📝 Info: Subtle behavioral change: cached rate-limit warnings no longer re-emitted on headerless responses
The old code pre-initialized limit_snapshot, remaining_snapshot, reset_snapshot to None, then always entered the lock block — even when no rate-limit headers were present in the response. Inside the lock, it would read back the previously cached values from _rate_limit_info and potentially re-log a rate-limit warning based on stale data.
The new early return at line 166-167 skips this entirely when all three parsed headers are None. This means a response without rate-limit headers will no longer trigger a re-check of cached values. In practice this is a correct optimization — any warning would have already been logged by the response that originally provided those headers — but it is a semantic change worth noting in case the repeated-warning behavior was intentionally relied upon (e.g., for monitoring dashboards that count warning frequency).

This improves the code health of api_client.py by adding a fast path exit in _parse_rate_limit_headers for the common case where responses don't include any rate limit headers, removing redundant assignments to None and skipping a thread lock acquisition.

🎯 What: The code health issue addressed
Refactored
api_client.pyinside_parse_rate_limit_headersto add an early return fast-path ifnew_limit,new_remaining, andnew_resetare allNone. Also removed redundant variable initialization.💡 Why: How this improves maintainability
If an API response does not include rate limit headers (which is common), the code previously created variables, assigned
Noneto snapshots, and acquired a lock only to realize there is nothing to update. Adding the early exit greatly improves the readability of the lock critical section, removes unnecessary nesting of logic for a no-op state, and provides a small performance gain.✅ Verification: How you confirmed the change is safe
Tests inside
tests/test_rate_limit.pyandtests/test_performance_regression.pywere run passing flawlessly usinguv run pytest tests/, and pre-commit checks formatted and verified syntax health successfully. Also verified with benchmarks which demonstrated a speed up insidetest_rate_limit_parsing_empty_headers_performance.✨ Result: The improvement achieved
Reduced nesting, eliminated redundant snapshot initializations, avoided useless lock acquisitions, and achieved a performance boost for empty-header responses without changing functionality.
