conf-bash not detecting installed bash on OpenBSD

[jideelgh]

(OpenBSD 7.4, ksh)
conf-bash keeps asking to install bash every time "opam upgrade" is launched, while it's already installed.

I tried to let opam to install bash or to install it manually.
Bash is installed in /usr/local/bin/bash, I tried to symlink to /bin/bash, no success.
bash --version returns

GNU bash, version 5.2.15(1)-release (x86_64-unknown-openbsd7.4)
Copyright (C) 2022 Free Software Foundation, Inc.
[...]

I used ktrace to investigate some pledge/unveil issue, couldn't identify one.
I also tried to start opam w/ the --debug flag & adjusting the level with --debug-level flags, no obvious error message (except maybe "ocamlc not found", quite weird as ocamlc is well installed and reachable, may not be related).
(behavior identified because JaneStreet Base 0.16.0 added conf-bash as a dependency)

What version of opam are you using. Maybe some opam maintainer knows more, ping @kit-ty-kate @rjbou

I've transferred this issue to opam, where the issue most likely is.

[jideelgh]

@mseri opam 2.1.5

[kit-ty-kate]

@jideelgh what does pkg_info -mqP | grep bash give you?

[rjbou]

What is the output of opam var os-family?

[jideelgh]

@rjbou bsd

@kit-ty-kate shells/bash

ah it looks like it's my fault, i did an off-by-one error in https://github.com/ocaml/opam/pull/4396/files#diff-6c0a6590c49c5a229f469d627b9e9484f1b20c1fb5fb1c8102d64a3d2c1d09b6R187 ..

sorry about that

[kit-ty-kate]

Actually it's already fixed in 4b060e7 by @mndrix

You can fix this by using the latest beta:

bash -c "sh <(curl -fsSL https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh) --dev"

[rjbou]

Should we backport the fix in 2.1.6 ?

[mseri]

Good idea, it seems a small enough fix on a possibly common future error to warrant a backport

[kit-ty-kate]

Fair enough, I've backported the commit to #5870. We expect to release it a couple weeks after the next 2.2.0 beta.

I'll close this as it is fixed in master

Glad I could help. That was fast :) Thank you all.
