[Opensim-dev] [Gridnauts] heads up: recent secondlife client versions don't support OSSL functions

[Michael Wright]

Far far from being ideal but as a short term hack to get the os fuctions working again, I guess we could have people putting stub functions at the top of the scripts for the os functions, and then when we get the script on the serve, r remove those stubs. 

So at the top of the lsl script on the client there is :

string osSetDynamicTextureData(string dynamicID, string contentType, string data, string extraParams,  int timer)
{
 return "";
}

and the first step in our script compiler is to look for those prototypes and remove them. 

As I said its a far from being a good solution, but should work for now?

implement LSL functions themselves server-side which do not start with either the ll or os prefixes.
