confirm-level=ask is actually yes?

[vphantom]

I can't figure out what I did to trigger this, or if it's actually a bug in 2.1.0, but --confirm-level=yes is assumed by default in my setup. If I use --confirm-level=ask explicitly to try to get the old behavior, it incorrectly behaves as though I had specified yes. If I use --confirm-level=no however, then no is correctly assumed.

I'm not running opam through a wrapper script which might make it think the tty is non-interactive.

Any ideas?

$ set |grep OPAM
OPAM_SWITCH_PREFIX=/home/lis/.opam/4.13.1+musl+flambda
$ if tty -s; then echo Interactive; else echo Non-interactive; fi
Interactive

What is the command that gets you this behaviour?

[vphantom]

It's across the board. For example opam install sexp will go right ahead and assume "yes" at the "13 to install, do you want to continue?" prompt.

[rjbou]

if yes is activated by --confirmlevel, --yes, or environment variable, you shouldn't have the prompt Do you want to continue?

$ opam install sexp

Weird. In my case I always see the prompt, but it is answered automatically. I can't seem to convince opam that I want interaction.

[kit-ty-kate]

Reading the code for this, I think the issue is that somehow on your machine you’re hitting some kind of Unix exception https://github.com/ocaml/opam/blob/master/src/core/opamConsole.ml#L757
As to why, i have no idea. If you’re feeling up to it you can try adding logs to this function and see what breaks but without knowing what is different on your system I have no idea how to debug this.

By any chance, how did you install opam? Through the precomiled binaries/install.sh or something else?

[vphantom]

I initially used the install.sh but I think that for the upgrade to 2.1.0 I just downloaded the prebuilt binary from GitHub. A binary diff confirms that it's the binary I'm currently using.

Of note is that I use kitty as my terminal and do everything in tmux. I have the relevant files for both in my ~.terminfo/. This was already the case when I used opam <2.1.0 and interactive prompts worked as expected.

If we prepare a branch, is it possible for you to test it?

[vphantom]

I don't understand the instructions at that page. The "From Source" section doesn't mention any compiling step.

But yes if there's something I can A/B test vs 2.1.0 I'd be happy to help. 😃

[rjbou]

It's normal that there is no compilation step. As you install everything with your opam, you don't need to compile things yourself :)
I'll prepare you a branch to test then.
