Recent testsuite additions show that fixing the obvious bug with bogus fields will also fix the case of an incomplete list visit; update the tests to match the new behavior. Simple testcase: ./x86_64-softmmu/qemu-system-x86_64 -nodefaults -nographic -qmp stdio -numa= node,size=3D1g failed to diagnose that 'size' is not a valid argument to -numa, and now once again reports: qemu-system-x86_64: -numa node,size=3D1g: Invalid parameter 'size' CC: qemu-stable@nongnu.org Signed-off-by: Eric Blake Reviewed-by: Michael Roth Tested-by: Laurent Vivier --- v2: trivial rebase to comment tweak in patch 1 --- qapi/opts-visitor.c | 6 +++--- tests/test-opts-visitor.c | 15 +++++++++------ 2 files changed, 12 insertions(+), 9 deletions(-) diff --git a/qapi/opts-visitor.c b/qapi/opts-visitor.c index 026d25b..b54da81 100644 --- a/qapi/opts-visitor.c +++ b/qapi/opts-visitor.c @@ -164,7 +164,7 @@ opts_check_struct(Visitor *v, Error **errp) GHashTableIter iter; GQueue *any; - if (ov->depth > 0) { + if (ov->depth > 1) { return; } @@ -276,8 +276,8 @@ static void opts_check_list(Visitor *v, Error **errp) { /* - * FIXME should set error when unvisited elements remain.
