iOS 8 bug + workaround

[pbruining]

Hello,

The iOS 8 implementation has a bug in it. When the database is opened for the first time iOS 8 returns an absurd high version number, 9223372036854776000. This prevents the upgrade mechanism from creating the object stores and indexes. I fixed it in the generated JavaScript for our project. Could you include my fix in the CoffeeScript?

Regards, Pieter

dbReq.onupgradeneeded = function(event) {
  // Change door GINO, iOS 8 geeft initeel een enorm getal als versie in plaats van 0:
  var oldVersion = event.oldVersion;
  if (oldVersion == 9223372036854776000) {
    oldVersion = 0;
  }
  var tx;
  db = event.target.result;
  tx = event.target.transaction;
  $log.log("$indexedDB: Upgrading database '" + db.name + "' from version " + oldVersion + " to version " + event.newVersion + " ...");
  applyNeededUpgrades(oldVersion, event, db, tx, $log);
};
