We thus represent an optional schema member FOO as two C members: a FOO with the member's type, and a bool has_FOO. Likewise for function arguments. However, has_FOO is actually redundant for a pointer-valued FOO, which can be null only when has_FOO is false, i.e. has_FOO =3D=3D !!FOO. Except for arrays, where we a null FOO can also be a present empty array. The redundant has_FOO are a nuisance to work with. Improve the generator to elide them. Uses of has_FOO need to be replaced as follows. Tests of has_FOO become the equivalent comparison of FOO with null. For brevity, this is commonly done by implicit conversion to bool. Assignments to has_FOO get dropped. Likewise for arguments to has_FOO parameters. Beware: code may violate the invariant has_FOO =3D=3D !!FOO before the transformation, and get away with it. The above transformation can then break things. Two cases: * Absent: if code ignores FOO entirely when !has_FOO (except for freeing it if necessary), even non-null / uninitialized FOO works. Such code is known to exist. * Present: if code ignores FOO entirely when has_FOO, even null FOO works. Such code should not exist. In both cases, replacing tests of has_FOO by FOO reverts their sense. We have to fix the value of FOO then. To facilitate review of the necessary updates to handwritten code, add means to opt out of this change, and opt out for all QAPI schema modules where the change requires updates to handwritten code. The next few commits will remove these opt-outs in reviewable chunks, then drop the means to opt out. Signed-off-by: Markus Armbruster Reviewed-by: Daniel P.

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 tests/qapi-schema/qapi-schema-test.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here.

It leaves @has_node_name false, violating the "has_node_name =3D=3D !!node_name" invariant. Unclean. Falls apart when we elide @has_node_name (next commit): then QAPI frees the same value twice, once for @node_name and once @name. iotest 307 duly explodes. Goes back to commit c62d24e906 "blockdev-nbd: Boxed argument type for nbd-server-add" (v5.0.0). Got moved from qmp_nbd_server_add() to nbd_export_create() (commit 56ee86261e), then copied back (commit b6076afcab). Commit 8675cbd68b "nbd: Utilize QAPI_CLONE for type conversion" (v5.2.0) cleaned up the copy in qmp_nbd_server_add() noting Second, our assignment to arg->name is fishy: the generated QAPI code for qapi_free_NbdServerAddOptions does not visit arg->name if arg->has_name is false, but if it DID visit it, we would have introduced a double-free situation when arg is finally freed. Exactly. However, the copy in nbd_export_create() remained dirty. Clean it up. Since the value stored in member @name is not actually used outside this function, use a local variable instead of modifying the QAPI object.

charset="utf-8" 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/block*.json. Said commit explains the transformation in more detail. There is one instance of the invariant violation mentioned there: qcow2_signal_corruption() passes false, "" when node_name is an empty string. Take care to pass NULL then. The previous two commits cleaned up two more. Additionally, helper bdrv_latency_histogram_stats() loses its output parameters and returns a value instead.

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/char.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here.

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/migration.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here.

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/misc.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here.

charset="utf-8" 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/net.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here.
