Description Rémi Verschelde 2017-07-29 17:53:32 CEST

Why we update rust and cargo:
=============================

The rustc compiler (rust package) and cargo package manager are the two main components of the Rust programming language, and get new versions every 6 weeks from Mozilla.

As nothing depends on rust yet in Mageia 6, and the language is still young and constantly evolving, we propose to keep track with the upstream releases also in Mageia's stable branch, which means we'll have one such update every 6 weeks. This is important for any rust user in Mageia 6, as they need the latest stable toolchain for their own development work.

The next ESR version of Firefox might also require rust, so we need to keep the packaging up to date.


Advisory:
=========

Updated rust and cargo packages bring latest stable release

  This update provides Rust 1.19.0 and Cargo 0.20.0, which are the current
  stable versions released on July 20, 2017. See the release announcements
  for more details.

A simple way to test would be helpful then Rémi.

Well, I was writing the testing procedure as you posted this ;)

Testing procedure:
==================

As of now there are no packages depending on rust in Mageia 6, apart from rust and cargo themselves, so only those two need to be tested.

The cargo package manager allows to download "crates" (source code for rust libraries and applications) and compile them automatically for you, so it's a very simple way to test the toolchain. You can try installing any crate with `cargo install <crate name>`.

Here are some crates you can test:
- ripgrep: a very powerful search tool similar to grep or ack (but better :))
- iota-editor: a simple console text editor

Some crates may fail building if they're not compatible with the current rust version, but that's ok - we're not testing them, only testing that the compiler and dependency managers themselves work.

Excellent :)

Comment 6 Rémi Verschelde 2017-07-30 10:56:59 CEST

Advisory uploaded, validating as it's not a critical component for now so it doesn't need very thorough testing.
