Bug #3843: ruby -r tracer prog.rb no longer tracers prog.rb

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: 1.9.2

=begin
The problem appears to be at the end of tracer.rb:

if $0 == FILE

direct call

$0 = ARGV[0]
ARGV.shift
Tracer.on
require $0
elsif caller.size <= 1
Tracer.on
end

IN 1.9.2, caller() at this point is 2 deep:

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

The following change seems to fix it, but it feels a little hacky..

if $0 == FILE

direct call

$0 = ARGV[0]
ARGV.shift
Tracer.on
require $0
elsif caller.size <= 2 && caller.all? {|place| place =~ /custom_require/}
Tracer.on
end
