Sync the visibility of `sql_for_insert` to private

fix with_routing test helper to make it work with api-only controllers

[ *Kasper Timm Hansen* & *Kir Shatrov* ]

We try to not try! internally.

Make ActiveRecord structure load/dump configurable

Update list of `duplicable?` objects in AS core_ext guide [ci skip]

use Thor option parser in server commands parse

Use `next` instead of `break`; avoid terminating whole loop

We want to avoid terminating the whole loop here, because it will cause
parameters that should be removed to not be removed, since we are
terminating early. In this specific case, `param2` is processed before
`param1` due to the reversing of `route.parts`, and since `param2` fails
the check on this line, it would previously cause the whole loop to
fail, and `param1` would still be in `parameterized_parts`. Now, we are
simply calling `next`, which is the intended behavior.

Introduced by 8ca8a2d7.

Fixes #27454.

Merge pull request #27490 from kamipo/should_not_update_children_when_parent_creation_with_no_reason

Should not update children when the parent creation with no reason

Remove extracting `polymorphic_base_class` for `Array` in `AssociationQueryValue`

This issue was introduced with d849f42b to solve #19782. However, we can
solve #19782 without causing the issue. It is enough to save only when
necessary.

Fixes #27338.

clear all environments log files by default

This reverts commit 6961afef.

We were not able to keep backward compatibility in this case so it is
better to ask people to upgrade with cold cache.

Upgrade to nio4r 2.0.0

nio4r 2.0.0 primarily includes new features and bugfixes, with few breaking
changes. The primary reason for bumping the major version is dropping support
for all Ruby versions prior to 2.2.2, so as to match Rails 5.

Full release announcement here:

Use `#execute` instead of `@connection.query`

do not mutate `object_name` of class in `fields_for`

Some methods were added to public API in
5b14129d and they should be not part of
the public API.

Optimize Journey::Route#score for url_for

Scoring routes based on constraints repeated many type conversions that
could be performed in the outer loop.  Determinations of score and
fitness also used Array operations that required allocations.  Against
my benchmark with a large routeset, this reduced object allocations by
over 30x and wall time by over 3x.
