My first release, a help request

[stappersg]

I'm new to the workflow of a release, I'm asking for help.

Goal is the actual switch from llvm_asm! to asm!.

actual switch and version bump have been done.

The failed CI run for Fix build: Use the new rust asm! available in rustc 1.63.0-nightly indicates something extra needs to be done. Maybe something like adding a git tag or sending some trigger signal.

What should I do next?

[stappersg]

FYI

$ git push --tags
Total 0 (delta 0), reused 0 (delta 0), pack-reused 0
To github.com:avr-rust/delay.git
 * [new tag]         0.4.0 -> 0.4.0
$

The build bot says

error[E0472]: asm! is unsupported on this target

Is it using an older version of rustc? Only the very latest rust nightly has fixed AVR8 support plus all new features like asm! macro.

[mbuesch]

Step 6/11 : RUN wget -q https://sh.rustup.rs/ -O /tmp/rustup.sh && sh /tmp/rustup.sh -y --profile minimal --default-toolchain nightly-2021-01-05 -c rust-src --quiet

That's too old.

That was the last release before they broke AVR8 support. But it has been fixed now, so an upgrade of the compiler can (should) be done.

[stappersg]

Yes, we could also be bitten by an old version. We will deal with it in another issue.

For releasing avr_delay I report:

$ cargo publish
    Updating crates.io index
error: no upload token found, please run `cargo login` or pass `--token`
$

AFAIK I have no cargo credentials, I will persuit them.

Those who are more comfortable with cargo publish:
Are cargo logins and crates coupled?
Incase of yes, they are: How to add an account to a crate?

[mbuesch]

The owner of a crate can add other owners to the crate in the crate's settings on crates.io (github login).

Ah, thanks @mbuesch and high-lighting @dylanmckay for further awareness on the pending request.

One common option here, especially since you're already using GitHub Actions for CI, would be to also leverage it to publish to crates.io upon pushing a new tag. You'd need to set up an API token as a shared secret (which can be either specific to this repo, or to the avr-rust org as a whole).

Something like this might work:

on:
  push:
    tags:
      - '*'
  name: Publish to Cargo
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions-rs/toolchain@v1
        with:
          toolchain: nightly
          profile: minimal
          override: true
          components: rust-src
      - uses: actions-rs/cargo@v1
        with:
          command: publish
          args: --token {{ "${{ secrets.CARGO_API_KEY " }}}}

If you're interested, I'd be happy to work on PRs to this effect, both for this repo as well as https://github.com/avr-rust/ruduino/

@dylanmckay -- you're listed as the owner of https://crates.io/crates/avr_delay

Would it be possible for you to either provide @stappersg a crates.io API token for this project, or create one as a GitHub repository secret (which means it would be usable but not viewable by the other delay repo owners) so we can get the crates.io version updated from 0.3.2 -> 0.4?

This update is important because it includes the transition from llvm_asm -> asm macro, which allows compilation on a current nightly rust toolchain; this is a blocking issue for making the avr-rust/blink extremely easy for end users to build -- I think making that hello, world to Rust on AVR as easy as possible will open some doors for beginners!
