Port sqlite3 fuzzer #3

tanin47 · 2016-09-13T20:34:34Z

It needs fossil. Therefore, the build.sh looks weird.
I can't make sqlite3.a. So, I use sqlite3.o. I have no idea how they are different. (Not a C++ person here.)

I signed it!

Verified locally, it works. Also it's worth to add a dictionary. I'll add it.

I was actually waiting to merge this because I knew that it wouldn't actually work on our builder, but should be fine to keep it checked in for now.

I didn't know that, sorry! :)
Let's post comments for other pull requests, if there are any blockers for merging.

I got a feeling there's an ordering issue. Looking at the error logs [https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=56500#c2](https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=56500#c2) there appears to be an issue where we're throwing exceptions before the coverage completes. ``` === Uncaught Python exception: === -- | MaxRetryError: HTTPConnectionPool(host='localhost', port=8011): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f4cdf33d1f0>: Failed to establish a new connection: [Errno 101] Network is unreachable')) | Traceback (most recent call last): | File "fuzz_requests.py", line 109, in TestOneInput | File "urllib3/_request_methods.py", line 118, in request | File "urllib3/_request_methods.py", line 217, in request_encode_body | File "urllib3/poolmanager.py", line 433, in urlopen | File "urllib3/connectionpool.py", line 874, in urlopen | File "urllib3/connectionpool.py", line 874, in urlopen | File "urllib3/connectionpool.py", line 874, in urlopen | File "urllib3/connectionpool.py", line 844, in urlopen | File "urllib3/util/retry.py", line 505, in increment | MaxRetryError: HTTPConnectionPool(host='localhost', port=8011): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f4cdf33d1f0>: Failed to establish a new connection: [Errno 101] Network is unreachable')) | | INFO: Instrumenting 3854 functions... | INFO: Instrumentation complete. | ==10674== ERROR: libFuzzer: fuzz target exited | #0 0x7f4ce0bac694 in __sanitizer_print_stack_trace /src/llvm-project/compiler-rt/lib/ubsan/ubsan_diag_standalone.cpp:31:3 | #1 0x7f4ce0b2df48 in fuzzer::PrintStackTrace() /src/llvm-project/compiler-rt/lib/fuzzer/FuzzerUtil.cpp:210:5 | #2 0x7f4ce0b12cdc in fuzzer::Fuzzer::ExitCallback() /src/llvm-project/compiler-rt/lib/fuzzer/FuzzerLoop.cpp:250:3 | #3 0x7f4ce09068a6 in __run_exit_handlers /build/glibc-SzIz7B/glibc-2.31/stdlib/exit.c:108:8 | #4 0x7f4ce0906a5f in exit /build/glibc-SzIz7B/glibc-2.31/stdlib/exit.c:139:3 | #5 0x7f4ce03b2c78 in libpython3.8.so.1.0 | #6 0x7f4ce03b76cf in libpython3.8.so.1.0 | #7 0x403ad2 in fuzz_requests.pkg | #8 0x403e67 in fuzz_requests.pkg | #9 0x7f4ce08e4082 in __libc_start_main /build/glibc-SzIz7B/glibc-2.31/csu/libc-start.c:308:16 | #10 0x40249d in fuzz_requests.pkg | | SUMMARY: libFuzzer: fuzz target exited ``` This is an attempted fix inspired by the requests [fuzz_server.py](https://github.com/google/oss-fuzz/blob/master/projects/requests/fuzz_server.py) where the lifecycle of the test thread is managed within the server. Since the web server is created at the start of `TestOneInput` I don't expect there to be any timing issues or thread initialisation issues.

As the test suite currently fails building for coverage due to this error: ``` Step #3 - "compile-libfuzzer-coverage-x86_64": CXXLD plist_test++ Step #3 - "compile-libfuzzer-coverage-x86_64": /usr/bin/ld: .libs/plist_test++: hidden symbol `atexit' in /usr/lib/x86_64-linux-gnu/libc_nonshared.a(atexit.oS) is referenced by DSO Step #3 - "compile-libfuzzer-coverage-x86_64": /usr/bin/ld: final link failed: bad value ``` I thought I'd add an option to allow disabling building those - and use this option here - since the test case binaries are not really required for fuzzing.

This fixes compilation errors of the form: ``` ...
