Engine holds for a rename: the pipeline refuses publish and inline cascades with EngineHeld once those running have finished, the execution service stops claiming and its timers once claimed cascades have finished; both wait without a limit, report what is busy and can be aborted. REST answers 503 with Retry-After, a device frame busy. Redis adds no longer wait for each other, only a queue hold waits for them

__init__.py

Rename the import package app to fluksio

2026-08-21 21:48:05 +02:00

alert_ledger.py

Alerts: cooldowns survive a restart, and a connection must stay down a minute before it alerts

2026-10-28 12:46:42 +01:00

alerts.py

Rename orchestration, splice and routes: a Renamer runs one rename at a time, closing the gate, taking the controller lock and holding the engine, each waiting without a limit and saying what it waits for (summary rename status, rename_waiting); DELETE on the pending request or a closed connection calls it off until the journal begins (409 aborted); then journal, steps and audit, retried in the background on failure (503 completing); splice_renamed rebuilds the affected flows under the held lock keeping stopped, paused and parked work, history limits and device wiring refreshed before activation; AlertManager.rename and EventBus.rename/settle follow the names; flow and dashboard rename routes answer by code and repeat stored results; renamed, dashboard_changed and pipeline_rebuilt after release; fluksio serve reads flow files without building a FlowStore

2026-11-02 22:14:44 +01:00

artifacts.py

Camera permission and review fixes (openpanel C3, C4)

connector_store.py

Give connectors a store that survives restarts, and a way to clear it

2026-10-06 17:19:48 +02:00

connector_tls.py

Do not check a pinned certificate's dates

2026-10-07 10:11:08 +02:00

connector.py

connector: wanted(port) says whether anyone watches or reads a port

2026-10-27 15:20:24 +01:00

controller.py

pause_intake answers False when claimed work outlasts its timeout, and reload then resumes intake and raises RebuildBusy before tearing anything down

2026-11-05 06:43:33 +01:00

dashboards.py

A querying chart offers its own windows: an optional ranges list of {label, range_s, interval_s}, up to 8 and checked by the server, where range_s 0 asks for the whole history; the editor lists and picks them, and the refresh is capped at what a timer can hold

2026-11-06 14:33:25 +01:00

demand.py

connector: wanted(port) says whether anyone watches or reads a port

2026-10-27 15:20:24 +01:00

devices.py

History is kept by flow id: runs, cascades, rollups and events file the id in their flow column and nodes as <flow id>.<node>, the API answers flow plus flow_name and shows and takes nodes as <key>.<node>; events carry flow_id from the moment they are published; run queue items, the stage cache and cached curves keep ids and keys apart; endpoints, the brain graph, device bindings and search name the id to open

2026-11-02 19:01:19 +01:00

events.py

Rename orchestration, splice and routes: a Renamer runs one rename at a time, closing the gate, taking the controller lock and holding the engine, each waiting without a limit and saying what it waits for (summary rename status, rename_waiting); DELETE on the pending request or a closed connection calls it off until the journal begins (409 aborted); then journal, steps and audit, retried in the background on failure (503 completing); splice_renamed rebuilds the affected flows under the held lock keeping stopped, paused and parked work, history limits and device wiring refreshed before activation; AlertManager.rename and EventBus.rename/settle follow the names; flow and dashboard rename routes answer by code and repeat stored results; renamed, dashboard_changed and pipeline_rebuilt after release; fluksio serve reads flow files without building a FlowStore

2026-11-02 22:14:44 +01:00

executor.py

pause_intake answers False when claimed work outlasts its timeout, and reload then resumes intake and raises RebuildBusy before tearing anything down

2026-11-05 06:43:33 +01:00

identity.py

Rename journal, steps and recovery: rename.json (RENAME_JOURNAL_FILE) records each step, documents are written whole and committed alone (FlowStore.replace_documents, identity.write_documents) and rolled back before the journal goes forward; history per run scoped by flow id, alert ledger, alerts.json, state and queue steps idempotent and checkpointed; audit row once per op; recover_documents before assign_ids and recover_runtime before the engine is built, retried until done; repeated requests get the stored result, stale ones 409; plan refuses rename_in_progress; alerts.json written atomically; completeness scanner in the test utilities

live.py

Camera permission and review fixes (openpanel C3, C4)

