           Summary: IndexedDB: IDBObjectStore methods should throw
                    TypeError if required arguments are missing
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal

         Component: New Bugs

http://dvcs.w3.org/hg/IndexedDB/raw-file/tip/Overview.html#idl-def-IDBObjectStore lists required arguments to put(), add(), delete(), get(), createIndex(), index(), and deleteIndex(). As per the WebIDL spec, calling functions with missing required arguments should throw a TypeError. This test calls these functions with no arguments, or with too few arguments, to see what happens.

Expected behavior: throw TypeError
Actual behavior: no exception thrown

Patch included. The fix is to remove the LegacyDefaultOptionalArguments flag from IDBObjectStore.idl, which will force the code generator to check for required arguments and throw TypeError when they are missing.
