Changelog

Starting with version 2.0.0 clustering with OrientDB is no longer part of the professional support by Gentics. For high availability setups, it is recommended to use Gentics Mesh SQL.

GraphQL: A regression of missing common and, or, not top level filters has been fixed.

REST client: The configuration now allows adding default parameter provider for query parameters, that should be added to every request (unless overwritten).

Tests: The tests API has been extended to allow tests which do not reset the database between test cases.

GraphQL: In cases of long running GraphQL requests, some other GraphQL requests were queued and executed after the long running request, even if enough workers were still available. The behaviour has been changed, so that GraphQL requests will only be queued, if all workers are currently busy.

Cache: The permission cache has been fixed to always return copies of the actually cached entries.

REST: When requesting sorted data, the permission limitations are violated. This has been fixed.

Core: Creating a translation for the root node of a project always failed with a "Bad Request" error, which has been fixed.

Elasticsearch: A full access to the data backed by ES has been given to the admin users.

Because of a flawed cache invalidation strategy, the project stayed on an old 'latest' branch, even if a new one has been assigned, until the caches are invalidated, or a restart is triggered. This has been fixed.

Cache: A mechanism of reattaching the cached entity to the persistence context has been introduced, allowing implementations of smarter cache policies.

Cache: Because of a flawed cache invalidation strategy, the project stayed on an old 'latest' branch, even if a new one has been assigned, until the caches are invalidated, or a restart is triggered. This has been fixed.

A regression regarding OAuth user filtering has been fixed.

Minor improvements in authentication-related utilities Java API, allowing more control over authentication URL management.

REST client: Improves error handling for WebSocket errors.

REST: The endpoints for invoking a consistency check/repair now have a new query parameter async which allows to perform the action as a background job instead of synchronously. Core: Updating and publishing a node in a single request has been optimized to only create a single new version of the content.

Auth: Synchronization of users, groups and roles from AuthServicePlugin implementations (like the keycloak plugin) has been improved for performance and stability.

Elasticsearch: A possibility of DDoSing the ES with a bulk request of too many items has been eliminated.

GraphQL: When an inexisting language has been requested for a node, the schema info was not loaded as well. This has been fixed.

GraphQL: Fetching of micronode fields has been improved to allow batch loading.

REST: The documentation of the generic parameter fields has been fixed. Now fields works over the Language entities as well, the values are uuid,name,languageTag,nativeName.

GraphQL. Some of (micro)schema fields related queries rely on the target (micro)schema having at least one field, crashing in HTTP 500 otherwise. This has now been fixed.

GraphQL: More test cases for sorting have been added.

Core: Unnecessary uniqueness checks for segment fields will now be avoided, when updating nodes.

GraphQL: The overall performance of GraphQL requests has been improved by caching the GraphQL schemas.

Core: Now it is not allowed to set a new password to an empty or invalid (e.g. spaces) string.

Auth: The unnecessary logging of outdated/mismatched auth token has been removed.

Core: A regression of creation of the named entities has been fixed.

Core: Improve the internal Java API of the list field creation, targeting better batch performance.

Core: Improve the internal Java API for granting and revoking permissions.

GraphQL: referencedBy field fetcher has been refactored for more optimal batch loading.

Tests: Added set of tests of uniqueness of the named entities on a database level.

Core: The cache internal Java API has been presented a new constructor, allowing using the weight instead of entity number for the cache size calculations, as well as some new statistics getters.

Core: Now caches treat NULL as a valid value, instead of a constant miss.

GraphQL: Some more multithreading issues with initialization of GraphQL have been fixed.

Core: Requests to branches failed with an internal error, if monitoring was disabled. This has been fixed.

Core: The new configuration option vertxOptions.orderedBlockingHandlers allows to change the behaviour of concurrent handling of "long running" requests (requests that modify data or GraphQL requests). If the option is set to true (default value) such requests will be run in order (per http verticle) and never concurrently. As a consequence, it may happen that e.g. GraphQL requests are queued for some time if some other requests are currently handled. If the option is set to false, blocking requests will only be queued, if all threads of the worker pool are currently busy.

GraphQL: Performance optimizations of the Elasticsearch-based requests.

GraphQL: When the very first GraphQL Queries (after starting the Mesh instance) were executed in parallel, it could happen that GraphQL execution failed with some internal errors. This has been fixed.

GraphQL: Parent loading has been speeded up by using a batch data loading.

Search: Minor logging changes in the search engine, making it less annoying.

Core: More NPE occurrences during the massive concurrent publishing process have been fixes.

Core: When running in the massive concurrent publishing process, it is possible to run into a race condition when some field containers are already processed while being referenced by the edge, throwing an NPE. This has now been fixed.

Mesh Rest Client: An error has been fixed, which prevented sorting parameters from being passed to the endpoint.

Clustering: Calling cluster specific REST Endpoints on non-clustered instances could cause internal server errors. The behaviour has been changed so that a "Bad Request" error is returned containing a proper error message.

Java Rest Client: After logging in with the login() method, the login token was never refreshed, which caused it to expire after the configured token expiration time (per default 1 hour), even if the client was used to do requests. This has been changed now, so that the login token in the client will be refreshed on every request to mesh.

GraphQL: Link resolving in graphql queries ignored the language tags in the links. This has been fixed.

GraphQL: The metadata request does not crash anymore on the empty (micro)schemas. The new related filter, isEmpty, has been added as well.

Java filter for Node reference content field has been fixed. Native filtering pagination has been improved. Some other minor stability fixed applied.

Plugins: Logging fixed upon false triggering of a warning of inexisting role/group connection.

Core: All named instances have been presented an own cache.

Core: Uniqueness checks for webroot url field values will now only be done, if those values actually change. This will improve performance of e.g. schema migrations, where the webroot url field values are likely to not change.

