2

I'm looking into updating this enormous web site. Its huge. It uses Ruby 1.9.3-p448, Rails 3.2.17, and Spree 2.0.0. I'd love to push it to Ruby 2.1.1, Rails 4.1-stable, and Spree 2.1.0.

First things first:

I went to the gemfile and on line 2 wrote ruby '2.1.1'. This is to do number 1: upgrade the language itself. In the terminal I did the usual bundle and got an error. Discovered the debugger gem doesn't work in 2.x territory. Highlighted it. Pushed delete. Chuckled. Ran bundle. Smiled of delight as it was so nice to see everything work with such a complex system.

Then I ran bundle exec rake db:test:prepare...

First error:

rake aborted!

My question here really isn't how do I fix this or why is it all breaking, but do you have any pointers? How do I find out where Digest::Digest is coming from? We aren't using it in the site, therefore its a gem problem. I'm probably going to have to deal with more of those "deprecation" warnings, so before I blow hours and hours on it, I just need to know if anyone else has had to go through anything of what I'm attempting right now.

Horror stories much appreciated.

I don't think Digest is the cause of your problems. It seems that MySQL can't connect to your database correctly. Are you sure that your config/database.yml settings are correct for your current environment?

I don't know for certain, but if the error is pointing directly at this line then it's my best guess that you've got your database mis-configured within config/database.yml.

  • The site has been running for ages. I don't think its a database problem unless there were changes in the way Rails or Spree interact with the DB from 3.2 -> 4.1 and 2.0 -> 2.1 respectively. I'm really just wondering what all my errors are going to be. I'll be following the Rails and Spree upgrade guides. I'm more concerned about how I can spend two weeks upgrading rather than two months. Will Spree 2.0.x work with Rails 3.2.17? – BenMorganIO Mar 14 '14 at 16:31
  • If the error is coming from within MySQL's library then it would indicate to me a database problem. Spree does nothing about your database, so it's not a Spree problem. Please check your database settings. Yes Spree 2.0.x will work with the latest version of Rails. – Ryan Bigg Mar 15 '14 at 22:40
  • Thanks, this helps cut up the process of upgrading the site. The digest problem is probably associated to errors such as these http://stackoverflow.com/questions/21184960/ruby-digestdigest-is-deprecated-use-digest. Glad I don't have to upgrade Spree and Rails at the same time (pheew...). – BenMorganIO Mar 16 '14 at 03:14

I've found that I get the same error message whenever my installed version of csv_builder is out of sync with my installed version of MRI.

I see you're using MRI 2.1.1 and csv_builder 2.1.0. You can possibly fix this issue by removing the iconv gem, and bumping your version of csv_builder so that it matches the version of MRI:

# Gemfile
gem 'csv_builder', '2.1.1'

> bundle update csv_builder
> bundle exec rake tes

Worked for me... YMMV etc
