When authenticated +Protection Encapsulation is configured, the outer 2.0 frame removes that +ambiguity and the predefined alias can be safely decoded after authentication. + +This mixed-version limitation must be documented for deployments requiring +unprotected sessionless predefined-alias PUBWOS: use a version-specific +endpoint strategy before declaring that particular profile supported. + ## Block 3 conformance test trace The test suite identifies the August 2026 CSD01 source commit pinned above.

This document distinguishes implementation changes from execu ## Cleanup and deployment gates -The legacy `MQTT_SNProtocolV2`, `PacketFactoryV2`, and their packet/state/listener hierarchy appear disconnected from the active `MqttSn2Protocol` instantiation path, but deletion requires checking all tests, compatibility extensions and protocol references. Keep those files until the correctness changes above have passed local validation. +The obsolete `MQTT_SNProtocolV2`, `PacketFactoryV2`, and the legacy v2 packet/state/listener hierarchy have been removed (32 files). The active `MqttSn2Protocol`, its CSD01 codecs, security providers and the MQTT-SN 1.2 implementation are retained. Compile and regression-test the removals before merging; absence of references in repository searches is not proof of runtime compatibility. Format all remaining active Java sources using the repository's Google Java conventions with a 180-character line limit, and use the standard Maps Messaging copyright/license header. Formatting must not alter packet handling or protocol semantics.

Make stream message counts reflect current storage rather than cumulative publication statistics.

Verify physical storage before acknowledging the assigned MAPS identifier. Reject unsupported multi-destination stream-global sequences explicitly. Add archive lifecycle and concurrent storage/seeding regression coverage. Validation: source/API, scope, licence and git diff checks only. Maven is unavailable and the environment provides Java 17; Java 21 compilation and JUnit tests remain unexecuted.

Register and seed each normal MAPS subscription independently; retain the separate publisher stream-global sequence limitation. Use mutable metadata maps in all four affected fixtures because Message adds server tags to the supplied map. Add a handler regression for multi-destination subscription registration and seeding. Validation: source/API and git diff checks only. Maven is unavailable; compilation and JUnit execution remain unperformed. Preserve the existing storage and browser characterisation tests.

Reuse valid synchronous state, and remove stale NATS registration metadata before creating replacement state through the ordinary subscription API. Apply the same validation to consumer subscriptions. Report the missing archive or consumer session explicitly and return an internal-error status for registration failures. Add regression cases for destination replacement and preservation of valid subscription state. Validation: source/API, scope, licence and diff checks. Maven is unavailable; compilation and JUnit tests remain unexecuted. Shared engine operations and the existing characterisation tests are unchanged.

Every original issue key is recorded in [the review CSV](sonar-review-2026-10-13.csv), with the rule, original line, source path, assessment and reason. + +- 205 findings addressed by straightforward source cleanup. +- 2 findings already addressed in the current branch. +- 702 findings deferred for targeted review or fresh-analysis verification. + +These are code-review assessments, not SonarCloud status transitions. A fresh analysis is required to confirm closures and the remaining count. No issues were suppressed or marked accepted. + +Cleanup includes literal constants; private/local names; equivalent method references, ternaries and patterns; numeric widening; redundant casts and record assignments while preserving null validation; explicitly documented no-op implementations; test-helper cleanup; safe Bash condition/glob syntax; and unchanged Docker package sorting. + +Items left for joint review include protocol/parser complexity, null/lifecycle risks, public and wire-facing APIs, exception/interruption policy, locks/volatile/resource ownership, serialization/equality, and deployment/download semantics. In particular, BaseRestApi.hasAccess() and RestAccessControl.hasAccess() require a functional authorization review; no permission behavior was changed here. + +## Verification + +Java 21 compilation of all 2,217 production and 1,206 test source files succeeded using the existing cached dependencies. Bash syntax checks and git diff whitespace checks passed. All 627 existing focused regression tests passed across 62 selected classes, covering packet boundaries, AMQP framing, MQTT aliases/keep-alive, NATS handler responses, configuration round trips, KPI/twin logic, AIS mapping, schema matching, persistent counters, HA lock handling and statistics. No assertions were weakened and no failing tests were disabled. + +Test-helper changes were limited to naming/import cleanup, private unused parameters, removal of the empty @BeforeAll hook, documentation of intentional no-op callbacks, and removal of an unused CTS argument array. No new tests were added for mechanical refactors. + +Maven online and offline test-compile attempts failed at dependency collection: repository.mapsmessaging.io is unavailable from this environment and some cached parent/BOM POMs have repository provenance that cannot resolve offline. No project dependencies, POM versions or build profiles were changed to bypass this. + +The initial focused JUnit run could not initialize Mockito's inline mock maker because this environment does not support self-attachment. Verification was rerun with Byte Buddy loaded at JVM startup, rather than changing tests or mock behavior. + +No Jira was created and no Jenkins build or SonarCloud analysis was triggered.

