crepererum commented on issue #1529: ARROW-1589: [C++] Fuzzing for certain
input formats
URL: https://github.com/apache/arrow/pull/1529#issuecomment-362577439
I've reworked the source file organization as @wesm suggested. Also --- as a
nice side effect --- I've added a helper to add other fuzzing tests more easily
in the future (similar to the way arrow defines tests executables).
Regarding `libLLVMFuzzer.a` (@xhochy):
I've used [this
suggestion](https://github.com/kkos/oniguruma/wiki/How-to-make-libfuzzer-oniguruma-program-on-Mac-OSX)
some months ago, but I doesn't work anymore since libfuzzer was integrated
into `compiler-rt`. I think you can just build `compiler-rt` (you should figure
out where your `llvm-config` binary is) on it's own and use
`libclang_rt.fuzzer_osx.a` for that purpose (clone source from
[here](https://github.com/llvm-mirror/compiler-rt) and use the guide on [this
page](https://compiler-rt.llvm.org/) for compilation). Or you wait until the
next LLVM release where this is hopefully integrated by default.

> The arrow lib should have fuzzing tests for certain input formats, e.g. for
> reading record batches from streams. Ideally, malformed input must not crash
> the system but must report a proper error. This could easily be implemented
> e.g. w/ [libfuzzer|https://llvm.org/docs/LibFuzzer.html] in combination with
> address sanitizer (that's already implemented by Arrow's build system).
