debuginstall extension support
  $ hg debuginstall --config extensions.fsmonitor= --config fsmonitor.watchman_exe=false | grep atchman
  fsmonitor checking for watchman binary... (false)
   watchman binary missing or broken: warning: Watchman unavailable: watchman exited with code 1
Verify the json works too:
  $ hg debuginstall --config extensions.fsmonitor= --config fsmonitor.watchman_exe=false -Tjson | grep atchman
    "fsmonitor-watchman": "false",
    "fsmonitor-watchman-error": "warning: Watchman unavailable: watchman exited with code 1",

Verify that Mercurial is installable with pip. Note that this MUST be
the last test in this file, because we do some nasty things to the
shell environment in order to make the virtualenv work reliably.

On Python 3, we use the venv module, which is part of the standard library.
But some Linux distros strip out this module's functionality involving pip,
so we have to look for the ensurepip module, which these distros strip out
completely.
On Python 2, we use the 3rd party virtualenv module, if available.

  $ cd $TESTTMP
  $ unset PYTHONPATH

#if ensurepip network-io no-pyoxidizer
  $ "$PYTHON" -m venv installenv >> pip.log

Hack: Debian does something a bit different in ensurepip.bootstrap. This makes
it so that pip thinks the 'wheel' wheel is installed so it can build wheels;
when it goes to try, however, it shells out to run `python3 -u <setup.py>`,
that *doesn't* get the 'wheel' wheel, and it fails with an invalid command
'bdist_wheel'. To fix this, we just delete the wheel from where Debian put it in
our virtual env. Then pip doesn't think it's installed and doesn't try to build.
  $ rm installenv/share/python-wheels/wheel-*.whl >/dev/null 2>&1 || true

Note: we use this weird path to run pip and hg to avoid platform differences,
since it's bin on most platforms but Scripts on Windows.
  $ (syshgenv; ./installenv/*/pip --no-cache-dir install $TESTDIR/.. >> pip.log)
