From adbe794a6ef7e8c52cec2dc3c8685f1a96507f24 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20P=2E=20Berrang=C3=A9?= Date: Fri, 12 Jul 2024 14:24:52 +0100 Subject: [PATCH] qga: conditionalize schema for commands requiring libudev MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rather than creating stubs for every command that just return QERR_UNSUPPORTED, use 'if' conditions in the schema to fully exclude generation of the filesystem trimming commands on POSIX platforms lacking required APIs. 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.
