Re: Canceling/interrupting raw_input

[Daniel Cer]

Just a little bit of a follow up on this...
If you use win32api.TerminateProcess() instead of sys.exit(), everything 
works as it should on Windows. That is, there is no longer a need to hit 
'enter' one last time in order to get "inputLoop" to terminate.

So, modifying the sample code I posted earlier, the new Win32 specific 
code would be the following:

import thread
import time
import sys
import win32api
def inputLoop():
     while 1:
             input_string = raw_input("Type something: ")
             print "You entered: ", input_string
thread.start_new_thread(inputLoop, () )
time.sleep(3)
print "\nTime's up exiting...."
win32api.TerminateProcess(-1, 0)

For what it's worth, this looks like a Windows specific problem.
The code below seems to work as expected on a Linux box. That is, 
everything terminates, including the "inputLoop", after sys.exit() is 
called, without the user needing to press 'enter' one last time.

However, if I try to run the code on Windows XP, it exhibits the exact 
same behavior you described.

#!/usr/bin/python
import thread
import time
import sys
def inputLoop():
     while 1:
             input_string = raw_input("Type something: ")
             print "You entered: ", input_string
thread.start_new_thread(inputLoop, () )
time.sleep(15)
sys.exit()

I'm working on a MUD server and I have a thread that gets keyboard 
input so that you can enter commands from the command line while it's 
in its main server loop.  Everything works fine except that if a 
player enters the 'shutdown' command, everything shuts down, but the 
input thread is still sitting waiting for enter to be pressed for 
raw_input.  After enter is pressed, it exits back to the command 
prompt as it should.

I'm wondering if there's a way that I can make the thread stop waiting 
for input.  Even sys.exit() still leaves it waiting.  It's not a big 
deal, but it bugs me.

Any ideas?  Should I be using something other than raw_input?  I'm on 
Windows2000 and running this from the DOS prompt.  I'm using Python 2.4.
