| | | | | | | | | | | | | | ActiveRecord's Reflection was refactored by f8d2899d12d59360f29c5eb6a1b1a8fe4ec82ca0 . Top of ancestors chain was changed to `AbstractReflection` from `MacroReflection`, and new Reflections were added.

| | | | | | | | | | | | | | | | | | | | This reverts commit 99801c6a7b69eb4b006a55de17ada78f3a0fa4c1. Ultimately it doesn't matter whether `add_index` or `t.index` are used in the schema dumper in any meaningful way. There are gems out there which hook into the old behavior for things like indexing materialized views. Since the reverted commit doesn't seem to add much benefit, there's no reason for us to break these gems.
* | Remove the assumption of schema in DATABASE_URLJeremy Baker2016-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If you set the DATABASE_URL environment variable to `mydatabase` by accident, you end up getting a series of errors that are hard to trace. For example: ``` warning: already initialized constant ActiveRecord::Base::OrmAdapter ``` Turns out the cascade of errors is due to the error raised by `.tr` being called on `nil`. This commit makes sure that `scheme` is set before calling `.tr` on it. My previous iteration used `@uri.scheme.try(:tr, '-', '_')` but using the `&&` logical operator is a fair bit faster: http://stackoverflow.com/questions/26655032/try-vs-performance With this change, the error message becomes much more understandable: ``` FATAL: database "mydatabase" does not exist (ActiveRecord::NoDatabaseError) ```

* | | | Avoid infinite recursion when bad values are passed to tz aware fieldsSean Griffin2016-02-021-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We had previously updated this to attempt to map over whatever was passed in, so that additional types like range and array could benefit from this behavior without the time zone converter having to deal with every known type. However, the default behavior of a type is to just yield the given value to `map`, which means that if we don't actually know how to handle a value, we'll just recurse infinitely. Since both uses of `map` in this case occur in cases where we know receiving the same object will recurse, we can just break on reference equality. Fixes #23241.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit f6db31ec16e42ee7713029f7120f0b011d1ddc6c. Reason: Scope names can very easily conflict, particularly when sharing Concerns within the team, or using multiple gems that extend AR models. It is true that Ruby has the ability to detect this with the -w option, but the reality is that we are depending on too many gems that do not care about Ruby warnings, therefore it might not be a realistic solution to turn this switch on in our real-world apps.

This manifests as missing `after_commit` callbacks and broken ROLLBACKs. This happens because `before_commit` callbacks fire before the current transaction is popped from the stack, but the exception-handling path they hit assumes that the current transaction was already popped. So the database ROLLBACK is issued, but the transaction stack is left intact. Common cause: deadlocked `#touch`, which is now implemented with `before_commit` callbacks. What's next: * We shouldn't allow active transaction state when checking in or out from the connection pool. Verify that conns are clean. * Closer review of txn manager sad paths. Are we missing other spots where we'd end up with incorrect txn state? What's the worst that can happen if txn state drifts? How can we guarantee it doesn't and contain the fallout if it does? Thanks for @tomafro for expert diagnosis!

Without `:refrences` the normal output is generated: class CreateJoinTableShowroomUser < ActiveRecord::Migration[5.0] def change create_join_table :showrooms, :users do |t| # t.index [:showroom_id, :user_id] # t.index [:user_id, :showroom_id] end end end

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rails has abstract Reflection classes (`MacroReflection`, `AssociationReflection` etc.) and concrete Reflection classes (e.g. `HasManyReflection`, `HasOneReflection` etc.). In many case `calculate_constructable` returns `true`, so change `calculate_constructable` to always return `true` and override this method if necessary.
