…platforms not on Windows elm_playground_web uses js_of_ocaml directly (Typed_array) and vdom does not bring it: the package, and elm_playground_3d_web and _webgl on it, failed wherever nothing else had installed it. caps said by the two packages that use it directly. The packages implementing a virtual library (the platforms, and tinybox on them) do not build on Windows, as elm_playground_native already says: dune's check of the implementation fails there (ocamlobjinfo, 0xc0000135).

The lower-bounds job built elm_playground_3d_opengl with dune 3.10.0, which does not find the implementation of a virtual library among the installed packages (3.17.2 does). On Fedora, tiny_libs' TLS tests found no openssl program.

0.3.1 fixes what this CI found in 0.3.0 that the opam files could not: tinybox's build failing on a file gone while its generator walks the build tree (ar's temporary files), and tiny_libs' socket tests failing where a sandbox forbids sockets.

tsdl 1.3.0 binds SDL_RenderGetWindow (SDL 2.0.22), looked up when a program starts; Ubuntu 22.04 has an older SDL.

One of them failed on a shared builder (ppc64, OCaml 5.5): a ratio of two running times, asserted. The tests skip themselves when CI is set. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

I think the other errors seems to be all in "experimental" CI test, so they are probably ok to fail.

mtelvers · 2026-10-01T11:42:46Z

I've fixed the issue in the CI test on the ppc64 build in mtelvers/day10@795b46c. This was a write/rename ordering issue.

From what I can see, the s390 failure is a genuine cross-architecture difference in floating point. I see that you already use 1e-12. 1e-6 would clear the error, or accept the discrepancy on this hardware.

The other CI failures are due to the tests waiting a fixed period for the service to start. e.g. pump ... 50 gives a 50ms start-up delay. On a build worker which may be slow or contended, this may not be enough time.

What opam's CI found in 0.3.1: the socket tests wait for what they expect instead of a fixed 50 ms; a floating-point check that was off by 1.5e-7 on s390x is made to a millionth. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

This opam-ci is hard to satisfy ...

aryx · 2026-10-01T18:27:20Z

tough guy

aryx · 2026-10-02T21:00:24Z

ok the error seems outside this package now, a curl issue I have nothing to do with.

aryx · 2026-10-03T16:15:13Z

@shonfeder what is the "needs reporter action" label? I think the remaining errors in opam-ci are ok no? We could merge this?

+bug-reports: "https://github.com/aryx/ocaml-elm-playground/issues"
+depends: [
+  "ocaml" {>= "4.14.0"}
+  "dune" {>= "3.0" & >= "3.17"}


Suggested change

"dune" {>= "3.0" & >= "3.17"}

"dune" {>= "3.17"}

I suggest cleaning up these double bounds - both here and in the other files. They arise because you both have a (lang dune ...) bound and an simultaneously list a dune dependency. I suggest removing the latter and regenerating the .opam-files, rather than me suggesting 14 manual edits or you doing 14 manual edits...

+# claude: not on Windows (as elm_playground_native): dune's check of a
+# virtual library's implementation fails there (ocamlobjinfo exits with
+# 0xc0000135, opam's Windows CI, 0.3.0); tiny_libs, tiny_languages,
+# tiny_appkits, elm_playground and elm_playground_3d build on it


These Claude comments bug me a bit:

No need to list claude: as you are responsible for the PR and release

It mentions "a virtual library's implementation" but not which one, so it is not very informative ("oh sdl/gl/foobar doesn't work on Cygwin/MSys2") nor very actionable ("let me try to get sdl/gl/foobar working on Cygwin/MSys2")

Repeatedly listing tiny_libs, tiny_languages, tiny_appkits, elm_playground and elm_playground_3d build on it as a comment in several other packages doesn't add anything

🤷

I forgot a fourth one (a nit I admit):

They also mention version 0.3.0, but now the PR's release version is at 0.3.5.
Since the remark concerns the enclosing package version, I'd just omit it.
A comment in packages/elm_playground_3d_opengl/elm_playground_3d_opengl.0.3.5/opam concerns 0.3.5 🙂

@shonfeder what is the "needs reporter action" label? I think the remaining errors in opam-ci are ok no? We could merge this?

Hi! Sorry for not being more explicit. It was because there were apparent CI tests failures in the packages at the time (which it seems you addressed after I added the label). This is just a tracking mechanism to coordinate between maintainers on what needs our attention.

aryx · 2026-10-04T06:28:09Z

I think it's ready for merge. The only remaining error in opam-ci looks unrelated.
