Builds are failing on appveyor because it's trying to install `noiseprotocol`
all the time, when it's only installable under py3.
Thanks to @julian and julian/jsonschema 's .appveyor for the hints.
Python.org is still supporting 3.4, but the lastest pypiwin32 stopped
providing binary wheels for windows for 3.4, so we can't run the appveyor CI
tests any more. It might still work there, but you'll have to find a way to
build pypiwin32 yourself.
We still support py3.4 on non-windows platforms.
The windows-specific bugfix we needed is now in the current Tox release,
so we no longer need pre-release code. Anyways the upstream git repo
moved (from bitbucket to github), so the install-from-bitbucket was
failing.
The .appveyor.yml tells the tox.ini to install pypiwin32 directly,
rather than through a "twisted[windows]" extra. I wasn't able to get the
"extra" syntax to work properly under appyeyor, even though it worked ok
for me locally.
We use an extra "meta" tox environment to run "wormhole --version". This
confirms that versioneer is getting the right value, since we're now
running it from an installed sdist, rather than a checked-out git source
tree.
