mkdtemp 1.2.1 released

Version 1.2.1 of the mkdtemp gem was just released. mkdtemp is a wrapper for the mkdtemp() function in the standard C library, and it provides an easy means of securely creating temporary directories from within Ruby code.

This is a bugfix release which brings full compatibility with Ruby 1.9.2 (the "block" functionality added in mkdtemp 1.2 didn’t not work under Ruby 1.9.2 as the body of the block was never evaluated):

# this:            # is a shorthand for:
Dir.mkdtemp do     #   dir = Dir.mkdtemp
  puts Dir.pwd     #   Dir.chdir dir do
end                #     puts Dir.pwd
                   #   end

Note that Ruby’s standard library now includes (since 1.8.7) very similar functionality in the form of mktmpdir (example below), so this release is really just to ease upgrading to newer versions of Ruby for projects that started using mkdtmp in the past. In general, new projects might want to just use the methods in the standard library (although I confess to not having looked at the standard library implementation, so I can’t vouch for its security and freedom from race conditions):

require 'tmpdir'

Dir.mktmpdir do |dir|
  Dir.chdir dir do
    puts "Here I am in #{dir}"
  end
end
