| * Only define attribute methods from schema cacheEugene Kenny2018-09-281-1/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | To define the attribute methods for a model, Active Record needs to know the schema of the underlying table, which is usually achieved by making a request to the database. This is undesirable behaviour while the app is booting, for two reasons: it makes the boot process dependent on the availability of the database, and it means every new process will make one query for each table, which can cause issues for large applications. However, if the application is using the schema cache dump feature, then the schema cache already contains the necessary information, and we can define the attribute methods without causing any extra database queries.

* | Enable `Style/RedundantBegin` cop to avoid newly adding redundant begin blockRyuta Kamizono2018-12-213-48/+40
| | | | | | | | | | | | | | | | | | | | Currently we sometimes find a redundant begin block in code review (e.g. https://github.com/rails/rails/pull/33604#discussion_r209784205). I'd like to enable `Style/RedundantBegin` cop to avoid that, since rescue/else/ensure are allowed inside do/end blocks in Ruby 2.5 (https://bugs.ruby-lang.org/issues/12906), so we'd probably meets with that situation than before.

* | Introduce a guard against DNS rebinding attacksGenadi Samokovarov2018-12-151-6/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ActionDispatch::HostAuthorization is a new middleware that prevent against DNS rebinding and other Host header attacks. By default it is included only in the development environment with the following configuration: Rails.application.config.hosts = [ IPAddr.new("0.0.0.0/0"), # All IPv4 addresses. IPAddr.new("::/0"), # All IPv6 addresses. "localhost" # The localhost reserved domain. ] In other environments, `Rails.application.config.hosts` is empty and no Host header checks will be done. If you want to guard against header attacks on production, you have to manually permit the allowed hosts with: Rails.application.config.hosts << "product.com" The host of a request is checked against the hosts entries with the case operator (#===), which lets hosts support entries of type RegExp, Proc and IPAddr to name a few. Here is an example with a regexp. # Allow requests from subdomains like `www.product.com` and # `beta1.product.com`. Rails.application.config.hosts << /.*\.product\.com/ A special case is supported that allows you to permit all sub-domains: # Allow requests from subdomains like `www.product.com` and # `beta1.product.com`. Rails.application.config.hosts << ".product.com"

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes `test_scaffold_tests_pass_by_default` test fails in CI. https://travis-ci.org/rails/rails/jobs/457621750#L2095-L2120 It seems `manifest.json` was broken. `webpacker` will compile automatically if packs is not compiled. If parallel test is enabled, it seems that this compilation process is executed simultaneously in multiple processes, and it may become an inconsistent state. In order to avoid this, compile before running the test.
* | | Correctly handle unknown object in parallel testsyuuji.yaginuma2018-11-171-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DRb wraps in `DRbUnknown` if the data contains a type that can not be resolved locally. This can happen if an error occurs in the test and the error class can not be resolved on the server side. When this happens, an instance of `DRbUnknown` is passed to the `result` of `Server#record`. This causes another error(undefined method assertions for #<DRb::DRbUnknown:> (NoMethodError)) in `reporter.record`. This can confirm by the following steps. ``` $ rails new app -B --dev; cd app $ rails g scaffold user name:string $ edit `config.action_controller.allow_forgery_protection = true` in environments/test.rb $ bin/rails t ``` In the case of `DRbUnknown` occurs, can't resolve error exception. So wrap exception with `DRbRemoteError` in the same way as an unmarshalled object.

* Eagerly define attribute methods in productionEugene Kenny2018-09-241-0/+47
| | | | | | | | | | | | | The attribute methods for a model are currently defined lazily the first time that model is instantiated, even when `config.eager_load` is true. This means the first request to use each model incurs the cost, which usually involves a database round trip to fetch the schema definition. By defining the attribute methods for all models while the application is booting, we move that work out of any individual request. When using a forking web server, this also reduces the number of times the schema definition is queried by doing it once in the parent process instead of from each forked process during their first request.
* Make sure this test check the issue solved in #31135Rafael Mendonça França2018-09-221-6/+12
| | | | | | | | | | | | | | | Before this change this test was passing even if we revert #31135. The reason for that is that `app 'development'` will load the environment in the test process and it is happening before db_create_and_drop is called. This was not asserting that the environment was loaded in the db:create task itself. To test it we enhance the db:create task with a block that writes to a tmp file the value of the config. If the environment is loaded before that task enhancement runs the content of the file will have "true" insteand of "false".

| | | | | | | | | | | | | | does not support it If you are using the "in cache versioning" also known as "recyclable cache keys" the cache store must be aware of this scheme, otherwise you will generate cache entries that never invalidate. This PR adds a check to the initialization process to ensure that if recyclable cache keys are being used via ``` config.active_record.cache_versioning = true ``` Then the cache store needs to show that it supports this versioning scheme. Cache stores can let Rails know that they support this scheme by adding a method `supports_in_cache_versioning?` and returning true.

