Alex Khesin created JRUBY-6318:
----------------------------------
Summary: Tempfile#open does not return the value of the block
given to it
Key: JRUBY-6318
URL: https://jira.codehaus.org/browse/JRUBY-6318
Project: JRuby
Issue Type: Bug
Components: Standard Library
Affects Versions: JRuby 1.6.5, JRuby 1.7
Reporter: Alex Khesin
Assignee: Thomas E Enebo
Tempfile#open's behavior has changed from 1.8 to 1.9, but that change has not
been reflected in JRuby 1.9 mode. When given a block, it used to return nil in
1.8, but in 1.9 it is supposed to return the value of the block. JRuby in 1.9
mode continues to return nil.
in MRI ruby I get:
$ irb
1.9.3p0 :001 > require 'tempfile'
1.9.3p0 :006 > Tempfile.open('foo') { |tmp| tmp.path }
=> "/tmp/foo20120105-20998-z3gawt"
In JRuby, however:
$ JRUBY_OPTS=--1.9 irb
jruby-1.7.0.dev :001 > require 'tempfile'
jruby-1.7.0.dev :002 > Tempfile.open('foo') { |tmp| tmp.path }
=> nil
