Hello,

In which case do users have to =E2=80=98rm -rf ~/.cache/guix/substitute=E2=
=80=99?

That directory is only used by =E2=80=98guix weather=E2=80=99.  In that cas=
e,
=E2=80=98--clear-cache=E2=80=99 could be added to =E2=80=98guix weather=E2=
=80=99 maybe?

Now, ideally there would not be any cache-related option because the
cache would always be valid.  If it=E2=80=99s not, it would be nice to see =
how
that can be improved or mitigated.

Thoughts?

Ludo=E2=80=99.

Why?  Well, garbage collection is about automatic memory management and
cache is about efficiency of memory usage.  Therefore, it is appears to
me relevant to have an option =E2=80=9Cguix gc --clear-cache=E2=80=9D to fo=
rce the clean
of various caches.

Cheers,
simon

Hi Mathieu,

Thanks for the review!

Correct.

If they want to clear /var instead of ~/.cache, sure.

That sounds like a sane interface, if clearing =E2=80=98root=E2=80=99's cac=
he were=20
the intention?  How would you even do that without sudo,=20
privilege-wise?

OK.

The point was to have a little command I could ask other users to=20
run, that's guaranteed to clear the correct directory, and doesn't=20
involve a spooky rm (which saves some back-and-forth :-).

> Maybe "guix gc" would be a better place?

No, I'd rather not add yet another option to =E2=80=98guix gc=E2=80=99 that=
 has=20
nothing to do with GC.

Kind regards,

T G-R

Hello Tobias,

> Unlike =E2=80=98rm -rf ~/.cache/guix/substitute=E2=80=99 this respects XD=
G_CACHE_HOME.

This script is invoked by the daemon as root. In that context,
%narinfo-cache-directory is "/var/guix/substitute/cache", whereas when
run as an user it is likely: "~/.cache/guix/substitute".

That would mean that users need to run "sudo guix substitute
--clear-cache". Moreover this script is an internal undocumented tool,
so I'm not in favor of adding user commands to it.

Maybe "guix gc" would be a better place?

Thanks,

Mathieu

Unlike ‘rm -rf ~/.cache/guix/substitute’ this respects XDG_CACHE_HOME.

Use the --OPTION form for consistency with the existing ‘guix substitute’
interface, where other guix subcommands would prefer an ACTION.  This
subcommand really supports only one OPTION at a time, anyway.

* guix/scripts/substitute.scm (guix-substitute):
Add a new ‘--clear-cache’ option argument.
(show-help): Document it.
