Provenance tracking, yes. I wrote about the current status: (guix
describe), (guix channels), etc. expect a full Git repo, which is why
things are done this way.
We could imagine a different design, but that=E2=80=99s a broader endeavor.

The authentication mechanism is designed to make this impossible.
That=E2=80=99s why one can run:
guix pull --url=3Dhttps://github.com/guix-mirror/guix
without fear (worst that can happen is that the mirror is stale).

Do we care about provenance tracking for this scenario? Similarly, do we care about downgrade detection for this scenario? I mean, we are not talking about a regular scenario but as you said a worst-case scenario. Somehow, I am missing where =E2=80=9Csecurity=E2=80=9D (provenance tracking= and downgrade detection) fits in the picture. If tomorrow Savannah is totally down and let assume the malicious Eve is serving https://git.savannah.gnu.org/git/guix.git. The authentication is useless since Eve can easily rewrite it. The only mechanism that protects Alice is the commit SHA-1 hash she has at hand. Eve needs to attack this SHA-1 with some collision. And if it=E2=80=99s possible to pro= duce pre-image attack for SHA-1, then nothing would prevent Eve to also replace the origins of some packages in https://git.savannah.gnu.org/git/guix.git. Moreover, cloning from SWH using git-bare is not protecting neither. Well, you are trusting SWH. Somehow, you have no mean to be sure that the repository you get back from SWH is the one you expect. The only way is to inspect the signatures; it means the end-user knows exactly which gpg key from .guix-authorizations they must trust. Obviously, the former could be injected in the latter. ;-) Noting that SWH heavily relies on SHA-1, IIUC. Yeah, we should talk with SWH=E2=80=99s folks. :-) Cheers, simon

Being rare will not make it practical. ;-)
What I am trying to point is that considering the size of the Guix
repository and its rate, the current implementation will not scale and
the fallback will be impossible for the end-user.

Well, I do not see which features will be missing. I am talking about
making practical:
guix time-machine -C channels.scm -- shell -m manifest.scm
and not having a complete working Guix. Well, I read a paper that
mentions this command line, I want to inspect so I am running this
command. Somehow, I do not care about the others 114456 commits of
the history. And for sure "guix time-machine -C channels.scm --
describe -f channels" will not be a fixed-point.
Maybe, we could imagine an option for shortcutting the complete clone
and restrict to one specific commit.
Cheers,
simon

Even if the bug on SWH would be fixed, at the rate the Guix repo is
growing, it would be impractical to cook the whole Guix repo. And it
appears to me weird when we, most of the time, need a very restricted
set of commits.
We could imagine to locally create a new repo (git init) and only add
the content of the commit specified by =E2=80=9Cguix time-machine=E2=80=9D.
Cheers,
simon
PS: Just some numbers backing the rate of growing:
$ git log --oneline | wc -l
114457
$ git log --oneline --before=3D2019-05-01 | wc -l
43845
$ git log --oneline --after=3D2019-05-01 | wc -l
70612
1. We are cooking 43845 commits of the history that are useless because
unreachable with the time-machine. They pre-date the introduction
of the inferiors =E2=80=93 yes, we could refine and consider v0.15 inst=
ead
of v1.0.0. :-)
2. The first commit is from 2012. Over the first 7 years, 38% of the
history had been produced. In less than 4 years, we have produced
62% of the history! Yeah, that=E2=80=99s cool!
Basically, from now to less than 5 years, we will generate the same
number of commits as over the past 10 years.

Yeah, =E2=80=98clone-from-swh=E2=80=99 is really cloning, so it needs =E2= =80=98git-bare=E2=80=99. Generally, in the case of channels, we need a full clone, not just a revision. Various bits of the machinery expect the clone: (guix describe), (guix channels), and so on. Ludo=E2=80=99.

The server keeps closing the connection prematurely. Unlike our client
in Guile, wget keeps retrying and so, little by little, it eventually
gets more bytes. In my case it seems to get stuck at 90% though, where
each attempt gives it zero or very few additional bytes.
I suspect this is an issue at SWH. I=E2=80=99ll bring it up there.
Thanks,
Ludo=E2=80=99.

Hi,
Cool you did this test! :-)

Last time I checked that, I never got the object from SWH because a bug
on their side. Nice now they cook the content.
Note that SWH is an archive and so it is expected to take a long time to
extract a large dataset as the files of the Guix repository is. Many
data are stored cold not to say frozen and that=E2=80=99s why it takes a lo=
ng
time to warm them up.

Well, if I understand correctly, SWH cooked the full Git repository of
Guix and somehow it is probably too big. Hum, I do not know how to
investigate=E2=80=A6
Thanks for the report!

Hi Guix!
I was trying to use guix time-machine as I did in the past, but the
recent updates with software heritage seem to have broken my use of it.
Here's the channels.scm file I used:
