The channel sends through the Bot API with httpx only: HTML with escaped text,
cut to fit a message, silent for a warning, a short 429 waited out once, and
errors that say what to do about a blocked bot, a lost chat or a bad token and
never quote the request URL. The bot token is a stored secret: saving a
channel refuses a literal one, the card's "Store token" writes the secret and
a reference, and no endpoint returns it.
A chat id is never typed. Connect starts a ten minute code, and the chat that
sends `/start <code>` back through the bot is the one connected, so it is a
chat somebody opened a link for. The engine fetches updates only while a code
is waiting (no standing poll, no webhook, no inbound address) and ignores
everything else without a reply. Connect needs a saved form, and the form
takes the connected chat in without touching what was typed since.
The token is part of every Bot API URL, so the httpx logger gets the same
filter the request lines have, which now also masks an httpx.URL argument.
Any signed-in account could save an ntfy channel with its own `server` and a
`{"$secret": ...}` token and press Test, which sent the stored secret to that
host. The config GET/PUT, the test route and the global search's alert entries
now answer to superusers, like /secrets. The webpush key and subscribe routes
stay open to every account, and the Alerts page shows a non-superuser only the
button for its own browser. The events table in the docs gains run_finished.
A `webpush` alert channel, and the PWA it needs to arrive. The payload is
encrypted to the subscription (RFC 8291) and the request signed with this
installation's own keypair (RFC 8292), both over `http-ece` — `pywebpush`
does the same in one call but brings `requests` and `aiohttp` with it, two
HTTP stacks beside httpx on a machine that may be a Raspberry Pi.
The manifest and the worker are hand-written rather than `vite-plugin-pwa`:
there is nothing worth precaching when the page carrying the credential is
`no-store`, so the worker handles `push` and `notificationclick` and nothing
else. `registration.scope` is the app's root in both places it runs, which is
why the payload carries no URL.
A run finishing in error is the first event worth waking someone for; `ok`
and `cancelled` describe to nothing, so a nightly batch that works stays
quiet. The events were already on the bus — only the filter changed.
`WEBPUSH_FILE` is a derived path, so the keypair lands on the data volume
with the alerts beside it. Off it, a rebuild would silently stop every phone
being notified: the key they subscribed against would be gone.
A wheel whose top-level module is `app` collides with anything else in a
user's venv, so the package that is about to be published takes the name
it is published under. Only the Python package moves; the repo, the
Docker WORKDIR and the compose project keep theirs.
