Session - COOKIE_SECURE=false no longer persists the owner key for ten years. services/session.cookie_kwargs() drops max_age in that mode, so the browser holds the key in memory and the session ends with the window. Everything still persists server-side; only the browser link is temporary. base.html shows a warning banner (FR/EN) and an extra paragraph in the onboarding modal, and the README explains the trade-off and the backup-key escape hatch. - Both cookie writers (middleware, POST /session/restore) go through cookie_kwargs() so the policy cannot drift between them. - The CSRF guard on /session/restore compared request.url.scheme against the Origin header. Behind a TLS-terminating proxy uvicorn sees http while the browser sends https, so every legitimate restore was rejected with 403. It now compares hosts only, including X-Forwarded-Host. - /static/*, /favicon.ico and /robots.txt skip the middleware. Each cookieless hit was inserting an Owner row no browser could ever use. Reliability - Malformed printer-form FK fields no longer escape as HTTP 500: a non-numeric client_id/driver_id raised ValueError and an unknown driver_id hit a FOREIGN KEY constraint. Both are now 400/404 HTMX fragments, and the duplicated field checks moved into _validate_fields(). - Package exports stream. build_intunewin() encrypts the inner ZIP in 1 MB chunks against temp files with a streaming HMAC and SHA256, and both endpoints serve the result with FileResponse plus a background cleanup task. A 100 MB driver used to be held in memory three or four times over per concurrent download. The byte layout is unchanged. - FileResponse also escapes the download filename, which was previously interpolated raw into Content-Disposition. - python-multipart >= 0.0.18 (CVE-2024-53981, reachable from /drivers/upload) and Pillow >= 10.3 (CVE-2024-28219, reachable from icon upload). - icons.py reads cfg.ICONS_DIR instead of re-deriving the path from DATA_DIR, matching the .intunewin export. UI - Sidebar/topbar shell, inline SVG icon macros (partials/icons.html), card and data-table components, grouped printer list, and the dedicated /printers/new page replacing partials/printer_form.html. Tests - 194 pass with a bare `pytest tests/`: tests/conftest.py now forces cfg.COOKIE_SECURE = False like the e2e conftest already did, so the Secure cookie is no longer dropped over http://testserver. - New coverage for the malformed-FK guards, the chunk-boundary cases in the encrypt loop (every residue mod _CHUNK plus a multi-megabyte payload), temp-dir cleanup after both exports, and the whole COOKIE_SECURE matrix. - test_printer_edit.py located the Edit button by its translated label, so it only passed on English-locale machines. It now targets the showModal() hook, which also cuts the e2e run from 84s to 15s. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
ImpTune
Build printer deploy packages (.intunewin for Intune, .zip for NinjaRMM) from Windows driver ZIPs via a web UI.
Run
Local development
docker compose up
docker-compose.override.yml is merged automatically: it mounts your working
copy into the container and runs uvicorn with --reload, so code edits are
picked up live. The override is gitignored (personal / per-machine).
Run the published image
To run the image from the registry instead of building locally, skip the override:
docker compose -f docker-compose.yml pull
docker compose -f docker-compose.yml up
Then open http://localhost:8000
Publishing
scripts/publish.ps1 builds the image and pushes it to the Gitea container
registry at git.azuze.fr/kawa/imptune.
# build + push :<short-git-sha> and :latest (prompts for a Gitea token)
./scripts/publish.ps1
# tag an explicit version
./scripts/publish.ps1 -Tag v1.2.0
Use a Gitea access token (Settings → Applications, with package read/write
scope) as the password. For non-interactive runs set GITEA_USER /
GITEA_TOKEN env vars. Run Get-Help ./scripts/publish.ps1 -Detailed for all
parameters (-Registry, -Owner, -Image, -NoBuild, -SkipLogin, …).
Environment variables
Set these under environment: in docker-compose.yml.
| Variable | Default | Purpose |
|---|---|---|
DATA_DIR |
/data |
Storage root for the SQLite DB, drivers and icons. Should map to the imptune_data volume. |
PORT |
8000 |
Port the server listens on inside the container. |
COOKIE_SECURE |
true |
Secure flag on the session cookie. Set to false when the app is reached over plain HTTP — see below. |
COOKIE_SECURE and HTTPS
Printers, print defaults and clients belong to a session identified by an opaque
key in a cookie (there are no accounts). That cookie is Secure by default, so
it only travels over HTTPS.
Behind a TLS-terminating proxy (nginx, Traefik, Caddy — the normal setup): leave the default. The session cookie lasts ten years, so a browser keeps its printers indefinitely.
Reached directly over plain HTTP (http://host:8000): set
COOKIE_SECURE=false, otherwise the browser refuses the cookie and every
request starts a brand-new empty session — no printer you save is ever visible
again.
In that mode the app is fully usable and keeps remembering everything, but the
cookie becomes memory-only: the session ends when the browser closes, and
every page shows a warning saying so. This is deliberate — over plain HTTP the
key is readable on the wire, so it is not written to disk for ten years. Use
Download my backup key to save the key to a file; /session/restore takes
it back on the next browser start, or on another machine.
