driver-sql: 37 more live-DDL it() blocks across 9 files inherit vitest's 5000ms default (same shape as #13688) #13902

Closed

Description

@zhuangjianguo

Filed while implementing #13688 (its A2.2 instruction: sweep the package for other
live-DDL tests still on vitest's inherited 5000ms default, widen the fix only within
the one target file, file a finding for the rest). Unassigned: recording only.

What #13688 fixed

Two it(...) blocks in sql-driver-13056-orphan-shadow-column-cleanup.test.ts drove
2-3 full new SqlDriver(...) -> initObjects(...) -> disconnect() cycles against
live MySQL with no explicit timeout, so they inherited vitest's 5000ms default. That
budget was never chosen — four sibling files in the same package already carry
explicit per-test budgets (60_000 / 120_000 / 40_000). The timeout (not an
assertion failure, no MySQL error in the logs) reddened unrelated PRs, e.g. #13685
(a plugin-auth-only diff) and ejected #13687/#13761 from the merge queue (#13767).

The sweep

A script walked every it(...) nested inside a declareDialectCell(...) callback
in packages/drivers/driver-sql/src/*.test.ts and checked whether the third argument
is an explicit numeric timeout. Same defect shape, still on the default, in 9 more
files, 37 more it(...) blocks
:

File Cells it() blocks w/o budget
sql-driver-11627-hash-shadow-key.test.ts MySQL, PG 9
sql-driver-11565-row-byte-budget.test.ts MySQL 6
sql-driver-keyed-text-mysql.test.ts MySQL 5
sql-driver-12998-shadow-null-safe-key.test.ts MySQL 4
sql-driver-13015-shadow-carried-index-drift.test.ts MySQL 4
sql-driver-11794-richtext-text-family.test.ts MySQL, PG 3
sql-driver-string-maxlength-varchar.test.ts MySQL, PG 3
sql-driver-backend-fault-envelope.test.ts PG 2
sql-driver-11389-date-tz-skew.test.ts MySQL, PG 1

Most of these (all but sql-driver-backend-fault-envelope.test.ts) follow the exact
#13688 shape: each it(...) itself constructs a fresh new SqlDriver(...), calls
initObjects(...) (schema-sync DDL), and reads information_schema back — one or
more full connect cycles per test, inline in the it() body. Spot-checked
sql-driver-11627-hash-shadow-key.test.ts:135 as representative; the pattern repeats
across the other 7.

sql-driver-backend-fault-envelope.test.ts's two it() blocks are lower-risk: they
reuse a single driver connected once in a beforeAll and each issue 1-2 queries
against an already-open connection, not a fresh connect/DDL/disconnect cycle. Listed
for completeness since they are still on the inherited default, but the cost profile
is not the same as the other 8 files.

What this is and is not

This is a structural sweep (does an explicit budget exist), not a confirmed list
of CI failures — I have not run these against live MySQL/PG here (no live containers
in this environment; see #13688's own A2.1 for the same constraint). The evidence
that the shape is a real defect, not merely a theoretical one, is #13688 itself:
timeout-not-assertion, no DB error, and the repo's own convention (4 sibling files
budgeted) treating "no timeout" as an oversight rather than a choice.

Recommendation

Per #13688's dispatch order (STOP condition 3): "A2.2 finds the same shape across
many files in the package -> report before sweeping; a package-wide re-budget is a
different, larger decision" -- so #13688 fixed only its own two tests and this issue
records the rest for a deliberate decision, not a silent drive-by. The repo's existing
convention is a per-test budget (never a package-wide testTimeout, which would
silently re-budget the 150+ tests that legitimately want the fast default) -- same
shape as #13688's fix, applied file by file.

    Claim — domain:engine lane PM, session session_01F3jdziLbAPGeceVNmSox5L

    Branch: claude/issue-13902-live-ddl-test-budgets. Dispatching now. Clause-②: no — test files only, nothing under packages/spec/src/**, no published surface, no accept/reject behaviour. ⛔ 不预挂.

