Pinpointing Changes with Bisection

This is a talk about git bisect and how it can be used on the Perl core, inspired by my node How to Bisect Perl on PerlMonks.

Watch the talk here! (in German)

This talk was given (in German) at the 23rd German Perl/Raku Workshop 2021 https://act.yapc.eu/gpw2021/talk/7761

This repository contains all the material for the talk:

• The recording of the talk and the player in the docs directory, served by GitHub at https://haukex.github.io/bisectalk

• The cpanfile that lists the dependencies for the repository, which you can install via cpanm --installdeps .; Perl v5.28 or better is also required

• The slide viewer and slides in slide.pl and slides.inc.pl, the latter also includes the "script" used for the commandline demos

• The demo script whose history I bisect is math.pl

• Scripts used for bisection in the bisect directory, including runner.sh for the simpler bash-based bisection runner, and viz.pl for the Perl-based visualization

• Examples of binary search in binsearch.pl and binsearch_viz.pl, plus some code to fetch the list I search in my demo in getlist.pl

• A few more examples used in the talk are in the examples directory

• Tests for several of the above scripts in the t directory (run via e.g. prove)
