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)
store2.put('b')
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'})
request = store.get(1)
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
db.close()

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(1)
store.delete(1)
store.put('b')
request = store.get(2)
store.clear()
store.put('c')
request = store.get(3)
store.delete(IDBKeyRange.lowerBound(0))
store.put('d')
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
db.close()

Verify that the key generator is only set if and only if a numeric key greater than the last generated key is used.
indexedDB = self.indexedDB || self.webkitIndexedDB || self.mozIndexedDB || self.msIndexedDB || self.OIndexedDB;

indexedDB.deleteDatabase(dbname)

PASS Got "h" for key: "foo"
PASS Got "i" for key: 10

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)
trans1 = db.transaction(['store'], 'readwrite')

store_t1.put('a')

Verify that keys above 2^53 result in errors.

Error event fired auto-incrementing past 2^53 (as expected)
PASS event.target.error.name is 'ConstraintError'
event.preventDefault()
PASS Got "d" for key: 2

Verify that keys above 2^64 result in errors.
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:
indexedDB = self.indexedDB || self.webkitIndexedDB || self.mozIndexedDB || self.msIndexedDB || self.OIndexedDB;

indexedDB.deleteDatabase(dbname)
indexedDB.open(dbname)
db.createObjectStore('store', {autoIncrement: true})

PASS successfullyParsed is true
