Premature Event Loop Closure Causes Timeouts

[JoshuaAIHAHA]

This report details the resolution of timeout errors encountered during process execution.

Root Cause:

The root cause of the timeout errors was identified as premature event loop closure. This led to processes being terminated before they could complete, resulting in messages such as "timed out: bash has not returned in 120.0 seconds and must be restarted".

Solution:

To address this issue, the stop() method was modified to ensure proper asynchronous handling and process termination:

async def stop(self):
    if self._process.returncode is None:
        self._process.terminate()
        await self._process.wait()  # Ensure process termination

This change ensures that the event loop remains active until the process has fully terminated.

Testing and Validation:

Extensive testing was conducted to validate the effectiveness of the fix. Various scenarios were tested, including:

Background processes
Multiple parallel processes
Mixed stdout/stderr operations
Rapid successive commands
Complex process management
All tests were successful, with no timeout errors observed, regardless of output size or process complexity.

This solution effectively resolves the timeout issues by ensuring proper event loop management during process execution.
