Ah, I understand now.
So the example you provided is a user-defined policy to install the
latest version of Guix that is downloadable using substitutes (if guix
publish has published those already).
As you say, in a similar vein, the end user could for themselves define
a policy that searches for a commit containing a specific successful
build, or a set of specific successful builds.

That makes sense, and is way better than I feared :-)

Your example helps visualize this, thanks.
Your example depends on there being a jobset that comprises the set of
packages you are interested in testing.
I imagine it is possible to do the same for an individual package / job.
The situation would be different if the end user wanted to perform a
similar operation for an arbitrary set of packages on their end.
It would probably involve something like this (probably naive):
(define (latest-commit-successfully-built-pkg pkg)
"Return the latest commit for the pkg for which substitutes are
(potentially) available."
;; Like your version, but magically performs query
;; for pkg, not the guix-modular-master evaluation
(let* ((evaluations (latest-evaluations pkg))
(candidates (filter-map (lambda (json)
(match (hash-ref json "checkouts")
((checkout)
(cons (hash-ref json "id")
(hash-ref checkout "commit")))
(_ #f)))
evaluations)))
(map (match-lambda
((evaluation . commit)
(and (evaluation-complete? evaluation)
commit)))
candidates)))
(any (match-lambda
((evaluation . commit) commit)
(apply lset-intersection equal?
;; Like latest-commit-successfully-built, but takes an
;; individual package name for which we return the
;; commit
(map latest-commit-successfully-built-pkg
%set-of-packages))))
Obviously the larger the set, the more requests are required, and the
lower the chance of a commit being available / a downgrade occuring

Interesting. Do you think this kind of thing might be useful to have in
the Guix manual? Like, in a section about a "typical" desktop end-user
might manage their system day to day?

The code below is an illustration of that. If you install it as
~/.config/guix/channels.scm, =E2=80=98guix pull=E2=80=99 will pull the late=
st commit
that was fully built on berlin.guixsd.org (see
<https://berlin.guixsd.org/jobset/guix-modular-master>), meaning that
substitutes for Guix itself should be available, unless =E2=80=98guix publi=
sh=E2=80=99
hasn=E2=80=99t =E2=80=9Cbaked=E2=80=9D them yet.
It takes two GETs and ~1s to do that here.

This sounds incredibly interesting =E2=80=94 and it is testament once again=
to
the power of Guix that this kind of solution could be feasible!
Thinking this through in my head somewhat, I had the following thoughts:
- This procedure is invoked client side, where the channel is defined
- That means the git searching is done client side, on every invocation
of guix (I guess this might be cacheable?)
- So the downside vis-a-vis a maintained "stable branch" would be a
price in performance as experienced by the end user
- The upside of course would be automatic curation of a stable branch
that saves a ton of volunteer effort and work
I have no idea what the performance cost would be. I guess you would
use "guix weather" to turn the set of requested packages into a manifest
which can then be checked with it.
So the cost would be one of the following scenarios:
Option a)
- fetch set of packages in a given commit
- query guix weather for 100% substitutes
- iterate until a match
- then perform the appropriate guix pull
Option b)
- perform a guix pull to the latest commit
- query guix weather for 100% substitutes
- until success, step back one step at a time through guix pull
(because of the cost of guix pull this seems unfeasible)
Option c)
Implement some form of substitute cache set querying on build farms, as
part of guix weather, so the 100% match is done on the build farm
instead of the client.
Dunno. There may be some things that already exist in Guix land that
I'm missing.
It's a super exciting approach for sure.

Right =E2=80=94 so at the very least it would have to prevent us going "bac=
k in
time" from the guix pull commit we are currently at.
The question of security updates is tricky at the moment already =E2=80=94 I
would hazard a guess that many people bail out of upgrading when they
can't get substitutes for their entire profile / system right now, which
means they are not getting security upgrades for package (a) when a
substitute for (b) fails.
Thanks for your thoughts =E2=80=94 super intriguing!

This is a great idea. Any kind of fetch policy could be implemented with this, including one that considers the contents of a manifest. This is another of these instances where having a general purpose programming language underpinning it all really pays off. -- Ricardo

This is a nice idea and it makes me remember that it would be useful to
provide a way to avoid installing something that is cricitally broken,
like Debian's apt-listbugs package/facility
(https://packages.debian.org/sid/apt-listbugs).

Fine, but I rarely care about all of Guix, or all of any other channel. I care about the small subset of packages that I actually use. Better yet, with a per-manifest/profile approach, I could put my most critical packages in a special profile and get updates for them more quickly, while still working only with substitutes. BTW, just out of curiosity: for how many commits in Guix history all packages could be built successfully? Is that the rule of the exception? > Yes, we could do that, and even maybe more sophisticated things (e.g., > looking at the commit log to determine whether security fixes are > available, and adjusting the strategy accordingly.)

I agree, it's nice to give people the tools they need to implement their own policy. Konrad.

Yes, we could do that, and even maybe more sophisticated things (e.g., looking at the commit log to determine whether security fixes are available, and adjusting the strategy accordingly.) What I find interesting is that we can provide the tools to support such policies, and then users can choose or implement the policy they want directly in ~/.config/guix/channels.scm. Ludo=E2=80=99.

I really like that idea, but it's a pity to limit it to channels.
Two scenarii I'd like to see covered are:
1) Find the latest commit with all substitutes required by a given
manifest.
2) Find the latest commit with all substitutes required for updating a
given profile.
This is in fact only one problem with two user interfaces.
Konrad.

Hi Alex,
(Cc=E2=80=99ing <https://bugs.gnu.org/32022> and <https://bugs.gnu.org/2660=

which are related.)
Alex Sassmannshausen <alex@HIDDEN> skribis:

I just had a bright idea (yes!): this can be addressed by writing
something like this in ~/.config/guix/channels.scm:
(map latest-commit-with-substitutes-available
%default-channels)
The hypothetical =E2=80=98latest-commit-with-substitutes-available=E2=80=99=
would use
(git) and (guix ci) to find the latest commit for which substitutes of
interest are available, and would return:
(channel
;; =E2=80=A6
(commit "cabbag3")) ;the ideal commit
This has to be done with great care to prevent a downgrade attack and to
make sure the user doesn=E2=80=99t miss out on security updates, but maybe =
we
could provide a procedure that makes reasonable choices.
Food for thought=E2=80=A6
Ludo=E2=80=99.

I'm not sure. Clients could check, among the packages that are to be installed, which ones are substitutable (with the =E2=80=98substitute-paths=E2=80=99 RPC or = similar) and filter out those that are not. No C++ involved. Cheers, Ludo=E2=80=99.
