Aleix Conchillo Flaqué	d07ba562eb	Separate bus messages from pipeline frames ... BusMessage was a mixin tacked onto DataFrame / SystemFrame so the bus could reuse the frame priority machinery. That made every bus message also a Frame, which is misleading — bus messages travel on the bus, not through pipelines. If a worker actually needs to ship a frame, it wraps it in BusFrameMessage. BusMessage is now a plain dataclass base carrying source/target. BusDataMessage and BusSystemMessage are empty subclasses that exist only as priority markers. The bus router and the priority queue check ``isinstance(item, BusSystemMessage)`` directly instead of ``isinstance(item, SystemFrame)``. The serializer test that round-tripped DataFrame.name (a non-init field) is rewritten against a local _MessageWithNonInit(BusDataMessage) subclass so the serializer's init=False path stays covered.	2026-05-21 19:07:13 -07:00
Aleix Conchillo Flaqué	b03247f360	Rename BaseTask → BaseWorker and reserve "task" for asyncio ... Replaces every "task" identifier that referred to the BaseTask abstraction with "worker". Asyncio task plumbing (asyncio.Task, BaseTaskManager, TaskManager, create_task, cancel_task, etc.) stays untouched. Highlights: - Classes: BaseTask → BaseWorker, PipelineTask → PipelineWorker, LLMTask → LLMWorker, LLMContextTask → LLMContextWorker, TaskBus → WorkerBus, TaskRegistry → WorkerRegistry, TaskActivationArgs → WorkerActivationArgs, TaskReadyData → WorkerReadyData, TaskRegistryEntry → WorkerRegistryEntry, TaskObserver → WorkerObserver, all Bus*TaskMessage → Bus*WorkerMessage, BusAddTaskMessage.task field → worker, BusWorkerRegistryMessage.tasks field → workers. - Methods/decorators: activate_task → activate_worker, deactivate_task → deactivate_worker, add_task → add_worker, watch_task → watch_worker, @task_ready → @worker_ready, setup_pipeline_task hook → setup_pipeline_worker. - Params/fields: FrameProcessorSetup.pipeline_task and FunctionCallParams.pipeline_task → pipeline_worker. Parameter names like task_name → worker_name; spawn/run accept worker:. - Files: pipeline/base_task.py → base_worker.py, pipeline/task.py → worker.py (plus a re-export shim at pipeline/task.py), task_observer.py → worker_observer.py, task_ready_decorator.py → worker_ready_decorator.py, pipecat.tasks → pipecat.workers, llm_task.py → llm_worker.py, llm_context_task.py → llm_context_worker.py, examples/multi-task → examples/multi-worker. Back-compat: - PipelineTask kept as a deprecated subclass of PipelineWorker that warns on construction. - pipecat.pipeline.task re-exports PipelineWorker/PipelineTask/etc. so existing user imports keep working. - FrameProcessor.pipeline_task kept as a deprecated property that forwards to pipeline_worker. Local variables in examples that hold a worker (task = PipelineTask(...)) are renamed to worker = PipelineWorker(...). Asyncio-task locals (runner_task, etc.) are preserved.	2026-05-21 19:07:13 -07:00
Aleix Conchillo Flaqué	402cf8dade	Port multi-task unit tests from pipecat-subagents ... Brings over 215 tests across 15 files covering the new multi-task framework: BaseTask / PipelineTask bus lifecycle, job RPC and job groups, the bus message hierarchy and serializers, TaskBus + AsyncQueueBus + RedisBus + PgmqBus (with direct and isolated backends), TaskRegistry, the BusBridgeProcessor, the WebSocket proxy tasks, the LLMTask deferral logic, and the PipelineRunner spawn-and-attach flow.	2026-05-21 10:13:21 -07:00
