panicscan

panicscan is a sophisticated static analysis tool for the Go programming language. Its primary purpose is to detect a wide range of potential runtime panics by analyzing Go source code, helping developers write more robust and reliable applications.

Features

• Comprehensive Panic Detection: Identifies numerous panic categories including:
  • Explicit panic() calls
  • Integer division by zero
  • Nil pointer dereferences
  • Writes to nil maps and sends to nil channels
  • Operations on closed channels
  • Out-of-bounds access on fixed-size arrays
  • Calls to nil function variables
• Intelligent Analysis: Utilizes data flow analysis and state tracking to understand variable states (nil, non-nil, closed), significantly reducing false positives.
• Concurrency Aware: Intelligently handles common concurrency patterns to avoid flagging safe, idiomatic code.
• Project-Wide Scanning: Correctly loads and analyzes entire Go projects, including those with multiple packages and complex dependencies, supporting the ./... pattern.
• Configurable: Allows excluding specific directories from the scan.
