports to keep bundle sizes minimal. Each subpath (like `/spinner` or `/fs`) is a separate export point defined in `package.json` exports field. The root import (`@socketsecurity/lib`) doesn't re-export all modules - you must use specific subpaths.
