Breaking: #92693 - Remove LinkHandler Linktype in Linkvalidator

See Issue #92693

Description

Linkvalidator ships with several link type classes that are used to check specific links such as ExternalLinktype, Filelinktype etc.

The link type LinkHandler is no longer used by default (see Page TSconfig mod.linkvalidator.linktypes). It was used to check links of the extension “linkhandler” which is now outdated. The latest version supports TYPO3 4.1.0.

LinkHandler functionality was integrated into the core in TYPO3 8, but the format of the links has changed since then.

The LinkHandler link type expects links which start with “record:” - a syntax that is now outdated.

Links to records are successfully checked in the InternalLinktype class.

Impact

It is no longer possible to use the “linkhandler” link type. Setting this in the configuration will not have any effect.

Affected Installations

There should be no affected installations as the linkhandler extension and the corresponding format of the links has long been outdated.

Migration

Normally, no migration is necessary.

You should remove the linkhandler link type from the page TSconfig configuration:

- mod.linkvalidator.linktypes = db,file,external,linkhandler
+ mod.linkvalidator.linktypes = db,file,external

You should no longer use ts:linkhandler.reportHiddenRecords = 0.

- mod.linkvalidator.linkhandler.reportHiddenRecords = 0
