Ruby-pg's default way to serialize values for transmission to the database is to
call #to_s . This however creates a temporary String object for each value.
Setting a class based type map avoids the allocation of this additional String.
The performance benefit is measurable in microbenchmarks, but not with
the overhead of activerecord. However it's free to use and has no drawback.

The type map was introduced in aafee23, but wasn't properly filled.
This mainly adjusts many locations, that expected strings instead of
integers or boolean.
add_pg_decoders is moved after setup of the StatementPool, because
execute_and_clear could potentially make use of it.

Add `config.active_record.warn_on_result_set_size` option
|

| |
| |
| |
| |
| |
| |
| |
| | |
When set to an integer, a warning will be logged whenever a result set
larger than the specified size is returned by a query. Fixes #16463
The warning is outputed a module which is prepended in an initializer,
so there will be no performance impact if
`config.active_record.warn_on_records_fetched_greater_than` is not set.

the newer method used for discriminating new records did not
use the older and more robust method used for instantiating
existing records, but did have a better post-check to ensure
the sublass was in the hierarchy. so move the descendants check
to find_sti_class, and then simply call find_sti_class from
subclass_from_attributes

Fix referencing wrong aliases while joining tables of has many through association

association
While joining table of has_many :through association, ActiveRecord will
use the actual table name instead of through-join alias. It results with
a wrong SQL and exception is raised. This only happens when calculation
methods like #count is called.
This issue is affecting Rails 4.1.x and 4.2.x as well.

This is obviously all very internal, but sometimes you have to look at
it... and when you do, it'll save a lot of confusion if it doesn't lie
about its identity.

The subtype will (quite reasonably) ignore the possibility that it has
`changed_in_place?` by becoming nil.

The code in the comment fails on concurrent inserts if done inside a transaction.
The fix is to force a savepoint to run so that if the database raises an unique violation exception. Otherwise, you'll get errors like:
```
(0.3ms) BEGIN
Cart Load (0.5ms) SELECT "carts".* FROM "carts" WHERE "carts"."uuid" = '12345' LIMIT 1
# Another process inserts a cart with uuid of '12345' right now
SQL (4371.7ms) INSERT INTO "carts" ("created_at", "updated_at", "uuid") VALUES ('2015-03-21 01:05:07.833231', '2015-03-21 01:05:07.833231', '12345') RETURNING "id" [["created_at", Sat, 21 Mar 2015 01:05:07 PDT -07:00], ["updated_at", Sat, 21 Mar 2015 01:05:07 PDT -07:00], ["uuid", "12345"]]

As described here https://github.com/rails/rails/issues/19420. When
using the Postgres BigInt[] field type the big int value was not being
translated into schema.rb. This caused the field to become just a
regular integer field when building off of schema.rb. This fix will
address this by delegating the limit from the subtype to the Array type.

This is a better test for 51660f0. It is testing that the SQL is the
same before and after the previously leaky scope is called. Before if
`hotel.drink_designers` was called first then `hotel.recipes` would
incorrectly get the scope applied. We want to be sure that the
polymorphic hm:t association is not leaking into or affecting the
SQL for the hm:t association on `Hotel`.
The reason I couldn't do this before was because there was an issue with
the SQL getting cached and wanted to resolve that later and then fix the
test to be better. Because of the caching, this test requires that
`Hotel.reflect_on_association(:recipes).clear_association_scope_cache`
be called after the first call to `hotel.recipes` to clear the
assocation scope chain and not interfere with the rest of the test.

In the tests if I were to call `post.categorizations.to_a` and then later call
`post.categorizations.to_a` expecting to have different results the 2 queries
would be the same because of the caching involved in
`@association_scope_cache`. The chain gets cached and the queries will
be the same even if they are not supposed to be (i.e. testing an order
dependent scoping issue).
I found this issue because I was working on a bug with cached scoped
in hm:t and hm:t polymorphic relationships but `capture_sql` was
outputting the wrong SQL to write a good test.

present from the start.
When a new record has the necessary information prior to save, we can
avoid busting the cache.
We could simply clear the @proxy on #reset or #reset_scope, but that
would clear the cache more often than necessary.

It is redundant with tests in `eager_loading?`, but for the difference
between `includes_values.present?` and `includes_values.any?`, which
is a difference without a distinction because `false` has no meaning
for `includes`.
