Alex Crichton b553d84362 Change how security advisories work on CI (#3461) 
Before this commit we actually have two builders checking for security
advisories on CI, one is `cargo audit` and one is `cargo deny`. The
`cargo deny` builder is slightly different in that it checks a few other
things about our dependency tree such as licenses, duplicates, etc. This
commit removes the advisory check from `cargo deny` on CI and then moves
the `cargo audit` check to a separate workflow.

The `cargo audit` check will now run nightly and will open an issue on
the Wasmtime repository when an advisory is found. This should help make
it such that our CI is never broken by the publication of an advisory
but we're still promptly notified whenever an advisory is made. I've
updated the release process notes to indicate that the open issues
should be double-checked to ensure that there are no open advisories
that we need to take care of.

Release Process

This is intended to serve as documentation for Wasmtime's release process. It's largely an internal checklist for those of us performing a Wasmtime release, but others might be curious in this as well!

To kick off the release process someone decides to do a release. Currently there's not a schedule for releases or something similar. Once the decision is made (there's also not really a body governing these decisions, it's more whimsical currently, or on request from others) then the following steps need to be executed to make the release:

  1. Double-check that there are no open rustsec advisory issues on the Wasmtime repository.
  2. git pull - make sure you've got the latest changes
  3. Run rustc scripts/publish.rs
  4. Run ./publish bump
  • Review and commit the changes
  • Note that this bumps all cranelift/wasmtime versions as a major version bump at this time. See the bump_version function in publish.rs to tweak this.
  1. Make sure RELEASES.md is up-to-date, and fill it out if it doesn't have an entry yet for the current release.
  2. Send this version update as a PR to the wasmtime repository, wait for a merge
  3. After merging, tag the merge as vA.B.C
  4. Push the tag to the repository
  • This will trigger the release CI which will create all release artifacts and publish them to GitHub releases.
  1. Run ./publish publish
  • This will fail on some crates, but that's expected.
  • Keep running this script until all crates are published. Note that crates.io won't let you publish something twice so rerunning is only for crates which need the index to be udpated and if it hasn't yet. It's recommended to wait a bit between runs of the script.

And that's it, then you've done a Wasmtime release.
