Struct#new behavior differs from MRI
------------------------------------
Key: JRUBY-1597
URL: http://jira.codehaus.org/browse/JRUBY-1597
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.x
Environment: Ubuntu Linux 7.10,
ruby 1.8.5 (2007-11-21 rev 4842) [i386-jruby1.1b1]
Reporter: Vladimir Sizikov
Priority: Minor
Rubinius spec tests have one particular test case that verifies that
Struct.new(), invoked with Object as a first parameter, uses Object.to_str to
convert the object to the name. That's how MRI (and Rubinius) operate, but I
wasn't able to find any supporting wording in the official docs.
Code:
obj = Object.new
def obj.to_str() "Foo" end
struct = Struct.new(obj)
MRI: ===> Struct::Foo
JRuby: ===> #<Class:01x12943ac> (anonymous struct with no name)
This leads to Rubinius spec test failure:
#> bin/mspec -t jruby spec/core/struct
Struct.new calls to_str on its first argument (constant name) FAILED
uninitialized constant Struct::Foo:
