ci: enhance cleanup-space action for release builds
In this commit, we significantly expand the cleanup-space GitHub Actions
workflow to free up substantially more disk space on GitHub runners. The
previous cleanup only removed three large toolsets (dotnet, android,
ghc), which should free ~14GB. This enhancement adds removal of several
additional large packages and caches, bringing the total freed space to
approximately 20-25GB.
The specific additions include removing Swift and Julia language runtimes,
the hosted toolcache directory, all Docker images, numerous large apt
packages (aspnetcore, llvm, php, mongodb, mysql, azure-cli, browsers, and
development tools), and various cache directories. We also add disk space
reporting before and after cleanup to provide visibility into how much
space is actually being freed during workflow runs.
This enhancement was motivated by release builds running out of disk space
when building for all 15 supported platforms (darwin, freebsd, linux,
netbsd, openbsd, windows across multiple architectures). The sequential
builds with verbose output were consuming more space than the basic cleanup
could provide.
What changed, and why it matters
This commit only changes a GitHub Actions workflow that deletes unused software from build machines to free up disk space. It is a routine infrastructure/maintenance change and does not modify any wallet, network, or cryptographic code. There is no security issue visible in the diff.
No security action required. Treat as normal CI maintenance.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The patch expands .github/actions/cleanup-space/action.yml to remove additional pre-installed toolchains, Docker images, apt packages, and caches from GitHub-hosted runners. The stated goal is to reclaim 20-25 GB of disk space so release builds for 15 cross-compilation targets do not run out of space. No application code, secrets, permissions, or network behavior are changed.
