With the team at Bordeaux, we are working on an
implementation to query histories (the tool is named VPraxis).
Which kind of query are you interested in? Is Hismo not enough?
I worked on a configuration importer. We can analyze many many versions now :-)
I implement a importer for Smalltalk.
For now, I can load histories for a package, for a metacello configuration, from a
repository.
Have a look at the Spirit project on ss3.gemstone.com/ss
It contains a lot of scripts to load versions of Mondrian, Versionner, Spy, ...
A first part is build in Pharo (building snapshots
from Monticello), and a second part in build with our java software and build the history
file. We can export xml, sql or swipl, which allows us to build prolog queries.
Here (http://code.google.com/p/harmony/wiki/VPraxis) is a tutorial for the java VPraxis.
For Smalltalk, I am working on it.
I generated the current Mondrian history in a swipl format, available here:
http://dl.dropbox.com/u/7739334/MondrianHistorySwipl.zip
An important point is that we do not into account the multiple branches (it is a current
work :) ). So, when there are multiple branches, for now, we check were is the merge and
we "ignore the multiple branches".
Now, for your question, we create a script:
http://dl.dropbox.com/u/7739334/mondrianScript.txt
Using swi-prolog (http://www.swi-prolog.org/) , you can call, in this script, the method
moreN(L, 10).
For the package Mondrian-Layout, it returns: L = [id_MOAbstractGraphLayout,
id_MOCircleLayout, id_MOSugiyamaLayout].
Which are the three classes that have changed more that 10 times.
For now, I am working on packaging all the things together.
But if you have some other requests, do not hesitate to ask me :)
Looks cool!

Having a reification in Moose of 100 versions of
Mondrian for example :-)
Just answering the question 'Which classes and methods of Mondrian have changed more
than 10 times since the day Mondrian was born?' cannot be easily done without a lot of
memory

https://www.iam.unibe.ch/mailman/listinfo/moose-dev I'm wondering: how big is a dataset >
500MB ? I've no idea how big it is.
Alex, what is your use case (in practice!) for more than 500MB?

It is problematic, and requires different memory
management than we
currently have.
I think if you need really big data sets, then use gemstone, which is
developed to deal with that specifically.
