In principle pure Python code should have no memory leaks - if there are, they're on Python itself.
Maybe this is an allocation problem, not an actual leak; if you can write a program that reproduces the problem, post a bug at http://bugs.python.org

I would need to make some high-reliability software running on Linux in an embedded system. Performance (or lack of it) is not an issue, reliability is. The piece of software is rather simple, probably a few hundred lines of code in Python. There is a need to interact with network using the socket module, and then probably a need to do something hardware- related which will get its own driver written in C.

Hey guys (thus begins a book of a post :), I'm in the process of writing a commercial VoIP call monitoring and recording application suite in python and pyrex. Basically, this software sits in a VoIP callcenter-type environment (complete with agent phones and VoIP servers), sniffs voice data off of the network, and allows users to listen into calls. It can record calls as well. The project is about a year and 3 months in the making and...

No response to my last message, so I'll try a different tack... Does anyone know of, or even better, has anyone here written a C++ application for Mac/Windows that allows users to run Python scripts from within the app? Not just once, but many times in a single session, and without leaking memory. Preferably an open source app so I can see how it's done. Our app (http://golly.sourceforge.net/) currently uses calls like these every...

I have a python code which is running on a huge data set. After starting the program the computer becomes unstable and gets very diffucult to even open konsole to kill that process. What I am assuming is that I am running out of memory. What should I do to make sure that my code runs fine without becoming unstable. How should I address the memory leak problem if any ? I have a gig of RAM. Every help is appreciated.

Hi folks, Quick Synopsis: A test script demonstrates a memory leak when I use pythonic extensions of my builtin types, but if I use the builtin types themselves there is no memory leak. If you are interested in how builtin/pure-python inheritance interacts

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
