Hi everyone,
We've staged a beta release of Rustup 1.24.3 which resolves a few more regressions in low-tier systems.
In particular, there was a report that on FreeBSD the install would hang. We've fixed that (we hope) in this release.
If you want to use this in your CI to test, then you need to set RUSTUP_UPDATE_ROOT=https://dev-static.rust-lang.org/rustup before you install, and for the duration of any rustup operations which might download toolchain components.
You can try updating your local copy by setting that environment variable and running rustup self update though you should be aware that any subsequent update without the environment variable will revert you to 1.24.2 (current released Rustup).
One new feature in 1.24.3 though is the ability to set rustup set auto-self-update disable which will prevent that behaviour. You can then set it to enable when you're done beta-testing and run rustup self update to revert to the release.
Changelog snippet for this release:
1.24.3 - 2021-05-31
This patch release focusses around resolving some regressions in behaviour in the 1.24.x series. One problem, related to accounting for the release of data blocks in the unpack slab allocator, fixed in pr#2779, would manifest in the installer hanging during installation. A second, fixed in pr#2781, manifested in very early Rust versions (1.0 through 1.7) repeatedly having their checksums fetched despite already being installed. Finally the heuristic which started warning that toolchains being installed may not work on the given host was improved in pr#2782 to reduce false-positive rate and reduce worry among Windows users in particular.
Added
- Added the ability to configure the auto-self-update functionality. This will
be of most use when people are testing unreleased versions of Rustup and wish
to ensure they don't accidentally lose the test version, without having to
remember to run with
--no-self-updateall the time. pr#2763
Changed
- We no longer delete the top level of
$RUSTUP_HOME/tmpand$RUSTUP_HOME/downloadmeaning that if you have these set up as symlinks to another place, or bind mounts, etc. things should work. pr#2433 - We more gracefully handle outlier situations with unpack-RAM, panicing less often, clamping settings into viable ranges and warning instead. pr#2780

Anyone who wants to test any of the above would be appreciated. Ditto some checks that we've not re-broken any other platforms would be good. The regressions in this release were regrettably hard for us to spot beforehand. Beta-testing is critical to trying to find and prevent them in future.
