Bug 86123 – IndexedDB: Implement spec behavior for multiEntry indexes with invalid/duplicate subkeys

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Joshua Bell]

The spec details the handling of multiEntry key paths where the key path yields an array and the array includes values that are duplicates or invalid sub-keys. WebKit's implementation (WebCore/binding/v8/IDBBindingUtilities.cpp) yields an overall InvalidType key if any of the subkeys are invalid.

http://dvcs.w3.org/hg/IndexedDB/raw-file/tip/Overview.html#dfn-steps-for-storing-a-record-into-an-object-store

7.4 If index's multiEntry flag is true, and index key is an Array, remove any elements from index key that are not valid keys and remove any duplicate elements from index key such that only one instance of the duplicate value remains.

For example, the following value of index key [10, 20, null, 30, 20] is converted to [10, 20, 30].

Redundant with fall through.

> +                if (!m_index->addingKeyAllowed(indexKey->array()[i].get()))

Ouch, good catch.

Either put this callback all on one line, or correct the indentation.
