* Stop relying on columns in sqlite quoting testsSean Griffin2015-01-012-22/+7
| | | | | | The string encoding test wasn't using the types for anything. The boolean casting test included logic that should be in the tests for the types, and the string test was legitimately not testing anything useful.

| | | | | | | | | | | | This error only happens when the foreign key is missing. Before this fix the following exception was being raised: NoMethodError: undefined method `val' for #<Arel::Nodes::BindParam:0x007fc64d19c218> Now the message is: ActiveRecord::UnknownAttributeError: unknown attribute 'foreign_key' for Model.

| | | | | | | | | | | | | | | | | | | | This showed up when running BinaryTest#test_load_save with the more restrictive input string handling of pg-0.18.0.pre20141117110243.gem . Bytea values sent to the server are in binary format, but are returned back as escaped text. To fulfill the assumption that type_cast_from_database(type_cast_for_database(binary)) == binary we unescape only, if the value was really received from the server.
* | Ensures that primary_key method will return nil when multi-pkArthur Neves2014-12-303-0/+18
| | | | | | | | | | | | | | When table has a composite primary key, the `primary_key` method for sqlite3 and postgresql was only returning the first field of the key. Ensures that it will return nil instead, as AR dont support composite pks.

* | Remove all cases of manuallly wrapping `Arel::Nodes::Quoted`Sean Griffin2014-12-293-12/+10
| | | | | | | | | | | | | | | | | | | | This is no longer required now that we are injecting a type caster object into the Arel table, with the exception of uniqueness validations. Since it calls `ConnectionAdapter#type_cast`, the value has already been cast for the database. We don't want Arel to attempt to cast it further, so we need to continue wrapping it in a quoted node. This can potentially go away when this validator is refactored to make better use of `where` or the predicate builder.

* 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.

* 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.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 Griffin2014-12-221-1/+23
| | | | | | | | 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
* Don't wrap `create_table` in a transaction for tests which run on MySQLSean Griffin2014-12-221-3/+1

* 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]

| | | | | | | | Apparently PG does not validate against RFC 4122. The intent of the original patch is just to protect against PG errors (which potentially breaks txns, etc) because of bad user input, so we shouldn't try any harder than PG itself. Closes #17931

* `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
