AutoCron ⏰

Schedule Python tasks with one line of code. Works everywhere. Now with async support, task persistence, and safe mode!

AutoCron makes task scheduling painless—no cron syntax, no platform-specific setup. Just Python.

📊 Status: Active development | Small/medium production ready | Enterprise-ready in 3 weeks

---

🚀 Quick Start

Install:

pip install autocron-scheduler[all]  # With all features

Schedule a task:

from autocron import schedule

@schedule(every='5m')
def my_task():
    print("Running every 5 minutes!")

# Or use async!
@schedule(every='10m')
async def async_task():
    await fetch_data()

That's it. AutoCron handles the rest.

✨ What's New in v1.2.0

� Safe Mode (Security & Resource Control)

Run untrusted scripts safely with subprocess isolation and resource limits!

scheduler.add_task(
    name="untrusted_script",
    script="user_script.py",
    every="1h",
    safe_mode=True,        # Subprocess isolation
    max_memory_mb=256,     # Memory limit
    timeout=300            # Hard timeout
)

Features:

• ✅ Process isolation (failures don't affect parent)
• ✅ Memory limits (prevents OOM crashes)
• ✅ CPU limits (prevents system lockup - Unix)
• ✅ Timeout enforcement at OS level
• ✅ Output sanitization (10KB limit)

Perfect for:

• User-provided scripts (Unix/Linux/Mac with full resource limits)
• Multi-tenant environments (subprocess isolation on all platforms)
• Production systems with strict SLAs
• Processing untrusted data

Note: Windows currently supports subprocess isolation and timeout, but not memory/CPU limits. Full Windows Job Objects support coming soon.

�🔄 Async/Await Support

Schedule async functions natively—no extra configuration needed!

@schedule(every='5m')
async def fetch_api():
    async with aiohttp.ClientSession() as session:
        data = await session.get('https://api.example.com')
        return await data.json()

💾 Task Persistence

Save and restore tasks across system restarts. Your schedules survive reboots!

scheduler = AutoCron()
scheduler.add_task(name="backup", script="backup.py", every="1h")

# Save tasks to file
scheduler.save_tasks("my_tasks.yaml")

# Load them back after restart
scheduler.load_tasks("my_tasks.yaml")

📊 Visual Dashboard

Monitor task execution with beautiful terminal dashboards!

autocron dashboard          # View all tasks
autocron stats task_name    # Detailed analytics
autocron dashboard --live   # Real-time monitoring

💡 Examples

Simple Decorator

from autocron import schedule

@schedule(every='30m')
def fetch_data():
    # Runs every 30 minutes
    print("Fetching data...")

@schedule(cron='0 9 * * *')  # Every day at 9 AM
def daily_report():
    print("Generating report...")

Async Tasks (New in v1.2!)

import aiohttp
from autocron import schedule

@schedule(every='5m')
async def fetch_async():
    async with aiohttp.ClientSession() as session:
        async with session.get('https://api.example.com') as resp:
            return await resp.json()

@schedule(every='10m')
async def process_data():
    # Multiple async operations
    results = await asyncio.gather(
        fetch_data_1(),
        fetch_data_2(),
        fetch_data_3()
    )
    return results

Task Persistence (New in v1.2!)

from autocron import AutoCron

scheduler = AutoCron()

# Add tasks
scheduler.add_task(
    name="backup",
    script="backup.py",
    every='1h',
    retries=3
)

# Save to file (survives restarts!)
scheduler.save_tasks()  # Saves to ~/.autocron/tasks.yaml

# Later, after system restart...
scheduler.load_tasks()  # Restores all tasks
scheduler.start()

Visual Dashboard (New in v1.1!)

# View task summary
autocron dashboard

# Task details with analytics
autocron stats backup_task

# Live monitoring
autocron dashboard --live --refresh 2

Or in Python:

from autocron import show_dashboard, show_task

show_dashboard()  # Display all tasks
show_task("backup_task")  # Show specific task stats

Scheduler Class

from autocron import AutoCron

scheduler = AutoCron()

scheduler.add_task(
    name="backup",
    func=backup_database,
    every='1h',
    retries=3,
    notify='desktop'
)

scheduler.start()

With Retry & Timeout

@schedule(every='10m', retries=3, timeout=60)
def api_call():
    # Retries up to 3 times, max 60 seconds
    response = requests.get('https://api.example.com/data')
    return response.json()

Email Notifications

scheduler.add_task(
    name="critical_task",
    func=process_payments,
    cron='0 */4 * * *',  # Every 4 hours
    notify='email',
    email_config={
        'smtp_server': 'smtp.gmail.com',
        'smtp_port': 587,
        'from_email': 'YOUR_EMAIL@gmail.com',
        'to_email': 'ADMIN_EMAIL@gmail.com',
        'password': 'YOUR_APP_PASSWORD_HERE'
    }
)
