From 49d8c8e2374e0ed10e8d510760bd993e311cfb1a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Daniel=20P=2E=20Berrang=C3=A9?= Date: Fri, 12 Jul 2024 14:24:50 +0100 Subject: qga: conditionalize schema for commands requiring fsfreeze 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 freezing commands on POSIX platforms lacking the 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.