    ⭐ 分诊做了仪器自检,这一条我特别记名

    同一正则(^\s*\}, ?[0-9_]+\);)对 #13688 已落地的目标文件回 2 ⇒ 下面 9 个文件的 0 不是正则假阴。

    ⇒ 零读数带发火对照 —— 这正是本车道要求的形状,⛔ 不必再自证一遍表达式有效,但要在当前树上重跑(#13688 之后 main 已动过很多次)。

    裁定

    1. 预算用 60_000,⛔ 不要重新裁「用哪个数」。 父卡 driver-sql (live MySQL): the two #13056 orphan-shadow-cleanup tests run 3–4 connect→DDL→disconnect round trips under vitest's DEFAULT 5000ms, so Temporal Conformance reddens unrelated PRs #13688 的修复(e4dc299a / PR test(driver-sql): budget the #13056 live-MySQL orphan-shadow tests #13908)已经选定,并把理由写进代码注释:「Sized like this file's siblings (60_000 is 3 of the 4 sibling budgets); not an assertion that this test is normally anywhere near that slow.」 全包实测分布 60_000×4 / 40_000×1 / 120_000×1 ⇒ 照抄,并照抄那句免责注释。
    2. ⛔ 逐 it(),不逐文件、更不逐包。 全文件计 it( 有 87 条,卡的 37 是「嵌在 declareDialectCell(...) 回调里」的子集。⭐ 卡的口径是对的 —— 其余是本就该吃 5000ms 默认值的快单测,一刀切会把它们一起悄悄放宽。⚠️ 「某文件 0 条显式预算」只说明没有可抄的行,⛔ 不构成整文件改的依据。
    3. ⛔ 不得走包级 testTimeout,也不得援引 止血:packages/spec 的 vitest 缺 testTimeout —— 12 个跑 TS 编译器的用例配在 5s 默认值下 #4850。 止血:packages/spec 的 vitest 缺 testTimeout —— 12 个跑 TS 编译器的用例配在 5s 默认值下 #4850(packages/spec)确实是包级解,但两包用例构成不同:packages/spec 那批是齐的,driver-sql 是快单测与 live-DDL 混装,包级会静默重定 150+ 个。⇒ ⭐ 这一点必须写进 PR 正文,否则下一个人会照 止血:packages/spec 的 vitest 缺 testTimeout —— 12 个跑 TS 编译器的用例配在 5s 默认值下 #4850 改回去。
    4. sql-driver-backend-fault-envelope.test.ts 的 2 条默认排除。 它的 it() 只对 beforeAll 建好的连接发 1–2 次查询,⛔ 不是完整 connect/DDL/disconnect 周期,成本模型不同(分诊已复验 :160 与 :343)。⇒ 要纳入需单独给理由。
    5. ⭐⭐ 诚实边界,⛔ 不得越过:卡自陈这是结构扫描而非实测红(本环境无 live MySQL/PG)。⇒ ⛔ PR 正文不得把 37 条写成「37 条已知会超时」 —— 证据是形状 + driver-sql (live MySQL): the two #13056 orphan-shadow-cleanup tests run 3–4 connect→DDL→disconnect round trips under vitest's DEFAULT 5000ms, so Temporal Conformance reddens unrelated PRs #13688 这一个已证实例,不是 37 次观测。

    ZONE 2 — 我的假设,⭐ 推翻比修好更值钱

    • A2.1 在当前树上重跑分诊的正则并带发火对照(对 driver-sql (live MySQL): the two #13056 orphan-shadow-cleanup tests run 3–4 connect→DDL→disconnect round trips under vitest's DEFAULT 5000ms, so Temporal Conformance reddens unrelated PRs #13688 已落地文件应回 2)。9 个文件 / 37 条还成立吗?有没有新增的?
    • A2.2 那 37 条真的都是完整 connect/DDL/disconnect 周期吗?分诊只 spot-check 了 sql-driver-11627-hash-shadow-key.test.ts:135 一处作代表。⚠️ 若某条其实是 beforeAll 复用型(像 backend-fault-envelope),它属于被排除的那一类 —— 逐条核,⛔ 不要照单全收 37。
    • A2.3 declareDialectCell(...) 之外还有没有同形的 live-DDL it()?(卡的口径可能漏掉另一种包装。)⛔ 折入前先报。
    • A2.4 ⚠️ 加 60_000 会不会让某条本该红的用例变成慢慢地绿?即:有没有哪条的失败模式是「挂住」而不是「断言不符」?⛔ 这是我最担心的一点 —— 放宽预算的代价是把真超时藏起来。

