dummysmtpd: accept additional kwargs from stdlib smtpd This was causing extremely mysterious failures because smtpd is implemented using asynchat, which in turn doesn't appear to do anything *remotely* helpful if an exception occurs. # no-check-commit because I'm editing a foo_bar function signature test-patchbomb-tls.t now passes in Python 3, but only because it doesn't check message bodies like test-patchbomb.t. test-patchbomb.t is *full* of doubled headers in the output (eg [0]) which seems like an odd failure mode. 0: @@ -141,12 +154,17 @@ MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit + MIME-Version: 1.0 + Content-Type: text/plain; charset="us-ascii" + Content-Transfer-Encoding: 7bit Subject: [PATCH] bookmark X-Mercurial-Node: 8dab2639fd35f1e337ad866c372a5c44f1064e3c X-Mercurial-Series-Index: 1 X-Mercurial-Series-Total: 1 Differential Revision: https://phab.mercurial-scm.org/D4219

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
