what if MS is forced to publish all API's?
by Scott Bradford 09 Sep '01

09 Sep '01

with all the discussion going on in the press about what to do with Microsoft to remove their Monopoly power or at least see to it that they don't abuse their power, how to folks here feel about forcing them to release all their API's? I'm not a programmer myself, but it's my understanding that not having access to the API's is what makes wine such a challenge. If this is the case, would getting access to the MS API's allow Wine to be completed? I feel that a MS breakup wouldn't have done much to change things because they can still give information only to whom they choose, leaving MS to decide who can play and who can't. Having other ways to run the application base of windows software would remove the need to run windows itself, and in my mind, this is the easiest way to remove monopoly power of MS. What do you folks, the Wine developers, think should be done to MS?

Focus livelock
by Jukka Heinonen 09 Sep '01

09 Sep '01

I posted a patch that would fix a focus related livelock. However, I have to admit that the patch is quite hacky and likely not to be included in Wine. Since I would like to get this bug fixed, I thought to ask opinions about the correct way to fix the bug. The short description of the bug is that setting active/foreground/focus window in Wine calls X11DRV_SetFocus, which calls XSetInputFocus. This makes Wine receive FocusIn event, the handler of which calls SetForegroundWindow. Even though SetForegroundWindow does nothing if its parameter matches current foreground window, it can be easily seen that having more than one window can lead into livelock. This happens repeatably every time you start Colonization for Windows. I'm currently thinking about calling directly some WINPOS_* routine from X11 FocusIn handler instead of SetForegroundWindow. If the routine acted exactly like SetForegroundWindow except it made sure that it causes no calls to X11DRV_SetFocus, focus problem would be fixed. Unfortunately I have not figured any good way to pass an extra flag to default handler for WM_ACTIVATE, so that the routine would call something like SetFocus_DontCallDriver instead of regular SetFocus... -- Jukka Heinonen <http://www.iki.fi/jhei/>

This caused a division by zero in convert_modeline. Last time this happened, we considered this a bug in the X server, as under these circumstances, xvidtune also crashes. > Then will come the work of trying to reproduce the problem and see > how best to deal with this server (XFree86-SVGA 4.1.0 apparently). I don't think such a server exists. There's either XFree86 4.x with loadable driver modules, or there's XFree86-SVGA 3.x. The latter sounds more likely to have this kind of bug.

If I swicth back to latin everything's ok. It's a known problem, that Wine's x11 keyboard driver does not work with "non-sticky" switches. I have tested cyrillic input with XFree86 3.3.6, 4.0.3 and 4.1.0 with KDE and KiKbd, all works fine for me. Proper support for non-sticky modifiers, dead-keys and the real keyboard layout support requires almost complete keyboard driver rewrite. > BTW, why not to take layouts from X system itself? > Those wich are under /etc/X11/xkb/symbols Because XFree86 is not the only X11 implementation out there. -- Dmitry.

WM_[LR]BUTTON{DOWN,DBLCLK} in menus
by Bobby Bingham 08 Sep '01

08 Sep '01

I was writing a stupid app to help my friend learn to use menus in windows apps. It would call TrackPopupMenu on a WM_LBUTTONDOWN message. After some experimentation, I found that if I leftclicked in the client are, the menu would appear, as it should. But if, while the menu was still active, I leftclicked in the window's nonclient area (titlebar), the menu would appear elsewhere. By clicking the menu receives a WM_LBUTTONDOWN message, and determines that it should close the menu as it's not inside the menu, and it doesn't remove the message. This is normally fine, but if the click falls on the nonclient area of a window, the message should not be passed through. I believe this also applies to WM_LBUTTONDBLCLK, and the right button equivalents. Is there an easy way to determine what window the click would be passed through to, so we can check if it'll be in the client area or not?

Re: Bugs involving returning strings from API functions

It would be nice if all APIs that return strings behaved the same way, but unfortunately this is not the case: some count the terminating null, some don't, some copy partial strings when the buffer is too small, some don't copy anything, etc. We would need about as many helpers as there are API functions. Also be aware that the MSDN doc cannot be trusted at all on this matter, the correct behavior needs to be verified for each function. -- Alexandre Julliard julliard(a)winehq.com

The cast is wrong, we should do a copy there. CreateProcess takes a char*, not a const char*. Casting off the const and relying on CreateProcess to not modify the string is broken. Even better would be to convert the string to Unicode and call CreateProcessW; this would avoid a copy (well, right now it will cost an extra copy, but that's because CreateProcess should be fixed to do everything in Unicode). -- Alexandre Julliard julliard(a)winehq.com

Wine for OS X?
by Tyler Vano 07 Sep '01

07 Sep '01

Hi All, I'm new to this list (and to Wine itself) but was wondering, is there a project in the works to port Wine to Mac OS X (www.apple.com/macosx)? OS X *is* based on FreeBSD (albeit with a bunch of new fluff for compatibility & aqua), so a port shouldn't be that difficult. (650,000 lines of code and the guy says it 'shouldn't be difficult.') Personally, I think the eventually payoff would be well worth it. You'd get the entire community of ecstatic Mac users, drunk with the power of being able to run Windows apps directly on their Macs (without VPC.) Just like Linux/Unix, Apple's custom Mach3 kernel (aka Darwin) is Open Sourced. Just curious. - Tyler www.creysoft.com __________________________________________________ Do You Yahoo!?
