From a65b3de100a1cf8bac39d9255610c11803e43130 Mon Sep 17 00:00:00 2001 From: Sergei Morozov Date: Thu, 2 Jan 2020 22:50:30 -0800 Subject: [PATCH] Removed the OCI8Connection::getExecuteMode() method The existing relationship between the connection and its statement violate the ISP principle. Instead of having access only to the execution mode of the connection, statements have access to the entire connection API. Having a method which is not defined in the driver connection interface makes it impossible to mark the method `final` (#3590). --- .../DBAL/Driver/OCI8/ExecutionMode.php | 29 ++++++++++++++++ .../DBAL/Driver/OCI8/OCI8Connection.php | 25 +++++--------- .../DBAL/Driver/OCI8/OCI8Statement.php | 24 +++++++++----- .../DBAL/Driver/OCI8/ExecutionModeTest.php | 33 +++++++++++++++++++ 4 files changed, 86 insertions(+), 25 deletions(-) create mode 100644 lib/Doctrine/DBAL/Driver/OCI8/ExecutionMode.php create mode 100644 tests/Doctrine/Tests/DBAL/Driver/OCI8/ExecutionModeTest.php diff --git a/lib/Doctrine/DBAL/Driver/OCI8/ExecutionMode.php b/lib/Doctrine/DBAL/Driver/OCI8/ExecutionMode.php new file mode 100644 index 00000000000..aa16cdd35d4 --- /dev/null +++ b/lib/Doctrine/DBAL/Driver/OCI8/ExecutionMode.php @@ -0,0 +1,29 @@ +isAutoCommitEnabled = true;
