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 Because the outdated statement has been deallocated, we can expect the transaction to succeed on the second try.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 Griffin2016-02-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* | | | | Fix uniqueness validation with an after_create hook.Joe Rafaniello2016-02-251-1/+1

* | | | | Ensure suppressor runs before validationseileencodes2016-02-241-1/+5

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

* | | | | | | | Always validate record if validating a virtual attributeeileencodes2016-02-203-3/+3

The change made in 27aa4dd updated validations to check if a record was `changed?` or `marked_for_destruction?` or not `persisted?`. It did not take into account virtual attributes that do not affect the model's dirty status. The only way to fix this is to always validate the record if the attribute does not belong to the set of attributes the record expects (in `record.attributes`) because virtual attributes will not be in that hash. I think we should consider deprecating this particular behavior in the future and requiring that the user mark the record dirty by noting that the virtual attribute will change. Unfortunately this isn't easy because we have no way of knowing that you did the "right thing" in your application by marking it dirty and will get the deprecation warning even if you are doing the correct thing. For now this restores expected behavior when using a virtual attribute by always validating the record, as well as adds tests for this case. I was going to add the `!record.attributes.include?(attribute)` to the `should_validate?` method but `uniqueness` cannot validate a virtual attribute with nothing to hold on to the attribute. Because of this `should_validate?` was about to become a very messy method so I decided to split them up so we can handle it specifically for each case.

This allows things like `MyThing.all.in_groups_of(3) { ... }` to continue working as they did before commit 9d79334.
