* [ci skip] Update retrieve_connection_pool commentBenjamin Quorning2016-05-201-7/+1
| | | | | | | | | After PR https://github.com/rails/rails/pull/24844 the documentation for `#retrieve_connection_pool` was out of date. This commit changes: - the reference from `@class_to_pool` to `@owner_to_pool`. - with newer Rubies, `#fetch` isn't significantly slower than `#[]`. Since Rails 5 requires Ruby >= 2.2.2, we can just use `#fetch` here.

| | | | | | | | Ruby 2.4 unifies Fixnum and Bignum into Integer: https://bugs.ruby-lang.org/issues/12005 * Forward compat with new unified Integer class in Ruby 2.4+. * Backward compat with separate Fixnum/Bignum in Ruby 2.2 & 2.3. * Drops needless Fixnum distinction in docs, preferring Integer.

| * | Keep state around for nested calls to #suppressJahfer Husain2016-05-162-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | If a call to #suppress from the same class occurred inside another #suppress block, the suppression state would be set to false before the outer block completes. This change keeps the previous state around in memory and unwinds it as the blocks exit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When `ActiveRecord::Coders::JSON` serialization is used and the default of the column returns `''` it raises the following error: ``` JSON::ParserError: A JSON text must at least contain two octets! ``` If MySQL is running in non-strict mode, it returns an empty string as column default for a text column: ```ruby def extract_default if blob_or_text_column? @default = null || strict ? nil : '' end end ``` Since `''` is invalid JSON, there shouldn't be an attempt to parse it, it should be treated like nil. ActiveRecord::Coders::JSON should behave consistently for all possible non-user-set column default values.

* | | | Fix false positive mutation detection when JSON is used with serializeSean Griffin2016-05-122-1/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When looking for mutation, we compare the serialized version of the value to the before_type_cast form. `Type::Serialized` was breaking this contract by passing the already serialized attribute to the subtype's mutation detection. This never manifested previously, as all mutable subtypes either didn't do anything in their `serialize` method, or had a way to detect double serialization (e.g. `is_a?(String)`). However, now that JSON types can handle string primitives, we need to avoid double serialization. Fixes #24993.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using ActiveRecord::Base.attribute to declare an attribute with a default value on a model where the attribute is not backed by the database would raise a NotImplementedError when model.save is called. The error originates from https://github.com/rails/rails/blob/59d252196b36f6afaafd231756d69ea21537cf5d/activerecord/lib/active_record/attribute.rb#L84. This is called from https://github.com/rails/rails/blob/59d252196b36f6afaafd231756d69ea21537cf5d/activerecord/lib/active_record/attribute.rb#L46 on an ActiveRecord::Attribute::Null object. This commit corrects the behavior by implementing ActiveRecord::Attribute::Null#type_cast. With ActiveRecord::Attribute::Null#type_cast defined, ActiveRecord::Attribute::Null#value (https://github.com/rails/rails/blob/59d252196b36f6afaafd231756d69ea21537cf5d/activerecord/lib/active_record/attribute.rb#L173..L175) can be replaced with its super method (https://github.com/rails/rails/blob/59d252196b36f6afaafd231756d69ea21537cf5d/activerecord/lib/active_record/attribute.rb#L36..L40). fixes #24979

Thats because the parent value could change, and we should keep failling back to the parent. If we cache that in a children as an ivar, we would not fallback anymore in the next call, so the children would not get the new parent spec_name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Follow up of #24844. The key of `@owner_to_pool` was changed from `klass.name` to `spec.name`. By this change "memory leaks in development mode" will not happen, bacause the equality of string is not changed by reloading of model files.

This was the current behavior before rails 5, which will fallback to the parent connection pool. [fixes #24959] Special thanks to @jrafanie for working with me on this fix.

Like that we can decouple the two, and allow the same model to use more than one connection. Historically, folks used to create abstract AR classes on the fly in order to have multiple connections for the same model, and override the connection methods. With this, now we can override the `specificiation_id` method in the model, to return a key, that will be used to find the connection_pool from the handler.

The code as it was written assumed that limit and offset worked as `LIMIT ? OFFSET ?`. Both Oracle and SQL Server have a different syntax, where the offset is stated before the limit. We delegate this behavior to the connection adapter so that these adapters are able to determine how the bind parameters are flattened based on what order their specification has the various clauses appear.
