* Relax assertions in connection config testsDaniel Colson2018-04-201-2/+2
| | | | | | | | | | | | | | | | | | At the moment these two ActiveRecord tests pass with `rake test:sqlite3`, but fail with `ARCONN=sqlite3 bin/test`. `Rails.root` is defined when running `bin/test`, but not when running the rake task. When `Rails.root` is defined, `config[:database]` will look something like `vagrant/rails/activerecord/db/primary.sqlite3` instead of just `db/primary.sqlite3`. (See https://github.com/rails/rails/blob/00caf95e14b90782ab17fbd6d2b930844df99980/activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb#L27) Relaxing `assert_equal` to `assert_match` will allow these tests to pass regardless of how they are run. I do have a question why we need both ways to run tests. I have been using `bin/test` lately, but I see from #32426 that this is not the preferred method.

* Fix connection handling with three-tier configeileencodes2018-03-161-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | * Make `type_map` to private because it is only used in the connection adapterRyuta Kamizono2017-07-202-4/+4
| | | | | | | | | | | | | | | | | | | | | `type_map` is an internal API and it is only used in the connection adapter. And also, some type map initializer methods requires passed `type_map`, but those instances already has `type_map` in itself. So we don't need explicit passing `type_map` to the initializers.

* Fix pool_from_any_process to use most recent speceileencodes2017-01-131-0/+35
| | | | | | | | | | | | | If a process is forked more than once, the pool was grabbing the oldest spec, not the most recent spec. This wasn't noticed before because most folks are lilely forking the process only once. If you're forking the process multiple times however the wrong spec name will be returned and an incorrect connection will be used for the process. This fixes the issue by reversing the list of spec names so we can grab the most recent spec rather than the oldest spec.

* remove_connection should not remove parent connectionArthur Neves2016-05-111-0/+7

* Dont cache the conn_spec_name when emptyArthur Neves2016-05-111-1/+10
| | | | | | | | We cannot cache the connection_specification_name when it doesnt exist. Thats because the parent value could change, and we should keep failling back to the parent. If we cache that in a children as an ivar, we would not fallback anymore in the next call, so the children would not get the new parent spec_name.
* Make sure we reset the connection_specification_name onArthur Neves2016-05-101-0/+14
| | | | | | | | | | | | | | remove_connection When calling `remove_connection` on a model, we delete the pool so we also need to reset the `connection_specification_name` so it will fallback to the parent. This was the current behavior before rails 5, which will fallback to the parent connection pool. [fixes #24959] Special thanks to @jrafanie for working with me on this fix.

* Refactor connection handlerArthur Neves2016-05-053-23/+25
| | | | | | | | | | | | | | | ConnectionHandler will not have any knowlodge of AR models now, it will only know about the specs. Like that we can decouple the two, and allow the same model to use more than one connection. Historically, folks used to create abstract AR classes on the fly in order to have multiple connections for the same model, and override the connection methods. With this, now we can override the `specificiation_id` method in the model, to return a key, that will be used to find the connection_pool from the handler.

* introduce `conn.data_source_exists?` and `conn.data_sources`.Yves Senn2015-09-221-3/+8
| | | | | | | | | | | | | | | | | These new methods are used from the Active Record model layer to determine which relations are viable to back a model. These new methods allow us to change `conn.tables` in the future to only return tables and no views. Same for `conn.table_exists?`. The goal is to provide the following introspection methods on the connection: * `tables` * `table_exists?` * `views` * `view_exists?` * `data_sources` (views + tables) * `data_source_exists?` (views + tables)

* Map :bigint as NUMBER(19) sql_type by using `:limit => 19` for OracleYasuo Honda2015-06-011-1/+5
| | | | | | | | | | | | | | | | | | | since NUMBER(8) is not enough to store the maximum number of bigint. Oracle NUMBER(p,0) as handled as integer because there is no dedicated integer sql data type exist in Oracle database. Also NUMBER(p,s) precision can take up to 38. p means the number of digits, not the byte length. bigint type needs 19 digits as follows. $ irb 2.2.2 :001 > limit = 8 => 8 2.2.2 :002 > maxvalue_of_bigint = 1 << ( limit * 8 - 1) => 9223372036854775808 2.2.2 :003 > puts maxvalue_of_bigint.to_s.length 19 => nil 2.2.2 :004 >
* Add schema cache to new connection pool after forkEugene Kenny2015-05-171-0/+46
| | | | | | | | | | | | | | Active Record detects when the process has forked and automatically creates a new connection pool to avoid sharing file descriptors. If the existing connection pool had a schema cache associated with it, the new pool should copy it to avoid unnecessarily querying the database for its schema. The code to detect that the process has forked is in ConnectionHandler, but the existing test for it was in the ConnectionManagement test file. I moved it to the right place while I was writing the new test for this change.
