Daniel Berger created JRUBY-6444:
------------------------------------
Summary: RangeError vs TypeError with FFI
Key: JRUBY-6444
URL: https://jira.codehaus.org/browse/JRUBY-6444
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.6.6
Environment: jruby 1.6.6 (ruby-1.8.7-p357) (2012-01-30 5673572) (Java
HotSpot(TM) 64-Bit Server VM 1.6.0_29) [darwin-x86_64-java]
Reporter: Daniel Berger
Assignee: Thomas E Enebo
Priority: Minor
When passing an invalid type to an FFI function that requires an integer, JRuby
raises a RangeError, whereas the C version raises a TypeError. I would expect a
TypeError.
{noformat}
require 'ffi'
class Admin
extend FFI::Library
ffi_lib FFI::Library::LIBC
attach_function :getpwuid, [:int], :pointer
def self.get_user(uid)
ptr = getpwuid(uid)
end
end
Admin.get_user('foo') # TypeError using MRI, RangeError using JRuby
{noformat}
