Homepage URLs are not updating

[jcoyne]

On the rubygems website, when a gem publishes new metadata in a gemspec, the homepage URL field in the sidebar is not updating.

As an example https://rubygems.org/gems/okcomputer,

The code was published from here: https://github.com/emmahsax/okcomputer/blob/main/okcomputer.gemspec#L22

so that link ought to go to https://github.com/emmahsax/okcomputer, instead https://github.com/sportsngin/okcomputer , right?

In addition, if spec.homepage and spec.metadata["homepage_url"] are both specified, and they are not identical, the metadata one wins over spec.homepage. This was surprising to me, and I expect would be to others.

On some projects I use the spec.metadata["homepage_url"] to provide an additional link to a project-related page or site. It turns out that this "additional link" turns up as the only homepage link on RubyGems.org, shadowing what I assumed was the primary spec.homepage.

Given this, it seems that rubygems should pick one of the following:

1. Raise an error when building a gem with a mismatch between the homepage urls
2. Display primary and metadata URLs, including multiple homepage URLs, if configured.
3. Document behavior for which takes precedence when both are present.

In addition, behavior differences between the ways of specifying homepage should be documented. For example, the integration of "GitHub stars" doesn't work when spec.homepage is the GitHub repo, but `spec.metadata["homepage_url"] is something else.

Also it seems intuitive for the GitHub stars integration to be able to link through spec.metadata["source_code_uri"], and/or the newer spec.metadata["github_url"]. This would free up the homepage url for a dedicated homepage, and still allow projects to show off their stars (or garner more of them).
