Subject: [PULL 04/13] tests/qapi-schema: Correct two 'if' conditionals
Date: Fri,  3 Sep 2021 21:32:00 +0200	[thread overview]
Message-ID: <20210903193209.1426791-5-armbru@redhat.com> (raw)
In-Reply-To: <20210903193209.1426791-1-armbru@redhat.com>

A definition's conditional should imply the conditionals of types it
uses.  If it doesn't, some configurations won't compile.

Example (from tests/qapi-schema/qapi-schema-test.json):

    { 'union': 'TestIfUnion', 'data':
      { 'foo': 'TestStruct',
	'bar': { 'type': 'str', 'if': 'TEST_IF_UNION_BAR'} },
      'if': { 'all': ['TEST_IF_UNION', 'TEST_IF_STRUCT'] } }

    { 'command': 'test-if-union-cmd',
      'data': { 'union-cmd-arg': 'TestIfUnion' },
      'if': 'TEST_IF_UNION' }

generates

    #if (defined(TEST_IF_UNION)) && (defined(TEST_IF_STRUCT))
    typedef struct TestIfUnion TestIfUnion;
    #endif /* (defined(TEST_IF_UNION)) && (defined(TEST_IF_STRUCT)) */

and

    #if defined(TEST_IF_UNION)
    void qmp_test_if_union_cmd(TestIfUnion *union_cmd_arg, Error **errp);
    void qmp_marshal_test_if_union_cmd(QDict *args, QObject **ret, Error **errp);
    #endif /* defined(TEST_IF_UNION) */

which doesn't compile when !defined(TEST_IF_STRUCT).

Messed up in f8c4fdd6ae "tests/qapi: Cover commands with 'if' and
union / alternate 'data'", v4.0.0.  Harmless, as we don't actually use
this configuration.  Correct it anyway, along with another instance.

This loses coverage for 'not'.  The next commit will bring it back.
