How to Bisect a Problem in the Perl 5 Debugger

Bisection and the Perl 5 Core Distribution

Bisection is a developer's technique used to locate the point in a series of commits to a repository where the behavior of an application changed. While this change could be a change for the better -- "When did this feature start accidentally working?" -- the change being sought is usually a change for the worse: "When did this feature stop working correctly?".

The following are comments I solicited from a veteran Perl user who has held positions at the "director of technology" level, spoken at Perl conferences and contributed to major CPAN projects. I do not necessarily agree with these comments but believe they are worthy of consideration at the 2017 Perl 5 Core Hackathon and in other contexts. -- jkeenan

I spend a lot of time thinking about this and in the end it comes down to two general categories of things. The first one is obvious stuff about how we communicate the worth of Perl to technology consumers, and support our existing user base. The second (and in my mind the most important one) has to

I have not built or used any of these, so your mileage may vary.

From https://github.com/Microsoft/xlang ...

"The xlang project enables developers to take existing shared libraries, 
implemented in one programming language and make that library's APIs 
available to client code using a different programming language. Thus 
the name "xlang," for cross-language.

"Additionally, the xlang toolset will be available on multiple operating 
systems. This means that if your shared library is portable to various 
operating systems, then you can use the xlang tooling to make that shared
