fix(PipelineRunner): 接力棒断链修复 + 依赖级联自动唤醒引擎
This commit is contained in:
@ -5,18 +5,37 @@ PipelineRunner:基于 StepSpec 声明式调度 14 个 step。
|
||||
设计要点:
|
||||
- StepSpec 声明 requires(ctx 字段名列表)+ produces(ctx 字段名列表)
|
||||
- 命名约定:ctx 字段名 == panel key 名 == step 形参名(全链路无翻译)
|
||||
- 保留 spec.parameter_map 字段骨架供极少数特例覆盖(默认空 dict)
|
||||
- 步骤命名:step_id 格式为 stepN 或 stepN_suffix(无小数位),method_name 与 step_id 对齐
|
||||
- 调度顺序:按 PIPELINE_STEPS 列表顺序,requires 缺则 skip
|
||||
- 软取消:在每个 step 前检查 ctx.is_cancelled()
|
||||
- 断点续跑:spec.output_file 已落盘则跳过执行
|
||||
- 错误汇总:全流程结束后 error_summary 记录所有 step 的异常
|
||||
- 预检:run() 入口硬校验 step1 img_path;其余依赖通过智能补全 + 软警告处理
|
||||
- PipelineHalt:外层 run() 不 catch,触发循环 break,实现硬终止
|
||||
- STEP_MAP:旧 step_id → 新 step_id 双向映射,供 GUI 配置兼容使用
|
||||
- duck-typed pipeline:runner 只调 getattr(pipeline, method_name),不强依赖类层级
