Self-host tarballs on asger.weirsoe.dk instead of GitHub Releases
Serve from /srv/tarballz on CT148 via a 'location /tarballz/' alias, NOT from under /var/www/asger: the asger-web deploy swaps that whole directory atomically, so tarballs kept inside it would be deleted on the next site deploy. CT148's rootfs was 3G with 2.7G free - one tarball would have filled it - so it is grown to 15G; speedy's thin pool has room even though vgs reports the VG nearly full. Publishing uploads to a .part name and renames on arrival so a download can never see a truncated file, verifies sha256 on the host, then fetches the public URL and checks it against the sha256 baked into the PKGBUILD. Both checks run before the AUR push, so the package cannot go out pointing at a missing file. Old tarballs are pruned to the newest three. GH_TOKEN is kept but demoted to an optional GITHUB_PAT for R module downloads; it no longer has anything to do with publishing.

The GitHub repo `GH_OWNER/GH_REPO` must exist and be public — the AUR PKGBUILD
|
||||
downloads the tarball from its releases, so it has to be reachable anonymously.
|
||||
### Where the tarballs live
|
||||
|
||||
Tarballs are served from `https://asger.weirsoe.dk/tarballz/`, backed by
|
||||
`/srv/tarballz` on CT148.
|
||||
|
||||
They are **not** stored under `/var/www/asger`. The `asger-web` deploy replaces
|
||||
that entire directory atomically — it unpacks into `.new`, swaps it in and
|
||||
deletes the old one — so anything kept inside it would vanish on the next site
|
||||
deploy. nginx exposes `/srv/tarballz` through a `location /tarballz/` alias
|
||||
instead, with `gzip off` so makepkg gets a plain byte stream.
|
||||
|
||||
Note that `asger.weirsoe.dk` 301-redirects to the IDN form
|
||||
`asger.xn--weirse-fya.dk`. makepkg follows redirects, so the readable hostname is
|
||||
used in the PKGBUILD, but that redirect is load-bearing — if it is ever removed,
|
||||
the `source=` URL must be repointed.
|
||||
|
||||
The publish step verifies the uploaded copy's sha256 on the host, and a separate
|
||||
step then fetches the *public* URL and checks it against the sha256 baked into
|
||||
the PKGBUILD. Both run before the AUR push, so the package can never be published
|
||||
pointing at a missing or truncated file.
