Yig'ish posting (`assemble`) — atomik, §6.4 tannarx

Bajarildi

Status:

Tavsif

`set_assembly.create` rule (⚠️ `source = auto_order` da rule **talab qilinmaydi** — tizim tranzaksiyasi, 06 R14). **Bitta atomik tranzaksiya** (qoida 38): a. Resept snapshot: `recipe_version_id` hujjatga yoziladi. b. Node'ning `semi_finished` omboridan har komponent uchun `postOut(...)` (`condition = good`, `movementType = assembly_out`, `sourceType = assembly`, `assemblyGroupId`) → grain 🅰️ qatlamlar. Har qatlam uchun `set_assembly_lines` qatori: `batch_id`, `qty`, `unit_cost`, 🔴 `line_cost` = **qoida 42 bo'yicha ajratilgan aniq qiymat** (`qty × unit_cost` emas). c. Node'ning `finished` omborida `postIn(...)` (`sourceType = assembly`, `totalCost = Σ line_cost`) → yangi partiya + `assembly_in` movement. d. `set_assemblies` hujjati `status = posted`, `total_cost = Σ line_cost`. 🔴 **Ishbay YO'Q** (qoida 39): set yig'ish `wage_entries` yozuvini **yaratmaydi** — set tannarxi faqat komponent FIFO (§6.4), ishlab chiqarish tannarxidan (material + ishbay) farqli. 🔴 **Qisman yig'ish YO'Q**: komponent yetmasa yoki band bo'lsa operatsiya **butunlay** rad etiladi. 🔴 **Bir qadamli**: `draft` holati yo'q, "kirim qilish" bosilganda darhol post qilinadi. Ko'p komponentli amalda qulf tartibi CROSS_CUTTING Q bo'yicha.

=== QA 3-TUR (qa-EP-04-T07-S02, 2026-08-21) — commit 9234f3c — ✅ QABUL QILINDI === [N1] YOPILDI ✅ — qulf to'qnashuvi endi `409 STOCK_BUSY` (500 EMAS), ishlash vaqtida isbotlandi. PROBE (2-turdagi ssenariyning aynan o'zi, endi test sifatida kodlangan — SetAssemblyCreateTest.java:509 `assembleRetriesOnSustainedLockContentionThenReturnsStockBusy`: raqib xom JDBC ulanishi MAQSAD `stock` qatorini `FOR UPDATE` bilan butun so'rov davomida ushlaydi; `finished` ombor id < `semi` ombor id -> `lockStockRowsInOrder` aynan shu qatorni BIRINCHI qulflaydi). Wire darajasidagi o'lchov (bitta request_id bo'yicha ilova log'i): 09:21:49.837 POST /api/v1/set-assemblies 09:21:52.950 SQLState 55P03 (canceling statement due to lock timeout) <- 1-urinish, ~3.1s 09:21:56.232 SQLState 55P03 <- 2-urinish, +3.28s 09:21:59.504 SQLState 55P03 <- 3-urinish, +3.27s 09:21:59.534 Completed 409 CONFLICT, body code = STOCK_BUSY JAMI: 9 697 ms (test o'z o'lchovi bilan >= 8 500 ms ni ham tasdiqlaydi). (b) Retry TASHQI ekani — shu log'ning O'ZI isbot: uchala urinish ham TO'LIQ 3s qulf kutishiga tushgan. Participating (ichkarida qolgan) retry bo'lganida 2- va 3-urinish darhol `25P02 in_failed_sql_transaction` bilan yiqilardi, qayta 3s kutmasdi — ya'ni har urinish chindan YANGI jismoniy tranzaksiya va `SET LOCAL lock_timeout` qaytadan qo'yilgan. Naqsh etalon bilan bir xil: SetAssemblyService.java:244-261 = WarehouseTransferService:297-313. Retry soni/jitter Q p.4 ga mos: LOCK_MAX_RETRIES=2 (jami 3 urinish), jitter 50-200ms (bytecode: `iconst_2` + `if_icmple`, SetAssemblyService.java:87-89). TAKRORIY YOZUV XAVFI YO'Q (strukturaviy): (1) `open-in-view: false` (application.yml:38) -> har urinishga YANGI EntityManager, oldingi urinishning persistence context'i keyingisiga sizib o'tmaydi; (2) `SetAssemblyPoster#assemble` ichidagi butun holat metod-lokal (yangi `SetAssembly`, har urinishda YANGI `assemblyGroupId`); (3) `stockRepository.insertIfAbsent` — oddiy `@Modifying` native INSERT (REQUIRES_NEW emas), tranzaksiya bilan birga rollback bo'ladi; (4) D2 testi yozuv boshlangandan keyingi to'liq rollback'ni allaqachon isbotlaydi; (5) N1 testi 3 urinishdan keyin set_assemblies/set_assembly_lines/stock_movements = 0 va qoldiqlar tegilmagan ekanini tekshiradi. (c) D1 REGRESSIYA YO'Q ✅ — tranzaksiya chegarasi ko'chgan bo'lsa-da, `setLockTimeoutForCurrentTransaction()` hali ham atomik tananing ILK instruksiyasi. Bytecode (`javap -c target/classes .../SetAssemblyPoster.class`), `assemble(...)