dev meeting 2026 04 01

Agenda

• Post-action dependency refinement (Ali)

  • We (Tarides) want to make changes to the engine to allow for rules to optionally refine their dependencies
  • The refined dependencies will then be included in the target hash
  • Doing so allows rules to refine their dependencies and choose how their targets become invalidated
  • This will be an engine change which will be used by guarded experimental rules
    • One based on ocamlobjinfo processing
    • Maybe others

• When encountering (sandbox always) why do we choose copy and symlink over hardlink? (Ali)

  • Should we be preferring hardlink all the time?
  • Question came up adding hardlinking sandboxes to Windows https://github.com/ocaml/dune/pull/13987

• Formatting multi-line strings (Ali)

  • https://github.com/ocaml/dune/pull/13758
  • is this something we want, should we have a look at it?
