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. diff --git a/Jenkinsfile b/Jenkinsfile index 40842fcc2b..931cc22a62 100644 --- a/Jenkinsfile +++ b/Jenkinsfile @@ -139,10 +139,16 @@ def runBlock = { String stageName -> echo "${stageName}: running ${selectedTests.size()} test classes" def selector = selectedTests.join(",") - sh """#!/bin/bash - set -euo pipefail - mvn clean test -Dtest='${selector}' ${mavenCommon} - """ + // Start each block with fresh authentication and data state. + // Keep MAPS_DATA inside this workspace even if the agent defines it globally. + def testDataDirectory = "${pwd()}/target/data" + withEnv(["MAPS_DATA=${testDataDirectory}"]) { + sh """#!/bin/bash + set -euo pipefail + rm -rf -- target/data + mvn clean test -DMAPS_DATA='${testDataDirectory}' -Dtest='${selector}' ${mavenCommon} + """ + } } stage("${stageName} - JUnit") { diff --git a/docs/protocols/mqtt-sn-2-csd01-review-status.md b/docs/protocols/mqtt-sn-2-csd01-review-status.md new file mode 100644 index 0000000000..11e6f28865 --- /dev/null +++ b/docs/protocols/mqtt-sn-2-csd01-review-status.md @@ -0,0 +1,34 @@ +# MQTT-SN 2.0 CSD01 architecture and interoperability status + +Reference: MQTT-SN 2.0 CSD01 (August 2026), OASIS source revision `0dae5066d123d068ddca2ddb861ce8858aafee92`. + +Tracking: MSG-324.

This supersedes the outdated local socket restriction and no-Jenkins status recorded earlier. +- Jenkins SonarCloud analysis was uploaded under the `development` branch identity.

Active `MqttSn2Protocol` is **60.5% overall coverage**; `MqttSn2Lifecycle` and `MqttSn2OutgoingDeliveryManager` are approximately 88.8% and 88.9%. Many obsolete 2.0 implementation classes have 0% coverage and must not be confused with the active protocol path. These metrics precede the latest protection and topic-alias changes. + +## Sessionless PUBWOS on a mixed-version UDP listener + +CSD01 §3.6 permits PUBWOS without a Virtual Connection. The server now handles +an unprotected PUBWOS by explicit Topic Name as QoS 0, without treating it as +MQTT-SN 1.2 traffic. **Unprotected predefined-alias PUBWOS is deliberately +rejected on the dual-version UDP port**, because its type `0x12` collides +with MQTT-SN 1.2 SUBSCRIBE and some frames are ambiguous.

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. diff --git a/docs/quality/sonar-review-2026-10-13.csv

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 stage 1 survives restart and compaction, allowing +the owning protocol to replay PUBREL while awaiting PUBCOMP. + +## 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 and +a stage advance or original QoS selection appends 18 bytes. Repeated stage updates do not append. +Control reservations are memory-only and never appear in journal records or +recovery snapshots; connection owners must release them on ACK or disconnect. +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. +Version 1 journals without stage/QoS records remain readable, with defaults. +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 must be supported by the deployment filesystem. +Directory forcing is used where supported by the platform. Windows Java NIO +cannot open directory channels, so Windows forces journal file contents but +cannot promise the same power-loss durability for directory entries/renames. + +On `flush()`, journals of at least 1 MiB automatically compact when their +mutation record count reaches four times a conservative live-record estimate +(`3 * outstanding deliveries + 1`). The gate uses in-memory counts and a file +size check; it never scans outstanding entries below the threshold. Recovery +restores the count, and compaction resets it to the retained record count. +Explicit `compact()` remains available. No per-ACK map rewrite or full +identifier-space preallocation is performed. + +## MQTT and MQTT-SN ownership + +MQTT 3.1.1/5 and MQTT-SN 1.2/2 share one store per session for outbound +QoS 1/2 deliveries. Memory sessions use an in-memory store; persistent sessions +retain a journal across disconnects and reload it after restart. Clean Start, +session expiry and permanent removal close and delete the owned journal. +Stable delivery keys distinguish subscription filters, shared groups and actual +physical destinations, including wildcard subscriptions with equal message IDs. + +Reliable PUBLISH allocation persists its packet ID and original wire QoS before +transmission. Re-delivery reuses that ID and sets DUP. QoS 2 PUBREC advances the +journal before sending PUBREL. Normal exchanges and recovery complete exact +broker acknowledgement tasks before sending PUBREL. The durable PUBREL stage survives message expiry +until PUBCOMP, and cannot become a fresh PUBLISH after a QoS downgrade. +Terminal acknowledgements retire mappings; expiry/capacity cleanup retires only +PUBLISH-stage records. Control traffic reserves IDs in the same session space +without persisting connection-scoped reservations. Runtime retirement callbacks +run outside journal locks and preserve subsequent allocations. + +The alias store remains a topic-to-alias registry.
