lwt6 documentation failed to generate

[raphael-proust]

the documentation for lwt.6.0.0 (and related packages lwt_direct and lwt_runtime_events) is missing https://ocaml.org/p/lwt/6.0.0

looking at https://ocaml.org/p/lwt/6.0.0 and then https://sage.caelum.ci.dev/job/2026-01-12/143820-voodoo-prep2-96d2de it looks like the error is completely unrelated to lwt

what can i do to trigger a rebuild or otherwise make the documentation update on there

[raphael-proust]

small ping on this issue

is there something i can do to move things forward?

[cuihtlauac]

@jonludlam: Where should we migrate this issue?

[raphael-proust]

(Also, side issue, is there some documentation about where and how to report these kinds of issues?)

The documentation served by ocaml.org comes from another server: https://sage.ci.dev/current. This is generated by ocurrent/ocaml-docs-ci

@mtelvers @jonludlam : Should issues as found by @raphael-proust be reported to: https://github.com/ocurrent/ocaml-docs-ci ?

FWIW, lwt.6.1.0 also seem to have failed to generate: https://ocaml.org/p/lwt/6.1.0 and so did lwt_ppx https://ocaml.org/p/lwt_ppx/6.1.0

[raphael-proust]

i don't understand why it doesn't generate, the page https://sage.caelum.ci.dev/package/lwt.6.1.0 says it's blocked but it also says all the prep is ok

[jonludlam]

Sage has been having some difficulties since xmas. I pushed a fix last week, but it had some problems and was taking an extremely long time to build everything. I think I've now tracked down the problem it was experiencing and since yesterday it's been building and I can't see the same sorts of problems in the logs any more. Once everything has finished building I'll flip the switch and all the new docs will go live.

In short, apologies to @raphael-proust and everyone else who has been waiting on docs - but fingers crossed it should be fixed by next week!

[jonludlam]

OK, sage finished its big initial run and is now doing incremental updates, so I've flipped the switch and it's now serving the newly built docs. Consequently, lwt.6.1.0 has docs online. Thanks for your patience!
