* Properly serialize all JSON primitives in the AR JSON typeSean Griffin2016-04-131-5/+12
| | | | | | | | | | | | | | Previously we were assuming that the only valid types for encoding were arrays and hashes. However, any JSON primitive is an accepted value by both PG and MySQL. This does involve a minor breaking change in the handling of `default` in the schema dumper. This is easily worked around, as passing a hash/array literal would have worked fine in previous versions of Rails. However, because of this, I will not be backporting this to 4.2 or earlier. Fixes #24234

* Refactor tz aware types, add support for PG rangesSean Griffin2016-01-081-0/+42
| | | | | | | | | | | | | | | | | This is an alternate implementation to #22875, that generalizes a lot of the logic that type decorators are going to need, in order to have them work with arrays, ranges, etc. The types have the ability to map over a value, with the default implementation being to just yield that given value. Array and Range give more appropriate definitions. This does not automatically make ranges time zone aware, as they need to be added to the `time_zone_aware` types config, but we could certainly make that change if we feel it is appropriate. I do think this would be a breaking change however, and should at least have a deprecation cycle. Closes #22875. /cc @matthewd

| | | | | | | uuid-ossp extension is alreadly enabled on test schema.

* Rename 'key' to 'lock_id' or 'lock_name' for advisory lockingSam Davies2015-11-181-10/+10
| | | | | | | | | - key was a poor choice of name. A key implies something that will unlock a lock. The concept is actually more like a 'lock identifier' - mysql documentation calls this a 'lock name' - postgres documentation calls it a 'lock_id' - Updated variable names to reflect the preferred terminology for the database in question
* Deprecate `#table_exists?`, `#tables` and passing arguments to `#talbes`yui-knk2015-11-092-15/+15
| | | | | | | | | | Reported on #21509, how views is treated by `#tables` are differ by each adapters. To fix this different behavior, after Rails 5.0 is released, deprecate `#tables`. And `#table_exists?` would check both tables and views. To make their behavior consistent with `#tables`, after Rails 5.0 is released, deprecate `#table_exists?`.
* Use advisory locks to prevent concurrent migrationsSam Davies2015-10-301-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Addresses issue #22092 - Works on Postgres and MySQL - Uses advisory locks because of two important properties: 1. The can be obtained outside of the context of a transaction 2. They are automatically released when the session ends, so if a migration process crashed for whatever reason the lock is not left open perpetually - Adds get_advisory_lock and release_advisory_lock methods to database adapters - Attempting to run a migration while another one is in process will raise a ConcurrentMigrationError instead of attempting to run in parallel with undefined behavior. This could be rescued and the migration could exit cleanly instead. Perhaps as a configuration option? Technical Notes ============== The Migrator uses generate_migrator_advisory_lock_key to build the key for the lock. In order to be compatible across multiple adapters there are some constraints on this key. - Postgres limits us to 64 bit signed integers - MySQL advisory locks are server-wide so we have to scope to the database - To fulfil these requirements we use a Migrator salt (a randomly chosen signed integer with max length of 31 bits) that identifies the Rails migration process as the owner of the lock. We multiply this salt with a CRC32 unsigned integer hash of the database name to get a signed 64 bit integer that can also be converted to a string to act as a lock key in MySQL databases. - It is important for subsequent versions of the Migrator to use the same salt, otherwise different versions of the Migrator will not see each other's locks.
* Do not cache prepared statements that are unlikely to have cache hitsSean Griffin2015-10-202-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this commit, Rails makes no differentiation between whether a query uses bind parameters, and whether or not we cache that query as a prepared statement. This leads to the cache populating extremely fast in some cases, with the statements never being reused. In particular, the two problematic cases are `where(foo: [1, 2, 3])` and `where("foo = ?", 1)`. In both cases we'll end up quoting the values rather than using a bind param, causing a cache entry for every value ever used in that query. It was noted that we can probably eventually change `where("foo = ?", 1)` to use a bind param, which would resolve that case. Additionally, on PG we can change our generated query to be `WHERE foo = ANY($1)`, and pass an array for the bind param. I hope to accomplish both in the future. For SQLite and MySQL, we still end up preparing the statements anyway, we just don't cache it. The statement will be cleaned up after it is executed. On postgres, we skip the prepare step entirely, as an API is provided to execute with bind params without preparing the statement. I'm not 100% happy on the way this ended up being structured. I was hoping to use a decorator on the visitor, rather than mixing a module into the object, but the way Arel has it's visitor pattern set up makes it very difficult to extend without inheritance. I'd like to remove the duplication from the various places that are extending it, but that'll require a larger restructuring of that initialization logic. I'm going to take another look at the structure of it soon. This changes the signature of one of the adapter's internals, and will require downstream changes from third party adapters. I'm not too worried about this, as worst case they can simply add the parameter and always ignore it, and just keep their previous behavior. Fixes #21992.

* | introduce `conn.data_source_exists?` and `conn.data_sources`.Yves Senn2015-09-221-0/+2
|/ | | | | | | | | | | | | | | | | 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)
