# CI Requirements — ThoughtSync

> Spec lives in [`docs/process.md`](https://git.fabledsword.com/bvandeusen/CI-runner/src/branch/main/docs/process.md)
> in the CI-Runner repo.

## Runtime image

```
git.fabledsword.com/bvandeusen/ci-python:3.14
```

Selected via `container.image` (not a `runs-on` label) on all four jobs in
`.forgejo/workflows/ci.yml`: typecheck (Vue/TS), lint (ruff), test (pytest),
build (docker buildx).

## Image deps used

- python 3.12+ (the runtime `Dockerfile` targets python:3.12-slim; tests run on
  the image's 3.14 — both >=3.12, so results stay representative)
- node 24 — `npm ci` + `vue-tsc` in the typecheck job, and the frontend builder
  stage inside the production `Dockerfile`. (Also required by the JS-based
  `actions/checkout` action — a Node-less runner fails every job at checkout.)
- ruff — lint job runs `ruff check src/` with zero install overhead
- uv — test job creates the venv (`uv venv /opt/venv`) and installs the package
  with dev deps
- docker CLI + buildx — build job pushes the dev/release image to the Fabled-Git
  registry

## Per-job tool installs

Nothing installed at job time beyond what the image provides — all four jobs run
entirely on `ci-python:3.14`.

## Notes

- **No `actions/cache`.** Deliberately omitted for npm/uv: it's a GitHub-fetched
  JS action and on a cold runner concurrent jobs race fetching it. We lean on the
  pinned `ci-python` image's pre-installed toolchain instead; `npm ci` / `uv pip
  install` cold cost is a non-blocker.
- Build gates on `typecheck` + `lint` only. The `test` job runs in parallel for
  visibility but does not block the dev image push. DB-backed / integration tests
  run against the dev image manually — ThoughtSync's unit tests are DB-free (no
  Postgres service lane in CI yet).
- `dev` push -> `:dev` + `:<sha>`; `v*` tag -> `:latest` + `:<version>` + `:<sha>`
  (family rule 46).
- The production runtime `Dockerfile` tracks python:3.12 so test results stay
  representative of the deployed image.
- **Artifacts — use the mirrored upload action, never `actions/upload-artifact`.**
  ```yaml
  uses: https://git.fabledsword.com/bvandeusen/upload-artifact@cb8afe72b42edc798abfb8fcb556cf660d894245
  ```
  Upstream's `actions/upload-artifact@v4` cannot work against this instance and
  no server-side change will help: its `isGhes()` rejects any hostname that isn't
  `github.com` / `*.ghe.com` / `*.localhost` and throws before it opens a
  connection, so the server is never asked what it supports. `@v3` is worse — it
  reports success, and Gitea then serves artifacts back only through the v4 API
  (`content_encoding = application/zip`), so a v3 upload is stored but invisible
  to every retrieval path. A green job producing nothing retrievable.

  `bvandeusen/upload-artifact` is our pull mirror of `forgejo/upload-artifact`
  (the Forgejo project's fork, one commit on upstream v5.0.0 disabling that
  check). Mirrored so CI depends on a commit we hold; pinned by SHA because the
  mirror auto-syncs and a moved upstream tag would otherwise change what runs.

  Both desktop upload steps also set `if-no-files-found: error` and carry **no**
  `continue-on-error`. They previously had both defaults inverted, which is how
  110 unreachable artifacts accumulated on this repo without anyone noticing —
  the upload could fail or match nothing and the run still went green. Scribe
  issues 2255 / 2270 have the full teardown.

  Download: `GET /api/v1/repos/{owner}/{repo}/actions/runs/{run_id}/artifacts`
  for the id (global run id, not the repo-scoped run number), then
  `…/actions/artifacts/{id}/zip`. Note the workstation has no `unzip` — use
  `python3 -m zipfile -e`.

## Desktop (Tauri) lane — separate workflow

The Tauri desktop client (`desktop/`) builds in its own workflow,
`.forgejo/workflows/desktop.yml`, NOT in `ci.yml` — it's a heavy Rust + AppImage
build (~20–40 min) that should only run on `desktop/**` changes, not on every
backend/frontend push.

