Bug 74452 – IndexedDB: Can't pass DOMStringList to IDBDatabase.transaction()

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Joshua Bell]

Sample:

indexedDB = window.indexedDB || window.webkitIndexedDB;
indexedDB.open('db-test' + String(new Date)).onsuccess = function(e) {
  var db = e.target.result;
  db.setVersion('1').onsuccess = function(e) {
    var trans = e.target.result;
    trans.oncomplete = function() { test(db); };
  };
};

function test(db) {
  var dsl = db.objectStoreNames;
  var trans = db.transaction(dsl);
}

Expected: db.transaction() succeeds with ["store"] as the scope
Actual: INVALID_ACCESS_ERR is thrown

The code generator spits out:

  if ( ...  V8DOMStringList::HasInstance(args[0]) ... ) { ... }

And later:

  EXCEPTION_BLOCK(RefPtr<DOMStringList>, storeNames, v8ValueToWebCoreDOMStringList(MAYBE_MISSING_PARAMETER(args, 0, Mi
ssingIsUndefined)));

.. but v8ValueToWebCoreDOMStringList doesn't actually handle DOMStringList arguments. Dur.....

This worked prior to M17 because bogus first arguments to IDBDatabase.transaction() were treated as [] (empty-array) which meant "use all stores", but that functionality was removed.

Just removed a blank line. (DOS line endings in the layout test blinded me.)
