Config Group Question
September 30, 2005 09:15 AM
Hello again Angel friends
I am trying to use the ConfigGroup to allow the reuse of a variable name "control" with different type.
I am in front of a problem that is when i try to remove the config group declaring this variable, i get the error code CONFIG_GROUP_ALREADY_IN_USE.
I use it like this:
I guess that AS keep the compiled code but how can i manage that?
Thanks for help.

I'm sure that you receive an error message when calling RemoveConfigGroup(), stating that the group is in use. You'll have to make sure that all script code and any variables depending on the config group is removed first.
You can discard the script code by calling Discard() for the module. If that isn't sufficient, you may also want to call GarbageCollect() to remove variables that are no longer used.

Yes i get the error in removing the group.
So I tried as you said to add
engine->Discard(NULL); // as i execute in NULL Module
engine->GarbageCollect(true); // with and without this line
after each call of my executeString(NULL,cmd) Function.
And now i get a crash on the second redeclaration of the global Var (after the removing and recreating of the group)
in RegisterGlobalProperty on this part:
When i remove the Discard it don't crash but the var is sometime not redeclared as i explain before.
I put here my log if it can be of any use:
As you can see in the log i register exactly the same Var Panel (with same pointer) because the two control are on the same panel.
I am stuck :(
Should i use the SetConfigGroupModuleAccess function or is the config group accessible by default?
PS: Humm i see that in the doc so it should goes well, isn't it?

It looks like a bug in AngelScript. I'll look into this as soon as possible.

Thanks you very much WitchLord.
I will post back if i find something on my side.

I had a dive in AngelScript Code to see what could goes wrong and find that:
So you delete the globalProp in the engine that is the same that the globalProp in the configGroup.
Perhaps i am wrong but when you delete the engine globalProps, shouldn't you change the lenght var for the asCArray globalProps and put the last element in place of the deleted one.
Because i cannot see in the code the update of the lenght anywhere.
And apparently what happens in my case is:
Register Prop[0]
Register Prop[1]
Begin ConfigGroup
Register Prop[2]
End ConfigGroup
Remove Group ( Prop[2] =0 )
Register Prop[3] There it should perhaps register Prop[2] again because it was removed.
( and crash when update all pointers because it do that:
*Prop[0]->type.IsObject()
*Prop[1]->type.IsObject()
*Prop[2]->type.IsObject Crash because NULL pointer
It seems to be the same for systemFunctions... and the other asArray.
Hope that helps.

void asCConfigGroup::RemoveConfiguration(asCScriptEngine *engine){ assert( refCount == 0 ); asUINT n; // Remove global variables for( n = 0; n < globalProps.GetLength(); n++ ) { for( asUINT m = 0; m < engine->globalProps.GetLength(); m++ ) { if( engine->globalProps[m] == globalProps[n] ) { delete engine->globalProps[m]; engine->globalProps[m] = 0; } } }So you delete the globalProp in the engine that is the same that the globalProp in the configGroup.

You may very well be correct about this.
This is obviously a scenario that wasn't tested when I implemented the configuration groups. I'll add some new test cases to cover these scenarios and make sure that they are all working.
Thanks for taking the time to figure out what's going wrong.
