Deprecation: #78222 - Late generation of autoload information is deprecated

See Issue #78222

Description

If TYPO3 is in non-composer mode, it used to automatically dump extension class loading information late during the bootstrap. This behavior is now deprecated.

Impact

TYPO3 installations in non-composer mode, now trigger a deprecation log entry in case extension autoload information is missing late in the bootstrap.

Affected Installations

TYPO3 installations in non-composer mode with deleted extension autoload information.

Migration

Class loading information can be re-dumped by

  • Activating or deactivating an extension
  • Running the dump command from the command line
  • In install tool (important actions)

The autoload files should never be deleted, but always only be re-dumped.
