WIP fuzz testing. Not super useful yet.

cargo install cargo-fuzz

Before first use:

cd fuzz
cargo run --bin=build_corpus

To fuzz stuff:

RUSTFLAGS='-C codegen-units=1' cargo +nightly fuzz run --release fuzz_sqllogictest -- -dict=fuzz/sql.dict

Failing tests are added to ./fuzz/artifacts/fuzz_sqllogictest and can be rerun with cargo test -p sqllogictest.

TODO(jamii): figure out why sqllogictest::test::fuzz_artifacts can't be run by name.

Before first use:

mkdir -p fuzz/corpus/fuzz_testdrive
cp -R test/* fuzz/corpus/fuzz_testdrive

To fuzz stuff:

RUSTFLAGS='-C codegen-units=1' cargo +nightly fuzz run --release fuzz_testdrive

Failing tests are added to ./fuzz/artifacts/fuzz_testdrive and can be rerun with cargo run --bin testdrive ./fuzz/artificats/fuzz_testdrive/<FAILING_TEST>.
