Change Log

Unreleased

Update the org.realityforge.arez artifacts to version 0.214.
Inline the removal of orphaned subscriptions as part of the response processing pipeline.

v6.137 (2024-11-15) · Full Changelog

Changes in this release:

Sort the entities by id within each class in replicant.Subscription

v6.136 (2024-08-16) · Full Changelog

Changes in this release:

Update the org.realityforge.javax.annotation artifact to version 1.1.1.
When an entity is removed from replicant then forcibly unsubscribe from any subscriptions where that entity is the root instance. Historically this would be cleaned up in removeOrphanedSubscriptions but may take a brief time to do so. This change avoids potential crashes when downstream code directly observes replicant Subscription objects and attempts to access instance root.

v6.135 (2024-08-09) · Full Changelog

Changes in this release:

Add hook method AbstractReplicantEndpoint.onSessionOpen(...)

v6.134 (2024-07-19) · Full Changelog

v6.130 (2022-10-20) · Full Changelog

Changes in this release:

Explicitly catch SecurityException when processing WebSocket messages to avoid emitting stack traces in the logs.

v6.129 (2022-10-18) · Full Changelog

Changes in this release:

Introduce the concept of the FATAL_ERROR state for connectors where no attempts to reconnect accor. This state is set when we get an error message that starts with the string "java.lang.SecurityException:" under the assumption that a user will not recover until given appropriate permissions.

v6.128 (2022-10-17) · Full Changelog

Changes in this release:

Stop passing the filter from the source graph to a target graph during a traversal of an internal subscription graph link if the target graph expects no filter parameter. Otherwise, when a non-bulk subscription occurs, the filter is added to target and will not match the same graph when multiple graph links points at the same target graph and the client will crash with an error like: "Attempt to update channel 1.45.X but channel does not allow dynamic updates of filter and channel has not been explicitly subscribed.".

v6.127 (2022-10-03) · Full Changelog

Changes in this release:

Remove CacheType.EXTERNAL as no longer in use.
Cascade cache invalidations to dependent cached type graphs to avoid failure scenario when a chain of cached graphs as an invalidation in internal node of chain.

v6.126 (2022-09-27) · Full Changelog

Changes in this release:

Reduce debug logging level around subscribing to "required channels".
Avoid attempting to subscribe to required type channel if already subscribed.

v6.125 (2022-09-20) · Full Changelog

Changes in this release:

Pause arez when changing the replicant connection, otherwise if the server initiates a close and the client has pending requests then the code will react during subscription purge and generate an error while the connection is null but the state has yet to be updated.
Ensure non-cached required type graphs are transmitted to the client.

v6.124 (2022-09-19) · Full Changelog

Changes in this release:

Update the org.realityforge.react4j artifacts to version 0.191.

v6.123 (2022-05-02) · Full Changelog

Changes in this release:

Update the org.realityforge.zemeckis artifact to version 0.14.
Update the org.realityforge.react4j artifacts to version 0.191.
Update the org.realityforge.arez artifacts to version 0.205.
Update the org.realityforge.grim artifacts to version 0.09.
Upgrade to require JDK 17 as a baseline.

v6.122 (2022-04-15) · Full Changelog

Changes in this release:

Modify AbstractSessionContextImpl.generateTempIdTable(...) so that it chunks the insertions into the temp id table to work around limitations in some versions of SQL server of a maximum of 1000 rows in an INSERT statement.

v6.121 (2022-04-07) · Full Changelog

Changes in this release:

Use tryLock() rather than lock in implementation of removeClosedSessions(), pingSessions(), removeAllSessions() in ReplicantSessionManagerImpl to avoid deadlocks. These actions will just be skipped if they would otherwise cause blocking.
Avoid attempting bulk subscribe attempts submitted to the server for an existing subscription a matching filter.
Generate a AttemptedToUpdateStaticFilterException exception when attempting to update a channel with a static filter.
Rework the way we expand changes for processing so that we break it down into cycles and for each cycle we:
- collect pending channel links
- select the highest priority channel with pending links
- select the channel links for the selected channel and perform a bulk subscribe for all channel links with the same channel id
Add isExplicitSubscribe parameter to bulkCollectDataForSubscribe(...) and bulkCollectDataForSubscriptionUpdate(...) on ReplicantSessionManagerImpl to enable controlling the behaviour in generated domgen code.

v6.120 (2022-04-01) · Full Changelog

Changes in this release:

Expose the "productionMode" compilation time parameter using Replicant.isProductionMode().
Add SystemSchema.getInwardChannelLinks(int), SystemSchema.getOutwardChannelLinks(int), EntitySchema.getOutwardChannelLinks() and ChannelSchema.getOutwardChannelLinks() helper methods. These are not used at runtime but are primarily intended for usage in supporting tooling and testing infrastructure

v6.119 (2022-04-01) · Full Changelog

Changes in this release:

Change the ChannelLinkSchema.auto property to being a boolean rather than an int.

v6.118 (2022-03-31) · Full Changelog

Changes in this release:

Introduce ChannelLinkSchema entities that are not used at runtime but are a placeholder to store additional data about a channel/graph.
Add EntityMessage.safeGetLinks() helper method that initializes a links field if not present.
Rename linkSourceGraphToTargetGraph(...) to bulkLinkFromSourceGraphToTargetGraph(...) in AbstractSessionContextImpl to match conventions present in domgen generated code.
Add initial support for "bulk" loading of type graphs. While "bulk" loading is a bit of a misnomer given that type graphs have at most 1 subscription, the term is synonymous with loading using SQL queries in domgen generated code.
Remove return value from bulk loading methods as implementations never return false, they generate an exception or perform the bulk load.
Fix a bug in AbstractSessionContextImpl.bulkLinkFromSourceGraphToTargetGraph(...) where the ids used in linking from the source graph to the target graph were incorrectly inverted.

v6.117 (2022-03-29) · Full Changelog

Changes in this release:

Pass the ChangeSet when performing bulk subscribe except on the outermost call where locks are acquired as the bulk subscribe methods may be invoked when expanding links outside the initial transaction.

v6.116 (2022-03-28) · Full Changelog

Changes in this release:

Ensure that graphs that support bulk loads always go through the bulk loads path even when the client subscribes or updates the filter of a single instance of the graph.

v6.115 (2022-03-25) · Full Changelog

Changes in this release:

Update the org.realityforge.react4j artifacts to version 0.187.
Update the org.realityforge.arez artifacts to version 0.203.
Update the org.realityforge.guiceyloops artifact to version 0.110.
Update the org.realityforge.grim artifacts to version 0.06.

