From 19cc2e19a5732fd1dc15ab80424cb95f75e719f5 Mon Sep 17 00:00:00 2001 From: fabrizzio-dotCMS Date: Mon, 27 Jul 2026 11:29:20 -0600 Subject: [PATCH] feat(review): add the Java backend reviewer agent to /dot-review Introduces the `dotcms-java-backend-reviewer` agent definition and the `/dot-review` PR review command that dispatches it, so backend Java changes get reviewed against the project standards documented in CLAUDE.md and docs/backend/. The agent reports only evidence-backed findings with confidence >= 75, banded Critical/Important/Quality, and each rule carries its own "how to apply without false positives" guidance. Two rules in this first revision are worth calling out because both fail silently in ways Java-level tests do not catch: - Commit listeners: work that must only run if a preceding persistence operation succeeded belongs in HibernateUtil.addCommitListener, and data that only exists after commit must be read inside the listener body. Registering outside an open transaction runs the listener inline, and on rollback it never runs at all. - Records reaching VTL: dotCMS forks Velocity 1.7 in-tree and its introspection resolves $obj.foo through getFoo()/getfoo()/get("foo")/ isFoo() only, never a record's foo() accessor. With runtime.references.strict=false the reference renders as literal text, so a record replacing a getter-based type on the Velocity context breaks templates while the build stays green. The skill also documents which subagent types actually exist in the repo, so the command falls back to inline review instead of dispatching agents that are not committed yet.

Cite the file:line and quote the offending code. + +### Critical project rules (usually 🔴) +- **Config/Logger only**: flag any `System.out`, `System.err`, `System.getProperty`, or `System.getenv`. Must use `Config.getStringProperty(...)` / `Logger.info(this, ...)`. +- **Maven versions**: new/changed dependency `` must live in `bom/application/pom.xml` ONLY — never inline in `dotCMS/pom.xml` or other module POMs. +- **REST `@Schema`**: the declared `@Schema` / `@ApiResponse` type must match the method's actual return type. A mismatch is a broken API contract. (Endpoint documentation completeness — `@Operation`/`operationId`/`@Parameter` — has its own section below.) +- **OpenAPI drift**: if JAX-RS annotations (`@Operation`, `@Parameter`, `@Path`, response types) changed but `src/main/webapp/WEB-INF/openapi/openapi.yaml` was NOT regenerated/committed in the same PR, flag it — CI verifies the committed yaml matches the build. +- **Security**: hardcoded secrets/credentials, unvalidated external input reaching queries/filesystem/index calls, or logging of sensitive data (passwords, tokens, PII). +- **Java version**: don't introduce APIs below the module's compile target without reason; core modules compile to Java 25. + +### Important patterns (usually 🟡) +- **Service access**: use `APILocator.getXxxAPI()` rather than `new`-ing up API implementations. +- **Permission checks**: per-item `permissionAPI.doesUserHavePermission(...)` inside a loop over a collection should be `permissionAPI.filterCollection(Collection, int, User, boolean)` — one SQL round-trip vs N. +- **Exceptions**: swallowed exceptions (empty catch, catch-and-log-and-continue that hides failure), or throwing raw `Exception`/`RuntimeException` where a `Dot*Exception` exists. +- **Transactions / DB**: `DotConnect` usage without parameterization (SQL injection / correctness), or DB writes outside the expected transactional boundary. +- **Null handling**: dereferencing values from APIs known to return null without an `UtilMethods.isSet(...)` / null guard. + +### `respectFrontendRoles` — front-end role semantics (dotCMS-specific) + +Many dotCMS APIs (ContentletAPI, HostAPI, FolderAPI, PermissionAPI, HTMLPageAssetAPI, etc.) take a trailing `boolean respectFrontendRoles` (a.k.a. "respect front-end roles"). It controls whether the **CMS Anonymous** role and the **Logged-in Site User** role are included when evaluating permissions (see `PermissionBitAPIImpl.filterUserRoles` and `doesUserHavePermissionInternal`): + +- `true` → those front-end roles are kept, so anonymous/front-end visitors can be granted access (e.g. reading a **live** contentlet the Anonymous role can see). This is the **front-end content-delivery** semantic (page/velocity rendering in LIVE mode uses it). +- `false` → the Logged-in Site User, CMS Anonymous, and `anonymous` roles are stripped from the effective role set, so access is decided **only** by the user's real back-end roles. + +**General rule to enforce:** back-end / internal **system functionality** — anything that is not serving content to a site visitor (admin REST endpoints, indexing/reindex, migration, validators, background jobs, internal lookups of hosts/folders/content by system logic) — should pass **`false`** (`Constants.DONT_RESPECT_FRONT_END_ROLES`). Passing `true` there can silently widen the effective permission set through the Anonymous role and leak access. Front-end delivery paths (rendering live pages/content for visitors) legitimately pass `true`. + +How to apply without false positives: +- 🟡/🔴 Flag a **`true`** (or `RESPECT_FRONT_END_ROLES` / `RESPECT_FRONTEND_ROLES`) on a limited/end-user in clearly internal/system or admin-only backend code — escalate to 🔴 when it feeds a permission decision on a security-sensitive path. Explain that it can grant access via the CMS Anonymous role. +- Do NOT flag calls made as `APILocator.systemUser()` / an admin user solely on this basis: `doesUserHavePermissionInternal` short-circuits to `true` for system user and admins *before* the flag is consulted, so the value is functionally irrelevant there (passing `false` is still the idiomatic, defensive default). +- Do NOT flag front-end delivery/rendering code that intentionally respects anonymous permissions (LIVE-mode page/content serving, `params.mode.respectAnonPerms`). +- 🔵 Flag hardcoded boolean literals for this argument where `Constants.RESPECT_FRONT_END_ROLES` / `Constants.DONT_RESPECT_FRONT_END_ROLES` (or `ContentMappingAPI.RESPECT_FRONTEND_ROLES` / `DONT_RESPECT_FRONTEND_ROLES`) would make intent explicit. + +### `@WrapInTransaction` / `@CloseDBIfOpened` — DB lifecycle annotations (dotCMS-specific) + +These two annotations (package `com.dotcms.business`) own the JDBC connection/transaction lifecycle for a method. Both are applied to `METHOD`/`TYPE` and fire either via ByteBuddy load-time advice (plain classes, e.g. most `*APIImpl`) or the CDI interceptor (managed beans). Validated semantics: + +- **`@CloseDBIfOpened`** (read