Can we make prim 118 support mirror logic?

It used to work. In the Spur VM we shipped with Squeak 5.0 it works. The VM sources are from Feb 5 2015.

With a recent VM, the primitive fails, indeed.

Hi Denis,

In the VM the comment for primitive 118 is the following:

"Implement either ProtoObject>>tryPrimitive: primIndex withArgs: argArray

or Context>>receiver: anObject tryPrimitive: primIndex withArgs: argArray.

If this primitive fails, arrange that its error code is a negative integer, to

distinguish between this failing and the primitive it invokes failing."

So mirror logic for primitive 118 should already be supported.

However when I try it...

Mirror new receiver: 20 tryPrimitive: 1 withArgs: { 22 } => primitive failed

20 tryPrimitive: 1 withArgs: { 22 } => 42

So I think it's a bug that should be fixed.

Thanks for reporting.

Hi.

Right now prim 118 is probably only reflective call which not support mirror logic.

It named #tryPrimitive:withArguments:. And it fails when it is called with receiver as first argument.

Can we add support for it?

The reason why I ask is because now any proxy should define this method to support debugger.

Best regards,

Denis
