Hey Guix,

Some context first. Nscd is a daemon distributed through Glibc originally used
to cache the potentially expensive NSS requests. NSS modules are usually
distributed as shared libraries that are DL-opened at runtime by the programs
linked against glibc. This interface is unstable, Glibc advise to always build
the NSS modules with the same Glibc version the host system uses. This is
obviously an issue for us: a single system closure can contain programs built
against different Glibc versions.

In Guix, we're mis-using Nscd to provide a ABI compatibility layer to load NSS
modules for programs built against a different GLIBC version than the system
one. Nscd is set with a TTL to 0 to disable the caching feature of the
original tool. While this works fine most of the times, it sometimes still
caches failed domain names resolution. It happens quite often While switching
between wifi networks for instance.

Nsncd is a non-caching Nscd replacement. It was originally written

NixOS adopted this Nscd replacement last year. This migration solved the
unwanted caching issues there.

This patch introduces the Nsnncd package and modifies the current Nscd service
adding a flag to use Nsncd instead of Nscd. This flag is disabled by default.

Package-wise: I had to introduce a bunch of packages to please the Cargo
version resolver. I'm a upstream contributor, I can probably relax those later
on. I was a bit shy to bump rust-nix for all the packages, I just introduced a
new version of it.

Service-wise: I introduced a new flag in the Nscd service instead of creating
a new Nsncd service from scratch to keep the existing service dependency
graph. It does not make 100% sense because Nsncd does not share the same CLI
API with Nscd. Nsncd actually does not support any configuration file. 🤷

Picnoir (7):
  gnu: Add rust-libc-0.2.153.
  gnu: Add rust-nix-0.28.
  gnu: Add rust-dns-lookup-2.
  gnu: Add rust-temp-env-0.3.
  gnu: Add rust-slog-async-2-8.
  gnu: Add nsncd.
  gnu: services: nscd: add Nsncd optional support.

* gnu/services/base.scm (services: nscd: add Nsncd optional support): Add a
new nscd-use-nscd? field in the Nscd configuration record. When set to #t, the
nscd service will use Nsncd in place of the Glibc's Nscd. I'm not 100% sure
adding this to the existing Nscd service is a good idea, it's however the most
convenient option for now. Or is it? :)

Howdy Picnoir,

Thanks for the patch set!  As you write, nsncd is going to be very
useful for Nix and Guix, so this is a much welcome addition.

picnoir@alternativebit.fr skribis:

I applied everything but the last patch.  I took the liberty to tweak
descriptions as per our guidelines¹, adding me as co-author.  I also
changed the ‘version’ field of nsncd to remove the “unstable-” prefix.
Let me know if anything’s amiss.

As for the last patch, I’ll comment separately.

Thanks,
Ludo’.

Well, there needs to be a flag somehow.  :-)

Nitpick: could you describe the changes at a syntactic level in the
commit log?  I know our conventions aren’t common today, so whoever
commits it can eventually tweak it on your behalf if needed.

> +  (use-nsncd?  nscd-use-nsncd?                     ;boolean
> +               (default #t))

I’m tempted to make it:

  (implementation nscd-implementation (default 'glibc))

And thus 'nsncd would be the other supported value.

Do you think that makes sense?

Anyhow, could you adjust doc/guix.texi to mention the new field?

Apart from that, the patch looks good to me.  Could you send an updated
version?

Thanks!

Ludo’.