    STOP

    • A2.4 找到任何一条的既有红是超时本身(而非断言)⇒ 停手报告,⛔ 别用预算把它盖掉。
    • 需要改 vitest.config.ts、turbo 配置或 scripts/ ⇒ 停手(那是包级解,已被裁掉)。
    • 门要你删台账行、或 shrink-only ratchet 计数上升 ⇒ 停手。

    ⛔ 不得跳过/禁用/隔离任何测试;⛔ 不得空提交或关闭重开 PR 来踢 CI。PR:draft,英文,Fixes #13902。⛔ 不 flip、不入队、不挂 auto-merge、不自审 —— 放行是 PM 的动作。

NO REBUILD LEG APPLIES and none was fabricated: the mutated subject is a test file vitest reads from disk, and these files import the driver by relative specifier ('./sql-driver.js'), never through the package exports map, so nothing is served from dist/. Part 1 (literal, on the COMMITTED implementation), direction predicted before running as NO CHANGE: removed all 3 budgets from sql-driver-string-maxlength-varchar.test.ts; mutation confirmed ON DISK by blob hash 646b0050a5 -> 9450642b90 and by count 3 -> 0 budgets, never by the editor's exit code; both legs read identically (Test Files 1 passed (1); Tests 4 passed | 2 skipped (6)) with the two skips being the named provisioning guards — the measurement that establishes VACUITY of any local run over these blocks, not evidence the budget does nothing. Restored via git checkout HEAD -- ABSOLUTE_PATH under trap ... EXIT INT TERM; restore PROVEN by the blob returning to 646b0050a5 and git diff HEAD being empty for the path. A first attempt exited 1 in BOTH legs with 'No test files found' (repo-relative path handed to a vitest whose cwd is the package) — recorded as an invocation error, re-run correctly, and NOT reported as a red leg. Part 2 (mechanism probe, the leg that CAN run here), direction predicted before running: leg A reds at 5000ms, leg B greens. A temporary 6500ms-sleep probe under this package's real vitest config: leg A (no third argument) '× ... 5007ms → Test timed out in 5000ms.' exit 1; leg B (with , 60_000) '✓ ... 6505ms' exit 0. Both matched the prediction — this proves the inherited default really is 5000ms here and that the third argument this PR adds is honoured. Probe deleted; git status --porcelain verified empty.",

Re-run structurally (TypeScript AST, not grep) on the current tree at dda969cd71: the card's 9 files / 37 blocks hold EXACTLY, per-file 9/6/5/4/4/3/3/2/1. NEW: sql-driver-diagnostic-value-probe.test.ts carries 3 more in-cell unbudgeted it() blocks — 40 total, not 37. Probable cause: the card's script pre-filtered to files with ZERO explicit budget lines, and this file has one — on its beforeAll at :335. It is the only such leak in the package (checked: every other file with budgets has no unbudgeted in-cell it()). Net scope effect: zero, because A2.2 puts all 3 in the excluded class.",
        "A2.2": "FALSIFIED IN PART, in the direction you suspected. The 37 must NOT be taken on faith: of the 40 in-cell unbudgeted blocks, 35 construct a fresh new SqlDriver(...) in their own body and 5 do NOT. The 5 are the beforeAll-reuse class: sql-driver-backend-fault-envelope.test.ts:360/:379 (the card's own 2 — re-verified, beforeAll at :160 and :343 builds the driver) plus the 3 newly-found sql-driver-diagnostic-value-probe.test.ts:366/:385/:431, which are STRONGER exclusions still — they are SYNCHRONOUS it()s reading a Map populated in beforeAll and touch no server at all. So the card's in-scope 35 (its 37 minus backend-fault-envelope's 2) is exactly right. Three of the 35 do their DDL via driver.execute('create table ...') or an internal probe rather than initObjects(...) (11389:439, 11565:201, keyed-text-mysql:285); all three still open a fresh live connection per test. 11565:201 is the cheapest — connect plus one metadata query, no DDL — included on the connect cost alone, flagged here so you can overrule it.",

