rust-status: cap the number of concurrent threads to 16 During benchmarking it was determined that the use of more threads is very advantageous... until we use more than 16. This is most likely due to some resource contention (thrashing, etc.). Until we have time to figure out and fix the underlying cause, let's just cap at 16 threads.

How to add fuzzers (partially cribbed from oss-fuzz[0]):

  1. git clone https://github.com/google/oss-fuzz
  2. cd oss-fuzz
  3. python infra/helper.py build_image mercurial
  4. docker run --cap-add=SYS_PTRACE -it -v $HG_REPO_PATH:/hg-new
    gcr.io/oss-fuzz/mercurial bash
  5. cd /src
  6. rm -r mercurial
  7. ln -s /hg-new mercurial
  8. cd mercurial
  9. compile
  10. ls $OUT

Step 9 is literally running the command "compile", which is part of the docker container. Once you have that working, you can build the fuzzers like this (in the oss-fuzz repo):

python infra/helper.py build_fuzzers --sanitizer address mercurial $HG_REPO_PATH

(you can also say "memory", "undefined" or "coverage" for sanitizer). Then run the built fuzzers like this:

python infra/helper.py run_fuzzer mercurial -- $FUZZER