semantic): on enter records whether a connection already existed; on exit (normal **or** exceptional) closes the connection **only if this method opened it**. It does **not** start a transaction and does **not** commit/rollback. If an outer scope already owns a connection/transaction, it leaves it untouched. Attribute `connection=false` disables the close. +- **`@WrapInTransaction`** (write semantic): starts a *local* transaction only if none is active; if a transaction is already open it **joins** it (REQUIRED-style propagation) and lets the outermost owner commit/close. On success it commits; on **any `Throwable`** escaping the method it **rolls back**; on finally it closes the connection if it opened it. Attribute `externalize=true` forces a new transaction. + +**Rules to enforce:** + +- **Pick by intent** 🟡: read-only methods (`find*`, `get*`, `search*`, `load*`, counts) → `@CloseDBIfOpened`. Mutating methods (`save`, `delete`, `update`, `insert`, `publish`, `unpublish`, multi-step writes) → `@WrapInTransaction`. A method that performs writes but is annotated only `@CloseDBIfOpened` (or nothing) has **no atomicity / no rollback** — flag it. This is the most important misuse to catch. +- **Rollback is exception-driven** 🔴/🟡: inside a `@WrapInTransaction` method, swallowing an exception that should abort the write (empty catch, catch-log-and-continue) causes the transaction to **commit partial work**. If you catch, rethrow (a `Dot*Exception`) so rollback fires. Flag swallowed exceptions on the write path. +- **Don't stack both on the same method** 🟡: `@WrapInTransaction` already closes a new connection in its finally block, so `@CloseDBIfOpened` + `@WrapInTransaction` together is redundant and semantically muddy — flag it (a known smell in the codebase). +- **No manual lifecycle inside an annotated method** 🟡/🔴: don't manually `DbConnectionFactory.getConnection()` + `close()`/`commit()`/`rollback()` or `DbConnectionFactory.closeSilently()` inside a `@WrapInTransaction`/`@CloseDBIfOpened` method — the annotation owns the connection; manual close/commit breaks the managed boundary (can commit early, close a connection the outer scope still needs, or leak). **Recognizable symptom:** at commit time dotCMS checks that the connection which started the transaction is still the current one (`LocalTransaction.handleTransactionInteruption` / `CoreTransactionOps`); if the original connection was closed and a new one opened mid-transaction it emits **"Transaction broken - Connection that started the transaction is not the same as the one who is commiting"** (logged by default, or thrown as `DotDataException` when `LOCAL_TRANSACTION_INTERUPTED_ACTION=THROW`). Seeing/expecting this message is a strong signal of exactly this misuse — flag the manual close/commit that caused it. +- **Nesting is fine, relying on a read method to persist is not** 🟡: nested annotated calls share the outer transaction. But a `@CloseDBIfOpened` method never commits, so writes performed under only that annotation (with no enclosing `@WrapInTransaction`) are not guaranteed durable/atomic. +- **Interception boundary** 🔵/🟡: prefer annotating **public** entry points. For CDI-managed beans, a `private`/`protected` method or a `this.method()` self-invocation **bypasses** the interceptor, so the annotation silently does nothing. Flag annotations on private methods or transactions expected to start via a self-call — but note this caveat does not apply to ByteBuddy load-time-instrumented plain classes, so don't hard-fail without checking the class type. +- **Large batches: prefer manual chunked commits over one wrapping transaction** 🟡: do **not** wrap a loop that processes many elements (imports, migrations, mass reindex/publish, bulk cleanup jobs) in a single `@WrapInTransaction`. One transaction over thousands of rows holds locks for the whole run, grows the undo/redo and the Hibernate session unboundedly, and in practice **never commits or hangs** on large inputs. The dotCMS idiom is **manual, chunked** transaction control: run `HibernateUtil.startTransaction()` … process a chunk … `HibernateUtil.closeAndCommitTransaction()` and start the next one, committing every N items (a *commit granularity* / batch size). Canonical example: `ImportUtil` commits every `commitGranularityOverride()` successful rows via `handleBatchCommit(...)`. So for a bulk method, flag a single all-encompassing `@WrapInTransaction` and recommend per-chunk manual commits instead. + - This is the **legitimate exception** to the "no manual lifecycle" rule above: manual `HibernateUtil` transaction control is correct in a bulk/batch context and must NOT be flagged there. The "no manual lifecycle" rule applies to mixing manual close/commit **inside** an `@WrapInTransaction`/`@CloseDBIfOpened` method — the batch method should own its transactions manually and simply not carry those annotations. Keep per-chunk failures scoped so one bad chunk doesn't silently abort the rest (or is reported), matching the batch semantics the code intends. + +How to apply without false positives: +- Confirm the method actually touches the DB before demanding an annotation (pure computation / delegation-only methods need none). +- Don't flag an unannotated method whose only DB work is delegated to already-annotated API calls — the transaction is owned downstream. +- `connection=false` / `externalize=true` are deliberate escape hatches; flag only when used without a clear reason, not on sight. + +### Commit listeners — chain post-persistence work to the commit (dotCMS-specific) + +A **commit listener** (`com.dotmarketing.db.HibernateUtil.addCommitListener(...)`) exists to chain a relevant operation that **must only happen if a preceding persistence operation succeeded**. Verified semantics: + +- Registration (`addCommitListener(Runnable)` / `(String tag, Runnable)` / `(Runnable, int order)` / `addCommitListenerNoThrow(...)` / `addSyncCommitListener(...)`) only **queues** the listener when `DbConnectionFactory.inTransaction()` is true and the thread's `TransactionListenerStatus != DISABLED`. Listeners fire from `finalizeCommitListeners()` **after** `connection.commit()` (on `closeAndCommitTransaction` / `closeSession`). +- On **rollback** the listener maps are cleared without running — that is exactly the "only if the write succeeded" guarantee. +- **If there is no open transaction, the listener runs IMMEDIATELY, inline** (`else { listener.run(); }`) — the post-commit contract silently degrades to "right now". +- **Async listeners** (the default for a plain `Runnable`) run on a **different thread** via the `DotConcurrentFactory` listener submitter, *after* the transaction's connection was closed: they do **not** share the connection/session/thread-locals, and any DB read inside them opens a new connection that sees the committed data. **`addSyncCommitListener(...)