- **Image:** `git.fabledsword.com/bvandeusen/ci-tauri:1.97` (Rust + Node +
  WebKitGTK 4.1 + Tauri v2 Linux deps + `tauri-cli`). Selected via
  `container.image`; `runs-on: python-ci` is only a scheduling label.
- **Steps:** build the shared frontend (embedded by `generate_context!`) →
  `cargo tauri icon app-icon.png` (platform icon set from the committed 1024px
  source) → `cargo fmt --check` → `cargo clippy -D warnings` → `cargo test` →
  `cargo tauri build` (produces `.deb` + `.AppImage`) → de-bundle the AppImage's
  graphics libs → verify the `.deb` → repackage for pacman.
- **`APPIMAGE_EXTRACT_AND_RUN=1`** is set: AppImage tooling FUSE-mounts by default
  and CI containers have no `/dev/fuse`.
- **Packaging tools used from the image** (none installed at job time, rule 5):
  `dpkg-deb` / `dpkg-query` / `apt-cache` and `dpkg-shlibdeps` (from `dpkg-dev`,
  pulled in by `build-essential`) for `desktop/packaging/deb/verify.sh`; `tar` +
  a compressor for `desktop/packaging/arch/package-prebuilt.sh`. Both scripts
  degrade gracefully rather than hard-failing on an absent optional tool:
  `bsdtar` (`libarchive-tools`) is used for the pacman package's `.MTREE` when
  present and skipped when not, compression falls back zstd → xz → gzip, and the
  `.deb` clean-container install test runs only if a docker CLI is available.
  Run 2872 confirmed all three optional tools are ABSENT today, so the current
  build takes every fallback: the pacman package ships as `.pkg.tar.xz` with no
  `.MTREE`, and the `.deb` clean-container install test is skipped. All three are
  functional outcomes — pacman installs an `.xz` package fine, and only
  `pacman -Qkk` file verification needs `.MTREE`. Adding `libarchive-tools` +
  `zstd` + a docker CLI to `ci-tauri` would upgrade these paths; none of them
  block a green build.
- **`libssl-dev` + `pkg-config` are load-bearing** (both already in `ci-tauri`).
  Since M10.6 the desktop crate depends on `reqwest` with the **`native-tls`**
  backend, which on Linux compiles against OpenSSL. Do NOT drop either package
  from `ci-tauri` in a future slim-down — the Rust build fails at `openssl-sys`.
  (They're part of Tauri's own documented Linux prerequisites, so they should
  stay regardless.)
- **`libssl3` is covered transitively, on purpose — don't "fix" it.** Since
  M10.6 `dpkg-shlibdeps` lists `libssl3` among the binary's needs, but the
  `.deb` declares only `libwebkit2gtk-4.1-0` + `libgtk-3-0`. `verify.sh` passes
  it because webkit's own recursive dependency closure includes OpenSSL, so apt
  installs it either way. Declaring it explicitly would be *worse*: the package
  name is release-dependent (`libssl3` on bookworm, `libssl3t64` after the
  64-bit-time_t transition in trixie/Ubuntu 24.04), so a hardcoded name freezes
  the package to the build distro. Leaning on webkit's closure adapts. If webkit
  ever stops pulling OpenSSL, `verify.sh` fails the build loudly — that guard is
  what makes the indirection safe.
- **Not verifiable in CI:** the runner is Debian, so the pacman package cannot be
  `pacman -U`-tested here. That step logs `.PKGINFO` + the full file listing so
  the package is auditable from the run log; a real Arch install is the operator's
  confirm.

### Windows lane — second job, second image

`desktop.yml` also runs a `windows` job that cross-compiles the NSIS installer.

- **Image:** `git.fabledsword.com/bvandeusen/ci-tauri-win:1.97` (Rust + Node +
  `cargo-xwin` + LLVM/`lld` + NSIS). A separate image from `ci-tauri` per
  CI-Runner's `docs/process.md` fork rule — the MSVC CRT/SDK cache alone is >1 GB.
  Its pins are held in lockstep with `ci-tauri`; bump them together, since both
  lanes compile the same source.
- **Why cross-compile:** there is no Windows build host, and a Windows container
  cannot run on a Linux host (containers share the host kernel). `cargo-xwin`,
  `lld-link` and `makensis` are Linux programs that emit Windows PE output.
- **NSIS only.** `.msi` requires WiX v3, a Windows program — per Tauri, "`.msi`
  installers can only be created on Windows."
- **Separate job on purpose:** a Windows failure must not block the Linux
  artifacts, which are the primary product today.
- **Weakest verification of any lane.** Tauri documents this path as "not as
  straight forward as compiling on Windows directly and is not tested as much",
  to be used "only as a last resort" — and a Linux runner cannot execute a
  Windows binary. Green means it *built*. A real Windows machine check is
  mandatory before trusting a release.
- **Unsigned.** Installers will trip SmartScreen until a code-signing
  certificate exists; that is a purchasing decision, not a CI one.
- **TLS backend is chosen for this lane's sake.** The desktop crate pins
  `reqwest` to `native-tls`, which on `x86_64-pc-windows-msvc` resolves to
  `schannel` — pure-Rust bindings to the OS TLS stack. That keeps C/assembly out
  of the cross-compile entirely. Switching to `rustls` would pull in
  `ring`/`aws-lc-rs` and their assembler, which is exactly the class of
  dependency that broke this lane before (`libsqlite3-sys` → `llvm-lib`). Treat
  a TLS-backend change as a change to *this lane*, not just a dependency bump.
- No Postgres lane (unchanged): the desktop app's local store + sync behavior is
  verified on the operator's machine, not in CI.

