* Always add records to parent of nested transactionEugene Kenny2018-11-072-1/+12
| | | | | | | | | | | | | | | | | | | When a record with transactional callbacks is saved, it's attached to the current transaction so that the callbacks can be run when the transaction is committed. Records can also be added manually with `add_transaction_record`, even if they have no transactional callbacks. When a nested transaction is committed, its records are transferred to the parent transaction, as transactional callbacks should only be run when the outermost transaction is committed (the "real" transaction). However, this currently only happens when the record has transactional callbacks, and not when added manually with `add_transaction_record`. If a record is added to a nested transaction, we should always attach it to the parent transaction when the nested transaction is committed, regardless of whether it has any transactional callbacks.

* Fix inspect with non-primary key id attributeEugene Kenny2018-11-065-3/+26
| | | | | | | | | | | The `read_attribute` method always returns the primary key when asked to read the `id` attribute, even if the primary key isn't named `id`, and even if another attribute named `id` exists. For the `inspect`, `attribute_for_inspect` and `pretty_print` methods, this behaviour is undesirable, as they're used to examine the internal state of the record. By using `_read_attribute` instead, we'll get the real value of the `id` attribute.

* Don't pass useless `table_name` to `ModelMetadata.new`Ryuta Kamizono2018-11-033-13/+4

| | | | | | | | | | The `@connection` is no longer used since ee5ab22. Originally the `@connection` was useless because it is only used in `timestamp_column_names`, which is only used if `model_class` is given. If `model_class` is given, the `@connection` is always `model_class.connection`.

* `update_columns` raises if the column is unknownSean Griffin2018-10-303-4/+15
| | | | | | | | | Previosly, `update_columns` would just take whatever keys you gave it and tried to run the update query. Most likely this would result in an error from the database. However, if the column actually did exist, but was in `ignored_columns`, this would result in the method returning successfully when it should have raised, and an attribute that should not exist written to `@attributes`.

| * Avoid violating key constraints in fixture HABTM associationsJames Le Cuirot2018-10-292-0/+7
| | | | | | | | | | | | | | | | | | When loading fixtures, Ruby 1.9's hash key ordering means that HABTM join table rows are always loaded before the parent table rows, violating foreign key constraints that may be in place. This very simple change ensures that the parent table's key appears first in the hash. Violations may still occur if fixtures are loaded in the wrong order but those instances can be avoided unlike this one.

* | Ignore empty condition on #construct_relation_for_existsr7kamura2018-10-272-1/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | At https://github.com/rails/rails/commit/fc0e3354af7e7878bdd905a95ce4c1491113af9a, ```rb relation = relation.where(conditions) ``` was rewritten to: ```rb relation.where!(condition) ``` This change accidentally changed the result of `Topic.exists?({})` from true to false. To fix this regression, first I moved the blank check logic (`opts.blank?`) from `#where` to `#where!`, because I thought `#where!` should be identical to `#where`, except that instead of returning a new relation, it adds the condition to the existing relation. But on second thought after some discussion on https://github.com/rails/rails/pull/34329, I started to think that just fixing `#construct_relation_for_exists` is more preferable than changing `#where` and `#where!`.

Since changes in the method were reverted and as mentioned in the comment https://github.com/rails/rails/pull/31819#discussion_r221847481 that titles of the tests added in #31819 don't reflect implementation I think we can remove those test for now.
* | | `assert_called_with` should require `args` argumentbogdanvlviv2018-10-251-1/+1

I found this bug by working on [minitest-mock_expectations](https://github.com/bogdanvlviv/minitest-mock_expectations) gem. This gem is an extension for minitest that provides almost the same method call assertions. I was wondering whether you would consider adding "minitest-mock_expectations" to `rails/rails` instead of private `ActiveSupport::Testing::MethodCallAssertions` module. If yes, I'll send a patch - https://github.com/bogdanvlviv/rails/commit/a970ecc42c3a9637947599f2c13e3762e4b59208

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since #33844, eager loading/preloading with too many and/or too large ids won't be broken by pre-checking whether the value is constructable or not. But the pre-checking caused the type to be evaluated at relation build time instead of at the query execution time, that is breaking an expectation for some apps. I've made the pre-cheking lazy as much as possible, that is no longer happend at relation build time.

* | Reduce string allocations in read/write_attributeEugene Kenny2018-10-212-8/+6
| | | | | | | | | | | | | | | | | | When `attr_name` is passed as a symbol, it's currently converted to a string by `attribute_alias?`, and potentially also `attribute_alias`, as well as by the `read_attribute`/`write_attribute` method itself. By converting `attr_name` to a string up front, the extra allocations related to attribute aliases can be avoided.

| * | ActiveRecord#respond_to? No longer allocates stringsschneems2018-10-153-12/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an alternative to https://github.com/rails/rails/pull/34195 The active record `respond_to?` method needs to do two things if `super` does not say that the method exists. It has to see if the "name" being passed in represents a column in the table. If it does then it needs to pass it to `has_attribute?` to see if the key exists in the current object. The reason why this is slow is that `has_attribute?` needs a string and most (almost all) objects passed in are symbols. The only time we need to allocate a string in this method is if the column does exist in the database, and since these are a limited number of strings (since column names are a finite set) then we can pre-generate all of them and use the same string. We generate a list hash of column names and convert them to symbols, and store the value as the string name. This allows us to both check if the "name" exists as a column, but also provides us with a string object we can use for the `has_attribute?` call. I then ran the test suite and found there was only one case where we're intentionally passing in a string and changed it to a symbol. (However there are tests where we are using a string key, but they don't ship with rails). As re-written this method should never allocate unless the user passes in a string key, which is fairly uncommon with `respond_to?`. This also eliminates the need to special case every common item that might come through the method via the `case` that was originally added in https://github.com/rails/rails/commit/f80aa5994603e684e3fecd3f53bfbf242c73a107 (by me) and then with an attempt to extend in https://github.com/rails/rails/pull/34195. As a bonus this reduces 6,300 comparisons (in the CodeTriage app homepage) to 450 as we also no longer need to loop through the column array to check for an `include?`.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | `init_with` and `init_from_db` are almost the same code except decode `coder`. And also, named `init_from_db` is a little misreading, a raw values hash from the database is already converted to an attributes object by `attributes_builder.build_from_database`, so passed `attributes` in that method is just an attributes object. I renamed that method to `init_with_attributes` since the method is shared with `init_with` to initialize an empty model object.
