[ruby-core:35236] [Ruby 1.9-Bug#3660] Trace events seem to be missing

Issue #3660 has been updated by Rocky Bernstein.


I don't think the problem is directly related to r24226. Instead, I think the call stack is one level one deeper than it had been previously due to the way "require" now works.

Around line 186 of lib/tracer.rb do the end:

if $0 == __FILE__
 ...
elsif caller.size <= 1 
  Tracer.on
end

But caller now reports: 

["<internal:lib/rubygems/custom_require>:29:in `require'", "<internal:lib/rubygems/custom_require>:29:in `require'"]

Changing the value in the "elsif" test from 1 to 2 will start showing trace output. However one may
want to do a more rigorous test and match on values in caller looking for <internal:lib/rubygems/custom_require> or something like that.
