From 89e9753f98e7ba896a693e003c44b99bcda88c2c Mon Sep 17 00:00:00 2001 From: hongwei Date: Thu, 11 Jun 2026 15:25:40 +0200 Subject: [PATCH 01/29] test: add concurrency hazard test suite Adds a tagged ScalaTest suite that simulates 16 confirmed database concurrency hazards in OBP-API: lost-update, check-then-act, check-then-insert, unique-constraint-unhandled, and counter-sequence races across money movement, security, consent scheduling, view permissions, and OAuth user creation paths. Each scenario asserts the theoretically-correct outcome so that a hazard surfaces as a FAILED test (red bar = evidence the hazard is real). Two safeguard scenarios (connection pool back-pressure, per-request context isolation) are verified to PASS. All scenarios are tagged ConcurrencyRace and excluded from the CI main flow. See CONCURRENCY_HAZARDS.md for the full taxonomy, source locations, and three-tier protection analysis.

System views are pinned to a global whitelist by `ViewDefinition.beforeSave`/`isValidSystemViewId`, so an isolated test would have to delete a globally-shared system view and pollute other suites (forkMode=once). **N** exercises the identical unguarded path on an isolated custom view. | +| P | `factoryResetSystemView` concurrent reset | Drives `ViewPermission.resetViewPermissions`'s insert path — the exact code **O** already pins. | +| migrateViewPermissions | duplicate ViewPermission insert | Same `ViewPermission` insert-without-`tryo` root cause as **O**. | +| Q | `revokeAccess` vs `grant` check-then-act | Same `AccountAccess` check-then-act family as **R**; the revoke-vs-grant window is narrow, so a non-deterministic barrier test would be flaky (false-green). The check-then-act class is already proven by **R** (orphan) and **J/U** (stale-save). | +| T | `createTransactionRequestBulk` per-leg balance | The verdict's "deterministic intra-request self-race" is **unconfirmed**: `saveTransaction` writes `fromAccount.asInstanceOf[MappedBankAccount].accountBalance(newBalance)` back onto the passed object, so sequential legs see the updated balance, not a stale one. Whether `BulkPaymentHandler.executeAllItems` re-resolves the account per leg needs further investigation before asserting. The concurrent-reuse mechanism it shares with **S** is already proven; writing a possibly-false test here was rejected. | +| V | Berlin Group `usesSoFarTodayCounter` lost-increment | Same counter lost-update class as **H/K**. Needs a fully-signed recurring Berlin Group consent + TPP headers to reach the increment branch — disproportionate setup for a class already proven. | +| X | Consumer rate-limit `underConsumerLimits` check-then-INCR (TOCTOU) | Real and high-impact (limit bypass), but the active-limit lookup is cached for ~1 hour (`RateLimitTest` documents this) and the Redis TTL+GET+INCR timing makes an HTTP-layer test unreliable (flaky). Confirmed by source audit; a flaky test would undermine "red bar = reliable evidence." | +| Y | `AuthRateLimiter` cold-start SET-vs-INCR collision | Same rate-limit class as **X**; depends on Redis timing and runs in shadow mode by default (non-blocking). Same flakiness concern. | +| Z | `MappedAgentProvider.updateAgentStatus` | Re-audited as **not a hazard**: it sets both fields and `saveMe()`s the whole row; an H2 single-row UPDATE is atomic, so concurrent calls are normal last-writer-wins PUT semantics, not field tearing or data loss. A genuine lost-update would need multiple partial-update endpoints doing read-modify-write on the same row — no such code path exists. | + +## Refuted by audit (genuinely safe — documents what is NOT broken) + +| Symbol | Why safe | +|---|---| +| `createAccountIfNotExisting` (`LocalMappedConnectorInternal.scala:283`) | The whole `find()`-then-`create()` is wrapped in `tryo`; the `UniqueIndex(bank, theAccountId)` violation on the second concurrent insert is caught and converted to `Empty`/`Failure`, not an uncaught 500. The caller handles `Empty` gracefully. This is the correct pattern that **I/L/M/N/O** are missing. | + +## The three-tier protection picture + +| Tier | DB constraint? | App guard? | Scenarios | +|---|:---:|:---:|---| +| Silent data corruption | ✗ | ✗ | A, S, H, K, AA, J, U, C, D, R | +| Uncaught 500 / swallowed Failure | ✓ | ✗ | I, L, N, O, W | +| Gracefully handled | ✓ | ✓ (`tryo`) | F, `createAccountIfNotExisting` | +| Safeguard verified | — | ✓ | G1, G2 | + +The most dangerous tier is silent corruption: H and K turn a balance/counter lost-update into an +authentication **lockout / brute-force bypass**; J and U silently **resurrect a revoked consent** +(a PSD2 compliance breach). When any of these is fixed (atomic UPDATE, optimistic-lock version +column, unique constraint + conflict retry, or a conditional/guarded update), the corresponding +scenario flips from red to green automatically. diff --git a/obp-api/src/test/scala/code/concurrency/ConcurrentConnectionMechanismTest.scala b/obp-api/src/test/scala/code/concurrency/ConcurrentConnectionMechanismTest.scala new file mode 100644 index 0000000000..f6deb2cab1 --- /dev/null +++ b/obp-api/src/test/scala/code/concurrency/ConcurrentConnectionMechanismTest.scala @@ -0,0 +1,86 @@ +/** +Open Bank Project - API +Copyright (C) 2011-2019, TESOBE GmbH. + +This program is free software: you can redistribute it and/or modify +it under the terms of the GNU Affero General Public License as published by +the Free Software Foundation, either version 3 of the License, or +(at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

The underlying data access layer mixes Lift Mapper (for business writes), Doobie (for some queries), and a shared HikariCP connection pool (`autoCommit=false`). + +Through investigation by 3 Explore agents + line-by-line verification, it is confirmed that this mechanism **relies entirely on optimistic concurrency + DB constraints**. There are **no** `SELECT ... FOR UPDATE`, pessimistic locks, or optimistic lock version columns anywhere in the code, nor is there any explicitly set transaction isolation level (using the DB defaults, which is READ COMMITTED for both H2/Postgres). Therefore, multiple classic concurrent write hazards exist: +**Lost updates on balances, double-spending on transaction request state machines, and check-then-insert duplicate creations.** + +The goal of this plan is to **turn these theoretical hazards into runnable, observable evidence using a set of concurrent ScalaTests**. +As per the user's decision: **we will comprehensively cover 6-8 race conditions** and **assert the "theoretically correct behavior"** (if the current code has hazards, it will FAIL and print "expected vs actual"; the red light is the evidence).

Countermeasures: ① Concurrency N≥8; ② If necessary, when instrumentation on the request path is impossible, increase N or repeat rounds; ③ **Print actual observed values when assertions fail** ("expected balance X, actual Y, lost Z transfers"), the red light is the evidence. + - Honest conclusion phrasing: Reproduced in H2 → Postgres will definitely have it (maybe even worse); Not reproduced in H2 ≠ Postgres is safe. + +2. **dispatch HttpClient pool pollution**: Concurrent sharing of `Http.default` sporadically causes `"invalid version format"`, + A retry-once fallback is already in place (`SendServerRequests.scala:154`). → Keep concurrency N around 5-10, tolerate sporadic retries. + +3. **Shared server/DB/pool (`forkMode=once`)**: All suites share a single H2 + Hikari pool. + → Isolate using dedicated prefixes