From 91fa93e516d080d440ead2ad4f88960545bd5b2c Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Thu, 18 Mar 2021 16:55:11 +0100 Subject: qapi: Implement deprecated-output=hide for QMP command results This policy suppresses deprecated bits in output, and thus permits "testing the future". Implement it for QMP command results. Example: when QEMU is run with -compat deprecated-output=hide, then {"execute": "query-cpus-fast"} yields {"return": [{"thread-id": 9805, "props": {"core-id": 0, "thread-id": 0, "socket-id": 0}, "qom-path": "/machine/unattached/device[0]", "cpu-index": 0, "target": "x86_64"}]} instead of {"return": [{"arch": "x86", "thread-id": 22436, "props": {"core-id": 0, "thread-id": 0, "socket-id": 0}, "qom-path": "/machine/unattached/device[0]", "cpu-index": 0, "target": "x86_64"}]} Note the suppression of deprecated member "arch".
