phabricator: allow local revisions to be specified with `phabupdate` It's way easier and less error prone to specify a revset after importing a series than to manually type in a series of Differentials. Unlike most revision oriented commands, this requires the `--rev` option explicitly because the existing `DREVSPEC` doesn't need to have the leading 'D', and therefore the meaning is ambiguous. I wouldn't have a problem giving precedence to the local revnum, but `phabread` and `phabimport` also use DREVSPEC, and local revisions make no sense there. I would be fine with modifying that definition to require the leading 'D', but I'm not sure how many people are used to not specifying it. Differential Revision: https://phab.mercurial-scm.org/D9356

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
