AgentLab/backend/tests/test_run_options.py
ThearchyHelios 2e7d6103ea 应用库可移植到 PostgreSQL:AGENTLAB_DATABASE_URL 设成 postgresql+asyncpg://… 时整个应用库用 PostgreSQL,断点用官方的 langgraph-checkpoint-postgres(同一个库,AGENTLAB_CHECKPOINT_URL 可另给);不设时照旧是数据目录里的 SQLite,行为不变
- 配置:database_url、checkpoint_url(启动时校验写法,只认 PostgreSQL)、连接池四项;启动日志写用的是哪种库(主机、库名、用户,不写密码)
- 引擎(db/base.make_engine):SQLite 照旧 WAL、外键、忙等;PostgreSQL 用连接池、探活、会话时区 UTC,装上方言调整(db/postgres.py):建表时 String(n) 是不限长的 VARCHAR(SQLite 从不查长度,导过来的存量也可能超长)、ORDER BY 里可空列的 NULL 位置照 SQLite 补写(升序在前、降序在后,窗口函数里同样);Integer 列在 PostgreSQL 上是 BIGINT(列挂到表上时换成 with_variant,绑定参数跟着列按 BIGINT 转换);JSON 列两边都存原文(PostgreSQL 的 json,不用 JSONB:JSONB 重排对象里的键,快照的列序、表的先后读回来就变了);JSON 里的 NaN 写成 null、NUL 去掉(PostgreSQL 不收)
- 迁移按方言:已有的列和索引用 inspector 认;PostgreSQL 上补列的类型取模型里这一列的、缺省值取迁移表里的(布尔 0/1 换成 false/true),ADD COLUMN IF NOT EXISTS;去重语句里的布尔按方言写;部分唯一索引补 postgresql_where;init_db 在 PostgreSQL 上拿咨询锁(几个进程同时启动不撞)
- 应用库上的 SQLite 专用写法改成按方言编译的表达式(db/portable.py):json_extract 的十几处(口径召回、出具、对账、个人应用、幂等键、访问控制、数据源变化通知、剖析任务、待办超时)换成 json_eq / json_flag / json_text,json_type 换成 json_is_string(两种库同一套带类型的比较);能力登记的 sqlite insert 换成按会话方言的 insert_ignore;能力使用次数的 json_each 按方言分支;附件「没绑记录」的条件不靠 json 的等号;按报错文字认唯一约束的地方换成 unique_violation(按表和列认,两种库的报错都认得)
- 断点(engine/checkpoints.py):PostgreSQL 时开 psycopg 连接池、在咨询锁里 setup;runner 只认 BaseCheckpointSaver,读断点仍只走 saver 的公开接口
- 依赖:新 extra postgres(asyncpg、psycopg[binary] 3、psycopg-pool、langgraph-checkpoint-postgres 3.1.2);langgraph-checkpoint 卡在 <4.3(断点格式就在这个包里,postgres 包新版要 4.3,不动已装的 4.2.0);锁文件补上新包
- 运行收尾:记 action.unknown、安排核实做完才把运行摘掉(以前先摘掉,等「不在跑了」再读事件的一方在库慢时读不到这一条)
- 测试:AGENTLAB_TEST_DATABASE_URL 时跑在 PostgreSQL 上(每个 xdist 进程建自己的库、按事件循环分的连接池 tests/pgpool.py),不设时盖掉环境里的数据库地址照旧用 SQLite;scripts/test-postgres.sh 起临时的 postgres:16 容器跑全量;sqlite_only 标记;另开连接改库的几个竞态测试、触发器测试改成两种库都能跑(tests/appdb.py);新增 test_db_portable 守着方言调整、JSON 键序、超长字符串、大整数、NULL 排序、时区、PostgreSQL 老库迁移

"""运行选项和来源:Run.options 是发起时定下、整次运行沿用的选项快照,Run.schedule_id 是发起它的定时任务。
- 旧库升级时补这两列和 schedule_id 的索引;存量运行的选项读出来是 {},来源为空
- RunManager.start 收下两者并落库;选项非空时写进 run.started(进封存范围),为空时 run.started 和以前
逐字相同;恢复、继续运行沿用发起时的选项,节点从 RunContext.extra 读得到同一份
- 接口带出 schedule_id,运行列表能按定时任务筛;launch_run 原样往下交
