Hi all, I am *experimenting* with the replacement of the current network layer with OCEAN. My current plan is to make Zinc tests green while working on the top of OCEAN. And investigate the removal of all the current Network classes (does it play?). After looking at Zinc code, there are few dependencies. Basically, I implemented an OCNSOcketStream (inheriting from SocketStream) and redefined some methods of ZnNetworkingUtils. It seems to play so far (green tests). But then, I discovered that Zodiac introduces a new SocketStream hierarchy (ZdcAbstractSocketStream). Now remember the mails of Sven. So my questions are: 1) Is the intent of ZdcSocketStream to be a future replacement for SocketStream? 2) why ZnNetworkingUtils>>initialize makes use of SocketStream instead of ZdcSocketStream? why the code isn't something like that: ZnNetworkingUtils>>initialize super initialize. self socketStreamClass: (Smalltalk globals at: #ZdcSocketStream ifAbsent: [ SocketStream ]) . self secureSocketStreamClass: (Smalltalk globals at: #ZdcSecureSocketStream ifAbsent: [ nil ]) Moreover, I guess that ZdcSocketStream should speed up things (it says optimized version in the name of the superclass ;-)). So probably, my OCNSOcketStream should better inherit from ZdcSocketStream. Thanks for giving me some light here, Luc
