Caused by #17920.
Closes#19545.
This patch introduced regressions because initializers were no longer
loaded. Specifically missing inflections result in broken restores of
the database.
Preserving RACK_ENV behavior.

`db:test:prepare` still purges the database to always keep the test
database in a consistent state.
This patch introduces new problems with `db:schema:load`. Prior
to the introduction of foreign-keys, we could run this file against
a non-empty database. Since every `create_table` containted the
`force: true` option, this would recreate tables when loading the schema.
However with foreign-keys in place, `force: true` wont work anymore and
the task will crash.

This reverts deprecations added in #13528.
The task is brought back for two reasons:
1. Give plugins a way to hook into the test database initialization process
2. Give the user a way to force a test database synchronization
While `test:prepare` is still a dependency of every test task, `db:test:prepare`
no longer hooks into it. This means that `test:prepare` runs before the schema
is synchronized. Plugins, which insert data can now hook into `db:test:prepare`.
The automatic schema maintenance can't detect when a migration is rolled-back,
modified and reapplied. In this case the user has to fall back to `db:test:prepare`
to force the synchronization to happen.

Closes#16757.
Prior to this patch schema loading rake tasks had the potential to leak a
connection to a different database. This had side-effects when rake tasks
operating on the current connection (like `db:seed`) were chained.
Restore the 4.0 behaviour for 'sqlite3:///', but deprecate it. We'll
change to the absolute-path interpretation in 4.2.
The current "correct" spellings for in-memory, relative, and absolute
URLs, respectively, are:
sqlite3::memory:
sqlite3:relative/path
sqlite3:/full/path

Uncovered by @guilleiguaran while investigating #14495, though that
sounds like a different issue.
* Move check from generated helper to test_help.rb, so that all
applications can benefit
* Rather than just raising when the test schema has pending migrations,
try to load in the schema and only raise if there are pending
migrations afterwards
* Opt out of the check by setting
config.active_record.maintain_test_schema = false
* Deprecate db:test:* tasks. The test helper is now fully responsible
for maintaining the test schema, so we don't need rake tasks for this.
This is also a speed improvement since we're no longer reloading the
test database on every call to "rake test".
By using the URL sub key in the `database.yml` by default we are exposing the ability to set other attributes such as `pool` or `reap_frequency` without need of modifying the URL to contain non-connection specific information.
Right now `db:drop` depends on `load_config` since so when `db:drop` gets executed `load_config` gets run. `db:structure:load` depends on `[:environment, :load_config]`. So before it runs, it executes `environment` but because `load_config` has already executed it is skipped. Note `db:load_config` is "invoke"-d twice, but only "execute"-d once:
```
** Invoke db:drop (first_time)
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:drop
** Invoke db:structure:load (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config
** Execute db:structure:load
```
The fix for this is making sure that the environment is run before any `load_config`:
```
** Invoke environment (first_time)
** Execute environment
** Invoke db:drop (first_time)
** Invoke db:load_config (first_time)
** Execute db:load_config
** Execute db:drop
** Invoke db:structure:load (first_time)
** Invoke environment
** Invoke db:load_config
** Execute db:structure:load
```
Prior to #13463 when `DATABASE_URL` was set, Rails automagically used that value instead of the database.yml. There are tests in dbs_test that expect this to still be true. After that PR, `RAILS_DATABASE_URL` is expected to be read into the YAML file via ERB, this PR fixes that behavior.
Note: this does not entirely fix the tests. It seems that `ActiveRecord::Tasks::DatabaseTasks.current_config` does not process the url string correctly (convert it into a hash), and ` ActiveRecord::Tasks::DatabaseTasks.structure_load(current_config, filename)` as well as other methods in `DatabaseTasks` expect a hash.
It seems like we should involve the resolver somewhere in this process to correctly convert the database url, I do not know the best place for that /cc @josevalim
- added tests to confirm establish_connection uses DATABASE_URL and
Rails.env correctly even when no arguments are passed in.
- updated rake db tasks to support DATABASE_URL, and added tests to
confirm correct behavior for these rake tasks. (Removed
establish_connection call from some tasks since in those cases
the :environment task already made sure the function would be called)
- updated Resolver so that when it resolves the database url, it
removes hash values with empty strings from the config spec (e.g.
to support connection to postgresql when no username is specified).
