- Extract the tenant-profile fetch lock stripe count to a named constant (PR #15744)
- Trim the stale global-lock sentence from the per-tenant lock comment (PR #15744)
- Rename the rate-limit onCreate callback to onMiss and document its idempotency requirement (PR #15744)
- Reuse a single tenant profile local in update(TenantProfileUpdateResult) (PR #15744)
- Make the transport callback thread pool size configurable via transport.callback_thread_pool_size (PR #15744)
- Add a parameterized test locking the TransportLimitsType enum-to-profile-field mapping (PR #15744)
- Add device/gateway rate-limit coverage asserting update(tenantId) reaches tracked entities (PR #15744)
- Add a same-tenant fetch-dedup test and pin the cross-tenant test to distinct stripes (PR #15744)
Construct CoapServer and the LwM2M bootstrap server inside the init try block so a failure in the constructor or build() is cleaned up by the existing catch. Guard CoAP shutdown() against a null server. Add a DTLS-enabled CoAP test that covers the dtlsSessionsExecutor shutdown branch.
The defective code lives in common/transport/transport-api and is shared by all
transports (MQTT, HTTP, CoAP, LwM2M, SNMP); the production incident happened to
surface on MQTT.
On a cold tenant-profile cache (e.g. after a cache clear + restart), a device
reconnect storm could serialize the whole transport instance behind tenant-profile
resolution, saturating the callback pool and stalling the node for ~15 minutes.
Two compounding causes are addressed:
- DefaultTransportTenantProfileCache held a single process-wide ReentrantLock across
the synchronous cross-service getEntityProfile round-trip, so every tenant-profile
cache miss in the whole process was serialized one-at-a-time. Replace it with a
bounded set of per-tenant locks (Guava Striped) so different tenants resolve
concurrently while concurrent misses for the same tenant are still de-duplicated.
- DefaultTransportRateLimitService performed that blocking fetch inside
ConcurrentHashMap.computeIfAbsent's mapping function, holding a CHM bin lock across
the remote round-trip. Pre-fetch the tenant profile before computeIfAbsent so no bin
lock is held across I/O.
Also de-duplicate the four near-identical getXRateLimits methods into one generic
helper, move the per-type rate-limit getters onto the TransportLimitsType enum, and
avoid fetching the tenant profile four times in update(TenantId).
Upgrade LangChain4j to 1.15.1-TB1 and migrate GitHub Models to the
official OpenAI integration (OpenAiOfficialChatModel), enabling JSON
Schema (strict) structured output for GitHub Models and exposing JSON
Schema as a response format for Anthropic and Amazon Bedrock.
- Rename model capability flags to supportsSchemalessJsonOutput() and
supportsJsonSchemaOutput(), declared explicitly per provider
- Push response-format capability checks into TbResponseFormat and
simplify response-format handling in TbAiNode
- Remove obsolete manual JSON escaping for GitHub Models, which now
double-escaped requests under the official OpenAI SDK
- Drop the now-obsolete opennlp-tools version pin (the upgraded
LangChain4j fork ships opennlp-tools >= 2.5.9)
- Update the AI rule node UI to offer response formats per provider,
refresh available model lists, and migrate toggle options to @if
- Expand configurer tests to verify per-provider model configuration
Extend the IoT Hub install dialog so installing a rule chain can also set
it as the Default rule chain on a Device or Asset profile in one step.
The confirm step shows three actions: Cancel, Install (creates the chain
without targeting any profile), and Set for profile (opens a picker step).
The picker step has Cancel, Back, and Install — confirming with a profile
that already has a non-null defaultRuleChainId routes through a
confirm-overwrite step before replacing it. CALCULATED_FIELD keeps its
existing single-button flow unchanged.
Backend:
* RuleChainInstalledItemDescriptor gains a nullable EntityId
targetProfileId field, persisted in the existing descriptor JSON column
(no schema migration; @JsonIgnoreProperties(ignoreUnknown=true) handles
pre-existing rows).
