FileUtils.cp_r incorrectly produces "same file" error when files to be copied
already exist in destination directory
---------------------------------------------------------------------------------------------------------------------
Key: JRUBY-1943
URL: http://jira.codehaus.org/browse/JRUBY-1943
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.1RC1
Environment: JRuby 1.1RC1, Rails 2.0.2, Mongrel-1.1.3-java, Win XP
Reporter: Raphael Gillett
Fix For: JRuby 1.1
FileUtils copy routines give "same file" error when files to be copied already
exist in destination directory. Amongst other problems, this error causes the
ActiveScaffold 1.1RC1 plugin to abort when run under JRuby.
Test case:
Place identical files in subdirectories temp1 and temp2
Create "filecopying.rb" =>
require 'fileutils'
include FileUtils
directory = File.dirname(__FILE__)
source_path = "/temp1"
destination_path ="/temp2"
source = File.join(directory, source_path)
destination = File.join(directory, destination_path)
FileUtils.cp_r(Dir.glob(source+'/*.*'), destination, :verbose => true)
Running "jruby filecopying.rb" triggers "same file" error.
Under MRI ("ruby filecopying.rb") the pre-existing files in temp2 are
overwritten and no error message is given.
Patch: fileutils.rb
Replace lines
def fu_windows?
/mswin|mingw|bccwin|wince|emx/ =~ RUBY_PLATFORM
end
with
def fu_windows?
/mswin|mingw|bccwin|wince|emx|java/ =~ RUBY_PLATFORM
end
