Antoyo's Personal Blog

I’ve been pretty busy in my life recently, but I finally got around writing this blog post. Hopefully, things are sorted out in my personal life and I should be able to be more regular about these updates in the future.

I’m very happy to see good progress towards rustup distribution (thanks to Kobzol again!).

    Oh, and clean all doesn’t work reliably. Since trying to build in release mode after building in debug mode then cleaning is weirdly broken.

    And It’s not clear from the README how to build in release mode without running test --release. And the fact that all combinations of --release-sysroot and --release --sysroot and --release --release-sysroot exist doesn’t help 😉

      Thanks for reporting this! I cannot reproduce with the following:

      y prepare
y build --release
y build
y clean all

      (it shows: Successfully ran clean all)

      Could you please provide the commands you ran to get this? (It might also be easier for me to track this if you open an issue on GitHub since I don’t come here often.)

      Also, thanks for the suggestion for better documentation: I created an issue for this.

        Yeah, apologies for not communicating the issue clearly.

        cp config.example.toml config.toml
./y.sh prepare
./y.sh build --sysroot
./y.sh clean all
# above commands finish with success
# below, building succeeds, but it later fails with "error: failed to load source for dependency `rustc-std-workspace-alloc`
./y.sh test --release

        And then trying to use the “release” build fails:

        % CHANNEL="release"  ./y.sh cargo build  --manifest-path tests/hello-world/Cargo.toml

        I will make sure to report issues directly in the future, although from account(s) not connected to this username.

          The issue here is that you didn’t provide --build-sysroot to ./y.sh test --release, so it cannot find the std crate.

            But running

            ./y.sh prepare
./y.sh test --release

            does work. That’s what gave me the impression that clean all doesn’t actually clean everything!

              It does actually clean everything. You need to call ./y.sh prepare again if you ran clean all; otherwise, it will fail to find some stuff like rustc-std-workspace-alloc.

              I opened an issue to improve the documentation in this regards. Thanks for testing all this: this will help me improve the documentation.

                You need to call ./y.sh prepare again

                Aha! Good to know. And yes, improved documents would be of great help.

                Thanks again for working on this.