`: 0: aload_0 / 1: getfield stockRepository / 4: invokeinterface StockRepository.setLockTimeoutForCurrentTransaction:()V Undan oldin hech qanday chaqiruv yo'q (SetAssemblyPoster.java:131). (d) YANGI TEST BO'SH EMAS — 2 mutatsiya bilan isbotlandi (ikkalasi ham o'ldirildi va tiklandi): M1 (retry qobig'i olib tashlandi, SetAssemblyService:245-260 -> to'g'ridan-to'g'ri `transactionTemplate.execute(...)`): -> `Completed 500 INTERNAL_SERVER_ERROR`, test YIQILDI `expected: 409 CONFLICT`, metod vaqti 4.888s (bitta urinish). M2 (`LOCK_MAX_RETRIES = 2` -> `0`): javob 409 STOCK_BUSY bo'lib QOLDI, lekin vaqt assert'i YIQILDI: `Expecting actual: 3855L to be greater than or equal to: 8500L`. Ya'ni test faqat kodni emas, Q p.4 dagi URINISHLAR SONINI ham qotiradi. Tiklash: faqat `git checkout -- src/main/java/uz/erpbom/warehouse/service/SetAssemblyService.java` (`git checkout .` / `git stash` ISHLATILMADI — EP-04-T12 fayllari tegilmagan). Tiklangach `javap` bilan target/classes toza ekani tasdiqlandi (`iconst_2`, `STOCK_BUSY`, `sleepJitter`, `goto` retry sikli joyida) va ishchi daraxt toza (`git status --porcelain` bo'sh). (e) VAKUUM ASSERT YOPILDI ✅ — `countRows("set_assembly_lines") == 0` assert'i o'chirildi va o'rniga haqiqatga mos izoh qo'yildi (SetAssemblyCreateTest.java:478-482: `saveAll` sikldan KEYIN, xato sikl ICHIDA -> bu yo'lda jadval hech qachon yozilmaydi). Uning o'rniga ketma-ketlik (sequence) o'sishi tekshiriladi (`sequenceLastValue`, :455-465) — yolg'on da'vo qolmagan. (f) 1-2-TURDA TASDIQLANGANLAR BUZILMAGAN ✅ — mexanik isbot: tranzaksiyali tana `SetAssemblyService#assemble` (04a3e00) dan `SetAssemblyPoster#assemble` ga AYNAN ko'chirilgan. Normalizatsiyalangan (izohlarsiz, faqat ma'lum chaqiruv almashtirishlari: `stockPostingService.postOut/postIn` -> `stockOutPoster.post`/`stockInPoster.post`, tekshiruvlar -> `SetAssemblyResolver`) solishtirish: MATNAN IDENTIK. Ya'ni qulf tartibi Q p.1, qoida 42 ajratish, FIFO ASC, band (`qty_reserved`) chegirish, qoida 39 (wage_entries yo'q), `draft` yo'qligi (`status=posted`), `recipe_version_id` snapshot, D2 rollback, D3 `assembly_group_id`, kontraktga moslik — o'zgarmagan va testlar bilan qoplangan (6/6 AC). Atomiklik (qoida 38) saqlangan: `StockOutPoster#post`/`StockInPoster#post` — `@Transactional` default PROPAGATION_REQUIRED, ya'ni poster'ning tranzaksiyasiga QO'SHILADI, alohida emas. `StockPostingService.postOut/postIn` — faqat retry o'ramasi (qo'shimcha mantiq yo'q), shu sabab to'g'ridan-to'g'ri poster chaqirig'i hech narsa yo'qotmaydi (WarehouseTransferShipPoster bilan bir xil). Kontrakt: openapi/v1/warehouse.yaml — `SetAssemblyConflict` (409) katalogida `STOCK_BUSY` (:2778), `POST /api/v1/set-assemblies` javoblarida 409 -> SetAssemblyConflict (:2236). MOS. CROSS-CUTTING: @Transactional qatlami joyida (`assemble` — ataylab tranzaksiyasiz retry qobig'i, o'zi DB'ga tegmaydi; `preview` — readOnly=true; haqiqiy ish — poster'da); migratsiya o'zgarmagan (tenant/precision/snake_case/soft-delete tegilmagan); yangi log/parol/token yozuvi yo'q. TESTLAR (o'zim yurgizdim, qulf ostida, `clean`siz): flock /var/tmp/erpbom-build.lock mvn -o -Dtest=SetAssemblyCreateTest test -> Tests run: 9, Failures: 0, Errors: 0, Skipped: 0 — BUILD SUCCESS (54.7s). Mutatsiyalardan keyin tiklab QAYTA yurgizildi -> yana 9/9 yashil (46.8s). N1 testining o'zi: 9.955s (probe 9.7s + setup).

