Hi everyone, I'm using Alien libraries in Pharo 1.1 and I'd like to use this one in Pharo 1.2 (Cog VM) but I don't know what classes has been deprecated, where can I found information about it? Best Regards, Patricio Inicio del mensaje reenviado:

Hi Eliot,
Regarding to deprecated Alien class libraries how can I get information about the changes between Pharo 1.1 and Pharo 1.2?
Cheers,
Patricio

But I'm hoping that the ALien callouts will die the death soon. I have Alien callbacks integrated with the FFI and of course the ALien data manipulation code works fine. So if you're eager to have Alien callouts work see whether the above change fixes things, in which case I can integrate the fix. But if you're not so eager you could wait for me to push out the FFI changes, but that could take a few weeks.
What exactly does "Alien callouts will die" mean? Does it mean that the Alien class library is deprecated and will be replaced by a new version of FFI? Or is it something else?
It means what it says; that the callout primitives in Alien will die and all the rest will remain. FFI callouts will accept Aliens and, because they have type information, render the Alien call-outs redundant and problematic. The Alien data representation and callback facilities will be retained.
I am close to releasing JNIPort for Pharo/Squeak. I am currently using Alien for interfacing to the Java VM, and with the exception of callbacks from the JVM to Smalltalk which come from foreign threads, everything works now on the Squeak VM ("foreign" callbacks still crash the VM which outputs "scheduler could not find a runnable process" to the console).
I would be a bit unhappy if I had to dump this work and redo the interface to the JVM, and I wouldn't be happy at all if I had to use different class libraries for calling foreign functions depending on the VM (Cog vs. Squeak VM). So, what's the "official" plan for Alien/FFI?
