Happy to help out as well, since I'm quite interested in it! :) One case where I find this especially useful is for methods implemented in C because currently they get blamed on the file/line of the last Ruby frame on the stack, and sometimes that can get really confusing to follow (Mame mentioned https://bugs.ruby-lang.org/issues/18285 and when I was debugging this I had to break out backtracie to understand what was going on as the stack traces didn't make a lot of sense). This would also be very useful for profilers and other tools that work with stack traces :) ---------------------------------------- Feature #19117: Include the method owner in backtraces, not just the method name https://bugs.ruby-lang.org/issues/19117#change-100124 * Author: byroot (Jean Boussier) * Status: Open * Priority: Normal ---------------------------------------- ``` module Foo class Bar def inspect 1 + '1' end end end p Foo::Bar.new ``` This code produce the following backtrace: ``` /tmp/foo.rb:4:in `+': String can't be coerced into Integer (TypeError) from /tmp/foo.rb:4:in `inspect' from /tmp/foo.rb:9:in `p' from /tmp/foo.rb:9:in `
' ``` This works, but on large codebases and large backtraces the method name isn't always all that revealing, most of the time you need to open many of the locations listed in the backtrace to really understand what is going on. I propose that we also include the owner name: ``` /tmp/foo.rb:4:in `Integer#+': String can't be coerced into Integer (TypeError) from /tmp/foo.rb:4:in `Foo::Bar#inspect' from /tmp/foo.rb:9:in `Kernel#p' from /tmp/foo.rb:9:in `
' ``` I believe that in many case it would allow to much better understand the backtrace without having to jump back and forth between it and the source code. This is inspired by @ivoanjo 's `backtracie` gem: https://github.com/ivoanjo/backtracie -- https://bugs.ruby-lang.org/ Unsubscribe:
