Fuzz Test for GreptimeDB

Setup

  1. Install the fuzz cli first.
cargo install cargo-fuzz
  1. Start GreptimeDB
  2. Copy the .env.example, which is at project root, to .env and change the values on need.

Run

  1. List all fuzz targets
cargo fuzz list --fuzz-dir tests-fuzz
  1. Run a fuzz target.
cargo fuzz run fuzz_create_table --fuzz-dir tests-fuzz

Crash Reproduction

If you want to reproduce a crash, you first need to obtain the Base64 encoded code, which usually appears at the end of a crash report, and store it in a file.

Alternatively, if you already have the crash file, you can skip this step.

echo "Base64" > .crash

Print the std::fmt::Debug output for an input.

cargo fuzz fmt fuzz_target .crash --fuzz-dir tests-fuzz  

Rerun the fuzz test with the input.

cargo fuzz run fuzz_target .crash --fuzz-dir tests-fuzz
