This is the behavior I naively expect for the operator when used with a
single digit, but it's definitely an edge case for it, and it doesn't
seem to work as expected for including prereleases.

Using >= works fine and make the intention more clear anyways.

bundle update resque-scheduler to latest version

Only build middleware proxy when instrumentating

The instrumentation proxy adds three stack frames per-middleware, even
when nothing is listening.

This commit, when the middleware stack is built, only adds
instrumentation when the `process_middleware.action_dispatch` event has
already been subscribed to.

The advantage to this is that we don't have any extra stack frames in
apps which don't need middleware instrumentation.

The disadvantage is that the subscriptions need to be in place when the
middleware stack is built (during app boot). I think this is likely okay
because temporary AS::Notifications subscriptions are strongly
discouraged.

Fix indentation for config.eager_load nil warning message

Update testing guide to reflect changes from #36047 [ci skip]

Resque 2.0 includes grammar fixes for warnings tickled by our tests. Updating resque-scheduler also requires and updates resque to version 2.0.

```
$ ruby -v
ruby 2.6.2p47 (2019-03-13 revision 67232) [x86_64-linux]
```

In #36047 we moved `take_failed_screenshot` from an `after_teardown`
hook to a `before_teardown` hook. However, I didn't realize the Testing
rails guide was explicitly mentioning that it happened inside
`after_teardown`. So this updates the docs to be consistent with that
change.

[ci skip]

This offenced code is introduced from forward ported #36196, since looks
like 6-0-stable branch isn't checked by CodeClimate.

Hide malformed parameters from error page

Accidentally merged this to 6-0-stable so forward porting it to master
here instead.

Remove ignored_sql from SQLCounter by adding "TRANSACTION" to log name

This commit adds "TRANSACTION" to savepoint and commit, rollback statements
because none of savepoint statements were removed by #36153 since they are not "SCHEMA" statements.

Although, only savepoint statements can be labeled as "TRANSACTION"
I think all of transaction related method should add this label.

Follow up #36153

Fixed typo of dot position [skip ci]

The initializer receives `nil` for these options when no cofigurations were given:

Should attempt `committed!`/`rolledback!` to all enrolled records in the transaction

Remove unnecessary find_partial method

Currently, `committed!`/`rolledback!` will only be attempted for the
first enrolled record in the transaction, that will cause some
problematic behaviors.

The first one problem, `clear_transaction_record_state` won't be called
even if the transaction is finalized except the first enrolled record.
This means that de-duplicated records in the transaction won't refer
latest state (e.g. won't happen rolling back record state).

The second one problem, the enrolled order is not always the same as the
order in which the actions actually happened, the first enrolled record
may succeed no actions (e.g. `destroy` has already succeeded on another
record during `before_destroy`), it will lose to fire any transactional
callbacks.

To avoid both problems, we should attempt `committed!`/`rolledback!` to
all enrolled records in the transaction.

The `GC.start` was added at b29e8936, but the finalizer has been removed
at 7d0ce785 in #35036.

Clear Resolvers' cache after RenderTestCases tests

The templates rendered in RenderTestCases tests will be cached by the
resolvers unexpectedly. And this will break other tests when executed in
certain order. (See https://github.com/rails/rails/issues/36154 for more
detail)

So to fix this issue, we just need to clear the caches on all resolvers.

The virtual attributes(`attachment` and `rich_text`) can't set value
with `fill_in`. So avoid using it. Once #35885 is merged, will be
modified to use it.

Also, add checking attachment attached or not for avoiding
`DelegationError` when attachment didn't attach.

This fixes the following warnings.

```
/rails/activemodel/test/cases/nested_error_test.rb:9: warning: method redefined; discarding old test_initialize
/rails/activemodel/test/cases/error_test.rb:29: warning: previous definition of test_initialize was here
```

[ci skip] Correct the stylesheet name used in the guide.

In the Action Text guides, `app/assets/stylesheets/actiontext.css`
is specified as the file used to style the Action Text editor and
content but the actual file generated from `rails action_text:install`
is `app/assets/stylesheets/actiontext.scss`.

This change simply corrects the file extension shown in the guide.
