Server

Upgrade from LTS 2019 to LTS 2021

Updated: October 14, 2021

For the general upgrade process, see the page Upgrading the Nuxeo Platform.

This chapter highlights some major information about upgrade from Nuxeo Platform LTS 2019 (10.10) to Nuxeo Platform LTS 2021 (2021.x). We strongly encourage you to also have a quick read of the upgrade notes.

Prerequisites

This upgrade notes assume that Nuxeo Server is up to date in 10.10 before the upgrade, which means:

  • Nuxeo Server is on 10.10 with the latest hotfixes
  • All the migrations have been successfully completed (comments and trash).

Installation and Configuration

Configure Thumbnail Computation Maximum Duration Since 2021.5

The maximum duration to produce a thumbnail is now limited by default to 5min. This limit is applied to the listener in charge of creating a new thumbnail and also to the recomputeThumbnail bulk action.

The limit can be tuned with:

nuxeo.thumbnail.transaction.timeout.seconds=300

Note that the limit is set at the transaction level (and not at the command level) because thumbnail generation may involve multiple commands.

Enable Log4j Filter to Conceal Sensitive Data Since 2021.2

In order to enable the policy to mask sensitive data, you must configure a Log4j2 RewriteAppender applying the policy in your log4j2.xml configuration file.

See the example below:

    <RollingFile name="FILE-ORIGINAL" fileName="${sys:nuxeo.log.dir}/server.log"
                 filePattern="${sys:nuxeo.log.dir}/server-%d{yyyy-MM-dd}.log.gz" append="true">
      <PatternLayout pattern="%d{ISO8601} %-5p [%t] [%c] %m%n" />
      <CronTriggeringPolicy schedule="0 0 0 * * ?" evaluateOnStartup="true" /> <!-- Rollover at midnight every day -->
      <DefaultRolloverStrategy />
    </RollingFile>

    <Rewrite name="FILE">
      <AppenderRef ref="FILE-ORIGINAL"/>
      <MaskSensitiveData />
    </Rewrite>

Disable Tomcat AJP Connector

For security reasons (CVE-2020-1938), AJP is now disabled by default. To re-enabled it, the following properties must be defined:

  • nuxeo.server.ajp.enabled=true
  • nuxeo.server.ajp.secretRequired=true
  • nuxeo.server.ajp.secret=changeme

The secret must also be mentioned in the mod_proxy_ajp configuration, see Apache documentation for more.

If one is sure that the AJP port cannot be accessed by any untrusted hosts, then the following configuration is possible:

  • nuxeo.server.ajp.enabled=true
  • nuxeo.server.ajp.secretRequired=false

 More on JIRA ticket NXP-28703

Allow Some Runtime Configuration in Nuxeo Docker Images

To control the JVM heap size with the new options (since Java 10): InitialRAMPercentage and MaxRAMPercentage, in nuxeo.conf, we've changed:

JAVA_OPTS=-Xms512m -Xmx1024m

to:

JAVA_OPTS=-XX:InitialRAMPercentage=3 -XX:MaxRAMPercentage=25

See the best practices about the Java Virtual Machine Settings for more information.

 More on JIRA ticket NXP-28145

Create ClusterService to Hold Cluster Node Info

When configuring Nuxeo in cluster mode, the configuration is now done with:

nuxeo.cluster.enabled=true
nuxeo.cluster.nodeid=...

You should specify a nuxeo.cluster.nodeid even if you don't activate clustering, as it may help debugging (in particular Stream-based Pub/Sub).

The previous Framework properties (repository.clustering.enabled=true, repository.clustering.id=...) are still available for backward compatibility.

Note that repository.clustering.delay still exists but is only meaningful for VCS when used with the legacy and deprecated JDBCClusterInvalidator (which is not the default anymore since Nuxeo 9.1 (NXP-21801)).

