- MariaDB 10.3.7 is the first GA release
https://mariadb.com/kb/en/library/mariadb-1037-release-notes/
- MariaDB 10.3 translates `LENGTH()` to `OCTET_LENGTH()` function
https://mariadb.com/kb/en/library/sql_modeoracle-from-mariadb-103/
> MariaDB translates LENGTH() to OCTET_LENGTH()
- MySQL does NOT translate `LENGTH()` to `OCTET_LENGTH()`
However, it translates `OCTET_LENGTH()` to `LENGTH()`
Here are generated schema dumps of this test to show the differences
between MySQL and MariaDB:
* MySQL 8.0 (Server version: 8.0.11 MySQL Community Server - GPL)
```ruby
create_table \"virtual_columns\", options: \"ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci\", force: :cascade do |t|
t.string \"name\"
t.virtual \"upper_name\", type: :string, as: \"upper(`name`)\"
t.virtual \"name_length\", type: :integer, as: \"length(`name`)\", stored: true
t.virtual \"name_octet_length\", type: :integer, as: \"length(`name`)\", stored: true
end
```
* Maria DB 10.3 (Server version: 10.3.7-MariaDB-1:10.3.7+maria~bionic-log mariadb.org binary distribution)
```ruby
create_table \"virtual_columns\", options: \"ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci\", force: :cascade do |t|
t.string \"name\"
t.virtual \"upper_name\", type: :string, as: \"ucase(`name`)\"
t.virtual \"name_length\", type: :integer, as: \"octet_length(`name`)\", stored: true
t.virtual \"name_octet_length\", type: :integer, as: \"octet_length(`name`)\", stored: true
end

Poppler is licensed under the more liberal GPL, making it a good alternative for those who can't use mutool.
Since #32034 Rails 6 requires Ruby 2.4.1 or higher.
Two CI jobs configured with the latest version of`jruby-9.1.15.0`
compatibile with Ruby 2.3.3 are getting errors:
https://travis-ci.org/rails/rails/jobs/343519339
```
Bundler could not find compatible versions for gem "ruby":
In Gemfile:
ruby java
rails java was resolved to 6.0.0.alpha, which depends on
ruby (>= 2.4.1) java
Could not find gem 'ruby (>= 2.4.1)', which is required by gem 'rails', in any
of the relevant sources:
```
I'm not sure cause, but due to the influence of `gem clean`, the expected
gem seems not to be installed correctly.
In order to avoid a test failure due to this, I fixed that `gem clean` not be executed.

This is a workaround. If Travis fixes something, please revert this.
Simplify our dev testing and CI story since we're also testing against
Redis for the Active Support cache store.
Directly test whether db, host, password, etc are passed through as
config instead of spinning up a Redis server with a password set on it.
when tested with ruby-head
This pull request attempts to ignore the following error
when tested with ruby-head which has bundler as a default gem.
```ruby
$ rvm @global do gem uninstall bundler --all --ignore-dependencies --executables
ERROR: While executing gem ... (Gem::InstallError)
gem "bundler" cannot be uninstalled because it is a default gem
The command "rvm @global do gem uninstall bundler --all --ignore-dependencies --executables" failed and exited with 1 during .
```
Refer https://travis-ci.org/rails/rails/jobs/295600391
This workaround should be removed once https://github.com/bundler/bundler/issues/6072 is addressed.
- Adds RedisAdapterTest::AlternateConfiguration to account
for a relatively common alternative setup, as it’s used
as the first example in the
[Redis rubygem](https://github.com/redis/redis-rb#getting-started)
- Supplies original RedisAdapterTest with more complete
redis:// url format by adding a ‘userinfo’ (blank user),
so that it resembles the alternate configuration
- Supplies original EventedRedisAdapterTest with more complete
redis:// url as well
- Adds before_script to start redis-server with password as a daemon
and with explicit defaults copied from the default redis.conf
(Instead of using Travis' default init/upstart scripts for `redis` service)
Also, explicitly apply the order: generate_subscripts is unlikely to
start returning values out of order, but we should still be clear about
what we want.
