Hello!
I want to announce the new release version number 1.6 of Fuel, a
binary serialization framework for Pharo that provides extremely fast
deserialization. More information on our home
page<http://rmod.lille.inria.fr/web/pier/software/Fuel>. Again,
I thank ESUG for sponsoring me through the
SummerTalk<http://www.esug.org/wiki/pier/Promotion/SummerTalk/SummerTalk2011>program.
You can download this version in Pharo 1.2.1 with:
Gofer new
squeaksource: 'Fuel';
package: 'ConfigurationOfFuel';
load.
((Smalltalk at: #ConfigurationOfFuel) project version: '1.6') load.
This version does not add any new concrete functionality but has two main
achievements: a performance improvement and a design clean up.
Many changes included in this release are part of a design clean up. They
are a necessary step forward to new functionalities that are coming soon.
They make code more understandable. They enable simpler extension. Happily
they also helped to improve serialization performance by reducing
unnecessary interactions. And it is specially important a bottleneck in
graph analysis stage we have successfully attacked, obtaining great results.
Details:
- Removed explicit references to cluster classes scattered around the
system. For example, in previous versions Float>>fuelCluster has an explicit
reference to FLFloatCluster. This version replaces this by a double dispatch
interaction.
- Clusters: Better reification. Removed annoying IDs. Removed Singleton
instance creation mechanism, now mappers manage uniqueness in a better way.
- Mappers: They were simplified. New mapping machanism inspired on Chain of
Responsibility pattern. The global objects detection has been optimized
considerably.
- Analyzer: Part of its behavior and state has been moved to a new
abstraction called 'clusterization'.
Best regards,
