conformance

Conformance

protobuf.v is validated against the official protobuf conformance suite (the same conformance_test_runner that gates the C++, Go, and other implementations).

Result (proto3)

CONFORMANCE SUITE PASSED: 1468 successes, 4134 skipped, 0 expected failures, 0 unexpected failures.

• All 1468 applicable proto3 tests pass (100%), 0 unexpected failures.
• 4134 skipped: proto2, editions, and the text-format / JSPB wire formats — all documented non-goals; the testee returns skipped for them.
• A few Recommended (optional, non-gating) cases remain — see failure_list.txt for the list; they surface only as warnings.

Running it

Needs cmake, ninja, and a C++ toolchain (to build the runner once), plus the V compiler.

VEXE=~/v/v ./run.sh

The script clones protobuf v34.1 (matching the pinned protoc), builds conformance_test_runner, generates conf_pb.v from the upstream conformance protos with vpbgen, builds testee.v, and runs the suite against failure_list.txt. Point PROTOBUF_SRC at an existing checkout to skip the clone.
