Can not find new domain with qubesadmin - Qubes

[donob4n]

Qubes OS version:

R4

Affected component(s):

Potentially all things using import Qubes from qubesadmin

---

Steps to reproduce the behavior:

Currently I am trying to implement dbus events in Qube Manager. When recieve a 'DomainAdded' signal a callback function is called for handling it. Since it only knows the 'qid' of the domain it loops through qubes_app.domains and gets it. Unfortunately sometimes (maybe when there are some amount of domains) it does not find it. Here is a example log after creating two new domains:

/org/qubes/DomainManager1/domains/36

NOT FOUND

Expected behavior:

If we recieved a 'DomainAdded' signal, that domain should be in Qubes.domains.

Actual behavior:

It is not.

General notes:

Maybe is this due some kind of caching? After restarting qube-manager the new domain appears fine.

Making new Qubes() objects when I need to find a new domain also works fine.

Yes, caching, see qubes_app.domains.clear_cache().

Ey @marmarek

Could this cache be handled internally? I mean it gets cleared automatically when needed, otherwise I see a lot of places where it needs to be cleaned and also its pretty error prune.
