* Bump rubocop to 0.82
The `Layout/Tab` cop has been renamed to `Layout/IndentationStyle`
ref: https://github.com/rubocop-hq/rubocop/releases/tag/v0.82.0
No other code changes required.
* Bump rubocop-rails to 2.5.2
No code-changes required.
[Tejas Bubane + Rafael Mendonça França]
Updated the default Ruby workflow:
* Trigger this action for pull request and push
* Install requried OS packages for Active Record connection adapters
* Removing `gem install bundler` because Ruby 2.6 already installs it
* Run RuboCop in parallel by `bundle exec rubocop --parallel`
* Rename `ruby.yml` to `rubocop.yml` to represent the workflow
Bump RuboCop to 0.76.0 and rename `Style/UnneededPercentQ` to `Style/RedundantPercentQ`
```ruby
$ bundle exec rubocop
Error: The `Style/UnneededPercentQ` cop has been renamed to `Style/RedundantPercentQ`.
(obsolete configuration found in .rubocop.yml
```
Removed `.codeclimate.yml`
After having run the railties tests locally and running Rubocop, you'd
see lots of violations for the Rails apps generated in tmp folders.
Don't consider those violations as violating.
Performance cops will be extracted from RuboCop to RuboCop Performance
when next RuboCop 0.68 will be released.
https://github.com/rubocop-hq/rubocop/issues/5977
RuboCop 0.67 is its transition period.
Since rails/rails repository uses Performance cops, This PR added
rubocop-performance gem to Gemfile.
And this PR fixes some offenses using the following auto-correct.
```console
% bundle exec rubocop -a

We need this in order to be able to add this migration for users that
use ActiveStorage during update their apps from Rails 5.2 to Rails 6.0.
Related to #33405
`rake app:update` should update active_storage
`rake app:update` should execute `rake active_storage:update`
if it is used in the app that is being updated.
It will add new active_storage's migrations to users' apps during update Rails.

* Enable `Lint/UselessAssignment` cop to avoid unused variable warnings
Since we've addressed the warning "assigned but unused variable"
frequently.
370537de053040446cec5ed618e19276ebafe594
And also, I've found the unused args in c1b14ad which raises no warnings
by the cop, it shows the value of the cop.
Generally followed the pattern for https://github.com/rails/rails/pull/32034
* Removes needless CI configs for 2.4
* Targets 2.5 in rubocop
* Updates existing CHANGELOG entries for fewer merge conflicts
* Removes Hash#slice extension as that's inlined on Ruby 2.5.
* Removes the need for send on define_method in MethodCallAssertions.
Since Rails 6.0 will support Ruby 2.4.1 or higher
`# frozen_string_literal: true` magic comment is enough to make string object frozen.
This magic comment is enabled by `Style/FrozenStringLiteralComment` cop.
* Exclude these files not to auto correct false positive `Regexp#freeze`
- 'actionpack/lib/action_dispatch/journey/router/utils.rb'
- 'activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb'
It has been fixed by https://github.com/rubocop-hq/rubocop/pull/6333
Once the newer version of RuboCop released and available at Code Climate these exclude entries should be removed.
* Replace `String#freeze` with `String#-@` manually if explicit frozen string objects are required

PR#32381 added Rubocop's comments to some tests files in order to
exclude `Performance/RedundantMerge`.
Turn off `Performance` cops for tests files via `Exclude`
in `.rubocop.yml`.

## Summary
RuboCop 0.58.2 was released.
https://github.com/rubocop-hq/rubocop/releases/tag/v0.58.2
And rubocop-0-58 channel is available in Code Climate.
https://github.com/codeclimate/codeclimate/releases/tag/v0.76.0https://github.com/codeclimate/codeclimate/commit/38f21f0
In addition, the following changes are made in this PR.
- Replace Custom cops with Rails cops
- Add jaro_winkler gem to Gemfile.lock
### Replace Custom cops with Rails cops
These are compatible replacements.
- Replace `CustomCops/AssertNot` cop with `Rails/AssertNot` cop.
- Replace `CustomCops/RefuteNot` cop with `Rails/RefuteMethods` cop.
With this replacement, it was decided to use cop of RuboCop itself.
It removes the code related to CustomCops accordingly.
### Add jaro_winkler gem to Gemfile.lock
Since RuboCop 0.57.0 depends on jaro_winkler gem,
it has been added to Gemfile.lock.
Use attr_reader/attr_writer instead of methods
method is 12% slower
Use flat_map over map.flatten(1)
flatten is 66% slower
Use hash[]= instead of hash.merge! with single arguments
merge! is 166% slower
See https://github.com/rails/rails/pull/32337 for more conversation
This commit fix pattern of filenames for `CustomCops/AssertNot` and
`CustomCops/RefuteNot`.
rubocop should check every file under `test/`.
Related to #32441, #32605
We added `assert_not` in f75addd "to replace warty 'assert !foo'".
fa8d35b agrees that it is warty, and so do I. This custom Rubocop rule
turns the wart into a violation.
As with my last custom cop, https://github.com/rails/rails/pull/32441,
I want to make sure this looks right on code climate before pushing
another commit to autocorrect everything.
@toshimaru I just noticed
https://github.com/toshimaru/rubocop-rails/pull/26
Is there a better way to add these custom cops, or were you saying we
shouldn't have custom cops at all?
Since at least cf4afc4 we have preferred `assert_not` methods over
`refute` methods. I have seen plenty of comments in PRs about this,
and we have tried to fix it a few times (5294ad8, e45f176, 8910f12,
41f50be, d4cfd54, 48a183e, and 211adb4), but the `refute` methods
keep sneaking back in.
This custom RuboCop will take care of enforcing this preference, so we
don't have to think about it again. I suspect there are other similar
stylistic preferences that could be solved with some custom RuboCops, so
I will definitely keep my eyes open. `assert_not` over `assert !` might
be a good candidate, for example.
I wasn't totally sure if `ci/custom_cops` was the best place to put
this, but nothing else seemed quite right. At one point I had it set up
as a gem, but I think custom cops like this would have limited value
in another context.
I want to see how code climate handles the new cops before
autocorrecting the existing violations. If things go as expected, I will
push another commit with those corrections.
