Pushing changes to GitHub Pages branch removes custom domain setting

[febbraro]

I have travis building a documentation site with mkdocs and using the deploy provider pages to push to a gh-pages branch in the same repo. Everytime a new build pushes to the repo, the settings for "custom domain" get reset to blank.

I'm happy to look at code and help debug, etc. but I can't figure out where the code is that does it, etc.

I am setting the custom domain through the repo settings, not via a CNAME file.

Adding a CNAME file fixes this problem. Something to consider though is that GitHub recommends setting it via the Settings page and not via a CNAME file, so this may start to appear more and more.

See the "tip" here: https://help.github.com/articles/troubleshooting-custom-domains/#github-repository-setup-errors

If you set the fqdn setting for the pages deploy provider, it will create a CNAME automatically. Whatever you put in the CNAME should automatically populate the custom domain setting.

Note that this will remove the need for you to copy the CNAME file to the build directory.
