* The database version will get cached in the schema cache file during the
schema cache dump. When the database version check happens, the version will
be pulled from the schema cache and thus avoid querying the database for
the version.
* If the schema cache file doesn't exist, we'll query the database for the
version and cache it on the schema cache object.
* To facilitate this change, all connection adapters now implement
#get_database_version and #database_version. #database_version returns the
value from the schema cache.
* To take advantage of the cached database version, the database version check
will now happen after the schema cache is set on the connection in the
connection pool.

We as Arm Treasure Data are using Optimizer Hints with a monkey patch
(https://gist.github.com/kamipo/4c8539f0ce4acf85075cf5a6b0d9712e),
especially in order to use `MAX_EXECUTION_TIME` (refer #31129).
Example:
```ruby
class Job < ApplicationRecord
default_scope { optimizer_hints("MAX_EXECUTION_TIME(50000) NO_INDEX_MERGE(jobs)") }
end
```
Optimizer Hints is supported not only for MySQL but also for most
databases (PostgreSQL on RDS, Oracle, SQL Server, etc), it is really
helpful to turn heavy queries for large scale applications.

Adds a method to ActiveRecord allowing records to be inserted in bulk without instantiating ActiveRecord models. This method supports options for handling uniqueness violations by skipping duplicate records or overwriting them in an UPSERT operation.
ActiveRecord already supports bulk-update and bulk-destroy actions that execute SQL UPDATE and DELETE commands directly. It also supports bulk-read actions through `pluck`. It makes sense for it also to support bulk-creation.

MySQL 8.0.13 and higher supports default value to be a function or
expression.

Six Mocha calls prove quite resistant to Minitestification. For example,
if we replace
```
ActiveRecord::Associations::HasManyAssociation
.any_instance
.expects(:reader)
.never
```
with `assert_not_called`, Minitest wisely raises
```
NameError: undefined method `reader' for class `ActiveRecord::Associations::HasManyAssociation'
```
as `:reader` comes from a deeply embedded abstract class,
`ActiveRecord::Associations::CollectionAssociation`.
This patch tackles this difficulty by adding
`ActiveSupport::Testing::MethodCallAsserts#assert_called_on_instance_of`
which injects a stubbed method into `klass`, and verifies the number of
times it is called, similar to `assert_called`. It also adds a convenience
method, `assert_not_called_on_instance_of`, mirroring
`assert_not_called`.
It uses the new method_call_assertions to replace the remaining Mocha
calls in `ActiveRecord` tests.

This has been possible since Mocha v1.0 and makes it clear that we want
Mocha to integrate with Minitest, not Test::Unit.

we have chosen to go with double quotes by default.

Fractional Seconds supported version is 5.6.4 or higher.

Specifically, versions of MySQL prior to 5.6 do not support this, which
is what's used on Travis by default. The method `mysql_56?` appeared to
only ever be used to conditionally apply subsecond precision, so I've
generalized it and used it more liberally.
This should fix the test failures caused by #20317

I’m renaming all instances of `use_transcational_fixtures` to
`use_transactional_tests` and “transactional fixtures” to
“transactional tests”.
I’m deprecating `use_transactional_fixtures=`. So anyone who is
explicitly setting this will get a warning telling them to use
`use_transactional_tests=` instead.
I’m maintaining backwards compatibility—both forms will work.
`use_transactional_tests` will check to see if
`use_transactional_fixtures` is set and use that, otherwise it will use
itself. But because `use_transactional_tests` is a class attribute
(created with `class_attribute`) this requires a little bit of hoop
jumping. The writer method that `class_attribute` generates defines a
new reader method that return the value being set. Which means we can’t
set the default of `true` using `use_transactional_tests=` as was done
previously because that won’t take into account anyone using
`use_transactional_fixtures`. Instead I defined the reader method
manually and it checks `use_transactional_fixtures`. If it was set then
it should be used, otherwise it should return the default, which is
`true`. If someone uses `use_transactional_tests=` then it will
overwrite the backwards-compatible method with whatever they set.

The cause by which the test suite for the mysql adapter broke in 1502cae
(reverted 89ba5bb) is because the precision was not extracted.
The rounding problem in mysql adapter has not been fixed, but `mysql_56`
helper tested only mysql2 adapter, its behavior was not apparent.

This finally removes the warning "WARNING: there is no transaction in progress"
when running Active Record tests using PostgreSQL.
|
|
|
|
|
|
| |
The types that are affected by `time_zone_aware_attributes` (which is on
by default) have been made configurable, in case this is a breaking
change for existing applications.
|
|
|
|
|
|
|
|
| |
Before this change any error raised inside a transaction callback
are rescued and printed in the logs.
Now these errors are not rescue anymore and just bubble up,
as the other callbacks.

Goals:
1. Default to :random for newly generated applications
2. Default to :sorted for existing applications with a warning
3. Only show the warning once
4. Only show the warning if the app actually uses AS::TestCase

Currently, Active Record will rescue any errors raised within
after_rollback/after_create callbacks and print them to the
logs. Next versions of rails will not rescue those errors anymore,
and just bubble them up, as the other callbacks.
This adds a opt-in flag to enable that behaviour, of not rescuing
the errors.
Example:
# For not swallow errors in after_commit/after_rollback
config.active_record.errors_in_transactional_callbacks = true
[fixes #13460]

Calling ActiveSupport::TestCase.i_suck_and_my_tests_are_order_dependent! in AS::TestCase makes
everyone's tests order dependent, which should never be done by the framework.

We are planning to remove mocha from our test suite because of
performance problems. To make this possible we should stop require mocha
on ActionSupport::TestCase.
This should not affect applications since users still need to add mocha
to Gemfile and this already load mocha.
Added FIXME notes to place that still need mocha removal
|
|
|
|
|
|
| |
With ActiveRecord::Properties, we now have a reasonable path for users
to continue to keep this behavior if they want it. This is an edge case
that has added a lot of complexity to the code base.

Follow-Up to https://github.com/rails/rails/pull/14400
This ensures that all tables are removed after each test and thereby
allowing us to run the tests in a random order.
