New submission from Abdulrahman Alabdulkareem <master3...@gmail.com>:
I get a random TypeError exception thrown whenever I interrupt/kill a sleeping parent thread from a child thread but ONLY if the python script was invoked by a shell script with an & argument to make it run in the background. (this is in vanilla python) This doesn't happen if invoked (1) in command line (2) in command line with & (3) in shell script (without &) Only in shell script with &. Here is the python script named psc.py https://pastebin.com/raw/KZQptCMr And here is the shell script named ssc.sh https://pastebin.com/raw/QQzs4Tpz that when ran will run the python script and cause the strange behaviour Here is the output I'm seeing: ------------------- parent looping child interrupting parent why would I ever catch a TypeError? Traceback (most recent call last): File "m.py", line 17, in <module> time.sleep(1) TypeError: 'int' object is not callable Here is the output I'm expecting: -------------------- parent looping child interrupting parent caught interruption raised from user or child thread :) Another unexpected behaviour might be that python suddenly hangs.
