It really depends on exactly what the problem scenario is. Currently,
whenever *any* QML file changes, the whole cache is dropped and rebuilt.
This includes SDK and base QML deps, not only files shipped by the app
itself.

The only case where it is currently not rebuilt is when a provider
library changes its QML bindings ABI. For this we are looking into ways
to encode library versions on the magic headers of the cache file,
although for now considering libraries are only updated on image
upgrade, the cache should ensure validity. The only breaking case is
when the developer pushes a new QML plugin with different ABI than what
the cache was built against.

So I guess the question is:

What was the scenario/issue that happened which lead to this bug?

Title:
  QML cache gets stale too easily

Status in qtdeclarative-opensource-src package in Ubuntu:
  Confirmed

Bug description:
  It's happened many times now that after looking for an issue the
  source of it ended up to be stale QML cache.

  We need the cache to be cleared more aggressively, likely on any QML-
  related package installation. App-specific cache should be (if it's
  not) cleared on install (or maybe better - removal) and upgrade.
