Release Notes 3.2.77

Publication Date: May 13th 2022

The following are the new features, enhancements and fixed issues for Cloud CMS 3.2.77 release.

Upgrade Considerations

Please review the upgrade considerations provided here: https://www.cloudcms.com/documentation/docker/upgrades/3-2-77.html

Enhancements

Binary Storage

• Enhancements to how binary files are stored to make more efficient use of bulk copy and write.
• Binary Storage operations now log more efficiently and with greater detail.

GraphQL

• GraphQL was refactored to make use of purely asynchronous, non-blocking IO. The result is faster implementation of the GraphQL API that features lower CPU utilization and lower memory requirements.

Java Driver

• Added `driver.setPaths()` and `driver.getPaths()` methods to make it easy for customers to enable the acquisition of path information on API calls that return nodes or node result maps.
• Renamed the `archive.publish()` method to `archive.markAsTemplate()` so as to be forward-consistent with Cloud CMS 4.0.
• Renamed the `archive.unpublish()` method to `archive.unmarkAsTemplate()` so as to be forward-consistent with Cloud CMS 4.0.

Server-Side Scripting API

• Added a `branch.getRootNodeId()` method to retrieve the root node of a branch.
• Added a `node.getPath()` method to retrieve the path of the node relative to the root node of the branch.

Transfer

• Several improvements to make transfer (both export and import) much faster.
• Enhanced the management of H2 DB file handles to ensure that file handle leaks do not accrue for cases where an error might prematurely end a transfer job.
• Deployment Handlers are now entirely asynchronous, allowing for faster execution, more advanced scheduling of work items and higher job throughput.
• Greatly reduced the number of potential refresh() calls required after importing content with relator properties.
• Several graph metrics (such as distance from source) are now computed and cached on the fly, allowing for much faster export times.

Traversal

• The Traversal API code paths were optimized to make retrieval faster and also much less intensive in terms of CPU utilization and heap allocation.

UI Clustering

• Made it easier to configure Redis as a back end for clustered UI servers. Now only requires a single `CLOUDCMS_REDIS_URL` environment variable and an optional `CLOUDCMS_REDIS_DEBUG_LEVEL` variable to globally configure Redis log level. For more information, see: https://www.cloudcms.com/documentation/appserver/clustering.html#configuring-redis
• Updated the QuickStart samples to use an updated version of Redis and demonstrate UI clustering more effectively.

User Interface

• Added a 15 second TTL to static resources retrieved via the `/preview` route. The result is faster execution with less API traffic.

Bug Fixes

ACL Checks / Filtering

• Fix so that ACL checks and filtering are applied universally to all internal methods that allow for field-level selection or partial result set generation.

Branches

• Fix so that branch aliases can be used as identifiers when changing a node's QName.

Job Dispatching

• Fix so that that start time of a job is not errantly overwritten for jobs that transition into and out of an AWAIT state.
• Fix so that job decommissioning makes at least three passes and independent checks before declaring a job out of service.

MD5

• Fix so that dynamic MD5 calculations do not buffer into memory.

Transfer

• Fix so that the `deploy` job (and others) no longer use a synchronous timeout block. This was causing some jobs to fail in an ERROR state (even though the actual export or import eventually did run just fine). All deployment-related jobs are now purely asynchronous and utilize the job AWAIT state to passivate activity until one or more child processes complete.

User Interface

• Fix so that list pages properly teardown event handlers/hooks when the DOM is destroyed or transitioned. The result is faster page rendering and transitioning with less API traffic and a lower number of HTTP requests from the browser.
• Fix so that Branch Picker pagination works as intended.
• Fix so that the Project Stack page retrieves and displays all data stores.
• Fix so that the Project Applications list paginates as intended.
• Fix so that the Node Versions page properly paginates for cases where the last key was being errantly determined.
