Python time limit library, using event loop to schedule job.

Resources:

Install

pip install timelimiter

Usage

1. Extend TimeoutHandler with timeout expressed in seconds。Override _run method。MySQLTimeoutHandler for example.

from timelimiter.timeout_handler import TimeoutHandler, TimeoutHandlerFactory


class MySQLTimeoutHandler(TimeoutHandler):
    timeout = 0.5

    def __init__(self):
        super(MySQLTimeoutHandler, self).__init__()
        # Some way to get MySQL thread id
        self.thread_id = 1

    def _run(self):
        # Kill MySQL connection
        print(self.thread_id)


class MySQLTimeoutHandlerFactory(TimeoutHandlerFactory):
    def create_handler(self) -> TimeoutHandler:
        return MySQLTimeoutHandler()

2. Use TimeLimiter to wrap the function。

from timelimiter.event_loop import start_loop
from timelimiter.time_limiter import TimeLimiter

start_loop()
factory = MySQLTimeoutHandlerFactory()

@TimeLimiter(factory)
def foo():
    # Do something
    ...
