| Test IndexedDB IDBDatabase internal closePending flag |

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

| First, verify that the database connection is not closed: |
| PASS transaction = connection.transaction('store') did not throw exception. |
| |
| |
| Database closing steps |
| "1. Set the internal closePending flag of connection to true." |
| connection.close() |
| Expecting exception from connection.transaction('store') |
| PASS Exception was thrown. |
| PASS code is DOMException.INVALID_STATE_ERR |
| PASS ename is 'InvalidStateError' |
| Exception message: Failed to execute 'transaction' on 'IDBDatabase': The database connection is closing. |
| "2. Wait for all transactions created using connection to complete. Once they are complete, connection is closed." |
| transaction.oncomplete = testIDBDatabaseName |
| |
| |
| IDBDatabase.name: |
| "The function must return this name even if the closePending flag is set on the connection." |
| PASS connection.name is dbname |
| |
| |
| IDBDatabase.objectStoreNames: |
| "Once the closePending flag is set on the connection, this function must return a snapshot of the list of names of the object stores taken at the time when the close method was called." |
| request = indexedDB.open(dbname, 2) |

| PASS version_change_connection.objectStoreNames.contains('new_store') is true |
| PASS connection.objectStoreNames.contains('new_store') is false |
| version_change_connection.close() |
| |
| |
| IDBDatabase.transaction(): |
| "...if this method is called on a IDBDatabase instance where the closePending flag is set, a InvalidStateError exception must be thrown." |
| Expecting exception from connection.transaction('store') |
| PASS Exception was thrown. |
| PASS code is DOMException.INVALID_STATE_ERR |
| PASS ename is 'InvalidStateError' |
| Exception message: Failed to execute 'transaction' on 'IDBDatabase': The database connection is closing. |

| |
| "versionchange" transaction steps: |
| "Fire a versionchange event at each object in openDatabases that is open. The event must not be fired on objects which has the closePending flag set." |
| request = indexedDB.open(dbname) |
| connection = request.result |
| versionChangeWasFired = false |
| connection.onversionchange = function () { versionChangeWasFired = true; } |
| transaction = connection.transaction('store') |
| connection.close() |
| closePending is set, but active transaction will keep connection from closing |
| request = indexedDB.open(dbname, 3) |
| 'blocked' event fired, letting transaction complete and connection close |
| version_change_connection = request.result |
| PASS versionChangeWasFired is false |
| version_change_connection.close() |
| |
| |
| Database deletion steps: |
| "Fire a versionchange event at each object in openDatabases that is open. The event must not be fired on objects which has the closePending flag set." |
| request = indexedDB.open(dbname) |
| connection = request.result |
| versionChangeWasFired = false |

| transaction = connection.transaction('store') |
| connection.close() |
| closePending is set, but active transaction will keep connection from closing |
| request = indexedDB.deleteDatabase(dbname) |
| 'blocked' event fired, letting transaction complete and connection close |
| PASS versionChangeWasFired is false |
| PASS successfullyParsed is true |
