Moves the configs_for and DatabaseConfig struct into it's own file. I was considering doing this in a future refactoring but our set up forced me to move it now. You see there are `mattr_accessor`'s on the Core module that have default settings. For example the `schema_format` defaults to Ruby. So if I call `configs_for` or any methods in the Core module it will reset the `schema_format` to `:ruby`. By moving it to it's own class we can keep the logic contained and avoid this unfortunate issue. The second change here does a double loop over the yaml files. Bear with me... Our tests dictate that we need to load an environment before our rake tasks because we could have something in an environment that the database.yml depends on. There are side-effects to this and I think there's a deeper bug that needs to be fixed but that's for another issue. The gist of the problem is when I was creating the dynamic rake tasks if the yaml that that rake task is calling evaluates code (like erb) that calls the environment configs the code will blow up because the environment is not loaded yet. To avoid this issue we added a new method that simply loads the yaml and does not evaluate the erb or anything in it. We then use that yaml to create the task name. Inside the task name we can then call `load_config` and load the real config to actually call the code internal to the task. I admit, this is gross, but refactoring can't all be pretty all the time and I'm working hard with `@tenderlove` to refactor much more of this code to get to a better place re connection management and rake tasks.

Adds the ability to dump the schema or structure files for mulitple databases. Loops through the configs for a given env and sets a filename based on the format, then establishes a connection for that config and dumps into the file.

`each_current_configuration` is used by create, drop, and other methods to find the configs for a given environment and returning those to the method calling them. The change here allows for the database commands to operate on all the configs in the environment. Previously we couldn't slice the hashes and iterate over them becasue they could be two tier or could be three tier. By using the database config structs we don't need to care whether we're dealing with a three tier or two tier, we can just parse all the configs based on the environment. This makes it possible for us to run `bin/rails db:create` and it will create all the configs for the dev and test environment ust like it does for a two tier - it creates the db for dev and test. Now `db:create` will create `primary` for dev and test, and `animals` for dev and test if our database.yml looks like: ``` development: primary: etc animals: etc test: primary: etc animals: etc ``` This means that `bin/rails db:create`, `bin/rails db:drop`, and `bin/rails db:migrate` will operate on the dev and test env for both primary and animals ds.

If we have a three-tier yaml file like this: ``` development: primary: database: "development" animals: database: "development_animals" migrations_paths: "db/animals_migrate" ``` This will add db create/drop/and migrate tasks for each level of the config under that environment. ``` bin/rails db:drop:primary bin/rails db:drop:animals bin/rails db:create:primary bin/rails db:create:animals bin/rails db:migrate:primary bin/rails db:migrate:animals ```

Passing around and parsing hashes is easy if you know that it's a two tier config and each key will be named after the environment and each value will be the config for that environment key. This falls apart pretty quickly with three-tier configs. We have no idea what the second tier will be named (we know the first is primary but we don't know the second), we have no easy way of figuring out how deep a hash we have without iterating over it, and we'd have to do this a lot throughout the code since it breaks all of Active Record's assumptions regarding configurations. These methods allow us to pass around objects instead. This will allow us to more easily parse the configs for the rake tasks. Evenually I'd like to replace the Active Record connection management that passes around config hashes to use these methods as well but that's much farther down the road. `walk_configs` takes an environment, specification name, and a config and turns them into DatabaseConfig struct objects so we can ask the configs questions like: ``` db_config.spec_name => animals db_config.env_name => development db_config.config { :adapter => mysql etc } ``` `db_configs` loops through all given configurations and returns an array of DatabaseConfig structs for each config in the yaml file. and lastly `configs_for` takes an environment and either returns the spec name and config if a block is given or returns an array of DatabaseConfig structs just for the given environment.

The current documentation explicitly mentions only PostgreSQL (hstore/json) for use with `.store_accessor`, making it somewhat confusing what to choose on a MySQL 5.7+ setup (which introduced a json data type).