2026-10-17 09:20:04 +02:00

logs.py

Test hygiene: forget the refused study, quiet _Tee on a closed stream, wait for connector recovery

2026-10-14 23:41:31 +02:00

messages.py

Backend messages and field descriptions that reach the UI lose their em-dashes

2026-10-27 17:52:55 +01:00

metrics.py

History is kept by flow id: runs, cascades, rollups and events file the id in their flow column and nodes as <flow id>.<node>, the API answers flow plus flow_name and shows and takes nodes as <key>.<node>; events carry flow_id from the moment they are published; run queue items, the stage cache and cached curves keep ids and keys apart; endpoints, the brain graph, device bindings and search name the id to open

2026-11-02 19:01:19 +01:00

modules.py

Modules resolve the manifest with uv pip compile before syncing, so listed packages bring their dependencies

2026-10-15 17:06:20 +02:00

namespace.py

Startup deletes the work queue's keys from before it moved from pipeline: to queue: (stream, timers, dead letters, parked lists, done markers), logged with what they held; an old stream still holding undelivered work stays, is logged as an error, and counts as queued work for the keys it names

2026-11-03 07:55:14 +01:00

pipeline.py

A batch run fails a node with no value on a triggering input instead of calling it, naming the input and its producer, and skips what waits on it

2026-11-05 07:35:02 +01:00

placement.py

SDK: artifacts work outside a node, run --follow prints status and queue waits, fluksio cancel

2026-10-28 08:07:35 +01:00

plugins.py

Rename the import package app to fluksio

2026-08-21 21:48:05 +02:00

provision.py

A node's worker label is worker, so a device is only a paired one

2026-10-16 16:56:05 +02:00

queue.py

Startup deletes the work queue's keys from before it moved from pipeline: to queue: (stream, timers, dead letters, parked lists, done markers), logged with what they held; an old stream still holding undelivered work stays, is logged as an error, and counts as queued work for the keys it names

2026-11-03 07:55:14 +01:00

remote.py

Service node: a server kept running on a worker (openpanel V2)

2026-10-19 18:43:04 +02:00

rename.py

Rename orchestration, splice and routes: a Renamer runs one rename at a time, closing the gate, taking the controller lock and holding the engine, each waiting without a limit and saying what it waits for (summary rename status, rename_waiting); DELETE on the pending request or a closed connection calls it off until the journal begins (409 aborted); then journal, steps and audit, retried in the background on failure (503 completing); splice_renamed rebuilds the affected flows under the held lock keeping stopped, paused and parked work, history limits and device wiring refreshed before activation; AlertManager.rename and EventBus.rename/settle follow the names; flow and dashboard rename routes answer by code and repeat stored results; renamed, dashboard_changed and pipeline_rebuilt after release; fluksio serve reads flow files without building a FlowStore

resources.py

Backend messages and field descriptions that reach the UI lose their em-dashes

2026-10-27 17:52:55 +01:00

runs.py

A batch run skips the nodes waiting on a failed one and ends error; a run whose nodes cannot load fails with the load error before anything executes; cancelling a run stops its pipeline without announcing a pause of the live flow; batch_issues refuses a delay node's interval; the client accepts an engine URL with or without /api/v1; RedisState's compare-and-swap records the names it writes

2026-11-04 21:38:21 +01:00

schemas.py

History is kept by flow id: runs, cascades, rollups and events file the id in their flow column and nodes as <flow id>.<node>, the API answers flow plus flow_name and shows and takes nodes as <key>.<node>; events carry flow_id from the moment they are published; run queue items, the stage cache and cached curves keep ids and keys apart; endpoints, the brain graph, device bindings and search name the id to open

secrets.py

Backend messages and field descriptions that reach the UI lose their em-dashes

2026-10-27 17:52:55 +01:00

state.py

RedisState's compare-and-swap watches through its pipeline, so a write between the compare and EXEC fails the swap; pause_intake waits out a claim already under way, so nothing dispatches after it returns

2026-11-04 21:53:41 +01:00

store.py

FlowNotFound says whether a published flow or any flow is missing; read_all stamps its cache with the revision from before its scan; dashboard discard and delete commits name the key; a RedisState ttl expires counters and the names set too; bench_startup publishes the version after its saves, and only when there is a draft
