Bug #4352: [patch] Fix eval(s, b) backtrace; make eval(s, b) consistent with eval(s)

Author: James M. Lawrence
Status: Assigned
Priority: Normal

Target version: 1.9.x
ruby -v: ruby 1.9.3dev (2011-02-01 trunk 30751) [i386-darwin9.8.0]


=begin
 def ex_message
   begin
     yield
   rescue => e
     p e.message
   end
 end
 
 ex_message { eval('raise') }
 ex_message { eval('raise', binding) }
 
 eval('def f ; end')
 p method(:f).source_location
 eval('def g ; end', binding)
 p method(:g).source_location
 ----
 Without patch:
 "(eval):1:in `block in <main>': "
 ""
 ["(eval)", 1]
 ["eval_test.rb", 14]
 
 With patch:
 "(eval):1:in `block in <main>': "
 "(eval):1:in `block in <main>': "
 ["(eval)", 1]
 ["(eval)", 1]
 
 Knowing the line of an error inside eval is useful. Passing a binding
 shouldn't discard that information. Present behavior is even wrong:
 there's no line 10 in this file.