`** (`DotSyncRunnable`) runs on the main dotCMS thread and can still see connection/session-scoped state (temp tables). `FlushCacheRunnable` is routed to the cache-flusher lane (run twice, with `NETWORK_CACHE_FLUSH_DELAY`, for cluster propagation); `ReindexRunnable` has its own async/sync switch. +- `addCommitListener(tag, ...)` keys the listener by tag: re-registering the same tag inside one transaction **collapses to a single execution** (dedup/idempotency); the no-tag overloads generate a UUID, so every registration runs. +- `addRollbackListener(...)` is the mirror hook for compensating an eager side effect; it is silently dropped when no transaction is open. + +**Rules to enforce:** + +- **Non-transactional side effect that depends on a write must move into a commit listener** 🔴/🟡: when the PR performs a persistence operation and then, in the same transactional scope, executes a follow-up whose effect is **not covered by the rollback** — index add/remove, cache invalidation, System/Local event notification (`localSystemEventsAPI.notify`, websocket/SSE push), push-publish queue send, workflow/job scheduling, e-mail or external HTTP call, asset-store file move/delete, spawning a thread — flag it and require `HibernateUtil.addCommitListener(...)`. If the transaction later rolls back, the DB is clean but that side effect already happened: the index, cache, external system or file system now describe data that does not exist. Escalate to 🔴 when the divergence is persistent (index/DB drift, a deleted binary whose row survived, another system told about a row that never committed) or when the follow-up is itself a **write that presumes the first write's success**; 🟡 when the effect is transient/recoverable (a stale notification, a cache entry that self-heals). +- **Order dependency ⇒ make it explicit** 🟡: when operation B is only correct *after* A committed, do not rely on statement order inside the method. Register B as a commit listener; when two listeners depend on each other's effects, use the ordering overload `addCommitListener(runnable, order)` / `DotOrderedRunnable` instead of registration order (listeners are sorted by `order`, and async/sync/flusher lanes run separately). +- **Read data that only exists after commit inside the listener body** 🔴/🟡: if the follow-up needs rows/state that are only visible post-commit — a re-read by identifier/inode, a query from **another connection or thread** (async listener, submitted job, external service calling back, cluster node), a search-index read, anything that must observe the committed row — the **read must be performed inside the listener**, not captured before registration. Flag both failure directions: (a) a value read/computed **before** the write and closed over by the lambda, so the listener acts on a pre-commit snapshot; (b) a listener that hands a fresh-read expectation to code running on another thread while the read actually happened in the transaction. Conversely, if the follow-up genuinely needs connection/session-scoped state from the transaction (a temp table, `DbConnectionFactory.getConnection()` state), it must be `addSyncCommitListener(...)` — an async listener will not see it. +- **Registered outside a transaction is a no-op guarantee** 🟡: flag a commit listener registered in a method with no `@WrapInTransaction` (and no enclosing transactional caller) while the code clearly relies on post-commit ordering — it will run inline, before any commit, defeating the point. Verify the enclosing boundary before flagging. +- **A commit listener cannot abort the write** 🟡: the transaction is already committed when the listener runs, so an exception thrown inside it does **not** roll anything back (async listeners just log on their own thread). Flag (a) validation or a precondition check moved into a listener as if it could veto the write, and (b) a listener body with no error handling for work that must not be lost silently — it should log/report and be idempotent/retryable. If a side effect truly has to run eagerly, pair it with `addRollbackListener(...)` to compensate. +- **Use the right listener flavor / a stable tag** 🔵/🟡: cache invalidation belongs in a `FlushCacheRunnable` (gets the double flush + cluster delay), not a plain lambda calling `cache.remove(...)`. When the same post-commit action can be registered many times in one transaction (per item in a loop), pass a **stable tag** so it collapses to one execution — and conversely, watch for an unintended tag collision that drops a listener that should have run per item. +- **Async listener bodies must not depend on thread-local context** 🟡: they execute on a pooled thread after the request/transaction ended, so `HttpServletRequestThreadLocal`, the transaction's connection, the current-user thread-local and similar are gone. Flag an async listener that reads them; capture the needed values (user, ids, request-derived data) into effectively-final locals before registering, or use `addSyncCommitListener`. + +How to apply without false positives: +- **Pure DB work does not need a listener.** Follow-up SQL inside the same transaction is already atomic with the first write — moving it to a commit listener would actually *lose* atomicity (it would run on a new connection, outside the transaction). This rule targets side effects the rollback cannot undo. +- Code already inside a listener body, or already after an explicit `HibernateUtil.closeAndCommitTransaction()` in the manual/chunked batch pattern, satisfies the rule — don't double-flag. +- Work that must deliberately happen **before** commit (validation, populating related rows, computing values the write needs) is correct where it is. +- Don't flag untouched legacy call sites that merely appear in context; only lines the PR adds/changes. Tests, one-shot startup/upgrade tasks and clearly non-transactional utilities are out of scope. +- Before flagging, confirm the follow-up really escapes the transaction (grep the callee if needed): many dotCMS APIs already register their own commit listener internally (e.g. reindex paths), and wrapping an already-deferred call in a second listener is not an improvement. + +### Distributed file-system access — minimize disk I/O (dotCMS-specific) + +dotCMS runs its asset store on a **distributed / networked file system** (see `com.dotcms.storage`: `StoragePersistenceAPI` with FileSystem/S3/DB/Redis backends). Every direct `java.io.File` operation — `exists()`, `length()`, `lastModified()`, `new File(path)` stat, opening a stream — is a **network round-trip** that is far more expensive than a local disk call and can **block the calling thread** (read locks / thread starvation under load). The changed code should touch disk as little as possible. + +**Rules to enforce:** + +- **No repeated / defensive `file.exists()` (and friends)** 🟡: flag `exists()`, `length()`, `lastModified()`, or `canRead()` called in loops, on hot request paths, or as a pre-check before an operation that would reveal absence anyway (e.g. `if (f.exists()) { read(f) }` where the read already handles the missing case). Each call is a separate round-trip. Attempt the operation and handle the failure, or consult the metadata cache once. +- **Prefer the cached Metadata API over statting the file** 🟡: to obtain file facts (existence, size, SHA-256, content type, dimensions, path), use `FileMetadataAPI.getMetadata(...)` / `getOrGenerateMetadata(...)` — these are **cache-backed** (see `Chainable404StorageCache`) — instead of constructing a `File` and reading attributes off disk. The `Metadata` object already carries size/sha256/contentType/etc. Explicitly flag new uses of `getFullMetadataNoCache(...)` / `getOrGenerateFullMetadataNoCache(...)` on a request path, since those **bypass the cache and hit disk by design** — acceptable only when fresh-from-disk data is genuinely required. +- **Read the binary only to deliver it** 🟡: open/stream a file's bytes only when the purpose is to actually serve or process its content — never to "check" something that metadata can answer. Don't read a whole file to compute a hash/size the metadata already has. +- **Don't stat inside tight loops over many assets** 🔴/🟡: a per-item `File` stat inside a loop over many contentlets/assets multiplies round-trips; batch via metadata or restructure. Escalate when the loop is unbounded or on a user-facing path. + +How to apply without false positives: +- A single `exists()`/stat at a true entry point (validating a user-supplied path, a startup/upgrade task, a one-shot admin action) is fine — don't flag one-off checks off the hot path. +- Local temp-file / `TempResource` handling and unit/integration test code are not the distributed asset store — exempt. +- Don't demand the Metadata API where it doesn't apply (files outside the asset store, config files read once at boot). + +### `Config.getProperty(...)` in hot paths — cache the value (dotCMS-specific) + +`Config.getStringProperty/getBooleanProperty/getIntProperty(...)` (`com.dotmarketing.util.Config`) is **not free**: it resolves against an Apache `PropertiesConfiguration` and is backed by a file-watcher that can reload. Calling it **inside a loop** or on every request of a hot path is wasteful — the value almost never changes between iterations. + +**Rules to enforce:** + +- **No `Config.get*Property(...)` inside a loop** 🟡: flag a `Config` read whose key/args are loop-invariant called inside a `for`/`while`/stream over many items. Hoist it to a local variable **before** the loop (or to a field). Escalate on large/unbounded loops or request-hot paths. +- **Prefer caching for repeatedly-read properties** 🔵/🟡: for a property read many times over an object's life, cache it instead of re-reading each call. Two accepted idioms in this codebase: + - `private static final Lazy KEY = Lazy.of(() -> Config.get...(...));` (`io.vavr.Lazy`) — the widespread pattern. **Caveat to call out:** `Lazy` resolves once and **freezes** the value, so the property can no longer be changed at runtime. Only fine when the property is effectively static for the process. + - Read once in the **constructor** and store in a field — use this when the value should be fixed for the object's lifetime but you don't want a static/global cache. +- **When runtime-changeability matters, don't over-cache** 🔵: if a property is genuinely meant to be tunable live (feature flags toggled by ops), a per-call `Config` read is intentional — do not flag it, and do not recommend `Lazy` there (it would defeat the live toggle). Judge by whether the key looks like a live-tunable flag vs a static tuning constant. + +How to apply without false positives: a single `Config` read once per method call (not in a loop) is usually fine — don't demand caching everywhere. Focus on loop-invariant reads and clearly hot paths. + +### Integration-test suite registration (dotCMS-specific) + +dotCMS integration tests only run in CI if they are **registered in a JUnit suite** (`@SuiteClasses({...})`); an IT class that no suite references is silently never executed. This applies to added/renamed backend Java test classes under `dotcms-integration/`. + +**Rules to enforce:** + +- **New/renamed integration test must be added to a suite** 🟡: if the PR adds a `*IT.java` class under `dotcms-integration/src/test/java` but does not add it to a suite's `@SuiteClasses` list, flag it — it will not run. The suite must match the test's nature: + - OpenSearch / ES→OS migration ITs → `OpenSearchUpgradeSuite`. + - General ITs → one of `MainSuite1a` / `MainSuite1b` / `MainSuite2a` / `MainSuite2b` / `MainSuite3a`. + - Fast/smoke ITs → `QuickSuite`. +- **Naming/location** 🔵: integration tests live in `dotcms-integration` and the class name ends in the literal suffix `IT` (so Failsafe picks them up). Flag an integration test named `*Test` or placed outside `dotcms-integration`. +- **Pure unit tests must NOT be added to an integration suite** 🔵/🟡: a fast unit test (no container/DB/ES) belongs to Surefire via the `*Test` suffix and should **not** be registered in an integration `@SuiteClasses` list. Flag a unit test wired into a suite (it slows the integration battery) or an integration test misnamed `*Test`. + +How to apply without false positives: only raise this when the PR actually adds or renames a test class; don't demand suite membership for edits to an already-registered test. If the diff shows the class being added to a suite in the same PR (as `MainSuite2b` edits often accompany a new IT), it's satisfied — confirm before flagging. + +### Input, query & file-name security (dotCMS-specific) + +Untrusted input (REST params/bodies, headers, uploaded files, VTL-reachable values) must be validated/sanitized before it reaches a query, the file system, or a response. Prefer the existing dotCMS helpers over hand-rolled checks. + +**Rules to enforce:** + +- **No user input concatenated into SQL / Lucene** 🔴: flag string-built queries with request data — `new DotConnect().setSQL("... where x = '" + userValue + "'")`, string-formatted `ES`/Lucene queries, or interpolated HQL. Use **bound parameters**: `?