node: manually implement Debug...
node: manually implement Debug I got too irritated today with the default Debug implementation of hg::revlog::Node while playing with a new parser. This isn't quite what I wanted, but it wasn't much code and it at least gives you output that's easy to visually compare to a node.hex()ed identifier from the Python side of things. Sadly, this doesn't influence the output in lldb or the VSCode debugger extension that uses lldb under the covers, but it at least means debug prints are a little more useful.

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
