|/ | | | This ends up adding it to all save-related callbacks defined in `ActiveRecord::DefineCallbacks`, including e.g. `after_create`. Which should be fine: they didn't support `:on` in the first place.
* Replace permissive Mocha expectationsutilum2018-07-222-32/+86
| | | | | | | | | | | | | | | | | | | | | | | | | Step 6 in #33162 When using Mocha like this: `ActiveRecord::Base.expects(:establish_connection).with(some_args)`, the expectations created look something like this: ``` @expectations= [#<Expectation:0x561350d968e0 expected exactly once, not yet invoked: ActiveRecord::Base.establish_connection("adapter" => "mysql2", "database" => nil) >, #<Expectation:0x561350dab8f8 allowed any number of times, not yet invoked: ActiveRecord::Base.establish_connection(any_parameters) >, #<Expectation:0x561350dc30c0 allowed any number of times, not yet invoked: ActiveRecord::Base.connection(any_parameters) >] ``` Minitest mocking (and the way we use it in `MethodCallAssertions`) expressly refuses to facilitate such permissiive expectations, insisting that all calls be specified in the actual expected order. This patch replaces such calls to `Mocha#expects` with `ActiveSupport::Testing::MethodCallAssertions` and specifies all expected calls in the epxected order.

| * Avoid extra scoping in delegating to klass methods in the `scope` blockRyuta Kamizono2018-07-191-0/+5
| | | | | | | | | | | | | | | | | | | | Since #29301, delegating to klass methods in the `scope` block would cause extra scoping by the receiver itself. The extra scoping would always override intermediate scoping like `unscoped` and caused the regression #33387. To keep the original scoping behavior, should avoid the extra scoping in the `scope` block. Fixes #33387.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Related #31201. If creating custom primary key (like a string) in SQLite, it would also create an internal index implicitly which named begin with "sqlite_". It need to be hidden since the internal object names are reserved and prohibited for public use. See https://www.sqlite.org/fileformat2.html#intschema Fixes #33320.

|/ | | | | | | | | | | | | | | | The TIME, DATETIME, and TIMESTAMP types [have supported](https://mariadb.com/kb/en/library/microseconds-in-mariadb/) a fractional seconds precision from 0 to 6. Default values from time columns with specified precision is read as `current_timestamp(n)` from information schema. rake `db:schema:dump` produces `schema.rb` **without** default values for time columns with the specified precision: t.datetime "last_message_at", precision: 6, null: false rake `db:schema:dump` produces `schema.rb` **with** default values for time columns with the specified precision: t.datetime "last_message_at", precision: 6, default: -> { "current_timestamp(6)" }, null: false
* Don't share seen object cache between different join nodes in eager loadingRyuta Kamizono2018-07-031-0/+18
| | | | | | | | | | | Currently, the seen object cache is shared if join nodes have the same target class. But it is a wrong assumption, we can't share the seen object cache between different join nodes (e.g. `:readonly_account` and `:accounts` have the same target class `Account`, but the instances have the different state `readonly`). Fixes #26805. Closes #27737.

|\ | | | | | | Support readonly option in SQLite3Adapter
| * Support readonly option in SQLite3AdapterCarl Brasic2018-07-021-0/+33
|/ | | | | | | | | | | | | | | | | Readonly sqlite database files are very useful as a data format for storing configuration/lookup data that is too complicated for YAML files. But since such files would typically be committed to a source control repository, it's important to ensure that they are truly safe from being inadvertently modified. Unfortunately using unix permissions isn't enough, as sqlite will "helpfully" add the write bit to a database file whenever it's written to. sqlite3-ruby has supported a `:readonly` option since version 1.3.2 (see https://github.com/sparklemotion/sqlite3-ruby/commit/c20c9f5dd2990042) This simply passes that option through to the adapter if present in the config hash. I think this is best considered an adapter-specific option since no other supported database has an identical concept.

