Comment 8 for bug 1521607

This is an historical note.

Glance has never supported JSON patch. It supports a "useful and compatible subset of the functionality" of JSON patch [0].

Additionally, it does not support full JSON pointers.

The problem may be that at some point the API reference doc was rewritten with reference to JSON patch and JSON pointers, not with reference to what Glance actually supports.

That being said, it would be better if Glance fully supported RFC6092, using a standard library (as Glare is doing). But I think that would require a spec.