Behavior Changes

Better Tracking of the Nuxeo Health Check Failures Since 2021.2

The unhealthy status are now tracked into the logs at WARN level.

In order to not pollute the log if failures happen for all /runningstatus check, you should put this logger in your log4j2 configuration:

    <Logger name="org.nuxeo.ecm.core.management.statuses.HealthCheckResult">
      <!-- this filter allows to print 1 log (maxBurst) every minute (rate) -->
      <BurstFilter level="warn" rate="0.0166" maxBurst="1"/>
    </Logger>

RemoteIpValve Added to the Tomcat Configuration Since 2021.2

The RemoteIp Valve has been added by default to the Tomcat configuration.

This valve replaces the apparent client remote IP address and hostname for the request with the IP address list presented by a proxy or a load balancer via a request header.

 More on JIRA ticket NXP-25667

Configuration Generator Refactoring Since 2021.2

There're breaking changes on ConfigurationGenerator, a lot of methods has been removed, constants have been removed or moved to ConfigurationConstants.

The new class ConfigurationHolder is the new first citizen to get the Nuxeo Configuration in this layer. You can retrieve it with ConfigurationGenerator#getConfigurationHolder method.

You now can use nuxeo.append.templates.SOMETHING=A_TEMPLATE parameter in nuxeo.conf to append templates to load by the configuration generator.

Strict Mode by Default for nuxeoctl Start

nuxeoctl now starts a Nuxeo server in strict mode by default. --force and --strict have no impact.

To start a Nuxeo server but aborting in error the start command when a component cannot be activated or if a server is already running, use the --lenient option.

$ nuxeoctl start --lenient

Core Storage

Allow Efficient Search by Blob Key Since 2021.2

In order to improve the search by blob key in the existing databases, an index should be added on ecm:blobKeys:

db.default.createIndex({"ecm:blobKeys": 1})

 More on JIRA ticket NXP-29516

Behavior Changes

Adjust the Mongodb Query Maxtime With Transaction Timeout Since 2021.2

The maximum query execution time on MongoDB side is now aligned with the Nuxeo transaction. The configurable maxTime introduced in NXP-29112 is only used when queries are performed outside of a transaction.

Document Creator And Contributors Injection/Impersonation

The following dublincore properties are now secured from edition:

  • dc:created
  • dc:modified
  • dc:creator
  • dc:lastContributor
  • dc:contributors

This means you have to be administrator to edit these properties. In tests, you can do the following:

Framework.doPrivileged(() -> doc.setPropertyValue("dc:creator", "john"));

or:

CoreInstance.doPrivileged("default", session -> {
    DocumentModel doc = session.createDocumentModel("/", "file", "File");
    doc.setPropertyValue("dc:creator", "john");
    return session.createDocument(doc);
});

In order to declare a property secured you can contribute the following:

<component name="my.component.name">
  <extension target="org.nuxeo.ecm.core.schema.TypeService" point="schema">
    <property schema="YOUR_SCHEMA" name="PROP_NAME" secured="true" />
  </extension>
</component>
You can also relax the constraint on a secured property, for example dc:creator with:
<component name="my.component.name">
  <require>org.nuxeo.ecm.core.CoreExtensions</require>
  <extension target="org.nuxeo.ecm.core.schema.TypeService" point="schema">
    <property schema="dublincore" name="created" secured="false" />
  </extension>
</component>

Nuxeo API Changes

New Endpoint to Get All Comments for 50+ Annotations Documents

  • REST API: The endpoint GET /nuxeo/api/v1/id/DOC_ID/@annotation/comments has been deprecated in favor of POST /nuxeo/api/v1/id/DOC_ID/@annotation/comments.

    The annotationIds are now given in the payload request as a simple json array.

