I think it would probably make most sense for dpkg (which doesn't know about specific build systems) to not archive anything by default, or to archive only things it produced itself. For debhelper it might make sense for build system classes to archive well-known logs like Autotools' ${builddir}/config.log and Meson's ${builddir}/meson-logs/ by default, but probably not logs that are in an unpredictable location like Autotools' test logs. If there's an exclusion mechanism for packages that know a particular artifact is not useful and monstrously large ("!meson-logs/big.log"?) then it doesn't necessarily matter much either way. If artifacts aren't kept forever then the damage from archiving too much will be temporary. > The former makes it simpler for people that are interested in the > "default" parts but also bloats the archive for people that are > interested in just one file. Have you seen the UI Gitlab-CI and Jenkins provide for this? If you look at a Gitlab-CI job like <https://gitlab.gnome.org/GNOME/glib/-/jobs/624888>, there's a Download link that gives you the complete bundle of artifacts in a zip file, but there's also a Browse link like <https://gitlab.gnome.org/GNOME/glib/-/jobs/624888/artifacts/browse> that lets you look at individual logs online (which is often enough to debug an issue). Jenkins has a similar system. On Salsa, ci.debian.net (for tests with the needs-build restriction), and similar systems, I think it would make most sense to drop the artifacts into somewhere the "larger" CI system will pick them up, and let the "larger" CI system handle browsing and expiry. On buildd.debian.org, I think build logs are kept forever(?) but artifacts should probably have some sort of expiration mechanism, similar to the way ci.debian.net remembers test results indefinitely but discards old logs after a while. smcv