` placeholders + `DotConnect.addParam(...)` / `addObject(...)`. This is the top injection risk; escalate to 🔴 when the tainted value is clearly external. +- **Sanitize uploaded / user-supplied file names** 🔴/🟡: a file name coming from an upload, header (`Content-Disposition`), or request param must be sanitized with `FileUtil.sanitizeFileName(...)` before being used as a path segment or persisted. Flag raw use of `part.getFileName()` / `getSubmittedFileName()` / a request-supplied name written to disk without sanitizing. +- **Guard against path traversal** 🔴: any path assembled from user input must reject `..`, absolute paths, and double slashes — use `FileUtil.isValidFilePath(...)` and/or `Path.normalize()` + a base-dir containment check (see `DotTempFile` `normalize()` pattern). Flag `new File(baseDir, userSuppliedPath)` or `Paths.get(userInput)` with no traversal guard. +- **Encode output to prevent XSS** 🟡: values echoed into HTML/JS/URL responses should be encoded with the OWASP-based helpers already in the codebase (`OwaspEncoderTool`, `XssWebAPI`, `com.liferay.util.Xss`) rather than concatenated raw. Flag raw reflection of request input into a markup/script response. +- **Validate before trusting** 🟡: enum/id/type params from the request should be validated (whitelist / `Enum.valueOf` in a guarded block) before use; numeric/limit/offset params should be range-checked. Flag unchecked casts of request strings into query fragments, reflection targets, or class names. +- **Log security events, never secrets** 🔵/🟡: use `SecurityLogger` for rejected/suspicious input (the file/path helpers already do); never log passwords, tokens, or full request bodies containing credentials. + +How to apply without false positives: +- Don't flag internally-generated values (a system-built inode, a constant, an already-validated identifier) as if they were tainted — trace whether the value actually originates from the request. +- `DotConnect` calls with only literal/constant SQL and no interpolation are fine. +- Don't demand `sanitizeFileName` on names that are already dotCMS identifiers or came from a trusted lookup, only on raw user/upload input. + +### REST endpoint documentation — annotate for OpenAPI & AI-agent consumption (dotCMS-specific) + +`openapi.yaml` is auto-generated from the JAX-RS + Swagger annotations, and it is consumed by AI agents / the MCP server. An undocumented or vaguely documented endpoint is effectively unusable by an agent (it can't tell what the operation does or how to call it). Every new/changed REST endpoint must carry meaningful annotations. + +**Rules to enforce (on added/changed endpoints):** + +- **`@Operation` with a real summary AND description** 🟡: every JAX-RS handler (`@GET`/`@POST`/`@PUT`/`@DELETE`/`@PATCH`) added or materially changed by the PR must have `@Operation` with a concise `summary` and a `description` that states what it does, when to use it, and notable behavior. Flag a new endpoint with no `@Operation`, or with an empty/placeholder/one-word description. Descriptions written for a human *and* an agent (inputs, effects, preconditions) are the goal — not "Gets the page." +- **Stable `operationId`** 🟡: set an explicit, descriptive `operationId` (e.g. `getPageRenderByUri`) — agents key off it. Flag a missing `operationId` on a new endpoint, and flag an `operationId` change on an existing endpoint (it breaks generated clients/agent bindings) unless the PR clearly intends the rename. +- **`@Parameter` descriptions** 🔵/🟡: each path/query/header param should have `@Parameter(description = "...")`. Flag new params with no description. +- **`@ApiResponse` + `@Schema` on the payload** 🟡: document the success response (and meaningful error codes) with `@ApiResponse`, and give the return/body type an accurate `@Schema`. For `type = "object"` / `Map` / JSON responses, a `description` is **required** (per the REST module's AI-specific `@Schema` rules) — flag `type="object"` with no description, and never `@Schema(implementation = Object.class/Map.class/HashMap.class)` (use a specific view class or `type="object"` + description). +- **Regenerate the yaml** 🔴: annotation changes must be accompanied by the regenerated `src/main/webapp/WEB-INF/openapi/openapi.yaml` in the same PR (this overlaps the OpenAPI-drift rule above). + +How to apply without false positives: +- Only require this on endpoints the PR **adds or changes** — don't demand full annotations on untouched neighboring methods. +- Internal/non-REST methods, private helpers, and JAX-RS sub-resource locators that aren't themselves operations don't need `@Operation`. +- A minor body change to an already-well-documented endpoint doesn't need new annotations — judge whether the contract/behavior actually changed. + +### Never mutate a cache-returned `Contentlet` in place (dotCMS-specific) + +A `Contentlet` returned by the APIs (`ContentletAPI.find/findContentletByIdentifier/search/checkout...`) is frequently the **same instance that lives in the content cache**, shared across threads. Mutating it directly — `setProperty`/`setStringProperty`/`setInode`/`setLanguageId`/`setBoolProperty`, or `getMap().put(...)`/`remove(...)` — **corrupts the cached object** for every other caller, causing intermittent, hard-to-reproduce bugs (wrong field values, phantom state, cross-request bleed). + +**Rule to enforce:** + +- **Copy before mutate** 🔴/🟡: if the PR takes a Contentlet obtained from an API and then mutates it, flag it and require a defensive copy first. The dotCMS idiom is the map-based copy: + ```java + final Contentlet copy = new Contentlet(original.getMap()); // copy constructor putAll's a fresh ContentletHashMap + // ...mutate `copy`, not `original` + ``` + or `newContentlet.getMap().putAll(original.getMap());`. Then perform the mutations/`checkin` on the copy. Escalate to 🔴 when the mutated instance clearly came straight from a cache-backed `find`/`search` and is written back or shared. + +How to apply without false positives: +- A Contentlet the code **just constructed itself** (`new Contentlet()`, `ContentletDataGen`, a builder, or a copy already made) is safe to mutate — only flag mutation of instances **returned by an API/cache**. +- `checkout(...)