There are issues with Windows. tox tests fail.

py27 runtests: commands[0] | nosetests
.................FFF................................EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE.EEEEEE

• setup AppVeyor @spderosso?
• fix Windows tests - https://ci.appveyor.com/project/spderosso/gitless-11bfm

I've setup appveyor (2a0b6a6) but we are missing something because the build fails before executing the tests.

The problem seems to be an access denied error on a temp file. If there's a Windows expert out there that wants to figure out what's going on that'd be awesome

Why libgit2 should be built from source? gitless just needs a wheel binary.

https://github.com/libgit2/libgit2/blob/master/appveyor.yml

[spderosso]

The script follows the installation instructions for pygit2. Pygit2 requires libgit2 to be installed and it seems like the preferred approach for installing libgit2 is to build it from source.

[techtonik]

@spderosso it is pygit2 bug then.

[spderosso]

Perhaps, but the build log says:

Installed c:\projects\gitless\.eggs\pygit2-0.25.1-py2.7-win32.egg

which suggests that pygit2 was correctly installed. Yet the file that is causing the error is the cffi backend, which is related to pygit2.

I am going to try to see if I can reproduce it locally.

[techtonik]

@spderosso what is the pip version? I'd expect it to build and install wheel and not egg.

[techtonik]

I filled libgit2/pygit2#714 to update Windows installation instructions. I see no need to rebuild pygit2 from source.

[techtonik]

Now tests on Python 3 fail because of pbs https://ci.appveyor.com/project/spderosso/gitless/build/1.0.12/job/0osex6dyvhxk9xx3#L71 with:

pbs.CommandNotFound: __path__

Either fork and patch https://github.com/techtonik/pbs or switch to tomerfiliba/plumbum#332

I abandoned bad habit of using Windows, so feel free to pick up this issue.

GL works with Cygwin on Windows, but native support via binary wheels is the way to go.