for bank/account/user; cleanup using `wipeTestData()` in `afterEach`; Changing pool size for G1 must use `setPropsValues` (`PropsReset` automatically restores it in `afterEach`, preventing leaks to other suites). + +4. **Red light isolation (Assertion stance = necessary companion to exposing hazards)**: These tests are **expected to FAIL**. + - Tag all with `ConcurrencyRace`. + - Running manually locally: `-n code.concurrency.ConcurrencyRace` (only run these diagnostic tests). + - **Exclude** from CI main flow: The catch-all shard will automatically pick up the `code.concurrency` package → You must add `-l code.concurrency.ConcurrencyRace` (ScalaTest exclude tag) to the CI scalatest invocation, otherwise the catch-all shard will go red. + (This CI change is listed as a follow-up; we will deliver the tests themselves first.) + +5. **request-scoped transaction scope**: Full transactions apply only to v7 native POST/PUT/DELETE; v1-v6 routed through the bridge are committed independently per `DB.use` (the race window is more obvious). The race condition happens at the connector layer, independent of the API version → Just pick any practically available endpoint. + +## File Checklist + +Added (tests only, no business code touched): +- `obp-api/src/test/scala/code/concurrency/ConcurrentRaceSetup.scala` — base trait + `ConcurrencyRace` tag + helpers +- `obp-api/src/test/scala/code/concurrency/ConcurrentTransferRaceTest.scala` — A Balance / B State machine double-spending +- `obp-api/src/test/scala/code/concurrency/ConcurrentDuplicateCreationTest.scala` — C/D/E/F Duplicate creation and state machines +- `obp-api/src/test/scala/code/concurrency/ConcurrentConnectionMechanismTest.scala` — G Connection pool/crosstalk (optional tier) + +Package `code.concurrency` → Falls into the CI catch-all shard (requires exclude tag configuration, see Constraint 4). + +## How to Verify (How to run) + +1. Compile and run this batch of diagnostic tests independently (local, JDK 11): + ```sh + env JAVA_HOME=$JDK11 PATH=$JDK11/bin:$PATH \ + mvn -q -pl obp-commons,obp-api process-resources scalatest:test \ + -DfailIfNoTests=false \ + -Dsuites="code.concurrency.ConcurrentTransferRaceTest code.concurrency.ConcurrentDuplicateCreationTest code.concurrency.ConcurrentConnectionMechanismTest" + ``` +2. Read the output: The failure message for each race scenario should clearly print "expected vs actual" (e.g., "expected balance 899999...000, got 899999...XXX, lost N transfers"), the red light acts as evidence of the hazard. +3. If a scenario sporadically goes green on H2 (masked by table lock serialization), increase the concurrency N / repetition rounds, and annotate the H2 limitation in the test comments. +4. Confirm no pollution to other suites: `afterEach` cleanup + `PropsReset` pool size restoration. + +## Next Steps (Not doing now, just recording the direction) + +Fix directions (separate PR): A/B → `SELECT ...

Production already reads via allowed_actions and writes via ViewPermission.resetViewPermissions, leaving the columns as a legacy data source read only by the one-time migrateViewPermissions bridge. - Reimplement the boolean permission accessors to derive from allowed_actions, making ViewPermission the single source of truth. - Comment out the boolean permission MappedBoolean columns; Schemifier stops managing them while the physical columns remain for a later SQL drop. The MappedText list columns (canGrantAccessToViews_ / canRevokeAccessToViews_) stay. - Remove the migrateViewPermissions bridge, the obsolete MigrationOf* view permission scripts, and their boot wiring in Migration.scala. - Drop the now-moot migrate concurrency scenario and its CONCURRENCY_HAZARDS.md entry, since the migrated method no longer exists.

