[Opensim-dev] Old ODE still to keep?

[Leal Duarte]

Hi,

     Changes on Robust <-> regions protocols are a bit rare, and when 
they happen, we try to keep backward compatibility.  But we can't ensure 
there will be no breaking changes in future. In fact some support for 
0.8x regions on 0.9x services, or vice versa will be removed in near 
future, (possible some was already removed).

     So running a 0.9.1.x Snail just for old ODE content on future  
robust version, will be a time limited solution.

     Removing Old ODE, will, for all purposes, remove support for the 
old content made for its specific behavior. Most can be fixed, for 
example correcting vehicle parameters that it did ignore, and give odd 
results on engines that support them, etc... but this basically making 
new content.

     And as i said that old content may also have issues with current 
script code.

      The  possible removal of old ODE will only happen, possible under, 
Yeti release (at least 0.9.2.0), and when it mey help simplify future 
code changes on physics and related Framework.

     We may still have Snail update releases ( at least 0.9.1.1).

Ubit

ps:  current options for physics engines are old ODE, Bullet and ubODE

I could use my own ODE physic moving object  in gimisa5 simulator version 0901 successfully.

Using it in 091 grid would still be possible because of  compatibility between simulator version and grid service version. There is no documentation on that but I know from testing that I can connect and run 0901  simulator version with my updated 091 robust server . This allow me to run gimisa5  under simulator 0901 while connecting it to my grid robust services version 091 .

The result show rather little modification to robust server configuration from these different robust versions which support my own experience.
