Migration Analysis: ProjectsController#show

~Conversation: #220 (closed)

Goal: perform a migration analysis on the ProjectsController#show controller in GitLab-Rails.

• Routes:
  • ProjectsController#show
  • ProjectsController#show.json

---

Three methods on Gitlab::Git::Repository, all cached in Rails.cache:

• root_ref (already migrated)
• branch_count
• tag_count

Proposal: implement CountRefs RPC that takes a 'prefix' argument (e.g. refs/heads/).
