import-checker: allow symbol imports from mercurial.pycompat...
import-checker: allow symbol imports from mercurial.pycompat Currently, the source transformer inserts `from mercurial.pycompat import delattr, getattr, hasattr, setattr, open, unicode` to the top of every file. As part of getting rid of the source transformer, we'll need to have source code call these wrappers directly. Rather than rewrite all call sites to call pycompat.*, I think it makes sense to import needed symbols via explicit imports. That requires loosening the import checker to allow this.

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
