08:00 AM Ruby Bug #22058: {Method,InstanceMethod}#super_method doesn't work correctly for refined method with refinements for method active in the caller's scope

It took a lot of work, but I was able to fix `Method#super_method` to return the same method that `super` would call when refinements are used: https://github.com/ruby/ruby/pull/16997
I'm not positive it handles every case correctly, ... jeremyevans0 (Jeremy Evans)

08:04 PM Ruby Bug #22058: {Method,InstanceMethod}#super_method doesn't work correctly for refined method with refinements for method active in the caller's scope

@shugo Thank you, I think I finally understand. After the first refinement method is called, the caller's scope no longer matters, because each `super` call site considers the refinements in effect at that `super` call site. You cannot u... jeremyevans0 (Jeremy Evans)

@mame thank you for clarifying. I apologize for implicating you :)

03:52 AM Ruby Bug #22070: `Thread.each_caller_location(1, 1)` segfaults when called from a cfunc

Thank you for the report. I can confirm the issue. Note that it only affects Ruby 4.0. Ruby 3.4 is not affected, and Ruby 3.3 doesn't support arguments to `Thread.each_caller_location`. I traced the cause of the bug to commit:10767283dd0... jeremyevans0 (Jeremy Evans)

04:33 PM Ruby Bug #22071 (Closed): super in method in module that is refined results in NoMethodError

We currently support refinements of modules, even though doc/syntax/refinements.rdoc and https://github.com/ruby/ruby/wiki/Refinements-Spec imply that we would not respect refinements of included or prepended modules and would only respe... jeremyevans0 (Jeremy Evans)

02:14 AM Ruby Bug #22058 (Assigned): {Method,InstanceMethod}#super_method doesn't work correctly for refined method with refinements for method active in the caller's scope

I've found that Method#super_method and InstanceMethod#super_method do not work correctly in some cases for refined methods. At the least, there is a definite bug, which is that #super_method inside a scope with a refinement activated f... jeremyevans0 (Jeremy Evans)
