Test that a database is recreated correctly when an open-with-version call is queued behind both a deleteDatabase and an open-with-version call

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

dbname = "intversion-long-queue.html"
indexedDB.deleteDatabase(dbname)
indexedDB.open(dbname)


prepareDatabase():
db = event.target.result


connection1Success():
connection1 = event.target.result
PASS db is connection1
connection1.onversionchange = connection1VersionChangeCallback
request = indexedDB.open(dbname, 2)
request.onsuccess = connection2Success
request.onupgradeneeded = connection2UpgradeNeeded
request.onblocked = connection2Blocked


connection1VersionChangeCallback():
PASS event.type is "versionchange"
PASS event.oldVersion is 1
PASS event.newVersion is 2


connection2Blocked():

request.onsuccess = deleteDatabaseSuccessCallback
request = indexedDB.open(dbname, 3)

request.onsuccess = connection3Success
connection1.close()


connection2UpgradeNeeded():
PASS event.oldVersion is 1

connection2Success():

PASS event.oldVersion is 0


connection3Success():