* DefaultIotHubService.installRuleChain() now accepts SecurityUser and
JsonNode data; a new setAsDefaultRuleChain() helper applies the chain
as Default rule chain on the selected DEVICE_PROFILE or ASSET_PROFILE
via the existing tbDeviceProfileService / tbAssetProfileService save
paths (so the change shows up in the tenant audit log as a normal
profile update).
Frontend:
* iot-hub-install-dialog.component grows a per-ItemType selectEntityConfig
map, a 'confirm-overwrite' state, and the methods
installAsEntityProfileDefault, selectEntityBack, resolveOverwrite,
confirmOverwriteReplace, confirmOverwriteCancel.
* tb-entity-select gets a 512px min-width above the gt-sm breakpoint so
the picker renders at a consistent width regardless of the prompt text
length (mirrors the pattern in recipient-notification-dialog).
* New i18n keys: rule-chain-install-desc, rule-chain-install-as-default,
select-profile-for-rule-chain, rule-chain-overwrite-title,
rule-chain-overwrite-body, rule-chain-overwrite-replace.
SimpleCalculatedFieldState.formatResult cast the double result down to
int via TbUtils.toInt when "Decimals by default" was 0 (the UI default).
BigDecimal.intValue() returns only the low-order 32 bits, so a sum
above ~2.1B wrapped to a negative number (e.g. 3,980,173,734 ->
-314,793,562).
Add TbUtils.toLong(double) alongside toInt (toInt is left untouched to
preserve TBEL script behavior), switch the CF precision=0 path to it,
and add a Long branch in createResultJson so the JSON node is emitted
as a numeric long
- Group tomcat, commons-lang3 version properties under spring-boot.version
- Drop thymeleaf override (PE-only dependency, not present in CE)
- Drop lz4 plumbing: kafka-clients 3.9.2 and cassandra-all 5.0.7 now transitively ship at.yawk.lz4:lz4-java, making the Dec 2025 CVE hack obsolete
AbstractTbQueueConsumerTemplate.poll() returned emptyList() immediately
when partitions was empty, bypassing both doPoll() and the secondary
sleep guard (which is also skipped for backends that report
isLongPollingSupported()==true, e.g. Kafka). The result was a
permanent CPU-burning loop on consumers whose partition assignment
ended up empty after a rebalance cascade — observed on 26
ie-downlink-consumer threads (~244% total CPU) until container restart.
Route the empty-partition path through sleepAndReturnEmpty() so the
caller honors durationInMillis regardless of long-polling support.
Moved NioEventLoopGroup allocations into the try block so that a
constructor failure for the second group no longer leaks the first.
Channel close failures during cleanup now attach via addSuppressed
instead of replacing the original BindException. Narrowed the outer
catch from Throwable to Exception, removing the brittle (Error) cast
that would have masked any direct Throwable subclass.
* feat(iot-hub): scaffold ALARM_RULE item type and CREATOR_VISIBLE_ITEM_TYPES
* feat(iot-hub): wire ALARM_RULE through browse, item card, detail dialog, installed items, and install dialog
* feat(iot-hub): reorder home cards, hide Dashboards, add Alarm Rules
* feat(iot-hub): scaffold ALARM_RULE descriptor and reject install with v4.3 upgrade hint
Registers AlarmRuleInstalledItemDescriptor in the Jackson polymorphism so
4.2 can browse Alarm Rule items from the marketplace without descriptor
deserialization failures.
The install handler explicitly rejects ALARM_RULE with a friendly message
asking the user to upgrade to v4.3+. The full install/update/delete
implementation depends on CalculatedFieldType.ALARM (added in v4.3) and
will land once master is merged into this branch.
* feat(iot-hub): hide redundant Type filter on Alarm Rules browse
* feat(iot-hub): show v4.3 update info dialog directly when installing an Alarm Rule
SolutionTemplateInstalledItemDescriptor and SolutionInstallResponse now
carry tenantTelemetryKeys and tenantAttributeKeys lists. SolutionService
.deleteSolution takes the full descriptor (instead of just the
created-entity list) so uninstall can also clean up tenant-scoped
telemetry/attributes. Update IotHub install descriptor population and
delete call sites; force-update path logs and continues if delete throws.
