builder-web/CHANGES.md

v0.2.0 (2024-09-05)

A whole slew of changes. Internally, we made a lot of incremental changes and improvements without doing a release. Thus this release is rather big. There is a lot of database migrations to apply, and unfortunately they have to be applied one at a time.

• Add a /failed-builds/ endpoint that lists the most recent failed builds.
• By default don't display failed builds on the front page.
• Times are printed with the 'Z' time zone offset indicator.
• Link to comparisons of builds take into account whether the "input", among others the list of dependencies, is different.
• New subcommand builder-db extract-build takes a build UUID and extracts the builder "full" file.
• Add /job//build//all.tar.gz endpoint with a gzip compressed tar archive of all build artifacts.
• Visual overhaul.
• Add (optional) visualizations displaying package dependencies ("opam-graph") and for unikernels a "modulectomy" view of how much each OCaml module is contributing to the final binary size. The visualizations are read from a cache on disk and can be generated from a script.
• A script hook is added on file upload. It may be used to generate visualizations or publish system packages to a repository.
• The 404 file not found page tries to be more informative.
• The build page for a unikernel build displays the solo5 device manifest, e.g. with block devices "storage", and net devices "service".
• URLs with trailing slash redirect to without the trailing slash.
• Builder-web will try to be more helpful if its database doesn't exist or the database version is wrong.
• The opam diff works for mirage 4 unikernels taking into account the opam-monorepo/duniverse packages.
• Markdown rendering is now done using cmarkit instead of omd.
• Builder-web doesn't display jobs older than 30 days (customizable with --expired-jobs command line argument) on the front page.
• Build artifacts are stored by their content, and artifacts are automatically deduplicated. This makes builder-web much more space efficient on deployments that don't use deduplication on the filesystem level.
• New subcommands builder-db vacuum * to remove older builds. Can be called from a cron job to keep disk usage bounded.
• Lots of other improvements and bug fixes.