` returns a working copy intended for editing in some flows — don't blanket-flag; check whether the specific API contract hands back a mutable copy vs the cached instance. +- Read-only access (`get*`, reading `getMap()` values) is fine — the rule is about **writes** to a shared instance. + +### Page API: keep REST and GraphQL responses equivalent (dotCMS-specific) + +dotCMS exposes the Page API through **two surfaces that are meant to return equivalent shapes**: the REST Page API and the GraphQL Page API. If the PR changes what the REST page response contains, the GraphQL page response must change to match (and vice versa) — otherwise the two drift and clients that switch surfaces get different data. + +- REST side: `PageResource` and the page view model — `PageView` / `PageViewSerializer` / `EmptyPageView` / `HTMLPageAssetRendered(Builder)` under `com.dotmarketing.portlets.htmlpageasset.business.render.page`, plus `PageViewStrategy`. +- GraphQL side: `com.dotcms.graphql.business.PageAPIGraphQLTypesProvider`, `PageAPIGraphQLFieldsProvider`, and the `com.dotcms.graphql.datafetcher.page` fetchers (`PageDataFetcher`, `PageRenderDataFetcher`). + +**Rule to enforce:** + +- **Mirror page-response changes across both surfaces** 🟡: if the PR adds, removes, renames, or changes the type/meaning of a field in the REST page response (`PageView`/`PageViewSerializer`/etc.), verify the equivalent change also lands in the GraphQL page providers/fetchers — and vice versa. If only one surface changed, flag the missing counterpart. Use Grep to confirm whether the GraphQL page files are also modified in this PR before flagging. + +How to apply without false positives: +- Only raise this when the **response shape/contract** changes, not for internal refactors, logging, or performance changes that leave the emitted fields identical. +- A field may be intentionally exposed on only one surface; if the PR/description says so or the field is clearly surface-specific (e.g. a REST-only HATEOAS/link block, or a GraphQL-only resolver convenience), don't force parity — note it as a question rather than a hard finding. +- This applies specifically to the **Page API**; don't generalize it to unrelated endpoints that have no GraphQL equivalent. + +### Audit-log sensitive-resource changes via SecurityLogger (dotCMS-specific) + +Modifications to security-sensitive resources — **Apps / app secrets**, permissions/roles, users, API tokens, licenses, portlet/tool access — must leave an audit trail identifying **who** performed the change. dotCMS provides `SecurityLogger` (static, `com.dotmarketing.util.SecurityLogger`) and the injectable `SecurityLoggerServiceAPI` (`APILocator.getSecurityLogger()`); the Apps layer (`AppsHelper`) is the reference pattern. + +**Rule to enforce:** + +- **Log sensitive mutations with the acting user** 🟡: when the PR adds/changes code that creates, updates, or deletes a sensitive resource (especially Apps secrets), verify it emits a `SecurityLogger` / `securityLoggerAPI.logInfo(...)` entry that records the **acting user** and the **resource/action** — mirroring the established idiom: + ```java + securityLoggerAPI.logInfo(this.getClass(), + String.format("User `%s` updated secret for app `%s` on host `%s`", user, key, host.getIdentifier())); + ``` + Flag a new sensitive-resource mutation path with no security-log entry, or one that logs the action but **omits who did it** (no user id). +- **Don't log the secret value** 🔴: the audit line records *who/what/which resource*, never the secret/credential value itself. Flag any security log (or ordinary `Logger`) that includes the secret payload. (Apps code calls `destroySecretTraces()` for this reason.) + +How to apply without false positives: +- Scope to genuinely sensitive resources (Apps/secrets, permissions, users/roles, tokens, licenses) — don't demand a security log for ordinary content edits (those have their own history) or read-only access. +- Use `SecurityLogger`/`SecurityLoggerServiceAPI`, not plain `Logger`, for the audit entry — but if the surrounding class already funnels these through a wrapper, match the local convention. + +### PostgreSQL is the only supported database — don't add other-engine code (dotCMS-specific) + +dotCMS **no longer supports any SQL engine other than PostgreSQL** (legacy MySQL/Oracle/SQL Server support is being retired). New code must not add branches or dialect-specific SQL for other engines. The legacy engine-detection helpers `DbConnectionFactory.isOracle()` / `isMsSql()` / `isMySql()` / `getDBType()` still exist and are used in ~hundreds of legacy sites — but new code should not extend that pattern. + +**Rule to enforce (on code the PR adds):** + +- **No new non-Postgres engine branches** 🟡: flag newly-added `if (DbConnectionFactory.isOracle()/isMsSql()/isMySql())` branches, Oracle/MySQL/MSSQL-specific SQL dialect strings, or per-engine SQL maps introduced by the PR. Write the SQL once for PostgreSQL. +- **`isPostgres()` guards are usually redundant in new code** 🔵: since Postgres is the only engine, a new `if (isPostgres()) {...}` wrapper is dead conditional complexity — note it, but low priority. + +How to apply without false positives: +- Only flag **new** other-engine code the PR introduces — do NOT flag the ~666 existing legacy branches; untouched legacy multi-DB code is out of scope. +- Removing/simplifying existing non-Postgres branches is welcome, not a finding. +- Postgres-specific SQL/features (JSONB, `ON CONFLICT`, etc.) are fine and encouraged. + +### Wrap third-party libraries behind a dotCMS abstraction (anti-corruption layer) + +When the PR introduces or adopts a third-party library, dotCMS code should depend on a **dotCMS-owned abstraction** (interface + DTO) that retrieves/serves the values, not on the library's concrete types directly. The library's objects should not leak into API signatures, cached/persisted objects, cross-module contracts, or REST/GraphQL responses. This is the same principle driving the ES→OS migration: vendor-neutral types like `com.dotcms.content.index.domain.ContentSearchResponse` / `SearchHit` / `Aggregation` replace Elasticsearch-specific classes so the store can be swapped without touching callers. + +**Severity note:** this is a **good-practice signal, not a blocker**. Its purpose is to *make visible* that the PR is creating a dependency/coupling on a third-party library so the team can decide consciously. Report it as an advisory 🔵 (or at most 🟡 when the leakage is broad, e.g. a vendor type spread across a public contract). **Never 🔴, never a merge-blocker** — frame it as a recommendation, not a required change. + +**What to surface:** + +- **Third-party type crossing the adapter boundary** 🔵/🟡: point out when a library's concrete class appears in a public API method signature/return type, a field of a cached or long-lived object, a REST/GraphQL response DTO, or an interface other modules consume. Recommend using the library **inside** a dedicated dotCMS wrapper/adapter/provider that maps its output into a dotCMS DTO (record/Immutable) or interface, with callers depending only on that. +- **New dependency ⇒ is there a seam?