Examples: - adding or removing a column then doing a 'SELECT *' - removing the foo column then doing a 'SELECT bar.foo' In normal operation this isn't a problem, we can rescue the error, deallocate the prepared statement and re-issue the command. However in PostgreSQL transactions, once any command fails, the transaction becomes 'poisoned' and any subsequent commands will raise InFailedSQLTransaction. This includes DEALLOCATE statements, so the default deallocation strategy instead of removing the cached prepared statement instead raises InFailedSQLTransaction. Why this is bad =============== 1. InFailedSQLTransaction is a fairly cryptic error and doesn't communicate any useful information about what has actually gone wrong. 2. In the naive implementation the prepared statement never gets deallocated - it stays alive for the length of the session taking up memory on the postgres server. 3. It is unsafe to retry the transaction because the bad prepared statement is still in the cache and we would see the exact same failure repeated. Solution ======== If we are outside a transaction we can continue to handle these failures gracefully in the usual way. Inside a transaction instead of issuing a DEALLOCATE command that will certainly fail, we now raise ActiveRecord::PreparedStatementCacheExpired. This can be handled further up the stack, notably inside TransactionManager#within_new_transaction. Here we can make sure to first rollback the transaction, then safely issue DEALLOCATE statements to invalidate the rest of the cached prepared statements. This also allows the user (or some gem) the opportunity to catch this error and voluntarily retry the transaction if a schema change causes the prepared statement cache to become invalidated. Because the outdated statement has been deallocated, we can expect the transaction to succeed on the second try.
* | | Respect through association scopes when used with polymorphicSean Griffin2016-02-292-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the `source_type` option is passed to a has_many through, the resulting `Reflection` will be an instance of `PolymorphicReflection` and not `ThroughReflection`, meaning that it will ignore the scopes that it needs to apply from the through reflections. This adds an additional delegation call to remedy this. I've been finding the reflection code completely impenetrable lately, it could use some major love. Fixes #22726

* | | | Ensure suppressor runs before validationseileencodes2016-02-244-2/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I ran into an issue where validations on a suppressed record were causing validation errors to be thrown on a record that was never going to be saved. There isn't a reason to run the validations on a record that doesn't matter. This change moves the suppressor up the chain to be run on the `save` or `save!` in the validations rather than in persistence. The issue with running it when we hit persistence is that the validations are run first, then we hit persistance, and then we hit the suppressor. The suppressor comes first. The change to the test was required since I added the `validates_presence_of` validations. Adding this alone was enough to demonstrate the issue. I added a new test to demonstrate the new behavior is explict.

Based on the existing tests and behavior we wanted we determined the best way to do that was by checking if `!record.peristed? || record.changed? || record.marked_for_destruction?` This change didn't make it into a release until now. When #23790 was opened we realized that `valid?` and `invalid?` were broken and did not work on persisted records because of the `!record.persisted?`. While there is still a bug that #17621 brought up, this change was too drastic and should not be a RC blocker. I will work on fixing this so that we don't break `valid?` but also aren't validating parent records through child records if that parent record is validate false. This change removes the code changes to validate and the corresponding tests. It adds tests for two of the bugs found since Rails 5 beta2 release. Fixes #17621

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This resolves a bug where if the primary key used is not `id` (ex: `uuid`), and has a `validates_uniqueness_of` in the model, a uniqueness error would be raised. This is a partial revert of commit `119b9181ece399c67213543fb5227b82688b536f`, which introduced this behavior.
