Prefect Community

<@ULVA73B9P> can you link me to the sync engine entrypoint?

:white_check_mark: thought for 63.8 seconds

Assuming Prefect 3.x, here are the key sync engine entrypoints:

- Executable entrypoint (when a flow run is launched): <https://github.com/PrefectHQ/prefect/blob/main/src/prefect/engine.py|src/prefect/engine.py>
  - __main__ block: <https://github.com/PrefectHQ/prefect/blob/main/src/prefect/engine.py#L89-L124|engine.py (main)>
  - Signal handling: <https://github.com/PrefectHQ/prefect/blob/main/src/prefect/engine.py#L31-L86|handle_engine_signals()>

- Core sync engine and dispatcher: <https://github.com/PrefectHQ/prefect/blob/main/src/prefect/flow_engine.py|src/prefect/flow_engine.py>
  - Dispatcher: <https://github.com/PrefectHQ/prefect/blob/main/src/prefect/flow_engine.py#L1538-L1591|run_flow()>
  - Sync runner: <https://github.com/PrefectHQ/prefect/blob/main/src/prefect/flow_engine.py#L1406-L1427|run_flow_sync()>
  - Sync engine class: <https://github.com/PrefectHQ/prefect/blob/main/src/prefect/flow_engine.py#L242-L819|FlowRunEngine>
  - Subprocess entry (used by task runners): <https://github.com/PrefectHQ/prefect/blob/main/src/prefect/flow_engine.py#L1611-L1685|run_flow_in_subprocess()>