Core: An internal API for efficient loading of list field values has been added.

Clustering: Due to an incorrect check, it was possible that migration jobs could complete without actually migrating anything, when run in a clustered environment with disabled coordination mode.

Core: Support of database level filtering/sorting has been added to the low level Java API.

GraphQL: Support of database level filtering/sorting has been added. New sort parameter in added for structured sorting, forcing the usage of DB filtering. New GraphQL parameter nativeFilter is added to the selected entity lookup methods, with options NEVER (old filtering is forced), ALWAYS (DB filtering is forced), IF_POSSIBLE (if the requested filter is supported by a DB, DB filtering is used, otherwise filtering is fallen back to the old filter mechanism). Please note that not all the currently existing filters are supported by the DB.

GraphQL: A simplified, native filtering friendly version of regex string operation, like, has been added, accepting wildcards % as a zeroable set of characters, e.g. like: "hello%world" requests filtering in the strings, that start with hello, end with world and have zero-to-unlimited number of any characters in between.

GraphQL: Added new filters for field types: list, micronode, (s3)binary. Added a new experimental filter for referencedBy nodes.

OrientDB: Basic experimental support for OrientDB native filtering/sorting is added. The GraphQL Mesh options has a new preference nativeQueryFiltering with options: NEVER (old filtering, default value), ALWAYS (DB filtering is forced), ON_DEMAND (GraphQL parameter nativeFilter is considered).

Core: The internal check for uniqueness of values in webroot fields has been improved.

Core: An API for permission cache fine tuning (distinct items management) has been added.

Core: The requests to create, update or upsert a node have been extended to allow immediate publishing of the modified/created node and to set role permissions on the node.

Core: The request to upload binary data into a binary field has been extended to allow immediate publishing of the modified/created node.

GraphQL: Link resolving in graphql queries could cause an internal error (due to a DuplicateKeyException), which has been fixed now.

GraphQL: Performance of queries that return large amounts of nodes with link resolving in fields or getting node fields has been improved.

Core: The name of a Mesh user is now forced to be unique on a database level, to prevent creating users with an already existing username. The duplicated username detection mechanism has also been improved.

Monitoring: Calling the /health/ready endpoint while restoring an OrientDB backup would block the request. If too many requests were blocked in this way, Mesh would be considered not live any more. This has been fixed now, during a restore, the endpoint /health/ready will now fail immediately while the liveness status will be maintained.

Monitoring: Failing calls to any /health/…​ endpoints will no longer log the whole stacktrace, since this does not contain useful information.

Core: Migration jobs have been made more robust: Migration jobs will now be aborted, in cases were the storage is no longer ready to be written to (e.g. write quorum is not reached, or the storage is read-only due to insufficient disk space available). A periodic check (interval can be configured via setting migrationTriggerInterval) will continue processing of aborted jobs.

Clustering: when running in CUD coordination mode, the requests to trigger job migration were not delegated to the current master. This has been fixed now.

Core: If a node has more that one INITIAL content for a language in a branch, this can now be repaired with the consistency repair tool.

Docker: Additional command line tools have been added to the Mesh Docker image: rsync, curl, iputils, busybox-extras, tar, nano.

Search: The search endpoints (like e.g. /api/v1/search/nodes) were incorrectly treated as not "read-only", which caused them to fail during a cluster topology change, if the setting cluster.topologyChangeReadOnly was set to true. This has been changed now, the real search endpoints are read-only now. It is important to note, that this does still not apply to the index maintenance endpoints /api/v1/search/sync, /api/v1/search/clear and /api/v1/search/status.

GraphQL: In rare cases, GraphQL statements could "hang" forever, which caused the corresponding worker thread to be blocked forever. This has been fixed now by introducing a configurable timeout.

GraphQL: The graphql library has been updated to version 20.0.

Core: The node migration process has been improved to reduce resources footprint on large workloads, by chunking the data. An additional configuration item content.batchSize has been added.

Core: Corner case of updating the webroot info might throw a false conflict exception, when the segment field value is reset for a schema. This has been fixed.

Core: The OrientDB database as been updated to version 3.2.10.

Rest: The new endpoints /api/v2/…​/rolePermissions allow getting, granting and revoking permissions on entities for multiple roles in a single request.

Core: The core Vert.x library was updated to version 4.3.2.

Clustering: Liveness check now marks an instance as dead, if the event bus did not get its own cluster instance ping within the timeout period, even if the non-cluster ping comes in time.

Search: When using language specific index settings, nodes were incorrectly indexed in the language unspecific index when they were moved or tagged causing the node to be present in both the language specific and language unspecific index. This has been fixed.

Core: Having a binary non-segment field update might break the uniqueness of the segment field value, allowing creation of multiple nodes with the same segment/webroot value. This has now been fixed.

Logging: Remove superfluous error messages for HTTP status 4xx errors. These are logged by the logger handler as warnings.

Docker-Image: The base images have been updated to a newer JDK minor version (11.0.16).

Core: On Elasticsearch index resync the indices for additional languages were deleted, ignoring the actual ES language schema setup. This has been fixed.

Core: The included Mesh UI has been updated to version 1.3.6.

Core: The included Mesh UI has been updated to version 1.3.5.

Clustering: when running in CUD coordination mode, post requests of plugins endpoint were redirected to the master instance. This redirection has been removed since plugins can only modify the graphdb using the mesh rest api.

Core: when an initial admin password is provided with an environment variable, its value won’t be logged anymore.

Core: when a binary file was manually deleted from the file system and the same file was uploaded again through the rest api, the binary upload endpoint was returning a success response even though the binary wasn’t actually uploaded. The file will now be uploaded correctly.

Core: when starting a cluster with the initCluster flag, caches were incorrectly initialized. This could lead to data consistency errors and various validations errors and has been fixed now.

