Timeout Implementation Analysis for OCode Tools

Current Timeout Implementations

1. Tools with Network Operations

BashTool (bash_tool.py)

  • Timeout Support: ✅ Yes
  • Default: 30 seconds
  • Implementation: Uses asyncio.wait_for() with process.communicate()
  • Strengths:
    • Configurable timeout parameter
    • Proper cleanup with process termination escalation (SIGTERM → SIGKILL)
    • Process group management for better cleanup
  • Improvements Needed: None significant

CurlTool (curl_tool.py)

  • Timeout Support: ✅ Yes
  • Default: 30 seconds
  • Implementation: Uses aiohttp.ClientTimeout(total=timeout)
  • Strengths: Proper timeout configuration for HTTP requests
  • Improvements Needed: None significant

PingTool (ping_tool.py)

  • Timeout Support: ✅ Yes
  • Default: 5 seconds per ping
  • Implementation:
    • Individual ping timeout configured
    • Overall command timeout: count * (timeout + interval) + 5
  • Strengths: Well-designed timeout calculation
  • Improvements Needed: None significant

MCPTool (mcp_tool.py)

  • Timeout Support: ⚠️ Partial
  • Default: 30 seconds parameter exists
  • Implementation: Has timeout parameter but doesn't use it in simulated operations
  • Improvements Needed:
    • Implement actual timeout handling when connecting to MCP servers
    • Add timeout to tool calls and resource fetching

2. Tools with External Process Execution

TestTools (test_tools.py)

  • Timeout Support: ✅ Yes
  • Default: 300 seconds (5 minutes) for tests
  • Implementation: Uses asyncio.wait_for() with process.communicate()
  • Strengths: Reasonable default for test execution
  • Improvements Needed: None significant

ShellCommandTool (shell_tools.py)

  • Timeout Support: ✅ Yes
  • Default: 30 seconds
  • Implementation: Uses asyncio.wait_for() for both output capture and wait modes
  • Strengths: Handles both interactive and non-interactive modes
  • Improvements Needed: None significant

AgentTool (agent_tool.py)

  • Timeout Support: ⚠️ Partial
  • Default: 300 seconds parameter exists
  • Implementation: Has timeout parameter but only uses it in simulation
  • Improvements Needed:
    • Implement actual timeout handling for real agent operations
    • Add timeout enforcement for delegated tasks

3. Tools with I/O Operations

FileReadTool (file_tools.py)

  • Timeout Support: ❌ No
  • Risk: Could hang on network file systems or slow storage
  • Improvements Needed:
    • Add timeout parameter (default: 30 seconds)
    • Wrap file operations in asyncio.wait_for()

ProcessMonitorTool (process_tool.py)

  • Timeout Support: ❌ No
  • Risk: psutil operations could hang on unresponsive processes
  • Improvements Needed:
    • Add timeout parameter for process queries
    • Wrap psutil operations in asyncio.wait_for()

Summary of Findings

Well-Implemented Timeouts

  1. BashTool - Excellent timeout handling with proper cleanup
  2. CurlTool - Proper HTTP timeout configuration
  3. PingTool - Smart timeout calculation for network operations
  4. TestTools - Appropriate timeout for test execution
  5. ShellCommandTool - Good timeout handling for shell commands

Needs Improvement

  1. MCPTool - Has timeout parameter but doesn't use it effectively
  2. AgentTool - Timeout parameter exists but only used in simulation
  3. FileReadTool - No timeout protection for file I/O operations
  4. ProcessMonitorTool - No timeout for process queries

Recommended Actions

  1. Add timeout to file operations:

    • Wrap file reads/writes in asyncio.wait_for()
    • Default timeout: 30 seconds for local files, 60 for potential network files

  2. Enhance MCP and Agent tools:

    • Implement actual timeout enforcement when these tools perform real operations
    • Add timeout to all async operations

  3. Add timeout to process monitoring:

    • Wrap psutil operations in timeout blocks
    • Handle ProcessNotFoundError gracefully

  4. Standardize timeout defaults:

    • Network operations: 30 seconds
    • File operations: 30 seconds
    • Process operations: 10 seconds
    • Test execution: 300 seconds (5 minutes)

  5. Create a timeout utility:

    • Centralized timeout wrapper for common operations
    • Consistent error messages for timeout scenarios
