Issue #21335 has been updated by tenderlovemaking (Aaron Patterson). mame (Yusuke Endoh) wrote in #note-2:
As the current behavior of the backtrace, if the receiver class is completely bound to the constant names, they are prefixed to the method names in the backtrace.
Ah, ok, I didn't know that. Thank you. I'm not sure if printing the address or the `ns_id` is better. Either works for me, but I'm not sure what would be most ergonomic. ---------------------------------------- Feature #21335: Namespaces should be present in the backtrace https://bugs.ruby-lang.org/issues/21335#change-113239 * Author: tenderlovemaking (Aaron Patterson) * Status: Open ---------------------------------------- Namespaces can call in to other name spaces. I think it might be helpful if namespace information is in the backtrace. For example: ```ruby File.binwrite "foo.rb", <<-eorb class Foo def self.test(ns1, ns2, count) if count == 0 puts caller else if count % 2 == 0 ns1::Foo.test(ns1, ns2, count - 1) else ns2::Foo.test(ns1, ns2, count - 1) end end end end eorb ns1 = Namespace.new ns1.load "foo.rb" ns2 = Namespace.new ns2.load "foo.rb" ns1::Foo.test(ns1, ns2, 10) ``` The output is like this: ``` See doc/namespace.md for known issues, etc. /Users/aaron/git/ruby/exe/ruby: warning: Namespace is experimental, and the behavior may change in the future! See doc/namespace.md for known issues, etc. /Users/aaron/git/ruby/foo.rb:9:in 'test' /Users/aaron/git/ruby/foo.rb:7:in 'test' /Users/aaron/git/ruby/foo.rb:9:in 'test' /Users/aaron/git/ruby/foo.rb:7:in 'test' /Users/aaron/git/ruby/foo.rb:9:in 'test' /Users/aaron/git/ruby/foo.rb:7:in 'test' /Users/aaron/git/ruby/foo.rb:9:in 'test' /Users/aaron/git/ruby/foo.rb:7:in 'test' /Users/aaron/git/ruby/foo.rb:9:in 'test' /Users/aaron/git/ruby/foo.rb:7:in 'test' ./test.rb:23:in '<main>' ``` `Foo.test` alternates between namespaces when calling a method, but you can't tell from the backtrace. I think we should include namespaces in the backtrace. -- https://bugs.ruby-lang.org/