    For instance:

    curl -XPOST http://localhost:8080/nuxeo/api/v1/id/DOC_ID/@annotation/comments -d '[ "ANNOT_ID1", "ANNOT_ID2", ...  ]'
    
  • Java API Added:

    CommentManager#getComments(CoreSession session, Collection<String> documentIds)
    AnnotationAdapter#getCommentsFromBody(String payload)
    

    Deprecated:

    AnnotationAdapter#getComments(@QueryParam("annotationIds") List<String> annotationIds)
    

 More on JIRA ticket NXP-29610

Remove "session id" Notion From CoreSession and DocumentModel

New methods:

  • DocumentModel.getPrincipal()
  • DocumentModel.attach(CoreSession)
  • DocumentModel.isAttached()
  • CoreInstance.getCoreSession() various signatures, as replacements for deprecated openCoreSession()
  • CoreInstance.getCoreSessionSystem() various signatures, as replacements for deprecated openCoreSessionSystem()

Deprecated methods/fields/classes:

  • DocumentModel.getSessionId()
  • DocumentModel() constructors with sid parameter
  • CoreInstance.openCoreSession() various signatures (use getCoreSession() instead)
  • CoreInstance.openCoreSessionSystem() various signatures (use getCoreSessionSystem() instead)
  • CoreInstance.closeCoreSession() (does nothing)
  • DocumentModelFactory.createDocumentModel(type, id) (was unused)
  • CoreEventConstants.SESSION_ID (was unused for a long time)
  • CoreSessionService.releaseCoreSession(CoreSession) (does nothing)
  • CloseableCoreSession (use CoreSession instead)

New INTERNAL methods:

  • DocumentModel() constructor with CoreSession, repositoryName, NuxeoPrincipal parameters
  • DocumentModelFactory.createDocumentModel() signatures with CoreSession parameter
  • BaseSession.createEntryModel(schema, id, values, readOnly) and variations (directory class)

Removed methods/fields/classes (these were INTERNAL implementation details):

  • DocumentModel.attach(sid)
  • DocumentModelFactory.createDocumentModel() signatures with sid parameter
  • CoreSession.isLive(boolean)
  • CoreSession.getSessionId()
  • CoreInstance.getSession(sid)
  • CoreSessionService.getCoreSession(sid)
  • CoreSessionService.getCoreSessionRegistrationInfos()

ConfigurationService API

APIs below were deprecated:

  • String getProperty(String) in favor of Optional<String> getString(String)
  • String getProperty(String, String) in favor of String getString(String, String)
  • boolean isBooleanPropertyTrue(String) in favor of boolean isBooleanTrue(String) (same behavior)
  • boolean isBooleanPropertyFalse(String) in favor of boolean isBooleanFalse(String) - new API returns true if and only if property value is false, it wasn't the case for isBooleanPropertyFalse which returns true if property value is not blank and is not true.

Cannot use multi repository (XA mode) with PostgreSQL

The following APIs are deprecated and will be removed in the future:

  • TransactionHelper.suspendTransaction
  • TransactionHelper.resumeTransaction
  • TransactionHelper.requireNewTransaction

Instead, the following APIs should be used:

  • TransactionHelper.runInNewTransaction
  • TransactionHelper.runWithoutTransaction

Operations and Automation

GET Call to an Operation's @async Returns a JSON

Result of a GET call to an operation's @async adapter is now always JSON. Previously when the result of the operation had a URL we returned a redirect to download the file but, in order to workaround the opaque redirect limitation, we are now returning the JSON object with the absolute URL. Clients should follow the URL manually to trigger the download.

Error Management on Invalid Operation/Chain/Codec Registration

Operation chain contributions should now require contributions holding operations that they reference.

