Subject: [ruby-core:38822] Line endings, bug/regression or feature of 1.9.3?

Hello,

Seems Redmine is down, so emailing the list.

One user detected that Ruby 1.9.3-preview1 and latest changes in
ruby_1_9_3 branch generates incorrectly line endings on Windows.

It seems that now, by default, it uses LF instead of CRLF for writing,
unless you explicitly indicate text-mode ('t')

Full investigation of the user is found here:

http://groups.google.com/group/rubyinstaller/msg/65cd1284e10ffe71

And simple test:

V:\>ruby -ve "n = 'foo.txt'; File.open(n, 'w') { |f| f.puts 'Hello' };
puts File.size(n)"
ruby 1.9.3dev (2011-08-06 revision 32868) [i386-mingw32]
6

Hello + CRLF should have been 7 bytes

V:\>ruby -ve "n = 'foo.txt'; File.open(n, 'wt') { |f| f.puts 'Hello'
}; puts File.size(n)"
ruby 1.9.3dev (2011-08-06 revision 32868) [i386-mingw32]
7

V:\>ruby -ve "n = 'foo.txt'; File.open(n, 'wb') { |f| f.puts 'Hello'
}; puts File.size(n)"
ruby 1.9.3dev (2011-08-06 revision 32868) [i386-mingw32]
6

Is this an intended change? is not mentioned on NEWS.

I personally don't complain (we all know the pain of binary versus
text-mode for opening files) but seems to be a huge difference between
1.9.2 and 1.9.3

Please comment.

Thank you.
