v1.4.8

Package mirrors: probe first, then trust

On 2026-08-30 the NetBSD.org package hosts went down together -- cdn.NetBSD.org and ftp.NetBSD.org are the same infrastructure behind a CDN, not independent mirrors -- and every pkg_add in every job spent minutes per package in TLS timeouts before dying.

The VM now probes the package mirrors at startup and points pkg_add at the ones that actually answer: cdn.NetBSD.org, ftp.NetBSD.org, the official French mirror ftp.fr.NetBSD.org, ftp.jaist.ac.jp and ftp.allbsd.org, in that order, keeping only the live ones. Dead hosts are dropped entirely rather than kept as fallbacks, because pkg_add walks the whole list for every package it installs, and each dead https entry costs minutes per package. If nothing answers, the configuration is left untouched.

This also retires a long-standing trap in the image's default configuration: its PKG_PATH ended with a NetBSD 9.0 fallback, so a package missing from the preferred hosts was silently installed from the 9.0 set, linked against libraries the running release does not ship. All entries are now same-release only.

The probe runs on every VM start, including boots from a cache-after-prepare image, so the mirror list is always from the current run, never frozen into a cache. Verified during the outage itself: with both NetBSD.org hosts dead, prepare installed its packages from the French mirror on the first try.

Under the hood

The runtime moves to anyvm v0.6.6. Changes under hooks/ now retrigger the project generation, so a hook fix is picked up by the test matrix without waiting for the daily rebuild.

v1.4.7

sync: tar

A new way to share the workspace: the tree is streamed in as a ustar archive over the ssh connection the action already opens, and streamed back the same way when the run finishes. Nothing is installed in the guest and no filesystem support is needed on either side, unlike sshfs
