Fuzz Test for GreptimeDB
Setup
- Install the fuzz cli first.
cargo install cargo-fuzz
- Start GreptimeDB
- Copy the
.env.example, which is at project root, to.envand 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
- List all fuzz targets
cargo fuzz list --fuzz-dir tests-fuzz
- 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.
