rust-nodemap: automatically use the rust index for persistent nodemap The persistent nodemap requires the rust index to be used to provides any gains. So we automatically enable it for revlog using the persistent nodemap. We keep it off for other revset because now that the rust revlog fully initialise the nodemap using it everywhere introduce a fairly significant regression (eg: hg diff moving from 0.8s to 2.3s on mozilla-try) Differential Revision: https://phab.mercurial-scm.org/D8164

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