Core: when updating permissions of a role for a given object, only the update permissions for the role were checked. A new check has been added to verify that the user requesting the permissions change has read permission on the object.

Java Rest Client: The classes MeshWebrootResponse and MeshWebrootFieldResponse now extend Closeable and calling close() on implementations will close the underlying response. See Gentics Mesh Java Client for examples of how to properly close the responses.

Core: The included Mesh UI has been updated to version 1.3.4.

GraphQL: all requests to graphql v2 were failing if one of the schemas included an s3 binary field. This has been fixed.

Dependencies: The 'spring-security', 'gson', 'zip4j' libraries have been updated.

S3: A support of S3 fields has been added to the indexing engine.

GraphQL: When a node with the root webpath was retrieved in a specific branch, a permission error was returned, even if user had permission for it. This has been fixed.

GraphQL: The behaviour for getting a single node with version=draft using GraphQL has been changed. Before, if a user had only read published permissions and was requesting a draft node, the node content was returned in case the draft version matched the published version. Now a permission error will be returned without the actual content of the node.

This version contains OrientDB version 3.1.18.

It is now possible to use an external SQL database for data storage as alternative to the embedded OrientDB by using the commercially available Gentics Mesh SQL.

Core: Possible errors during node migrations in branches have been fixed.

Java Rest Client: The new options maxRetries and retryDelayMs can be used to configure automatic retries for requests to Mesh which failed due to a network error. By default retries are disabled. A value of -1 for retryDelayMs will automatically calculate a delay such that all tries are performed in the timespan of the call timeout configured for the Ok HTTP client.

Plugins: Fixes plugin initialization such that plugins that failed to load will cause the liveness probe to return an unhealthy status.

Cluster: The plugin initialization now waits not only for the write quorum being reached, but for the node availability as well, during the startup.

Core: Schema field names are now checked for uniqueness regardless of case sensitivity. This behavior was already enforced in the UI, and is now enforced in the REST API. The check is not performed for existing schemas.

Core: When a project was deleted, its associated version purge jobs were not. This has been fixed.

GraphQL: The behaviour for getting lists of nodes with version=draft using the REST API or GraphQL was inconsistent for nodes, for which the requesting user only had the read published permission. When using the REST API, those nodes were never returned, using GraphQL, those nodes were returned, if they were published and the draft version happened to be identical to the published version. The behaviour when using GraphQL has been changed to be identical to the REST API now.

Rest: The endpoint GET /api/v2/{project}/tagFamilies/{tagFamilyUuid}/tags/{tagUuid}/nodes did not correctly check for the read when called with version=draft, but returned all tagged nodes with read published permission. This has been fixed.

Rest: The endpoint GET /api/v2/{project}/navroot/{path} failed with a 404 error if called with version=published and at least one of the nodes in the node structure was not published. This has been fixed.

Documentation: The misleading image mentions in the Micronode documentation have been removed.

Jobs: Previously jobs were running in a single transaction. This has been changed to use multiple transactions during the migration.

Jobs: Schema, Microschema and Branch jobs are now migrating entites in batches, instead of one at a time. The number of elements in the batch can be configured in the MeshOptions.

Core: Caffeine caching library has been updated to version 2.8.0.

Core: Graphql-java library has been updated to version 12.0.

Core: If a link to a node was rendered from a url field, the path prefix of the used branch was ignored. This has been changed now, so that links to nodes will always contain the path prefix, regardless of whether the link is rendered from a url field or from segment fields.

Core: When the pathPrefix of a branch was changed, node could possibly still be access using the old pathPrefix due to an internal cache, which was not invalidated. The cache will now be cleared when a branch is modified.

GraphQL: The fields hostname, ssl and pathPrefix have been added to the type branch.

Core: The internal cache for user permissions has been optimized.

OrientDB: The included OrientDB version has been updated to version 3.1.18.

Search: When a schema contained a field of type "micronode" or "list" of "micronode" and no "allow", generating the microschema version hash as part of the search index name failed with a NullPointerException. This has been fixed, so that the microschema version hash will now be null in such cases (like if "allow" was set to an empty array).

Core: The default values for the periodic disk quota check have been changed to absolute values: the default for storage.diskQuota.warnThreshold is now 3G and the default for storage.diskQuota.readOnlyThreshold is 1G.

Server: Fixed defined Health-Check in docker container and added a startup-grace period of 60s.

Rest: Many reading request were implemented in a way that they would never be executed concurrently with other reading requests. So would e.g. a long running graphql request cause webroot requests executed at the same time to be queued until the graphql request was done. The behaviour has been changed, so that reading requests will only be queued, if the worker pool has been exhausted.

Core: A periodic check for the EventBus has been added, which can be configured via the configuration settings vertxOptions.eventBus.checkInterval, vertxOptions.eventBus.warnThreshold and vertxOptions.eventBus.errorThreshold. If enabled (which is the default), and the periodically sent ping event is not received within the given error threshold, the Mesh instance which be considered unhealthy (liveness check will fail).

Core: The included Mesh UI has been updated to version 1.3.3.

Plugins: Creating a static handler for files in the plugin’s classpath using the new method RestPlugin::addStaticHandlerFromClasspath did not work, if the plugin directory was configured with an absolute path. Plugin initialization would fail, because the static handler could not be created. This has been fixed by allowing root filesystem access to the static handler, if the plugin directory is configured with an absolute path.

Clustering: When starting an instance of Gentics Mesh with the command line parameter -resetAdminPassword to reset the password of the admin user, starting would fail if the write quorum of OrientDB was not reached. The startup behaviour has been changed now, so that resetting the password is delayed until the write quorum is reached.

