In theory any library that the debugger uses will also fall under the GPL. And someone shipping Wine binaries may not be aware that parts of it need to be GPLed, and they will get flamed to death on Slashdot. I mostly agree with you that the FSF stance on dynamic linking has no basis in copyright law, but I'm not interested in providing the test case. So if you want to use readline you can patch your local copy, but I won't ship this in the main distribution. -- Alexandre Julliard julliard(a)winehq.com

As far as the source code to winedbg is concerned maybe but probably not. It might depend on whether --enable-readline or --disable-readline is the default, but that remains to be tested in court, but it is not certain it matters at all. The court might quite reasonably rule that no linking to readline has taken place yet and thus no derived work can have been created and even if they hold that some sort of linking has taken place it might not consider it a derived work. In short linking, especially potential linking, do not always imply a derived work which is all that matters as far as the law is concerned. Also note that I'm not convinced that any court will hold that the GPL is different from the LGPL in any relevant way with the possible exception of in bad faith trying to circumvent the requirements by trying to be "clever". Of course it is a little unclear that you really can do unlawful circumvention of license requirements. This is a like claiming that somebody circumvented trespassing your land by moving around it. Either you trespass or you do not. Either you violate the license or you do not. The analogy is quite good even in other areas: Even if you are on somebodies land you do not nessary trespass either because of copyright like "fair use" requirements in the law of most countries. As a sidenote: In Sweden "fair use" concerning trespass is so extensive that I never heard about _any_ case concerning it. > I think the benefit of using readline in the debugger is much too > small to justify the potential license issues this would cause. Only the debugger (winedbg) links with readline => only the debugger can be effected. Trying to claim, even though you didn't, that Winelib is effected is absurd since it is independent of the debugger. Distributing the debugger with WineLib is merly an aggregation nothing more.

Re: PATCH: Move 16-bit COMM stuff to USER, where it belongs

While the idea of the patch is correct, I think it would be much better to fix the huge code duplication while everything is in the same file. The 16-bit stuff should be implemented on top of the 32-bit stuff, instead of duplicating most of it. -- Alexandre Julliard julliard(a)winehq.com

But then the code can no longer be distributed under a non GPL compatible license, while this is allowed by the Wine license. I think the benefit of using readline in the debugger is much too small to justify the potential license issues this would cause. -- Alexandre Julliard julliard(a)winehq.com

Lost mail
by Alexandre Julliard June 18, 2001

June 18, 2001

Folks, I have been forced to change ISPs over the week-end, and it seems the old and new ISP couldn't agree on when to do the switch, so any mail sent to me during the week-end probably got forwarded to /dev/null. Also could people who submitted a patch to wine-patches please send me a private copy? I know they are on the mailing list archive, but it makes my life a lot easier to have everything in my mail box. Thanks. -- Alexandre Julliard julliard(a)winehq.com

set_file_pointer and 64 bit file access
by Bill Medland June 18, 2001

June 18, 2001

I see we are in the middle of converting set_file_pointer towards 64 bit file systems. Currently the code is confused as to when to change from unsigned to signed int for the low 32 bits. Should it happen in SetFilePointer before sending the request (which means we end up changing the request format) or should it happen within set_file_pointer (after changing the argument back to a signed int; this would also require work in SetFilePointer to get it to set up the request correctly). Any views? Bill

Not as long as it's optional (that patch even supported ./configure --without-readline, so no trouble, such people would just disable it).

No, it is enough that it is GPL compatible which the Wine license is. Whether we should is another matter though. Just linking it to the debugger is rather harmless IMHO though.

Dosvm not initialized for Direct port access

Hallo, some license manager dll (lmgr327a) manages to read IOPORT 0x40 from 32-bit code.