Changes in this release:

Update the org.realityforge.react4j artifacts to version 0.185.
Update the org.realityforge.arez artifacts to version 0.200.
Update the org.realityforge.zemeckis artifact to version 0.13.
Update the org.realityforge.akasha artifacts to version 0.28.

v6.113 (2021-09-24) · Full Changelog

Changes in this release:

Rename Entity.delinkFromInternalFilteringSubscription(Subscription) method to Entity.delinkFromFilteringSubscription(Subscription) and modify the implementation to support calling with any filtered graph. The intent is to support mutable routing parameters.

v6.112 (2021-09-21) · Full Changelog

Changes in this release:

Add an OnEntityUpdateAction hook to the SystemSchema that will be invoked for every update received from the server. The intent is to support INTERNAL filtering using mutable routing parameters.
Add a Entity.delinkFromInternalFilteringSubscription(Subscription) method to help support mutable routing parameter management.

v6.111 (2021-09-21) · Full Changelog

Changes in this release:

Ensure that changes that should invalidate a cache will invalidate the cache even when there are no sessions connected.

v6.110 (2021-09-16) · Full Changelog

Changes in this release:

Update the org.realityforge.akasha artifacts to version 0.24.

v6.109 (2021-08-25) · Full Changelog

Changes in this release:

Update the org.realityforge.akasha artifacts to version 0.21.
Update the org.realityforge.arez artifacts to version 0.199.
Add support for the concept of a UserObject associated with a ReplicantSession that can be used to associate arbitrary application-specific information with a session.

v6.108 (2021-07-27) · Full Changelog

Changes in this release:

Update the org.realityforge.react4j artifacts to version 0.183.
Upgrade the org.realityforge.akasha artifacts to version 0.15.
Upgrade the org.realityforge.braincheck artifacts to version 1.31.0.

Upgrade the org.realityforge.akasha artifact to version 0.05.
Upgrade the org.realityforge.arez artifacts to version 0.193.
Upgrade the org.realityforge.react4j artifacts to version 0.181.
Upgrade the org.realityforge.zemeckis artifact to version 0.09.
Upgrade the org.realityforge.grim artifacts to version 0.05.
Upgrade the au.com.stocksoftware.idea.codestyle artifact to version 1.17.
Migrate from using Elemental2 to Akasha when interacting with the Browser API.

v6.105 (2021-02-01) · Full Changelog

Avoid crashes in AbstractReplicantEndpoint.sendErrorAndClose(...) and AbstractReplicantEndpoint.getReplicantSession(...) that can occur when the application is being un-deployed.
Reduce log message from WARNING to FINE in AbstractReplicantEndpoint.onClose(...) when unable to locate replicant session associated with websocket session as this scenario can occur during normal operation of the service when the replicant session had previously aborted/errored (likely due to authentication errors).

v6.104 (2021-01-11) · Full Changelog

Change the way ReplicantSessionManagerImpl determines whether a message was initiated by a session so that it takes into account sessions that have been closed.
Upgrade the org.realityforge.zemeckis artifact to version 0.08.
Name the Zemeckis tasks.

v6.103 (2021-01-07) · Full Changelog

Upgrade the org.realityforge.react4j artifacts to version 0.179.
Upgrade the org.realityforge.org.jetbrains.annotations artifact to version 1.7.0.
Upgrade the org.realityforge.arez.testng artifact to version 0.24.
Upgrade the org.realityforge.arez artifacts to version 0.192.

v6.102 (2021-01-06) · Full Changelog

Adopt the org.realityforge.zemeckis:zemeckis-core artifact to provide scheduling primitives.

v6.101 (2020-12-15) · Full Changelog

Avoid error when attempting to close and already closed websocket in AbstractReplicantEndpoint.

v6.100 (2020-12-15) · Full Changelog

Avoid log spam when WebSocket connections are closed after the application has undeployed.

v6.99 (2020-11-30) · Full Changelog

Workaround concurrency bug in Payara/Tyrus/Catalina by catching NullPointerException in WebSocketUtil and ignoring the exception. This change just removes the logging of these exceptions to production logs and lets Payara/Tyrus/Catalina fail silently and recover normally.
Avoid processing the same session multiple times within ReplicantMessageBrokerImpl across multiple calls to processPendingSessions(). This stops a single blocked session from locking the entire thread pool responsible for invoking processPendingSessions().

v6.98 (2020-11-25) · Full Changelog

Add ReplicantSessionManager.deleteAllCacheEntries() so that bulk change operations that are done without using JPA entities can trigger a cache reset.
Ensure that a deletion of an entity will result in any caches that contain the entity as being reset. Previously only entity changes caused cache resets.
Abort the subscribe/unsubscribe/bulkSubscribe/bulkUnsubscribe actions if the associated session is closed.
Support arbitrary degrees of concurrency in ReplicantMessageBroker.processPendingSessions() so that if a session is taking a long time in expandLinks(), other sessions can make progress.

v6.97 (2020-11-16) · Full Changelog

Upgrade the org.realityforge.org.jetbrains.annotations artifact to version 1.6.0.
Upgrade the javax artifact to version 8.0.
Add final modifier to the SecuredReplicantRpcRequestBuilder class.
Generate an exception if the SecuredReplicantRpcRequestBuilder attempts to build a request but no keycloak token is available.

v6.96 (2020-08-10) · Full Changelog

Ensure that the rest endpoints in AbstractSessionRestService acquire the session lock prior to accessing session data.

