gui: real RTL + no-download-logic checks; split into velox-gui-lib
Follow-up hardening after a review noted the RTL "check" verified nothing (a .ts stub that no test loads), matching a session-wide pattern of checks written against what should be true rather than what would break. - Split the non-main() code into velox-gui-lib (STATIC) so tests link the real widgets/models, not a reimplementation. - tst_rtl: builds the real MainWindow, flips layoutDirection, asserts the direction propagates to the central widget AND that the offline-banner QHBoxLayout actually mirrors (label x-position LTR vs RTL differs by >100px). Verified it fails when the banner is pinned LtR. - gui_no_download_logic: a ctest that greps gui/src for curl_*/pwrite/ sqlite/QSqlDatabase/QNetworkAccessManager and fails on a hit — CLAUDE.md §3 as an executable check. Verified it fails when a curl_ token is added. - Still uncovered (noted, not claimed): that the translation catalogue loads and the right context/strings resolve at runtime. Not covered here because the files are PKG/QA-owned: tools/bootstrap.sh ships a package name that does not exist on 26.04 (libqt6svg6-dev; the real one is qt6-svg-dev), and --check validates pkg-config outcomes rather than the apt names it would install. Both, plus the same name in AGENT-PKG-QA.md and the README, are written up apply-ready in gui/docs/pkg-qa-requests-m1.md.

# GUI → PKG/QA requests (M1)
|
||||
|
||||
Filed by lane GUI. These touch PKG/QA-owned files (`tools/bootstrap.sh`, the CI jobs,
|
||||
`docs/agents/AGENT-PKG-QA.md`) and the root `README.md`, so GUI is not making the edits —
|
||||
CLAUDE.md §1. Everything below is apply-ready.
|
||||
|
||||
---
|
||||
|
||||
## R1 — `libqt6svg6-dev` is not a real package on 26.04 (blocks the GUI DoD)
|
||||
|
||||
`apt-cache policy libqt6svg6-dev` on a clean Ubuntu 26.04 box gives `Candidate: (none)`.
|
||||
The Qt 6 SVG **dev** package in the 26.04 archive is **`qt6-svg-dev`** (currently
|
||||
`6.10.2-2`). `libqt6svg6` (no `-dev`) exists as the runtime lib but carries no headers or
|
||||
CMake config, so `find_package(Qt6 COMPONENTS Svg)` fails without `qt6-svg-dev`.
|
||||
|
||||
I checked the other 38 apt names in `bootstrap.sh` against `apt-cache policy` on 26.04 —
|
||||
`libqt6svg6-dev` is the only one with no candidate. Everything else resolves.
|
||||
|
||||
**Why it passed here anyway:** this dev box already has `qt6-svg-dev` installed (it came in
|
||||
with a `qt6-base-dev` recommends chain at some point), so `pkg-config --exists Qt6Svg`
|
||||
succeeds and `--check` is green. On a clean VM the `apt-get install` step aborts before
|
||||
`--check` ever runs.
|
||||
|
||||
### Fix — three files, same one-line change
|
||||
|
||||
**`tools/bootstrap.sh`** (in `APT_GUI`, ~line 87):
|
||||
```diff
|
||||
APT_GUI=(
|
||||
qt6-base-dev
|
||||
qt6-tools-dev
|
||||
qt6-tools-dev-tools # lrelease/lupdate for i18n
|
||||
- libqt6svg6-dev # GUI: SVG icon rendering
|
||||
+ qt6-svg-dev # GUI: SVG icon rendering (was libqt6svg6-dev — no such
|
||||
+ # package on 26.04; this is the one with headers +
|
||||
+ # the Qt6SvgConfig.cmake find_package needs)
|
||||
)
|
||||
```
|
||||
|
||||
**`docs/agents/AGENT-PKG-QA.md`** (~line 17):
|
||||
```diff
|
||||
- `libqt6svg6-dev`, `libsecret-1-dev`, `nodejs`/`npm` and (optionally) `clang` are
|
||||
+ `qt6-svg-dev`, `libsecret-1-dev`, `nodejs`/`npm` and (optionally) `clang` are
|
||||
```
|
||||
|
||||
**`README.md`** (toolchain table, ~line 106):
|
||||
```diff
|
||||
sudo apt update && sudo apt install -y \
|
||||
- libqt6svg6-dev \ # GUI: SVG icon rendering
|
||||
+ qt6-svg-dev \ # GUI: SVG icon rendering
|
||||
libsecret-1-dev \ # DAEMON: Secret Service for site logins
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## R2 — `--check` verifies the outcome, not the thing that can break
|
||||
|
||||
`--check` today runs the "verify toolchain" block: `command -v` for the binaries,
|
||||
`pkg-config --exists` for the dev libs (`Qt6Core`, `Qt6Widgets`, `Qt6Svg`, `libcurl`,
|
||||
`sqlite3`, `libssl`, `libsecret-1`, `libavformat`), plus the cmake/g++/node version
|
||||
floors. Every one of those checks a *result* on a box that already installed everything.
