📝 Walkthrough

Walkthrough

The release workflow now builds Linux artifacts in target Ubuntu containers across multiple releases and architectures. A Docker build script prepares dependencies and handles older GCC versions. Build metadata records the target Ubuntu release, and release staging uses absolute workspace paths.

Changes

Cross-distribution release builds

Layer / File(s)	Summary
Target-aware build metadata mk/make.py	DANDELION_TARGET now adds the Ubuntu target to platform metadata and version.txt.
Container build environment and compiler fallback .github/scripts/docker-build.sh	The script configures Ubuntu repositories, installs the build environment, runs Nuitka, retries older GCC builds with GCC 9, and restores host ownership.
Matrix builds, smoke tests, and release staging .github/workflows/release.yml	The workflow adds Docker Linux builds for Ubuntu 18.04–26.04 and both architectures, uses target-specific caches and artifact names, runs container smoke tests, and stages release zips under GITHUB_WORKSPACE.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to d5e5b

The release workflow currently executes version-derived text as shell code and runs an unpinned remote installer with root privileges, creating a concrete risk of unauthorized command execution or tampered release artifacts. The PR is not merge-ready until these issues are fixed.

In @.github/scripts/docker-build.sh:
- Around line 38-39: Replace the unpinned installer pipeline in the uv
installation step with a download of the required pinned glibc/musl uv release,
verify the downloaded file against its official SHA-256 checksum, and execute it
only after verification; preserve the existing installation behavior without
piping remote content directly to sh.

In @.github/workflows/release.yml:
- Line 241: Update the release workflow steps around the Docker invocation and
archive-name assignment to expose the computed tag through each step’s env block
as RELEASE_TAG, rather than interpolating the tag directly into Bash source.
Pass the variable to Docker via DANDELION_VERSION="$RELEASE_TAG" and use
"$RELEASE_TAG" when constructing release archive names.
