It makes use of the old ByteCodeGenerator from NewCompiler, can't remember why at the moment.. WriteBarrier generates overriding methods for all mutating methods of a class. They capture the pre-state of all modified vars, call super, then check the post-state of the vars and, if different, sends #modified: to the handler.... Something like that. I'm sure it could be updated to not use ByteCodeGenerator, I just haven't had time to do it.. - Chris On Tue, Jul 6, 2010 at 2:25 PM, Stéphane Ducasse <stephane.ducasse@inria.fr> wrote:
What is missing to make it work in Pharo?

Thanks, I will look for your updated WriteBarrier package to include with the next Magma. Â I have just copied my own latest WriteBarrier to the MagmaTester project of squeaksource.

WriteBarrier unfortunately doesn't work in either of Pharo or Squeak 4.1+. Â I am tempted to remove it from the suite altogether, but to do so would break backward compatibility with 3.9 who may be using WriteBarrier, because the implementation requires the handler (MaTransaction) to inherit from the WriteBarrier class itself..

Hi Avi,
how is life at Twitter ;)
Would it be possible that you add me as a developer on
http://www.squeaksource.com/WriteBarrier
so I can clean up underscore assignment in the package.
WriteBarrier is used in Magma (see ConfigurationOfMagma) which is installable right from a workspace in the upcoming Pharo 1.1 release. Currently this fails since by default underscore assignment is not allowed in Pharo.
