Skip AUR for now — attach the built Arch package to the GitHub release
Publishing to the AUR needs a maintainer AUR account and its SSH key registered as a secret here, neither of which exists yet. Rather than leave the workflow permanently failing at that last step, it now stops short of AUR and instead uploads the built .pkg.tar.zst to the same GitHub release it built from, as a plain downloadable asset (`pacman -U` to install). The AUR-push step is still in this file's git history if that setup happens later. Renamed publish-aur-package.yml -> publish-arch-package.yml to match. The render/validate steps are unchanged; new here is capturing the exact built package filename from inside the build container (makepkg is the only thing that actually knows it) and an upload step that follows the same create-or-reuse-release, strip-upload_url, POST-octet-stream pattern build-app.yml and backfill-releases.yml already use for GitHub assets, plus a delete-existing-asset-first step so a re-dispatch for an already-packaged version replaces rather than 422s. Verified with a real Docker run end to end: rendered a real PKGBUILD, built a real (synthetic) .deb through makepkg + namcap in an archlinux container, confirmed the container exits 0, and confirmed the exact package filename it captures (triple-c-bin-<version>-1-x86_64.pkg.tar.zst) round-trips out via docker cp intact.

# Builds the `triple-c-bin` Arch package (packaging/arch/PKGBUILD) for a
|
||||
# given release, or the latest one if none is given, and attaches the built
|
||||
# .pkg.tar.zst to that release on GitHub as a downloadable asset. Manual
|
||||
# dispatch only — deliberately not triggered by `release` or `push`, for the
|
||||
# same reason sync-release.yml (removed in triple-c#32) never worked safely
|
||||
# as an automatic trigger: this repo's releases are assembled by
|
||||
# build-app.yml across three separate platform jobs, and there is no single
|
||||
# automatic event that fires only once everything (including the Linux .deb
|
||||
# this workflow needs) is actually uploaded. A human deciding "this release
|
||||
# is ready, go package it" is the correct trigger, the same reasoning
|
||||
# backfill-releases.yml already uses for its own manual-only GitHub sync.
|
||||
#
|
||||
# ## What this does and does not do
|
||||
#
|
||||
# It renders `packaging/arch/PKGBUILD` for one specific version (real
|
||||
# download URL, real sha256sums — never guessed; see the resolve-asset step),
|
||||
# validates it with `makepkg`/`namcap` in a real Arch container, and uploads
|
||||
# the resulting `.pkg.tar.zst` to the GitHub release it was built from —
|
||||
# installable by hand with `pacman -U`. It does NOT commit anything back to
|
||||
# this repo — `packaging/arch/PKGBUILD` stays a hand-maintained template with
|
||||
# a placeholder version, and the workflow never starts from or writes to it.
|
||||
#
|
||||
# ## Not published to the AUR (yet)
|
||||
#
|
||||
# This originally also pushed the rendered PKGBUILD to an AUR git repo, which
|
||||
# needs a maintainer AUR account and its SSH key registered as a secret here
|
||||
# — both manual, one-time steps neither this workflow nor anyone but a
|
||||
# maintainer can do. Until that setup happens, a downloadable release asset
|
||||
# gets the same package to users without it. The AUR push step is still in
|
||||
# this file's git history (see the commit that added this comment) if that
|
||||
# setup is ever done and it's worth reinstating.
