First guess is that index = Index() resource needs to be freed.

It looks like @fourplusone has already worked on this, see:

• https://github.com/fourplusone/pygit2/tree/fix/windows-tests
• https://ci.appveyor.com/project/fourplusone/pygit2

[fourplusone]

Indeed, however lots tests are still failing :( It seems mostly related to files not being closed at the end of the test

[techtonik]

Even partial fix is good. I can help only one by one.

[jdavid]

I have merged branch fourplusone/fix/windows-tests from @fourplusone and errors are down to 7 from 146

But the build is green, it should be red since there are still 7 errors, @fourplusone do you know why it is green now?

[fourplusone]

try { & $env:PYTHON setup.py nosetests --with-xunit } catch {} in appveyor.yaml catches all errors during the test. maybe one should remove the try...catch... statement

[jdavid]

Thanks @fourplusone , it's red now. Do you know how to trigger a build automatically on every push to master?

[fourplusone]

This should be done automatically

From https://www.appveyor.com/docs/:

For every project AppVeyor will configure webhooks for its repository to automatically start a build when you push the changes. For every private project AppVeyor will add an SSH public key (deployment key) to the clone repository on the build machine.

[techtonik]

It makes sense to enable AppVeyor test for pull requests too http://help.appveyor.com/discussions/questions/203-auto-run-tests-on-pull-requests

This requires access to the pygit2's settings page at github, which I don't have. So this will have to be handled by someone else, @carlosmn can you do this? Or may be give me the rights to manage pygit2's settings.

Only 7 tests left - https://ci.appveyor.com/project/techtonik/pygit2/build/1.0.12/tests