A transformer + that drops an event does not pass null into the analyser. +- Protect MQTT 3/5, MQTT-SN 1.2, MAVLink and satellite metadata access before a + session exists, while retaining active-session details. +- Reject missing MQTT-SN factory configuration with IOException. State, connection + setup and pipeline use the configuration already bound to the protocol. +- MQTT-SN removes stale queued entries without recursive draining. Network writes, + abandonment and retransmissions share an event-local once-only completion guard. + QoS>0 entries are not inserted twice while REGISTER is pending. Publish identifiers + are allocated only after a topic alias is available. +- Browser subscription construction reports an inactive parent with IOException. +- Modem command encoding reports missing payload/format with a descriptive state + error instead of an incidental null dereference. +- Two original null findings do not need guards: MQTT Publish constructors already + normalize null payloads to empty arrays, and Protocol's endpoint is final and + validated non-null by its constructors. Do not invent an empty authentication + configuration fallback for a malformed Protocol instance. + +## Concurrency review + +| Area | Ownership and monitor decision | +| --- | --- | +| Subscription contexts | All reads, snapshots, additions and removals use the same context-list monitor. Reproduced the former empty-check/get race. No callbacks occur under this monitor. | +| NATS pending writes | Registration and close coordinate on the tracker monitor. Frame callback replacement retains the same frame monitor used by complete(). Close snapshots first, releases the tracker, then completes frames. Callbacks execute outside both locks. | +| JetStream consumer creation/deletion and NATS subscription snapshots | Retain the connection's SessionState monitor, also used by its synchronized methods. A private lock in an individual handler would cease coordinating with other handlers. | +| TwinManager and TwinJsonPublisher | Retain the same EntityTwin monitor for updates and serialization. Do not replace these independently. | +| DroneTwin missionTransmission | Its MavlinkTransmissionState publishes immutable Snapshot records through a volatile reference. AtomicReference alone would add no protection to snapshot contents. | +| DroneTwin taskTransmission | A volatile mutable map still permits mutation by external holders. An immutable snapshot contract needs a separate API/serialization review; no live writer was found in this repository. | +| Connection state/endpoints/protocol and Disconnected activeEndPoint | Retain publication visibility and existing stateLock. A broader handoff review must test cancellation against late callbacks and transfer of endpoint ownership; replacing the fields mechanically does not establish safety. | +| CAN device | Retain deviceLock for binding/replacement/close and volatile publication to readers. The endpoint owns the device; individual readers must not close it. | +| MAVLink factory | Retain volatile publication when replacing dialect factories. Decoder/internal factory ownership requires library review before asserting general thread safety. | + +The MQTT-SN changes protect completion and claiming stale entries; they do not +claim to make every live-send/ACK/timeout operation in the pipeline atomic. + +## Lifetime ownership + +- AuthDbStoreManager owns its live MapDB database and maps until owner close. + Migration owns both temporary databases until copying is finished. Individual + maps are not closed merely because copyAllMaps returns. +- Fixed a distinct failure path: if live-store initialization/validation fails, + construction cannot transfer ownership to a manager, so the database is closed. + Successful construction leaves it open. Tests use real MapDB maps and invalid + mapping metadata, and also check the successful lifetime. +- Auth0TokenGenerator and the optional ChatGPT selector client create an HttpClient + per operation. Those clients are closed after their operation, including failure. + The ML regression stays under src/test/java-ml and does not alter default builds. + +## Time zones + +Seven calls now explicitly use ZoneId.systemDefault(): schema lookup, both legacy +schema timestamps, instance creation date, the system timestamp message, YAML +headers and configuration lint reports. Existing formats and local-zone behavior +are preserved; no UTC conversion or persisted timestamp migration is introduced. + +## Verification + +Regression tests reproduce null/lifecycle errors, the subscription read/remove +race, the NATS close/register race, duplicate MQTT-SN completion before and after +writing, publish-ID allocation before registration, invalid modem state, and +resource cleanup on failed operations/construction. + +- Java 21 compilation: 2,218 production sources (including the changed optional + ML client) and 1,212 test sources compiled successfully. +- Final focused selection: 82 classes, 863 tests found, 860 passed, three existing + skips, zero failures. Run with Australia/Sydney as the default time zone. +- Added 45 regression cases, including two under the optional ML test source tree. +- Independent source review: no remaining blockers after the MQTT-SN completion + and identifier ownership corrections. +- git diff --check passed. + +The normal Maven test command remains blocked during dependency collection by +unavailable cached repository metadata; POMs and dependency versions are unchanged. +No Jenkins run or Jira update is part of this cleanup.

