* Improve AR connection fork safetyMatthew Draper2017-11-181-0/+32
| | | | | | Use whatever adapter-provided means we have available to ensure forked children don't send quit/shutdown/goodbye messages to the server on connections that belonged to their parent.

| | * 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 `name` from `establish_connection`Arthur Neves2016-05-242-8/+7
| | | | | Instead of passing a separete name variable, we can make the resolver merge a name on the config, and use that before creating the Specification.
* remove_connection should not remove parent connectionArthur Neves2016-05-111-0/+7
| | | | | | When calling remove_connection in a subclass, that should not fallback to the parent, otherwise it will remove the parent connection from the handler.
* 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.

| * If Rails is not defined, check ENV["RAILS_ENV"] and ENV["RACK_ENV"].Keith Gable2014-10-211-0/+89
| | | | | | | | | | | | | | This fixes a regression introduced by 6cc03675d30b58e28f585720dad14e947a57ff5b. ActiveRecord, if used without Rails, always checks the "default_env" environment. This would be OK, except that Sinatra also supports environments, and it runs with {RACK|RAILS}_ENV=production. This patch adds a fallback to RAILS_ENV and RACK_ENV (and ultimately default_env) if Rails.env doesn't exist.
* | fix MySQL enum type lookup with values matching another type. Closes #17402.Yves Senn2014-10-291-0/+4
|/ | | | | | | | | | The MySQLAdapter type map used the lowest priority for enum types. This was the result of a recent refactoring and lead to some broken lookups for enums with values that match other types. Like `8bit`. This patch restores the priority to what we had before the refactoring. /cc @sgrif
* Deprecate automatic counter caches on has_many :throughSean Griffin2014-06-261-2/+2
| | | | | | | | | | | Reliant on https://github.com/rails/rails/pull/15747 but pulled to a separate PR to reduce noise. `has_many :through` associations have the undocumented behavior of automatically detecting counter caches. However, the way in which it does so is inconsistent with counter caches everywhere else, and doesn't actually work consistently. As with normal `has_many` associations, the user should specify the counter cache on the `belongs_to`, if they'd like it updated.
* Parsing DATABASE_URI, use URI#hostname: it's smarter about IPv6Matthew Draper2014-06-141-0/+12

* Rename `type_cast` to `type_cast_from_database`Sean Griffin2014-06-091-1/+1
| | | | | | | | In some cases there is a difference between the two, we should always be doing one or the other. For convenience, `type_cast` is still a private method on type, so new types that do not need different behavior don't need to implement two methods, but it has been moved to private so it cannot be used accidentally.
