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
