[bug#37200] Acknowledgement ([PATCH] gnu: Add roswell.)

This is a work in progress.
In particular, I know of the libcurl issue with SSL_CERT_DIR.
Is the proposed workaround appropriate?

There are still a couple more issues that need fixing.

Hello Pierre,

Looks like this patch feel through the cracks…

Normally, it’s up to applications using libcurl to do the right thing,
which is (1) to check standard certificate locations like you did above,
and ideally (2) to check some environment variables.

Unfortunately some applications don’t do this (see for instance commit
489d16577e4a6ccc30f3719d9263900089edd842.)  In those cases, we usually
do what you did above.

In short, I think it’s a fine workaround.

Maybe you can drop the second paragraph since it’ll hopefully become
stale.  :-)

Thanks!

Thanks for the review!

After some discussion with upstream, it does not seem that Roswell can
be used without using a binary blob of SBCL:

https://github.com/roswell/roswell/issues/387

So I don't think that makes it a good fit for a Guix package.

A few options:

- Patch Roswell so that it takes Guix' SBCL instead of its own (could be
a lot of work).

- Patchelf the binary blob.

Thoughts?

It’s clear that “patchelf the binary blob” is not an option in Guix.

The description for Roswell says it’s a tool for “installing and
managing Common Lisp implementations”.  If its job is precisely to
download and run pre-built binaries, then perhaps that would require
significant changes in Roswell itself so that it patches the binaries it
downloads?

But then again, if Roswell is about downloading pre-built binaries, we
should be careful about what’s going on.  After all, that might be
partly redundant with what Guix does, except that those binaries it
downloads may be non-reproducible or may even lack and build recipe
altogether.

So… the story about these pre-built binaries raises a red flag for me,
and I’m not sure what can be done here.

Thoughts?

I initially wanted to package Roswell so that we can start packaging Lem
(https://github.com/cxxxr/lem) but Lem it turns out the Lem does not
need it anymore.

I guess "Roswell on Guix" can be dropped then.

OK.

Your call.  If you feel this way, feel free to close this bug.

We can always revisit the issue later if needed.

Thank you,
Ludo’.
