Almost all cops are starting as disabled until we can fix their
violations.

Changelog: https://github.com/rails/activerecord-session_store/releases/tag/v1.0.0

Includes Rails 5 support.

We don’t use any of the deprecated finders, so it should be safe to
remove.

Resolves #17015.

Instead the script is now included directly from the vendor directory.

Resolves #17166.

In 8278b763 the default behaviour of annotation
has changes, which was causing a lot of noise in diffs. We decided in #17382
that it is better to get rid of the whole annotate gem, and instead let people
look at schema.rb for the columns in a table.

Fixes: #17382

This reverts commit 1cc614f2.

It was causing the ActiveJob integration to fail, so unfortunately we'll have to add the gem again.

This allows the removal of the monkey patch from this commit: 47ff1c56

It'll also make it slightly easier to upgrade to 3.5.0 later.

Changelog: https://github.com/rspec/rspec-rails/blob/master/Changelog.md#340--2015-11-11

Closes #13357

I’d rather upgrade one major version at a time, so Doorkeeper needs to
be upgraded to 3.x before it can be upgraded to 4.x (which includes
Rails 5 support).

Changelog:
https://github.com/doorkeeper-gem/doorkeeper/blob/master/NEWS.md#310

The extra gem isn’t necessary anymore since Rails 4.2 has ActiveJob integration.

Resolves #15575.

Sent emails in the development environment will no longer automatically
be opened in the browser. If a sent email needs to be viewed, it can be
found at the `/rails/letter_opener` route.

Spring changelog: https://git.io/vVAUY

Changelogs:
https://github.com/rails/jquery-rails/blob/master/CHANGELOG.md
https://blog.jquery.com/2016/01/08/jquery-2-2-and-1-12-released/
https://github.com/rails/jquery-ujs/releases

Includes compatibility with Rails 5. We don’t have any tests for this,
so no need to run them. [ci skip]

Changelog: https://github.com/ctran/annotate_models/releases/tag/v2.7.0

Working towards #14286.

Sprockets 3.5.0 reintroduces GZIP-ing and 3.6.0 includes performance improvements. Changelog: https://github.com/rails/sprockets/blob/3.x/CHANGELOG.md

Resolves #14344.

This removes a few dependencies! It was also rude to be using coveralls
0.8.9, considering 0.8.12 introduced support for GitLab CI :) Also
paves the way for updating mime-types to 3.0.

Coveralls Changelog:

Simplecov Changelog:
https://github.com/colszowka/simplecov/blob/master/CHANGELOG.md

This was originally suggested by @ayufan and modified to be a bit
cleaner and use RequestStore instead of a regular Hash.

By caching the output of the two methods involved the number of queries
is reduced significantly. For example, for an issue with 200 notes (of
which 100 reference a number of merge requests) this cuts down the
amount of queries from around 6300 to around 3300.

Includes compatibility with Rails 5.

See the changelog for more information (https://github.com/modeset/teaspoon/blob/master/CHANGELOG.md).

Includes support for Rails 5, bug fixes, and various additional
vulnerability checks.

Discussed in #14233.

This builds on the changes introduced in
https://gitlab.com/gitlab-org/gitlab_git/merge_requests/72 and results
in merge requests with large diffs (e.g. due to them containing minified
CSS) loading much faster.

This reverts commit 01160fc0, reversing
changes made to 4bff9daf.

Add SCSS Lint, CSSComb config file, run SCSS Lint in GitLab CI, add documentation for SCSS Style Guide.
