How the timeout mechanism work in this project?

The GitHub issue seeks to understand how the timeout mechanism is implemented within the project. The user is requesting an explanation of its functionality, presumably regarding how timeouts are defined, handled, and triggered in various scenarios. Details or related code may need to be reviewed to provide clarity.

The timeout mechanism in llm-sandbox is configurable and enforced at both the session and code execution levels. Timeout settings are defined in the SessionConfig class, which includes default_timeout (default 60 seconds), execution_timeout, and session_timeout. If any of these are set to None, the corresponding operation will run indefinitely. The get_execution_timeout method returns the execution timeout, defaulting to default_timeout if not set SessionConfig code.

Timeout enforcement is handled by the TimeoutMixin class, which uses threading to run functions with a timeout. If the function exceeds the timeout, a SandboxTimeoutError is raised. For true cancellation (such as killing a stuck process), the mixin can trigger container-level termination if force_kill_on_timeout is True TimeoutMixin code.

At the session level, BaseSession uses a threading.Timer to enforce session timeouts and checks elapsed time against session_timeout, raising SandboxTimeoutError if exceeded. The run method in BaseSession uses _execute_with_timeout to enforce code execution timeouts and handles cleanup if a timeout occurs BaseSession code.

Timeout errors are always raised as SandboxTimeoutError, providing a consistent interface for handling these events. No recent changes to the timeout mechanism were found in the last month.

To reply, just mention @dosu.
