mysql.rb errors after upgrading ruby 7

Posted by Darshan Patil Thu, 09 Aug 2007 05:34:00 GMT

I just noticed that my rails projects broke after I upgraded ruby on my linux box. Projects that had gems and rails frozen break. This is because of code in the SHA1 class not being backward compatible.

To quickly fix a broken rails app that shows the following error: 
vendor/rails/activerecord/lib/active_record/vendor/mysql.rb:551:in `initialize'

edit the mysql.rb file so that the scramble41 routine looks like:

  def scramble41(password, message)
    return 0x00.chr if password.nil? or password.empty?
    buf = [0x14]
    s1 = Digest::SHA1.digest(password)
    s2 = Digest::SHA1.digest(s1)
    x = Digest::SHA1.digest(message + s2)
    (0..s1.length - 1).each {|i| buf.push(s1[i] ^ x[i])}
    buf.pack("C*")
  end

    Man you don’t even know how long I’ve waited for this since disabling my own Movable Type widget (that doesn’t work since Haloscan bypasses that code).

    THANK YOU!

    I tried this but now I get a different error: MySQL Connection dropped during query….anyone see anything like that? What version of Ruby did you upgrade to that caused this error?

    I was installing Mephisto and hit this – voila!

    Thank you!
