Test IndexedDB's key generator behavior.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".


indexedDB = self.indexedDB || self.webkitIndexedDB || self.mozIndexedDB || self.msIndexedDB || self.OIndexedDB;


Verify that each object store has an independent key generator.
indexedDB = self.indexedDB || self.webkitIndexedDB || self.mozIndexedDB || self.msIndexedDB || self.OIndexedDB;

indexedDB.deleteDatabase(dbname)
indexedDB.open(dbname)
store1 = db.createObjectStore('store1', { autoIncrement: true })
store1.put('a')
request = store.get(1)
store2 = db.createObjectStore('store2', { autoIncrement: true })
store2.put('a')
request = store.get(1)
store1.put('b')
request = store.get(2)

request = store.get(2)
PASS Got "a" for key: 1
PASS Got "a" for key: 1
PASS Got "b" for key: 2
PASS Got "b" for key: 2
db.close()

Verify that the key generator is not updated if insertion fails
indexedDB = self.indexedDB || self.webkitIndexedDB || self.mozIndexedDB || self.msIndexedDB || self.OIndexedDB;

indexedDB.deleteDatabase(dbname)
indexedDB.open(dbname)
store = db.createObjectStore('store1', { autoIncrement: true })
index = store.createIndex('index1', 'ix', { unique: true })
store.put({ ix: 'a'})

store.put({ ix: 'b'})
request = store.get(2)
PASS Got {"ix":"a"} for key: 1
PASS Got {"ix":"b"} for key: 2

Verify that the key generator is not affected by item removal (delete or clear).
indexedDB = self.indexedDB || self.webkitIndexedDB || self.mozIndexedDB || self.msIndexedDB || self.OIndexedDB;

indexedDB.deleteDatabase(dbname)
indexedDB.open(dbname)

request = store.get(4)
PASS Got "a" for key: 1
PASS Got "b" for key: 2
PASS Got "c" for key: 3
PASS Got "d" for key: 4

Verify that the key generator is only set if and only if a numeric key greater than the last generated key is used.

db.close()

Verify that aborting a transaction resets the key generator state.
indexedDB = self.indexedDB || self.webkitIndexedDB || self.mozIndexedDB || self.msIndexedDB || self.OIndexedDB;

indexedDB.deleteDatabase(dbname)
indexedDB.open(dbname)

Ensure key generator state is maintained across connections:
