Issue #11199 has been updated by David Rodrguez.


Hi!

We run into this here: https://github.com/janko-m/shrine/commit/399adcecad64c66ca4ffb1b1619777ff8551e761. That test passes in 2.2.3 but fails in 2.3.0.preview1, apparently due to this issue. Is fixing this planned for 2.3.0?

Thanks a lot.

Bug #11199: IO.copy_stream degrade that can't call pathname to pathname
https://bugs.ruby-lang.org/issues/11199#change-55069

* Author: Yuki Kurihara

----------------------------------------
IO.copy_stream について、2.2.2〜2.3.0dev間で動作に差異がありました。

再現スクリプトを添付します。

~~~ruby
#! /usr/bin/env ruby

require 'pathname'

IO.write "src", "ok"
src = Pathname.new("src")
dst = Pathname.new("dst")
IO.copy_stream src, dst
puts IO.read("dst")
~~~

~~~
$ ruby --version
ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin14]
$ ruby copy_stream.rb
ok
~~~

~~~
$ ruby --version
ruby 2.3.0dev (2015-05-30 trunk 50686) [x86_64-darwin14]
$ ruby copy_stream.rb
copy_stream.rb:8:in `read': no implicit conversion from string (TypeError)
	from copy_stream.rb:8:in `read'
	from copy_stream.rb:8:in `copy_stream'
	from copy_stream.rb:8:in `<main>'
~~~

仕様変更でなければ、互換性を壊さないために2.2.2の動作を期待します。