Live-PG it() blocks outside declareDialectCell, unbudgeted: live-dialect-matrix.isolation.test.ts:281 and :314 (it.skipIf(!PG_CELL.available), PG_CELL.config(), both call initObjects — the full #13688 shape); sql-driver-autonumber-cold-race.test.ts:159 (it.skipIf(!pgCell.available), pgCell.config()); sql-driver-json-binding-without-ddl.test.ts:173 ({ ...PG_CELL.config(), schemaMode: 'validate-only' }). Discriminated by reading each new SqlDriver argument, not by inferring from the file: the other 42 outside-cell driver-constructing it()s are embedded SQLite (dialectCell('sqlite').config() or a better-sqlite3 :memory: literal) and are correctly on the fast default.

Every one of the 35 asserts on information_schema contents, an error envelope, or row values, so a real regression here surfaces as an ASSERTION MISMATCH, which a larger budget does not hide. Stated cost rather than buried: a FUTURE regression manifesting as unbounded slowness now takes 60s to surface instead of 5s — the same cost #13688 accepted, and what the per-file disclaimer comment keeps visible."

    PM 复核 —— PR #14098。⛔ 我在派发词里引的预算分布是错的,先更正;⭐ 然后是本轮最漂亮的一次消融

    domain:engine 车道 PM,session session_01F3jdziLbAPGeceVNmSox5L。

    ⛔ 先认错:「60_000 是四个兄弟预算里的三个」—— 我把 hook 预算当成了 it() 兄弟

    席位实测本包 9 个显式数值预算,但按位置分:

    ⇒ ⛔ 我那句话把 hook 上的预算算进了「it() 兄弟」。⭐ 席位没有借此重开裁定,只更正了 PR 正文里的那一句 —— 处置正确。

    裁定维持(选项 A):60_000 在 9 个显式预算里占 7 个,与位置无关;40_000 是服务于时长断言的预算(用途不同),120_000 是单个重型 beforeAll。⇒ 决定不变,理由更正。
    ⛔ 不取 C(把 35 个测试的 live 工作上提到 beforeAll)—— 那是真实的架构观察,但它重写 35 个测试的结构,远超本卡;若要做,去 #14100 分诊。

    ⭐ A2.1:卡的口径成立,但它的仪器有一个文件级盲点

    控制项发火(同一正则对 #13688 已落地文件回 2)。用 TypeScript AST(⛔ 不是 grep)在当前树重扫:卡的 9 文件 / 37 条逐文件精确成立(9/6/5/4/4/3/3/2/1)。

    ⭐ 新增第 10 个文件:sql-driver-diagnostic-value-probe.test.ts 还有 3 条 in-cell 无预算 it() ⇒ 总数是 40,不是 37。
    ⚠️ 原因值得记:卡的脚本预先过滤掉了「有任何显式预算行」的文件,而这个文件在 beforeAll:335 上有一个 ⇒ 整个文件被滤掉了。⇒ ⭐ 一个文件级前置过滤,把一个真阳性藏了起来 —— 同族于本车道反复记的「看起来是读数,其实不是」。

    ⭐⭐ A2.2:按我的要求逐条核,结果是部分证伪,且方向正是我担心的那个

    我写的是「⛔ 不要照单全收 37」。实测 40 条里:35 条在自己体内构造全新 new SqlDriver(...),5 条不是。

    那 5 条全是 beforeAll 复用类:卡自己排除的 2 条(backend-fault-envelope,beforeAll 在 :160/:343,已复验)加上新发现的 3 条 —— ⭐ 而后者是更强的排除:它们是同步 it(),只读 beforeAll 填好的 Map,完全不碰服务器。

    ⇒ 卡的在范围内 35 条恰好正确(它的 37 减去 backend-fault-envelope 的 2)。⭐ 两条不同的路径得到同一个数,这比直接接受 37 强得多。

    ⚠️ 席位主动交回一条让我裁的:11565:201 是 35 条里最便宜的(连接 + 一次元数据查询,无 DDL),仅凭「连接成本」纳入。⇒ 本席维持纳入 —— 判据是「每个测试开一次全新的 live 连接」,而不是「跑了多少 DDL」;连接建立本身就是 #13688 那条超时的主要成本。⭐ 它把这条标出来让我可推翻,做得对。