coder-ep-04-t07-s02 izoh qoldirdi

3-tur (coder-EP-04-T07-S02, opus, 2026-08-21) — commit 9234f3c. [N1] YOPILDI. SABAB: `assemble()` da retry qobig'i yo'q edi; `lockStockRowsInOrder` dagi `55P03` to'g'ridan-to'g'ri `GlobalExceptionHandler#handleUnexpected` ga tushib `500 INTERNAL_ERROR` berardi. Kontrakt (openapi/v1/warehouse.yaml:2778 `SetAssemblyConflict` -> `STOCK_BUSY`) va CROSS_CUTTING Q p.4/p.5 buzilgan edi. TUZATISH (etalon: `WarehouseTransferService#shipWithRetry`): 1. `SetAssemblyPoster` (YANGI, package-private `@Service`, `@Transactional assemble(...)`) — yig'ishning butun atomik tanasi shu yerga ko'chdi. `stockRepository.setLockTimeoutForCurrentTransaction()` — ILK instruksiya (D1 saqlandi, bytecode bilan tekshirildi: `javap -c SetAssemblyPoster` -> offset 0/1/4 = `invokeinterface StockRepository.setLockTimeoutForCurrentTransaction`). 2. `SetAssemblyService#assemble` — ARTIQ `@Transactional` EMAS: `new TransactionTemplate(transactionManager)`, `LOCK_MAX_RETRIES = 2`, jitter 50-200ms, `isRetryableLockFailure` (`40P01`/`55P03` sabab zanjirida), 3-urinishdan keyin `BusinessConflictException("STOCK_BUSY", ...)` -> 409. Retry TASHQI: har urinish chindan YANGI jismoniy tranzaksiya, ya'ni `SET LOCAL lock_timeout='3s'` ham qaytadan qo'yiladi. 3. `SetAssemblyResolver` (YANGI) — `requireFinishedVariant`/`requireActiveRecipe`/`requireFinishedWarehouse`/ `requireSemiFinishedWarehouse` YAGONA nusxada; `preview` ham, `assemble` ham SHU metodlarni chaqiradi. Sabab: tana ikkinchi bean'ga ko'chgach nusxalash S01 dagi "preview va create bir xil kod/xabar berishi shart" talabini buzardi. 4. `StockOutPoster`/`StockInPoster` endi TO'G'RIDAN-TO'G'RI chaqiriladi (`StockPostingService` EMAS) — `WarehouseTransferShipPoster` bilan bir xil. Sabab: `StockPostingService` ning ichki `TransactionTemplate` retry'i participating tranzaksiyada 2-urinishni ABORT bo'lgan tranzaksiyada bajarardi va haqiqiy `55P03` ni `25P02` bilan NIQOBLAB, tashqi retry xatoni tanimay qolishi mumkin edi. (Bu oqimda barcha qatorlar oldindan qulflangani uchun amalda yuz bermasdi, lekin sinf javadoc'idagi "asos yaroqsiz" da'vosi ham shu bilan tuzatildi.) TEST (QA retsepti bo'yicha): `assembleRetriesOnSustainedLockContentionThenReturnsStockBusy` — `finished` ombor `semi` dan OLDIN yaratiladi (id kichik -> `lockTargetFirst = true`), maqsad `stock` qatori oldindan `insertStock(..., "0.0000", "0")`; raqib XOM JDBC ulanishi shu qatorni `FOR UPDATE` bilan butun HTTP so'rovi davomida ushlaydi (`StockPostingServiceTest#postOutRetries...` bilan bir xil naqsh — alohida thread/latch shart emas, so'rov Tomcat oqimida bajariladi). Natija: `409` + `code = STOCK_BUSY`, o'tgan vaqt >= 8500 ms. TESTLAR: `flock /var/tmp/erpbom-build.lock mvn -o -Dtest=SetAssemblyCreateTest,SetAssemblyPreviewTest test` -> Tests run: 19, Failures: 0, Errors: 0 — BUILD SUCCESS (SetAssemblyCreateTest 9/9). MUTATSIYA (4 ta, hammasi O'LDIRILDI): A. retry qobig'i olib tashlandi (faqat `transactionTemplate.execute`) -> `expected: 409 CONFLICT`, amalda 500 (`handleUnexpected`), ~3.9s. YIQILDI. B. `LOCK_MAX_RETRIES = 2 -> 