The backend image now builds the SPA and serves it on the API's own origin
(fluksio/spa.py), so an instance is a single container with no proxy, DNS,
port 80 or .env: `docker compose up -d` with the new compose.yml runs it on
localhost:8080. It starts on fluksio serve (persisted secret key, first
admin printed once) and brings its own Redis when REDIS_HOST is unset.
Slimmer: python:3.13-slim, no dev group, uv once, fastapi without the cloud
CLI. Optional features are per-feature extras (mqtt, influx, email, sentry,
ml, server for all) picked with the EXTRAS build argument; numpy moved to
`ml`. ffmpeg left the image for imageio-ffmpeg via the Modules screen.
The operator stack runs the same image with app. and api. routed to it; the
nginx frontend service, the LAN nginx proxy and DOMAIN in the backend are
gone, and the MCP issuer is FRONTEND_HOST.
run_coroutine_threadsafe refused it and it was never awaited, a RuntimeWarning
under pytest 9. The cancel still logs that it could not reach the worker.
The connector now serves /mcp, its OAuth documents and /hooks/ besides
/api/v1/, refuses any dot segment (httpx resolves them, which carried
/api/v1/../../mcp onto the MCP mount), addresses calls to the hub's host,
and bridges served sockets by calling the app with a websocket scope.
A hook without a secret answers the tunnel with the 404 (or 1008) of a
wrong secret. Requests through the hub get the hub's issuer, resource and
consent page in the OAuth metadata and the 401, and the MCP host check
admits the hub while enrolled.
CACHE_SHAPE_SINCE marks the last change that moved every cache key. The
run service's periodic sweep clears cache_key on rows of runs created
before it, which nothing can match any more. Their outputs stay.
Migration ccb21eacf5d5 deletes rows whose run is gone, then adds foreign keys
with ON DELETE CASCADE from run_node, run_metric and run_artifact to run.id.
Deleting runs is now the one statement. A node or metric written after its
run was deleted is dropped with an info line. Migrations run with foreign keys
off, since a batch rebuild of run would otherwise cascade into every child row.
Run.declared (migration 2e7ca7d10044) snapshots the declarations on submit
and import. The run detail's Inputs panel reads them, and a run from before
falls back to the flow's current declarations.
Its entries are the cards present, and a local child's allocation is
named through them, so under =2,3 card 0 is device 2. Remote workers
keep mapping against their own mask.
POST /observability/flush handles what the collector has queued and writes
it, so the soak harness no longer sleeps FLUSH_INTERVAL_S before clearing
its own rows.
DELETE /flows/library/{name} still answers 409 while nodes use the source.
With detach=true each of them keeps a copy of the code, in the published
flow and the draft, the source is deleted and the running users rebuild.
mqtt and http take websocket's vocabulary: their Mode is LISTENER/SENDER,
default names read mqtt_listener_… and http_listener_…, and mqtt's
publish_queue_size is send_queue_size. No alias stays behind, so the flow
store rewrites the old setting in every published and draft mqtt node when it
opens, in the same migration as trigger → debounce. Every mqtt and http
setting carries a one-line description for the editor, and the node-types
reference uses one wording for direction and says that an http sender
publishes a JSON object response on its outputs.
A push session that failed before it listened left only a task_crashed
event. The wrapper in _run_supervised now reports down with the exception,
unless the loop already said why it is down.
A flush ran its cascade under no id, so its executions and failures belonged
to no run. It now records a run with source "flush", and the holding run's id
travels on the queue item into a new `flow_run.parent` column, also on the
`/observability/runs` rows.
The store rewrites `"type": "trigger"` to `debounce` in every published and
draft flow when it opens, bumps the version and commits once. No alias stays
behind, so `trigger` is now an unknown type.
ws:// and wss:// URLs dial out and hold a supervised connection; a path is
served under /hooks/<flow>/ with an optional secret. Outputs only listen,
inputs send. Frames are JSON keyed by port, with json_key and on_connect.
fluksio.flow.connector_tls: trust the certificate a device presented on
first contact, kept in ConnectorNode.store, and name the new fingerprint
when another one is refused. Additive, so no contract version bump; hue
and wfrac use it.
The generated batch script exported nothing and passed `--token`, which
any user on a shared compute node reads from `ps`. It now exports
FLUKSIO_WORKER_TOKEN after `prerun`, which the worker already reads.
`ConnectorNode.store` keeps short strings per connector package in the
engine's database (`connector_state`, migration f8c3e5a91d27), so the nodes of
one package share them and `fluksio serve` needs nothing new: get, set and
delete, at most 64 kB a value and 256 keys a package. A superuser lists the
keys (never the values) and clears them through `/connectors/{node_type}/state`,
or under Stored state in a connector node's panel. Documented in the connector
contract.
DELETE /flows/%2e%2e reached FlowStore.delete_flow(".."), which removed
the data directory, and /flows/_lib removed every shared node. Every
path the flow and dashboard stores build from a flow, node, library or
dashboard name now goes through checked(), which raises InvalidName
(400) for anything _validate_name refuses. _validate_name uses
fullmatch, so a trailing newline is refused too.
Writing node source, installing modules and any flow save that adds,
retypes or repoints a code node (Function, Command), edits a Command
node's settings or changes a node's resources.env now answer 403 for
everyone but a superuser. MCP tools and the assistant reach the same
routes, so they inherit the gate. Node types report runs_code.
The editor shows code read-only with a note, disables a Command node's
settings, leaves code nodes and reusable nodes out of the palette and
paste, and the Modules page offers no install.
