Upgrade to LTS 22.26 GHC 9.6.5 #5142

ChrisPenner · 2024-06-27T01:19:27Z

Overview

Upgrades to LTS 22.26; GHC 9.6.5

Recommended you update your local GHCup to: HLS 2.9.0.0 and Stack 2.15.5

Does someone who knows nix want to update the flake as well? It seems ghc 965 isn't being found, I'm sure it's an easy fix for someone who knows how it works 🙃

Implementation notes

Updates the LTS
Removes redundant applicative updates
Replaces use of NanoID lib with secure crypto instead, just cuz the NanoID lib has bitrotted
Move from x509-* to crypton-x509-* libs since HVR quit Haskell
Bump fuzzyfind
Removes a few custom pinnings now that they've been added to the snapshot

Interesting/controversial decisions

Not really

Test coverage

Existing tests

Loose ends

Should I fix the JWT lib deprecations now?

.github/workflows/bundle-ucm.yaml

+        with:
+          stack-version: 2.15.5


we can also change the default on unisonweb/actions/stack/install if we like that better.

Yeah, I figured it was a bit of a chicken-and-egg thing. TBH I kind of like specifying here because it's easy to see what it's using and easy to bump again in the future 😄

I'm glad you added it as an arg for that step.

Yeah, I like specifying it in this project too; I just wish we didn't have to specify it 4 times in this project, but maybe that's fine. Replace All.

You can read JSON in GH workflows, and also in Nix (I don’t know if there are other places we need versions).

So, we could write a dependency-versions.json file or something that the flake can read into its versions attrSet, and that workflows can read as well. I’ve been wanting to extract it from the flake anyway.

aryairani · 2024-06-27T02:52:37Z

Nice!

On testing, could you smoke test that the new file watch code works locally

I would normally agree with you, but haskell.nix (which is still used a lot by our flake) doesn’t support much in the way of GHC. But I’ll give it a shot.

+        ghc = "965";


This change doesn't actually work.

lib/unison-sqlite/src/Unison/Sqlite/Connection.hs

 -- This function does not support parameters, and is mostly useful for executing DDL and migrations.
 executeStatements :: Connection -> Text -> IO ()
-executeStatements conn@(Connection _ _ (Sqlite.Connection database)) sql = do
+executeStatements conn@(Connection _ _ (Sqlite.Connection database _tempNameCounter)) sql = do


This type just changed.

ChrisPenner · 2024-07-08T22:25:53Z

Ah, thanks Greg, yeah we can wait then. I'm getting pretty close with project roots now anyways :)

neduard · 2024-07-12T22:09:15Z

Hey @ChrisPenner , I was trying out this branch and I needed some changes from trunk so I had a go at merging it in & fixing the conflicts: neduard#3 - figured you'll probably encounter the same so it might be worth sharing in case it saves you a bit of time. As before feel free to either cherrypick or simply use as a reference.

Something worth pointing out is that I had to revert #5192 since numerals requires text (>=0.11 && <1.3) but LTS 22.26 has text 2.0.2 ( cc @aryairani ), but other than that the changes were minimal 🚀

@neduard I used allow-newer-deps: [numerals] for our stack build, because https://github.com/roelvandijk/numerals wanted containers (<6), so it probably accepted text-2.0.2 due to that flag, before the error was even on my radar. The author of numerals invites a PR with updated bounds, but I didn't have the time/knowledge to do it; but maybe you'd want to take a stab at it since you're more familiar with cabal than I am.

Otherwise, is there a similar directive to cabal to ignore the bounds on numerals (only)? I don't really want to revert #5192.

neduard · 2024-07-13T09:31:32Z

That's a much better shout @aryairani , thanks! I was so focused on getting it to build that I didn't think of other ways of solving it. I've raised the PR upstream and in the meantime worked around it by adding the following to contrib/cabal.project

allow-newer:
  numerals:text,
  numerals:containers

Okay great — neduard#3 is merged though, is that still where to look?

Thanks, @neduard. We really need to get a Cabal GitHub check into CI (even if it’s not required). It should generally be trivial to keep it in sync, but easy to overlook without a reminder.

Yeah, the Cabal Github check is missing a) because we didn't have anyone to maintain the .cabal file (no longer true) and b) because it would have doubled the resources needed to run CI (not fully true anymore, but not a non-issue either). I guess we could run cabal build on linux only; wouldn't have run tests. We should have some sort of build cache.

I opened #5225 so we could avoid conflating this discussion (my apologies for starting it here), and so we have somewhere to point when it comes up again.

neduard · 2024-07-15T18:49:29Z

@ChrisPenner @aryairani #5224 ready for merge into this one (or directly into trunk if you so wish) 😊 - please have a look at the description as there's a couple of things I'm unsure regarding updating a few transcripts and the jit tests potentially being cached but still requiring a couple of small updates - hoping you'll know more!

Reviewing the last merge into unisonweb#5142, I noticed some duplicated and out- of-date information. This brings things up-to-date and slightly reduces the duplication. - bumped Ormolu used by ci.yaml from 0.5.2.0 to 0.7.2.0, to match flake.nix - removed Markdown that claimed ci.yaml was using Ormolu 0.5.0.1 - moved description from `base-codebase` in Markdown to comment on `runtime_tests_codebase` in ci.yaml (and updated it to refer to builtin-tests/interpreter-tests.md instead of builtin-tests/base.md) - removed `unison_src_test_results` as it’s no longer managed as a single variable - moved other comments from Markdown to ci.yaml - added Markdown recommending to look in ci.yaml for specifics - rearranges the order of vars in ci.yaml to match the order they were presented in Markdown One thing I wasn’t sure how to map over: Markdown claims Racket 8.7 is used in CI, but ci.yaml doesn’t mention any Racket version.

With unisonweb#5142, Ormolu was upgraded from 0.5.2.0 to 0.7.2.0. This formats the codebase to avoid spurious formatting comingled in other commits. Almost all of the changes are simply wrapping single constraints in parens, like ```diff -hashBranch :: forall m. Monad m => Branch m -> m BranchHash +hashBranch :: forall m. (Monad m) => Branch m -> m BranchHash ``` There is also some reordering of language pragmas and imports, indentation correction (some of which gets precedence wrong), and switching some Haddock from `-- ^` to `-- |` .

This was mentioned in unisonweb#5142 (comment) but never made it in.

This seems to have been broken for almost a year. - Add missing packages to cabal.project - Allow newer `numerals` deps, as in Stack (this was mentioned in unisonweb#5142 (comment) but never made it in) - Disable `terminfo` flag for haskeline, as in Stack (eliminates a complaint about not finding libtinfo.so) - Add a constraint on text-builder, since 1.0.0 has been released, but is incompatible This also adds some comments and sorts the constraints list.
