This series introduces visit_start_enum and visit_end_enum as a way of allowing visitors to trigger generated code to bail out on visiting union fields if the visitor implementation deems doing so to be unsafe.
See patch 1 for the circumstances that cause the segfault in the dealloc visitor. This is a spin-off of a patch submitted by Fam Zheng earlier. See the thread for additional background on why we're taking this approach: http://thread.gmane.org/gmane.comp.emulators.qemu/296090 Fam, if you'd like to break out your iotest into another patch I can include it as part of this series, otherwise it can be sent as a follow-up. include/qapi/visitor-impl.h | 2 ++ include/qapi/visitor.h | 2 ++ qapi/qapi-dealloc-visitor.c | 6 ++++++ qapi/qapi-visit-core.c | 15 +++++++++++++++ scripts/qapi-visit.py | 6 ++++++ tests/qapi-schema/qapi-schema-test.json | 10 ++++++++++ tests/qapi-schema/qapi-schema-test.out | 3 +++ tests/test-qmp-input-strict.c | 17 +++++++++++++++++ 8 files changed, 61 insertions(+)
