背景

#529 上一版把冲突相位的候选池按 sleepConflictMaxPairsPerRun(默认 60)分批,但一轮只送一批,剩下的对联要等满一个 sleepMinIntervalHours(默认 8h)才轮到。报告者那台库有 449 对,按 60/轮要 8 轮——等于把"分批"变成"隔夜慢慢分批"。

修改

本轮被预算截断、且送出去的每一对都落地了,就把下一次的冷却按 0 处理、只留一个静默窗口,让剩下的对接着追。

判据不能用 status === "ok":adjudicateBatch 的 status 是 applied > 0 ? (…) : failures.length ? "failed" : "noop",全判 keep 的轮次 applied 恒为 0、永远到不了 ok——而"判 keep 不落地"正是 #529 的核心症状,拿 status 当判据会在最该追的场景静默失效。

所以相位层另给一个正交布尔 clean(!interrupted && failedBatches === 0 && skipped.length === 0 && failures.length === 0 && conflicts.length === 0),runSleep 再把它和 perRunSkipped > 0 合成 catchup 交给调度器。

只改回调里的 if 不够,三处必须同时改:

  1. effectiveMinIntervalMs() 在续排时返回 0 —— shouldRun 与 armNextWindow 本来就读同一个函数,判定与排表口径天然一致;
  2. armIdleTimer / armNextWindow 的回调原本是 if (!ran) armNextWindow(),跑成了一轮就不重排。续排时库是安静的、没有下一次写入来救它,不改这一行续排只追一轮就断;
  3. 续排下限钉在一个 sleepIdleMinutes,否则冷却项归零后静默项可能已经是负的,算出来只剩那 1 秒,从"隔夜一轮"矫枉成"秒级连发"。

两道刹车:连续失败时不追(与退避互斥,两个逻辑抢同一只闹钟最容易空转);进程内连击上限 CATCHUP_STREAK_CAP = 24(全判 keep 的轮次不进任何"坏"分母,叠加续排会变成永不落地的每五分钟一轮,而审计上每轮都"有产出")。

刹车的落点收在 catchupWanted 这个状态上并同时清零连击——只写在 effectiveMinIntervalMs 里会让 armNextWindow 继续按静默窗口重排,每 5 分钟醒一次、被 shouldRun 否掉再重排,定时器链永不断且此后再也不真跑。

不新增配置键:续排下限直接用 sleepIdleMinutes,本轮的账本/更新写入会重置 lastWriteAt,天然节流。

测试

新增 test/sleep-catchup.test.js 8 条:

  • clean + backlog ⇒ 闹钟钉在静默窗口(5min + 1000ms)且真的起跑第二轮
  • 不 clean 时不追,间隔回到最小间隔
  • 失败轮不追(补的是退避长表而非续排短表)
  • 连追 24 轮到顶后不再补挂,也不空转定时器
  • 全判 keep 的轮次 applied=0 / status=noop / clean=true / catchup=true
  • 坏批让这一轮 clean=false,即使还有 backlog 也不追
  • 到顶收手后下一次正常触发能把连击从 0 重新算(不清零就成了永久闸)
  • 一轮抛错也要把连击清零(catch 路径)

变异自证六例全红:判据改成 status === "ok" → 2 红;回调不补挂 → 2 红;去掉连击刹车 → 1 红;clean 忽略 failures → 1 红;连击到顶只置 false 不清零 → 1 红;抛错不清零 → 1 红。恢复后 8/8 全绿。

全量 npm test:2617 tests / 2616 pass / 0 fail / 1 skipped。check-sync 通过(src ↔ lib 82 文件一致)。

已知未覆盖

Summary by CodeRabbit

  • 新功能
    • 睡眠任务在预算用尽且本轮处理完整、无失败或冲突时,可在一个静默窗口后自动继续处理待处理冲突,最多连续续跑 24 轮。
    • 处理未完成或出现失败时,不会快速续跑,并按原有退避机制重新安排任务;续跑期间有新写入时,将重新计算静默窗口。
  • 测试
    • 增加对续跑条件、失败退避、连续次数上限及计数重置的覆盖。

#529 上一版已经把候选池按 sleepConflictMaxPairsPerRun(默认 60)分批,但一轮只送一批,

Walkthrough

冲突阶段现在报告本轮是否 clean,以及是否仍有预算积压。调度器在满足条件时等待一个静默窗口后继续处理,并限制连续续排轮数。新增测试覆盖续排、失败退避、台账写入失败和恢复路径。

Changes: 睡眠任务续排

Layer / File(s) Summary
冲突阶段结果
dsh-mneme/lib/dream/sleep.js, dsh-mneme/src/dream/sleep.js
冲突阶段统计复核台账写入失败。只有未中断、没有失败批次、跳过项、失败项、CAS 冲突或台账写入失败时,clean 才为真。runSleep 返回 clean、backlog 和 catchup;只有本轮 clean 且存在 backlog 时,catchup 才为真。
续排调度与边界
dsh-mneme/lib/dream/sleep.js, dsh-mneme/src/dream/sleep.js, dsh-mneme/test/sleep-catchup.test.js, dsh-mneme/CHANGELOG.md
调度器在续排期间至少等待一个静默窗口,并在运行结束时从当前时刻重新计算窗口。连续失败时使用原有退避逻辑。连续续排最多 24 轮;失败、异常或不满足续排条件时清除续排状态。测试和变更记录覆盖续排条件、定时及恢复行为。

Review comments at @dsh-mneme/src/dream/sleep.js:
- Around line 685-686: 在 sleep 流程中汇总 saveConflictReviewed 的台账写入失败,并将该失败纳入 clean
判据;只要本轮有写入失败,就必须使 clean 和 catchup 为 false,阻止本轮续排。保留现有其他 clean 判定条件。
- Line 1105: 更新运行结束处对 armNextWindow 的调用逻辑:当续排结果要求继续运行时,即使 noteWrite 已挂载定时器,也要按
sleepIdleMinutes 重新计算并挂载定时器,避免沿用即将到期的旧定时器;同时确保 armNextWindow 的回调遵守相同的续排规则。

Review comments at @dsh-mneme/test/sleep-catchup.test.js:
- Line 172: 在连击上限测试和复位测试中,更新 h.setOutcome 桩,使其返回与真实 runSleep noop 路径一致的结果形状(ok 为
false),并调整断言以验证定时器恢复为正常冷却间隔,而非断言不存在定时器。

台账写入失败此前只进 logger.warn:那一对既没记成「已审」,又被算成「送出去的全
落地了」,下一轮原样回到候选池、又被算成可续排——每个静默窗口重问一次同一个冲突,
直到连击上限才停,而审计上每轮都是干净的成功轮。逐批把 ledgerFailed 报回
phaseConflicts,并进 clean 判据与审计行。

运行期间用户写入会走 noteWrite(),它按那一次写入重算闹钟、可能落在静默窗口的尾声。
收尾时 armNextWindow() 又被既存的 idleTimer 挡下,于是这一轮跑得久一点,下一批
就是「几秒后开跑」。改为 catchupWanted 为真时先撤旧表再从此刻重挂。

连击上限的用例桩原本写 ok:true,而 runSleep 在 status==="noop" 时给 ok:false,
测到的是桩的偏差而非实现的行为。改用真实形状,并断言收手后闹钟回到正常最小间隔。
