pisti87's T-Deck rebooted every time he logged into a repeater, but only in
Hungarian. The login clock-skew warning does:
snprintf(msg, n, TR("Device clock differs from \"%s\" by %lu min%s"),
name, minutes, suffix);
and the Hungarian row reordered the conversions to "%lu ... %s ... %s". Varargs
are positional, so snprintf read the name POINTER as an unsigned long and then
took the minute count -- the integer 3 -- as a char* and dereferenced address 3.
Instant panic, every login, Hungarian only. English fit the declared order, so
it never showed there.
Fixing the four bad Hungarian rows is not sufficient: TR() returns a format
string and translations come from .lang files that users download or hand-write,
so any file can crash any device. TR() now compares the ordered conversion
signatures of key and translation and falls back to the English key on a
mismatch -- the key IS the call site's format string, so it is always correct.
The scan runs only for keys containing '%', which is a small minority.
Also fixed the four rows (three were Hungarian-only crashes or dropped values),
bumped hu to v11, and taught audit-lang.py to fail the build on a mismatch so a
future translation PR cannot reintroduce this. Unit-checked that the audit
detects the original bad row and accepts the repaired one.

wadamesh.com infrastructure
Distribution stack for wadamesh: a VPS nginx origin behind Cloudflare.
tiles.wadamesh.com →CF (HTTP, edge-cached) → nginx → OpenStreetMap / OpenTopoMap
firmware.wadamesh.com →CF (cache bins) → nginx → /srv/wadamesh/firmware
flasher.wadamesh.com →CF (HTTPS) → web flasher (TODO — see below)
wadamesh.com →CF (HTTPS) → landing page (later)
Map tile styles. The default /{z}/{x}/{y}.jpg route serves OpenStreetMap
(the firmware default). An opt-in OpenTopoMap topographic style is served from
/opentopo/{z}/{x}/{y}.jpg (explicit OSM alias at /osm/...); the device requests
it only when the user enables Map → Options → Topographic map. Legal: OpenTopoMap
map tiles are © OpenTopoMap (CC-BY-SA) over © OpenStreetMap contributors
(ODbL) + SRTM — the touch UI shows that attribution when topo is active, and the
14-day disk cache keeps each tile hitting OpenTopoMap at most once per fortnight
(their tile-usage policy asks for a contactable UA + caching, both of which the
transcode service provides). Deploying the topo routes = update
tiles.wadamesh.com.conf + tile-transcode.py, then
systemctl restart wadamesh-tile-transcode && nginx -t && systemctl reload nginx
and purge the Cloudflare cache for tiles.wadamesh.com/opentopo/*.
The firmware fetches tiles + the update-check over plain HTTP (on-device HTTPS isn't viable — mbedTLS needs ~30 KB heap, only ~5 KB is free post-Wi-Fi), so the tile + firmware hosts must stay reachable over HTTP. Cloudflare provides the edge cache, HTTPS for the flasher, and hides the origin IP (so no IP lives in this repo or the firmware).
1. VPS (origin)
sudo apt install nginx
sudo mkdir -p /srv/wadamesh/firmware/releases/TOUCH /var/cache/nginx/wadamesh-tiles
sudo cp deploy/nginx/tiles.wadamesh.com.conf /etc/nginx/sites-available/
sudo cp deploy/nginx/firmware.wadamesh.com.conf /etc/nginx/sites-available/
sudo ln -s /etc/nginx/sites-available/tiles.wadamesh.com.conf /etc/nginx/sites-enabled/
sudo ln -s /etc/nginx/sites-available/firmware.wadamesh.com.conf /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx
2. Cloudflare
- DNS:
A/AAAArecords fortiles,firmware,flasher,@→ the VPS IP, all Proxied (orange cloud). - SSL/TLS: mode Flexible (CF↔origin HTTP) is enough since the origin is
HTTP-only. Do NOT enable "Always Use HTTPS" on
tiles.orfirmware.— the firmware needs plain HTTP there. - Cache Rules:
tiles.wadamesh.com/*→ Eligible for cache, Edge TTL ~14d.firmware.wadamesh.com/releases/*/*.bin→ cache, Edge TTL ~1d.firmware.wadamesh.com/releases/TOUCH(the listing) → short TTL (~60s) or Bypass, so new releases appear promptly.
3. Publishing a release
From a wadamesh checkout (builds both boards, refreshes the listing, rsyncs up):
WADAMESH_VPS=user@your-vps scripts/release.sh beta_2
The on-device check GETs http://firmware.wadamesh.com/releases/TOUCH, finds the
highest beta_<N>, and (once OTA-over-Wi-Fi is re-enabled) pulls
…/releases/TOUCH/beta_<N>/<board>.bin.
Done
- Web flasher ✅ at
flasher.wadamesh.com—deploy/flasher/(esp-web-tools / Web Serial, board picker, manifests pointing at the rolling/latest/merged bins;release.shrefreshes/latest/each publish). - Apex
wadamesh.com301-redirects to the flasher — activate by pointing thewadamesh.comA record at the VPS in Cloudflare (it's still on the parking IP).
TODO before public launch
- Re-enable OTA-over-Wi-Fi in the firmware (currently it version-checks then defers to manual flashing).
- Flip
wadameshrepo public = launch. - Decide tile-proxy sharing: dedicated
tiles.wadamesh.com(this config) vs reusing the meshcomod proxy.
Never commit the VPS IP, SSH keys, or
WADAMESH_VPS. Cloudflare fronts the origin; the deploy target is supplied via the environment at publish time.
