Hi,
Based on feedback by Norbert Hartl, Stuart Herring and Dale Hendrichs (thank
you) I improved the current STON version a bit.
http://ss3.gemstone.com/ss/STON
https://github.com/svenvc/ston
Changelog:
A nasty cycle bug was fixed
Performance was improved, especially for large structures.
Some implementation changes (recursion done using a stack,
stonProcessSubObjects: optimized using stonContainsSubObjects)
I did some stress/performance testing/tuning. Using
STONTestMap classTreeExtended.
to generate a structure mimicing the class hierarchy, with objects for all
classes, about 7000 in my image and all methods, about 64000 in my image, with
super/subclass and method owner links to create cycles. This results in a 7 Mb
.ston file.
The normal code, serializes this in 28 seconds and materializes it in 11.5
seconds.
The 'fast' versions (using ZnBuffered[Write|Read]Streams and Fuel Large
Datastructures) does it in 1.1 and 3.8 seconds respectively.
New users are always welcome.
