Upgrading openHAB: best practise to monitor previously installed Marketplace add-ons

[binderth (Thomas Binder)]

Thanks a lot!

@rlkoshak

First, I think the way marketplace add-ons are handled during upgrades right now is broken. So please file an issue. It really should not just silently remove the add-ons.

from what I read here i assumed, it was done deliberately:

openHAB 4.2 Release Discussion

So, either things would definitely break because the binding isn’t loaded, or things may break if the binding is incompatible.

@rlkoshak

If you pull http://myohaddress:8080/rest/addons?serviceId=marketplace the following code shold give you the names of the add-ons that are installed compared to a list of add-ons you expect to be installed. (Note this is not tested, there will almost certainly be bugs. I’m assuming an auth token to access the API.)

this works just fine! Thanks!

(just a few simple changes:)

var expected = [ "Ephemeris Binding", "The Doctor Binding helps find issues with your system"];
var url = 'http://myohaddress:8080/rest/addons?serviceId=marketplace';
var headers = { "accept": "application/json",
                "Authorization": "Bearer oh.APIToken.UjC...",
                "WWW-Authenticate": "Basic"};
var allAddons = JSON.parse(actions.HTTP.sendHttpGetRequest(url, headers, 2000)); // probably should do some error checking here
var installed = allAddons.filter(addon => addon.installed == true).map(addon => addon.label); // array of the labels of the installed marketplace addons
var missing = expected.filter(addon => !installed.includes(addon));
var unexpected = installed.filter(addon => !expected.includes(addon));
var message = "";
if(missing.length > 0) {
 message = "The following expected marketplace add-ons are not installed: " + missing.join(', ');
}
if(unexpected.length > 0) {
  if(message !== "") message += '\n';
  message +="The following unexpected add-ons from the marketplace are installed: " + unexpected.join(', ');
}
if(message != "") {
  // generate alert
}
console.info("INFO check: ", message);
