Include Cryptographic Primitives In VM's - DESPlugin

Hans-Martin did some testing and as we expected the performance of pure squeak cryptography is disappointing:

The DESPlugin is already a part of the VMMaker, I am asking the VM group to please include the DESPlugin in the base VM that is distrubuted.  We will be submitting more code and will follow the process of code -> VMMaker -> VM.  If the VM team wants to wait before building a new VM's until other primitives are available, that is fine, but if a build is going to be done anyway for other issues, please include the DESPlugin.

 

Thank you for your help!

Rob,

 

Thank you for that clarification.  I thought that it was already included.  

 

Tim,

 

Since it is not part of the VMMaker can we have it included?  What specifically do you need from us to make this happen?  Does the plug-in need to be pulled out of our code and submitted separately?  I attached an .st file of the plug-in.

 

Ron

Ron, I don't believe the DESPlugin is part of VMMaker. It is part of our DES package and it is confused about it's superclass. Steps to get the DESPlugin into an image with VMMaker:

 

1) take 3.7 image, which has VMMaker loaded.

2) load Cryptography package from SqueakMap (no Monticello in 3.7)

3) respecify the superclass of DESPlugin to be InterpreterProxy.

4) run VMMaker and generate plugin

 

The 3.8/3.9 image has no VMMaker in it and the VMMaker on SqueakMap is in an inconsistent state.

 

I hope this helps,

Robert

Ron,

That fileout has ProtoObject as the superclass, that needs to be replaced with InterpreterPlugin, I believe is the correct superclass - not InterpreterProxy.
