[F-Script-talk] Block as NSThread target

[Joerg G. <jg...@cs...>]

Hi,
what is the right way to make a new thread with an FScript block as 
target?

The problem with
NSThread detachNewThreadSelector:#value: toTarget:myBlock 
withObject:someObject.
is that there is no NSAutoreleasePool in Place for the execution of 
myBlock.

So myBlock must be shielded by some initialization:
NSThread detachNewThreadSelector:#value: toTarget:(makeThreadableBlock 
value:myBlock) withObject:someObject.

Is there a really good implementation in FScript for this?

makeThreadableBlock:=[:innerBlock |
   [:arg ||p|
     p:=NSAutoreleasePool alloc init.
     innerBlock value:arg.
     p release.
     ]].

yields an error, because NSAutoreleasePools may not be retained (by 
assignment to p). So no assignment? But how to empty the pool then?

makeThreadableBlock:=[:innerBlock |
   [:arg ||p|
     NSAutoreleasePool alloc init.
     innerBlock value:arg.
     ]].

but even the following does not catch all of the autoreleases (see 
console warnings)

makeThreadableBlock:=[:innerBlock |
   [:arg ||p|
     p:=NSValue valueWithNonretainedObject:(NSAutoreleasePool alloc 
init).
     innerBlock value:arg.
     p nonretainedObjectValue release.
     ]].

Any other solutions? Or should the Block method
-(id) valueArgs:(id*)args count:(unsigned)count
contain NSAutoreleasePool initialization and termination?
