| * PostgreSQL, Add input type casts for primitive types.Lars Kanis2015-03-251-0/+10
| | | | | | | | | | | | | | | | | | 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.

| * PostgreSQL, Fix OID based type casts in C for primitive types.Lars Kanis2015-03-253-10/+10
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | 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

* | | Delegate limit to subtypewallerjake2015-03-211-1/+1
|/ / | | | | | | | | | | | | | | | | | | 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. https://github.com/rails/rails/issues/19420

| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | Fix leaky chain on polymorphic associationeileencodes2015-03-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If there was a polymorphic hm:t association with a scope AND second non-scoped hm:t association on a model the polymorphic scope would leak through into the call for the non-polymorhic hm:t association. This would only break if `hotel.drink_designers` was called before `hotel.recipes`. If `hotel.recipes` was called first there would be no problem with the SQL. Before (employable_type should not be here): ``` SELECT COUNT(*) FROM "drink_designers" INNER JOIN "chefs" ON "drink_designers"."id" = "chefs"."employable_id" INNER JOIN "departments" ON "chefs"."department_id" = "departments"."id" WHERE "departments"."hotel_id" = ? AND "chefs"."employable_type" = ? [["hotel_id", 1], ["employable_type", "DrinkDesigner"]] ``` After: ``` SELECT COUNT(*) FROM "recipes" INNER JOIN "chefs" ON "recipes"."chef_id" = "chefs"."id" INNER JOIN "departments" ON "chefs"."department_id" = "departments"."id" WHERE "departments"."hotel_id" = ? [["hotel_id", 1]] ``` From the SQL you can see that `employable_type` was leaking through when calling recipes. The solution is to dup the chain of the polymorphic association so it doesn't get cached. Additionally, this follows `scope_chain` which dup's the `source_reflection`'s `scope_chain`. This required another model/table/relationship because the leak only happens on a hm:t polymorphic that's called before another hm:t on the same model. I am specifically testing the SQL here instead of the number of records becasue the test could pass if there was 1 drink designer recipe for the drink designer chef even though the `employable_type` was leaking through. This needs to specifically check that `employable_type` is not in the SQL statement.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead use .scope_attributes? consistently in ActiveRecord to check whether there are attributes currently associated with the scope. Move the implementation of .scope_attributes? and .scope_attributes to ActiveRecord::Scoping because they don't particularly have to do specifically with Named scopes and their only dependency, in the case of .scope_attributes?, and only caller, in the case of .scope_attributes is contained in Scoping.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces undesirable `Rails.logger` formatters (such as the syslog formatter) onto a `Logger.new(STDERR)` for the console. The production logger may be going elsewhere than standard io, so we can't presume to reuse its formatter. With syslog, this causes missing newlines in the console, so irb prompts start at the end of the last log message. We can work to expose the console formatter in another way to address the original issue.