Preserve identity when mappings are reordered and replace it when namespace mappings change. BREAKING CHANGE: MQTT bridge session IDs now include namespace configuration. On first deployment, existing bridge sessions and queued messages are not resumed; old sessions remain subject to their existing expiry policy.

It allocates unique +identifiers from 1 through a configured maximum (at most 65535), incrementing +and wrapping while skipping outstanding identifiers. Capacity exhaustion fails +immediately; allocating an existing delivery still succeeds at capacity. + +The key is an exact topic string plus a signed long message identifier. Where +multiple independent subscription deliveries share a topic/message pair, pass +a stable subscription key instead of the topic. The owning protocol controls +that identity; the storage has no dependency on subscription objects. + +## API + +- `memory(maximum)` or `open(path, maximum, durability)`. +- `allocate(topic, messageId)` returns `Allocation(packetId, existing)`. +- `getPacketId(topic, messageId)` returns the identifier, or null. +- `getDelivery(packetId)` returns `Delivery(topic, messageId)`, or null. +- `clear(packetId)` / `clear(topic, messageId)` remove completion/expiry/eviction state. +- `outstanding()` returns an immutable recovery snapshot. +- `flush()` provides a durability barrier; `compact()` reclaims completed history. +- `close()` releases ownership and flushes; it does not delete persistent records. + +`existing=true` means this delivery was allocated earlier. Protocols may use it +as a retransmission marker once allocation is placed at the correct send +boundary. It does not prove the network received the original packet. DUP +remains zero for QoS 0; QoS 2 handshake recovery requires additional protocol +state and is not implemented by this mapping component. + +## Cost and durability + +Lookups use in-memory hash indexes and perform no file reads. Existing +allocation and unknown clear perform no writes. A new persistent allocation +appends 29 bytes plus UTF-8 topic/key length; completion appends 17 bytes. +Channels remain open for the owning session's storage lifetime. Packet-ID +search is bounded by configured capacity; normal allocation is one lookup, +but near-full wraparound can scan the identifier range. + +SYNC forces each mutation before returning. BATCHED appends without forcing; +the owner must call `flush()` before network actions requiring crash durability. +Batching reduces durability barriers, not the number of append writes. There +is no background scheduler or hidden periodic force policy. + +The journal has a versioned header, protected record lengths and CRC32C. +Recovery discards an incomplete final append, and rejects complete corrupt or +inconsistent records. Compaction writes and forces a new journal, atomically +replaces the old one, then forces its directory. Ownership remains held by a +separate lock throughout replacement. Journal paths must not be symbolic +links; use one canonical path and do not create hard-link aliases, especially +across compaction generations. Atomic replacement and directory forcing must +be supported by the deployment filesystem. + +History and startup work grow until the owner schedules compaction. No +per-ACK map rewrite or full identifier-space preallocation is performed. + +## Integration boundary + +This component is not yet connected to MQTT or MQTT-SN. Session expiry/clean +start must close and remove the owned journal; reconnect must retain it. +Allocation/completion ordering with engine interest persistence, packet-ID +reservation for control traffic, connection-generation ACK guards and QoS 2 +stage persistence remain protocol integration work. Missing files are created +by `open`; the session owner must detect loss of an expected existing journal +rather than silently treating it as a new session. + +Verification includes real abrupt JVM exit after durable allocation, partial +append recovery, corruption rejection, allocation/clear/reuse, ownership, +compaction failure and concurrent callers. This does not establish physical +power-cut guarantees or benchmark sustained throughput. diff --git a/src/main/java/io/mapsmessaging/storage/delivery/PacketIdJournal.java b/src/main/java/io/mapsmessaging/storage/delivery/PacketIdJournal.java new file mode 100644 index 0000000000..4aa3d50a82 --- /dev/null +++ b/src/main/java/io/mapsmessaging/storage/delivery/PacketIdJournal.java @@ -0,0 +1,225 @@ +/* + * Copyright [ 2024 - 2026 ] MapsMessaging B.V. + * Licensed under the Apache License, Version 2.0 with the Commons Clause. + */ +package io.mapsmessaging.storage.delivery;