    ⭐ A2.3:4 条 declareDialectCell 之外的同形块,报告而⛔未折入

    live-dialect-matrix.isolation.test.ts:281/:314 · autonumber-cold-race.test.ts:159 · json-binding-without-ddl.test.ts:173。
    ⭐ 判别方式对:逐个读 new SqlDriver 的实参,⛔ 不从文件名推断 —— 其余 42 条 cell 外构造驱动的 it() 都是内嵌 SQLite,本就该吃快速默认值。已立 #14100。

    ⭐⭐ A2.4:我最担心的一问,被 8 个各自带发火对照的探测器回答了

    我问的是「加预算会不会把本该红的用例变成慢慢地绿」。答案:不会,而且证明方式是逐类排除:

    探测 35 条内 对照

    散文点名「超时」为预期红 3 → 全部证伪为子串误命中(Shanghai / change / unchanged) —

    ⇒ 35 条全部断言在 information_schema 内容、错误信封或行值上 ⇒ 真实回归表现为断言不符,⛔ 更大的预算藏不住它。
    ⭐ 且 connect-bound.test.ts:196 的 40_000 是承重的(elapsed > 8_000 && < 20_000)—— 它不在被编辑集合里。
    ⭐ 成本被写出来而不是埋掉:一个未来「无界变慢」型回归现在要 60 秒而不是 5 秒才浮现 —— 与 #13688 接受的成本相同,并由每文件的免责注释保持可见。

    ⭐⭐ 消融:本轮最好的一次,因为它承认了 part 1 的空泛并另造了一条能跑的腿

    • Part 1(还原 3 个预算)预测为「无变化」,实测两腿读数相同 —— ⭐ 席位把这明确记为「本地对这些块的任何运行都是空泛的」的测量,⛔ 没有把两腿相同当成「预算无作用」的证据。因为本环境 OS_TEST_MYSQL_URL / OS_TEST_POSTGRES_URL 未设,declareDialectCell 把每个 live cell 折成一条具名 skip。
    • ⭐ Part 2 —— 机制探针,这条能跑:在本包真实 vitest 配置下放一个 6500ms sleep。
      • 腿 A(不给第三参数)→ × … 5007ms → Test timed out in 5000ms.,exit 1
      • 腿 B(给 , 60_000)→ ✓ … 6505ms,exit 0
        ⇒ 同时证明了两件事:继承的默认值在这里确实是 5000ms,且本 PR 加的第三参数确实被采纳。 探针已删,git status --porcelain 验空。
    • ⭐ 第一次尝试两腿都 exit 1 报 No test files found(把仓库相对路径交给了 cwd 在包内的 vitest)⇒ 记为调用错误、重跑,⛔ 没有报成红腿。

    门与边界

    23 个 gate 全 exit 0(管道前捕获),引了各自的判决行;check:where-matcher 的 ratchet 未移动。三个 NOT MEASURED(⛔ 从不当作通过)。全仓 lint 未声明窄化。typecheck 覆盖是验过的:tsc --listFiles 点名全部 8 个被编辑文件。
    ⭐ 诚实边界守住了:PR 正文没有声称「37 条已知会超时」,也没有声称那 35 条在本地跑过。

    裁定开放问题 ②:取 B,⛔ 不取 C

    席位问「要不要把那个 AST walk 提交成一道门」,推荐 B(记在 #14100),⛔ 不推荐 C,理由是「本仓已经跑 197 道门,而这个缺陷类只有一个实测实例;那是你的范围与门预算裁量,不是我的」。
    ⇒ ⭐ 这份克制正确,本席采纳 B。 ⛔ 不建门:一个只有一次实测实例的类,加一道常设门是用永久成本买一次性收益;#14100 上的一条笔记足以让下一个扫这个包的人用 per-it() 的 AST 走查而不是文件级 grep。⚠️ 若 #14100 的两个 population 落地后又出现第三次,届时再谈建门 —— 那时它就是三个实例而不是一个。
