Windows support 2

https://github.com/sdg-mit/gitless/issues/13#issuecomment-302825930

There are issues with Windows. tox tests fail.

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

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

[spderosso]

I've setup appveyor (2a0b6a6fc54f0836c79751cdedede6c890704382) 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

[techtonik]

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 https://github.com/libgit2/pygit2/pull/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 https://github.com/tomerfiliba/plumbum/issues/332

[techtonik]

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

[ArneBachmann]

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

[SpecialAgentX]

Are there any plans to get a running windows version? I‘d like to use it, but I need to use Windows 7 at my work.

Thank you!

[arigo]

I feel that I should note it here, but gitless seems to work fine on Windows after you install Python 2.7 (tested with the 32-bit version). Afterwards, just do: python -m ensurepip and python -m pip install gitless

[David-OConnor]

Any word on this? Python 2 has been obsolete for years, and is officially deprecated. Windows is a very popular OS. What's the limfac on releasing a Windows binary or something that runs on top of Py 3?

[techtonik]

@David-OConnor

1. Fix link to AppVeyor automatic tests after repo renaming - see README
2. Fix AppVeyor
3. Fix tests
4. Run tests on Python 3 to see what is broken

If you running Windows, you can run the tests and report results here.

[Ruffnik]

I'd like to help running tests on Windows (I'm developing in Delphi & CMD on Windows and the white papers on Gitless read like that's finally the solution to Git screwing with my source because I got some arcane detail wrong), but I have trouble getting started.

If someone would find the motivation to get a newbie willing to learn started, I'd be rather grateful.

[spderosso]

@NeoBoot With the new changes I just pushed, Gitless should now work on Windows if you have Python 3.8. See: https://ci.appveyor.com/project/spderosso/gitless-11bfm

Can you or anyone else using Windows check that it works? You can follow the instructions on the README file to install from source and run the tests. There appears to be a problem with Windows+Python 3.7, which I might be able to take a look at later this week.

[ArneBachmann]

Using a Python 3.8 conda environment, I was able to install gitless, with a twist:

conda install "pygit2==0.28.2"
pip install gitless

Note that conda install pygit2 will install version 1.2.1 which collides with the pip package dependencies.

Running Gitless:

[spderosso]

Thanks! I didn’t cut a new release yet, so to try the new changes you need to clone the gitless repo, cd to the root of the repo and do ./setup.py install

Yeah that seems to work :-)

Same issue here.

pip install gitless fails with "ERROR: Failed building wheel for pygit2". (and running pip install pygit2 doesn't help)
