Killable threads in Python!

Project description

Build Status

kthread

Killable threads in Python!

Purpose

The built-in threading.Thread class offers no simple solution to terminate a running thread. kthread.KThread inherits threading.Thread and supplies methods named exit(), kill(), and terminate() that serve the same purpose: attempt to stop a thread if it's running.

How it works

KThread leverages the CPython API to raise a SystemExit exception on a given thread. Assuming that the thread is not blocked by an operating system call (such as sleep, accept, or recv), the thread will forcefully quit.

TERMINATING THREADS MAY INTRODUCE INSTABILITY OR OTHER UNDESIRABLE EFFECTS IN YOUR PROGRAMS. THIS SOFTWARE COMES WITH ABSOLUTELY NO WARRANTY. THE MUNSHI GROUP CANNOT BE HELD LIABLE FOR ANY DAMAGES, LOSSES, OR EXPENSES INCURRED BY YOU OR YOUR ORGANIZATION WHILE USING THIS SOFTWARE.

>>>         sys.stdout.flush()
