Various String methods handle tainted flag incorrectly
------------------------------------------------------
Key: JRUBY-1746
URL: http://jira.codehaus.org/browse/JRUBY-1746
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.x
Environment: Latest JRuby 1.1b1 from trunk.
Reporter: Vladimir Sizikov
Attachments: string-taint.patch
Consider the following example:
{noformat}
p "hello".taint.crypt("other").tainted?
p "hello".crypt("other".taint).tainted?
p "hello".taint.dump.tainted?
p "hello".taint.inspect.tainted?
p ("%s".taint % "hello").tainted?
p "hello".taint.inspect.tainted?
{noformat}
MRI 1.8.6, 1.9 , Rubinius print:
true
true
true
true
true
true
Jruby prints:
false
false
false
false
false
false
:)
This also leads to 4 or 5 rubinius spec failures.
The proposed patch fixes the problem, and the spec failures. Unit tests are
included too.