v6.95 (2020-08-03) · Full Changelog

Upgrade the org.realityforge.arez.testng artifact to version 0.20.
Upgrade the org.realityforge.arez artifacts to version 0.188.
Upgrade the org.realityforge.react4j artifacts to version 0.173.

v6.94 (2020-06-08) · Full Changelog

Upgrade the org.realityforge.react4j artifacts to version 0.162.
Upgrade the org.realityforge.arez.testng artifact to version 0.14.
Upgrade the org.realityforge.arez artifacts to version 0.182.
Upgrade the org.realityforge.braincheck artifact to version 1.29.0.

v6.93 (2020-06-05) · Full Changelog

Avoid reporting the parameters for the action Connector.completeAreaOfInterestRequests(...) to the spy subsystem.
Pause in the debugger when superdevmode is enabled and an error is generated in the ApplicationEventBroker when invoking onApplicationEvent(...) method for any ApplicationEventHandler listener.

v6.92 (2020-06-02) · Full Changelog

Upgrade the org.realityforge.react4j artifacts to version 0.160.

v6.91 (2020-05-29) · Full Changelog

Upgrade the org.realityforge.react4j artifacts to version 0.157.
Upgrade the org.realityforge.arez.testng artifact to version 0.11.
Upgrade the org.realityforge.arez artifacts to version 0.179.

v6.88 (2020-05-15) · Full Changelog

Upgrade the org.realityforge.react4j artifacts to version 0.156.
Upgrade the org.realityforge.arez artifacts to version 0.177.
Upgrade the org.realityforge.arez.testng artifacts to version 0.09.

v6.87 (2020-04-29) · Full Changelog

Upgrade the org.realityforge.arez artifacts to version 0.175.
Upgrade the org.realityforge.arez.testng artifacts to version 0.07.
Upgrade the org.realityforge.react4j artifacts to version 0.154.
Rework the way EntityBrokerLock so that multiple locks can be acquired by different connectors simultaneously. Only when all locks are released will the broker re-enable or resume.

v6.86 (2020-04-27) · Full Changelog

Make the AreaOfInterest.getRefCount() method public. This makes it easier to integrate into systems that used earlier versions of replicant.

v6.85 (2020-04-23) · Full Changelog

Correct the return type of ReplicantContext.getInstanceSubscriptionIds() to return a set of integer ids rather than a set of object ids.
Remove SubscriptionUtil.instanceSubscriptionToValues() method as it is not used and no longer useful in the current architecture.
Correct the typing of SubscriptionUtil.convergeCrossDataSourceSubscriptions(...) method as ids must be integers in replicant v6.

v6.84 (2020-04-16) · Full Changelog

Upgrade the org.realityforge.arez artifacts to version 0.173.
Change setFilter(...), registerInwardSubscriptions(...) and registerOutwardSubscriptions(...) on SubscriptionEntry back to public as the methods can be invoked if an application is implementing a bulk subscriptions.
Change ReplicantSessionManagerImpl.subscribe(...) to be public access so that propagation of filters on subscription updates can be implemented in downstream projects.
Introduce ReplicantSessionManagerImpl.propagateSubscriptionFilterUpdate(...) template method that can be overidden to implement filter propagation.

v6.83 (2020-04-02) · Full Changelog

Change the routing infrastructure so an entity message can be associated with multiple instance graphs of the same type. i.e. An entity can belong to the Event/1 and Event/2 channel.

v6.82 (2020-03-31) · Full Changelog

Fix "concurrent modification of collection" bug when removing manually linked graph links.

v6.81 (2020-03-26) · Full Changelog

Generate an error in production builds when there is an unexpected error processing a network message.

v6.80 (2020-03-26) · Full Changelog

Reduce access levels on several methods on SubscriptionEntry as they are not expected to be called outside of the framework.
Change the API of ReplicantSessionManagerImpl.collectDataForSubscriptionUpdate to accept a session so that the collection process can also inspect session to determine what code managed graph links need to be updated.
Expose ReplicantSession.isSubscriptionEntryPresent(...)
Refactor the way ReplicantSessionManagerImpl.updateSubscription(...) works to support updates that signal that code-managed graph-link links should be unsubscribed when the soure entity is filtered out of graph.

v6.79 (2020-03-25) · Full Changelog

Upgrade the org.realityforge.arez artifacts to version 0.172.
Fix a bug exhibited when filtered subscriptions update the filters and the filter methods use traverses across entities to determine whether an entity should be omitted from the updated subscription. If the entities traversed occurred lexicographically earlier than the entity and could be filtered out then they may already be disposed when later entities are attempting to determine whether they should remain in the graph which can cause crashes or unexpected behaviour. This has been fixed by deferring the unlinking till after the set of filtered out entities is determined.

v6.78 (2020-03-20) · Full Changelog

Rework the initialization sequence in ReplicantContext to eliminate the need for the deferScheduler=true parameter to be applied to the @ArezComponent annotation in replicant.Converger and replicant.ReplicantRuntime. This produces a more reliable mechanism for deferring observer reactions.
Remove the need to cache the ArezContext in ReplicantContext by moving the requestSync logic to replicant.ReplicantRuntime.
Refactor the initialization sequences when Zone's are enabled so that zone creation is always contained within an Arez scheduler lock to avoid access of data from observers before the data has been prepared.

v6.77 (2020-03-20) · Full Changelog

Upgrade the org.realityforge.arez artifacts to version 0.171.
Simplify some of the test infrastructure by adopting the org.realityforge.arez.testng:arez-testng dependency.
Fix an error that occurs as the server was not locking the session when it updated the eTags.
Fix bug that would trigger an invariant failure in clients when a cached response was returned. The cause was a duplicate ok message for the initiating request.

v6.76 (2020-03-05) · Full Changelog

Fix concurrency bug that results from routing a message to a client before the client is aware that they are subscribed to a channel. This can occur if the message is in a packet queued prior to the subscription update packet.

