# Weave 执行决策与内部结果交付
|
||||
|
||||
状态：P4 内部基础已实现。已接通Pulse结果到Weave持久化Inbox，并提供有限步骤决策器；**实例启动、实例存储适配、Inbox消费推进、定时/信号运行器及对应公共SDK尚未实现**。不能把本页能力解释成流程已经可以端到端执行。
|
||||
|
||||
## 1. 为什么结果要独立持久化
|
||||
|
||||
任务已执行成功之后，流程节点可能立即退出。依赖进程内回调会丢失后继工作；从可变任务当前状态读取历史结果，也可能把后来的核查决定误当成旧事件。
|
||||
|
||||
当前结果事务顺序如下，任何一步失败均回滚：
|
||||
|
||||
```mermaid
|
||||
flowchart LR
|
||||
A[更新Pulse任务和尝试] --> B[结算执行许可与用量]
|
||||
B --> C[写入原始状态事件]
|
||||
C --> D[核验流程激活归属]
|
||||
D --> E[写入Weave Inbox和冻结快照]
|
||||
E --> F[锁定对外结果流并写入结果日志]
|
||||
F --> G[写入审计和执行回执]
|
||||
G --> H[提交事务]
|
||||
```
|
||||
|
||||
普通任务和计划任务仍使用原有结果链路，不产生Weave Inbox。流程任务使用`owner_kind=workflow_activation`、`owner_id=激活ID`；TASK直接关联激活task_id，POLL通过轮次记录关联。所有关系均限定同一命名空间，核对步骤、实例、门控、固定定义和版本，不使用外键。
|
||||
|
||||
已实现的内部交付触发为`task.succeeded`、`task.failed`、`task.cancelled`、`task.needs_review`。任务暂时失败并等待自动重试，不新增流程激活或内部结果事件。相同完成回执重报不产生第二个事件；同一来源任务状态版本还有独立唯一约束。
|
||||
|
||||
发布后使用旧激活的在途结果仍保留原激活身份；生产者不自行判定是否推进当前激活。未来消费者须识别旧激活/旧轮次并留痕，不能将其用于当前工作。
|
||||
|
||||
生产者在现有结果快照查询中一起读取所有者和关联标记；普通结果不增加一次单独网络查询。流程关联核验使用只读关联查询，不在已持有任务锁后再锁实例、步骤或对外订阅。内部Inbox写入发生在外部结果流行锁之前，保持既有锁顺序。
|
||||
|
||||
## 2. 数据模型与升级
|
||||
|
||||
迁移`000017_workflow_result_inbox`为`weave_inbox`新增四个中文注释字段：
|
||||
|
||||
| 字段 | 含义 |
|
||||
| --- | --- |
|
||||
| source_task_id | 来源Pulse任务 |
|
||||
| source_activation_id | 事件发生时的流程激活 |
|
||||
| source_revision | 来源任务的状态版本，大于零 |
|
||||
| snapshot | schema_version=1的独立结果JSON文本，最多512 KiB，保留原始数字精度 |
|
||||
|
||||
snapshot包含任务/队列ID、当时的状态与版本、结果、效果不确定标记和当前尝试ID；命名空间及实例由Inbox行固定。快照不依赖对外`orbit_result_events`的保留时间，也不从后来的任务结果重建。
|
||||
|
||||
`(namespace_id,event_id)`沿用原去重约束，新增`(namespace_id,source_task_id,source_revision)`唯一键。有效待处理记录必须四项完整且快照为合法JSON；只有迁移前的PROCESSED/QUARANTINED历史记录可以四项均为空。没有外键或级联。
|
||||
|
||||
