⚡ Bolt: Optimize logging overhead and fix validation syntax by abhimehro · Pull Request #426 · abhimehro/ctrld-sync

abhimehro · 2026-02-25T14:59:46Z

This PR fixes a critical SyntaxError in main.py that prevented the application from running, and implements a performance optimization for logging.

Changes:

Fix SyntaxError: Corrected broken code in validate_folder_data (lines ~1141) where a loop over rules was malformed (rgi"rules"1) and unindented. Also ensured the function returns True on success.
Performance Optimization: Wrapped multiple log.debug calls in if log.isEnabledFor(logging.DEBUG):.
- Why: Calls like log.debug(f"... {sanitize_for_log(x)} ...") evaluate the f-string and run sanitize_for_log (which uses regex) before passing the result to the logger, even if debug logging is disabled.
- Impact: Reduces CPU usage and lock contention in hot paths (e.g., _gh_get cache hits, _retry_request, save_disk_cache).

Verification:

Ran python -m py_compile main.py to verify syntax.
Ran python -m pytest tests/ and python -m pytest test_main.py. All 169 tests passed.

- Fix SyntaxError in `validate_folder_data` where loop syntax and indentation were broken. - Implement lazy logging optimization: wrap expensive `log.debug` calls (using f-strings or `sanitize_for_log`) with `if log.isEnabledFor(logging.DEBUG):`. - This reduces CPU overhead on hot paths (e.g., caching, retries) when debug logging is disabled. - Fixes `AssertionError` in tests caused by missing return in `validate_folder_data`.

Summary of Changes

Hello @abhimehro, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses a critical SyntaxError that was causing the application to fail and introduces a performance optimization to reduce CPU usage and lock contention by conditionally executing debug logging statements. The changes improve the application's stability and efficiency.

Highlights

SyntaxError Fix: Corrected a SyntaxError in validate_folder_data that was preventing the application from running, ensuring the function returns True on success.
Performance Optimization: Implemented a performance optimization by wrapping log.debug calls in if log.isEnabledFor(logging.DEBUG): to avoid unnecessary f-string evaluation and sanitize_for_log calls when debug logging is disabled.

Changelog

main.py
- Fixed SyntaxError in validate_folder_data.
- Implemented performance optimization for logging.

Code Review

This pull request delivers a critical fix for a SyntaxError in validate_folder_data that was preventing the application from running, and also correctly adds a missing return True statement. The performance optimizations for logging are well-implemented, correctly using log.isEnabledFor(logging.DEBUG) to avoid expensive argument evaluation for debug messages. This is a great improvement for performance in hot paths. I've added one suggestion to refactor some duplicated code in the retry logic to further improve maintainability.

gemini-code-assist · 2026-02-25T15:06:06Z

main.py

                if hasattr(e, "response") and e.response is not None:
-                    log.debug(f"Response content: {sanitize_for_log(e.response.text)}")
+                    if log.isEnabledFor(logging.DEBUG):
+                        log.debug(f"Response content: {sanitize_for_log(e.response.text)}")


This block of code for logging the response content is a duplicate of the logic on lines 1271-1275. To improve maintainability and adhere to the DRY (Don't Repeat Yourself) principle, consider extracting this logic into a small helper function.

For example:

def _log_debug_response_text(e: httpx.HTTPStatusError): """Safely logs response text if available and debug logging is enabled.""" if log.isEnabledFor(logging.DEBUG) and hasattr(e, 'response') and e.response is not None: log.debug(f"Response content: {sanitize_for_log(e.response.text)}")

You could then call this helper function here and in the block for non-retriable 4xx errors.
