* Inform Arel that we don't need to cast a value in testsSean Griffin2014-12-261-2/+4
| | | | | | | Part of the larger refactoring to remove type casting from Arel. We can inform it that we already have the right type by wrapping the value in an `Arel::Nodes::Quoted`. This commit can be reverted when we have removed type casting from Arel in Rail 5.1
* Go through normal `where` logic when preloading associationsSean Griffin2014-12-264-4/+4
| | | | | | | | | | This will allow eager type casting to take place as needed. There doesn't seem to be any particular reason that the `in` statement was forced for single values, and the commit message where it was introduced gives no context. See https://github.com/rails/rails/commit/d90b4e2615e8048fdeffc6dffe3246704adee01f
* Eagerly cast array values passed to the predicate builderSean Griffin2014-12-261-2/+6

* Perform casting of single values within the predicate builderSean Griffin2014-12-261-1/+1
| | | | | | | | | | | As part of the larger refactoring to remove type casting from Arel, we need to do the casting of values eagerly. The predicate builder is the closest place that knows about the Active Record class, and can therefore have the type information. /cc @mrgilman [Sean Griffin & Melanie Gilman]
* Remove `klass` and `arel_table` as a dependency of `PredicateBuilder`Sean Griffin2014-12-261-1/+2
| | | | | | | | | | | | | | | This class cares far too much about the internals of other parts of Active Record. This is an attempt to break out a meaningful object which represents the needs of the predicate builder. I'm not fully satisfied with the name, but the general concept is an object which represents a table, the associations to/from that table, and the types associated with it. Many of these exist at the `ActiveRecord::Base` class level, not as properties of the table itself, hence the need for another object. Currently it provides these by holding a reference to the class, but that will likely change in the future. This allows the predicate builder to remain wholy concerned with building predicates. /cc @mrgilman

* Change `PredicateBuilder` handler methods to instance methodsSean Griffin2014-12-261-1/+3
| | | | | | | | | | | | This will allow us to pass the predicate builder into the constructor of these handlers. The procs had to be changed to objects, because the `PredicateBuilder` needs to be marshalable. If we ever decide to make `register_handler` part of the public API, we should come up with a better solution which allows procs. /cc @mrgilman [Sean Griffin & Melanie Gilman]
* Inject the `PredicateBuilder` into the `Relation` instanceSean Griffin2014-12-263-27/+28
| | | | | | | Construction of relations can be a hotspot, we don't want to create one of these in the constructor. This also allows us to do more expensive things in the predicate builder's constructor, since it's created once per AR::Base subclass

|\ | | | | Fix connection leak when a thread checks in additional connections.
| * Fix connection leak when a thread checks in additional connections.Matt Jones2014-12-231-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code in `ConnectionPool#release` assumed that a single thread only ever holds a single connection, and thus that releasing a connection only requires the owning thread_id. There is a trivial counterexample to this assumption: code that checks out additional connections from the pool in the same thread. For instance: connection_1 = ActiveRecord::Base.connection connection_2 = ActiveRecord::Base.connection_pool.checkout ActiveRecord::Base.connection_pool.checkin(connection_2) connection_3 = ActiveRecord::Base.connection At this point, connection_1 has been removed from the `@reserved_connections` hash, causing a NEW connection to be returned as connection_3 and the loss of any tracking info on connection_1. As long as the thread in this example lives, connection_1 will be inaccessible and un-reapable. If this block of code runs more times than the size of the connection pool in a single thread, every subsequent connection attempt will timeout, as all of the available connections have been leaked.

* / Fixing numeric attrs when set to same negative valueDaniel Fox2014-12-232-0/+10
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This bug occurs when an attribute of an ActiveRecord model is an ActiveRecord::Type::Integer type or a ActiveRecord::Type::Decimal type (or any other type that includes the ActiveRecord::Type::Numeric module. When the value of the attribute is negative and is set to the same negative value, it is marked as changed. Take the following example of a Person model with the integer attribute age: class Person < ActiveRecord::Base # age :integer(4) end The following will produce the error: person = Person.new(age: -1) person.age = -1 person.changes => { "age" => [-1, -1] } person.age_changed? => true The problematic line is here: module ActiveRecord module Type module Numeric ... def non_numeric_string?(value) # 'wibble'.to_i will give zero, we want to make sure # that we aren't marking int zero to string zero as # changed. value.to_s !~ /\A\d+\.?\d*\z/ end end end end The regex match doesn't accept numbers with a leading '-'.
* Don't perform statement caching for `find` when called from a scopeSean Griffin2014-12-222-1/+31
| | | | | | | | If there is a method defined such as `find_and_do_stuff(id)`, which then gets called on an association, we will perform statement caching and the parent ID will not change on subsequent calls. Fixes #18117
* Don't calculate all in-place changes to determine if attribute_changed?Sean Griffin2014-12-221-0/+15
| | | | | | | | | Calling `changed_attributes` will ultimately check if every mutable attribute has changed in place. Since this gets called whenever an attribute is assigned, it's extremely slow. Instead, we can avoid this calculation until we actually need it. Fixes #18029