0` -> 409 STOCK_BUSY keldi, LEKIN 3990 ms -> vaqt assert'i YIQITDI (ya'ni ">= 8.5s" da'vosi bo'sh emas, chindan 3 urinishni talab qiladi). C. hujjat `save(assembly)` sikldan keyinga surildi -> D2 dagi YANGI `set_assemblies` sequence assert'i YIQITDI (`0 > 0`). D. `StockOutPoster:122 stockMovementRepository.save(movement)` o'chirildi -> D2 dagi `stock_movements` sequence assert'i YIQITDI (`0 >= 2`). Hammasi backup nusxadan tiklandi (`git checkout` ISHLATILMADI — ishchi daraxtda EP-04-T12 fayllari bor); `grep -rn MUTATSIYA src/` -> bo'sh, `git status` -> faqat shu bargning 4 fayli. QA NING KICHIK ESLATMASI (vakuum assert) — bajarildi: `SetAssemblyCreateTest:451` dagi `set_assembly_lines` assert'i olib tashlandi va o'rniga HAQIQATNI aytuvchi izoh qo'yildi (`saveAll` sikldan keyin turadi, xato sikl ichida -> bu yo'lda u jadval hech qachon yozilmaydi; haqiqiy qamrov `assembleMatchesWorkedExampleFromSpec` da 4 qator). Bo'shliqni qoplash uchun D2 ga QA probe'ining o'zi TEST ichiga ko'chirildi: `set_assemblies_id_seq` va `stock_movements_id_seq` o'sishi tekshiriladi (sequence rollback bo'lmaydi -> "yozuv chindan boshlangan" ning yagona guvohi). Endi D2 tashqi probe'ga tayanmaydi (mutatsiya C/D shuni isbotladi). QAYTA BUZILMAGAN: D1 (ILK instruksiya — bytecode), qulf tartibi Q p.1, qoida 42, FIFO ASC, band chegirish, qoida 39, `draft` yo'q, `recipe_version_id` snapshot, D3 `assembly_group_id`. Kontrakt (`openapi/v1/warehouse.yaml`) O'ZGARTIRILMADI. `erp/docs` ga yozilmadi.

=== QA 2-TUR (qa-EP-04-T07-S02, 2026-08-21) — commit 04a3e00 === Uchala 1-tur topilmasi YOPILDI (har biri mutatsiya bilan isbotlandi), lekin D1 tuzatishi YANGI kontrakt buzilishini ochib berdi (N1) — shu sabab qaytarilmoqda. [D1] YOPILDI ✅ — `setLockTimeoutForCurrentTransaction()` endi haqiqatan BIRINCHI. Bytecode: `javap -c target/classes uz.erpbom.warehouse.service.SetAssemblyService` — `assemble(...)` metodining 0/1/4-offsetdagi ILK instruksiyasi `invokeinterface StockRepository.setLockTimeoutForCurrentTransaction:()V` (SetAssemblyService.java:261). Hech qanday chaqiruv undan oldin turmaydi. Ishlash vaqti isboti (QA probe): raqib xom JDBC ulanishi MAQSAD `stock` qatorini (`finished` ombor id < `semi` ombor id -> `lockStockRowsInOrder` aynan shu qatorni BIRINCHI qulflaydi, SetAssemblyService:349-357) 15s `FOR UPDATE` bilan ushlaydi: - tuzatish bilan : javob 3987 ms da uzildi (lock_timeout=3s ISHLADI); - MUTATSIYA (261-qator olib tashlandi): 15272 ms KUTDI va `201 CREATED` qaytardi -> probe YIQILDI. Mutatsiya o'ldirildi. [D2] YOPILDI ✅ — yangi test yozuvlar BOSHLANGANDAN KEYIN yiqiladi. `assembleRejectsWhenComponentBatchInvariantBreaksAfterWritesStartedAndRollsBackCompletely` (SetAssemblyCreateTest.java:403). Isbot — ketma-ketlik (sequence) tranzaksiyaga bo'ysunmaydi, shu sabab QA probe so'rovdan oldin/keyin o'lchadi: `set_assemblies_id_seq` 0 -> 1, `stock_movements_id_seq` 0 -> 2 ya'ni hujjat INSERT'i + 2 ta harakat INSERT'i (Stol 1 qatlam + Stul qisman 1 qatlam) CHINDAN bajarilgan, keyin rollback ularni tozalagan (`set_assemblies`=0, `stock_movements`=0). Strukturaviy sabab: `SetAssembly`/`StockMovement` — `GenerationType.IDENTITY`, `save()` INSERT'ni darhol yuboradi. MUTATSIYA (`StockOutPoster:129` invarianti `if (false && ...)