The concurrency-hazard fix added UniqueIndex to MapperAccountHolders and MappedEntitlements. Schemifier issues CREATE UNIQUE INDEX without a prior duplicate check, so an existing DB with duplicates would fail to start. The SQL file was a manual workaround. The replacement adds Migration.database.deduplicateBeforeUniqueIndexSchemify() directly before schemifyAll() in Boot.scala. It is not gated by migration_scripts.* props (Schemifier itself is not gated), runs as a no-op on fresh/test DBs (table-absent check), and probes for duplicates before issuing the DELETE so it is cheap on healthy databases. On an existing database with duplicates it removes all but the lowest-id row per natural key before the UniqueIndex DDL runs. Also adds DbFunction.tableExistsByName(tableName: String) as a string-based counterpart to the existing tableExists(BaseMetaMapper) helper, to avoid importing the mapper objects inside Migration. --- .../main/scala/bootstrap/liftweb/Boot.scala | 1 + .../code/api/util/migration/Migration.scala | 52 ++++++++++++++++++- .../main/scripts/migrate/migrate_00000020.sql | 31 ----------- 3 files changed, 52 insertions(+), 32 deletions(-) delete mode 100644 obp-api/src/main/scripts/migrate/migrate_00000020.sql diff --git a/obp-api/src/main/scala/bootstrap/liftweb/Boot.scala b/obp-api/src/main/scala/bootstrap/liftweb/Boot.scala index 681f0ad0ee..d160c1f5a0 100644 --- a/obp-api/src/main/scala/bootstrap/liftweb/Boot.scala +++ b/obp-api/src/main/scala/bootstrap/liftweb/Boot.scala @@ -264,6 +264,7 @@ class Boot extends MdcLoggable { */ MapperRules.createForeignKeys_? = (_) => APIUtil.getPropsAsBoolValue("mapper_rules.create_foreign_keys", false) + Migration.database.deduplicateBeforeUniqueIndexSchemify() schemifyAll() logger.info("Mapper database info: " + Migration.DbFunction.mapperDatabaseInfo) diff --git a/obp-api/src/main/scala/code/api/util/migration/Migration.scala b/obp-api/src/main/scala/code/api/util/migration/Migration.scala index cb1c9eef89..01764bbf88 100644 --- a/obp-api/src/main/scala/code/api/util/migration/Migration.scala +++ b/obp-api/src/main/scala/code/api/util/migration/Migration.scala @@ -119,7 +119,43 @@ object Migration extends MdcLoggable { migrateConsentReferenceIdToUuid(startedBeforeSchemifier) migrateMetricConsentReferenceId(startedBeforeSchemifier) } - + + def deduplicateBeforeUniqueIndexSchemify(): Unit = { + deduplicateNaturalKeyDups( + tableName = "mapperaccountholder", + idCol = "id", + groupCols = List("user_", "accountbankpermalink", "accountpermalink") + ) + deduplicateNaturalKeyDups( + tableName = "mappedentitlement", + idCol = "id", + groupCols = List("mbankid", "muserid", "mrolename") + ) + } + + private def deduplicateNaturalKeyDups(tableName: String, idCol: String, groupCols: List[String]): Unit = { + if (DbFunction.tableExistsByName(tableName)) { + val groupBy = groupCols.mkString(", ") + val hasDups = DB.use(net.liftweb.util.DefaultConnectionIdentifier) { conn => + val st = conn.createStatement() + try { + val rs = st.executeQuery(s"SELECT 1 FROM $tableName GROUP BY $groupBy HAVING COUNT(*) > 1") + try rs.next() finally rs.close() + } finally st.close() + } + if (hasDups) { + logger.warn(s"deduplicateBeforeUniqueIndexSchemify: duplicates found in $tableName – removing extras") + DB.use(net.liftweb.util.DefaultConnectionIdentifier) { conn => + val st = conn.createStatement() + try { + st.execute(s"DELETE FROM $tableName WHERE $idCol NOT IN (SELECT MIN($idCol) FROM $tableName GROUP BY $groupBy)") + } finally st.close() + } + logger.warn(s"deduplicateBeforeUniqueIndexSchemify: dedup of $tableName complete") + } + } + } + private def dummyScript(): Boolean = { val name = nameOf(dummyScript) runOnce(name) { @@ -714,6 +750,20 @@ object Migration extends MdcLoggable { } } } + def tableExistsByName(tableName: String): Boolean = { + DB.use(net.liftweb.util.DefaultConnectionIdentifier) { conn => + val md = conn.getMetaData + val schema = getDefaultSchemaName(conn) + using(md.getTables(null, schema, null, null)) { rs => + def check(): Boolean = + if (!rs.next) false + else if (rs.getString(3).toLowerCase == tableName.toLowerCase) true + else check() + check() + } + } + } + /** * The purpose is to provide answer does a procedure exist at a database instance. */ diff --git a/obp-api/src/main/scripts/migrate/migrate_00000020.sql b/obp-api/src/main/scripts/migrate/migrate_00000020.sql deleted file mode 100644 index 0aaba786af..0000000000 --- a/obp-api/src/main/scripts/migrate/migrate_00000020.sql +++ /dev/null @@ -1,31 +0,0 @@ --- Deduplication prerequisite for the UniqueIndex additions in the concurrency-hazard fix. --- --- Background: MapperAccountHolders.dbIndexes changed from Index to UniqueIndex(user, bank, account). --- MappedEntitlement.dbIndexes added UniqueIndex(mBankId, mUserId, mRoleName). --- Lift Schemifier issues CREATE UNIQUE INDEX without a prior duplicate check; if any --- duplicate rows exist the DDL fails and the application will not start. --- --- Run this script BEFORE deploying the build that introduced these UniqueIndex additions. --- --- IMPORTANT: Verify the exact column names against your live schema before running. --- Use `\d mapperaccountholder` and `\d mappedentitlement` in psql to confirm. --- --- PostgreSQL syntax.

Read the output: The failure message for each race scenario should clearly print "expected vs actual" (e.g., "expected balance 899999...000, got 899999...XXX, lost N transfers"), the red light acts as evidence of the hazard. -3. If a scenario sporadically goes green on H2 (masked by table lock serialization), increase the concurrency N / repetition rounds, and annotate the H2 limitation in the test comments. -4. Confirm no pollution to other suites: `afterEach` cleanup + `PropsReset` pool size restoration. - -## Next Steps (Not doing now, just recording the direction) - -Fix directions (separate PR): A/B → `SELECT ... FOR UPDATE` or optimistic lock version column + state machine atomic CAS (INITIATED→PROCESSING); -C/D → Add `UniqueIndex` + application layer catches constraint conflict and returns gracefully; F → Application layer catches existing unique conflict. -The red-light tests produced by this plan will serve as the regression baseline for these fixes. diff --git a/obp-api/src/test/scala/code/concurrency/CONCURRENCY_HAZARDS.md b/obp-api/src/test/scala/code/concurrency/CONCURRENCY_HAZARDS.md index 40fd6d1e6b..7d88f9b4d2 100644 --- a/obp-api/src/test/scala/code/concurrency/CONCURRENCY_HAZARDS.md +++ b/obp-api/src/test/scala/code/concurrency/CONCURRENCY_HAZARDS.md @@ -39,6 +39,27 @@ mvn -pl obp-commons,obp-api scalatest:test \ --- +## Testing Notes — H2 Reproduction Caveats + +The test DB is in-memory H2 (`test.default.props`).

