Motivation for this change
  • Automate Dart updates with an updateScript. This produces sources.json which is parsed at eval time.
  • Dart updates also require updating top-level dart attributes with specific version names, which isn't consistent with other packages using multiple release channels/branches, and was missed for the last update. Remove these and pass the channel name to the derivation.
  • Rename the channel-specific dart attributes using kebab-case to be consistent with other packages. Aliases have been added to map the old snake_case names.
  • Remove dart_old as nothing in nixpkgs relies on it.
  • Update Dart versions:
    • stable: 2.7.2 -> 2.10.4
    • beta: init at 2.12.0-29.10.beta
    • dev: ->
Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits

@tadfisher Can you please fix the error ofborg has?

That ofborg failure looks like a conflict with #99920 which added these lines to pkgs/development/compilers/flutter/default.nix:

  dart_stable = dart.override { version = "2.10.0"; };
  dart_beta = dart.override { version = "2.10.0"; };
  dart_dev = dart.override { version = ""; };
  • Fix A: keep the dart/default.nix interface simple, and marry it to flutter/default.nix. Replace those lines in flutter/default.nix with the following (or something similar). Flutter and Dart derivations will probably have to be upgraded in lock-step. Each version of Flutter pins a version of Dart, so there are problems if they get out of sync. I'm not sure it has to be an exact match though.

      dart_stable = dart.override { version = "stable"; };
      dart_beta = dart.override { version = "beta"; };
      dart_dev = dart.override { version = "dev"; };
  • Fix B: allow the caller (the Flutter derivation) to override sources, decoupling the Dart derivation so that it can be updated independently. Flutter could even use the same script, modified/extended, given a set of Flutter-Dart version pairs. You can get those versions with something like this:

    git clone &&
    cd flutter &&
    for channel in stable beta dev ; do
      ./bin/flutter channel $channel
      git clean -xdf && ./bin/flutter ugprade 2>&1 | tee ../$channel.upgrade.log

    Within the past few days, the results were:

    • Flutter stable 1.22.5 -> Dart stable 2.10.4
    • Flutter beta 1.25.0-8.1.pre -> Dart beta 2.12.0-133.2.beta
    • Flutter dev 1.26.0-1.0.pre -> Dart dev

I can send a pull request to your pull request if that'd help? I've got time this week.
