Release Notes/Second Life RC Magnum/13

13.04.05.273580

• This is a server HTTP improvement project
• Scheduled 2013-04-10, for RC Magnum, RC BlueSteel, and RC LeTigre
• Features
  • More complete and more correct headers on texture and mesh fetches.

    The asset fetch responses, involving texture and mesh fetches, are fairly straight forward. More headers and correct headers will be returned. Viewers will begin to receive the following:

    • Age
    • Cache-Control
    • Content-Encoding
    • Content-Language
    • Content-Length (for meshes)
    • Content-Range (for 206 responses)
    • Content-Type
    • Etag
    • Expires
    • Last-Modified

    The 'Content-Type' for assets will start showing as image/x-j2c and application/vnd.ll.mesh for images and meshes, respectively. Old service behavior will still be present on the grid for a time. And as with HTTP in general, any of these headers may disappear or change in structure or meaning as permitted.

  • Keepalive connections for some HTTP-based services

    The behavioral change for HTTP connections marks the beginning of support for persistent (keepalive) connections. Services transiting the capabilities router, at ports 12043 and 12046, may honor a request for keepalives and keep a connection open after request completion. These services may include such activities as texture and mesh fetching, event delivery to viewer, HTTP-In for LSL scripts, asset uploads and inventory operations. Benefits from keepalives include immediate and future throughput increases and less TCP connection churn (which often disrupts consumer-grade networking equipment).

    The exact set of services that will see this is expected to change over time.

• Changes since 13.04.01.273298
  • Fixed a crash mode

13.02.08.270166

• This is the interest list improvement project
• Scheduled 2013-02-13, for RC Magnum
• Features
  • Less lag for very crowded regions:
    • Faster sorting of visible objects.
    • Faster construction of ObjectUpdate packets
  • Less bandwidth:
    • Fewer update packets for moving objects that are out of view.
    • Fewer updates for for wind data.
    • No more cloud update packets (affects only 1.23 viewers) for legacy cloud sprite distribution.
  • More correct object updates:
    • Improved sorting of objects near to far.
    • More correct object bounding volumes used for server-side culling.
    • More correct camera position for server-side culling.
    • More correct visibility checks for VERY BIG objects (>32m diameter bounding sphere) that are near limit of viewer draw distance.
  • KillObject messages sent for ALL objects in the region upon deletion, whether the server thinks they are visible on the viewer or not.
  • Less frequent wind variation
• Bug Fixes
  • Fixed a bug where some regions would fail to send some object update messages to some viewers, in cases where there was a sudden burst of changes and the scene was still in the process of downloading static objects (BUG-655)
  • Fixed a bug that would cause some "out of view" moving objects to stop getting updates thereby causing their motion to be incorrectly extrapolated into the camera's view. There may still some occurrences of the bug, but it has been greatly reduced (PATHBUG-183)
  • Fixed a bug on region crossing that would cause the viewer to cease getting updates from the recently departed region and would cause the region to "disappear" momentarily about 50 seconds after departure (BUG-141)
• Fixes since 13.01.17.269162
  • Fixed an issue in which certain users experienced high packet loss, leading to unpredictable results in-world (objects and avatars not appearing, etc.)
• Changes since 13.01.28.269574
  • Fixed an issue in which the simulator was losing UDP ACKs in zero encoded messages, which lead to high bandwidth usage in certain libOpenMV bots
  • This release includes the infrastructure to support Normal and Specular maps. The next step is to release a project viewer, which will allow users to try out this new functionality. We will post on the Project Viewer page, the Tools and Technology Blog, and STORM-1905 once this project viewer is ready.
