It is under the modified BSD license, ie the BSD license without the advertisment clause, more often called the X11 license.

Umm. I feared that question would come. The "protection" the LGPL (or GPL) that Marcus proposed is IMHO largely an illusion when it comes to libraries. Sure we might use a strict interpretion as a weapon in a PR campaign against possible voilators but we don't have the resources to sue somebody and I very much doubt we would succed either. If I was I judge I wouldn't want to touch the issue of what constituted "linking" with a ten foot pole. Beside since where was no real damages since Wine was already free I would probably look for an excuse to dismiss the case as early as possible. No, a license change is not the answer to our problems. > My concern is not so much about Transgaming, I trust that Gav means to > do the right thing, Agreed and I think we should allow them considerable time to consider their position as well no need to rush something. > even if I don't entirely agree with his methods. Well, money makes the world go round whether you like it or not. :-) > But I'm worried that if Transgaming succeeds, it will set a precedent > that others will follow, who may have no desire at all to do the right > thing for Wine. Succeed with what? Now that Transgaming has done the hard work of getting InstallShield to work and even been kind enough provide the source code eventhough under a propritary license it can't be that difficult to look at it and provide an alternative implementation. Note that Gav said: < To say that our work is preventing anyone from doing a free version of DCOM is < completely incorrect. To the contrary: we have already contributed < substantial amounts of this code to the public tree - thousands of < lines, in fact. That can only help anyone with a sudden and unexpected < interest in recreating our work. We could quite easily make InstallShield work ourselves now that they have don't all the tedious debugging and we know what needs to be done. Note copyright only protects expression not fact or ideas (or hard work for that matter). In light of this it might be advantagous for Transgaming to release their InstallShield code. But as I said lets no rush things. I'm prepared to give them the benifit of the doubt and wait for them to decide. However my (and presumable others) patience in not boundless. > What will happen if 5 different dlls are improved and > released by 5 different companies under 5 different non-free licenses? When we had to decide which of the companies we trusted to release their code in the not so far away future and which we don't trust. The work of companies that we don't trust is ignored and we work on as we always have.

Improved redraw performance when application loaded
by Dave Hawkes 13 Dec '01

13 Dec '01

changelog: Reduced the time for a window with many child windows to be displayed. More info: A large application was taking up to 10 seconds to display its main window. This appears to be due to X individually exposing every child window (of which there are very many) of the main application window and then wine forcing a redraw on the parent of every child and then all the subchildren again (!) resulting in the accumulation of a huge redraw list. This patch will force a redraw only on the child and not the parent as X will eventually expose that anyway. After applying this patch the initial redraw dropped from around 10 seconds to about 2 seconds and I could not find any painting problems If anyone else is having slow application loading problems of this nature, then please try this patch.

Alexandre Julliard has changed a strangeness of BeginPaint : when the update region is null, Wine used to paint the whole window. New code set an empty painting rectangle. However, if the empty update region comes from an earlier Wine bug, the new code replaces excessive repainting with no repainting at all. I have already an app that shows this problem. As I was saying in reply to Andi Mohr, better code can reveal better old bugs... Gerard

This does not mean that the patch is wrong of course - maybe 2 bugs were compensating each other before. Gerard

Re: OSS fixes

Eric wrote: > could the people who had issues with the latest OSS patch(es) test > if this one fixes all their issues ? This patch causes both Riven and Myst to immediately freeze for me, and no sound at all. Without the patch, the sound in Myst works pretty good (occasional brief dropouts). In Riven without the patch, only the opening sequence has sound, and that has many large dropouts. I'm using ALSA drivers in Redhat. Duane
