Feature: #77643 - Reimplement SqlSchemaMigrationService using Doctrine SchemaManager
|
|
====================================================================================
|
|
|
|
See :issue:`77643`
|
|
|
|
Description
|
|
===========
|
|
|
|
The SqlSchemaMigrationService has been reimplemented using a LL(*) Parser for CREATE TABLE
|
|
statements. The new parser supports MySQL syntax for CREATE TABLE statements. Based on the
|
|
abstract syntax tree produced by this parser Doctrine Table objects are created that
|
|
implement a DBMS independent representation of the schema and are used with the Doctrine
|
|
SchemaManager to handle the schema migrations needs of the TYPO3 core.
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
Update suggestions from the new SchemaMigrator are per connection, on all additional
|
|
connections only explicitly mapped tables are managed. MySQL specific data types are being
|
|
mapped to the closest matching standard type, for example TINYINT to SMALLINT. The support
|
|
for foreign keys has been enhanced as a result of the additional capabilities of the
|
|
Doctrine SchemaManager.
