This is incorrect when cross-compiling, use
(->bool (not (%current-target-system)) instead.

Or simpler:

(substitute-keyword-arguments
  (strip-keyword-arguments '(#:tests?) (package-arguments base-rust)))

Also, I'm wondering, should #:tests? #t be removed from 1.57?
From rust.scm:

       ;; Only the final Rust is tested, not the intermediate bootstrap
ones,
       ;; for performance and simplicity.
       #:tests? #f

[bug#54439] Rust: Add Rust 1.59, set default to 1.59.

[Paul Alesius]

Thank you for the input.

I was unable to build the latest version (1.59) without also building
the intermediate versions (1.58), hence why the package declarations
for 1.57 and 1.58 remained intact with testing as I was verifying that
they build.

You're right, the bootstrapping releases should be trimmed down. I am
very new to Guile so if anyone wants to modify the patch while I learn
the build system to create a new patch, that would be fine with me.

/With regards
- Paul

I'm wondering, does rust@1.59 need to be built against rust@1.58, or
could it be built against an earlier version rust@1.57?  I would prefer
the latter to avoid increasing the bootstrapping chain further.

Greetings,
Maxime.

I believe the conventional terminology is ‘this version’ or ‘this
release’, not ‘this distribution’.

Due to the large number of dependents this probably needs to be done on
core-updates (unverified)

Is this necessary?  This was not done in
<https://issues.guix.gnu.org/54475#0>.

Nope, (delete 'skip-shebang-tests) didn't seem necessary, it must have been
something with my environment before.

The patch in <https://issues.guix.gnu.org/54475#0> builds and tests for me
too, seemingly without testing the bootstrapping rustc.

[bug#54439]

[kiasoc5--- via Guix-patches via]

Is it safe to update mrustc at the same time as the rust version bump? So we can bootstrap from rust 1.54 to 1.59. Sorry, I don't have the time and hardware to help out more.

Hi there,

Updating mrustc would be great, as an added bonus, the latest version
enables aarch64-linux support.  I just submitted a patch for it [0], it
would be great to pick it up when next updating rust.

[0]: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=54580

I did also play with boostrapping directly from 1.54, instead of just
updating mrustc, but it's not building for me yet.  I'm attaching my WIP
patch in case somebody wants to take a look.  Specifically, it's failing
during the cargo build phase, so when testing it I recommend to run the
cargo build first to reproduce the issue.  I can post a log later, I
don't seem to find it just now :-).

If you'd opened or contributed to this issue, would you be motivated by 
such replies?  I wouldn't...

There must be a more effective way to help move things forward.

Regardless, Rust release announcements don't need to be cross-posted to 
the Guix bug trackers and all bug-guix@ subscribers.

Kind regards,

I'm sorry, I won't cross-post future updates. I can try the bump
myself, it's just that I feel like this is too much of a challenge for
me.

I updated Rust to 1.57 when I was new to Guix, it wasn't very hard at
all. The main problem was that the build took aaaaaaages. See commit
89afe76a164c53aef66e6f819137bd0c65089fe8.

I got 1.60 to build by using LLVM 14. Rust 1.61 fails to build, one of
the tests hangs for many hours.

[bug#54439] [PATCH core-updates] gnu: rust: Use rust-1.60.0

[Jim Newsome]

Hi, I'm new to this project and this code-review workflow, so please bear with me :).

It looks like there have been a few attempts here at updating Rust, including [Paul's], [Felipe's], and [my own].

[Paul's]: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=54439#5
[Felipe's]: https://issues.guix.gnu.org/54475#0
[my own]: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=56684

There's some discussion in this thread about using an updated mrustc and using that to cut out some earlier steps of the bootstrap chain. I propose leaving that out for the moment. It seems both nontrivial and orthogonal, so IMO would make more sense as its own thread / patch-set, which could be reviewed and merged independently, before or after this one.

I think there's some confusion about where and how tests are enabled/disabled. IIUC in the current baseline, they are disabled in `rust-1.55`, which is the first version built with an earlier "official" rust:

```
       ;; Only the final Rust is tested, not the intermediate bootstrap ones,
       ;; for performance and simplicity.
       #:tests? #f
```

and subsequent versions inherit that via the `rust-bootstrapped-package` function.

The latest and public version (currently `rust-1.57`) re-enables most of the tests and fixes up some things so that the tests pass.

So I think the approach here when adding versions is to change the current latest (1.57) to the simpler form that keeps tests disabled, add any additional necessary steps, and have the test-reenabling code again in the latest version.

2 patches included:

* First is a pure refactor to decouple  "rust-1.57" from "rust" to help avoid confusion in the future.
* Second adds 1.58, 1.59, and 1.60, and makes rust-1.60 the new rust.

In the latter patch I also tried building each version with a Rust 2 versions back instead of just 1 version back, to see if any can be left out. Unfortunately they couldn't. I'm including some of the errors in the comments for reference.

Indeed.  :-/

This has recently been done on the 'staging' branch courtesy of Efraim.

That is my understanding too.

LGTM, I've pushed both patches to the 'staging' branch since Rust was
already patched there and it has not started evaluating yet.

Note: I also added a copyright line for you, hope that was okay.

Closing the issue, but feel free to continue the discussion.

Great! Thanks, and let me know if any additional follow-up is needed!

[bug#54439] [PATCH core-updates 1/2] gnu: rust: decouple rust-1.57 and "rust"

[Jim Newsome]

From: Jim Newsome <jnewsome@torproject.org>

* gnu/packages/rust.scm (rust-1.57, rust): decouple the definition of
rust-1.57, which happens to be the current latest, from the definition
of rust, which is always the latest. The latter re-enables tests and
extra components, which should always be done only on the final public
rust package, not specifically rust-1.57.
