Hello,
First of all, thank you for all the people who spend great deal of time on fixing our server. I've been watching the IRC log (http://tunes.org/~nef/logs/squeak/) and was admiring the work!
As mentioned in the leadership discussion minutes from Craig, the plan now is as follows:
- Make Squeak version 4.0. This is based on the 3.11 effort but get rid of or rewrite code that are not relicensed and make a fully relicensed version relatively conservatively. Etoys 4.0 is now fully relicensed, and we can bring the removal and rewrite changesets from that stream.
- Craig continue to work on the Spoon based system. It is dubbed Squeak 5.0. (My personal opinion is that because it is fairly different, it could have a different name, but...)
BTW, during the Etoys' relicensing effort, I made a little web app that lets you view *all history* from Squeak V1 to the latest version:
http://tinlizzie.org:8080/seaside/examples/authorship2
I can make a similar page for 3.10 or such, and also give a tool to check the unlicened code in a particular code base.
Ken and Mathew, how does it sound?

Keith would be the interested person, not Ken.
It sounds like a good plan. Do you have a patch I could use to get started? I would definitely like to see just how bad the situation is in 3.9 or 3.10. Croquet would be nice too, but I think the history of Croquet is much more muddled than the history of squeak.org

Ah, sorry.

Here is an announcement I made while ago:
http://lists.squeakfoundation.org/pipermail/squeak-dev/2008-September/131586...
This is based on a bit old database, but you can get the feel of it. Attached is the latest version of my Authorship2 code: you should be able to file it in and see the current status.
Croquet would be nice too,
Nice in terms of what?
but I think the history of Croquet is much more muddled than the history of squeak.org
Well, what makes you think so? The set of developers of the Croquet image is definitely more limited, and the "team" generally had better control on the image than the main stream.

I forgot to mention one thing. The updates are at:
http://tinlizzie.org/updates/etoys/updates/
. Take a loot at
http://tinlizzie.org/updates/etoys/updates/updates.list
and fetch the updates for "etoys3.2".

Probably not. Remember that both Tweak and Croquet were MIT licensed from day one which really simplifies matters since all contributions were always understood to be MIT licensed. The only question is whether the Croqut base image (deployment/Homebase.image) is squeaky license clean or not (pun intended). A quick check - comparing the versions in homebase.image with the versions in etoys4 - shows that any auditing effort should be *very* manageable (mostly because they share the same 3.8 ancestry). Here is the total of methods that are in Homebase.image and where etoys4.image has different versions (scripts below):

Note that for most of the core packages (like Network or Morphic) I would expect the changes to come from the etoys image due to the modifications done for OLPC. In reality I would expect that you would probably have to audit less than 5% of the code base. And of that I would expect a goodly chunk to be written by yours truly which means it is either covered by the VPRI or the Croquet license.
Cheers, - Andreas