v6.75 (2020-03-04) · Full Changelog

Upgrade the org.realityforge.braincheck artifact to version 1.26.0.
Fix bug where a request that caused changes replicated to the user could result in a hang in the client due to failing to send back a answer over replicant.

v6.74 (2020-03-02) · Full Changelog

Upgrade the org.realityforge.arez artifacts to version 0.170.
Add ReplicantSession.maybeSendPacket(...) helper method that will only send a packet for ChangeSet if it is non-empty or it is marked as required.
Refactor ReplicantSessionManagerImpl.saveEntityMessages(...) so that each session is processed in succession rather than processing all sessions simultaneously an phase-by-phase, event-by-event. This is preparing for a future mechanism via which sessions can be locked during processing to avoid concurrency issues as outlined in stocksoftware/rose#716 and #4.
Remove unused ChangeAccumulator.
Expose ChangeSet.merge(Collection<Change>) and ChangeSet.mergeActions(Collection<Change>) as public methods.
Remove invariant guard that is no longer needed post v6.71 when invoking Replicant.context().request(...).
Expose ReplicantSession.isOpen() helper method.
Add ChangeSet.hasContent() helper method that is used to determine whether a ChangeSet is required to be sent to the client.
Add FINE and FINER level logging to ReplicantSession when events of interest occur. The intent is to make it easy to turn logging on trace problems during development and production.
Remove the AbstractSecuredSessionRestService.getAuthService() method as it is unused.
Refactor the way processing is performed on the server. The entity change messages are still collected within the transaction but they are now packaged up and posted to separate queues for each session. Another task in a separate thread will then process the change messages for each session. The selection/routing of each message to a session occurs in this separate thread as does the expansion of GraphLink messages. This fixes several dead-lock scenarios that could occur as described in #16
Add locking to ReplicantSession so that routing messages and altering of subscriptions requires the lock acquisition. This avoids several crashes related to concurrency issues such as those described in #4 and several issues within rose.

v6.73 (2020-02-20) · Full Changelog

Add WebSocketConfig.create(...) helper method and make the constructor private access to simplify creating the config object.

v6.72 (2020-02-20) · Full Changelog

Refactor ReplicantRpcRequestBuilder to accept the base url during construction.
Add SecuredReplicantRpcRequestBuilder to simplify generation of secure request builders.

v6.71 (2020-02-20) · Full Changelog

Upgrade the org.realityforge.arez artifacts to version 0.169.
Upgrade the org.realityforge.react4j artifacts to version 0.151.
Upgrade the org.realityforge.org.jetbrains.annotations artifact to version 1.5.0.
Refactor the way requests are generated so that if a request occurs before a replicant connection has been established then the request is added to a pending queue which is processed the next time connection is established.

v6.70 (2020-02-11) · Full Changelog

Generate a runtime exception when EntityChangeBroker is instantiated but has been compiled with the compiler flag -XdisableClassMetadata as the broker will fail in suprising ways due to lack og Class.getSuperClass() support.

v6.69 (2020-02-10) · Full Changelog

Add template methods into AbstractReplicantEndpoint so that the application can get notification when a command is processed by the websocket handler and/or a websocket is closed.
Introduce AbstractEeReplicantEndpoint to simplify writing endpoints in an enterprise java environment.
Replace template method AbstractReplicantEndpoint.getLogger() with a static field to reduce the amount of code generated by downstream consumers.
Generate an invariant failure if ReplicantContext.newRequest is invoked before replicant has established a connection with the underlying server.
Add ReplicantContext.findConnectionId(...) method to expose the underlying connection/session id to client code.

v6.68 (2020-02-07) · Full Changelog

Fix bug introduced in v6.67 that resulted in potentially incorrect filters being used for instance graphs.

v6.67 (2020-02-06) · Full Changelog

Optimize access to channels from SystemMetaData and remove unused SystemMetaData.getChannels() method.
Replace ChannelMetaData._typeGraph boolean flag with ChannelMetaData._instanceRootEntityTypeId to make it easier to drive business logic and to write tests for subscription logic.
Extract generic ReplicantSessionManagerImpl.processDeleteMessages() from downstream libraries to make it easier to refactor logic in subscription managers.
Expose instance channels by index in SystemMetaData. The ultimate goal is to create a fast mechanism for accessing metadata in the subscription manager.
Implement previously abstract ReplicantSessionManagerImpl.shouldFollowLink() and generate an exception if called without being overriden.
Remove NoSuchChannelException as never caught, handled distinctly and nor does it provide more useful data.

v6.66 (2020-02-05) · Full Changelog

Import ReplicantSession.pingTransport() from downstream consumers that is used to keep alive the web socket connection when passing through some intermediaries that close websockets when idle.
Add ReplicantSessionManagerImpl.pingSessions() method that pings all sessions to keep them alive. This is expected to be called periodically to ensure websockets are not closed by intermediaries such as firewalls and load balancers.

v6.65 (2020-01-31) · Full Changelog

Refactor the replicant.TransportContext interface to make it public and to ensure all methods are callable from outside the package.
Extract replicant.AbstractTransport class to facilitate the construction of alternative transport implementations.

v6.64 (2020-01-30) · Full Changelog

Change SubscriptionService.findInstanceSubscription(...) so that it is effectively readOutsideTransaction=ENABLED to allow it to be invoked by imperative code outside an Arez action. Typically this is done via code such as Replicant.context().findInstanceSubscription(...) and is often used to detect whether a subscription is present locally.

v6.63 (2020-01-29) · Full Changelog

Make ReplicantRuntime.getState() a @Memoize(readOutsideTransaction=ENABLED) method so that it can be read in imperative code without the need to explicitly wrap it in an Arez action. Typically this is done via code such as Replicant.context().getState().
Catch exceptions in server code when calling expandLinks(...) and rather than aborting the entire request, just close the session that generated the error and continue processing the change set for other sessions.

v6.62 (2020-01-24) · Full Changelog

Add logging to AbstractReplicantEndpoint when web socket actions occur. This mandates that downstream libraries implement a template method to retrieve the Logger to log to.