* Add `foreign_key` as an option to `references` for `change_table`Sean Griffin2014-12-221-0/+43
| | | | | | | | | | | This has the same comments as 9af90ffa00ba35bdee888e3e1ab775ba0bdbe72c, however it affects the `add_reference` method, and `t.references` in the context of a `change_table` block. There is a lot of duplication of code between creating and updating tables. We should re-evaluate the structure of this code from a high level so changes like this don't need to be made in two places. (Note to self)
* Add a `foreign_key` option to `references` while creating the tableSean Griffin2014-12-221-0/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than having to do: create_table :posts do |t| t.references :user end add_foreign_key :posts, :users You can instead do: create_table :posts do |t| t.references :user, foreign_key: true end Similar to the `index` option, you can also pass a hash. This will be passed as the options to `add_foreign_key`. e.g.: create_table :posts do |t| t.references :user, foreign_key: { primary_key: :other_id } end is equivalent to create_table :posts do |t| t.references :user end add_foreign_key :posts, :users, primary_key: :other_id
* Add `force: true` to table created in testsSean Griffin2014-12-221-1/+1
| | | | | | If the test is interrupted in a way that the teardown block fails to run, the tests will fail to run until the table is removed manually without this option.
* Correctly handle limit on int4 and int8 types in PGSean Griffin2014-12-221-0/+25
| | | | | | | | | | | | | | | | PG doesn't register it's types using the `int(4)` format that others do. As such, if we alias `int8` to the other integer types, the range information is lost. This is fixed by simply registering it separately. The other option (which I specifically chose to avoid) is to pass the information of the original type that was being aliased as an argument. I'd rather avoid that, since an alias should truly be treated the same. If we need different behavior for a different type, we should explicitly register it with that, and not have a conditional based on aliasing. Fixes #18144 [Sean Griffin & ysbaddaden]

* `update_column` take ruby-land input, not database-land inputSean Griffin2014-12-161-2/+4
| | | | | | | | | | | | | | | In the case of serialized columns, we would expect the unserialized value as input, not the serialized value. The original issue which made this distinction, #14163, introduced a bug. If you passed serialized input to the method, it would double serialize when it was sent to the database. You would see the wrong input upon reloading, or get an error if you had a specific type on the serialized column. To put it another way, `update_column` is a special case of `update_all`, which would take `['a']` and not `['a'].to_yaml`, but you would not pass data from `params` to it. Fixes #18037

* | Allow custom handling of non-standard types in `time_zone_conversion`Sean Griffin2014-12-081-0/+6
|/ | | | | | | | | | | | PostgreSQL for example, allows infinity as a valid value for date time columns. The PG type has explicit handling for that case. However, time zone conversion will end up trampling that handling. Unfortunately, we can't call super and then convert time zones. However, if we get back nil from `.in_time_zone`, it's something we didn't expect so we can let the superclass handle it. Fixes #17971
* Don't error when `attributes` is called on a frozen AR modelSean Griffin2014-12-081-0/+8
| | | | | | | | | | | | | | | | | | `freeze` will ultimately end up freezing the `AttributeSet`, which in turn freezes its `@attributes` hash. However, we actually insert a special object to lazily instantiate the values of the hash on demand. When it does need to actually instantiate all of them for iteration (the only case is `ActiveRecord::Base#attributes`, which calls `AttributeSet#to_h`), it will set an instance variable as a performance optimization Since it's just an optimization for subsequent calls, and that method being called at all is a very uncommon case, we can just leave the ivar alone if we're frozen, as opposed to coming up with some overly complicated mechanism for freezing which allows us to continue to modify ourselves. Fixes #17960
* Revert to 4.1 behavior for casting PG arraysSean Griffin2014-12-081-5/+20
| | | | | | | | | | The user is able to pass PG string literals in 4.1, and have it converted to an array. This is also possible in 4.2, but it would remain in string form until saving and reloading, which breaks our `attr = save.reload.attr` contract. I think we should deprecate this in 5.0, and only allow array input from user sources. However, this currently constitutes a breaking change to public API that did not go through a deprecation cycle.
* Make error message clearer that :on requires a symbol, not a stringCarol Nichols2014-12-071-0/+4
| | | | | | | | | | | | | | The validation added in 5a3dc8092d19c816b0b1203945639cb91d065847 will reject values for the `:on` option for after_commit and after_rollback callbacks that are string values like `"create"`. However, the error message says ":on conditions for after_commit and after_rollback callbacks have to be one of create,destroy,update". That looks like a string value *would* be valid. This commit changes the error message to say ":on conditions for after_commit and after_rollback callbacks have to be one of [:create, :destroy, :update]", making it clearer that symbols are required.

* Correctly respect subtypes for PG arrays and rangesSean Griffin2014-12-051-0/+18
| | | | | | | | | | | | | The type registration was simply looking for the OID, and eagerly fetching/constructing the sub type when it was registered. However, numeric types have additional parameters which are extracted from the actual SQL string of the type during lookup, and can have their behavior change based on the result. We simply need to use the block form of registration, and look up the subtype lazily instead. Fixes #17935

|/ | | | | | | | | Active Record defines `attribute_method_suffix :?`. That suffix will match any predicate method when the lookup occurs in Active Model. This will make it incorrectly decide that `id_changed?` should not exist, because it attempts to determine if the attribute `id_changed` is present, rather than `id` with the `_changed?` suffix. Instead, we will look for any correct match.
