We trust staff + tl2 and up to perform edits in grace period.
Allow them significantly more edit room in grace period prior to storing
a revision.
editing_grace_period_max_diff_high_trust applies to users with tl2 and up.
So
tl0 / 1 : we store an extra revision if more than 100 chars change
tl2 and up : we store an extra revision if more than 400 chars change
We may tweak these numbers as we go.
If a user performs a substantive edit of 20 chars or more during grace period
we will store a revision to track the change
This allows for better auditing of changes that happen during the grace period
Since rspec-rails 3, the default installation creates two helper files:
* `spec_helper.rb`
* `rails_helper.rb`
`spec_helper.rb` is intended as a way of running specs that do not
require Rails, whereas `rails_helper.rb` loads Rails (as Discourse's
current `spec_helper.rb` does).
For more information:
https://www.relishapp.com/rspec/rspec-rails/docs/upgrade#default-helper-files
In this commit, I've simply replaced all instances of `spec_helper` with
`rails_helper`, and renamed the original `spec_helper.rb`.
This brings the Discourse project closer to the standard usage of RSpec
in a Rails app.
At present, every spec relies on loading Rails, but there are likely
many that don't need to. In a future pull request, I hope to introduce a
separate, minimal `spec_helper.rb` which can be used in tests which
don't rely on Rails.
FIX: history revision can now properly be hidden
FIX: PostRevision serializer is now entirely dynamic to properly handle
hidden revisions

them)
UX: remove CSS transitions on the buttons in the history modal
FIX: PostRevisor now handles all the changes that might create new
revisions
FIX: PostRevision.ensure_consistency! was wrong due to off by 1