** 🔵: when the PR adds a dependency and calls it directly from business/REST code, note the new coupling and suggest whether an abstraction (interface + neutral DTO) should sit between them — especially for anything that might be swapped later (search store, storage backend, external API client, parser). + +How to apply without false positives: +- The wrapper/adapter class **itself** legitimately imports and uses the library — that's its job; don't flag library usage there. +- Ubiquitous foundational libraries used idiomatically across the codebase (vavr, Guava, Jackson annotations, standard JDK) are not what this targets — focus on domain/vendor libraries whose objects would couple dotCMS to a specific implementation. +- Don't demand a new abstraction for a one-off internal utility with no cross-boundary exposure — judge by whether the library type escapes into a contract others depend on. + +### New endpoints need an API test — Karate or Postman (dotCMS-specific) + +A new REST endpoint must ship with an API-level test so its contract is exercised in CI. dotCMS has two homes for these: +- **Karate**: `.feature` files under `test-karate/src/test/java/` (grouped by domain, e.g. `user/createToken.feature`). +- **Postman**: one collection per resource under `dotcms-postman/src/main/resources/postman/.postman_collection.json` (e.g. `FolderResource.postman_collection.json`, `Apps.postman_collection.json`). + +**Rule to enforce:** + +- **New endpoint ⇒ Karate or Postman coverage in the same PR** 🟡: if the PR adds a new JAX-RS handler, verify the PR also adds/updates a Karate `.feature` **or** the matching Postman collection covering it. Check the PR's full file list (`gh pr view --json files` or the diff) — if no `.feature` and no `*.postman_collection.json` change accompanies a new endpoint, flag the missing API test. Either one satisfies the rule; don't demand both. + +How to apply without false positives: +- Only for **new** endpoints (new path/method), not for internal refactors or non-contract changes to an existing endpoint already covered. +- If the PR clearly adds equivalent coverage another way that CI runs (e.g. an integration test that hits the endpoint via REST), note it rather than hard-failing — the intent is CI-exercised API coverage, and Karate/Postman is the standard home for it. + +### Prefer virtual threads for blocking/I-O-bound concurrency (dotCMS-specific) + +Core modules run on **Java 25**, so virtual threads (Project Loom) are available. For **I/O-bound or blocking** concurrent work — waiting on the network, disk (the distributed asset store), the DB, an index call, an external HTTP service — virtual threads are cheaper and scale far better than a bounded platform-thread pool: you can have millions of them, they cost almost nothing while blocked, and the code stays in the simple thread-per-task style. New concurrent code should prefer them where they fit. + +**Rules to enforce (on code the PR adds):** + +- **Prefer a virtual-thread executor over a new platform-thread pool** 🔵/🟡: when the PR introduces a new pool for blocking work — `Executors.newFixedThreadPool(...)`, `newCachedThreadPool()`, `newSingleThreadExecutor()`, or a hand-built `ThreadPoolExecutor` — and the tasks are I/O-bound, recommend `Executors.newVirtualThreadPerTaskExecutor()` instead. It removes the need to size/tune the pool and won't starve under many concurrent blocking tasks. +- **Prefer `Thread.ofVirtual()` over `new Thread(...)`** 🔵: a new one-off `new Thread(runnable).start()` for a blocking task should be `Thread.ofVirtual().name(...).start(runnable)` (or `.unstarted(...)`), which makes the intent explicit and avoids pinning an OS thread for the duration. +- **Watch for pinning that defeats the benefit** 🟡: inside a virtual thread, a `synchronized` block/method held **across a blocking call** pins the carrier thread and cancels the scalability win. When the PR adds virtual threads, flag blocking work guarded by `synchronized` and recommend a `ReentrantLock` (or restructuring so the lock isn't held across the blocking call) instead. + +How to apply without false positives: +- **CPU-bound work is the exception, not the target** — virtual threads give no throughput benefit for compute-heavy tasks; a sized platform-thread pool (often `availableProcessors()`) is the right tool there. Don't recommend virtual threads for CPU-bound loops. +- Don't demand rewriting **existing** platform-thread pools or `DotConcurrentFactory`/`DotSubmitter`-based code the PR merely touches — only raise this for **new** concurrency the PR introduces, and prefer the existing dotCMS concurrency abstraction if the surrounding code already routes through one. +- A pool deliberately bounded to throttle a downstream (rate-limiting an external API, capping DB connections) is intentional — note the option but don't hard-flag; the bound is the point. +- This is a modernization signal: 🔵 by default, 🟡 only when a new unbounded blocking workload on a fixed pool is a realistic starvation/latency risk. Never a merge-blocker on its own. + +### Records crossing the VTL/Velocity boundary need JavaBean getters (dotCMS-specific) + +dotCMS **forks Velocity 1.7 in-tree** (`dotCMS/src/main/java/org/apache/velocity/`), and its introspection predates records. Verified mechanics: + +- Property notation `$obj.foo` resolves through `UberspectImpl.getPropertyGet`, which tries **only**: `getFoo()` / `getfoo()` (`PropertyExecutor`), `Map.get("foo")` (`MapGetExecutor`), `get("foo")` (`GetExecutor`), then `isFoo()` (`BooleanPropertyExecutor`). **There is no lookup for a bare `foo()` accessor** — so a record's canonical accessor is invisible to property notation. +- The configured uberspect is `SecureUberspector` (`system.properties`: `runtime.introspector.uberspect`), which only swaps in `SecureIntrospectorImpl` for restricted classes/packages and **inherits that resolution chain unchanged**. Nothing in the fork is record-aware (no `isRecord` / `RecordComponent` usage anywhere). +- The failure is **silent**: `runtime.references.strict = false`, so an unresolved `$rec.foo` does not throw — it renders as the literal text `$rec.foo` in the page (and evaluates as null/false in `#if` / `#set`). Java compiles, Java-level tests pass, only the rendered output is wrong. +- Reflection itself is *not* the problem: `$rec.foo()` with explicit parens **does** resolve via `Introspector.getMethod` — **but only if the record class is `public`**. `ClassMap.createMethodCache` reflects a class only when `Modifier.isPublic(classToReflect.getModifiers())` and caches only public methods, so a package-private or non-public nested record has **no** visible methods at all; even `$rec.foo()` fails. + +**Rules to enforce:** + +- **A record reachable from a template must expose `getX()`** 🔴/🟡: when the PR adds or changes a type that can reach VTL — a `ViewTool` return value (`com.dotcms.rendering.velocity.viewtools`), anything put on the Velocity context (`context.put(...)