• UI performance improvements

Detailed break down

Features typefeature

MVP: view source code rules organized by branches

• Deliverable %15.5 - Add branch rules details to the list of branch rules 2 frontend backend
• Deliverable %15.5 - Branch rules MVC: Display branch rules details 2 frontend backend

UX improvements

• Deliverable %15.4 will likely slip to %15.5 - Add ability to link to a line on File Blame page 2 frontend UX

Faster syntax highlighting using Highlight.js

• This is not a very high priority. However, if some of those frontend issues marked as 'might slip' get finished in %15.4 after all, we can replace them with issues from Link to package managers when viewing dependency files with highlight.js pulling from the top.

Helping others

• Deliverable spike %15.5 - Document how the LFS calculations work with forking
  • This spike is to prepare Forked repositories do not deduplicate LFS objects

Spikes to provide input to upcoming product decisions

• Deliverable spike %15.5 - to Determine how and where to count lines of code ... (gitlab#373712 - closed)
  • Supporting the assessment of Report number of lines per language in repository charts
• Deliverable spike %15.5 - Better display of tags and branches in commit view
  • The spike aims to analyze if/how we can make sure that the current functionality of showing tags and branches that contain the commit is also supported in bigger projects of the size of GitLab where you currently just get Branches unavailable Tags unavailable with a tooltip Project has too many branches/tags to search. This spike actually answers questions that relate to both these features:
    • Better display of tags in commits list view
    • Better display of tags and branches in commit view
  • The features are rather popular:
    • 5 big customers are asking for this
    • 62 upvotes
    • SUSFY22 Q1 - Incomplete

  • potential revenue loss

Maintenance typemaintenance

• Deliverable %15.5 - Improve caching on raw endpoints backend typemaintenance
  • Helping others that have a security issue due end of August
• Deliverable %15.5 - Add instrumentation for cache metrics backend typemaintenance
• Stretch %15.5 - Switch to google-protobuf v2 API 2 backend
• Stretch %15.5 - Convert `diffs/_file` partial into a ViewComponent (gitlab#321302 - closed) 3 backend

What we don't have to do in %15.5 (unless new issues of this type come up)

• For the first time in a very long-time we start a new milestone without having any open infradev, security, or availabilitylimit.
  • With one exception though: Blind SSRF in repository mirroring using DNS re... (gitlab#353018 - closed) is a security. However, it is currently workflowblocked by https://gitlab.com/gitlab-org/gitaly/-/issues/4266+. Unfortunately, the Gitaly team has reduced capacity due to an FCL & FedRAMP vulnerability work. Once it is unblocked @mparuszewski kindly volunteered to pick it up.
• With the recent improvements, we are no longer exceeding our Error budget.

Team Capacity

• Total Weight Capacity: 49
• FE Weight: 14
• BE Weight: 35
