| * Correctly deallocate prepared statements if we fail inside a transactionSam Davies2015-11-051-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Addresses issue #12330 Overview ======== Cached postgres prepared statements become invalidated if the schema changes in a way that it affects the returned result. 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 Because the outdated statement has been deallocated, we can expect the transaction to succeed on the second try.

* | | Let t.foreign_key use the same `to_table` twiceGeorge Millo2016-02-151-2/+2
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously if you used `t.foreign_key` twice within the same `create_table` block using the same `to_table`, all statements except the final one would fail silently. For example, the following code: def change create_table :flights do |t| t.integer :from_id, index: true, null: false t.integer :to_id, index: true, null: false t.foreign_key :airports, column: :from_id t.foreign_key :airports, column: :to_id end end Would only create one foreign key, on the column `from_id`. This commit allows multiple foreign keys to the same table to be created within one `create_table` block.
* | Ensure prepared statement caching still occurs with Adequate RecordSean Griffin2016-02-112-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | In Rails 5, we're much more restrictive about when we do or don't cache a prepared statement. In particular, we never cache when we are sending an IN statement or a SQL string literal However, in the case of Adequate Record, we are *always* sending a raw SQL string, and we *always* want to cache the result.

* | Fix corrupt transaction state caused by `before_commit` exceptionsJeremy Daer2016-02-011-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a `before_commit` callback raises, the database is rolled back but AR's record of the current transaction is not, leaving the connection in a perpetually broken state that affects all future users of the connection: subsequent requests, jobs, etc. They'll think a transaction is active when none is, so they won't BEGIN on their own. 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!

| | | | | | | | | | | | | | | | | | | | | This PR introduces a key/value type store to Active Record that can be used for storing internal values. It is an alternative implementation to #21237 cc @sgrif @matthewd. It is possible to run your tests against your production database by accident right now. While infrequently, but as an anecdotal data point, Heroku receives a non-trivial number of requests for a database restore due to this happening. In these cases the loss can be large. To prevent against running tests against production we can store the "environment" version that was used when migrating the database in a new internal table. Before executing tests we can see if the database is a listed in `protected_environments` and abort. There is a manual escape valve to force this check from happening with environment variable `DISABLE_DATABASE_ENVIRONMENT_CHECK=1`.
