Broken tracing for Kernel.load
------------------------------
Key: JRUBY-2456
URL: http://jira.codehaus.org/browse/JRUBY-2456
Project: JRuby
Issue Type: Bug
Components: Interpreter
Affects Versions: JRuby 1.1.2
Reporter: Martin Krauskopf
Attachments: ThreadContext.patch
Try the below simple sample.
Firstly, where one should get 'nil' for method name, JRuby is passing name of
loaded file.
The attached fix seems to fix it. I can provide mini-test, but
test/test_trace_func.rb is disabled and moreover seems to be broken completely
even in interpreted mode.
Secondly {{Kernel.load}} calls missing at all.
Thirdly the path is absolute. JRuby seems to prepend
{{System.getProperty("user.dir")}} somehwere.
{{code}}
$ cat tester.rb
lineNum = 0
Kernel.set_trace_func(lambda do |event, file, line, id, binding, clazz|
printf "%4d. | %8s | %#{$0.length}s:%-4d | %12s | %8s\n", lineNum+=1, event,
file, line, (id||'<nil>'), clazz
end)
load 'a.rb'
{{code}}
{{code}}
$ cat a.rb
a=5
{{code}}
{{code}}
$ ruby tester.rb
1. | line | tester.rb:5 | <nil> | false
2. | c-call | tester.rb:5 | load | Kernel
3. | line | ./a.rb:1 | <nil> | false
4. | c-return | tester.rb:5 | load | Kernel
{{code}}
{{code}}
$ jruby -J-Djruby.reflection=true -J-Djruby.compile.mode=OFF tester.rb
1. | line | tester.rb:5 | <nil> | false
2. | line | /home/emdot/ruby/tester/lib/stf/./a.rb:1 |
/home/emdot/ruby/tester/lib/stf/./a.rb | false
{{code}}