Rest: When creating a new user and setting the admin flag to false, this failed if the request user did not have the admin flag set to true. The permission check has been fixed now, so that the admin flag is only required for the requesting user, if the new user should also have the admin flag set to true.

Core: When a project was renamed, deleted and then recreated with the same name, an internal cache was not cleared and caused subsequent errors in calls to the project, until the Mesh instance was restarted. This has been fixed now. The internal caches will be properly cleared.

Rest: The new endpoint DELETE /api/v1/admin/cache will clear all internal caches (cluster wide).

Core: The max form attribute size can now be configured and is set to unlimited by default. This limit became relevant for multipart requests after the update to Vert.x 3.9.12.

Core: The included Mesh UI has been updated to version 1.3.2.

Architecture overhaul

Core: The core Vert.x library was updated to version 3.9.12.

Rest: The endpoint /api/v1/admin/jobs now supports query parameters for filtering (status, type, branchName, branchUuid, schemaName, schemaUuid, microschemaName, microschemaUuid, fromVersion, toVersion).

Search: The periodic check for correctness of the indices in Elasticsearch created temporary indices, which did not start with the installation prefix, and thus were sometimes not cleaned up. The naming of those temporary indices has now been changed to also start with the installation prefix.

Core: The 'commons-codec' libary has been updated. This fixes possible internal errors when parsing uploaded files using tika.

Core: The Jackson libraries have been updated to version 2.13.2.

Core: The Netty libraries have been updated to version 4.1.72.Final.

Security: The 'spring-security', 'jsoup', 'commons-io', 'guava', 'jackson-databind' libraries have been updated.

Cluster: When starting a node with a new version of Gentics Mesh in a cluster, application of the changelog and setting the new Mesh version and database revision was delayed until the write quorum is reached, but not until the cluster topology lock was raised, which could cause a blocked transaction. This has been fixed.

OrientDB: The included OrientDB version has been downgraded to version 3.1.11.

Search: When the ElasticSearch instance is not available, getting version information from the endpoint /api/v1 failed with an internal server error. This has been fixed, calling the endpoint /api/v1 will not fail anymore, but will not contain the ElasticSearch version.

Rest: When a project with name "project" was deleted, calls to the endpoint /projects would cause 404 errors, until the Mesh instance was restarted. This has been fixed now.

Java Rest Client: If requests to mesh fail with I/O errors (including timeouts), the thrown exception will now also contain the request method and URL.

Server: Liveness-Check script live.sh will now fail if the mesh.live file has not been changed since 20s (previously 60s)

Docker-Image: The base image has been changed from JRE to JDK to include more tools for analyzing (e.g. creating heap-dumps). The base image has been updated to a newer JDK minor version (11.0.12)

OrientDB: The included OrientDB version has been updated to version 3.1.15.

Cluster: When doing a rolling update in a cluster, a OConcurrentModificationException could occur during the startup, which could cause subsequent errors. This has been fixed.

Core: A periodic check for available disk space has been added. If not enough disk space is available, Gentics Mesh will be set to read-only to avoid corruption of the storage due to a full disk. Additionally, the metrics mesh_storage_disk_total and mesh_storage_disk_usable have been added to monitoring.

Search: The indices for nodes of a schema, which contains fields of type "micronode" have a mapping for the fields in the allowed microschemas, but were not changed, if the microschemas were changed. This caused subsequent errors while indexing or searching. The naming of such indices have been changed to contain a hash over all allowed microschema versions and when a microschema is changed, a new index will be created now. This update will automatically drop and recreate all existing indices for schemas containing fields of type "micronode".

AWS S3: Now the Cross-Origin Request Settings parameters of a S3 connection can be configured. By default the allowed headers/origins are set to *, the allowed methods are set to "GET", "PUT", "POST", "DELETE". Setting any of the CORS configuration to null prevents is to override the server’s default configuration. Setting all the CORS configuration to null or empty value prevents the CORS config to be changed at all.

Server: added a health/writable monitoring and REST endpoint to check whether mesh is in a writable state (e.g. the topology lock is not hold).

Server: when a schema was updated with a new field with elastic search properties, these were ignored. This has been fixed now.

Search: If ElasticSearch indices, which were originally created by Mesh were dropped, they would probably be re-created with the default mapping when Mesh stored a document in the index. This could cause the index to be not completely filled and also the mapping to be incorrect, so that search queries would fail to find documents. In order to detect and repair such situations, a periodic check has been added to Mesh, which will check existence and correctness of all required ElasticSearch indices. Missing indices will be created and incorrect indices will be dropped and re-created. Afterwards a full sync for the affected indices will be triggered. The check period can be configured with the new configuration setting search.indexCheckInterval, which defaults to 60_000 milliseconds. Setting the interval to 0 will disable the periodic check (not recommended).

Search: The index maintenance endpoints /api/v1/search/sync and /api/v1/search/clear have been extended with the query parameter index, which can be used to restrict the synchronized/cleared indices by a regular expression.

Search: The index maintenance actions triggered via /api/v1/search/sync and /api/v1/search/clear will now be redirected to the current master instance, if the cluster coordinator is used.

Core: The included Mesh UI has been updated to version 1.3.1, containing the language-related improvements and minor bugfixes.

Search: When a full synchronization of the search indices was triggered, language specific indices were unnecessarily removed first. This has been changed, language specific indices will now be treated like all other indices during a full synchronization.

Core: When performing an update for role permissions, an event was published even if the update actually did not change anything. A check has been added to only publish the event if permissions are actually changed.

Core: When eventbus messages where published during execution of a job (e.g. a node migration), the events were not published and handled immediately, but were queued in memory and eventually published after the job execution. This caused high memory consumption during a node migration and also the elasticsearch indexing of migrated nodes to be delayed until after all nodes had been migrated. Execution of the jobs has been changed now, so that events will be published immediately to fix those issues.

