From 238e9202a25bbac9dfc3cfc2c87a3c095cb2268c Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Fri, 4 Nov 2022 17:07:08 +0100 Subject: [PATCH] qapi transaction: Elide redundant has_FOO in generated C MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The has_FOO for pointer-valued FOO are redundant, except for arrays. They are also a nuisance to work with. Recent commit "qapi: Start to elide redundant has_FOO in generated C" provided the means to elide them step by step. This is the step for qapi/transaction.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here. In qmp_transaction(), we can't just drop parameter @has_props, since it's used to track whether @props needs to be freed. Replace it by a local variable.
