PageImages Maintenance Script finds not all Images
Closed, ResolvedPublic5 Estimated Story Points


After running 'php extensions/PageImages/maintenance/initImageData.php' manually, no images where found in ?action=info on each article.

Someone postet a workaround here:

This could be integrated into Mediawiki with this change:

I suspect, something within includes/deferred/LinksUpdate.php is the real reason.

Developer notes

When running from a maintenance script LinksUpdate does not provide the Revision id (presumably as LinksUpdate::setRevision is never called). When this is the case, we can make use of the Title to obtain the relevant information.

Event Timeline

I had the same issue with the following, PageImages isn't able to select and store images and when the PageImage maintenance script initImageData.php is run, the following errors are returned:

PHP Warning:  array_flip(): Can only flip STRING and INTEGER values! in /htdocs/extensions/PageImages/includes/ParserFileProcessingHookHandlers.php on line 123
PHP Warning:  array_flip(): Can only flip STRING and INTEGER values! in /htdocs/extensions/PageImages/includes/ParserFileProcessingHookHandlers.php on line 123

I followed the recommendation posted here:

It recommended updating LinksUpdateHookHandler.php (in PageImages/includes/) with the following:
Replace: $rev = $linksUpdate->getRevision();
With: $rev = Revision::newFromTitle($linksUpdate->getTitle());

This works and my images appear, however after running the PageImage maintenance script initImageData.php, the following error are returned:

PHP Notice:  Undefined variable: offsetStr in /htdocs/extensions/Cargo/includes/parserfunctions/CargoCompoundQuery.php on line 87
