🔍 MemoryGuard

Like Lego for your Code - Modular Python Memory Monitoring & Valgrind Integration

Drop-in memory monitoring for any Python project. Track memory usage, detect leaks, profile tools, and integrate with Valgrind - all with minimal overhead.

✨ Features

• 🎯 Zero Config - Works out of the box
• 📊 Real-time Monitoring - Live memory tracking
• 🔍 Leak Detection - Automatic leak identification
• 🛠️ Tool Profiling - Per-function memory analysis
• 📺 Live Dashboard - Beautiful terminal UI (optional)
• 🔧 Valgrind Integration - Deep C-extension analysis
• 🚀 CI/CD Ready - GitHub Actions integration
• 🧩 Modular - Use only what you need

🚀 Quick Start

pip install memoryguard

Basic Usage

from memoryguard import MemoryGuard, track_memory

# Initialize
guard = MemoryGuard(threshold_mb=500)

# Track any function
@track_memory("heavy_computation", guard)
def heavy_computation():
    return sum(i**2 for i in range(1000000))

result = heavy_computation()

# Check memory manually
alert = guard.check_memory("after_computation")
if alert:
    print(f"⚠️  {alert.message}")

Context Manager

from memoryguard import memory_context

with memory_context("database_query", guard):
    # Your code here
    large_dataset = fetch_data()
    process(large_dataset)
# Memory automatically tracked

Live Dashboard

from memoryguard import MemoryDashboard

dashboard = MemoryDashboard(guard)

with dashboard.live_display():
    # Your long-running operation
    run_big_analysis()

🧩 Integration Patterns

Pattern 1: Decorator (Simplest)

from memoryguard import track_memory, get_memory_guard

guard = get_memory_guard(threshold_mb=1000)

@track_memory("my_function", guard)
def my_function():
    pass

Pattern 2: Class Inheritance (For Tools)

from memoryguard import MemoryInstrumentedTool

class MyScanner(MemoryInstrumentedTool):
    tool_name = "myscanner"
    
    def scan(self, target):
        with self.memory_context(target):
            return self.do_scan(target)

Pattern 3: Orchestrator (For Workflows)

from memoryguard import MemoryAwareOrchestrator

orchestrator = MemoryAwareOrchestrator(max_memory_mb=2000)
orchestrator.register_tool(my_tool)

result = await orchestrator.execute_with_memory_control(
    "my_tool", target, my_tool.scan(target)
)

📊 Dashboard

If you have rich installed:

pip install memoryguard[dashboard]

Live Dashboard Preview

Live memory monitoring with top processes, RSS/VMS usage, and memory percentage

from memoryguard import MemoryDashboard

dashboard = MemoryDashboard(guard)

# Simple text output
print(dashboard.get_simple_display())
# [Memory: 456.3MB | Status: OK | Alerts: 0]

# Or live display
with dashboard.live_display():
    run_analysis()

Shows:

• Live memory graph (sparkline)
• RSS/VMS usage
• Recent alerts
• Tool breakdown
• Progress bars

🔧 Valgrind Integration

For C-extension analysis:

from memoryguard import ValgrindWrapper

wrapper = ValgrindWrapper()

if wrapper.available:
    result = wrapper.check_python_module(
        "my_c_extension",
        timeout=300
    )
    print(result['valgrind_log'])

🚀 CI/CD Integration

GitHub Actions

name: Memory Check

on: [push, pull_request]

jobs:
  memory-test:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v3
    - uses: actions/setup-python@v4
      with:
        python-version: '3.11'
    
    - name: Install
      run: pip install memoryguard
    
    - name: Run with Memory Tracking
      run: |
        python -c "
        from memoryguard import MemoryGuard
        guard = MemoryGuard()
        # ... your code ...
        guard.generate_report('memory-report.json')
        "
    
    - name: Upload Report
      uses: actions/upload-artifact@v3
      with:
        name: memory-report
        path: memory-report.json

📈 Advanced Usage

Memory-Efficient Batch Processing

from memoryguard import memory_efficient_batch

async def process_targets(targets):
    async def scan_batch(batch):
        return [await scan(t) for t in batch]
    
    return await memory_efficient_batch(
        targets,
        scan_batch,
        batch_size=10
    )

Leak Detection

# Reset baseline
guard.reset_baseline()

# Run your code
suspected_leaky_function()

# Check for leaks
leak_report = guard.detect_leaks("my_function")
if leak_report:
    print(f"Leaked: {leak_report['total_leaked_mb']}MB")

Force Garbage Collection

stats = guard.force_gc()
print(f"Freed {stats['memory_freed_mb']:.1f}MB")
print(f"Collected {stats['objects_collected']} objects")

⚙️ Configuration

guard = MemoryGuard(
    threshold_mb=500,           # Warning threshold
    critical_threshold_mb=1000,  # Critical threshold  
    check_interval=30,           # Background check interval (seconds)
    enable_snapshots=True,       # Store history
    log_dir="~/.memoryguard/logs"  # Report location
)