`, `VelocityUtil`/`ContextUtil`, page-render or macro/directive output), or a value a `.vtl` in the PR dereferences — and that type is a `record`, require an explicit JavaBean getter for every component templates will read, **or** that the record be mapped/wrapped into a class (or `Map`) that has them. Records may declare extra methods, so `public String getFoo() { return foo; }` alongside the component is the cheap fix; implementing an interface that declares the getters also satisfies introspection (public interfaces are reflected too). +- **Replacing a getter-based type on a context object with a record is a breaking template change** 🔴: the compiler and Java-level tests stay green while every `$obj.prop` in shipped templates, starter sites and customer code silently degrades to literal text. Flag this hard and require getters or an adapter — plus a VTL-rendering test, not only Java assertions. +- **The record must be `public`** 🟡: flag a package-private record, or a non-public nested one, that is handed to the Velocity context — introspection skips non-public classes entirely, so *nothing* on it resolves, with the same silent-literal symptom. +- **Don't treat `$rec.foo()` as the contract** 🔵/🟡: the call syntax works for public records, but dotCMS templates, docs and customer code use property notation; the first VTL author who writes `$rec.foo` breaks silently. If the PR's own `.vtl` relies on parens to reach a record, note it and prefer getters. +- **Collections and nested records inherit the problem** 🟡: `#foreach($r in $list)` over a `List` hits it for every `$r.field`, and a record used as a component of another exposed type needs getters too — check the whole reachable graph, not just the top-level type. +- **Boolean components** 🔵: `BooleanPropertyExecutor` honors `isFoo()`, so a `boolean active()` component needs `isActive()` (or `getActive()`) to be readable as `$rec.active`. + +How to apply without false positives: +- **This does NOT contradict the "prefer immutable data carriers" rule below** — records remain the recommended carrier for Java-internal DTOs, and Jackson serializes them natively, so REST/GraphQL response records are fine. The rule is scoped strictly to the **Velocity/VTL boundary**. +- Establish reachability before flagging: look for viewtool/context/`.vtl` evidence in the diff. Don't assume every new record reaches a template. +- Values consumed through dynamic maps (`Contentlet`, `Map`-backed models) go through `MapGetExecutor` and need no getters. +- Don't demand getters for components templates never read; the requirement follows the fields actually exposed. + +### Quality / progressive enhancement (usually 🔵) +- Raw generics (`List` → `List`), missing `@Override`, missing `@Nullable`. +- **Prefer immutable data carriers over mutable get/set POJOs** 🔵/🟡: for a **new** value/DTO/config type introduced by the PR, flag a mutable POJO (private fields + getters + setters, no-arg constructor) and recommend an immutable alternative. Preference order in this codebase: (1) a Java **`record`** for a simple value carrier (see `com.dotcms.content.index.domain.ContentSearchResponse`/`SearchHit`/`Aggregation`); (2) the **Immutables** library — `@Value.Immutable` on an `Abstract*`/interface generating an `Immutable*` with a builder — when you need builders, defaults, derived/lazy values, or optional fields (222+ uses in the codebase). Immutability removes the shared-mutable-state bug class (cf. the cache-returned-Contentlet rule) and gives free `equals`/`hashCode`/`toString`. + - Guards: only for **new** carrier types — don't demand refactoring existing mutable models. **One exception to the record preference:** a carrier that reaches VTL needs JavaBean getters regardless (see the VTL/Velocity boundary rule above) — Velocity's introspection cannot see a record's `foo()` accessor. Setters are legitimately required for framework-bound beans (JPA entities, JSON/form deserialization targets that need mutability, JavaBeans an external lib populates) and for `Contentlet`-style dynamic-map objects — don't flag those. +- Legacy patterns where a modern equivalent is the standard (e.g. `Logger` over ad-hoc printing already covered above). +- **Always use braces to delimit scopes** 🔵: flag brace-less `if`/`else`/`for`/`while`/`do` bodies (single-statement or on the same line) introduced by the PR — every control-flow scope must use `{ }`. This prevents the classic goto-fail / dangling-statement bug and keeps diffs clean. (User preference — apply consistently on changed lines.) +- **Prefer CDI over manual instantiation** 🔵/🟡: for new services/beans, prefer CDI (`@Inject`, `@ApplicationScoped`/`@RequestScoped`, `@Default`) over `new`-ing collaborators or hand-rolled singletons. Flag a new hand-rolled singleton or a `new SomeService()` where a CDI-injectable collaborator is the fit. Note: `APILocator.getXxxAPI()` remains the established accessor for the legacy API layer — don't flag existing APILocator usage, but favor CDI injection for genuinely new components. +- Do NOT demand wholesale refactors of untouched legacy code — only comment on lines the PR actually changed. + +### OpenSearch / ES→OS migration awareness +If the PR touches indexing / search code, be alert to the migration invariants but stay within what the diff shows: +- ES-specific imports/types leaking outside the ES adapter layer. +- Index-name handling that adds a cluster prefix but drops the `.os` tag (or vice-versa) — a known bug class. +- Phase-dependent write behavior: OS write failures are fire-and-forget in phases 1/2 but must propagate in Phase 3. +Only raise these when the changed lines clearly implicate them; otherwise leave them out. + +## Self-check before output + +For every finding: (1) the file is in your assigned list, (2) the line exists in the diff, (3) you can quote the offending code, (4) confidence ≥ 75.
