FileUtils.cp in 1.9 doesn't preserve permissions unless :preserve is set
|ruby -v:||ruby 1.9.3dev (2011-03-18 trunk 31122) [x86_64-darwin10.6.0]||Backport:|
By default /bin/cp preserves file permissions when copying a file, -p flag is meant for preserving uid, gid, mtime etc. However with FileUtils.cp in 1.9 permissions are only copied when :preserve => true option is given. I think the least surprise behavior would be to mimic cp behavior.
Patch is attached.