` bilan yumshatildi) -> test YIQILDI: `expected: 500 INTERNAL_SERVER_ERROR but was: 201 CREATED`. O'ldirildi. ⚠️ Kichik eslatma (defekt EMAS, tuzatish talab qilinmaydi): shu ssenariyda `set_assembly_lines` baribir hech qachon yozilmaydi — `saveAll` (SetAssemblyService:324) komponent siklidan KEYIN turadi, xato esa sikl ICHIDA otiladi. Ya'ni SetAssemblyCreateTest:451 dagi assert vakuum; qolgan 3 jadval + qoldiq assert'lari haqiqiy. [D3] YOPILDI ✅ — `stock_movements.assembly_group_id` hujjatnikiga tenglik tekshiriladi. SetAssemblyCreateTest.java:221-223 — hujjat `assembly_group_id` i olinadi, bo'sh emasligi va `stock_movements` da shu qiymatli qatorlar soni = 5 (4 assembly_out + 1 assembly_in). MUTATSIYA (`StockOutPoster:118` -> `setAssemblyGroupId(null)`) -> `assembleMatchesWorkedExampleFromSpec` YIQILDI: `expected: 5 but was: 1`. O'ldirildi. TESTLAR: `flock /var/tmp/erpbom-build.lock mvn -o -Dtest=SetAssemblyCreateTest test` -> Tests run: 8, Failures: 0, Errors: 0, Skipped: 0 — BUILD SUCCESS. Barcha mutatsiyalar `git checkout -- <aniq fayl>` bilan tiklandi; `javap` bilan target/classes da mutatsiya qoldig'i YO'Qligi tasdiqlandi (`setAssemblyGroupId` va `IllegalStateException` joyida). Ishchi daraxt toza. 1-TURDA TASDIQLANGANLAR BUZILMAGAN (qayta ko'rildi): qulf TARTIBI Q p.1 (komponentlar `componentVariantId` ASC + maqsad qator ombor id bo'yicha oldin/keyin), qoida 42 ajratish (StockOutPoster:88-97), FIFO ASC, band (`qty_reserved`) chegirish, qoida 39 (wage_entries yo'q), `draft` yo'q (`status=posted` qotirilgan), `recipe_version_id` snapshot, kontraktga moslik, precision (18,4)/(18,2), snake_case / soft-delete / AR-1 — hammasi joyida. Ishlab chiqarish kodida o'zgargan yagona narsa — 261-qatordagi chaqiruv + izoh. === ❌ QAYTARISH SABABI — [N1] (1 ta, YANGI: D1 tuzatishi ochib bergan yo'l) === [N1] KONTRAKT + CROSS_CUTTING Q p.4/p.5 BUZILGAN — qulf to'qnashuvida `500 INTERNAL_ERROR` qaytadi, kutilgani `409 STOCK_BUSY`. Fayl: src/main/java/uz/erpbom/warehouse/service/SetAssemblyService.java:253-270 (retry qobig'i YO'Q); sinf javadoc'i :64-69 (ataylab yo'q deb yozilgan). DALIL (QA probe, D1 stsenariysi, tuzatish BILAN ishlagan holat): javob 3987 ms da -> HTTP 500 {"code":"INTERNAL_ERROR","message":"Kutilmagan xatolik yuz berdi","request_id":"..."} (GlobalExceptionHandler#handleUnexpected — `55P03 lock_not_available` uchun aniq handler yo'q). KUTILGAN: - CROSS_CUTTING Q p.4 — `40P01`/`55P03` da butun tranzaksiya QAYTA boshlanadi, maksimum 2 marta, orasida jitter 50-200 ms; - CROSS_CUTTING Q p.5 — 3-urinishdan keyin sinxron (HTTP) oqimda `409 STOCK_BUSY`. - Q ning qamrov ro'yxati "03_warehouse (ko'chirish, chiqim, SET YIG'ISH/tarqatish, inventarizatsiya)" — bu oqim nomma-nom sanalgan. - Kontrakt (T00 MUZLATILGAN): openapi/v1/warehouse.yaml:2778 — `SetAssemblyConflict` (409) katalogida `STOCK_BUSY` e'lon qilingan, `POST /api/v1/set-assemblies` javoblarida 409 -> SetAssemblyConflict (:2237). Ya'ni endpoint `STOCK_BUSY` qaytara olishi SHART; hozir bu kod HECH QACHON chiqmaydi. NEGA AYNAN HOZIR: D1 gacha birinchi qulflar Postgres default `lock_timeout = 0` bilan olinardi — `55P03` UMUMAN yuz bermasdi (cheksiz kutish, probe buni ko'rsatdi: 15272 ms kutib 201 qaytardi). D1 tuzatishi 3s chegarani joriy qildi -> endi `55P03` real yo'l va u to'g'ridan-to'g'ri foydalanuvchiga 500 bo'lib chiqmoqda. (`40P01` ham 500 berardi — teshik avval ham bor edi, D1 uni FAOLLASHTIRDI.) NEGA `postOut`NING ICHKI RETRY'I YORDAM BERMAYDI: StockPostingService javadoc'ining o'zi yozgan (StockPostingService.java:43-58) — `TransactionTemplate` `PROPAGATION_REQUIRED` tashqi tranzaksiyaga QO'SHILADI, tashqi tranzaksiya rollback-only bo'lgach ichkaridan qayta boshlab bo'lmaydi. Qolaversa bu to'qnashuv `lockStockRowsInOrder` (270-qator) da yuz beradi — `postOut`ga umuman yetib bormaydi. SINF JAVADOC'IDAGI ASOS YAROQSIZ: ":64-69 — `postOut`lar `postIn`dan oldin BITTA jismoniy tranzaksiyada bo'lishi shart, shu sabab tashqi-retry naqshi EMAS". Aynan shu repo'da `WarehouseTransferService.shipWithRetry` (WarehouseTransferService.java:297-313) ko'p `postOut`ni BITTA `@Transactional` (`WarehouseTransferShipPoster.ship`) ichida bajarib turib, retry siklini o'sha tranzaksiyaning TASHQARISIDA yuritadi — ikki talab bir-biriga zid emas. TUZATISH (aniq): `WarehouseTransferService.shipWithRetry` naqshini takrorla — 1. `assemble()` ning `@Transactional` tanasini ALOHIDA bean'ga ko'chir (mas. `SetAssemblyPoster`, package-private `@Transactional` metod — `WarehouseTransferShipPoster` kabi; o'sha sinfda self-invocation proxy'ni chetlab o'tgani uchun alohida bean SHART); 2. `SetAssemblyService.assemble(...)` faqat retry siklini yuritsin: `new TransactionTemplate(transactionManager)`, `MAX_RETRIES = 2`, jitter 50-200 ms, `isRetryableLockFailure` (sabab zanjirida `40P01`/`55P03`); 3. 3-urinishdan keyin `throw new BusinessConflictException("STOCK_BUSY", ...)` -> 409. `SET LOCAL lock_timeout` chaqiruvi har urinishda yangi tranzaksiyada qayta qo'yiladi (D1 saqlanib qoladi). TEST (talab qilinadi — QA probe'ini takrorla): Setup: `finished` ombor `semi` dan OLDIN yaratilsin (id kichik) -> maqsad `stock` qatori BIRINCHI qulflanadi; o'sha qator oldindan `insertStock(finishedWarehouseId, setId, "good", "0.0000", "0")` bilan yaratilsin. Raqib: alohida thread xom JDBC ulanishida `SELECT id FROM stock WHERE warehouse_id=? AND product_variant_id=? AND condition='good' FOR UPDATE`, `CountDownLatch` bilan signal beradi, ~15s ushlab turadi (3 urinish x 3s = 9s dan UZOQ bo'lishi shart), keyin `rollback()`. Kutilgan: `POST /api/v1/set-assemblies` -> `409` + `code = STOCK_BUSY`, o'tgan vaqt >= ~8.5s (3 urinish x 3s), `201` EMAS va `500` EMAS.

QA 2-tur: D1/D2/D3 YOPILDI (uchalasi mutatsiya bilan isbotlandi), testlar 8/8 yashil. Lekin D1 tuzatishi YANGI kontrakt buzilishini ochdi [N1]: qulf to'qnashuvida 500 INTERNAL_ERROR qaytadi, kontrakt (warehouse.yaml:2778 SetAssemblyConflict) va CROSS_CUTTING Q p.4/p.5 esa 2 marta retry + 409 STOCK_BUSY talab qiladi. Tafsilot technical_notes da [N1].

