Nexus Repository 3.39.0 Release Notes

Release May 23, 2022

Highlights in This Release

Improvements to Blob Store Reconcile Task

Database backup tasks will no longer interrupt a long-runningRepair: Reconcile component database from blob storagetask.

View Nexus, Audit, Cluster, and Task Logs in User Interface

You can now view nexus, audit, cluster, and task logs via the log viewer in the Nexus Repository user interface.

What's New in This Release?

Improved Resiliency/Disaster Recovery for File Blob Stores

File blob stores shared between multiple repository instances in an active/passive resilient deployment can now make use of the Only Blobs created since X days ago option. This was previously impossible as the reconciliation log was stored locally in the active instance, but this has now been moved into the blob store to make it accessible to the passive instance after failover. This improvement decreases failover times by reducing the time it takes for the reconciliation task to complete.

Note that, on a fresh run (i.e., no existing sonatype-work directory), the reconciliation log for newly uploaded blobs is placed in a <blob store root dir>/reconciliation folder. When launched with an existing sonatype-work directory, the upgrade job migrates the reconciliation logs from ${karaf.data}/log/blobstore/${blobstore}/ to <blob store root dir>/reconciliation.

To use this improvement, you must have the Repair - Reconcile component database from blobstore task configured and run the task when the passive instance starts up using the v1/tasks/{id}/run REST endpoint as part of your failover automation.

Note

This improvement only applies to file blob stores; the reconciliation log is not implemented for S3. This also means that this improvement does not apply to our newer resiliency model that relies on S3.

Prevent Blob Store Reconcile Task Interruption

We have made changes to prevent a database backup task from interupting a long-running Repair - Reconcile component database from blobstore task . Interruptions previously caused administrators to need to run the reconcile task again. The database backup task will no longer run if a reoncile task is in progress. If needed, you can stop the reconcile task in order to run a database backup.

View Audit, Cluster, and Task Logs in User Interface

We have extended the log viewer to allow users with with the nx-all privilege to view audit, cluster, and task logs along with the nexus log through the user interface. You can access logs at AdministrationSupportLogs.

For more information, see our newly revamped logging documentation.