v16及以前的未处理记录缺少冻结来源，升级后统一标为QUARANTINED，原租约清空、代次保留，error_code为LEGACY_RESULT_UNVERIFIED；已处理历史保持原状态。迁移不使用当前任务倒推旧结果，不赋予旧记录新的执行权。
|
||||
|
||||
新字段对应`weave/model/InboxEvent`，Go与SQL均有中文注释。原有扫描索引`(state,available_at,namespace_id,id)`保留，后续消费仍按持久化待处理状态和有限批次驱动。
|
||||
|
||||
关联丢失或类型异常时拒绝提交权威任务结果，不能悄悄丢掉内部交付后返回成功。此类持续异常需要修复存储关系后原身份核对；本阶段尚未提供自动修复工具。
|
||||
|
||||
## 3. 纯步骤决策器
|
||||
|
||||
`weave/engine.Compile`校验并独立拷贝已发布的结构版本1定义。Program可并发读取，调用方修改原定义或取出的步骤副本不会改变它。
|
||||
|
||||
`Program.Plan(snapshot, limit)`接受事务内读取、已校验归属的当前步骤快照，返回最多1–32个ACTIVATE、COMPLETE或SKIP决策。它不执行HTTP、业务Go函数、数据库写入，也不读取当前时间。绝对截止、许可与执行授权继续由存储及Pulse负责。
|
||||
|
||||
| 能力 | 已实现的决策行为 |
|
||||
| --- | --- |
|
||||
| 顺序 | 仅消费已成功步骤输出；后继不会提前读取结果 |
|
||||
| 分支 | 首次按条件选择，保存case索引；再次推进复用选择，未选择路径分批标为SKIPPED |
|
||||
| 并行 | 分支分别使用进入节点前的数据，全部完成才产生组合输出；兄弟结果通过命名汇合读取 |
|
||||
| TASK | 解析输入与追踪/资源键，按Pulse运行数据边界检查；返回待持久化任务参数，不授予执行权 |
|
||||
| SIGNAL | 解析并冻结非空业务关联、名称与参数版本，返回等待命令 |
|
||||
| TIMER | 返回持久化等待命令，不分配业务Worker |
|
||||
| POLL | 解析固定查询输入及可选回执关联；成功查询结果有独立分类器，PENDING不等于节点成功 |
|
||||
| 暂停门控 | AllowNew=false时不激活新业务工作，允许整理已有组合结果；不替代数据库门控校验 |
|
||||
| 有限推进 | More=true时说明本轮变更预算耗尽，必须由适配层保存待续记录；已有活动分支仍继续校验，不能仅安排内存回调 |
|
||||
|
||||
只在已保存的SUCCEEDED投影上读取输出；类型不匹配、未知/失败状态、不可达的执行、已完成组合下仍有未结清子节点、伪造组合输出等都会拒绝整轮决策。不返回可以部分应用的错误结果。
|
||||
|
||||
引用与对象/数组构造保留JSON原始数值，输出及累计构造有大小上限；数字条件使用精确有理数比较。相邻大整数、长小数和科学计数法不会先转成float64。规则不提供任意脚本、动态时间或随机数据。
|
||||
|
||||
`ClassifyPoll`仅处理“查询请求成功”的业务结果，返回PENDING、SUCCEEDED、FAILED或NEEDS_REVIEW；未知值/类型错误拒绝。即使快照将POLL标为SUCCEEDED，结果仍在处理中、失败或待核查时也不能推进后继。
|
||||
|
||||
## 4. 后续存储适配必须满足的条件
|
||||
|
||||
此处是尚待实现的要求，不能按纯单测宣称已完成：
|
||||
|
||||
1. 启动时认证、固定不可变版本/输入和策略、校验全部队列、计算实例截止，并在同事务创建实例、门控、首批激活/任务及审计回执。相同身份返回原实例。
|
||||
2. 消费者领取内部事件后核对命名空间、来源任务版本、激活/轮次及当前步骤版本；消费确认、步骤变化、后续任务或持久化待续记录同事务提交。
|
||||
3. Plan返回值只有存储事务提交后才生效。额度不足或事务失败不能留下孤立激活/许可；重启从持久化快照重新计算，不重复创建已有任务。
