| Verify edge cases that lazy index population in an IndexedDB implementation might reveal. |
| |
| 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; |

| indexedDB.deleteDatabase(dbname) |
| indexedDB.open(dbname) |
| Deleted all object stores. |
| store = connection.createObjectStore('store') |
| store.createIndex('index1', 'name', {unique: true}) |
| Verify that uniqueness constraints are enforced with a pre-existing index: |
| trans = connection.transaction('store', 'readwrite') |
| store = trans.objectStore('store') |
| request1 = store.put({name: 'bob'}, 1) |
| request2 = store.put({name: 'bob'}, 2) |
| state = 0 |
| request1 received success event |
| PASS ++state is 1 |
| request2 received error event |
| PASS ++state is 2 |
| transaction aborted |
| PASS ++state is 3 |
| PASS trans.error.name is 'ConstraintError' |
| |
| Verify that uniqueness constraints are enforced when index is created before puts: |
| connection.close() |
| indexedDB.open(dbname, 2) |
| deleteAllObjectStores(connection) |
| Deleted all object stores. |
| store = connection.createObjectStore('store') |
| store.createIndex('index2', 'name', {unique: true}) |
| request1 = store.put({name: 'carol'}, 1) |
| request2 = store.put({name: 'carol'}, 2) |
| state = 0 |
| request1 (index2) received success event |
| PASS ++state is 1 |
| request2 (index2) received error event |
| PASS ++state is 2 |
| transaction aborted |
| PASS ++state is 3 |
| PASS trans.error.name is 'ConstraintError' |
| |
| Verify that uniqueness constraints are enforced when index is created after puts: |
| indexedDB.open(dbname, 3) |
| deleteAllObjectStores(connection) |
| Deleted all object stores. |
| store = connection.createObjectStore('store') |
| request1 = store.put({name: 'ted'}, 1) |
| request2 = store.put({name: 'ted'}, 2) |
| store.createIndex('index3', 'name', {unique: true}) |
| state = 0 |

| request2 received success event |
| PASS ++state is 2 |

| PASS ++state is 3 |
| PASS trans.error.name is 'ConstraintError' |
| |
| Verify that uniqueness constraints are enforced when index is created between puts: |
| indexedDB.open(dbname, 4) |
| deleteAllObjectStores(connection) |
| Deleted all object stores. |
| store = connection.createObjectStore('store') |
| request1 = store.put({name: 'alice'}, 1) |
| store.createIndex('index4', 'name', {unique: true}) |