The following issue will now prevent server from starting in strict mode:

  • invalid chain declaration, referencing an operation unknown to the service at registration time
  • invalid operation class declaration (class not found or not an operation)
  • invalid automation codec class declaration (class not found or not a codec)

Fn.htmlEscape is Now Available in JS Automation

The following methods become non-static to be available via JS automation:

  • org.nuxeo.ecm.automation.features.PlatformFunctions#htmlEscape
  • org.nuxeo.ecm.automation.features.PlatformFunctions#nxqlEscape

You can use them directly through the Fn object:

var escapedHtml = Fn.htmlEscape(html)
var escapedNxql = Fn.nxqlEscape(nxql)

When used in Java code, you must update your code from:

String htmlEscaped = PlatformFunctions.htmlEscape(html);
String nxqlEscaped = PlatformFunctions.nxqlEscape(nxql);

to:

PlatformFunctions pf = new PlatformFunctions();
String nxqlEscaped = pf.nxqlEscape(nxql);

Make Tests Stop Depending on nuxeo-automation-client

Tests depending on EmbeddedAutomationServerFeature can now make use of a limited-functionality org.nuxeo.ecm.automation.test.HttpAutomationClient (in a new package) that does direct HTTP calls and doesn't attempt to map JSON responses to a domain-level object model like Document, etc.

@Inject
protected Session session;

becomes:

@Inject
protected HttpAutomationSession clientSession;

Rename the Parameter "overwite" of filemanager.import to "overwrite"

In the FileManager.Import operation, the misspelled param overwite has been renamed to overwrite:

  • overwite is now deprecated, no more used and replaced by overwrite.
  • overwite is kept as an alias for backward compatibility.

Workflow

Behavior Changes

Nuxeo Workflow Now Supports 2 Parallel Tasks Completed at the Same Time by 2 Different Users Since 2021.10

A warning is logged when assigning an unauthorized workflow global variable instead of throwing an exception.

Assigning an unauthorized workflow global variable won't throw an exception anymore but log a warning. The assignment is ignored.

 More on JIRA ticket NXP-30589

Cluster-Wide Lock for the Workflow Model Import Since 2021.2

Workflow model import now uses a cluster-wide lock.

This improvement avoids the creation of several workflow definitions at the same time when starting several Nuxeo nodes simultaneously

In cluster mode, the worfklows are initialized non-concurrently in a cluster-wide critical section.

When a cluster node attempts to initialize its workflows and another node is already doing the same thing, it will wait for 1 min for the cluster-wide lock to be released and do its own initialization. If this timeout expires, then initialization fails with an exception.

The following nuxeo.conf properties can be used to change this timeout:

org.nuxeo.workflow.cluster.start.duration=1m

In case where there's a startup crash while a lock is held, it may be necessary to manually cleanup the key/value store of its lock. The key corresponding to the lock is visible when using Redis with KEYS nuxeo:cluster:*, in this case nuxeo:cluster:start-workflows-default for the initialization of the workflows of the default repository. For a MongoDB key/value store, the keys are stored in the collection kv.cluster

Rendition

Behavior Changes

Process Picture Views in a Transaction With a Dedicated Timeout Since 2021.6

Picture views are now processed in a transaction with a dedicated timeout.

The maximum duration to produce the picture views is now limited by default to 5min. This limit is applied to the (deprecated) picture views generation work and also to the recomputeViews bulk action.

The limit can be tuned with:

nuxeo.picture.views.transaction.timeout.seconds=300

 More on JIRA ticket NXP-30369

Add Explicit Timeout on Video Conversion Since 2021.6

The maximum duration to convert a video is now limited by default to 10min.

The limit can be tuned with:

nuxeo.video.transaction.timeout.seconds=600

Note that the limit is set at the transaction level (and not at the command level) because video conversion may involve multiple commands.

Elasticsearch

Elasticsearch client library version is now 7.9.2.

Once you have adapted your application to follow the behavior changes of Elasticsearch 7.x, you need to upgrade your existing Elasticsearch cluster to version 7.9 (7.7 or 7.8 are also supported).

Behavior Changes

Default Elasticsearch Timeout Increased for the Write Operation Since 2021.5

A longer Elastic timeout is used for write operation.

