* Make ActiveRecord `ConnectionPool.connections` thread-safe. (#36473)jeffdoering2019-06-131-0/+22
| | | | | | | | | | | | | | | | | | | | | | | * Make ActiveRecord `ConnectionPool.connections` thread-safe. ConnectionPool documentation is clear on the need to synchronize access to @connections but also states that public methods do not require synchronization. Existing code exposed @connections directly via attr_reader. The fix uses synchronize() to lock @connections then returns a copy to the caller using Array.dup(). Includes comments on the connections method that thread-safe access to the connections array does not imply thread-safety of accessing methods on the actual connections. Adds a test-case that modifies the pool using a supported method in one thread while a second thread accesses pool.connections. The test fails without this patch. Fixes #36465. * Update activerecord/test/cases/connection_pool_test.rb [jeffdoering + Rafael Mendonça França]

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, almost all "Dangerous query method" warnings are false alarm. As long as almost all the warnings are false alarm, developers think "Let's ignore the warnings by using `Arel.sql()`, it actually is false alarm in practice.", so I think we should effort to reduce false alarm in order to make the warnings valuable. This allows column name with function (e.g. `length(title)`) as safe SQL string, which is very common false alarm pattern, even in the our codebase. Related 6c82b6c99, 6607ecb2a, #36420. Fixes #32995.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently `posts.title` is regarded as a safe SQL string, but `"posts"."title"` (it is a result of `quote_table_name("posts.title")`) is regarded as an unsafe SQL string even though a result of `quote_table_name` should obviously be regarded as a safe SQL string, since the column name matcher doesn't respect quotation, it is a little annoying. This changes the column name matcher to allow quoted identifiers as safe SQL string, now all results of the `quote_table_name` are regarded as safe SQL string.
* | | Move schema cache from connection to pooleileencodes2019-06-051-1/+0
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR proposes moving the schema cache from the connection to the pool so the connection can ask the pool for the cache. In a future PR our goal is to be able to read the yaml file from the pool so we can get rid of the `active_record.check_schema_cache_dump` initializer. This will fix the issues surrounding dumping the schema cache and mulitple databases. Why do we want to get rid of the initializer you ask? Well I was looking at #34449 and trying to make it work for our usecase and it revealed A LOT of problems. There are a few issues that I will fix in remaining PRs with SchemaMigration, but there's a big glaring issue with this initializer. When you have an application with multiple databases we'll need to loop through all the configurations and set the schema cache on those connections. The problem is on initialization we only have one connection - the one for Ar::Base. This is fine in a single db application but not fine in multi-db. If we follow the pattern in #34449 and establish a connection to those other dbs we will end up setting the cache on the _connection object_ rather than on all connections that connect for that config. So even though we looped through the configs and assigned the cache the cache will not be set (or will be set wrong) once the app is booted because the connection objects after boot are _different_ than the connection objects we assigned the cache to. After trying many different ways to set the schema cache `@tenderlove` and I came to the conclusion that the initializer is problematic, as is setting the schema cache twice. This is part 1 to move the cache to the pool so the cache can read from the schema cache yaml file instead of setting it when initializing the app. To do this we have created a `NullPool` that initializes an empty cache. I put the `get_schema_cache` and `set_schema_cache` in an `AbstractPool` so we can share code between `ConnectionPool` and `NullPool` instead of duplicating code. Now we only need to set the schema_cache on the pool rather than the connection. In `discard!` we need to unset the connection from the schema_cache - we still want the cache just not the connection.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When someone has a multi-db application their `ApplicationRecord` will look like: ```ruby class ApplicationRecord < ActiveRecord::Base self.abstract_class = true connects_to database: { writing: :primary, reading: :replica } end ``` This will cause us to open 2 connections to ActiveRecord::Base's database when we actually only want 1. This is because Rails sees `ApplicationRecord` and thinks it's a new connection, not the existing `ActiveRecord::Base` connection because the `connection_specification_name` is different. This PR changes `ApplicationRecord` classes to consider themselves the same as the "primary" connection. Fixes #36382

