  1. 8 core/modules/system/src/Tests/Database/TransactionTest.php \Drupal\system\Tests\Database\TransactionTest

Tests the transaction abstraction system.

We test nesting by having two transaction layers, an outer and inner. The outer layer encapsulates the inner layer. Our transaction nesting abstraction should allow the outer layer function to call any function it wants, especially the inner layer that starts its own transaction, and be confident that, when the function it calls returns, its own transaction is still "alive."

Call structure: transactionOuterLayer() Start transaction transactionInnerLayer() Start transaction (does nothing in database) [Maybe decide to roll back] Do more stuff Should still be in transaction A

  /**
   * Encapsulates a transaction's "inner layer" with an "outer layer".
   *
   * This "outer layer" transaction starts and then encapsulates the "inner
   * layer" transaction. This nesting is used to evaluate whether the database
   * transaction API properly supports nesting. By "properly supports," we mean
   * the outer transaction continues to exist regardless of what functions are
   * called and whether those functions start their own transactions.
   *
   * In contrast, a typical database would commit the outer transaction, start
   * a new transaction for the inner layer, commit the inner layer transaction,
   * and then be confused when the outer layer transaction tries to commit its
   * transaction (which was already committed when the inner transaction
   * started).
   *
   * @param $suffix
   *   Suffix to add to field values to differentiate tests.
   * @param $rollback
   *   Whether or not to try rolling back the transaction when we're done.
   * @param $ddl_statement
   *   Whether to execute a DDL statement during the inner transaction.