By default, we have changed it from 60 sec to 120 sec.

 More on JIRA ticket NXP-30470

Update Your Custom Elasticsearch Settings and Mapping

If you have a custom configuration for Elasticsearch, it needs to be adapted to follow the new 7.x rules.

Here are a few breaking changes to take into account when upgrading from Elasticsearch 6:

  • If you use the nGram tokenizer the type has been renamed from nGram to ngram.

  • A phrase prefix search on a keyword field now raises an exception, this will happen on the following query:

    SELECT * FROM Document WHERE someKeywordField LIKE 'foo%'
    

    The field needs to be of text type.

If you have to adapt your setting or mapping, you will need to re-index the repository to apply the change.

Don't Use the TransportClient

The connection to Elasticsearch should use the RestClient (default since Nuxeo LTS 2017), the TransportClient is deprecated in version 7.x.

Technically, it can work if the index exists, but re-indexing is going to fail.

There is no advantage of using the TransportClient over the default RestClient.

Warnings in Unit Test with Embedded Elasticsearch Instance

Your unit tests may have the following WARN messages:

2020-11-16 11:10:43,561 [main] WARN  [DanglingIndicesState] gateway.auto_import_dangling_indices is disabled, dangling indices will not be automatically detected or imported and must be managed manually
2020-11-16 11:10:43,828 [elasticsearch[nuxeoTestNode][clusterApplierService#updateTask][T#1]] WARN  [ClusterApplierService] failed to notify ClusterStateListener
org.apache.lucene.util.SetOnce$AlreadySetException: The object cannot be set twice!

You can ignore them by editing your log4j2 test configuration to add:

    <!-- Remove WARN on elastic embedded because dangling indices cannot be detected -->
    <Logger name="org.elasticsearch.gateway.DanglingIndicesState" level="error" />
    <!-- Remove WARN on elastic embedded because node and cluster identifiers change between test suites -->
    <Logger name="org.elasticsearch.cluster.service.ClusterApplierService" level="error" />

Adapt Your Custom Elasticsearch Queries

If you use the Elasticsearch Passthrough, or if you use directly the elasticsearch query builder, make sure your query works in Elasticsearch 7.x.

One of the biggest changes is that the Elasticsearch document type has been removed, for instance, this changes the URL pattern to access a Nuxeo document from http://elastic:9200/nuxeo/doc/<DOC_ID> to: http://elastic:9200/nuxeo/<DOC_ID>.

Make Elasticsearch Hints an Extension Point

Elasticsearch hints are now exposed as extension point. To contribute or override an existing Elasticsearch hint, you should provide a name for your Elasticsearch hint and an implementation of org.nuxeo.elasticsearch.api. ESHintQueryBuilder.

The new way to expose the ES hints is by creating a contribution as below:

  • We add new Extension Point to our existing ESComponent: org.nuxeo.elasticsearch.ElasticSearchComponent
  • The name of XP is elasticSearchHints.
  • At the end our "fuzzy" switch case, will be done like below:
<component name="org.nuxeo.elasticsearch.hint.contrib">
  <require>org.nuxeo.elasticsearch.ElasticSearchComponent</require>

  <extension point="elasticSearchHints" target="org.nuxeo.elasticsearch.ElasticSearchComponent">
    <hint name="match" class="org.nuxeo.elasticsearch.hint.MatchESHintQueryBuilder" />
    <hint name="match_phrase" class="org.nuxeo.elasticsearch.hint.MatchPhraseESHintQueryBuilder" />
    <hint name="match_phrase_prefix" class="org.nuxeo.elasticsearch.hint.MatchPhrasePrefixESHintQueryBuilder" />
    <hint name="multi_match" class="org.nuxeo.elasticsearch.hint.MultiMatchESHintQueryBuilder" />
    <hint name="regex" class="org.nuxeo.elasticsearch.hint.RegexESHintQueryBuilder" />
    <hint name="fuzzy" class="org.nuxeo.elasticsearch.hint.FuzzyESHintQueryBuilder" />
  </extension>
</component>

Upgrade Elasticsearch to 7.x

The procedure depends on when your instance has been created:

Elasticsearch Indexes Created in Elasticsearch 6.x (Nuxeo 10.10/LTS 2019)

Elasticsearch 7.x can read indexes created in version 6.0 or above.

