- CR feedback from @egilburg
Additionally
- Move logic for colorizing the payload name into a separate method
- Make some `ActiveRecord::LogSubscriber` instance methods private for clarity:
- `colorize_payload_name`
- `sql_color`
- `logger`
- Improve Changelog Documentation

- Improves coloring for statements like:
# Become WHITE
SELECT * FROM (
SELECT * FROM mytable FOR UPDATE
) ss WHERE col1 = 5;
LOCK TABLE table_name IN ACCESS EXCLUSIVE MODE;
# Becomes RED
ROLLBACK
- Reinstates the coloration of the `payload[:name]`.
Instead of simple alternating colors, adds meaning:
- `MAGENTA` for `"SQL"` or `blank?` payload names
- `CYAN` for Model Load/Exists
- Introduces specs for sql coloration.
- Introduces specs for payload name coloration.

Validate multiple contexts on `valid?` and `invalid?` at once

validates_presence_of :title, on: :update

person = Person.new

Removes mandatory arguments from AR exceptions
|
| | | | | | | | | | | | | |
| | | | | | | | | | | | |
| | | | | | | | | | | | |
| | | | | | | | | | | | |
| | | | | | | | | | | | |
| | | | | | | | | | | | | |
This change allows to instantiate all ActiveRecordError descendant
execption classes without arguments, which might be useful in testing
and is far less surprising than mandatory arguments.

Define `SchemaStatements#tables` as interface

| | | | | | | | | | | | | | |
These 3 methods expect `ConnectionAdapters` to have `tables` method,
so make it clear that `tables` method is interface.
* `ConnectionAdapters::SchemaCache#prepare_tables`
* `db:schema:cache:dump` task
* `SchemaDumper#tables`

Add tests for test/cases/adapters/mysql2/view_test.rb

Basically view tests for MySQL are same with
`test/cases/adapters/postgresql/view_test.rb`.
So move `test/cases/adapters/postgresql/view_test.rb` to
`test/cases/view_test.rb` and make them only run if
`current_adapter` supports writable view.

Its value never change since associations are defined at class load time
so there is no need to build the hash everytime the method is called.

Many user look `desc` of rake task and they are not familiar with `AR`.
`Active Record` is more familiar word.

Apparently I managed to forget how similar the "tests passing" and
"no status reported" merge indicators look.
Note that the previous `stubs` in test_add_index wasn't working:
the method was still called, and just happened to return false.

Sometimes opts passed in might respond to ==, e.g. `Arel::Nodes::Grouping`. In this case, `opts == :chain` returns `Arel::Nodes::Equality` which causes odd behaviour. Prefer `if :chain == opts` which guarantees that `Symbol#==` would be invoked. Alternatively consider `eql?`.
