Missing version in META file

[hhugo]

Starting with lwt 5.8.0 (lwt 5.7.0 is fine), the version is missing from lwt META's files.

The version in the META can be queried by ocamlfind. Some packages query it to check their dependencies.

Actual behavior

$ ocamlfind query lwt -format %v
[unspecified]

Expected behavior

$ ocamlfind query lwt -format %v
5.{8,9}.0

In 5.7.0, the version was present in the opam files. I suspect, but I'm not 100% confident, that dune extracts this info to generate the META.

In 5.8.0 and above, opam files are generated from dune-project but dune-project doesn't contain any version info.

In js_of_ocaml, I use dune-release to release packages and dune-release distrib create an archive with a dune-project file updated with the correct version.

Thanks, I'll make a 5.8.1 and mark 5.8 as avoid-version in opam-repository.

I've made ocaml/opam-repository#27204 for https://github.com/ocsigen/lwt/tree/5.8.1

doesn't seem to fix the ocamlfind version…

I'll investigate when I have time

trying to add the package version information right into the dune-project file now

works for 5.8.1

I'll mark 5.8.0 as avoid-version, and do the same for 5.9