|
||||
4. AllowNew来自权威实例状态、控制版本、取消、总截止和门控。程序参数本身不是权限证明。任务deadline不得超过实例或查询节点绝对截止。
|
||||
5. 数据库时间驱动真实等待与超时，按可靠受理时间裁决信号/结果，原截止和预算在恢复时保持。单轮重试与查询轮次不能互相补充次数。
|
||||
6. 完成实例前核对所有活动工作结清和未知效果；失败/取消需要停止新派发并收集在途结果。人工恢复通过新激活保留历史。
|
||||
7. 增加流程来源查询、实例/步骤/信号/操作HTTP和独立SDK、可运行端到端场景、真实节点强杀和竞争回归。以上均属于P4–P5剩余工作。
|
||||
|
||||
当前测试夹具通过SQL构造流程关联，只验证结果事务边界；它不代表公共实例API或运行器已经存在。纯决策器的JSON往返测试验证可从快照重算，也不等同于真实进程恢复验收。

# P4 进展：步骤决策与内部结果交付
|
||||
|
||||
日期：2026-09-18。本次完成纯步骤决策器、Pulse结果原子写入Weave Inbox及独立快照迁移；P4整体尚未完成，实例API、消费推进与真实等待运行器仍待开发。设计与边界见[内部基础](../10-workflow-engine-core.md)。
|
||||
|
||||
## 代码与数据变化
|
||||
|
||||
- weave/engine提供不可变编译结果、1–32变更预算的顺序/分支/并行决策、任务参数与等待描述、精确数字条件及POLL业务状态分类。不会调用业务处理器或授予执行权。
|
||||
- 结果事务复用现有任务快照查询读取关联；内部交付先于对外结果流行锁，任务/尝试/许可/原事件/内部快照/外部日志/审计/回执一起提交或回滚。
|
||||
- 新迁移000017为Inbox增加来源任务、激活、状态版本和独立快照4字段，全部中文注释。35个实体、293个直接声明持久化字段，零外键/级联。旧的未验证记录隔离，不按当前任务重建历史。
|
||||
- 尚无新的公共运行API或SDK；已有定义发布SDK和其余场景随完整回归验证，执行器不作为业务端可调用的SDK暴露。
|
||||
|
||||
## 已完成验证

|

|

make integration
|
||||
```
|
||||
|
||||
本次实际通过GO参数选择Go 1.27.1、DOCKER参数选择本机Docker；脚本自行创建隔离数据库，不连接已有业务数据库。数据库环境变量缺失时普通单测会跳过集成用例，不能代替上述真实integration结果。
|
||||
|
||||
测试中的流程关联由受控SQL夹具创建，不能作为实例受理实现的证据。数据库写入失败通过触发器注入，之后原完成身份重报成功；没有修改接口约束以接受不合法回执。
|
||||
|
||||
首次完整回归暴露两处旧升级测试未适配v17：v9还原夹具遗漏删除新增Inbox字段，v7索引保留比较未单独核验新增唯一索引。已修正夹具并增加该唯一索引列序/唯一性断言，重跑存储全量通过；没有修改历史迁移或放宽零外键检查。
|
||||
|
||||
复查另发现决策器在左侧分支耗尽变更预算后，提前返回另一个已有分支，误报其活动子任务不可达。新增测试先复现，再将预算限制保留在新增变更处，继续遍历已有选中路径；恢复后各任务仍只激活一次，最终输出及完整race检查通过。
|
||||
|
||||
## 尚未实现及后续工作
|
||||
|
||||
下一步实现实例存储适配与Start/Get/步骤查询：认证、固定版本/输入、实例及门控、首批任务与幂等/审计同事务；之后内部事件消费、有限推进检查点、持久化等待、流程来源与SDK接入。POLL轮次、信号竞争、暂停/取消/核查恢复与预算维护继续按P4–P5交付。
|
||||
|
||||
本阶段没有真实流程进程重启回归、持久化轮询或信号/定时消费器。P3已有进程故障测试只证明原任务和订阅链路，不能替代Weave运行器验证。增加关联索引读取与快照写入后的吞吐、存储增长、清理及跨版本上线边界继续在P6–P7验证，不声称生产容量和高可用已达标。
