Uninstall tool not working.
Hi, I was trying to uninstall version 3.10.7 of python but I've encountered problems with the uninstall tool. I open the python setup program, click on the uninstall button but it doesn't even start deleting python even though it says that the process has finished. Feel free to ask for more details in case I didn't explain it correctly. Thanks in advance for your help. -- https://mail.python.org/mailman/listinfo/python-list
[issue41606] multiprocessing.Event.wait hangs when interrupted by signal that sets the event
New submission from Salvatore Ingala : According to the docs, multiprocessing.Event is a clone of threading.Event. Yet, there is a strange behavior that is observed only on multiprocessing.Event. If an event.wait() is interrupted by a SIGINT and the signal handler sets the event, then the call to event.set() hangs if event is an instance of multiprocessing.Event, in what looks like a deadlock; instead, it works as expected if it's an instance of threading.Event. See the file attached for a reproduction. It seems to have been so for a long time, see: https://stackoverflow.com/questions/24422154/multiprocessing-event-wait-hangs-when-interrupted-by-a-signal/30831867 -- files: event-test.py messages: 375745 nosy: salvatore.ingala priority: normal severity: normal status: open title: multiprocessing.Event.wait hangs when interrupted by signal that sets the event type: behavior versions: Python 3.8 Added file: https://bugs.python.org/file49419/event-test.py ___ Python tracker <https://bugs.python.org/issue41606> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Valgrind and pexpect
Hi,
I'm using the pexpect module to spawn some processes in a testing

valgrind python and get memory leaks from the spawned children
(assuming that python doesn't leak :)).
Here's a simple testcase:
===
leak.c:
===
#include stdlib.h
#include stdio.h
int main()
{
int *i = (int *) malloc(sizeof(int));
*i = 7;
printf(*i=%d\n, *i);
return 0;
}
===
leak.py:
===
import pexpect
import sys
child = pexpect.spawn('./leak')
child.expect('\*i=');
print 'Done'
===
Valgrind command:
===
valgrind --leak-check=full --trace-children=yes --tool=memcheck
--suppressions=valgrind-python.supp python ./leak.py

and I have uncommented the parts related to PyObject_Free and
PyObject_Realloc, as explained there.
So, does anyone know what the correct way to do this is?
Thanks in advance,
Salvarore.

Re: Watch log
Thinker ha scritto: What you want is something like 'tail -f' in linux. If you look into it's source code, you will find it check file periodically. When a read() reach the end of the file, read() will return a empty string. You can try to read data from the file periodically after a EOF. I think it is what you want.

Re: Forum written in Python?
Hello, Look at Karrigell, it includes the base of a forum and a blog in is demo Karrigell is a wonderfull pythonic framework. It's simple and efficient. Thanks his author Regards slav0nic a écrit : Karlo Lozovina ÐÉÛÅÔ: Are there any forum or bulletin board systems written entirely in Python? I got sick of PhpBB, mostly because I can't tweak and fiddle with the code, since I really don't like PHP and don't know it that well. I thought of writting my own simple forum software, but if there are existing projects out there, I wouldn't mind contributing.
