* Avoid redundant `time.getutc` call if it is already utc time objectRyuta Kamizono2019-06-181-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently `type.serialize` and `connection.{quote|type_cast}` for a time object always does `time.getutc` call regardless of whether it is already utc time object or not, that duplicated proccess (`connection.type_cast(type.serialize(time))`) allocates extra/useless time objects for each type casting. This avoids that redundant `time.getutc` call if it is already utc time object. In the case of a model has timestamps (`created_at` and `updated_at`), it avoids 6,000 time objects allocation for 1,000 times `model.save`. ```ruby ObjectSpace::AllocationTracer.setup(%i{path line type}) pp ObjectSpace::AllocationTracer.trace { 1_000.times { User.create } }.select { |k, _| k[0].end_with?("quoting.rb", "time_value.rb") } ``` Before (c104bfe424e6cebe9c8e85a38515327a6c88b1f8): ``` {["~/rails/activerecord/lib/active_record/connection_adapters/abstract/quoting.rb", 203, :T_ARRAY]=>[1004, 0, 778, 0, 1, 0], ["~/rails/activerecord/lib/active_record/connection_adapters/abstract/quoting.rb", 220, :T_STRING]=>[2, 0, 2, 1, 1, 0], ["~/rails/activerecord/lib/active_record/connection_adapters/abstract/quoting.rb", 209, :T_ARRAY]=>[8, 0, 8, 1, 1, 0], ["~/rails/activerecord/lib/active_record/connection_adapters/abstract/quoting.rb", 57, :T_ARRAY]=>[4, 0, 4, 1, 1, 0], ["~/rails/activemodel/lib/active_model/type/helpers/time_value.rb", 17, :T_DATA]=>[4000, 0, 3096, 0, 1, 0], ["~/rails/activerecord/lib/active_record/connection_adapters/abstract/quoting.rb", 120, :T_DATA]=>[2000, 0, 1548, 0, 1, 0], ["~/rails/activerecord/lib/active_record/connection_adapters/abstract/quoting.rb", 126, :T_STRING]=>[4000, 0, 3096, 0, 1, 0]} ``` After (this change): ``` {["~/rails/activerecord/lib/active_record/connection_adapters/abstract/quoting.rb", 203, :T_ARRAY]=>[1004, 0, 823, 0, 1, 0], ["~/rails/activerecord/lib/active_record/connection_adapters/abstract/quoting.rb", 220, :T_STRING]=>[2, 0, 2, 1, 1, 0], ["~/rails/activerecord/lib/active_record/connection_adapters/abstract/quoting.rb", 209, :T_ARRAY]=>[8, 0, 8, 1, 1, 0], ["~/rails/activerecord/lib/active_record/connection_adapters/abstract/quoting.rb", 57, :T_ARRAY]=>[4, 0, 4, 1, 1, 0], ["~/rails/activerecord/lib/active_record/connection_adapters/abstract/quoting.rb", 126, :T_STRING]=>[2000, 0, 1638, 0, 1, 0]} ```

* Move while_preventing_writes from conn to handlereileencodes2019-06-142-15/+17
| | | | | | | | | | | | | | | | | If we put the `while_preventing_writes` on the connection then the middleware that sends reads to the primary and ensures they can't write will not work. The `while_preventing_writes` will only be applied to the connection which it's called on - which in the case of the middleware is Ar::Base. This worked fine if you called it directly like `OtherDbConn.connection.while_preventing_writes` but Rails didn't have a way of knowing you wanted to call it on all the connections. The change here moves the `while_preventing_writes` method from the connection to the handler so that it can block writes to all queries for that handler. This will apply to all the connections associated with that handler.
* Move SchemaMigration to migration_contexteileencodes2019-06-142-5/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | This PR moves the `schema_migration` to `migration_context` so that we can access the `schema_migration` per connection. This does not change behavior of the SchemaMigration if you are using one database. This also does not change behavior of any public APIs. `Migrator` is private as is `MigrationContext` so we can change these as needed. We now need to pass a `schema_migration` to `Migrator` so that we can run migrations on the right connection outside the context of a rake task. The bugs this fixes were discovered while debugging the issues around the SchemaCache on initialization with multiple database. It was clear that `get_all_versions` wouldn't work without these changes outside the context of a rake task (because in the rake task we establish a connection and change AR::Base.connection to the db we're running on). Because the `SchemaCache` relies on the `SchemaMigration` information we need to make sure we store it per-connection rather than on ActiveRecord::Base. [Eileen M. Uchitelle & Aaron Patterson]

* Make ActiveRecord `ConnectionPool.connections` thread-safe. (#36473)jeffdoering2019-06-131-1/+16
| | | | | | | | | | | | | | | | | | | | | | | * 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]

* Allow column name with function (e.g. `length(title)`) as safe SQL stringRyuta Kamizono2019-06-104-8/+32
| | | | | | | | | | | | | | | | 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.

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 pooleileencodes2019-06-054-5/+33
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Use WeakRef to avoid leaking connection poolsJohn Hawthorn2019-05-271-11/+21
| | | | | | | | | | | | | | | | | | Prior to 3e2e8eeb9ea552bd4782538cf9348455f3d0e14a the Reaper thread would hold a reference to connection pools indefinitely, preventing the connection pool from being garbage collected, and also leaking the Thread. Since 3e2e8eeb9ea552bd4782538cf9348455f3d0e14a, there is only one Reaper Thread for all pools, however all pools are still stored in a class variable, preventing them from being garbage collected. This commit instead holds reference to the pools through a WeakRef. This way, connection pools referenced elsewhere will be reaped, any others will be able to be garbage collected. I don't love resorting to WeakRef to solve this, but I believe it's the simplest way to accomplish the the desired behaviour.

| | | | | | | | | | | | | | | | | | | | | | transaction Currently, `committed!`/`rolledback!` will only be attempted for the first enrolled record in the transaction, that will cause some problematic behaviors. 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.