| * Call initialize after allocateAaron Patterson2018-06-261-13/+0
| | | | | | | | | | | | | | | | If someone calls allocate on the object, they'd better also call an initialization routine too (you can't expect allocate to do any initialization work). Before this commit, AR objects that are instantiated from the database would call `define_attribute_methods` twice.
* | Speed up homogeneous AR lists / reduce allocationsAaron Patterson2018-06-251-0/+5
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit speeds up allocating homogeneous lists of AR objects. We can know if the result set contains an STI column before initializing every AR object, so this change pulls the "does this result set contain an STI column?" test up, then uses a specialized instantiation function. This way we only have to check for an STI column once rather than N times. This change also introduces a new initialization function that is meant for use when allocating AR objects that come from the database. Doing this allows us to eliminate one hash allocation per AR instance. Here is a benchmark: ```ruby require 'active_record' require 'benchmark/ips' ActiveRecord::Base.establish_connection adapter: "sqlite3", database: ":memory:" ActiveRecord::Migration.verbose = false ActiveRecord::Schema.define do create_table :users, force: true do |t| t.string :name t.timestamps null: false end end class User < ActiveRecord::Base; end 2000.times do User.create!(name: "Gorby") end Benchmark.ips do |x| x.report("find") do User.limit(2000).to_a end end ``` Results: Before: ``` [aaron@TC activerecord (master)]$ be ruby -I lib:~/git/allocation_tracer/lib speed.rb Warming up -------------------------------------- find 5.000 i/100ms Calculating ------------------------------------- find 56.192 (± 3.6%) i/s - 285.000 in 5.080940s ``` After: ``` [aaron@TC activerecord (homogeneous-allocation)]$ be ruby -I lib:~/git/allocation_tracer/lib speed.rb Warming up -------------------------------------- find 7.000 i/100ms Calculating ------------------------------------- find 72.204 (± 2.8%) i/s - 364.000 in 5.044592s ```

* | Ensure to calculate column aliases after all table aliases are constructedRyuta Kamizono2018-06-191-2/+44
|/ | | | | | | | | | | | | | | | | Currently, column aliases which is used for eager loading are calculated before constructing all table aliases in FROM clause. `JoinDependency#join_constraints` constructs table aliases for `joins` first, and then always re-constructs table aliases for eager loading. If both `joins` and eager loading are given a same table association, the re-construction would cause the discrepancy between column aliases and table aliases. To avoid the discrepancy, the column aliases should be calculated after all table aliases are constructed. Fixes #30603.
* Fix `touch` option to behave consistently with `Persistence#touch` methodRyuta Kamizono2018-06-183-25/+63
| | | | | | | | | | | | | | | | `touch` option was added to `increment!` (#27660) and `update_counters` (#26995). But that option behaves inconsistently with `Persistence#touch` method. If `touch` option is passed attribute names, it won't update update_at/on attributes unlike `Persistence#touch` method. Due to changed from `Persistence#touch` to `increment!` with `touch` option, #31405 has a regression that `counter_cache` with `touch` option which is passed attribute names won't update update_at/on attributes. I think that the inconsistency is not intended. To get back consistency, ensure that `touch` option updates update_at/on attributes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This may seem like an unnecessary refactoring but some apps want / need to configure the information passed to the query cache logger. In order to do that we can add a method here that can be easily overridden by the app itself, rather than hacking the query cache logger to include that information. To override apps can call ``` def cache_notifications_info super.merge(connected_host: "hostname") end ``` This will take what's already in the query cache logger and add `@something="yea"` to the object. At GitHub we use this to log the number of queries that are cached, the connection host and the connection url.

* | Fix GROUP BY queries to apply LIMIT/OFFSET after aggregationsRyuta Kamizono2018-06-071-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If `eager_loading` is true, `apply_join_dependency` force applies LIMIT/OFFSET before JOINs by `limited_ids_for` to keep parent records count. But for aggregation queries, LIMIT/OFFSET should be applied after aggregations the same as SQL semantics. And also, we could not replace SELECT list by `limited_ids_for` when a query has a GROUP BY clause. It had never been worked since it will causes generating invalid SQL for MySQL, PostgreSQL, and probably most backends. ``` % ARCONN=postgresql be ruby -w -Itest test/cases/calculations_test.rb -n test_group_by_with_limit Using postgresql Run options: -n test_group_by_with_limit --seed 20925 # Running: E Error: CalculationsTest#test_group_by_with_limit: ActiveRecord::StatementInvalid: PG::GroupingError: ERROR: column "posts.id" must appear in the GROUP BY clause or be used in an aggregate function LINE 1: SELECT DISTINCT "posts"."id", "posts"."type" AS alias_0 FRO... ^ : SELECT DISTINCT "posts"."id", "posts"."type" AS alias_0 FROM "posts" LEFT OUTER JOIN "comments" ON "comments"."post_id" = "posts"."id" GROUP BY "posts"."type" ORDER BY "posts"."type" ASC LIMIT $1 ``` Fixes #8103. Closes #27249.
* | Fix `collection.create` to could be rolled back by `after_save`Ryuta Kamizono2018-06-071-0/+11
| | | | | | | | | | | | | | | | | | | | | | In `_create_record`, explicit `transaction` block requires rollback handling manually when `insert_record` is failed. We need to handle it in `_create_record`, not in `insert_record`, since our test cases expect a record added to target and returned even if `insert_record` is failed, Closes #31488.
