When safe mode is enabled, Magento creates a CSV file each time a destructive operation for a table or column occurs. The rollback operation changes the type from INT to CHAR. For example, changing the column type from CHAR to INT is a destructive operation. Opposite to destructive operations (ODO) - In the case of a failed Magento installation, SQL DDL operations that are the opposite of destructive operations can be used for rollback. The following operations are destructive: Several types of operations have an effect on data dumps and rollbacks.ĭestructive operations (DO) - SQL DDL operations that cause data deletion or data corruption.

Before you rollback, you must first check out code to the previous version of Magento. data-restore=1 - (Used with the setup:upgrade command only.) Performs a rollback.
#Ant migration tool destructive package upgrade#
safe-mode=1 - Creates a data dump during the installation or upgrade process. Magento provides options to the setup:install and setup:upgrade commands that enable safe installations and rollbacks:
#Ant migration tool destructive package manual#
These arguments are optional–you do not have to create a manual dump during a system upgrade. The dumped data can then be restored manually or automatically. To help prevent data loss, you can specify command line options that dump all the data that could be lost as a result of an installation.

For example, a developer can make a mistake and potentially remove a structural element from the database, causing data loss. The advantage and the main problem of declarative schema is that it can blindly modify the database schema.

You can use these SQL statements for debugging and optimizing performance processes. This file contains all the DDL SQL statements that are generated during installation. To enable dry run mode, run one of the following commands:Īs a result of specifying the -dry-run=1 flag, Magento writes a log file at /var/log/dry-run-installation.log. The schemas and data will be the same before and after installation. In dry run mode, the database state does not change. A useful way to ensure this is use dry run mode to examine all the DDL SQL statements that are generated during the declarative installation process. It is important that declarative installation/upgrade does not break anything. See Develop declarative data and schema patches for more information. When the InstallData.php script does not have any versions to compare, you can specify the first version of your module. The returned value of the getVersion method in this case should be equal to the value of a version in version_compare function in old scripts. This method allows you to skip changes that were applied in previous versions and were done by old scripts. The default is data.Īll released modules that previously used upgrade scripts must support backward compatibility by implementing \Magento\Framework\Setup\Patch\PatchVersionInterface and the getVersion method.
#Ant migration tool destructive package Patch#
type - Specifies what type of patch to generate. revertable - Determines whether the patch is revertable.

To convert your install or upgrade script, run one of the following commands:īin/magento setup:db-declaration:generate-patch The Schema Listener tool listens for schema changes and attempts to change Magento code, so it should not be run in production mode.

As Magento is installed or upgraded, the system logs all schema changes per module, then persists the changes in a series of db_schema.xml files (one per affected module). To use this tool, you specify an argument when you run the setup:install or setup:upgrade CLI command. The Schema Listener Tool converts pre-Magento 2.3 migration scripts into declarative schema. Convert install/upgrade schema scripts to db_schema.xml files Once you start with data patches, you cannot continue to use upgrade scripts. These commands also help you test your changes, roll back your changes if anything goes wrong, and help your module maintain backward compatibility. Magento provides several commands to help convert your installation and upgrade scripts to declarative schema.
