* Don't allocate new strings in compiled attribute methodsJon Leighton2012-10-122-20/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This improves memory and performance without having to use symbols which present DoS problems.

* Revert "Key the attributes hash with symbols"Jon Leighton2012-10-123-12/+8
| | | | | | | | | | | | This reverts commit 86c3dfbd47cb96af02daaa655963292b1a1b110e. Conflicts: activerecord/lib/active_record/attribute_methods/read.rb Reason: whilst this increased performance, it also presents a DoS risk via memory exhaustion if users were allowing user input to dictate the arguments of read/write_attribute. I will investigate alternative ways to cut down on string allocations here.

| * | Fix has_many assocation w/select load after createErnie Miller2012-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you create a new record via a collection association proxy that has not loaded its target, and which selects additional attributes through the association, then when the proxy loads its target, it will inadvertently trigger an ActiveModel::MissingAttributeError during attribute writing when CollectionAssociation#merge_target_lists attempts to do its thing, since the newly loaded records will possess attributes the created record does not. This error also raises a bogus/confusing deprecation warning when accessing the association in Rails 3.2.x, so cherry-pick would be appreciated!
| * | Revert "Use flat_map { } instead of map {}.flatten"Santiago Pastorino2012-10-056-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit abf8de85519141496a6773310964ec03f6106f3f. We should take a deeper look to those cases flat_map doesn't do deep flattening. irb(main):002:0> [[[1,3], [1,2]]].map{|i| i}.flatten => [1, 3, 1, 2] irb(main):003:0> [[[1,3], [1,2]]].flat_map{|i| i} => [[1, 3], [1, 2]]

* | | Rename "Fixtures" class to "FixtureSet"Alexey Muranov2012-10-073-21/+21
| | | | | | | | | | | | Rename `ActiveRecord::Fixtures` class to `ActiveRecord::FixtureSet`. Instances of this class normally hold a collection of fixtures (records) loaded either from a single YAML file, or from a file and a folder with the same name. This change make the class name singular and makes the class easier to distinguish from the modules like `ActiveRecord::TestFixtures`, which operates on multiple fixture sets, or `DelegatingFixtures`, `::Fixtures`, etc., and from the class `ActiveRecord::Fixture`, which corresponds to a single fixture.

* | Count returns 0 without querying if parent is not savedFrancesco Rodriguez2012-10-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patches `CollectionAssociation#count` to return 0 without querying if the parent record is new. Consider the following code: class Account has_many :dossiers end class Dossier belongs_to :account end a = Account.new a.dossiers.build # before patch a.dossiers.count # SELECT COUNT(*) FROM "dossiers" WHERE "dossiers"."account_id" IS NULL # => 0 # after a.dosiers.count # fires without sql query # => 0 Fixes #1856.

* | | Support for partial inserts.Jon Leighton2012-09-287-15/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When inserting new records, only the fields which have been changed from the defaults will actually be included in the INSERT statement. The other fields will be populated by the database. This is more efficient, and also means that it will be safe to remove database columns without getting subsequent errors in running app processes (so long as the code in those processes doesn't contain any references to the removed column).