## Android lane — REMOVED 2026-08-17

The Tauri-mobile Android lane is gone. Android is a native Kotlin/Compose client
over the shared `thoughtsync-core` crate instead — see Scribe note 2730 for the
decision and milestone M12 for the arc. Its CI lane and image will be rebuilt on
that basis; `ci-tauri-android` is being repurposed (drop `tauri-cli`, add
`cargo-ndk`) rather than deleted, because its NDK binutils symlinks and PATH fix
are load-bearing for any Rust-on-Android cross-compile.

## Formatting the Rust lane before pushing

`cargo fmt --check` runs in CI and had failed on four consecutive desktop pushes
by itself, each costing a full cycle to learn a whitespace nit. There is no Rust
toolchain on the workstation (rule 10), but the CI image is pullable, and running
a formatter is neither a test run nor a local stack:

```
docker run --rm --user "$(id -u):$(id -g)" -e CARGO_HOME=/tmp/cargo \
  -v "$PWD:/w" -w /w \
  git.fabledsword.com/bvandeusen/ci-tauri:1.97 cargo fmt --all --check
```

Drop `--check` to apply. `--user` keeps the container from leaving root-owned
files behind; `CARGO_HOME` points somewhere writable for that user.

**Don't infer formatting from existing code.** Several lines in `local/store.rs`
exceed 100 characters and survive only because rustfmt cannot break a string
literal — copying that shape caused one of the four failures.

## The desktop lockfile

`Cargo.lock` is **committed** at the workspace root, per Cargo's own guidance for
binary crates. Without it every CI run re-resolved the graph, which meant a
released `.deb`/`.AppImage`/`.exe` couldn't be rebuilt from its tag, a build
could break with no repo change, and Renovate had nothing to bump (issue 2102).

Enforced by `--locked` on each job's **first** cargo invocation — `cargo clippy
--locked` on Linux, a dedicated `cargo fetch --locked --target
x86_64-pc-windows-msvc` step on Windows. If the manifest and the lockfile
disagree, the run fails there instead of silently re-resolving; everything after
it in the same job then compiles the recorded versions, so the flag isn't
repeated on the bundle build. The Windows step exists separately because that
job's only crate-graph command is the cross-compile itself, and drift is cheaper
to learn in the first thirty seconds than thirty minutes in.

To regenerate it after a dependency change — same reasoning as `cargo fmt`
above, and resolution is neither a test run nor a build:

```
docker run --rm --user "$(id -u):$(id -g)" -e CARGO_HOME=/tmp/cargo \
  -v "$PWD:/w" -w /w \
  git.fabledsword.com/bvandeusen/ci-tauri:1.97 cargo generate-lockfile
```

Resolving inside the CI image rather than against some other cargo is what keeps
the lockfile format and the picked versions identical to what CI would have
chosen. Commit the result in the same change as the `Cargo.toml` edit — a
manifest change pushed without it fails the gate.

## Pushing: `dev` is both a branch and a tag

`git push origin dev` fails in this repo:

```
error: src refspec dev matches more than one
```

The rolling update channel is a release on a **fixed tag named `dev`** (the tag
never moves — Fabled-Git has no `/releases/latest/download/<asset>` route, so the
updater needs a permanent URL). Once that tag is fetched locally, the short name
`dev` resolves to both `refs/heads/dev` and `refs/tags/dev`. Fully qualify it:

```
git push origin refs/heads/dev:refs/heads/dev
```

## Shell scripts have no CI lane

Nothing lints `desktop/packaging/*.sh`, and a broken installer or publish script
fails at the moment a user runs it, not in a build. Check them before pushing —
`install.sh` is POSIX sh, the rest are bash:

```
dash -n desktop/packaging/install.sh          # or: sh -n
bash -n desktop/packaging/publish-release.sh
```

Where a script resolves URLs from the Fabled-Git API, exercise the resolution
against the live instance (plain `curl` reads, no install) rather than trusting
the regex by eye. Both channel paths in `install.sh` were verified that way.

**Hand-assembled JSON: parse it before you push it.** `publish-release.sh` builds
its request bodies as shell strings, and quoting context decides what survives
into the JSON — a `` \ `` inside an unquoted heredoc loses its backslash to the
shell, the same `` \ `` inside a single-quoted variable does not, and reaches
Fabled-Git as an illegal escape (HTTP 422, one wasted build). `sh -n` cannot see
this. Extract the body block and parse it for every branch it can take:

```
sed -n '/^# The install command printed/,/^JSON$/p' desktop/packaging/publish-release.sh > /tmp/body.sh
echo ')' >> /tmp/body.sh
bash -c 'GITHUB_SERVER_URL=https://git.fabledsword.com GITHUB_REPOSITORY=o/r \
  TAG=dev RELEASE_PRERELEASE=true; . /tmp/body.sh; printf "%s" "$BODY" | python3 -m json.tool >/dev/null'
```
