Concurrency Bug Pattern Analysis

A Concurrency Bug Pattern Analysis is a bug pattern analysis that identifies recurring thread synchronization errors and concurrent execution defects in multi-threaded software systems.

• AKA: Thread Bug Pattern Analysis, Parallel Bug Pattern Analysis, Synchronization Bug Pattern Analysis, Race Condition Pattern Analysis.
• Context:
  • It can typically detect data race patterns in shared memory access.
  • It can typically identify deadlock patterns through lock dependency analysis.
  • It can often uncover concurrency-related root cause patterns in thread interaction.
  • It can often produce thread-safety code enhancement suggestions for synchronization improvement.
  • It can range from being a Static Concurrency Bug Pattern Analysis to being a Dynamic Concurrency Bug Pattern Analysis, depending on its analysis approach.
  • It can range from being a Lock-Based Concurrency Bug Pattern Analysis to being a Lock-Free Concurrency Bug Pattern Analysis, depending on its synchronization model.
  • It can range from being a Two-Thread Concurrency Bug Pattern Analysis to being a Many-Thread Concurrency Bug Pattern Analysis, depending on its thread complexity.
  • It can range from being a Deterministic Concurrency Bug Pattern Analysis to being a Non-Deterministic Concurrency Bug Pattern Analysis, depending on its execution predictability.
  • It can employ thread analysis tools for execution trace analysis.
  • It can support concurrency-aware preventive code maintenance processes.
  • Domain-Specific Bug Pattern Analysises (siblings), such as:
    • Security Bug Pattern Analysis for vulnerability patterns.
    • Memory Bug Pattern Analysis for memory error patterns.
    • Performance Bug Pattern Analysis for efficiency patterns.
    • API Misuse Pattern Analysis for interface error patterns.
  • ...
• Examples:
  • Synchronization Concurrency Bug Pattern Analysises, such as:
    • Deadlock Pattern Analysis for circular wait conditions.
    • Livelock Pattern Analysis for infinite retry loops.
    • Starvation Pattern Analysis for thread scheduling issues.
  • Data Concurrency Bug Pattern Analysises, such as:
    • Race Condition Pattern Analysis for unprotected shared data.
    • Data Race Pattern Analysis for concurrent memory access.
    • Atomicity Violation Pattern Analysis for non-atomic operations.
  • ...
• Counter-Examples:
  • Sequential Bug Pattern Analysis, which analyzes single-threaded execution rather than concurrent execution.
  • Performance Bottleneck Analysis, which identifies speed issues rather than concurrency defects.
  • Memory Bug Pattern Analysis, which focuses on memory errors rather than thread synchronization.
