String#inpect and String#dump behavior is different from Ruby
-------------------------------------------------------------
Key: JRUBY-1726
URL: http://jira.codehaus.org/browse/JRUBY-1726
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Environment: JRuby 1.1b1, latest trunk
Reporter: Vladimir Sizikov
Attachments: string-inspect-dump-behavior.patch
Consider the following:
"\010".inspect
MRI 1.8.6 and 1.9 print:
"\"\\b\""
JRuby prints:
"\"\\010\""
This leads to two rubinius spec failures:
String#inspect produces a version of self with all nonprinting charaters
replaced by \nnn notation FAILED
Expected
"\"\\000\\001\\002\\003\\004\\005\\006\\a\\010\\t\\n\\v\\f\\r\\016\\017\\020\\021\\022\\023\\024\\025\\026\\027\\030\\031\\032\\e\\034\\035\\036\\037
!\\\"\\\#$%&'()*+,-./0123456789\""
to equal
"\"\\000\\001\\002\\003\\004\\005\\006\\a\\b\\t\\n\\v\\f\\r\\016\\017\\020\\021\\022\\023\\024\\025\\026\\027\\030\\031\\032\\e\\034\\035\\036\\037
!\\\"\\\#$%&'()*+,-./0123456789\""