Validate acknowledgement stages, reserve control IDs safely, protect retired callbacks and exercise reconnect, persistence, expiry, capacity and concurrency.

Do not introduce features requiring a newer language level. + +## Principles and scope + +New code should look and behave as though it belongs in the existing MapsMessaging codebase. Prioritise correctness, clarity, maintainability, and predictable runtime behaviour over brevity or individual preferences. + +Apply these standards to new code and code being substantively modified. Follow surrounding conventions where they do not contradict this document. Do not reformat the entire repository or unrelated sections of a file. Keep cosmetic-only changes in separate commits from behavioural changes. + +## Explicit types + +Do **not** use Java local-variable type inference (`var`) in production code or tests, including enhanced loops and local declarations. State the type explicitly and prefer interfaces when appropriate. + +```java +DeliveryStateCoordinator coordinator = deliveryStateCoordinator; +List packetIds = new ArrayList<>(); +Map messages = new HashMap<>(); +``` + +## Formatting and control flow + +- Use two-space indentation and spaces rather than tabs. +- Use a **soft target of 180 columns**. Do not wrap merely because a line exceeds that target by one or a few characters. Break lines where it improves comprehension, not to meet a mechanical threshold. +- Put opening braces on the same line as the statement or declaration. +- Use braces for all `if`, `else`, `for`, `while`, `do`, and other control-flow bodies, even one-statement bodies. +- Expand `try`, `catch`, `finally`, and conditional blocks across multiple lines. Do not compress multiple independent statements onto one line. +- Use consistent spacing around operators, after commas, and between logical sections. Avoid drive-by formatting of unrelated code. + +```java +if (message == null) { + return; +} + +try { + processMessage(message); +} catch (IOException exception) { + logger.error("Unable to process message", exception); + throw exception; +} +``` + +## Imports and naming + +Use normal imports and simple type names. Avoid fully qualified Java class names inside method bodies unless needed to disambiguate types. Prefer explicit imports to wildcard imports in new code. + +Give classes, fields, methods, parameters, and local variables descriptive names. Avoid unclear one-letter names and unnecessary abbreviations. Conventional, tightly scoped identifiers are acceptable where unambiguous. Preserve established public API names and recognised protocol terminology. + +## Methods, features, and class organisation + +Create focused helper methods when they clarify a meaningful operation, express a domain concept, reduce duplication, or make resource ownership or control flow easier to understand. Do not introduce trivial wrappers solely to shorten methods. Keep related lifecycle operations grouped. + +Modern Java features such as records, switch expressions, pattern matching, and text blocks are permitted where they improve readability and remain compatible with the configured Java version. Prefer loops over streams when ordering, mutation, exceptions, or debugging are clearer with a loop. Do not use `var`. + +Use Lombok consistently with surrounding code; do not add it indiscriminately. + +## Defensive programming + +**Agreed policy:** Validate aggressively at external and untrusted boundaries, but rely on explicit, enforced contracts inside the application. + +- Validate network/protocol input, configuration, persisted state, and other externally controlled values. +- Establish internal invariants through constructors, API contracts, and appropriate state transitions. +- Do not scatter redundant null checks and arbitrary defaults through internal code to hide broken invariants. +- Use explicit failures for violated internal contracts rather than silently continuing with invalid state. Choose a meaningful exception type and preserve context. +- Use fallback behaviour