From 4be55a4fce18de5ce660a0c2b0961a6333fd957f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Daniel=20P=2E=20Berrang=C3=A9?= Date: Fri, 12 Jul 2024 14:24:54 +0100 Subject: [PATCH] qga: conditionalize schema for commands not supported on other UNIX MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Rather than creating stubs for every command that just return QERR_UNSUPPORTED, use 'if' conditions in the QAPI schema to fully exclude generation of the commands on other UNIX. The command will be rejected at QMP dispatch time instead, avoiding reimplementing rejection by blocking the stub commands. This changes the error message for affected commands from {"class": "CommandNotFound", "desc": "Command FOO has been disabled"} to {"class": "CommandNotFound", "desc": "The command FOO has not been found"} This has the additional benefit that the QGA protocol reference now documents what conditions enable use of the command.
