The comment about sleeping lions is well taken, but I've worked with apple legal before, when they had their own building and were really mean (and overfed, happily :-)
I'd wait till all the heavies on this board weigh in for a concensus, but we do have a lawyer with some time he owes us and a lot of experience with our software and protecting it. I think he could probably do the job for us as a community, I'd volunteer him for the trenches if there is community interest, with the goal being absolute clarification (given legalese) of what's a hands off integration relationship with squeak, i.e. solid protection for plugin apps that do not have any squeak side modifications that aren't open sourced. In my own case, protect my plugin and let me keep my copyright on my unique grammar for communicating with my plugin, I'll even cough up _all_ my squeak side code, base platform or pure application.
If you're amenable or opposed to this idea, send me a note. I'll tabulate results for a few days and then repost them, and everybody can pitch in and bitch :-)
This is presupposing I'm not murdered on .dev for casting aspersions at iterator loop speeds.......
Regards
Mark

There have been rumbles on the squeak-dev list from time to time ;)
Could you set up a war plan to clean celeste?
I think so.
Celeste is also interesting because it has a lot of functionality that even non-Celeste users might want. For example, sometimes you want to compose and send an email message from Squeak, but *don't* want to be a full fledged Celeste user. (E.g., mailing changesets/bugs/etc. to the list). There are a variety of Celeste UIs, etc.
It would be good to extract celeste from the squeak image, do a call for tests and lead a refactoring efforts. This way we could: - have a better celeste - learn in the process
Yep. And gain a few things in the process. Celeste's persistence mechanism is a tad primative...but useful! If it can be made so that the *interface* is relatively stable, but the storage backend and filter/query process were registerable, well, that would rule :)
I think that Celeste is "well" separated from the core so this could be interesting to try.
Yes.
Cheers, Bijan Parsia.

OK, Cees seems to know whereof he speaks, he certainly calls our concerns out clearly, I'm off to read the GNU Library license again.
I'd be curious if anyone has already clarified it's application to the reverse situation, i.e. our VR engine is fundamentally a (great big fat badtempered) plugin library for Squeak. We have no problem giving away any changes we make to squeak or any non-VR code, we just want to protect our copyrights on our core library plugin. Anyone seen how the LGPL has been applied to this, say in creating 3rd party commercial libraries for gnu compilers.
Re the death of IP in general, Cees, I'd tend to agree, software patents show how low we are sinking. On the other hand, one needs to make a living. And in general, if you give it away and ask them to pay if it works, you starve.

I agree. If you look at changeSet #3746, ... ----------------- Introduces a new image partitioning tool that is essentially a local version of majorShrink. The idea is to pick some application like Scamper, or some cluster like all the 3D classes, and remove it, and also remove everything that is solely referred to by it. The way it works is: Record all unsent messages and unused classes at the outset Mark the application or cluster as removed Note all *newly* unreferenced methods and unused classes and iteratively remove them as well For example, the expression Smalltalk reportClassAndMethodRemovalsFor: #(Celeste Scamper MailMessage) reports 63 classes and 155 other messages that can be removed.
Also, introduces a new method, fileOutAndRemove:... that will take such results, build a changeSet from them, fileOut everything that is about to be removed, and then remove all of the classes and related messages as well. For the above example, this method produces a 290k fileOut, and saves about 104k from the system. More importantly, if you fileIn the changeSet afterward, the system returns to approximately its former size, and you can run Scamper again. It's a way to fileOut a package that never existed. -------------------
So a year ago, that group and that method (for which there is now equivalent code in modules) worked perfectly as a module a year ago.

That centers around "If the Modified Software contains modifications, overwrites, replacements, deletions, additions, or ports to new platforms of: (1) [class lib], or (2) any part of the virtual machine, then [you have to share the source].
I would not call a plugin library an addition to the virtual machine - the VM is for me the SLANG stuff plus the platform glue, and I think that that's what is meant in the license.
I *think* that Apple did not mean to call a plugin library an addition to the virtual machine. However, a bad-tempered lawyer at Apple *could* construe your plugin library to be an addition to the virtual machine. Given the track record of big companies' legal teams smelling profit, blood, or just fun, I'd get a statement from Apple "we don't consider the vibrant 3D plugin as a blahblahblah"...

At the time the license was written, there was no such concept as a Squeak VM plugin. However, one of my major motivations for doing the VM plugins was in particular to be able to "access" proprietary code. In other words, a plugin is nothing but an optimized FFI interface (it really is). That's my way of thinking about it and I don't believe that anyone would consider some function called through FFI being an "addition to" the virtual machine.
I *think* that Apple did not mean to call a plugin library an addition to the virtual machine. However, a bad-tempered lawyer at Apple *could* construe your plugin library to be an addition to the virtual machine.
That reminds of a recent conversation with a lawyer. Asking "okay, so how can make this issue airtight" the response was "Heck, you are talking about law here! There is no such thing as 'airtight' in law. Companies can sue you and they _will_ sue you no matter what you do."
Given the track record of big companies' legal teams smelling profit, blood, or just fun, I'd get a statement from Apple "we don't consider the vibrant 3D plugin as a blahblahblah"...
Actually, having a number of companies ask for their permission might just raise their interest. Don't wake sleeping lions...

Hi Stef -
I've been reflecting more on this since responding to your message. I completely defer to you and Henrik on which way to go, but I see a choice here:
Either we... Find various small things that are pretty modular and do them first
Or we... Take various big chunks that are pretty modular and do them first.
By "big chunks", I'm thinking along the lines of the various discardX methods in SystemdDictionary (like all of 3D, all of networking, etc). So this would mean instead of doing Celeste, we do all of Networking as a chunk. Then *later* we refine this and break networking down into Celeste, Scamper, IRC, HTML, PWS, etc.
I just have the feeling that it might not be much harder to draw isolation lines around the big chunks than it is around the little ones, and the payoff might be higher, in that it might *soon* be possible for mere mortals to perform their own versions of majorShrink, and have it really work.
As I say, I'm happy to go with whatever you guys decide, but I did want to call attention to the choice, and have you make a conscious decision.

Dan,
Personally, I'm in for some of the larger chunks first. Why? Well, for one thing it's going to test out the framework in some areas that'll really benefit all of us. Secondly, it's perhaps not as easy to define the boundaries for an application like Celeste (some people have already pointed out that some of the stuff Celeste is doing might be of interest for other apps so a careful definition of boundaries is important). Thirdly, having fast and "big" results (like the ability to cut out and load stuff like Wonderland and 3D) will convince people that we're _seriously_ talking about modularity and encourage them to build their own designs into their frameworks.
Just my =80.02, - Andreas

Maybe it'd be an idea if SqC would ask Apple for a clarification here. I think it is a very important issue that we can make clear (in terms that a lawyer will accept) what is and what isn't allowed in the area of proprietary extensions - if you want to make a product a success, you need to be prepared for companies wanting to earn money with it. The plugin bit seems to be a big hole in the license...
(or maybe it would be enough to strike the term 'plugin' and call it 'fastFFI' ;-))
You may be right with your remark about now waking sleeping lawyers. I may be right with my remark about better being safe than sorry. WANL (we are not lawyers). IMHO, the fact that this arouses questions that I feel we cannot answer is a bug that should be fixed.
