class cellmap_flow.dashboard.routes.logging_routes.LogHandler(level=NOTSET)

Feeds the log panel: each record, numbered, into the session’s log_buffer, and to every open stream’s queue.

It runs on whichever thread logged, often one with no app context (a launch, a job monitor), so it asks for the session at emit time.

emit(record)

Do whatever it takes to actually log the specified logging record.

This version is intended to be implemented by subclasses and so raises a NotImplementedError.

cellmap_flow.dashboard.routes.logging_routes.requested_offset(request)

Where a log stream’s client wants it from, in the dashboard’s log protocol (static/js/lib/sse.js): the SSE Last-Event-ID, else ?offset=.

cellmap_flow.dashboard.routes.logging_routes.stream_logs()

The log panel’s records as Server-Sent Events: those in the buffer after the one the client asks from (requested_offset; a reconnect asks from the last it was sent), then each new one as it is logged, with a keepalive comment every 30 s.

cellmap_flow.dashboard.routes.logging_routes.get_bbox_json_template()

Serve the bounding box JSON format template
