New and Noteworthy

Upgrade to Prevent Possible SSL Socket Timeouts

Users proxying https repositories should upgrade. We've fixed a critical issue that caused SSL sockets to never timeout if the remote server started to misbehave. NEXUS-8856

Performance Improvements

We continue our efforts to reduce performance bottlenecks. For example:

  • snapshot removal task speed has been increased by an order of magnitude NEXUS-8724
  • disk space required for the npm metadata database is reduced NEXUS-8737
  • the repository list rendering speed and CPU activity has been reduced significantly for non-admin users. NEXUS-8834

Request Log Now Even More Useful

We have made improvements to the Nexus request log to allow better auditing of request activity.

  • in certain cases, the authenticated user making the request was not logged - this has been fixed NEXUS-7860
  • elapsed time is now recorded as the last field of the log pattern format - this can help identify particularly slow requests NEXUS-8913
  • the request.log is archived with a more compatible name: request-YYYY-MM-DD.log.gz, instead of request.log.YYYY-MM-DD.gz NEXUS-8737

Outbound Storage Requests From Nexus Can Be Easily Monitored

A special logger named has been available for a while at DEBUG level to help identify the requests Nexus makes to other proxy repositories. Now this logger logs before and after the request, includes the response status, elapsed time, and any redirect information. NEXUS-8855, NEXUS-8837
