TYPO3 Core

The issue is that with mod.linkvalidator.linkhandler.reportHiddenRecords = 0, the Linkvalidator will still (manually) check links on hidden pages, and the editor can see there are bad links in the numbers shown in the badge. But they won't be listed in the report until the page is unhidden.

I cannot reproduce this in TYPO3 version 10. As said, the option reportHiddenRecords is only used in the LinkHandler linktype which is not used by default. Effectively, this determines which linktypes are used:

1. TSconfig

1. this is the default
   mod.linkvalidator.linktypes = db,file,external

2. Configuration in ext_localconf.php

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['linkvalidator']['checkLinks']['db'] = \TYPO3\CMS\Linkvalidator\Linktype\InternalLinktype::class;
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['linkvalidator']['checkLinks']['file'] = \TYPO3\CMS\Linkvalidator\Linktype\FileLinktype::class;
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['linkvalidator']['checkLinks']['external'] = \TYPO3\CMS\Linkvalidator\Linktype\ExternalLinktype::class;
$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['linkvalidator']['checkLinks']['linkhandler'] = \TYPO3\CMS\Linkvalidator\Linktype\LinkHandler::class;

As you can see, the LinkHandler link type is configured in ext_localconf.php but not used in TSconfig (by default). In the InternalLinktype the option reportHiddenRecords is not used.

Can you please add your configuration and describe a reproducible test case? Check if changing the mod.linkvalidator.linktypes to the default helps.

I'm sorry about the lack of detail in my report.

Steps to reproduce (v10.4.14, core only, default Page TSconfig):

1. Create a hidden page, with a visible CE, with a bad internal link or link to a hidden page.
2. Run the link checker manually for that page. The bad link will be found even though mod.linkvalidator.checkhidden = 0 by default. (bug)
3. Switch to the report. You can see there is a bad link (badge says 1), but below, it says that there are no broken links to show. (bug)
4. Unhide the page. Now the bad link(s) will be listed.
5. Hide the page again. Now the numbers will all be zero with no listed links. This is the expected behavior with the default Page TSconfig (mod.linkvalidator.checkhidden = 0).

The # of bad links listed should equal the number of links listed for the selected types.

Perhaps it is something to do with the way the linkvalidator cache is used. The checkhidden condition is checked differently for the badges vs. the actual list.
