Fwd: [GNU bug Tracking System] bug#73864: Acknowledgement ([PATCH] gnu: rust: update to 1.82)

Note that we already have Rust 1.81 in rust-team, and I have already
sent a patch to update to 1.82 (the latest stable). Usually Efraim
reviews these updates.

By the way, if you want to use Rust 1.82.0 before it gets accepted for
the default guix channel, you can use my channel (and install
`rust-next`, `rust-next:cargo`, and `rust-next:tools`):

Is there any plan to add rustup to the package as well? This is useful for adding targets for cross-compilation.

Cheers,
Marco

I don't have plans to add that in my channel (I don't use it), but if
someone packages it and gets it to work, I'd be happy to take a PR.

I doubt it will ever land in the main Guix channel since distributing
software whose sole purpose is to download and install software in
binary form seems to me to be contrary to the Guix philosophy. That
said, there is no good reason someone couldn't package it and include it
in another channel.

Hello Brennan,

That sounds like good news then. It should be available in the guix channel soon then?

I'm not sure I have the time to do all the testing necessary for bumping
rust to 1.82 currently so right now I'm about to join the merge queue
with rust-1.81.

It will be available after (1) it is reviewed and merged to the
rust-team branch, and (2) the next time after that when rust-team is
merged to master.

I can't predict how long that will take, but it could be a few
months. If you urgently need Rust 1.82 faster than that, you need to
take another approach, for example, one of the following:

* Configure your system to use the rust-team branch rather than master,

* Use my guix-rust-next channel I linked in the other thread (note: not
  supported by the official Guix project, but it's working for me),

* If you're on a foreign distro, just install Rustup and don't use Guix
  for Rust stuff. (Less feasible if you're on GuixSD).

In general, Guix is not a distribution where major changes to packages
land immediately, so in cases like Rust where the language is
fast-moving enough that most developers want to use the latest version,
you have to get used to using some workaround.

Efraim, let me know if/how I can help with testing/maintaining new Rust
releases. I've been sending the patches for new versions as they come
out but I'd also be able to help in other ways if you tell me more about
what your workflow is for merging them.

Currently I first build the new version on the 3 supported architectures
for rust, x86_64, aarch64 and riscv64. I also try building the non-rust
package version, since we'll be using that one to build a future version
of rust.

After the rust package itself builds I normally try building something
simple like zoxide on each architecture, and I'll try cross-compiling it
too (only from x86_64) to test that the rust sysroot package doesn't
need changes. From there I can be pretty sure everything should be good
and I attempt to build the list of cargo-build packages which don't
start with "rust-" and fix those or their dependencies as needed. Then
I'll try building all the rust packages and fix those I can.

In terms of testing, for recent versions it's really only been a failed
test here or there for aarch64 and riscv64, so if the zoxide and cross
zoxide both build then that's pretty much everything.

Interesting tidbits:
In terms of cross building, on some versions the windows versions work
and on some they don't, they generally don't like that we strip out the
bundled libraries. The Hurd may or may not work, and a number of crates
still need some logic touch-ups to deal with it. 32-bit powerpc has some
quirks in rust that prevent some crates from working, but also makes a
good cross-target since it's such a niche target, being incredibly old
and big-endian. And I can actually test binaries built if necessary.

How are you building for riscv64 ? Do you have access to an actual
risc64 machine or are you using an emulator? Or do you cross-compile
from x86 or arm?

I've always been jealous of people who have access to exotic hardware so
I've actually picked up a bunch of other machines over the years. I
currently have 3 riscv64 boards which build reasonably quickly and a
number of aarch64 boards, not all of which I actually have in use. I do
occasionally use the qemu-binfmt-service on my x86_64 machine to speed
up builds, but generally for things like deblobbing the kernel or if a
build takes more RAM or storage than I can handle on one of the
machines.

I realize I didn't mention it, but if zoxide and cross zoxide work from
x86_64 specifically then generally everything should be fine and I can
run the other architectures through a couple of times to update the
skipped tests there, if there are any.
