      Controversial opinion: what a waste of attention. We should have a declared range of versions (we attest) our libraries support, and separately a freeze file for reproducible test running (and other code executions, like runMain, console, what have you).https://twitter.com/fst9000/status/1227149976196845569 …

      This was a little bit over a year ago. @ScalaSteward has now created over 45k PRs of which 30k have been merged and it is watching nearly 1000 repos. At this pace, there will be over 100 000 merged PRs at the end of the year. 😱 https://twitter.com/fst9000/status/1081268315731963906 …

      It's a huge waste of attention, but orders of magnitude less than the waste of attention that would have been spent making those PRs manually. Though we shouldn't be deluded that the problem is now "fixed".

      Every solution to this problem boils down to one of those two. A non-persistent DAG, by definition, violates reproducibility in some form (note that freeze files simply choose a middle ground between the two extremes). A persistent DAG will be noisy without atomic updates.

      Replying to @djspiewak @dwijnand

      I think there's a good compromise though: We can have builds which are immutable and repeatable, but where nonbreaking changes can be introduced trivially with the user's intervention, and larger changes less trivially (but, as necessary). (Full explanation won't fit in a tweet.)

      I'm also against the idea of build files living in git repositories. It means you can't update the build (e.g with new dependencies) without changing the repo.

      Instead, I want a file in the repo which points to the repeatable build which was known to work for that version of the code, but which can be trivially updated to the latest version published post-hoc which claims to be backwards compatible with that version.

          So you want to replicate Git's immutable Merkel Tree machinery… but in another tool that isn't git? Like I think I kinda see what you're getting at, but it's really just another variant of a "middleground" proposal towards removing persistence.
