Why does this not run into an infinite loop?
Tag : python , By : Malikul

Hope this helps It does not "run foo3 again", it runs the foo3.py script again. The first time foo3.py was running was to produce the module __main__, the second time to produce the module foo3.py.
The behaviour is in fact (almost) as if you had a file named __main__.py and another named foo3.py both with these exact same content and you then run python __main__.py. This is what is happening.
import sys

def functionA():
    print("a1")

    if 'foo3' in sys.modules:
        del sys.modules['foo3']

    from foo3 import functionB
    print("a2")
    functionB()
    print("a3")

def functionB():
    print("b")

print("t1")
print("m1")
functionA()
print("m2")
print("t2")
  [....]
  File ".../foo3.py", line 7, in functionA
    from foo3 import functionB
  File ".../foo3.py", line 17, in <module>
    functionA()
  File ".../foo3.py", line 7, in functionA
    from foo3 import functionB
RuntimeError: maximum recursion depth exceeded while calling a Python object

Infinite Loop : Determining and breaking out of Infinite loop


Tag : algorithm , By : Ed.

fixed the issue. Will look into that further There is no general case algorithm that can determine if a program is in an infinite loop or not for every turing complete language, this is basically the Halting Problem.
The idea of proving it is simple:

How to create infinite loop, call method in it on if(condition=true), and continue infinite loop after execution of meth

like below fixes the issue The code will keep running indefinitely due to your while(true) clause, regardless of what value x has (since x only dictates when RunFrame() gets called).
The only issue I see is that RunFrame throws some sort of exception or aborts the program. You can try it like below:
while(true)
{
   if(x==true)
   { 
       try
       {
           RunFrame(); 
       }
       catch(Exception e)
       {
           e.printStackTrace();
       }
   }
}

Executing two infinite loops together. 1 while loop for multithreaded server and other infinite loop for GUI

it should still fix some issue You need to start another thread for the main loop of the socket server. That will allow the main thread to run the UI.
Just replace the loop with this code:
def server_thread(s):
   while True:
      conn, addr = s.accept()
      start_new_thread(clientthread,(conn,))

start_new_thread(server_thread,(s,))

Difference between 'busy-wait' infinite loop and condition validation infinite loop

it helps some times Because waiting on a condition variable is a non-busy wait. The CPU isn't actually doing any work. Instead, the thread is idle, waiting on a signal. The thread is not given any CPU resources until the condition is signaled.
When the condition is signaled, the thread becomes eligible again, and the scheduler can once again allocate CPU resources to it.

The proper Python exception to break out of an infinite loop (that shouldnt be infinite)

it should still fix some issue The only way this wouldn't occur is if do_stuff never returns false.
If that is the case create a custom exception. I usually create a MiscException (along with more specific exceptions)
