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.

For stable fuzz tests

Set the GreptimeDB MySQL address.

GT_MYSQL_ADDR = localhost:4002

For unstable fuzz tests

Set the binary path of the GreptimeDB:

GT_FUZZ_BINARY_PATH = /path/to/

Change the instance root directory(the default value: /tmp/unstable_greptime/)

GT_FUZZ_INSTANCE_ROOT_DIR = /path/to/

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 -D -s none

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 -D -s none

Rerun the fuzz test with the input.

cargo fuzz run fuzz_target .crash --fuzz-dir tests-fuzz -D -s none

For more details, visit cargo fuzz or run the command cargo fuzz --help.
