| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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"]] PG::UniqueViolation: ERROR: duplicate key value violates unique constraint "carts_uuid_idx1" DETAIL: Key (uuid)=(12345) already exists. : 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" # Retrying the find Cart Load (0.8ms) SELECT "carts".* FROM "carts" WHERE "carts"."uuid" = '12345' LIMIT 1 PG::InFailedSqlTransaction: ERROR: current transaction is aborted, commands ignored until end of transaction block : SELECT "carts".* FROM "carts" WHERE "carts"."uuid" = '12345' LIMIT 1 (0.1ms) ROLLBACK ActiveRecord::StatementInvalid: PG::InFailedSqlTransaction: ERROR: current transaction is aborted, commands ignored until end of transaction block : SELECT "carts".* FROM "carts" WHERE "carts"."uuid" = '12345' LIMIT 1 ```
* | Delegate limit to subtypewallerjake2015-03-214-1/+16
|/ | | | | | | | | | 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

* Improve test for leaky scope chaineileencodes2015-03-181-1/+7
| | | | | | | | | | | | | | | | 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.
* Add `clear_association_scope_cache` methodeileencodes2015-03-181-0/+15
| | | | | | | | | | | | | 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.

* / Closes rails/rails#18864: Renaming transactional fixtures to transactional testsBrandon Weiss2015-03-1651-87/+141
|/ | | | | | | | | | | | | | | | | | | | | | | | | 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 associationeileencodes2015-03-156-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Revert "Merge pull request #15476 from JacobEvelyn/master"Jeremy Kemper2015-03-111-3/+0
| | | | | | | | | | | | | | | | 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. This reverts commit 026ce5ddf11c4cda0aae7f33a9266e54117db318, reversing changes made to 6f0a69c5899ebdc892e2aa23e68e2604fa70fb73.

* Add YAML compatibility for objects from Rails 4.2Sean Griffin2015-03-104-27/+239
| | | | | | | | | | | As of Ruby 2.2, Psych can handle any object which is marshallable. This was not true on previous versions of Ruby, so our delegator types had to provide their own implementation of `init_with` and `encode_with`. Unfortunately, this doesn't match up with what Psych will do today. Since by the time we hit this layer, the objects will have already been created, I think it makes the most sense to just grab the current type from the class.
* Attempt to provide backwards compatible YAML deserializationSean Griffin2015-03-104-0/+76
| | | | | | | | | | | | | | | | | | I should have done this in the first place. We are now serializing an explicit version so we can make more careful changes in the future. This will load Active Record objects which were serialized in Rails 4.1. There will be bugs, as YAML serialization was at least partially broken back then. There will also be edge cases that we might not be able to handle, especially if the type of a column has changed. In addition, we're passing this as `from_database`, since that is required for serialized columns at minimum. All other types were serializing the cast value. At a glance, there should be no types for which this is a problem. Finally, dirty checking information will be lost on records serialized in 4.1, so no columns will be marked as changed.

* Fix intermittent test failuresSean Griffin2015-03-091-0/+1
| | | | | | | | | | The table is being modified in tests, without reloading the column information on the appropriate class. This is leading to incorrect column information in many cases.

* Fix intermittent test failuresSean Griffin2015-03-091-0/+1
| | | | | | | | | | | The default value of `"pg_arrays"."tags"` is being changed to `[]` in one test, but the column information on the model isn't reset after it's changed back. As such, we think the default value is `[]` when in the database it's actually `nil`. That means any test which was assigning `[]` to a new record would have that key skipped with partial writes, as it hasn't changed from the default. However since the *actual* default value is `nil`, we get back values that the test doesn't expect, and it fails.