v6.61 (2020-01-22) · Full Changelog

Upgrade the org.realityforge.grim artifacts to version 0.04.
Upgrade the org.realityforge.guiceyloops artifact to version 0.106.
Upgrade the org.realityforge.react4j artifacts to version 0.148.
Remove the schemaName field from all the events defined in the package replicant.events. The schemaName value is only present when the replicant.enable_names compile time constant is set to true which is rarely the case in production environments. The field was not used in any downstream projects.

v6.60 (2020-01-10) · Full Changelog

Decouple from arez.component.CollectionsUtil which will be removed from Arez in the near future.

v6.59 (2020-01-10) · Full Changelog

Upgrade the org.realityforge.arez artifacts to version 0.165.
Avoid crash scenario where a delayed dispose in response to decRef reducing the reference count to 0 triggers after AreaOfInterest was explicitly disposed. In most applications this should not be a problem but applications that include reference counting as well as explicit dispose can trigger this bug.
Rework AreaOfInterestService to avoid depending on the arez internal class arez.component.internal.AbstractContainer as the API and behaviour of this type can change between Arez releases, potentially breaking replicant.
When ReplicantContext.activate() is invoked, attempt to send synchronization messages for any connectors where relevant. This catches an error scenario where a sync attempt should be made when the context is deactivated but is instead discarded.
Make sure a sync is requested if an AreaOfInterest is removed and there is a local Subscription present for the AreaOfInterest.

v6.58 (2020-01-08) · Full Changelog

Re-introduce an event based notification mechanism for legacy applications when significant state changing events occur. The events emitted are introduced on an as-needed basis and currently include; SubscribeCompletedEvent, SubscribeStartedEvent, SubscriptionUpdateCompletedEvent, SubscriptionUpdateStartedEvent, MessageProcessedEvent. This code is omitted unless the replicant.enable_events compile time setting is set to true. The code will likely be removed in the future as the legacy applications are decommissioned.

v6.57 (2020-01-06) · Full Changelog

Upgrade the org.realityforge.react4j artifacts to version 0.147.
Upgrade the org.realityforge.arez artifacts to version 0.164.
Expose the EntityChangeBroker.isPaused() method for use by downstream libraries.

v6.56 (2019-12-19) · Full Changelog

Remove error parameter from several spy events as it is no longer available within a WebSocket system.
Avoid attempting attempts to set connection in Connector if the same value ias passed as the setter has the side-effect of generating spy messages which can be confusing.
Rename constants in ConnectorEntry to be named *_REGEN_PER_SECOND rather than *_REGEN_PER_MILLISECOND to reflect actual behaviour.
When Connector reconnection attempts are rate limited, schedule another attempt in the future.

v6.40 (2019-04-17) · Full Changelog

Upgrade the org.realityforge.braincheck artifact to version 1.16.0.
Upgrade the org.realityforge.arez artifacts to version 0.136.
Update the org.realityforge.react4j dependencies to version 0.125.
Explicitly invoke Converger.removeOrphanSubscriptions() method when the session is synchronized rather than relying on @Observer being triggered on changes. This is more explicitly behaviour and simpler to understand. This fixes a problem introduced in the v6.37 which would result in no channels being unsubscribed as they observer would no longer activate.

v6.39 (2019-04-16) · Full Changelog

Change security of AbstractSecuredSessionRestService so sessions are not allowed to access their individual details as no longer required.
Remove userID from session as no longer populated or used.

Upgrade the org.realityforge.com.google.elemental2 artifacts to version 1.0.0-b21-6a027d2.
Upgrade the org.realityforge.braincheck artifact to version 1.15.0.
Omit attributes not relevant to WebSocket based sessions from the the rest API describing sessions.
Upgrade the org.realityforge.arez artifacts to version 0.135.
Refactor the replicant.Transport interface to remove methods 4-arg requestSubscribe(), requestSubscriptionUpdate() and requestBulkSubscriptionUpdate() that can be reimplemented as calls to 6-arg requestSubscribe().
Refactor the serverside code to mandate the use of WebSocket transport layer. As a result of this there is no need to maintain infrastructure for representing packets, queuing and retrying packets. Thus the Packet class and PacketQueue have been removed. The endpoints designed for manipulation of sessions (i.e. creating, destroying, subscribe, unsubscribe etc) has also been removed.
ReplicantSessionManager.invalidateSession(...) now accepts a ReplicantSession session as a parameter rather than String sessionId as all callers have a session available.
ReplicantSessionManager.subscribe(...) no longer returns CacheStatus parameter as it is no longer used.
Remove the dependency on the org.realityforge.gwt.webpoller:gwt-webpoller:jar artifact.
Move the InvalidHttpResponseException exception to the package org.realityforge.replicant.client.gwt as that is the only remaining place where it is used.
Remove Transport.onMessageProcessed() as flow control is no longer part of the application layer and is instead managed by the WebSocket implementation.
Removed sequences from the server-to-client message as messages can never be transmitted out of sequence.
Refactor Connector.state to be readable outside a transaction.
Remove the need to pass onDisconnectionError handler to the Transport.disconnect(...) method and instead treat any error while disconnecting as a disconnect error.
Remove the need to pass onConnectionError handler to the Transport.connect(...) method and instead treat any error while connecting as a connect error.
Remove the need to pass onDisconnection handler to the Transport.disconnect(...) method and directly invoke callback from Transport.
Decouple the ChangeSetParser class from the javaee infrastructure and remove code used for testing (i.e. EntityChangeDataImpl) from the main source tree into the test source tree.
Rename the Transport.disconnect() method to Transport.requestDisconnect() to align with intent and existing patterns in the Transport interface.
Add "type" field to the ChangeSet message sent from the server to client in preparation for allowing multiple different types of messages to be emitted from the server. Refactor the client side representation to have AbstractMessage and ServerToClientMessage parent classes to allow some code sharing.
Add SubscribeMessage and UnsubscribeMessage classes to represent the requests that are sent to the server.
Rename ChangeSet to ChangeSetMessage to match the naming conventions of other messages.
Significant rework of the entire network layer to enable WebsocketTransport.