Core: The overall memory consumption during a migration job has been reduced.

Clustering: Due to a bug in the vert.x eventbus system, elasticsearch sync operations were not only performed in the Mesh instance, were the causing data change actually happened, but on all Mesh instances, which caused unnecessary high load on the elasticsearch. This has been fixed with a workaround.

Core: When deleting old versions of nodes, the related binaries were not deleted from the disk. This has been fixed now. Credits to https://github.com/kdima001.

Core: When an OrientDB transaction repeatedly fails and runs into the retry limit, the original cause will now also be logged.

Server: When an OutOfMemory was caught or one of the plugins (permanently) failed to initialize, mesh was still considered to be live. This has been fixed now.

Clustering: When doing an offline update of Mesh in a cluster, the first instance of the cluster could not be started with the new Mesh version, because the new version should be written into OrientDB, which failed due to write quorum not reached. The initialization procedure has been changed now, so that executing the changelog and storing the Mesh version and DB revision will now only be started after the write quorum has been reached.

Server: Mesh will now create a file mesh.live and touch it every 10 seconds as long as the instance is considered live. If an OutOfMemory is caught or one of the plugins (permanently) fails to initialize, mesh is considered no longer live and the file will not be touched any more.

Server: The readiness probe will now also check the status of the local OrientDB storage. A mesh instance will only be considered "ready" if the local OrientDB storage is "ONLINE".

GraphQL: The wait parameter will now only wait for elasticsearch to be ready when a query option in nodes is actively used. Previously it would wait for elasticsearch even if it wasn’t needed.

Clustering: When recovering from a split-brain situation, the topology lock (which was raised, because nodes rejoined the cluster) was not always removed. This has been fixed, and some info log about the reason for the topology lock has been added.

Core: The included Mesh UI has been updated to version 1.3.0, containing the stability improvements, as well as the new feature of the node status (draft/updated/published/archived etc) filtering.

Clustering: The high level changelog system has been extended to allow for specific changes to be executed in cluster mode.

Core: A bug preventing the string schema field restrictions from being cleared, has been fixed.

Core: The included Hazelcast-Kubernetes library has been updated to version 1.5.6, containing a DNS resolving fix.

AWS S3: A bug preventing the new image data from being stored into an existing s3binary container, has been fixed. AWS S3: An inability of changing permissions for the schema with an S3 field has been fixed.

Core: Added support for storing/referencing the binary data at Amazon Web Services S3 container.

Clustering: The cluster.topologyChangeReadOnly setting and MESH_CLUSTER_TOPOLOGY_CHANGE_READONLY environment setting have been added. By enabling this flag, Mesh will be automatically set in readOnly mode, when the cluster topology changes, which will let reading requests pass and writing requests fail (immediately), instead of blocking all requests, which happens when the cluster.topologyLockTimeout is set to a positive value.

Plugins: If plugin initialization fails due to topology changes (e.g. the OrientDB needs to be synchronized from another node), the plugin will be set to status FAILED_RETRY and initialization will be retried as soon as OrientDB becomes available again.

Clustering: The timeout for waiting to join the cluster (which includes the time for synchronizing the graphdb storage), which was hardcoded to 500_000 milliseconds, can now be configured with the setting storage.clusterJoinTimeout or the environment variable MESH_GRAPH_CLUSTER_JOIN_TIMEOUT.

OrientDB: The included OrientDB version has been updated to version 3.1.11.

Upload: More user-friendly message + HTTP 400 error on an attempt to upload an empty file.

OrientDB: The included OrientDB version has been updated to version 3.1.10.

Plugins: An issue in the plugin environment has been fixed which prevents plugin REST handler starting over 0.0.0.0 host IP address, when the OS disallows it.

Upload: The document processing library tika has been updated to version 1.26 to fix the PDF parser failing on files with some Adobe fonts.

Core: Added support for looking up the node field content by the webroot path and a field name.

Rest: Added new endpoint for the webroot path field lookup.

Changelog: Fix the failing on-the-fly migration introduced in 1.7.5. The migration was producing ClassCastExceptions.

Jobs: A race condition within the job processing mechanism has been fixed. In some cases newly created jobs would not be automatically invoked. This has been fixed now.

Jobs: New jobs will now set the correct start date and time.

OrientDB: The included OrientDB version has been updated to version 3.1.6.

OrientDB: A bug in the startup order has been fixed which prevented opening of databases via OrientDB Studio.

Core: Binary upload processing failed for binaries with brackets in the metadata key. This has been fixed now.

GraphQL: Queries, that take longer than the configured threshold will be logged now. See GraphQL Slow Query Log for details.

Changelog: The changelog entry that introduces bucket ids which are needed for the differential sync mechanism has been removed. New Ids will now be generated on-the-fly. #1152

OrientDB: The included OrientDB version has been updated to version 3.1.4.

Clustering: The coordination feature will now be automatically disabled whenever clustering is disabled.

Clustering: Internal caches will now be cleared when cluster topology changes occur.

Backup: The ?consistencyCheck query parameter was added to the /api/v2/admin/backup endpoint. When set to true it will run the consistency check before invoking the backup. The call will fail when inconsistencies were detected.

Clustering: An additional check has been added which will prevent nodes from joining a cluster which contains an outdated database. The -initCluster flag needs to be used for a single instance to migrate the cluster. This is done to prevent concurrency issues during changelog execution and cluster formation.

Tests: The path handling for the MeshContainer test container class has been updated. Container data will now be placed in the target/mesh-containers folder.

Additional log output and checks have been added to the auth plugin mapping code. This fix also addresses the Null keys are not supported error which was thrown when handling mappings which provide no group and role names. #1138

OrientDB: The included OrientDB version has been updated to version 3.0.34.

Rest: The webroot cache error handling has been improved.

