Subject: [PATCH] virjsontest: Add test for nesting depth
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add an example of 250 layer deep nested JSON to make sure the parser
supports it. This is in order to maintain compatibility with external
snapshots in qemu, where such a deeply nested document is returned with
a 'query-block' QMP call.
I've used a fake JSON as a real reply from qemu is around 1.4MiB for a
200 deep image chain.
