parameter 'TerrainGroundPlane' which defaults to -500.
BulletSim had assumed altitudes never went negative but that is not true. The
ground plane is just a safety net so things wouldn't fall to infinity.
Per http://wiki.secondlife.com/wiki/Tips_for_Creating_Heightfields_and_Details_on_Terrain_RAW_Files#Notes_for_Creating_Height_Field_Maps_for_Second_Life
terrain heights up to 508 are possible on the LL grid (and were available on previous releases of OpenSimulator).
The obvious way to allow both this and equivalent -z values, is to rewiden the internal terrain height storage from short to int.
The memory tradeoff is most noticeable on the maximum 8192x8192 var region (equiv to 1024 normal regions), where it adds 128mb to resident use (128k on a normal region)
This is still better than the double used in previous releases.
This does not affect physics or data storage since they already use float and double respectively.
This may not be the final solution if we actually want to sacrifice -z, >327 or something else.
Relates to http://opensimulator.org/mantis/view.php?id=7076
config option, LogOverloads, to log when a thread pool overload occurs.
This option defaults to "True" because the logging data is useful for
diagnosing threading issues.
This uses an offset of 0.05 on the up vector of the sit orientation, after extensive analysis on
http://opensimulator.org/mantis/view.php?id=7096 and https://wiki.secondlife.com/wiki/Talk:LlSitTarget
This supersedes the previous adjustment in 5b73b9c4 which had been wrongly applied.
The maximum change is about 0.1 with a maximum height avatar.
This patch is all Aleric's work - I am applying manually in order to add these additional notes
This fixes http://opensimulator.org/mantis/view.php?id=7123
Users that use MySQL should change their MySQL configuration to support UTF8. In the config file /etc/my.cnf (Linux) or my.ini (Windows), add these settings:
[mysqld]
character-set-server=utf8
[client]
default-character-set=utf8
And then restart MySQL (on Linux: "sudo service mysqld restart").
This happened because these notifications (the UDP packets) can only be sent to Root Agents. But the notifications were done in OnClientLogin(), at which point the client is still a Child Agent. Since a FireAndForget is used, it became a race condition as to whether the packets would be sent before or after the client became a Root Agent.
To fix this, we now only send the notifications once the client becomes a Root Agent for the first time.
a) This shouldn't have been done because at that point the user is still logged-in to the current grid. b) It's not necessary because the user will soon be logged-out completely. c) And it didn't even work because the MySQL database layer prevents setting the region to 0.
