Breaking: #92457 - Extension Repository database table removed

See Issue #92457

Description

The existing extension manager had functionality to add multiple repositories by adding new database rows into the database table tx_extensionmanager_domain_model_repository.

Because this functionality has been superseded by a configurable and more robust Remote API, where the configuration of possible additional TER endpoints are not stored in the database anymore, the database table is removed.

Impact

Accessing tx_extensionmanager_domain_model_repository will result in a SQL error, as existing TYPO3 installations will drop this database table in the Database Compare View during upgrade.

Affected Installations

TYPO3 installations with third-party extensions accessing this database table, which is highly unlikely.

Also, TYPO3 installations depending on additional repositories rather than the official TYPO3 Extension Repository (TER) at extensions.typo3.org, will not work anymore.

Migration

Additional Extension Repositories (remotes) have to be added in Configuration/Services.yaml using the extension.remote tag.

extension.remote.myremote:
  class: 'TYPO3\CMS\Extensionmanager\Remote\TerExtensionRemote'
  arguments:
    $identifier: 'myremote'
    $options:
       remoteBase: 'https://my_own_remote/'
  tags:
    - name: 'extension.remote'
      enabled: true
