Debugging

Goroutine Leak Detection and Fix in Production Go Services Writing automated test cases that detect goroutine leaks before deploying. Analyzing production runtime stack traces to locate orphaned channels. A Kubernetes pod abruptly restarts with exit code 137. The memory metrics dashboard shows a slow, perfectly linear staircase pattern stretching over three days. There are no panic logs in stdout, no database errors, and no abnormal CPU spikes. Just a slow, silent OOM (Out Of Memory) death. ...

Prerequisite: Familiarity with the concepts introduced in Part 2 — Context Engineering Codebase. Review it first if the terminology in this part is unfamiliar. Part 3 — The AI Bug Taxonomy: Hallucinations & Phantom APIs Answer-first: AI-generated code introduces a unique class of subtle defects distinct from traditional human coding errors. Understanding the AI Bug Taxonomy—encompassing Phantom API methods, Typosquatted Package Imports, Silent Type Coercions, and Logical Edge-Case Hallucinations—allows engineering teams to construct targeted AST static analysis filters that catch 95% of AI defects before code reaches production. ...