PathChildrenCache invoked EnsureContainers internally during start(), so
the parent znode existed when publishCurrentServer ran. CuratorCache does
not, so on a fresh ZK creatingParentsIfNeeded reaches ZKPaths.mkdirs with
the trailing-slash forPath argument and fails with
"Path must not end with / character", aborting Spring startup.
Switches the ZooKeeper-based service discovery from the deprecated
org.apache.curator.framework.recipes.cache.PathChildrenCache to the
modern CuratorCache replacement (Curator 5.x).
- ZkDiscoveryService: field type, construction, listener registration
and child-event handler migrated to the new API. parentPathFilter
and zkNodesDir guard preserve the original direct-children semantics
against the recursive-by-default behaviour of CuratorCache.
- ZkDiscoveryServiceTest: mock type and event construction adapted to
the new listener signature; existing assertions unchanged.
Eliminates 11 [WARNING] lines for PathChildrenCache deprecation on
lts-4.2 (targeted Tier 3 slice of #15481): repo-wide [WARNING] count
843 -> 832, [ERROR] count 0 -> 0.
Routes get/set/del/scan/getSet/hGet/hSet/hDel/lRange/zRem/getRange calls
through stringCommands()/keyCommands()/hashCommands()/listCommands()/
zSetCommands() instead of the deprecated shortcut methods on
DefaultedRedisConnection. Behavior-preserving — Spring Data Redis
delegates the deprecated overloads to these same typed commands.
Eliminates 70 deprecation warnings across RedisOtaPackageDataCache, five
Leshan-forked lwm2m stores (TbLwM2mRedisRegistrationStore,
TbLwM2mRedisSecurityStore, TbRedisLwM2MClientStore,
TbRedisLwM2MModelConfigStore, TbLwM2mRedisClientOtaInfoStore,
TbLwM2MDtlsSessionRedisStore) and the TbRedisLwM2MClientStoreTest unit
test, which now uses Answers.RETURNS_DEEP_STUBS to mock the typed
command chain.
Part of #15481 Tier 3 cleanup.
Added @Builder.Default to 5 fields with initializers in
MobileLayoutConfig (pages) and DefaultTenantProfileConfiguration
(maxCalculatedFieldsPerEntity, maxArgumentsPerCF, maxStateSizeInKBytes,
maxSingleValueArgumentSizeInKBytes). Dropped the redundant `= 0` on
Task.attempt (int default is already 0) to clear the same anomaly on
@SuperBuilder.
Eliminates 6 "@Builder/@SuperBuilder will ignore the initializing
expression" warnings from #15481 Tier 2. `[WARNING]` total drops
843 -> 837, `[ERROR]` unchanged at 0.
Creates missing system images from application/src/main/data/resources/images
during LTS patch startup, mirroring the upgrade-path loadSystemResources logic.
Existing system images in the DB are left untouched.
Prevents UnrecognizedPropertyException during rolling upgrades when a
newer node writes a cached entity with an added field and an older node
reads it back. The Redis-backed TbJsonRedisSerializer now uses
JacksonUtil.IGNORE_UNKNOWN_PROPERTIES_JSON_MAPPER instead of the strict
OBJECT_MAPPER used by JacksonUtil.fromBytes.
Store install state (form values, entity outputs, selected connectivity)
in DeviceInstalledItemDescriptor during registration. Installed Items
info icon for DEVICE type re-fetches the ZIP and opens the wizard in
read-only review mode:
- All stepper steps clickable (jump to any step)
- Form fields populated with stored values and disabled
- Entity progress shows all items as completed
- Markdown instructions rendered with resolved variables
- Download buttons and image galleries still work
- Single "Close" button in footer
Backend: add selectedConnectivity and installState fields to descriptor
Test: verify installState deserialization round-trip
The admin settings endpoint requires SYS_ADMIN authority but the device
install wizard runs as TENANT_ADMIN.
Fix: add getConnectivityInfo(baseUrl) to DeviceConnectivityService which
resolves host/port with baseUrl fallback (reusing existing getHost/getPort
logic). Expose via new TENANT_ADMIN endpoint GET /api/iot-hub/connectivity.
Remove AdminService dependency from the dialog component.
