Hi,

I have two comments. The first one is about JSON export of an Installation. You declare it is like this when it comes to categories:

"categories" : ["football", "sport"]

However, with the current UPS of version 1.0.2, when you register some installation, it returns you this https://issues.jboss.org/browse/AGPUSH-1093

This issue should be addressed and since exporting of installations more or less means to marshall them into JSON, you hit this issue for sure so model should be updated to return only array of category names instead of its JSON representation.

The second comment is about security. I am begging you here from QA team to make it doable via REST and not (only) via UPS console because it simplifies tons of hacking around the code. Right now we are doing whole import by adding custom JAX-RS endpoints on top of UPS, we generate applications, variants and installations randomly as JSONs and send them to UPS to these batch endpoints and we are calling services to persist them.

You can find it here (1)

In case this would be done via REST, it would be no-brainer and huge time saver for QA guys.

Hi,
I would like to start a discussion around the import/export of installations in UPS. To track all the tasks, we have a ticket[1] also containing some sub-tasks.
Scope
For now we stick to installations, meanning we can import or export installations from a particular Variant. Import/Export for Variants will maybe come later but due to some security issues (mainly for iOS cert/passphrase) it's on hold.
Import Service
That's an easy one ;) since the service already exist [2]. It's a REST service and it uses the VariantId/Secret combination to authenticate.
Data format looks like :
[
   {
     "deviceToken" : "someTokenString",
     "deviceType" : "iPad",
     "operatingSystem" : "iOS",
     "osVersion" : "6.1.2",
     "alias" : "someUsername or email adress...",
     "categories" : ["football", "sport"]
   },
   {
     "deviceToken" : "someOtherTokenString",
     ...
   },
   ...
 ]
Export Service
Like import, it will use the variantId/secret combo to authenticate and retrieve the right variant to export the installations. The data structure format would of course looks like the one used for import.
Output format
How should provide the exported data ? I need your input here 1. Raw Json ? 2. Json file ? 3. Zip / tarball ?
UI
UI should be a nice to have
I would suggest to add 2 items (import and export) in the contextual menu that you can see in this screenshot :
For import, the user will have a file input and feedback on how many installations were imported. For export, the user just have to press an export button
Migration issues
So, that is a very important point that I would like to discuss. Even if we are able to import installations, the variantID_ and the __variantSecret will not match with those that are in the Clients.
Imagine the following scenario : I export 15000 installations, my datacenter burns, I create a new UPS instance, with a new Push App and a new Variant (so new VariantID and VariantSecret), then I inport the installations. Well, my 15000 clients will point to the wrong variant. For sure, they can be updated but that might not always be an option.
That is why I would like suggest the following change : Make VariantId and VariantSecret editable, so after someone has done an import he can change the values of the variants so it matches the clients.
I know we had this discussion before, but in the future we might want to change the naming around VariantId and VariantSecret, to me it sounds more like variantAPIKey / variantAPISecret
wdyt ?
Security
As said before, import/export uses variantId/variantSecret to authenticate. So if someone has access to these keys he could make a malicious import of 500k installations. What should we do for that ? We could give this access only to authenticated "console" users but then it would be hard to expose import/export as rest service (because of KC implication)
Please comment, ask questions , be crazy ...
