Everyone, please give this a try. It should be the last stop before v1.17.0 final.

Is livebook and it’s dependencies ready for Erlang 27? I’m getting an error when trying to call escript.install task, see:

That’s a bug in the iso8601 package. Check out it issues tracker.

Eiji · June 4, 2024, 6:58am

Oh, looks like they have used naming that was not used before Erlang 27. I was worried that I messed up something with my Erlang installation.

There is almost 2 months old PR for that:

dfalling · June 5, 2024, 12:27pm

Are there plans to address —warnings-as-errors failing for dependencies? That was my only issue trying to migrate to 1.17.0.

olivermt · June 6, 2024, 6:20pm

Compile deps first with deps.compile ?

josevalim · June 6, 2024, 7:33pm

–warnings-as-errors does not apply to dependencies but I assume that, while your code is compiling, Absinthe code generation is emitting errors. In that case, you need to report it. Was an issue already reported?

dfalling · June 6, 2024, 7:51pm

It’s already been patched (but not yet released) in Absinthe thanks to @doughsay in #1318. But this didn’t previously cause --warnings-as-errors to fail before. It was suggested by sabiwara that maybe this is caused by metaprogramming.

This is the only lib in my codebase that was adversely affected by 1.17. Should I report a ticket in Elixir as well?

nocivus · June 7, 2024, 2:36pm

No support for the type syntax with $ yet, right?

josevalim · June 7, 2024, 6:46pm

It is not an Elixir bug. Because of meta-programming, the code is effectively part of your app, Elixir cannot know otherwise (unless the code was annotated - which wasn’t and then it requires a library patch anyway).

Warnings that arises when compiling deps (not your code), does not cause --warnings-as-errors to fail.

josevalim · June 7, 2024, 6:47pm

Nope. Probably 3 or 4 releases ahead of us still.

dfalling · June 7, 2024, 11:28pm

Interesting, because this compiled fine before. Maybe 1.17 fixed a big that let this slide under the radar before?