v6.37 (2019-03-18) · Full Changelog

Upgrade the org.realityforge.com.google.elemental2 artifacts to version 1.0.0-b20-bfe6e22.
Stop tracking last access time of the ReplicantSession as it is no longer used. The sessions expire after the associated web socket is closed rather than after a specified idle period.
Stop tracking createdAt time of the ReplicantSession as it has never been used.
Replace ReplicantSessionManagerImpl.removeIdleSessions() with ReplicantSessionManagerImpl.removeClosedSessions() as not expecting to need to maintain infrastructure for polling clients.
Change the return type of ReplicantSessionManagerImpl.sendPacket(..) to void rather than returning a Packet as the return value was only ever used in tests.
Change the return type of PacketQueue.addPacket(..) to void rather than returning a Packet as the return value was only ever used in tests.
Rename PacketQueue.getPacket(int) to PacketQueue.findPacketBySequence(int) to align with existing conventions.
Add ReplicantSession.sendMessage(...) helper method that delegates to internal queue.
Add the org.realityforge.spritz:spritz-core:jar dependency in preparation for client-side websockets.
Allow the creation of a ReplicantSession to be based of a WebSocket session.
Add a method ReplicantSessionManagerImpl.removeAllSessions() that can forcibly close all connected clients.
Add a ReplicantSession.ack(...) that delegates to the underlying queue and may send next packet on WebSocket connection.
Remove the explicitSubscribe parameter from the ReplicationSessionManager.subscribe(...), ReplicationSessionManager.bulkSubscribe(...), ReplicationSessionManager.unsubscribe(...) and ReplicationSessionManager.bulkUnsubscribe(...) methods as the value of the parameter is only ever expected to be true.
Remove the changeSet parameter from the ReplicationSessionManager.subscribe(...), ReplicationSessionManager.bulkSubscribe(...), ReplicationSessionManager.unsubscribe(...) and ReplicationSessionManager.bulkUnsubscribe(...) methods as the value is always the result of the call EntityMessageCacheUtil.getSessionChanges().
Ensure that ReplicantSessionManagerImpl explicitly expires sessions when the component is destroyed.
Align the ChannelAddress.toString() output with the format used to serialize channel across the wire.
Add a ChannelAddress.parse(String) method to parse the channel from the wire format.
Remove the ReplicationSessionManager.updateSubscription(...) and ReplicationSessionManager.bulkUpdateSubscription(...) methods that have not been used since the move to "modern" replicant.
Remove several methods from ReplicationSessionManager not used outside of tests. These are remnants of replicant's evolution and include:
- getSessionKey()
- delinkSubscription(...)
- bulkDelinkSubscription(...)
Remove or reduce the access level of several methods in ReplicationSessionManagerImpl that are only used by tests.
Remove the local cache key during subscribe if the cache key is stale.

v6.36 (2019-03-05) · Full Changelog

Remove AbstractSessionContextImpl as it was effectively unused. While subclasses exist, none of the subclasses invoked any of the AbstractSessionContextImpl methods.
Add ChannelAddress.hasSubChannelId() helper method.
Add support for a separate DELETED channel action message that indicates that the root of an instance graph has been deleted and will not be coming back. This allows the client-side to respond appropriately and differs from REMOVED that may just indicates that has been removed from the area of interest.
Emit the SubscribeRequestQueuedEvent before triggering scheduler so that the spy message is emitted prior to performing action which improves traceability.
Avoid converging any actions for DELETED AreaOfInterest instances.

v6.35 (2019-03-01) · Full Changelog

Add ChannelMetaData.hasFilterParameter() helper method to simplify the code that works differently depending on the presence or non-presence of thefilter parameter.
Add filtering type of INTERNAL that indicates that a graph is filtered but there is no parameter that controls the filtering behaviour and instead the filtering is due to internal structure of the data or the server.

v6.34 (2019-02-27) · Full Changelog

Caching fixed as the synthesis of the cache key had diverged between the code that added data to the cache and the code that retrieved data from the cache. To avoid a similar problem in the future the generation of the cache key has been moved to the ChannelAddress class.

v6.33 (2019-02-27) · Full Changelog

Upgrade the org.realityforge.com.google.elemental2 artifacts to version 1.0.0-b19-fb227e3.
Change the serialized representation of links from an entity to a channel from an array of json objects of the form [{"cid": 20, "scid": 1},{"cid": 20, "scid": 2},{"cid": 1}] to a more succinct representation as an array of strings of the form ["20.1","20.2","1"]. This involved several internal changes as well as removal of the replicant.messages.EntityChannel data transport class.
Change the serialized representation of entity references from {"typeId":42,"id":23,...} to a more compact {"id":"42.23",,...}.
Omit the etag property and the requestId property if they are null rather than transmitting nulls.
Upgrade the org.realityforge.braincheck artifact to version 1.13.0.
Support ChannelAddress.getName() even when Replicant.areNamesEnabled() returns false as that behaviour is required and was implemented in other places.
Change the serialized representation of channels from "channel_types":[{"cid": 20, "scid": 1, "action":"add"}] to a more compact "channels":["+20.1"]. Filtered channels actions were optimized in a similar fashion.

v6.32 (2019-02-24) · Full Changelog

Upgrade the org.realityforge.com.google.jsinterop artifact to version 1.0.0-b2-e6d791f.
Upgrade the org.realityforge.com.google.elemental2 artifacts to version 1.0.0-b18-f3472e7.
Update the org.realityforge.react4j dependencies to version 0.121.

v6.31 (2019-02-18) · Full Changelog

Upgrade the org.realityforge.com.google.elemental2 artifacts to version 1.0.0-b17-6897368.
Add explicit reference counting to AreaOfInterest to ensure that object is disposed only if there is no explicitly interested parties. Also added in a small delay for AreaOfInterest so that a dangling AreaOfInterest can persist for a short period of time without unloading such as when changing pages.
Update ReplicantSubscription to use explicit reference counting so that AreaOfInterests are correctly released when no longer used.
If the server removes a subscription from the client then remove the associated AreaOfInterest if any. This typically occurs when the root entity in an instance graph is removed and the instance graph is subsequently removed.

