TigerBeetle's Hidden Bug: How Sophisticated Fuzzing Failed

2025-06-06

The TigerBeetle team discovered a bug in their query engine using Jepsen, surprisingly in a component previously fuzzed extensively by four separate fuzzers. The investigation revealed a blind spot in the fuzzer's input generation strategy, leaving certain query combinations uncovered. This stemmed from the fuzzer pre-registering queries during initialization—a simplification that inadvertently constrained input space diversity. By improving the fuzzer to generate more random inputs and perform more precise verification, the bug was successfully reproduced and fixed. This case highlights how even sophisticated fuzzing strategies can have blind spots, necessitating a combination of testing approaches for comprehensive software quality assurance.

Track Errors First: The Most Valuable Observability Signal

2025-06-05

This article argues that error tracking should be prioritized when building observability systems. The standard 'three pillars' model (logs, metrics, and traces) overlooks the most valuable signal: errors. Exceptions directly indicate failed assumptions in the code, offering more direct and valuable information than logs, metrics, or traces. The author advocates for deep error tracking, collecting full stack traces, local variables, request data, and user context, rather than simply counting errors. He criticizes the abstraction of errors as generic events and the trend of full-stack APM tools marginalizing error tracking, emphasizing that error tracking should be paramount, not an afterthought.
