cloud-sync now ships a real Qt UI alongside the tkinter fallback.
Architecture:
- HeadlessProgress: --no-gui path, plain stdout
- TkProgressWindow: stdlib fallback when Qt isn't installed
- QtProgressWindow: preferred path; supports both PySide6 and PyQt6
(interchangeable APIs for our subset)
The factory in ui.py picks Qt → tkinter → headless. Tk stays so the
zipapp still works on bare Python with no extras.
Threading: QApplication runs on the main thread (started by run_with
via QDialog.exec). The restic worker runs on a daemon threading.Thread.
Cross-thread UI updates go via a Signal on a bridge QObject so Qt
auto-marshals them onto the main thread via a queued connection.
Cancellation: WM close + Cancel button both set a flag. sync.pull/push
pass ui.is_cancelled as restic.run's cancel_check; the subprocess gets
killed and returns -1 → exit 1.
Theme: Fusion style + Prism's dark palette (RGB values copied as facts
from PrismLauncher's DarkTheme.cpp). Override with PRISM_THEME=off.
Pyz size went 20 KB → 36 KB (added ui.py + ui_qt.py).
33 tests still green.
Reasons stacked up:
- AV: unsigned JARs that auto-download binaries + upload files trigger
Windows Defender false-positives more often than Python scripts
invoked by code-signed python.exe.
- Qt UI option: PySide6 opens a path to a real Qt UI (matching Prism's
look) if needed later. JVM Qt bindings are abandoned.
- frazclient already needs Python; inlining as 'import cloud_sync' is
zero overhead vs the launcher always shelling out to java.
Implementation:
- cloud_sync package: cli.py (argparse), creds.py, scope.py,
restic.py (binary discovery + auto-download + sha256 verify),
sync.py (pull/push subprocess restic).
- pyproject.toml with hatchling backend; pip-installable.
- Makefile builds cloud-sync.pyz via python -m zipapp (~53 KB).
- 33 pytest tests, stdlib only on runtime.
- CI workflow runs pytest matrix (3.10/3.11/3.12) + builds pyz.
- DESIGN.md + README.md updated to reflect Python.
E2E verified against local restic-rest-server:
pull empty → push initial → rm -rf local → pull restores → modify+push
creates second snapshot → client forget --prune blocked by --append-only.
Throws away ~565 LOC of Kotlin (and 18 jar tests) committed earlier in
this same session. Net result is ~250 LOC Python + 33 tests = smaller
and more aligned with the rest of the stack.
