Hi,
the packaged restic is at 0.9.6 while upstream is at 0.15.1. I thought
I'd try to update the package to learn how to package things for guix.
I'm a complete noob with that, and I have zero experience with go.
I'm using guix system in qemu with
qemu-system-x86_64 -drive media=disk,file=geex-unenc.img,format=raw
-bios /usr/share/ovmf/x64/OVMF.fd -m 2G -smp 3 -nic
user,model=virtio-net-pci,hostfwd=tcp::2223-:22 -enable-kvm
I used guix edit restic as a starting point and saved it in
~/packages/restic.scm. I removed all other programs, renamed restic to
restic-new, adjusted the hash, removed a patch for an older go, and used
a newer go version for the build system, as 1.17 is too old for restic 0.15.
Now the build fails trying to download dependencies:
$ guix build -L packages/ -K --fallback restic-new
...

Looks like go trys using ipv6 for the dns lookup. But
/etc/resolv.conf says
nameserver 10.0.2.3
I don't have a nameserver running on ::1. And this inside qemu, where I
didn't set up anything specifically for ipv6. I have only site and link
local ipv6 addresses. Why does go-build-system try to resolve the host
names at [::1]:53?

(synopsis "Backup program with multiple revisions, encryption and more")
(description "Restic is a program that does backups right and was designed
with the following principles in mind:
@itemize
@item Easy: Doing backups should be a frictionless process, otherwise you
might be tempted to skip it. Restic should be easy to configure and use, so
that, in the event of a data loss, you can just restore it. Likewise,
restoring data should not be complicated.
@item Fast: Backing up your data with restic should only be limited by your
network or hard disk bandwidth so that you can backup your files every day.
Nobody does backups if it takes too much time. Restoring backups should only
transfer data that is needed for the files that are to be restored, so that
this process is also fast.
@item Verifiable: Much more important than backup is restore, so restic
enables you to easily verify that all data can be restored. @item Secure:
Restic uses cryptography to guarantee confidentiality and integrity of your
data. The location the backup data is stored is assumed not to be a trusted
environment (e.g. a shared space where others like system administrators are
able to access your backups). Restic is built to secure your data against
such attackers.
@item Efficient: With the growth of data, additional snapshots should only
take the storage of the actual increment. Even more, duplicate data should be
de-duplicated before it is actually written to the storage back end to save
precious backup space.
@end itemize")

Ok, naturally, we don't want go to access the internet to get the
dependencies.
I tried adding (inputs (list go-github-com-minio-sha256-simd))
to the package, but go still tries to get that. Go doesn't care about
the symlinked package at src/github.com/minio/sha256-simd.
(Someone added that symlinking to go-build-system once, so it may have
worked with earlier (<1.18) go versions?
https://issues.guix.gnu.org/50493 references
https://issues.guix.gnu.org/50227 , which I don't understand, but seems
to try to get rid of the symlinking and replace it with something better?)
If I run go run build.go manually in the failed dir, the dependencies
get downloaded to
[...]
/pkg/mod/cache/download/google.golang.org/genproto
/pkg/mod/cache/download/google.golang.org/grpc
/pkg/mod/cache/download/google.golang.org/protobuf
/pkg/mod/cache/download/go.opencensus.io
/pkg/mod/cache/download/gopkg.in/
/pkg/mod/cloud.google.com
/pkg/mod/github.com
/pkg/mod/golang.org
/pkg/mod/google.golang.org
/pkg/mod/go.opencensus.io@v0.24.0
/pkg/mod/gopkg.in
etc.
and not to /src/github.com/ or such, where inputs get symlinked at.
My conclusion: go-build-system needs to be updated to account for the
new way go handles dependencies.
Is this correct? And is this issue 50227?