v6.30 (2019-02-14) · Full Changelog

Update the org.realityforge.arez dependencies to version 0.130.
Update the org.realityforge.react4j dependencies to version 0.119.
Remove the unused @*Ref annotated methods getContext(), getComponentName() and component() from SubscriptionService and ReplicantRuntime.

v6.29 (2019-02-12) · Full Changelog

Fix pom for replicant-client so that it includes react4j dependency.
Update project to reflect migration to replicant4j/replicant project.
Emit the name of the graph in the session rest service to aid debugging.
Fix bug in ReplicantSubscription that resulted in @Action triggering during dispose.

v6.28 (2019-02-07) · Full Changelog

Update the org.realityforge.arez dependencies to version 0.128.
Update the org.realityforge.react4j dependencies to version 0.117.
Avoid invariant failure when updating the status of a AreaOfInterest for a subscription that is implicitly subscribed and is in the process of being explicitly subscribed but is currently in NOT_ASKED or LOADING state.
Avoid dropping subscription requests in the Connector when the request is upgrading an implicit subscription to an explicit subscription.
Fix Converger so that AreaOfInterest instances that match an existing subscription will only have their status updated if the existing subscription is explicit, otherwise the normal "request subscription" process will be initiated.

v6.27 (2019-02-04) · Full Changelog

Remove the prop onNotAsked from the ReplicantSubscription component as it represents a state that is never presented to the user and is followed in quick succession by the OnLoading state and can thus be replaced by the onLoading prop.

v6.26 (2019-02-04) · Full Changelog

Work around bug resulting from react4j upgrade that merged the componentWillUnmount and dispose steps for react4j components. Previously we were able to invoke @Action annotated methods in componentWillUnmount() to release resources but this is no longer possible. Arez should allow the use of @CascadeDispose in this context but due to current limitations in Arez this is not possible. A workaround until this limitation has been addressed, has been added to the ReplicantSubscription class.
Upgrade Elemental2 artifacts to groupId org.realityforge.com.google.elemental2 and version 1.0.0-b14-2f97dbe. This makes it possible to use a newer version of the Elemental2 library in downstream products.

v6.25 (2019-01-30) · Full Changelog

v6.23 (2019-01-18) · Full Changelog

Fix the release process to push release to staging repository and Maven Central.

v6.22 (2019-01-18) · Full Changelog

Rename some react lifecycle methods in ReplicantSubscription so that they align with the names of the annotations rather than the names of the methods that needed to be overridden in the past.

v6.21 (2019-01-17) · Full Changelog

Remove deployment from TravisCI infrastructure as it is no longer feasible.
Update the org.realityforge.arez dependencies to version 0.122.

v6.18 (2018-11-02) · Full Changelog

Enhance the console message for the spy event AreaOfInterestStatusUpdatedEvent to include the status that the AreaOfInterest was changed to.
Fix the subscribe and unsubscribe to ensure they responded appropriately to the X-Replicant-RequestComplete header. Previously an AreaOfInterest request (i.e. a subscribe or unsubscribe) could occur multiple times if the response to the AOI request has not been received by the time the RPC call has returned. Historically this happened infrequently (if at all) but due to timing changes in other parts of the application this became a frequent occurrence. The fix was to treat subscribe/unsubscribe like any other request to ensure that they are sequenced appropriately.
Update the org.realityforge.arez dependencies to version 0.111.
Update the org.realityforge.react4j dependencies to version 0.103.

v6.17 (2018-10-16) · Full Changelog

Update the org.realityforge.react4j dependencies to version 0.100.

v6.13 (2018-10-04) · Full Changelog

Change ReplicantSubscription.getId() to return a primitive integer rather than a boxed Integer.

v6.12 (2018-09-27) · Full Changelog

Upgrade the org.realityforge.gwt.webpoller:gwt-webpoller:jar artifact to version 0.9.8.

v6.11 (2018-09-25) · Full Changelog

Remove super.componentDidMount() and super.componentDidUpdate( prevProps, prevState ) calls from the ReplicantSubscription react component as not needed as parent methods are empty as of react4j version 0.96
Fix bug where converger will not re-converge if multiple AreaOfInterest are added simultaneously and the the later AreaOfInterest instances can not be grouped into the first AreaOfInterest instance. The converger would previously incorrectly halt after the first action completed.

v6.10 (2018-09-21) · Full Changelog

Update the org.realityforge.arez dependencies to version 0.107.
Update the org.realityforge.react4j dependencies to version 0.96.
Update the org.realityforge.braincheck dependencies to version 1.12.0.

v6.09 (2018-08-24) · Full Changelog

During code-optimization the Converger.converge() method stopped observing filters when converging filters which mean that if the filter changed it would no longer re-converge the state of the world. This bug has been fixed by an explicit observe of the filter field on AreaOfInterest.

v6.08 (2018-08-23) · Full Changelog

Update the org.realityforge.arez dependencies to version 0.105.
Update the org.realityforge.react4j dependencies to version 0.93.
Remove the interface org.realityforge.replicant.client.EntityRegistry and related infrastructure. The code is currently unused and unlikely to be adopted in the near future.
Remove the interface org.realityforge.replicant.client.EntityLocator and related infrastructure. This has been replaced by arez.Locator interface.
Replace the interface replicant.Linkable with the arez.component.Linkable interface.
Replace the interface replicant.Verifiable with the arez.component.Verifiable interface.

v6.07 (2018-07-30) · Full Changelog

Change the scope of the dependencies enlisted in the @Autorun actions on the Converger to eliminate monitoring of entities in preConverge() and to re-add dependencies on AreaOfInterest collection.

v6.06 (2018-07-27) · Full Changelog

Update the org.realityforge.arez dependencies to version 0.102.
Explicitly limit the scope of the dependencies enlisted in the @Autorun actions on the Converger so that only the data required to trigger changes are monitored.

