wasmtime/27.0.0-r0: fix GHSA-h97m-ww89-6jmq

Advisory data: https://github.com/wolfi-dev/advisories/blob/main/wasmtime.advisories.yaml

Gen AI suggestions to solve the build error:

• Detected Error: The error output doesn't show a specific failure message, but appears to stop after package installation without completing the build

• Error Category: Build/Configuration

• Failure Point: Silent failure after dependency installation, likely during the "Configure and build" step

• Root Cause Analysis: For Rust projects of this size, common build failures occur due to insufficient system resources, particularly in CI environments

• Suggested Fix:

1. Add CARGO_NET_GIT_FETCH_WITH_CLI=true to environment section:

environment:
  contents:
    packages:
      - build-base
      - busybox
      # ... existing packages ...
  variables:
    CARGO_NET_GIT_FETCH_WITH_CLI: "true"
    RUST_BACKTRACE: "1"
    CARGO_TERM_VERBOSE: "true"

2. Add llvm-dev to the package dependencies:

    packages:
      - build-base
      - busybox
      - llvm-dev
      # ... existing packages ...

• Explanation:

• CARGO_NET_GIT_FETCH_WITH_CLI helps with git submodule handling
• RUST_BACKTRACE provides better error reporting
• llvm-dev is often required for wasmtime's LLVM dependencies
• Adding verbose cargo output helps diagnose build issues

• Additional Notes:

• Wasmtime is a complex project with many dependencies
• The build might benefit from explicitly setting RUSTFLAGS for optimizations
• Consider adding --jobs 2 to cargo build for CI resource constraints

Gen AI suggestions to solve the build error:

• Detected Error:

error: failed to select a version for the requirement `idna = "^0.3.0"`
candidate versions found which didn't match: 1.0.0
location searched: crates.io index
required by package `url v2.3.1`

• Error Category: Dependency/Version

• Failure Point: rust/cargobump step attempting to update the idna crate

• Root Cause Analysis: There's a version conflict between the specified idna 1.0.3 update and url 2.3.1's requirement for idna ^0.3.0. The versions are incompatible.

• Suggested Fix:

1. Modify the cargo update commands in the pipeline to update both packages in the correct order:

  - name: Configure and build
    runs: |
      git submodule update --init
      
      # mitigate GHSA-2qv5-7mw5-j3cg
      cargo update spin --precise 0.9.8
      
      # Update url first, then idna
      cargo update url --precise 2.4.1
      cargo update idna --precise 0.3.0

• Explanation:
The error occurs because url 2.3.1 specifically requires idna ^0.3.0, but we're trying to force idna 1.0.3. By updating url first to a newer compatible version (2.4.1) that supports newer idna versions, we can resolve the dependency conflict.

• Additional Notes:

• The crate versions need to be updated in a specific order to maintain compatibility
• If needed, you can verify compatible versions using cargo tree -i url or cargo tree -i idna
• Consider adding a comment documenting the dependency relationship
