Inside the generated code between visit_start_struct() and visit_end_struct(), we were blindly setting the error into the caller's errp parameter. But a future patch to split visit_end_struct() will require that we take action based on whether an error has occurred, which requires us to track all actions through a local err. Rewrite the visits to be more in line with the other generated calls. Signed-off-by: Eric Blake <eblake@redhat.com> --- v6: based loosely on v5 7/46, but mostly a rewrite to get the last generated code in the same form as all the others, so that the later conversion to split visit_check_struct() will be easier --- scripts/qapi-visit.py | 16 +++++++++++----- 1 file changed, 11 insertions(+), 5 deletions(-)
