dev meeting 20231004

Attendees: Rudi, Riku, Ali, Raja, Niclas, Marek

Updates

Rudi: Working on improvements on how we interface with the solver

Marek: fixing the multi-repo work

Opam-repositories

OPAM does not do any deduplication, there is just a global opam-repository. In dune-land we use a specific version of the repository per project, so that would lead to a lot of duplication.

Single version pinning

We need the user to provide us a version for pinned packages, and then we can remove all the other candidates from the list given to the solver. This way it will force that version.

Pining a package that depends on something not in the repo

Rudi will post an example in the Github issue.

dune install

What is it for and why doesn't @install do the same? dune install is not supposed to be used in OPAM files, it just directly copies files into the OCaml installation but doesn't let OPAM track what was installed.

Potential improvements: Print a warning when installing into an OPAM switch. Or use OPAM instead.