Clustering: A check for invalid cluster options has been added. The networkHost value can’t be set to 0.0.0.0 since this IP can’t be used for announcing nodes in a cluster.

Core: The link renderer now tries to use url fields to render the link if it cannot be constructed using segment fields.

Search: The memory footprint of the differential sync mechanism has been reduced. The sync operations will now be split into buckets. The size of the buckets can be influenced via the search.syncBatchSize setting.

Core: Fixed a bug that which prevented to update a node reference of a user if the user already had one set. #1114

Core: It is now possible to disable extracting of metadata or content from binaries on a per-field basis. See schema field types documentation for more information.

Plugins: The default plugin timeout has been increased from 15 seconds to two minutes.

Monitoring: The readiness probe will now also check for plugin status. Failed plugin deployments will let the readiness probe fail.

Monitoring: The readiness probe will now no longer fail when a plugin is not registered. Instead it will only fail when a plugin deployment has failed.

Monitoring: The liveness probe will now check for plugin status. Failed plugin deployments will let the liveness probe fail.

Clustering: The webroot handler no longer uses the cluster-wide write lock.

Test: An enhanced test container class has been added. The MeshContainer class replaces the MeshDockerServer which was deprecated.

Elasticsearch: It is now possible to define Elasticsearch settings / mappings per language. This helps using language specific stemmers or stop word lists. Please refer to the documentation for more information.

Core: Fixed a bug that caused an internal server error if a project was attempted to be created after any role with permissions to create projects was deleted.

Java Rest Client: The response body is now properly closed when calling blockingAwait() on a request.

GraphQL: Errors during GraphQL queries are now correctly propagated to the client.

Plugins: The plugin registration process was changed. Plugins will now no longer be directly registered when deployed. Instead the plugins will remain in a pre-registration status until Gentics Mesh is able to deploy them. This is especially useful when running plugins in clustered mode. Plugins will only be registered when the write quorum has been reached. Additionally the plugin deployment process will now utilize a lock in clustered mode to prevent concurrent deployments of plugins. The plugin status was added to the plugin endpoint response.

Clustering: The write lock was removed from the DELETE /api/v2/admin/plugins/:id and POST /api/v2/admin/plugins endpoints to prevent potential deadlocks.

Clustering: The coordinator layer feature will now exclude redirection for requests to the /api/v2/health/live and /api/v2/health/ready endpoints.

Server: Admin users can now always see the serverTokens regardless of the serverTokens setting.

Elasticsearch: Fixed a bug that prevented Elasticsearch synchronization of projects after deleting a role. #1041

Clustering/Graph: The already existing synchronizeWrites feature has been extended. A cluster-wide write lock will now be used when running in clustered mode. This drastically reduces contention. The lock will also be used when new instances join the cluster to prevent synchronization issues with distributed transactions.

Graph: The internal transaction handling has been refactored and unified to better accommodate the new global write lock mechanism.

Clustering: The cluster startup and shutdown processes have been modified to be less error prone. Hazelcast will now be started before OrientDB. Cluster instances now join the cluster sequentially instead of in parallel. This results in a slower but more stable cluster startup process. The shutdown process is now hardened against situations where already dispatched distributed transactions could potentially be lost.

Server: The serverTokens flag and MESH_HTTP_SERVER_TOKENS env has been added to the server config. The flag controls whether server version information is exposed via REST (/api/v1, /api/v2), GraphQL or HTTP headers. By default server tokens are enabled.

REST: Fixed ETag generation when fields or rolePerms was used. Previously these parameters did not affect the ETag. #881

Java Rest Client: Various new methods have been added to handle endpoint agnostic requests (get(), post(), delete(), put()). These methods can be used to handle plugin requests.

Migration: It is now possible to apply schema / microschemaModel changes that include the name property via the changes endpoint. Previously the name property was not utilized.

Core: It is now possible to configure the transaction retry limit using the MESH_GRAPH_TX_RETRY_LIMIT environment variable or the storage.txRetryLimit parameter.

Core: The default value for storage.synchronizeWrites has been changed to true.

Core: The default value for the OrientDB parameter tx.retry.delay has been increased to 10ms, and the constant delay will be used instead of growing linearly. It is now possible to configure the delay via the MESH_GRAPH_TX_RETRY_DELAY environment variable.

Config: It is now possible to override the mapping mode with the MESH_ELASTICSEARCH_MAPPING_MODE environment variable. #878

Core: Various handlers were blocking the event loop when run. This has been fixed now.

Core: Fixed delayed initialization of VersionPurgeJobImpl vertices. Previously the type was not setup during start up and this resulted in a warning when the type was first used.

Core: Schema validation will no longer fail by default, when Elasticsearch is not available. The previous behavior can be enforced by adding ?strictValidation=true.

GraphQL: Fixed a bug that prevented loading of permissions of an element.

GraphQL: Added the rolePerms field to mesh elements. This allows you to load permissions of a role, similar to the ?role query parameter in REST.

Image Manipulation: The new resizing options smart, prop and force have been added.

Search: A new search option search.mappingMode has been added. The mapping mode setting influences how mappings for fields will be generated. By default the mode DYNAMIC is used. In this mode mappings are generated as before. When using the mode STRICT only mappings for fields which have a custom mapping via the elasticsearch schema parameter will be created. This is useful if you want to have finer control of what contents should be added to Elasticsearch.

Graph: The default value for tx.retry.delay has been set to 0. The tx delay will thus be disabled by default.

Clustering: The storage.synchronizeWrites option will be enabled by default when clustering is active.

OrientDB: The included OrientDB version has been updated to version 3.0.23

A regression in v0.38.0 caused migration errors for nodes which contained not yet populated fields. This issue has now been fixed.

Core: Performance of schema migration has been improved.