This means that there is no migration to do if your Nuxeo instance has been created with Nuxeo LTS 2019.

Follow the Elasticsearch upgrade documentation to upgrade your Elasticsearch Cluster.

If you had to adapt your Elasticsearch settings or mappings for 7.x, you have to proceed to a repository re-index in order to apply the new configuration.

Migration of Elastic Indexes Created in Elasticsearch 5.x (Nuxeo 9.10/LTS 2017)

An Elasticsearch 7.x node will not start in the presence of indexes created in a version of Elasticsearch before 6.0. Indexes created in Elasticsearch 5.x or before will need to be reindexed with Elasticsearch 6.x in order to be readable by Elasticsearch 7.x.

Nuxeo uses 3 indexes:

  1. The repository index, named nuxeo by default, doesn't need this migration because the repository will be re-indexed in the next step, so, once this index has been backed up, you can delete it.

  2. The sequence index named nuxeo-uidgen will be re-created at startup, so, once this index has been backed up, you can delete it.

  3. The audit index named nuxeo-audit needs to be migrated. Follow the re-index upgrade procedure.

Once the Elasticsearch cluster is upgraded, start Nuxeo LTS 2021 and proceed to a repository re-index.

Bulk Service (Aka "Bulk Action Framework")

Provide Options at nuxeo.conf Level to Tune Bulk Re-indexing Since 2021.8

New options have been added to nuxeo.conf to tune bulk Elasticsearch reindexing.

You now have the following options in nuxeo.conf:

# Bulk Index action, fetching content (bulk/index computation)
elasticsearch.bulk.index.fetch.concurrency=4
elasticsearch.bulk.index.fetch.partitions=12
# Bulk Index action, submitting requests to elastic (bulk/bulkIndex computation)
elasticsearch.bulk.index.submit.concurrency=2
elasticsearch.bulk.index.submit.partitions=8

Where concurrency is the number of threads per node and partitions value fixes the maximum concurrency at the cluster level. Note that partitions value is taken into account only when creating Kafka topic.

Import

Behavior Changes

Initialize Filename With Blob Name in FileImporterContext

If the file name of the FileImporterContext is missing, then it will now be filled with the Blob's file name.

This means that you no longer need to add control to avoid an empty filename outside of the FileImporterContext class, for example see the snippet code below AudioImporter:

// code placeholder
@@ -57,8 +56,7 @@ public class AudioImporter extends AbstractFileImporter {
         CoreSession session = context.getSession();
         Blob blob = context.getBlob();

-        String filename = FileManagerUtils.fetchFileName(
-                StringUtils.defaultIfBlank(context.getFileName(), blob.getFilename()));
+        String filename = FileManagerUtils.fetchFileName(context.getFileName());

Monitoring

Behavior Changes

Tagging for Datadog Metrics

Many metrics names have been renamed in order to support tagging which is necessary for Datadog and Prometheus support.

Visit the documentation for more information.

