Yes, but in the mean time it is likely that we scare away potential good companies and regardless of the LGPL be effected negativly by bad companies using the lopeholes in the LGPL. > On the other hand, if society moves towards 1., then the LGPL is the > perfect tool because it turns the stronger copyright law > against itself. > In this case, it is the only moral/ethical thing to do: to > turn an evil > instrument against itself, thus provides the > _negative_feedback_loop_ that > is missing at the moment. > > Moreover, if you are worried about the fact that open source > software is > so influential that it can influence the debate over the doctrine of > derived work, then even more so should we opt for the LGPL > because in that > case we would contribute to a negative feedback that will deter > politicians from making the copyright law arbitrarily stronger. So you want Wine to be the catastrofic failure, that was used to change copyright law. You can't seriously want this.

DirectX and DCOM fall in this cathegory. I have use the Crypto API as an example several times that to illustrate that the DLL:s isn't a relevant protection boundary for the LGPL, even Alexandre seems to accept this. In any case if the DLL is mostly implemented there is very little reason for a company to try to enter the market, it is simply to dangerous, so I don't see the problem. > > > I fail to see _any_ moral/ethical/philosophical problem with > > > this.

I leave them to for example Gavriels that IMHO has done a good good job at that. I have been trying to approach the problem from the other side, that the LGPL doesn't provide much protection at all.

Your analogy is flawed, Wine is not living in the meaning that it, if it is to unselfish can die.

Yes, and the key is minor ways and I believe that is a absolute non-issue as I have explained before. There is no profit in holding minor improvements. > > > 2.

That is, there's no other case. QED. OK, since you bring mathematics in to it, I will try to explain in mathematical terms: "The set of people is not invariant over a license change." In fact the set of people are likely to be considerly less. While I have no strict mathematical proof of that, I especially point to Gavriels' reply concerning Corel and Transgaming.

However, I think that if you move to Europe, especially northern Europe you will find that people have different opinions. While most people there certainly do not believe in Communism and to various degrees understand why is doesn't work, people are more inclined to be believe in this principle. Actually I think the reason for this is more Protestant Christianity than Communism, but why is not really that important. > And to get > off topic, why is that?

And if they borrow some obscure functions, they might even supply some bugfixes in hope that at a later stage there will be more bugfixes waiting for them when they borrow again (resync) a year later. And if they don't, who has been hurt? If Wine was LGPL:ed they certainly wouldn't have borrowed at all, so no chance at all of getting any bugfixes back at all. > I recall Uwe's usual .sig which is: > Free Software: if you contribute nothing, expect nothing.

I don't think that one came out the way you hoped. Try again.

Installshield 6 (inter-proc) patches
by J.Brown (Ender/Amigo) 19 Dec '01

Any idea when Oves interprocess patches will be put into the main Wine CVS tree? The code currently in WineX isn't really that ugly at all, and it is a very important part of Wine to have working IS6 support.

The main problem is that using the LGPL introduces uncertainty to what is allowed and that advantages is not good enough IMHO to outweight the disadvantages. > Patrik, your entire arguments are based on such obscure > assumptions that's > scary!

Nothing else. Even if their understand of other parts of law are perfect it matters not. IIRC their arguments always seen to assume that the doctrine of derived works is unproblematic if applied to source code. > It's the best we can hope for now.

To connect again to the example of the spirit of Communism: I am sure it was very popular to dismiss to fear of the opponents by saying what you have been saying. Trivialising the problems and clinging to clean, pure and uncomplicated spirit of it.

The main point is that what is legal allow is very unclear. I'm not primarily trying to explain what is legal allowed or not, just pointing out some difficulities in understand what the law really means. > Stop for a movement and tell me: are you against the letter > or the spirit > of the LGPL. Asking that question is like asking whether I support the spirit of Communism: "From each according to his abilities - to each according to his needs." Well, it sound nice doesn't it? However doing a little deeper analysis I realize that the price for being able to do this is not worth paying. Note however that I'm not equating GPL or LGPL with Communism. It was just an example from real life, that you get more that you wish for. See below. > The spirit is simple: > > Here is this thing, we give it to you for free, use it for your own > benefit however you see fit.

I'm against the fact that the GPL or to a smaller extent LGPL tries use the doctrine of derived work as a weapon to achieve their goals. It is a very dangerous weapon, since if the courts or the policitians decide that a strong doctrine of derived work is good it might be disasterous for society as a whole. Various commerical intrest might (read: will) for example try to use this to stop 3rd party additions to their works and I don't want that to happend.

I don't think small improvements is a problem anyway and beginning an implementation of say DCOM is probaly not a small improvement and DirectX certainly isn't. > I fail to see _any_ moral/ethical/philosophical problem with > this. Do you? Perhaps you have been more enlightend now.

No, I think you misunderstand. I'm not in the BSD camp as you define it. I do not nessarily believe that everybody will follow what the LGPL wants or at least that they will do things that they are certain would have been allowed if it was LGPL. And that is an important part of my objection: It makes it less clear what is allowed. > Before I go any further, I would like to stress a very important > point: Wine is in fact a collection of independent projects. > These are the > DLLs, and they nicely (and unequivocally) partition Wine into lovely > little, independent components. And this means that the LGPL is > independently contained to each and every DLL. It is the _perfect_ > position to be LGPLed. You forget that some "independent"(*) parts like the Crypto API are parts of other DLL:s (like ADVAPI32.DLL) for no particular reason. Actually large parts of the Windows API are "independent"(*). They are just helper function wrappers around other functions. (*) By "independent" mean that they just use other parts of the Windows API like normal applications do and claiming derived work for this would be absurd, just like claiming it for normal applications would be absurd. > At this point, I would like to know if people agree up to > this point.

Claiming that it is better for Wine as a whole is one thing, but claiming that limiting commercial intrests choices is good even for them, requires a explaination.

implementation of ImageList_*Drag*
by Michael Stefaniuc 18 Dec '01

18 Dec '01

Hello, the attached patch (it's my first wine gui patch, that's why wine-devel is CC'ed) implements the dragging part of the ImageList functions. It works quite well with FreeSolitaire besides the dragged image isn't drawn semitransparent. But how do I draw a semitransparent image? IMO this isn't possible with the BitBlt functions. The ImageList_*Drag* functions shouldn't produce flickering as per the MSDN documentation, but ImageList_SetDragCursorImage (at least in Win9x) produces a short flickering when called. I implemented this function to match the behavior of the native comctl32.dll, but it would be very easy to stop the flickering. Should I change it or keep the Win9x behaviour? bye michael Changelog: Michael Stefaniuc <mstefani(a)redhat.com> fixed/implemented the ImageList_*Drag* functions -- Michael Stefaniuc Tel.: +49-711-96437-199 System Administration Fax.: +49-711-96437-111 Red Hat GmbH Email: mstefani(a)redhat.de Hauptstaetterstr. 58 http://www.redhat.de/ D-70178 Stuttgart

I'm just off home now so I haven't time to learn sourceforge and download 100M. I need a share.h to go into the msvcrt (for two lousy symbols). I see that much of the msvcrt is based on mingw. Does it include share.h? TIA Bill
