This imply a refactoring of post-receive hook. As of today it's a mix of shell + perl + php. With the refacto we will have:

  • Launch grokmirror updates
  • Loop over the revs to trigger ci jobs, update push count, etc.

• make use of existing infra for truncated email sending
• "exec" the current shell script for regular notifs