Metric names updated to use tag but that generates different metric names in Graphite:

# global metrics for all cluster
nuxeo.works.global.queue.scheduled{queue=$queue}
nuxeo.works.global.queue.running{queue=$queue}
nuxeo.works.global.queue.completed{queue=$queue}
# local metrics per node
nuxeo.works.local.queue.timer{queue=$queue}

Metric names updated to use tag but without changing metric name in Graphite:

# local metrics on computation
nuxeo.stream.computation.running{computation=$computation}
nuxeo.stream.computation.failure{computation=$computation}
nuxeo.stream.computation.skippedRecord{computation=$computation}
nuxeo.stream.computation.processRecord{computation=$computation}
nuxeo.stream.computation.processTimer{computation=$computation}

# elasticsearch service metrics timer, service in index, delete, bulkIndex, search, scroll and fetch:
nuxeo.elasticsearch.service.timer{service=service}

# cache
nuxeo.cache.*{cache=$cache}

Authentication, User Management and Permissions

Use a Dedicated Work Queue for ACL Propagation Since 2021.4

A dedicated Work queue is used for ACL Propagation.

You now have options at nuxeo.conf level to use a dedicated queue for DBS read ACL update:

# Queue for DBS Read ACL Update
nuxeo.work.queue.raclupdate.enabled=false
nuxeo.work.queue.raclupdate.threads=4

Nuxeo Streams

Behavior Changes

Keystore Is Now Optional With Kafka SSL Enabled

The SSL keystore is not mandatory for all Kafka setups. Kafka can work with several security configurations independently.

The best way to infer the need for an SSL keystore is to check if its path is set up in the configuration.

 More on JIRA ticket NXP-27904

Namespaces for Stream and Consumer Group Names Stream and Consumer Group Names Have Changed

To upgrade:

  1. Wait for any asynchronous processing to be done, there must be no activity and no error,
  2. Stop the Nuxeo cluster,
  3. Drop the entire Kafka topics or Chronicle Queue directory,
  4. Upgrade the Nuxeo cluster, streams will be created with new names.

Note that custom code is backward compatible and will continue to work even with name without namespace, but names have been enforced and must match:

[A-Za-z0-9][A-Za-z0-9_]*

or you get:

IllegalArgumentException: Invalid name without namespace: 'foo.bar'

WorkManager

Behavior Changes

Support Filtering When Reprocessing DLQ Work Since 2021.4

DLQ works can be reprocessed thanks to new filters.

The RunWorkInFailure operation has been extended to support 2 more options:

  • dryRun: when true displays statistics on Works to reprocess, note that nothing is processed or modified when this option is activated.
  • categoryFilter: a list of Work categories (comma separated) to filter Works that will be reprocessed

Example of invocation:

curl -X POST "http://localhost:8080/nuxeo/site/automation/WorkManager.RunWorkInFailure" -u Administrator:Administrator -H 'content-type: application/json' -d '{"params":{"dryRun": true, "categoryFilter": "elasticSearchIndexing"},"context":{}}'

Web UI - Take Into Account the Commentable Facet

Comments will only be available for document with the Commentable facet.

Note that on 10.10, this check will only be done when setting the org.nuxeo.web.ui.enforceCommentable conf property to true:

<require>org.nuxeo.web.ui.properties.contrib</require>
<extension target="org.nuxeo.runtime.ConfigurationService" point="configuration">
  <property name="org.nuxeo.web.ui.enforceCommentable">true</property>
</extension>

to avoid a breaking change.

Web UI - Leverage Validation Report Client Side and Allow Async Layout Validation

  • Layout validate method can now return a Promise in which case it must resolve to true to validate the layout.
  • Server-side schema constraint violations are now reported at the top of the create and edit form layout.
  • Server-side, you can now trigger a global validation error by throwing the following exception:

Web UI - Integrate Spreadsheet App Code in Nuxeo-Spreadsheet Web UI Addon

Nuxeo Spreadsheet is no longer a marketplace package, it is bundled with Web UI behind a feature flag. To enable Nuxeo Spreadsheet the new configuration property org.nuxeo.web.ui.spreadsheet.enabled should be set to true: <extension target="org.nuxeo.runtime.ConfigurationService" point="configuration"> <property name="org.nuxeo.web.ui.spreadsheet.enabled">true</property> </extension>

Web UI - Fix Selection Toolbar in Ordered Folders

Content distributed to "selectionActions" slot in <nuxeo-results> is no longer wrapped with a <nuxeo-actions-menu>. When overriding the default content be sure to wrap the actions or the <nuxeo-slot> with a <nuxeo-actions-menu> if you want to keep previous behavior.