only when it is part of a defined protocol, compatibility, or recovery contract. +- Differentiate malformed external input (which should normally be handled and isolated) from programmer errors (which should remain visible). +- Do not add defensive branches merely to satisfy static analysis if they weaken the stated contract. + +## Concurrency and lifecycle + +Document important ownership, synchronization, reference publication, callback, shutdown, recovery, and replacement assumptions where they are not obvious. + +Use `volatile` for visibility and safe publication when appropriate; it does not make compound operations atomic or mutable referents thread-safe. Use synchronization, atomic types, and concurrent collections only when they provide the actual required guarantees. Read a changeable reference once into a local variable if a null check and later operation must act on the same object. + +Prefer invoking externally supplied callbacks outside internal locks when safe. Capture the necessary state under lock, preserve lifecycle semantics, and test ordering, closure, recovery, and replacement paths. + +## Exceptions and resources + +Preserve original exceptions and their causes. Never silently swallow meaningful operational errors or mask the primary exception during cleanup. Use explicit error handling at a level where the failure can be handled meaningfully. + +Prefer try-with-resources for locally owned resources. When ownership transfers to a longer-lived component, document the hand-off and close the resource on failed initialization. Never close a resource after a successful ownership transfer merely to satisfy a static-analysis warning. + +## Tests + +Prefer constructor-valid instances, existing test builders, and reusable fixtures for stateful components. Mock external collaborators as needed, but avoid partial mocks that bypass essential initialization (including `CALLS_REAL_METHODS`) unless specifically justified and fully initialized. + +Tests should verify observable behaviour and preserve meaningful assertions. Regression tests should reproduce the defect and verify the fix; do not disable or weaken failing tests to make a build green. + +Use established test data locations such as `target` or `target/data`. For concurrent behaviour, test lifecycle, ordering, and completion rather than depending solely on fixed sleeps. + +## Comments and documentation + +Explain purpose, non-obvious decisions, invariants, ownership, compatibility requirements, and concurrency contracts. Do not narrate self-explanatory statements. Write Javadoc for public APIs and complex contracts where useful. Preserve the existing source licensing and copyright conventions. + +## Static analysis + +Treat SonarCloud and other static-analysis results as findings to investigate, not automatic proof of defects. Fix actual issues. For justified false positives, use a narrowly scoped suppression or accepted finding with a concise technical explanation. Do not distort working architecture merely to achieve a passing grade. + +## Changes, commits, and validation + +- Keep formatting-only refactors separate from behaviour changes. Preserve interfaces, execution order, exceptions, concurrency, and lifecycle semantics when formatting. +- Keep commits focused and use the repository's established commit-message and Jira-reference conventions. +- Inspect diffs for accidental unrelated changes. +- Verify compilation and run focused tests for relevant changes; run broader regression suites when warranted. +- Report tests and builds as passing only when results have been observed. +- Do not create branches, Jira issues, run Jenkins, or merge without the required approval. + +## Adoption + +These standards govern future and substantively modified Java code. Clean up existing code gradually when touching the relevant area; do not initiate a repository-wide reformat. If an existing public interface or compatibility requirement conflicts with a style preference, preserve behaviour and document the exception.