Search: Two new options have been added to the mesh search configuration. When the encoded request length exceeds the new bulkLengthLimit, no new documents will be added to the bulk and the bulk will be sent to Elasticsearch. The new retryLimit causes Gentics Mesh to drop a request to Elasticsearch after the configured limit has been reached. #784

Search: Backpressure for handling index requests has been improved. This reduces memory usage when indexing large amounts of data in a short period of time. #785

Search: Some default configuration values have been changed. timeout: 8000 → 60000, bulkLimit: 2000 → 100. These changes will not be applied to existing configurations.

REST: Various branch specific internal checks have been updated to fix potential error cases. #787

Core: A bug in the image transform endpoint has been fixed. Previously nodes which were updated using that endpoint could not be found via webroot anymore. #599

Job: The endpoint POST /api/v2/admin/jobs/:jobUuid/process has been added. It can be used to trigger job processing. The endpoint will also automatically reset a failed job to be queued again. The endpoints DELETE /api/v2/admin/jobs/:jobUuid/error and POST /api/v2/admin/processJobs will be removed in a future release. #171

Plugins: A NullPointerException has been fixed which has happened when accessing rc.user().principal() within a plugin. #516

REST: Creating a schema with a micronode field and the allow option set to [] will now allow micronodes of all microschemas. #431

UI: Fixed validation issues in microschemaModel lists when updating nodes. Previously validation issues would not be detected by the UI and the node update would fail. #202

Schema: The container flag in the schema update request is now optional. Omitting the value will no longer cause Gentics Mesh to use the default value false. Subsequently the java request model was altered. The Schema#isContainer method was replaced with Schema#getContainer. Older REST client versions which by default always specified the container flag are still compatible with this change. #165

GraphQL: The permission check for the nodes field of the type Tag has been fixed. Previously loading tagged nodes for a tag did not return the expected result. The published permission for published nodes was not checked correctly. This has been fixed now.

Logging: The default logback.xml file has been updated to include automatic scan of the logging configuration. This change will not be applied to existing configurations.

Schema: It is now possible to reset the allow property of string fields. Setting the allow to empty array will now no longer restrict the values. Instead it will revert back to the original behaviour and allow all values.

UI: Fixed a bug that caused the node list to jump to the first page on various actions. #195

Logging: The conflict error logging has been improved. Conflict error information in the log will now be more detailed and also include the conflicting field key and versions.

Permissions: A bug in the GraphQL nodes field was fixed. Previously branches were not correctly handled and too many nodes would be returned. Additionally the field would not correctly handle the read published permission and also return draft nodes to which no read permission was granted.

Logging: Additional activity information will be logged when the logger for class io.vertx.core.eventbus.EventBus is set to level DEBUG.

REST: Fixed a bug which prevented the DELETE /api/v1/admin/jobs/:jobUuid/error from resetting the job.

Docker: Default memory settings for the server and demo docker images were updated. The -Dstorage.diskCache.bufferSize=256 setting has been added for the server image.

Clustering: The mesh version will no longer be appended to the node name used for OrientDB clustering. It is recommended to sanitize the data/graphdb/storage/distributed-db-config.json file and remove/rename entries which reference older mesh nodes. Only the active nodes should be listed in the file.

Clustering: The default write writeQuorum has been set to majority to increase cluster stability. A writeQuorum of 1 can cause synchronization issues.

Elasticsearch: The Elasticsearch synchronization verticle will no longer be deployed when no Elasticsearch has been configured.

Core: The way editor references are stored has been refactored to increase performance and reduce contention during database operations. A changelog entry will be invoked which migrates the data.

Clustering: Creation of edges which lead to higher contention in the graph have been removed from job’s. Job’s will currently no longer reference the creator.

Search: An error which was thrown by outdated branch schema assignments has been suppressed. A warning will be logged instead.

Search: A potential race condition has been fixed. This condition previously caused the elasticsearch to no longer accept any changes.

Performance: The REST API performance has been improved by optimizing the JSON generation process. #141

Documentation: The new security and performance sections have been added to our documentation.

The Webroot-Response-Type header can now be used to differentiate between a webroot binary and node responses. The values of this header can either be binary or node.

The /api/v2/admin/status/migrations endpoint was removed. The status of a migration job can now be obtained via the /api/v2/admin/jobs endpoint. Successfully executed jobs will no longer be removed from the job list.

The /api/v2/:projectName/release/:releaseUuid/schemas and /api/v2/:projectName/release/:releaseUuid/microschemas endpoint has been reworked. The response format has been updated. The status and uuid of the job which has been invoked when the migration was started will now also be included in this response.

Java REST Client: A potential threading issue within the Java REST Client has been fixed. Vert.x http clients will no longer be shared across multiple threads.

Memory: Reduce memory footprint of microschemaModel migrations. #135

Fixed handling "required" and "allow" properties of schema fields when adding fields to schemas.

Clustering: Added documentation and support for cluster configurations which use a list of static IP adresses instead of multicast discovery.

Node Migration: The node migration performance has been increased.

REST: Added new endpoints /api/v2/admin/jobs to list and check queued migration jobs. The new endpoints are described in the feature documentation.

Search: The raw field will no longer be added by default to the search index. Instead it can be added using the new searchIndex.addRaw flag within the schema field. Please note that the raw field value in the search index will be automatically truncated to a size of 32KB. Otherwise the value can’t be added to search index.

Migration: Interrupted migrations will now automatically be started again after the server has been started. Failed migration jobs can be purged or reset via the /api/v2/admin/jobs endpoint.

Migration: Migrations will no longer fail if a required field was added. The field will be created and no value will be set. Custom migration scripts can still be used to add a custom default value during migration.

Java REST Client: Various missing request parameter implementations have been added to the mesh-rest-client module.

