Add support for OCaml 5.1 #428

tmattio · 2023-06-16T14:27:10Z

Update trunk AST for pvb_constraint
Add migration from 501 to 500
Bump the 501 AST magic numbers
Binary AST reader: use latest possible AST version

When the magic numbers aren't unique, before this commit, the binary AST reader would read into the first AST version matching the magic number. With this commit, it takes the last such version. That's important for trunk support.

Fix inline tests' dependency on OCaml version

Done by making the expected output also dependent on the OCaml version

This is cherry-picking 4ebc7d4 to 9d95d42. (with a small difference from 4ebc7d4 to remove the README update)

I've squashed the commits to make the history cleaner as most of the commits seemed to be fixes of the intial commit, but I can keep the history intact if you prefer.

I'll rebase trunk-support on top of main once merged.

Thanks for taking this on! There seem to be a few important commits from trunk-support missing (see below).

This is the version from before the compiler Parsetree fix for coercions, isn't it?

We also need a "not compatible with ocaml.5.1.0~alpha1" constraint here.

Thanks for the review @pitag-ha and you're right I had omitted commits that came after the support for 5.2 that fixed 5.1. I added e072b1c and 1966c31.

So the only commits from trunk-support that are included now should be:

Do any of these seem relevant for 5.1?

pitag-ha

Looks almost good, thanks! We just need to run and promote the tests to fix them on 5.1. Could you do that?

This last test will need to be updated when bumping the AST.

Done

pitag-ha

Thank you, looks all good (up to the still running CI)! Once the CI finishes and passes, let's merge this and then cut a release right away.

The cluster is having a hard time running the jobs - macOS x86 and Debian s390x have been hanging since yesterday.

Seeing all the other jobs are passing and we don't have an immediate solution for unlocking the hanging jobs, I'm merging now.