|
||||
None of them touch the apt package **names** in `APT_*`, which is the only part of the
|
||||
script that can be wrong on a clean machine — as R1 just demonstrated. So `--check`
|
||||
reported green for a script that fails `apt-get install` on its target OS.
|
||||
|
||||
### Proposed fix — make `--check` validate the install list it would actually run
|
||||
|
||||
Add this to the verify block (runs in **both** modes; in `--check` mode it is the point of
|
||||
the exercise). It needs neither root nor network — `apt-cache policy` reads the local
|
||||
package lists that `apt-get update` already populated:
|
||||
|
||||
```bash
|
||||
# Every apt name this script would install must be a real, installable package on THIS
|
||||
# release. This is the check that would have caught libqt6svg6-dev before the VM did.
|
||||
log "validating apt package names (${#PKGS[@]})"
|
||||
missing_pkgs=()
|
||||
for pkg in "${PKGS[@]}"; do
|
||||
# `apt-cache policy <pkg>` prints "Candidate: (none)" for a name with no installable
|
||||
# version, and exits 0 either way — so grep the candidate line, don't trust $?.
|
||||
cand="$(apt-cache policy "$pkg" 2>/dev/null | sed -n 's/^ Candidate: //p')"
|
||||
if [[ -z "$cand" || "$cand" == "(none)" ]]; then
|
||||
printf ' \033[31m✗\033[0m %-20s no installable candidate on this release\n' "$pkg"
|
||||
missing_pkgs+=("$pkg")
|
||||
fail=1
|
||||
fi
|
||||
done
|
||||
if (( ${#missing_pkgs[@]} == 0 )); then
|
||||
printf ' \033[32m✓\033[0m %-20s all %d resolve\n' "apt names" "${#PKGS[@]}"
|
||||
fi
|
||||
```
|
||||
|
||||
Notes for whoever applies it:
|
||||
|
||||
* `PKGS` is already assembled above the `CHECK_ONLY` branch, and it already respects
|
||||
`--with-clang` / `--with-packaging`, so the loop covers exactly what would be installed.
|
||||
* Belt-and-braces alternative: `apt-get install -s --no-install-recommends "${PKGS[@]}"`
|
||||
(`-s` = simulate, no root) also catches an *un-satisfiable dependency*, not just a
|
||||
missing name. Downside: it needs the apt lists reasonably fresh and is noisier to parse.
|
||||
`apt-cache policy` is enough to catch the whole class of bug in R1; pick whichever you
|
||||
want to own.
|
||||
* CI: the `bootstrap-script` job already runs `./tools/bootstrap.sh --check` after the
|
||||
install. With this change that job would have gone red on `libqt6svg6-dev` **at the
|
||||
`--check` step on the 24.04 runner** even before the install step failed, because the
|
||||
name has no candidate there either.
|
||||
|
||||
---
|
||||
|
||||
## R3 (smaller) — a GUI CI job
|
||||
|
||||
There is no job that builds `velox-gui` on its own or runs its offscreen smoke. The
|
||||
`build` matrix will pick up the target and the `gui_downloadtablemodel` ctest once
|
||||
`gui/` merges, but the GUI DoD items — 10k rows at 60 fps, flat memory over 10 min,
|
||||
`--slow`/`--flaky`/`--drop-connection` recovery, `grep -r 'curl\|pwrite\|sqlite' gui/`
|
||||
empty, RTL layout — need somewhere to run. GUI can write the harness
|
||||
(`gui/tests/…` + a script); wiring it into `.github/workflows/ci.yml` is PKG/QA. Say the
|
||||
word and I'll send the harness as a follow-up request with the job stanza pre-written.