QA (qa-EP-04-T07-S02) — 6 ta AC ham TEKSHIRILDI va o'tdi (2505-2510 is_met=true), testlar yashil: `mvn -o -Dtest=SetAssemblyCreateTest test` -> Tests run: 7, Failures: 0, Errors: 0. Mutatsiya sinovi (3/3 O'LDIRILDI): (a) line_cost -> qty x unit_cost [SetAssemblyService:310] -> assembleAllocatesExactBatchCostNotQtyTimesUnitCost:299 YIQILDI (0.51 != 0.50); (a2) qoida 42 ajratish -> naiv [StockOutPoster:90-97] -> o'sha test YIQILDI (remaining_cost manfiy, 500); (b) FIFO ASC -> DESC [StockBatchRepository:29] -> assembleMatchesWorkedExampleFromSpec:174 YIQILDI (4 000 000 != 3 880 000); (c) band chegirish olib tashlandi [SetAssemblyService:376] -> assembleExcludesReservedQtyFromAvailability:382 YIQILDI. Bytecode javap bilan tiklanganligi tasdiqlandi (ORDER BY receivedAt ASC, getRemainingCost mavjud); ishchi daraxt toza (faqat EP-04-T12 ning 3 fayli). === QAYTARISH SABABI (1 defekt + 2 test bo'shligi) === [D1] CROSS_CUTTING Q p.3 BUZILGAN — birinchi qulfdan oldin `SET LOCAL lock_timeout = '3s'` qo'yilmagan. Fayl: src/main/java/uz/erpbom/warehouse/service/SetAssemblyService.java:253-270. `assemble()` tranzaksiyani ochadi va 270-qatorda `lockStockRowsInOrder(...)` ni chaqiradi; birinchi haqiqiy `SELECT ... FOR UPDATE` — `lockTargetRow` (360-qator) va `requireComponentAvailable` (373-qator) ichidagi `stockRepository.findForUpdate(...)`. Bu paytga qadar `stockRepository.setLockTimeoutForCurrentTransaction()` HECH QAYERDA chaqirilmagan — u faqat keyinroq, `StockOutPoster.post` (StockOutPoster.java:58) ichida, ya'ni 297-qatordagi `postOut` chaqiruvidan keyin ishlaydi. Kutilgan: CROSS_CUTTING Q p.3 — "Har bunday tranzaksiya OCHILGANDA qo'yiladi — cheksiz kutish yo'q"; `StockRepository.setLockTimeoutForCurrentTransaction()` javadoc'i ham: "har qulflovchi tranzaksiya boshida qo'yiladi". Olingan: bu oqimning BIRINCHI qulflari (komponent `stock` qatorlari + maqsad qator, `insertIfAbsent` ning ON CONFLICT kutishi ham) Postgres default `lock_timeout = 0` (CHEKSIZ kutish) bilan olinadi. Raqib assemble/transfer.ship shu qatorni ushlab tursa, so'rov 3s emas, cheksiz osiladi. Repo'dagi etalon (o'sha epic, avvalgi QA topilmasi bilan kiritilgan): WarehouseTransferShipPoster.java:97-104 — `@Transactional ship(...)` ning BIRINCHI operatori `stockRepository.setLockTimeoutForCurrentTransaction();`, izohi: "CROSS_CUTTING Q p.3 — BIRINCHI qulfdan (transfer hujjat qatoridan) oldin". Xuddi shu naqsh WarehouseTransferService.java:413/425 da ham. Tuzatish: `assemble()` ning boshiga (255-qatordan oldin, tranzaksiya ochilishi bilan) `stockRepository.setLockTimeoutForCurrentTransaction();` qo'shilsin. `SET LOCAL` idempotent — StockOutPoster/StockInPoster ichida takrorlanishi zararsiz (WarehouseTransferShipPoster izohi shuni ochiq yozgan). [D2] TEST BO'SHLIGI — atomiklik (qoida 38) YOZUV BOSHLANGANDAN KEYINGI xato bilan isbotlanmagan. Fayl: src/test/java/uz/erpbom/warehouse/controller/SetAssemblyCreateTest.java:311-360 (`assembleRejectsWhenComponentInsufficientAndRollsBackCompletely`). Testning izohi "full-rollback Stol'ga ham tegishli ekanini isbotlaydi" deydi, lekin bu NOTO'G'RI: `lockStockRowsInOrder` (SetAssemblyService:270) HAMMA komponentni OLDINDAN tekshiradi, shuning uchun STOCK_INSUFFICIENT `setAssemblyRepository.save(assembly)` (291-qator) va birinchi `postOut` (297-qator) dan OLDIN otiladi — hech narsa yozilmagan holda "rollback" tasdiqlanmoqda (bo'sh tekshiruv). Kerak: yozuvlar boshlangandan KEYIN yiqiladigan deterministik ssenariy. Tayyor retsept: ikki komponent (Stol id kichik, to'liq ta'minlangan; Stul), Stul uchun `stock.qty_on_hand = 20` lekin `stock_batches` da faqat `qty_remaining = 5` bitta qatlam. Oldindan tekshiruv o'tadi (20 >= 20), `set_assemblies` yoziladi, Stol `postOut` i muvaffaqiyatli o'tadi, so'ng Stul `postOut` i StockOutPoster.java:129-136 dagi invariant himoyasida (`IllegalStateException`) yiqiladi. Tasdiqlansin: `set_assemblies` = 0, `set_assembly_lines` = 0, `stock_movements` = 0, Stol `qty_on_hand` va uning `stock_batches.qty_remaining`/`remaining_cost` O'ZGARMAGAN. Shu test [D1] tuzatilgandan keyin ham yashil qolishi kerak. [D3] TEST BO'SHLIGI — `assembly_group_id` ning `stock_movements` bilan bog'lanishi tasdiqlanmagan. Board tavsifi `assemblyGroupId` to'ldirilganini talab qiladi. Kod to'g'ri (SetAssemblyService:299 va :320 uzatadi, StockOutPoster:117-119 va StockInPoster:112 yozadi), lekin testdagi `distinctAssemblyGroupIdCount()` (SetAssemblyCreateTest:748) FAQAT `set_assemblies` ni sanaydi. Kerak: `assembleMatchesWorkedExampleFromSpec` da 4 ta `assembly_out` + 1 ta `assembly_in` harakatining `assembly_group_id` i hujjatning `assembly_group_id` iga TENG ekani va NULL emasligi tasdiqlansin (aks holda bu maydonni butunlay unutgan mutatsiya omon qoladi). === Defekt EMAS (tekshirildi, izchil) === - Atomiklik mexanikasi: `assemble` @Transactional; postOut/postIn `TransactionTemplate` (PROPAGATION_REQUIRED) orqali TASHQI tranzaksiyaga QO'SHILADI — bitta jismoniy tranzaksiya (qoida 38 mexanikasi to'g'ri; isboti yetishmayapti — [D2]). - Qulf TARTIBI (CROSS_CUTTING Q p.1): to'liq kalit ASC — komponentlar `componentVariantId` ASC (SetAssemblyService:107-108, 263), maqsad qator ombor id'si bo'yicha oldin/keyin (345-354). To'g'ri. - Qoida 39: `wage_entries` jadvali migratsiyalarda umuman yo'q, SetAssemblyService konstruktorida (110-118) employees/wage bog'liqligi yo'q; `assembleTouchesOnlyExpectedTables` DB darajasida tasdiqlaydi. - Qoida 42: `line_cost` = `consumption.totalCost()` (SetAssemblyService:310), u StockOutPoster:91-97 da ajratiladi — qatlam TUGAGANDA qolgan BUTUN `remaining_cost` olinadi (yaxlitlash qoldig'i oxirgi donaga yopishadi), aks holda proporsional round(.,2). Mutatsiya (a)/(a2) buni tasdiqladi. - `draft` yo'q: `status = posted` qotirilgan (SetAssemblyService:287), migratsiya CHECK (V18:357-358) faqat posted|reversed. - `recipe_version_id` snapshot: 282-qator; test 219/259-qatorlarda tasdiqlangan. - Kontrakt: openapi/v1/warehouse.yaml:2178-2237 (yo'l, 201, xato kodlari) va :4762-4949 (maydon nomi/tip) DTO'lar bilan mos; `set_assembly.create` rule (SetAssemblyController:45,55); 409 kodlar (STOCK_INSUFFICIENT / SET_RECIPE_MISSING / WAREHOUSE_TYPE_INVALID / SEMI_FINISHED_WAREHOUSE_MISSING) SetAssemblyConflict katalogida (:2759-2779) bor. Chetga chiqish yo'q. - Precision: V18:325/328 qty numeric(18,4), total_cost numeric(18,2); V18:429-431 lines qty (18,4), unit_cost/line_cost (18,2). To'g'ri. - snake_case, ko'plik jadval, to'liq nomdan FK, fizik DELETE yo'q, log'da parol/token yo'q, tenant_id/schema ajratish qo'shilmagan (AR-1). Toza.
