revisions: when using prefixhexnode, ensure we prefix "0" Previously, if using `experimental.revisions.disambiguatewithin` (and it didn't include rev0), and '0' was the shortest identifier in that disambiguation set, we printed it as the shortest *without* a prefix. This was because we had logic to determine "if the prefix is a pure integer, but starts with 0, we don't need to prefix with 'x': 01 is not a synonym for revision #1", but didn't handle the case where prefix == 0 (which is a pure integer, and starts with 0... but it *is* "rev0").

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
