Hello everyone. In this presentation, I will be discussing backtraces. I will discuss why backtraces are important, the implementation of backtraces in Ruby, why production of partial backtraces was slow in older versions of Ruby, and how it was fixed in Ruby 3. I will also discuss bugs that occurred as a result of the optimization, and how the bugs were fixed.