Node Migration: A bug has been fixed which prevented node migrations with more than 5000 elements from completing.

REST: The /api/v2/admin/consistency/check endpoint has been added. The endpoint can be used to verify the database integrity.

Core: Fixed missing OrientDB roles and users for some older graph databases. Some graph databases did not create the needed OrientDB user and roles. These roles and users are needed for the OrientDB server and are different from Gentics Mesh users and roles.

REST: Invalid date strings were not correctly handled. An error will now be thrown if a date string can’t be parsed.

REST: The delete handling has been updated. It is now possible to specify the ?recursive=true parameter to recursively delete nodes. By default ?recursive=false will be used. Deleting a node which contains children will thus cause an error. The behaviour of node language deletion has been updated as well. Deleting the last language of a node will also remove this node. This removal will again fail if no ?recursive=true query parameter has been added.

Core: The permission check system has been updated. The elements which have only readPublished permission can now also be read if the user has only read permission. The read permission automatically also grants readPublished.

Java REST Client: The classes NodeResponse and MicronodeField now correctly implement the interface FieldContainer.

REST: The endpoint /api/v2/{projectName}/nodes/{nodeUuid}/binary/{fieldName} did not correctly handle the read published nodes permission. This has been fixed now. #111

GraphQL: It is now possible to retrieve the unfiltered result count. This count is directly loaded from the search provider and may not match up with the exact filtered count. The advantage of this value is that it can be retrieved very fast.

Java REST Client: The client now also supports encrypted connections.

REST: Invalid date were not correctly handled. An error will now be thrown if a date string can’t be parsed.

GraphQL: Various errors which occurred when loading a schema of a node via GraphQL have been fixed now.

Migration: The error handling within the schema migration code has been improved.

GraphQL: It is now possible to load the schema version of a node using the schema field.

Versioning: Older Gentics Mesh instances (>0.8.x) were lacking some draft information. This information has been added now.

The name field was removed from the content schema and a teaser field has been added. These changes are optional and thus not automatically applied to existing installations.

Demo: The folderName and fileName fields have been renamed to slug. This change only affects new demo installations.

GraphQL: The language fallback handling was overhauled. The default language will no longer be automatically be append to the list of fallback languages. This means that loading nodes will only return nodes in those languages which have been specified by the lang argument.

GraphQL: A language can now be specified when loading node reference fields using the lang argument.

GraphQL: It is now possible to resolve links within loaded fields using the linkType field argument.

Auth: Support for anonymous access has been added to mesh. Requests which do not provide a mesh.token will automatically try to use the anonymous user. This user is identified by username and the thus no anonymous access support is provided if the user can’t be located.

GraphQL: It is now possible to retrieve the path for a content using the path field. The Node.languagePaths has been removed in favour of this new field.

Auth: It is now possible to issue API tokens via the GET /api/v2/users/:userUuid/token endpoint. API tokens do not expire and work in conjunction with the regular JWT authentication mechanism. These tokens should only be used when SSL is enabled. The DELETE /api/v2/users/:userUuid/token endpoint can be used to revoke the issued API token. Only one API token is supported for one user. Generating a new API token will invalidate the previously issued token.

GraphQL: An error was fixed which occurred when loading a node using a bogus uuid.

Auth: An error which caused the keystore loading process to fail was fixed.

It is now possible to resume previously aborted schema migrations via the /api/v2/:projectName/releases/:releaseUuid/migrateSchemas endpoint.

Auth: The Java keystore file will now automatically be created if none could be found. The keystore password will be taken from the mesh.yml file or randomly generated and stored in the config.

Core: Migration errors will no longer cause a migration to be aborted. The migration will continue and log the errors. An incomplete migration can be resumed later on.

Core: Fixed node migration search index handling. Previous migrations did not correctly update the index. A automatic reindex will be invoked during startup.

Core: The schema check for duplicate field labels has been removed. The check previously caused schema updates to fail.

UI: Fixed project creation.

Schema name validation - Schema and microschemaModel names must only contain letter, number or underscore characters.

Node Tag Endpoint

The endpoint /api/v2/:projectName/nodes/:nodeUuid/tags was enhanced. It is now possible to post a list of tag references which will be applied to the node. Tags which are not part of the list will removed from the node. Tags which do not exist will be created. Please note that tag families will not automatically be created.

The tags field within the node response was updated accordingly.

Tags are now also indexed in the node document in the field tagFamilies, grouped by tag families.

The trigram filter configuration was updated so that all characters will be used to tokenize the content.

A bug which prevented index creation in certain cases was fixed.

Names, string fields and html field values will now be indexed using the trigram analyzer.

Binary Endpoint Overhaul

The field API endpoint /api/v2/:projectName/nodes/:nodeUuid/languages/:language/fields/:field was removed and replaced by the binary /api/v2/:projectName/nodes/:nodeUuid/binary endpoint. The binary endpoints are now also versioning aware and handle conflict detection. It is thus required to add the language and version form data parameters to the upload request.

Transform Endpoint Overhaul

The endpoint /api/v2/:projectName/nodes/:nodeUuid/languages/:language/fields/:field/transform was renamed to /api/v2/:projectName/nodes/:nodeUuid/binaryTransform. The transform endpoint will now return the updated node.

A bug within the breadcrumb resolver has been fixed. Previously breadcrumbs did not account for language fallback options and thus returned a 404 path for nodes which used a different language compared to the language of the retrieved node. This has been fixed.

The missing availableLanguages and defaultLanguage parameters have been added to the mesh-ui-config.js file. Previously no language was configured which removed the option to translate contents.

It is now possible to publish language variants. Previously it was only possible to publish nodes. This affected all language variants of the node.

The debug output in case of errors has been enhanced.

The changelog processing action for existing installations was fixed.

Mesh-Admin-UI was updated to version 0.6.13
