Fuzzing

To run the fuzzer you can follow the instructions on: https://fuzz.rs/book/afl.html

Run fuzzing

To install AFL you can run cargo install afl --force. Due to some compatibility issues, on OSX, you should install a specific version (cargo install afl --force --version 0.4.1) until rust-fuzz/afl.rs#146 gets resolved.

Once you have AFL installed, you can start fuzzing with:

cargo afl build
cargo afl fuzz -i in -o out target/debug/parquet-fuzz

After founding some crashes or hangs, you can find the outputs on the out/crashes or out/hangs folder. Then, you can run this command on the root of the project to check the trace of the crash:

RUST_BACKTRACE=1 cargo run --bin parquet-read parquet-fuzz/out/crashes/{filename}
