The maintenance script to update the content model doesn't finish.
FixProofreadIndexPagesContentModel::doDBUpdates
do {
$dbw->query(
'UPDATE page SET page_content_model = ' . $dbw->addQuotes( CONTENT_MODEL_PROOFREAD_INDEX ) .
' WHERE page_namespace = ' . intval( ProofreadPage::getIndexNamespaceId() ) .
' AND page_content_model = ' . $dbw->addQuotes( CONTENT_MODEL_WIKITEXT ) .
' ORDER BY page_namespace, page_title LIMIT ' . intval( $this->mBatchSize )
);
wfWaitForSlaves();
} while ( $dbw->affectedRows() > 0 );When run on vec.wikisource, the effect on the page table is as expected, all the rows was updated to 'proofread-index' (the CONTENT_MODEL_PROOFREAD_INDEX value)
BUT
the loop runs indefinitely, as $dbw->affectedRows() always return a greater than 0 value.
@Tpt asserts it works in dev environment and stops when done.
