4 Zstd provides a fuzz corpus for each target that can be downloaded with
13 ## fuzz.py
15 `fuzz.py` is a helper script for building and running fuzzers.
16 Run `./fuzz.py -h` for the commands and run `./fuzz.py COMMAND -h` for
21 `fuzz.py` provides a utility to generate seed data for each fuzzer.
25 ./fuzz.py gen TARGET
44 Run `./fuzz.py build -h` for help.
48 `./fuzz.py` can run `libfuzzer`, `afl`, and `regression` tests.
50 Flags not parsed by `fuzz.py` are passed to the fuzzing engine.
53 Here's a helpful command to fuzz each target across all cores,
56 for target in $(./fuzz.py list); do
57     ./fuzz.py libfuzzer $target -jobs=10 -workers=10 -max_total_time=1000 || break;
60 Alternatively, you can fuzz all targets in parallel, using one core per target:
62 python3 ./fuzz.py list | xargs -P$(python3 ./fuzz.py list | wc -l) -I__ sh -c "python3 ./fuzz.py li…
70 # Build the fuzz targets
71 ./fuzz.py build all --enable-fuzzer --enable-asan --enable-ubsan --cc clang --cxx clang++
73 CC=clang CXX=clang++ ./fuzz.py build all --enable-fuzzer --enable-asan --enable-ubsan
75 ./fuzz.py libfuzzer TARGET <libfuzzer args like -jobs=4>
85 CC=clang CXX=clang++ ./fuzz.py build all --enable-fuzzer --enable-msan
86 ./fuzz.py libfuzzer TARGET <libfuzzer args>
89 `fuzz.py` respects the environment variables / flags `MSAN_EXTRA_CPPFLAGS`,
99 # Build the fuzz targets