v6.05 (2018-07-26) · Full Changelog

Change the scheduler used by the browser from using setTimeout to using requestAnimationFrame. This resulted in a shorter and more consistent delay between successive invocations.
Fix bug in Connector.onMessageProcessed() that resulted in an invariant failure when spies were disabled but invariant checking was enabled.
Avoid an invariant failure by passing null for request name when performing "Sync" action if Replicant.areNamesEnabled() returns false.
Fix concurrency bug where an invariant failure was triggered if a request was removed by the polling code prior to the rpc request returning.
Update the org.realityforge.arez dependencies to version 0.100.
Fix bug where the Subscription and AreaOfInterest enhanced arez subclasses failed to supply a valid id in production compiles. This resulted in the objects being incorrectly stored within containers and thus applications failing at runtime.
Update the org.realityforge.react4j dependencies to version 0.87.

v6.04 (2018-07-24) · Full Changelog

In the ConsoleSpyEventProcessor class, correct the log message when a SubscriptionUpdateCompleted event is generated.
Fix a concurrency bug where the WebPoller could be left paused on receipt of a "ping" message.
Add tasks to cleanup artifacts from staging repositories as part of the release process.

v6.03 (2018-07-17) · Full Changelog

Fix a bug in Connector related to interleaving of subscription removal and removal of the instance root that would result in invariant failure in normal scenario.
Fix a bug in Connector related to processing the removal of an entity after the subscription that contained the entity has been removed.
Upgrade the org.realityforge.gwt.webpoller:gwt-webpoller:jar artifact to version 0.9.7.
If the connectionId changes between when the WebPollerTransport starts and completes a subscribe or unsubscribe request then skip handling the response as it is no longer relevant.
If the underlying connection has been disconnected or is in error then do not attempt to perform a poll action. Instead skip the request assuming that it will come good or that the poller will be stopped.
Avoid initiating subscribe or unsubscribe requests if the connection has been disconnected. This can occur if a subscribe or unsubscribe action completes with an error.
Avoid passing messages back to Connector via the TransportContext if it has been disconnected. This can happen after an error occurs.
Update the org.realityforge.arez dependencies to version 0.98.
Update the org.realityforge.react4j dependencies to version 0.84.
Implement Transport.unbind() so that Connector instances that disconnect or result in an error can disassociated with prior transport and successfully re-connect without the failure of the prior transport either disconnecting new connection or blocking the establishment of the new connection.
Handle scenario where the Connector.progressMessages() method is called back by the timer but the underlying connection has already been disconnected. Infrequent occurrence in practice but this avoids inconsistent state when and error messages in the console when it does occur.
Remove some unused session parameter from ReplicantSessionManager.collectDataForSubscribe(...) and ReplicantSessionManager.collectDataForSubscriptionUpdate(...) as not used and should never be used as methods accept parameters to describe the data required.
Introduce SyncRequest, InSyncEvent, OutOfSyncEvent and SyncFailureEvent spy events to notify listeners when synchronization events occur.
Add the ability to "ping" the backend from the client replicant application to check whether the backend has any requests in progress to thus perform a poor-mans network synchronization. This is still somewhat error prone if another party sends a message that is added to the servers message queue for pinging session and that message relies on existing implicit subscription already present that would be removed as an orphan subscription.
Fix bug in the AbstractSessionRestService so that the synchronized flag is correct.
Fix bug in Converger.convergeAreaOfInterest(...) so that if an AreaOfInterest is added when an existing Subscription already exists, the AreaOfInterest is marked as LOADED rather than getting stuck in the NOT_ASKED state.
Enhance the replicant.Transport.Context interface to allow access to underlying request ids received and transmitted. Also support the recording of "sync" request ids so that synchronization attempts can be verified.
Rename replicant.Connection._lastRequestId to _lastTxRequestId so that it is clear that the request id is the last id transmitted.
Change the way request callbacks are invoked so that they are invoked after the request has been removed from the connection. This allows the callback to inspect the connection to get the current connection state.
Move to a J2CL compatible version of the jetbrains annotations libraries.
Update the org.realityforge.guiceyloops:guiceyloops:jar dependency to version 0.95.
Make sure that RequestEntry instances are removed from the connection after they have been handled.
Change the time at which orphan subscriptions are removed. Rather than on receipt of each message, the removal will only occur when a synchronization has happened on all data sources. This limits the window during which the server skips a subscription as the client is implicitly subscribed but the client is in the process of removing the subscription that it believes is an orphan.

v6.02 (2018-07-03) · Full Changelog

Fix Connector.completeAreaOfInterestRequest() to handle scenario where the area of interest request completes after a connection disconnects. This can happen as a result of errors during area of interest request or during normal overlapping requests.

v6.01 (2018-07-02) · Full Changelog

Link EntitySchema instances associated with channel to ChannelSchema to simplify validation of graph when or if needed.

v6.00 (2018-07-02) · Full Changelog

Stop using replicant specific mechanisms for managing state and move to Arez for state management. This is a major rewrite of the library and involved large scale changes. See the git history for full details.

Updated the AbstractDataLoaderService to support bulk loads. Aggregated consecutive AOI actions that can be grouped into a single bulk load. Submitted by James Walker.
Updated the ContextConvergerImpl to schedule multiple AOI actions where they are compatible with bulk loading. Submitted by James Walker.

v0.5.94 · Full Changelog

in AbstractSecuredSessionRestService, check the PreferredUsename claim against the UserID associated with the Replicant Session, rather than the TokenID. Works with the change on 0.5.93. Submitted by James Walker.

v0.5.93

in ReplicantSecuredSessionManagerImpl, use the PreferredUsename claim as the UserID associated with the Replicant Session, rather than the TokenID. The TokenID will change each time the token refreshes. An alternative is the Subject token but everywhere this is deployed also adds the claim PreferredUsename which is easier to read. Submitted by James Walker.

v0.5.92

Use GWT super-source feature to replace FilterUtil.

v0.5.91

Made all variants of ReplicationRequestUtil.runRequest public.

v0.5.90
