[ANN] 3.9a6729

Hi

A new alpha release of 3.9 is available:

http://ftp.squeak.org/3.9alpha/Squeak3.9a-6729.zip

There are some new features, I will try to write some form of report  
about them next week.

I am sure that there are bugs, so please test carefuly.

The big news a Method Property and Pragma Framework (by Lukas, me,  
with lots
of helpful comments and advice and the original tweak method property  
code from Andreas).

The Pragma framwork is now compatible with VisualWorks, but will  
continue to be
usable for Tweak.

The system now saves both the class and the selector in the  
compiledMethod, and
the system was fixed to never search the inheritance hierarchy for  
compiledMethods
in order to find the class or/and selector.

A lot of other small things have been fixed. (e.g. a couple of fixes  
from mantis).

The latest public announcement was for 6722, so here's the changelog  
from then on:

Change Set: BehaviorHashEnh v1.2
Date: 22 June 2004, 16.02.2006
Author: Stephan Rudlof, md

md: added a line to the poscript to uncompactify the MethodProperties  
class. We want to add an instVar for the selector.

Improves the default Object>>hash for Behaviors by installing  
Behavior>>hash. String>>hash has been changed a little to avoid
infinite recursion (without changing its semantics). All is done in  
the postscript.

--------------

-Put back in the simplified Decompiler>>#decompileBlock:
- deprecated #who
- CompiledMethod>>#methodNode now sets Class and Selector for non-
installed
   methods to Object/ CompiledMethod>>#defaultSelector
- refactored ContextPart to not call #who
- refactored ProcessBrowserPlus to not use #who
- refactored ProcessBrowser to not use #who
- simplified CompiledMethod>>#defaultSelector
- String>>#hash now uses identityHasch as initial hash (needed for  
Behavior>>#hash)
- moved numArgs: to Symbol, faster
- add Behavior hash
- simplify CompiledMethod: #defaultSelector, #equivalentTo:, #methodNode
- add CompiledMethod>>#selector:
- add iVarselector to MethodProperties, accessors
- make MethodProperties compact again."

- deprecate ContextPart>>#mclass (use methodClass, like in  
CompiledMethod)
- deprecate ContextPart>>#methodSelector (use #selector, like in  
CompiledMethod)

removed'
- refactor to not call deprecated methods.
- Fast #who part 2: Selector from compiledMethod.
- Forward from ContextPart to method (selector, decompile.)
    no need to search anymore
- installed methods now get selector/class set.
