[L2Ork-dev] L2Ork-dev Digest, Vol 89, Issue 63

Wed Mar 24 00:31:09 EDT 2021

Respected Sir, I want to work on ‘Web app UI cleanup’ project I run the code on my machine by following the documentation given for the above project. 
But there are some errors in console.

The app is not even working. I didn’t get any clue how to start.
Please direct me so that I can move further with the project.

I'm Meet Agrawal from Visvesvaraya National Institute of Technology
I'm looking forward to work on the project -
  Use ref-counting to handle object lifetimes
As far as I've considered the project it relates to programming crashing
due to some dereferencing of pointers whose memory access on heap has
already been lost
I've recently worked out on a project for Garbage collection routine in C++
Using the mark-sweep algorithm we can actually create up a table where we
trace back a pointer to its parent and if the parent is set deactive in the
program we free that further allocated space and set the pointer to null

I want to get a further view over what the project exactly wants an
implementation for.
Thank You

Hello Meet Agrawal,

Welcome!

Yes, the basic problem is that of accessing memory which has already been freed.

However, Purr Data is a realtime program. That means we measure
worst-case performance
times of deterministic behavior. Any solution to the problem must take
this into account.
