The fallback key is also read by the AppImage installs of v0.4.2 to v0.4.5 (bundled until v0.7.3, published on Forgejo for v0.4.2-v0.4.3 and on the GitHub mirror for v0.4.3-v0.4.5, all reading the registry), which look up linux-x86_64-appimage, absent, then linux-x86_64. Like a marker-less binary, they cannot install the .deb it serves: the updater writes its bytes over the running AppImage. State since v0.4.2, not changed by this PR; the key stays as decided. Also quote the error the update card really shows for a refused package (invalid updater binary format). Refs #320 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# Build latest.json, the updater manifest of a release, from its assets (#320).
|
|
#
|
|
# Usage: build-latest-json.sh <assets-dir> <version> <notes-file> <base-url>
|
|
#
|
|
# assets-dir directory holding the bundles and their .sig files
|
|
# version release version without the leading v, e.g. 0.17.1
|
|
# notes-file release notes, embedded verbatim as data (jq --rawfile)
|
|
# base-url download URL of the release, without a trailing slash, e.g.
|
|
# https://<forgejo>/<owner>/<repo>/releases/download/v0.17.1
|
|
#
|
|
# Writes the JSON on stdout and its log on stderr. release.yml redirects
|
|
# stdout to release-assets/latest.json; scripts/build-latest-json.test.mjs
|
|
# runs it under bash -e -o pipefail, as the CI runner does.
|
|
#
|
|
# Fails closed: unless the assets dir holds exactly one .deb, one .rpm and
|
|
# one -setup.exe, each with a non-empty "<asset>.sig" next to it, the script
|
|
# exits non-zero before writing anything on stdout. The JSON is built by jq
|
|
# alone: notes, file names and signatures enter it as jq values, never as
|
|
# text spliced into JSON.
|
|
#
|
|
# Keys. tauri-plugin-updater 2.x looks up "{os}-{arch}-{installer}" first,
|
|
# then "{os}-{arch}" (get_urls in its updater.rs). The installer is the
|
|
# bundle type that the bundler writes into the binary of each package.
|
|
#
|
|
# linux-x86_64-deb the .deb, for .deb installs.
|
|
# linux-x86_64-rpm the .rpm, for .rpm installs. Without this key they fell
|
|
# back on linux-x86_64, downloaded the .deb and refused it.
|
|
# linux-x86_64 the .deb again: the fallback of a binary without a
|
|
# bundle-type marker, which looks up this key alone.
|
|
# Remove it once no supported version predates the
|
|
# marker. AppImage installs (v0.4.2 to v0.4.5) read it
|
|
# too, and neither they nor a marker-less binary can
|
|
# install a .deb: see docs/qa-update-cycle.md, "Les
|
|
# clés de latest.json".
|
|
# windows-x86_64 the NSIS installer. An NSIS install looks up
|
|
# windows-x86_64-nsis first, then this key.
|
|
#
|
|
# Each URL ends with the file name percent-encoded by jq's @uri, as the upload
|
|
# step of release.yml encodes it: the bundle names contain a space.