The first one problem, `clear_transaction_record_state` won't be called even if the transaction is finalized except the first enrolled record. This means that de-duplicated records in the transaction won't refer latest state (e.g. won't happen rolling back record state). The second one problem, the enrolled order is not always the same as the order in which the actions actually happened, the first enrolled record may succeed no actions (e.g. `destroy` has already succeeded on another record during `before_destroy`), it will lose to fire any transactional callbacks. To avoid both problems, we should attempt `committed!`/`rolledback!` to all enrolled records in the transaction.

I think the main concerns of these tests are how each database adapter creates or drops indexes then ignoring `SHOW KEYS FROM` statement makes sense. https://github.com/rails/rails/blob/fef174f5c524edacbcad846d68400e7fe114a15a/activerecord/lib/active_record/connection_adapters/mysql/schema_statements.rb#L11 ```ruby execute_and_free("SHOW KEYS FROM #{quote_table_name(table_name)}", "SCHEMA") do |result| ``` * Temporary change not included in this commit to show which statements executed ```diff $ git diff diff --git a/activerecord/test/cases/migration_test.rb b/activerecord/test/cases/migration_test.rb index 8e8ed494d9..df05f9bd16 100644 --- a/activerecord/test/cases/migration_test.rb +++ b/activerecord/test/cases/migration_test.rb @@ -854,7 +854,7 @@ def test_adding_indexes classname = ActiveRecord::Base.connection.class.name[/[^:]*$/] expected_query_count = { - "Mysql2Adapter" => 3, # Adding an index fires a query every time to check if an index already exists or not + "Mysql2Adapter" => 1, # Adding an index fires a query every time to check if an index already exists or not "PostgreSQLAdapter" => 2, }.fetch(classname) { raise "need an expected query count for #{classname}" @@ -886,7 +886,7 @@ def test_removing_index classname = ActiveRecord::Base.connection.class.name[/[^:]*$/] expected_query_count = { - "Mysql2Adapter" => 3, # Adding an index fires a query every time to check if an index already exists or not + "Mysql2Adapter" => 1, # Adding an index fires a query every time to check if an index already exists or not "PostgreSQLAdapter" => 2, }.fetch(classname) { raise "need an expected query count for #{classname}" $ ``` * Executed these modified tests ```ruby $ ARCONN=mysql2 bin/test test/cases/migration_test.rb -n /index/ Using mysql2 Run options: -n /index/ --seed 8462 F Failure: BulkAlterTableMigrationsTest#test_adding_indexes [/home/yahonda/git/rails/activerecord/test/cases/migration_test.rb:863]: 3 instead of 1 queries were executed.

* Should take the record's state of first action in the transactionRyuta Kamizono2019-04-301-0/+2
| | | | | | | | | | | | | | | | If the same id's records are saved and/or destroyed in the transaction, commit callbackes will only run for the first enrolled record. https://github.com/rails/rails/blob/a023e2180093ebc517a642aaf21f3c7241c67657/activerecord/lib/active_record/connection_adapters/abstract/transaction.rb#L115-L119 The regression #36132 is caused due to #35920 changed the enrollment order that the first action's record will be enrolled to last in the transaction. We could not change the the enrollment order as long as someone depends on the enrollment order. Fixes #36132.
* Fix merging left_joins to maintain its own `join_type` contextRyuta Kamizono2019-04-272-0/+5
| | | | | | | | | | | | | | | This fixes a regression for #35864. Usually, stashed joins (mainly eager loading) are performed as LEFT JOINs. But the case of merging joins/left_joins of different class, that (stashed) joins are performed as the same `join_type` as the parent context for now. Since #35864, both (joins/left_joins) stashed joins might be contained in `joins_values`, so each stashed joins should maintain its own `join_type` context. Fixes #36103.