Schema evolution is handled by Lift Schemifier plus the runOnce MigrationOf* framework in Migration.scala, which supersedes these one-off scripts. Removing them keeps the migration story in one place (Migration.scala + the migration README) and avoids implying these need to be run or extended. History is preserved in git if a legacy manual upgrade path is ever needed. --- .../main/scripts/migrate/migrate_0000001.sql | 3 -- .../main/scripts/migrate/migrate_00000010.sql | 3 -- .../main/scripts/migrate/migrate_00000011.sql | 6 ---- .../main/scripts/migrate/migrate_00000012.sql | 1 - .../main/scripts/migrate/migrate_00000013.sql | 14 -------- .../main/scripts/migrate/migrate_00000014.sql | 6 ---- .../main/scripts/migrate/migrate_00000015.sql | 2 -- .../main/scripts/migrate/migrate_00000016.sql | 1 - .../main/scripts/migrate/migrate_00000017.sql | 1 - .../main/scripts/migrate/migrate_00000018.sql | 1 - .../main/scripts/migrate/migrate_00000019.sql | 3 -- .../main/scripts/migrate/migrate_0000002.sql | 2 -- .../main/scripts/migrate/migrate_0000003.sql | 2 -- .../main/scripts/migrate/migrate_0000004.sql | 34 ------------------- .../main/scripts/migrate/migrate_0000005.sql | 1 - .../main/scripts/migrate/migrate_0000006.sql | 2 -- .../main/scripts/migrate/migrate_0000007.sql | 6 ---- .../main/scripts/migrate/migrate_0000008.sql | 7 ---- .../main/scripts/migrate/migrate_0000009.sql | 2 -- 19 files changed, 97 deletions(-) delete mode 100644 obp-api/src/main/scripts/migrate/migrate_0000001.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_00000010.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_00000011.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_00000012.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_00000013.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_00000014.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_00000015.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_00000016.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_00000017.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_00000018.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_00000019.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_0000002.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_0000003.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_0000004.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_0000005.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_0000006.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_0000007.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_0000008.sql delete mode 100644 obp-api/src/main/scripts/migrate/migrate_0000009.sql diff --git a/obp-api/src/main/scripts/migrate/migrate_0000001.sql b/obp-api/src/main/scripts/migrate/migrate_0000001.sql deleted file mode 100644 index 0b5365c5bf..0000000000 --- a/obp-api/src/main/scripts/migrate/migrate_0000001.sql +++ /dev/null @@ -1,3 +0,0 @@ -alter table mappedbankaccount alter column accuuid type varchar(80);

WHERE id NOT IN (SELECT MIN(id) FROM sameTable GROUP BY ...). That survivor-set form names the target table inside the DELETE subquery, which MySQL/MariaDB reject with ERROR 1093, and it scales with table size rather than with the number of duplicates. MySQL is a first-class OBP target (driver shipped, per-vendor SQL branches throughout this package), so the form could abort boot on a MySQL deployment while passing on H2/Postgres. Switch to a delete-set form: a derived table over ROW_NUMBER() OVER (PARTITION BY ORDER BY id ASC) that targets only the surplus rows. The derived table is materialised, which sidesteps 1093, and window functions are supported by every driver OBP ships (PostgreSQL, H2 2.x, MySQL 8+/MariaDB 10.2+, SQL Server, Oracle). The survivor is unchanged: the lowest id per natural-key group. Also replace execute() with executeUpdate() so the destructive cleanup logs how many rows it removed, and document the lossy survivor policy: discarded duplicates' mentitlementid UUIDs and provenance columns are dropped, while the surviving row still encodes the same grant/ownership. Verified the new SQL on H2 2.2.220 (the shipped version): it keeps the lowest id per group, including for NULL partition keys. --- .../code/api/util/migration/Migration.scala | 47 +++++++++++++++++-- 1 file changed, 43 insertions(+), 4 deletions(-) diff --git a/obp-api/src/main/scala/code/api/util/migration/Migration.scala b/obp-api/src/main/scala/code/api/util/migration/Migration.scala index 2a2ec62d84..95853d132f 100644 --- a/obp-api/src/main/scala/code/api/util/migration/Migration.scala +++ b/obp-api/src/main/scala/code/api/util/migration/Migration.scala @@ -182,6 +182,29 @@ object Migration extends MdcLoggable { ) } + /** + * Collapse natural-key duplicates in `tableName` down to one surviving row per key group. + * + * Survivor policy: KEEP the row with the lowest `idCol` (the oldest insert) per `groupCols` + * group, DELETE the rest.

The + * surviving row encodes the same (user, account) ownership link. + * + * Safe to run on every boot and under concurrent multi-node boot: the survivor set is a + * deterministic lowest-id-per-group, the DELETE is idempotent (re-running removes 0 rows), and + * Lift Mapper's Schemifier emits no DB-level FK constraints, so the DELETE neither cascades nor + * aborts on referential integrity. The has-duplicates probe keeps clean/fresh/test DBs on the + * cheap path — the heavier delete only runs when extras actually exist.
