I'm looking at the idea of implementing native support for Pagure's webhooks in OpenShift as Fedora continues to adopt OpenShift for applications in its infrastructure.

However, there are a couple of deficiencies with our existing webhook format:

• We cannot tell what type of webhook it is from the header (no X-Pagure-Webhook-Event) which makes filtering events very expensive
• We do not have some basic information about commits included in any event that includes commit info (such as author, committer, author and commit date, and commit message)

The overall issue is that our webhook format is not even specified. It's instead part of the fedmsg documentation, which is rather problematic since it means we're dependent on fedmsg formatting for webhooks.

We should extend our webhooks to provide detail similar to what GitHub offers or similar to what GitLab offers.

We don't necessarily have to have the same format, but being broadly compatible in content with GitHub is useful so that if a GitHub API shim would be desired, it could be easily done.