Web UI - Allow using automation API in nuxeo-page-provider

This introduces a new Web UI configuration property org.nuxeo.web.ui.pageprovider.method which by default is GET but can be changed to POST, in which case search requests will leverage the Automation API.

<extension target="org.nuxeo.runtime.ConfigurationService" point="configuration">
  <property name="org.nuxeo.web.ui.pageprovider.method">POST</property>
</extension>

Miscellaneous

Behavior Changes

Move RequestContext and RequestContextFilter to nuxeo-platform-web-common

RequestContext and RequestContextFilter have been moved from WebEngine to nuxeo-platform-web-common.

They have to be imported from org.nuxeo.ecm.platform.web.common.RequestContext and org.nuxeo.ecm.platform.web.common.RequestCleanupHandler (they were previously under org.nuxeo.ecm.webengine.jaxrs.context).

Maven dependency to add:

<dependency>
  <groupId>org.nuxeo.ecm.platform</groupId>
  <artifactId>nuxeo-platform-web-common</artifactId>
</dependency>

Fix Collections Drawer Refresh When Trashing/Restoring a Collection

The nuxeo-documents-untrashed event payload is now consistent with the other similar event payloads and, instead of having only documents uids, contains the complete documents.

Quota Exception Not Raised When Version Is Incremented

Behavior of quota computation and check has changed for versioning.

Now we compute and check the quotas on the aboutToCheckIn event instead of computing the quotas on the documentCheckedIn one and checking the quotas on the documentCheckedOut one.

Don't Do Orphan Versions Cleanup by Default

Orphan versions cleanup is now disabled by default, and can be re-enabled (if its performance is acceptable) by doing:

<require>org.nuxeo.ecm.core.orphanVersionsCleanup</require>
  <extension point="listener" target="org.nuxeo.ecm.core.event.EventServiceComponent">
    <listener name="orphanVersionsCleanup" enabled="true" />
</extension>

Fix Some Nuxeo Maven Groups

Old groupId:artifactId --> new groupId:artifactId for the following maven modules:

  • org.nuxeo:nuxeo-dmk-adaptor --> org.nuxeo.ecm.platform:nuxeo-dmk-adaptor
  • org.nuxeo:nuxeo-platform-lang-ext --> org.nuxeo.ecm.platform:nuxeo-platform-lang-ext
  • org.nuxeo:nuxeo-platform-lang-ext-incomplete --> org.nuxeo.ecm.platform:nuxeo-platform-lang-ext-incomplete
  • org.nuxeo.binary.metadata:nuxeo-binary-metadata --> org.nuxeo.ecm.platform:nuxeo-binary-metadata

Document.Lock Can Be Call Several Times for the Same User

The behavior of AbstractSession.setLock has been modified to meet the requirement "Document.Lock called twice should not fail".

Now if you try to lock a document locked by you, you will only get your original lock.

 More on JIRA ticket NXP-24359

Document Path Not Available in emptyDocumentmodelCreated Event Context

DocumentModel#getRef behavior has changed when called on a non-saved document. Before it was always returning null, now it may return a non-null PathRef value.

If DocumentModel#getRef was wrongly used to test if a document is saved or not, code must be updated to rely on DocumentModel#getId instead.

Remove Old JDBCClusterInvalidator for VCS

The configuration property repository.clustering.delay is now fully unused (all clustering invalidation propagation is immediate).

The unused class JDBCClusterInvalidator has been removed.

The configuration property repository.clustering.delay is not used anymore, and in the <repository> extension point, the <clustering> part doesn't exist anymore.

(Note that the <clustering> id= and enabled= attributes were removed from the <repository> extension point by NXP-25499.)
