It seems clear that we should do away for the most part with having applications interface directly with sound drivers like oss/alsa, and instead go through sound servers like arts/jack/etc. In technical aspects a callback based architecture is far superior to a polling based architecture. It has a lower latency and enforces a cleaner sound implementation on applications. What I haven't seen yet is a widely used audio server that people agree upon. Someone really needs to take the lead and start pushing a callback based sound server that is under active development(arts appears not to be) that is not kde/gnome specific.</rant> > what I really fear is the real maintenance of those drivers > as of today, OSS is maintained, I cannot really tell the same for the > others > it's never a bad idea to share code, but I fear we're not going to be > able to maintain all the drivers (but we don't maintain them all today > anyway) > so go for it > (sorry for thinking while writing ;-) Wonder when we can phase out the OSS driver and concentrate on the ALSA one. Seems like a waste to support two drivers that fulfill the same role. Chris

jack audio driver
by Chris Morgan Oct. 8, 2002

Oct. 8, 2002

I have an audio driver for the jack audio server, http://jackit.sourceforge.net. This is a callback based server, so each time the server needs audio data it executes a client callback function. I was wondering if there was any interest in having this driver as part of mainline wine code as an example of how to write a wine audio driver for a callback based architecture. Chris

automagical .sym symbol loading in winedbg?
by Greg Turner Oct. 8, 2002

Oct. 8, 2002

Is there any way to get winedbg to automagically load .sym files from some particular directory? winedbg> "symbolfile [full unix path of .sym file]/[filename.sym]" it seems to work; but what a hassle! All that crap is in "/var/src/nosrc/DOTwine/fake_windows/windows/Symbols," quite a lot to type over and over (yes, I have cut-and-paste capabilities... but it still sucks). I see it looking for ".dbg" files but not ".sym". I'm experimenting with the Windows 98/98SE DDK symbol files, installed into my fake_windows. I also noticed _NT_SYMBOL_PATH references floating around in there, but that's for ".pdb" files, and unlikely to help, right? Anyways, I tried it, it doesn't help. :( -- gmt "If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace.

A very similar approach to what I was working on and it looks like the right thing to do. I haven't had time to test it yes but if you have it should be ok to go in. I'll mail another patch or two to fix other issues relating to environment passing soon.

Re: Re: another MZ_Exec() problem...
by chrismorgan＠rcn.com Oct. 8, 2002

Anyone planning on looking into this in the near term? It could be fixed relatively easily in MZ_Exec() if I knew of some way to get the environment variables and their values. I'm not sure if the same kind of fix would apply to fixing CreateProcess().

I've set the lpEnvironment parameter of CreateProcessA() to null to have it inherit the environment of the caller but this isn't working correctly. The path and other environment variables aren't being inherited. Ideas on how to either get CreateProcessA() to inherit properly or where I can find the environment settings? I noticed the env_ptr in the parmeter block but I'm unsure if this is what I'm looking for or where to find more information about it. > moreover, explicit env heritage (ie passed in CreateProcess) is currently bugged > A+ > > >

W(w)indows messages
by Fabian Cenedese Oct. 8, 2002

Oct. 8, 2002

Hi all I still try to solve the problems I have in window handling. There is a function X11_ShowWindow. First comes a big switch/case of all show commands. Then is the call to SetWindowPos with the new coords. But this newPos is only filled in few cases. So most of the times I end up with a SetWindowPos with coords 0. But still it somehow seems to work so I continued my search. In SetWindowPos is a call to WIN_SetRectangles with newWindowRect and newClientRect as parameters. But in the end is a message generated WM_WINDOWPOSCHANGED where the old winpos with the 0s inside is given as argument. Shouldn't that be also one of the new rects resp. shouldn't these new coords be set in newpos? I tried it but wine broke off with a stack overflow as I somehow generated a recursive calling. I have a call to ShowWindow in my OnWindowPosChanged handler. This works fine in Windows but wine seems to generate a new message WindowPosChanged what Windows doesn't. The use of ShowWindow in OnWindowPosChanged is maybe questionable but nonetheless it shows that there is something different in wine. Deleting this call to ShowWindow makes it run ok. But I noticed also previously that wine seems to generate more messages than Windows does. The main reason why I started this exploration is that some of my docked windows didn't show up. Then I found that I always get coords of 0 in my OnWindowPosChanged. So we come back to the above mentioned newPos. I'm quite new to wine and especially this window handling stuff, but this seems to be the biggest problem to make my app work with wine so I'd really appreciate some hints. If someone knows a book about Windows Messages I'm game. Thanks for reading :) bye Fabi

Languages/Locales
by steve.lustbader＠philips.com Oct. 8, 2002

ChangeLog (memory/codepage.c): Implement GetUserDefaultUILanguage Implement GetSystemDefaultUILanguage I implemented these functions in codepage.c since similar functions (GetDefaultLangID and GetDefaultLCID) were already there. Why are these functions in this file, instead of in dlls/kernel/locale.c? It seems locales and languages aren't really implemented yet (just hardcoded to English) - is this going in for 1.0 or is it not planned for the immediate future? -Steve (See attached file: patch.diff)

One thing I noticed is that File Open/Save As dialogs in any app now show only icons (the filenames are all blank).
