Bug Description

SimpleBox.shutdown() calls self._box.shutdown(), but the underlying Rust Box object only exposes stop(), not shutdown(). This causes an AttributeError at runtime.

Reproduction

import asyncio, boxlite

async def main():
    box = boxlite.SimpleBox(image="python:slim")
    await box.start()
    try:
        result = await box.exec("echo", "hello")
        print(result.stdout)
    finally:
        await box.shutdown()

asyncio.run(main())

Expected: Box shuts down gracefully.

Actual:

AttributeError: 'builtins.Box' object has no attribute 'shutdown'

Root Cause

# simplebox.py
def shutdown(self):
    self._box.shutdown()  # ← Box only has stop(), not shutdown()

The underlying Box object exposes: copy_in, copy_out, exec, id, info, metrics, name, start, stop — no shutdown.

Note

• SimpleBox also does NOT have a stop() method, so there is no working explicit cleanup method at all
• The async with context manager presumably works (calls something internally), but the manual lifecycle path is broken
• shutdown() is also a sync method but the docs show await box.shutdown() (async call on sync method)

Fix

Either:

1. Change shutdown() to call self._box.stop(), or
2. Expose stop() on SimpleBox as well

Environment

• boxlite 0.5.10
• Python 3.12.3
• macOS 15.6 (Apple Silicon)