If you had a three-tier config, the `establish_connection` that's called in the Railtie on load can't figure out how to access the default configuration. This is because Rails assumes that the config is the first value in the hash and always associated with the key from the environment. With a three tier config however we need to go one level deeper. This commit includes 2 changes. 1) removes a line from `resolve_all` which was parsing out the the environment from the config so instead of getting ``` { :development => { :primary => { :database => "whatever" } }, :animals => { :database => "whatever-animals" } }, etc with test / prod } ``` We'd instead end up with a config that had no attachment to it's envioronment. ``` { :primary => { :database => "whatever" } :animals => { :database => "whatever-animals" } etc - without test and prod } ``` Not only did this mean that Active Record didn't know how to establish a connection, it didn't have the other necessary configs along with it in the configs list. So fix this I removed the line that deletes these configs. The second thing this commit changes is adding this line to `establish_connection` ``` spec = spec[spec_name.to_sym] if spec[spec_name.to_sym] ``` When you have a three-tier config and don't pass any hash/symbol/env etc to `establish_connection` the resolver will automatically return both the primary and secondary (in this case animals db) configurations. We'll get an `database configuration does not specify adapter` error because AR will try to establish a connection on the `primary` key rather than the `primary` key's config. It assumes that the `development` or default env automatically will return a config hash, but with a three-tier config we actually get a key and config `primary => config`. This fix is a bit of a bandaid because it's not the "correct" way to handle this situation, but it does solve our immediate problem. The new code here is saying "if the config returned from the resolver (I know it's called spec in here but we interchange our meanings a LOT and what is returned is a three-tier config) has a key matching the "primary" spec name, grab the config from the spec and pass that to the estalbish_connection method". This works because if we pass `:animals` or a hash, or `:primary` we'll already have the correct configuration to connect with. This fixes the case where we want Rail to connect with the default connection. Coming soon is a refactoring that should eliminate the need to do this but I need this fix in order to write the multi-db rake tasks that I promised in my RailsConf submission. `@tenderlove` and I are working on the refactoring of the internals for connection management but it won't be ready for a few weeks and this issue has been blocking progress.

In #24542, quoted_time was introduced to strip the leading date component for time columns because it was having a significant effect in mariadb. However, it assumed that the date component was always 2000-01-01 which isn't the case, especially if the source wasn't another time column.
-
由 Andrew White 提交于
For legacy reasons Rails stores time columns on sqlite as full timestamp strings. However because the date component wasn't being normalized this meant that when they were read back they were being prefixed with 2001-01-01 by ActiveModel::Type::Time. This had a twofold result - first it meant that the fast code path wasn't being used because the string was invalid and second it was corrupting the second fractional component being read by the Date._parse code path. Fix this by a combination of normalizing the timestamps on writing and also changing Active Model to be more lenient when detecting whether a string starts with a date component before creating the dummy time value for parsing.

When a class has a belongs_to or has_one relationship with dependent: :destroy option enabled, objects of this class should not be deleted if it's dependents cannot be deleted. Example: class Parent has_one :child, dependent: :destroy end class Child belongs_to :parent, inverse_of: :child before_destroy { throw :abort } end c = Child.create p = Parent.create(child: c) p.destroy p.destroyed? # expected: false; actual: true; Fixes #32022

This issue is caused by `@_trigger_update_callback` won't be updated due to `_update_record` in `Locking::Optimistic` doesn't call `super` when optimistic locking is enabled. Now optimistic locking concern when updating is supported by `_update_row` low level API, therefore overriding `_update_record` is no longer necessary. Removing the method just fix the issue. Closes #29096. Closes #29321. Closes #30823.

Currently primary key value can not be updated if a record has a locking column because of `_update_record` in `Locking::Optimistic` doesn't respect `id_in_database` as primary key value unlike in `Persistence`. And also, if a record has dirty primary key value, it may destroy any other record by the lock version of dirty record itself. When updating/destroying persisted records, it should identify themselves by `id_in_database`, not by dirty primary key value.

This reverts ignoring polymorphic error introduced at 02da8aea. What the ignoring want to solve was caused by force eager loading regardless of whether it is necessary, but it has been fixed by #29043. The ignoring is now only causing a mismatch of `exists?` behavior with `to_a`, `count`, etc. It should behave consistently.

This is an alternative of #29722, and follow up of #32048. This does not change the current behavior, but makes it easier to modify all polymorphic names consistently.

Actually `reflection.klass` should be valid AR model unless `polymorphic?`. Previously it worked limitedly by ignoring `NameError` even if `reflection.klass` is invalid, and our isolated testing depends on the limited working. Probably we should also check the klass validity in `check_validity!` properly. Until that time, I restored the error suppression for now. Closes #32113.

Currently the place where we limit what gets sent to the database is in the implementation for `partial_writes`. We should also be restricting it to column names when partial writes are turned off. Note that we're using `&` instead of just defaulting to `self.class.column_names`, as the instance version of `attribute_names` does not include attributes which are uninitialized (were not included in the select clause)

This is an alternative of #29722, and revert of #29601 and a1fcbd97. Currently, association creation and normal association finding doesn't respect `store_full_sti_class`. But eager loading and preloading respect the setting. This means that if set `store_full_sti_class = false` (`true` by default), eager loading and preloading can not find created polymorphic records. Association creation and finding should work consistently.
