A plugin for upgrading to newer versions of Workarea and its plugins.

• Used for upgrading to new patches, minors, or majors
• View a report of the complexity of the upgrade
• Diff code change between any two version of Workarea in the v3 series
• See results relevant to the overridden or decorated files in your application

• Command Line Interface

  The features of this plugin are accessibile by invoking the workarea_upgrade command. After installing this plugin run bundle exec workarea_upgrade help for an overview of which commands are available to you.

• Upgrade Preparation

  The Upgrade plugin uses the differences found between your Gemfile and a Gemfile.next file present in your application's root directory to generate its reporting and diffing functionality. You can create and manage this Gemfile.next yourself or use the prepare task to automate its creation.

• Reporting

  To get an idea of how complex your upgrade will be the Upgrade gem provides a report task which shows basic statistics about the amount of change the Workarea platform has undergone between versions listed in your Gemfile and Gemfile.next. These statistics should give you a general idea of how much work may be required to perform the upgrade.

• Diffing

The Upgrade plugin will display a full diff of changes made to Workarea as they pertain to your application. If you've overridden or decorated any core Workarea file or a file from a Workarea plugin the Upgrade gem will show you the change to that file between the versions specified in your Gemfile and Gemfile.next. Use this information to upgrade your application accordingly.

Add the plugin to your application's Gemfile:

group :development do
  gem 'workarea-upgrade', '>= 3.0.0', source: 'https://gems.workarea.com'
end

Update your bundle. Use bundle update to get the latest version:

cd path/to/your_app
bundle update workarea-upgrade

Run workarea_upgrade help for an overview of the commands and what they do:

bundle exec workarea_upgrade help

Run workarea_upgrade help TASK to get more information about a given task:

bundle exec workarea_upgrade help report

The Upgrade plugin uses a Gemfile.next file in your application's root directory to determine the versions you wish to upgrade to.

This file may be created manually, by copying and modifying your Gemfile as a Gemfile.next file, or automatically, by running:

bundle exec workarea_upgrade

This will drop you into a wizard that will determine the newest versions of each of your Workarea gems and iterate over them, allowing you to add, remove, or modify the version of each gem found. These choices are used to generate the Gemfile.next file for you automatically.

Once the process is complete the Gemfile.next will be tested for installation. If it fails installation you will be given instructions on how to fix it manually until it is in an installable state.

Once the Gemfile.next file is installable, you may get an idea of the complexity of your upgrade by viewing the report:

bundle exec workarea_upgrade report

Finally, view the actual changes that have occurred to any Workarea gems you have installed with:

bundle exec workarea_upgrade diff

The output of this command will be limited to the files that have been overridden or decorated in your application only, as its these files that will not automatically receive the updates from the core platform. Use this output to make informed decisions about how your application will need to change to stay up to date.

You may also view a list of all files added or removed between each version by running either:

bundle exec workarea_upgrade diff --added # or
bundle exec workarea_upgrade diff --removed

View bundle exec workarea_upgrade help diff for more ways you can format these results.

Once all of the updates have been applied to your application, move the Gemfile.next files over to replace your Gemfile files:

mv Gemfile.next Gemfile
mv Gemfile.next.lock Gemfile.lock

Lastly you should run your test suite to ensure all of the tests pass:

bin/rails workarea:test

Once the tests pass, deploy your upgrade to your QA environment for real user testing.

Themes, by nature, are structured differently than host applications. The main difference is that themes list their dependencies in a gemspec instead of a Gemfile. Secondly, they are more permissive in their dependencies, since they are intended to "just work" for all patches within a dependency's minor version or, in some cases, all minors and patches within a dependency's major version.

# snipped from the NVY Theme's gemspec

s.add_dependency 'workarea', '~> 3.4.x'                                       
s.add_dependency 'workarea-theme', '~> 1.1.1'

s.add_dependency 'workarea-slick_slider', '~> 1.x'

# snipped from the NVY theme's Gemfile

gem 'workarea', github: 'workarea-commerce/workarea'

In order to use the workarea_upgrade command effectively within the context of a theme you will need to temporarily create entries in the theme's Gemfile effectively fixing the theme's dependencies to a known version before proceeding with the upgrade.

Doing this is fairly straightforward. It's best to glean the fixed dependency versions from the gemspec directly. Using the example above we can safely assume the adjusted Gemfile should look something like this:

gem 'workarea', '3.4.0'
gem 'workarea-blog', '3.3.0'
gem 'workarea-gift_cards', '3.4.0'
gem 'workarea-product_quickview', '2.0.2'
gem 'workarea-reviews', '3.0.0'
gem 'workarea-share', '1.2.0'
gem 'workarea-swatches', '1.0.0'
gem 'workarea-styled_selects', '1.0.0'
gem 'workarea-slick_slider', '1.0.0'
gem 'workarea-wish_lists', '2.1.0'

# Don't forget to include workarea-upgrade either
gem 'workarea-upgrade', source: 'https://gems.workarea.com'

Running bundle exec workarea_upgrade at this point should work as expected.

Once you've finished going through the generated diff and applying all of the changes, don't forget to

1. revert the changes you made to your Gemfile
2. update your gemspec to point to the new versions you've upgraded to
3. delete your Gemfile.next and Gemfile.next.lock files
4. run a bundle install to check that the dependencies are correct
5. run your tests
