* Use advisory locks to prevent concurrent migrationsSam Davies2015-10-301-0/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

* Closes rails/rails#18864: Renaming transactional fixtures to transactional testsBrandon Weiss2015-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I’m renaming all instances of `use_transcational_fixtures` to `use_transactional_tests` and “transactional fixtures” to “transactional tests”. I’m deprecating `use_transactional_fixtures=`. So anyone who is explicitly setting this will get a warning telling them to use `use_transactional_tests=` instead. I’m maintaining backwards compatibility—both forms will work. `use_transactional_tests` will check to see if `use_transactional_fixtures` is set and use that, otherwise it will use itself. But because `use_transactional_tests` is a class attribute (created with `class_attribute`) this requires a little bit of hoop jumping. The writer method that `class_attribute` generates defines a new reader method that return the value being set. Which means we can’t set the default of `true` using `use_transactional_tests=` as was done previously because that won’t take into account anyone using `use_transactional_fixtures`. Instead I defined the reader method manually and it checks `use_transactional_fixtures`. If it was set then it should be used, otherwise it should return the default, which is `true`. If someone uses `use_transactional_tests=` then it will overwrite the backwards-compatible method with whatever they set.
* Error message testing fixFranky W2015-02-201-1/+3
| | | | | | | | | The testing of error messages have been implemented wrongly a few times. This is an attempt to fix it. For example, some of these test should have failed with the new code. The reason they are not failling with the new string is the fact they were not being tested beforehand.
* pg tests, be clear about the missing type that causes a test skip.Yves Senn2015-02-121-8/+2

* tests, remove unused requires.Yves Senn2015-02-121-1/+0
| | | | | | "active_support/testing/stream" is already required in `test_case.rb`. Furthermore the test "test/cases/migration_test.rb" could no longer be executed directly.
* Allow a symbol to be passed to `attribute`, in place of a type objectSean Griffin2015-02-061-2/+2
| | | | | | | | | | | | | | | | | | The same is not true of `define_attribute`, which is meant to be the low level no-magic API that sits underneath. The differences between the two APIs are: - `attribute` - Lazy (the attribute will be defined after the schema has loaded) - Allows either a type object or a symbol - `define_attribute` - Runs immediately (might get trampled by schema loading) - Requires a type object This was the last blocker in terms of public interface requirements originally discussed for this feature back in May. All the implementation blockers have been cleared, so this feature is probably ready for release (pending one more look-over by me).

* | Attribute assignment and type casting has nothing to do with columnsSean Griffin2015-01-311-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's finally finished!!!!!!! The reason the Attributes API was kept private in 4.2 was due to some publicly visible implementation details. It was previously implemented by overloading `columns` and `columns_hash`, to make them return column objects which were modified with the attribute information. This meant that those methods LIED! We didn't change the database schema. We changed the attribute information on the class. That is wrong! It should be the other way around, where schema loading just calls the attributes API for you. And now it does! Yes, this means that there is nothing that happens in automatic schema loading that you couldn't manually do yourself. (There's still some funky cases where we hit the connection adapter that I need to handle, before we can turn off automatic schema detection entirely.) There were a few weird test failures caused by this that had to be fixed. The main source came from the fact that the attribute methods are now defined in terms of `attribute_names`, which has a clause like `return [] unless table_exists?`. I don't *think* this is an issue, since the only place this caused failures were in a fake adapter which didn't override `table_exists?`. Additionally, there were a few cases where tests were failing because a migration was run, but the model was not reloaded. I'm not sure why these started failing from this change, I might need to clear an additional cache in `reload_schema_from_cache`. Again, since this is not normal usage, and it's expected that `reset_column_information` will be called after the table is modified, I don't think it's a problem. Still, test failures that were unrelated to the change are worrying, and I need to dig into them further. Finally, I spent a lot of time debugging issues with the mutex used in `define_attribute_methods`. I think we can just remove that method entirely, and define the attribute methods *manually* in the call to `define_attribute`, which would simplify the code *tremendously*. Ok. now to make this damn thing public, and work on moving it up to Active Model.

* Treat strings greater than int max value as out of rangeSean Griffin2014-10-311-1/+0
| | | | | | | | | | | Sufficiently large integers cause `find` and `find_by` to raise `StatementInvalid` instead of `RecordNotFound` or just returning `nil`. Given that we can't cast to `nil` for `Integer` like we would with junk data for other types, we raise a `RangeError` instead, and rescue in places where it would be highly unexpected to get an exception from casting.

| * Correctly determine if migration is needed.Jeremy McNevin2014-08-131-0/+15
| | | | | | | | | | | | | | This method would assume that if last migration in the migrations directory matched the current schema version, that the database was up to date, but this does not account for new migrations with older timestamps that may be pending.
* | Change the default `null` value for timestampsSean Griffin2014-08-121-1/+1
|/ | | | | | | As per discussion, this changes the model generators to specify `null: false` for timestamp columns. A warning is now emitted if `timestamps` is called without a `null` option specified, so we can safely change the behavior when no option is specified in Rails 5.
* build fix, remove not null constraint.Yves Senn2014-07-221-1/+1
| | | | | | | | | | | The fixtures are still in play, adding a new column without a default and `null: true` is not possible. This reverts back to leaking global state, as our `schema.rb` adds the `null: false` constraint on this field. A future solution would be to make the `migration_test.rb` run independent of fixture tables. This way we can simply drop the state after test execution, without worrying about side effects. /cc @zuhao

| | | | | | | If we want to have type decorators mess with the attribute, but not the column, we need to stop type casting on the column. Where possible, we changed the tests to test the value of `column_defaults`, which is public API. `Column#default` is not.

| | | | | | | | | | | The options will specify the prefix and the suffix. Also, I'm moving the method to be an instance method on the +Migration+ instance. This makes more sense than being a class method on the +Migrator+ class because the only place that uses it is on a +Migration+ instance (in a method_missing hook). The logic for the Migrator shouldn't be doing any work to calculate the table name, it should be the Migration itself. Also made some small indentation fixes.
