narrow: move status-filtering to core and to ctx One of my recent changes from repo.status(ctx1, ctx2) to ctx1.status(ctx2) broke some of our Google-internal tests. The problem turned out to be that the narrow extension was overriding repo.status() to make it filter out paths outside the narrowspec. When I changed to ctx1.status(ctx2), then that filtering obviously got lost. ctx.status() seems like a better method to do the filtering in, so this patch moves the filtering into that method, thereby also moving it out of the extension and into core.

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