* Fix query cache to load before first requestEileen Uchitelle2018-09-121-0/+33
| | | | | | | | | | | | | | | | In a test app we observed that the query cache was not enabled on the first request. This was because the query cache hooks are installed on load and active record is loaded in the middle of the first request. If we remove the `on_load` from the railtie the query cache hooks will be installed before the first request, allowing the cache to be enabled on that first request. This is ok because query cache doesn't load anything else, only itself so we're not eager loading all of active record before the first request, just the query cache hooks. [Eileen M. Uchitelle & Matthew Draper]

* Respect config setting when output deprecation notice in rake tasksyuuji.yaginuma2018-09-044-1/+4
| | | | | | | | | The rake tasks which became deprecate now does not load the environment. Therefore, even if the application specifies the behavior of deprecating, the message is output to stderr ignoring the specification. It seems that this is not the expected behavior.

* Convert configs_for to kwargs, add include_replicasEileen Uchitelle2018-08-311-7/+10
| | | | | | | | | | | Changes the `configs_for` method from using traditional arguments to using kwargs. This is so I can add the `include_replicas` kwarg without having to always include `env_name` and `spec_name` in the method call. `include_replicas` defaults to false because everywhere internally in Rails we don't want replicas. `configs_for` is for iterating over configurations to create / run rake tasks, so we really don't ever need replicas in that case.
* Refactors Active Record connection managementEileen Uchitelle2018-08-301-10/+10

A three-tier config means that when Rails needed to choose a default configuration (in the case a user doesn't ask for a specific configuration) it wasn't clear to Rails which the default was. I [bandaid fixed this so the rake tasks could work](#32271) but that fix wasn't correct because it actually doubled up the configuration hashes. Instead of attemping to manipulate the hashes @tenderlove and I decided that it made more sense if we converted the hashes to objects so we can easily ask those object questions. In a three tier config like this: ``` development: primary: database: "my_primary_db" animals: database; "my_animals_db" ``` We end up with an object like this: ``` @configurations=[ #<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbded10 @env_name="development",@spec_name="primary", @config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}>, #<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbdea90 @env_name="development",@spec_name="animals", @config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}> ]> ``` The configurations setter takes the database configuration set by your application and turns them into an `ActiveRecord::DatabaseConfigurations` object that has one getter - `@configurations` which is an array of all the database objects. The configurations getter returns this object by default since it acts like a hash in most of the cases we need. For example if you need to access the default `development` database we can simply request it as we did before: ``` ActiveRecord::Base.configurations["development"] ``` This will return primary development database configuration hash: ``` { "database" => "my_primary_db" } ``` Internally all of Active Record has been converted to use the new objects. I've built this to be backwards compatible but allow for accessing the hash if needed for a deprecation period. To get the original hash instead of the object you can either add `to_h` on the configurations call or pass `legacy: true` to `configurations. ``` ActiveRecord::Base.configurations.to_h => { "development => { "database" => "my_primary_db" } } ActiveRecord::Base.configurations(legacy: true) => { "development => { "database" => "my_primary_db" } } ``` The new configurations object allows us to iterate over the Active Record configurations without losing the known environment or specification name for that configuration. You can also select all the configs for an env or env and spec. With this we can always ask any object what environment it belongs to: ``` db_configs = ActiveRecord::Base.configurations.configurations_for("development") => #<ActiveRecord::DatabaseConfigurations:0x00007fd1acbdf800 @configurations=[ #<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbded10 @env_name="development",@spec_name="primary", @config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}>, #<ActiveRecord::DatabaseConfigurations::HashConfig:0x00007fd1acbdea90 @env_name="development",@spec_name="animals", @config={"adapter"=>"sqlite3", "database"=>"db/development.sqlite3"}> ]> db_config.env_name => "development" db_config.spec_name => "primary" db_config.config => { "adapter"=>"sqlite3", "database"=>"db/development.sqlite3" } ``` The configurations object is more flexible than the configurations hash and will allow us to build on top of the connection management in order to add support for primary/replica connections, sharding, and constructing queries for associations that live in multiple databases.
