Ok, I think there is something seriously wrong with SMWSQLStore3Writers.
getCurrentPropertyTableContents only fetches one row and returns it as an
array. It should probably return several rows as an array of arrays.
Something like this:
$result = array();
$resultWrapper = $dbr->select( $propertyTable->getName(), '*',
array( 's_id' => $sid ), __METHOD__ );
while($row=$dbr->fetchRow($resultWrapper)) {
foreach($row as $key=>$value ){ //need to remove numeric keys;
bug or feature in MW's DatabaseMysql::fetchRow?
if ( is_int( $key ) ) {
unset($row[$key]);
}
}
$result[] = $row;
}
return $result;
Even then (with the array structures properly aligned) the array_diff_assoc
in preparePropertyTableUpdates is not going to work, because it does not
work recursively. Instead it just uses string representations of the
top-level elements. Which are all "Array" or some such for an array of
arrays. I don't know, how to fix it short of handcrafting some kind of
recursive diff.
