Breaking: #88741 - cHash calculation in indexed search removed
|
|
==============================================================
|
|
|
|
See :issue:`88741`
|
|
|
|
Description
|
|
===========
|
|
|
|
When indexing a page, the indexer of `Indexed search` previously kept the used cHash and the
|
|
used "cHashParams" for storing search entries. This is not necessary anymore, as Site Handling now
|
|
contains the relevant arguments already in the search entry as well. This can be removed now.
|
|
|
|
In addition, when setting up an Indexing configuration, the option to respect cHash is removed,
|
|
as this is done automatically when needed.
|
|
|
|
The public property :php:`TYPO3\CMS\IndexedSearch\Indexer->cHashParams` has been removed.
|
|
|
|
The sixth method argument of :php:`TYPO3\CMS\IndexedSearch\Indexer->backend_initIndexer()`
|
|
has been removed.
|
|
|
|
The following database fields are unused and have been removed:
|
|
|
|
* :sql:`index_config.chashcalc`
|
|
* :sql:`index_phash.cHashParams`
|
|
|
|
The database field :sql:`index_debug.debuginfo` now contains data stored in a JSON-formatted string
|
|
instead of a serialized PHP string.
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
Manual database queries accessing the database fields will result in SQL errors.
|
|
|
|
In addition, accessing the removed property or using the sixth argument of the changed public method
|
|
will have no effect anymore.
|
|
|
|
|
|
Affected Installations
|
|
======================
|
|
|
|
TYPO3 installations using Indexed Search and custom configuration or extending functionality
|
|
of Indexed Search.
|
|
|
|
|
|
Migration
|
|
=========
|
|
|
|
No migration needed, as everything works as before. The data is now stored in
|
|
the database field as JSON-encoded string `index_phash.static_page_arguments`.
|
|
|
|
In case of using debug information for Indexed Search (index with enabled debug information),
|
|
where data was previously stored in `index_debug.debuginfo` as serialized PHP string,
|
|
indexing needs to be rebuilt, but only to render the debug information properly in the TYPO3 Backend
|
|
module. If debug information is not enabled, re-indexing is not necessary.
