Upgrade from LTS 2019 to Nuxeo Platform Cloud 2020

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 Cloud 2020 (11.x). We strongly encourage you to also have a quick read of the upgrade notes.

Prerequisites

This upgrade notes assumes 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

Recommended Changes

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)).

 More on JIRA ticket NXP-25499

Behavior Changes

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

 More on JIRA ticket NXP-20418

Simplify Install Packages Script

To simplify the installation of packages while building a Docker image, we have merged both install-packages.sh and install-local-packages.sh scripts into only one install-packages.sh that will handle both packages from Connect and from local packages while offline.

FROM <DOCKER_REGISTRY>/nuxeo:<TAG>
...
# Install a local package without its dependencies (`mp-install --nodeps`)
RUN /install-packages.sh --offline $NUXEO_HOME/local-packages/local-package-nodeps.zip
# Install remote packages and a local package with its dependencies
RUN /install-packages.sh --clid ${CLID} --connect-url ${CONNECT_URL} nuxeo-web-ui nuxeo-drive $NUXEO_HOME/local-packages/local-package.zip
...

 More on JIRA ticket NXP-29825

Chrome SameSite Cookie Configuration

This introduces a new nuxeo.server.cookies.sameSite configuration property which allows setting the same site cookie policy.
In 10.10 this property is unset by default so we don't introduce a breaking change but in newer versions the default value is "strict".

When setting the same site cookie policy to none to allow sending cookies cross origin, these will be automatically set to be secure since this is a requirement and as such the server needs to use HTTPS.

Increase of the Default Number of Partitions for Bulk Action and StreamWorkManager Queues

The default number of partitions is increased for Bulk Action and StreamWorkManager queues (from 2 to 6).

Core Storage

Behavior Changes

MongoDB Repository Configuration Descriptors

Contributions including a MongoDB nativeId, sequenceBlockSize or childNameUniqueConstraintEnabled are now correctly merged.

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)

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)

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

Fix HTTP Status for Batch Upload's "Resume Incomplete"

When doing a:

POST /nuxeo/api/v1/upload/{batchId}/{fileIdx}

to upload a chunk (i.e., with header X-Upload-Type: chunked), the server will now return 202 instead of 308 when not all chunks have been uploaded.

The same applies to:

GET /nuxeo/api/v1/upload/{batchId}/{fileIdx}

which gets the status of an upload.

 More on JIRA ticket NXP-29796

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.

Operation Document.AddPermission "users" Field Now Supports Stringlist

Document.AddPermission operation use now StringList type for users field.

 More on JIRA ticket NXP-26773

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.

Elasticsearch

Since Nuxeo 11.4, Elasticsearch client library version 7.9.2 is used.

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

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.

Import

Behavior Changes

Initialize Filename With Blob Name in FileImporterContext

Since 11.1 if the file name of the FileImporterContext is missing then it will 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}

Change Default Datadog Poll Intervar to 1min

The option to configure the metrics poll interval for Datadog is now metrics.datadog.pollInterval and default is 60 (previously datadog.pollinterval=10)

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'

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:

  throw new DocumentValidationException("your.error.message");
  

in a synchronous listener on aboutToCreate or beforeDocumentModification. Note that your listener must bubble the exception to prevent the creation or modification. The error message of the exception will be translated Web UI (client) side and reported at the top of the create or edit form.
