This patch fixes > the WINE debugger to handle this exception, just like MS VC6 debugger does. something seems wrong in your patch... the szName field from the exception field is never copied from the debugged program space to the debugger space (only the address is) so, you should use ReadProcessMemory instead (something like ReadProcessMemory(pThread->name, sizeof(pThread->name), DEBUG_CurrThread->process->handle, pThreadName->szName); ) also, I don't like the fact that you put the #define in a public header file and the exception struct definition inside the file it would make more sense to me if both were either public or private (I'd go for private, since those values don't seem to be defined in Windows' standard headers) A+ -- --------------- Eric Pouech (http://perso.wanadoo.fr/eric.pouech/) "The future will be better tomorrow", Vice President Dan Quayle

for personal reasons, I will no longer be able to write the WWN (and I haven't in the last couple of weeks) so, if someone wishes to take the job over, I'd be happy to help him (her) to set it up A+ -- --------------- Eric Pouech (http://perso.wanadoo.fr/eric.pouech/) "The future will be better tomorrow", Vice President Dan Quayle

What I wanted is something short and simple, so I could help people on the news group. The use of my patch could be explained in *one* line and it would have worked with Wine right 'out of the box' :-)... something the internal debugger does not do anymore since a long time. I am afraid that this thing will be more complex to setup and to use that the debugger - something already too complex for many people. And well, I almost never use the debugger myself because it crashes at the slightest provocation so I don't feel much about saying people to use it. So in short, after all my 'needs' (helping ppl on the news group) are indeed specific :-) Gerard

Those messages/fixme's help a lot to add missing page and bin type into psdrv: they are not complete now. And without message about missing fonts in ppd/afm it would be nightmare to track down problems with ps fonts at least for me.

Newbie question...
by Elan Feingold April 4, 2001

Hi, I have a 3rd party x86 DLL file, that I would like to use under Linux. I have read the documentation on the specmaker tool, which would seem to provide some help. The thing that makes my case a bit different is that I would like to use the DLL within a Linux native program, not a WineLib program (its just a command line application and I need it to be very lightweight). Im pretty sure the Wine code can help me out, but Im not sure what the easiest way to proceed is, and what parts I need to use. Thanks in advance, -elan

T@x2001: Linuxport via Wine
by Joerg Mayer April 3, 2001

April 3, 2001

Just found the following at the SuSE portal pages (German only): http://portal.suse.de/de/content/reports/tax2001.html Rough translation on the introductory paragraph: The program t(a)x by Buhl Data has been around for the Windows platform for some years. This year, the current version T(a)x2001 has been made available for the Linux OS for a first time. In order to do this the Windows emulator Wine was used. Wine allows using Windows applications running Linux. This emulator has been modified to work with t(a)x2001. The summary as far as Wine is concerned: The program should be more stable and faster. Does anyone know which modifications were made to wine? Ciao Jörg -- Joerg Mayer <jmayer(a)loplof.de> I found out that "pro" means "instead of" (as in proconsul). Now I know what proactive means.

Yes, in the Wine debugger, which should store the name and simply continue execution, just like the MSVC debugger does. -- Alexandre Julliard julliard(a)winehq.com

Re: Speeding up wineserver syncronization objects with shared memory
by David Howells April 3, 2001

April 3, 2001

Okay, I've thought about how to make the wine kernel module easier to use for Wine, and I've started adding another API to it - one that interprets Wine server messages. When I designed the module initially, I decided to make it possible to add as many API's as I liked, so in theory it's not too difficult. I'm currently performing a major rearrangement of the files that comprise the module: * Splitting the current win32 API bits out of the same files that contain the actual object class implementations. * Putting the core and the API's in separate subdirectories. * Abstracting name support, so that the internal API takes an "object name" which the user API is responsible for extracting from userspace and converting from WCS/MBS as necessary. * Fixing introduced bugs. This does not mean that I'm getting rid of the Win32 API I've already got! It will just be optional. Calling the new API will be by means of either: union generic_request msg; syscall(__NR_win32,WINESERVER_WINE_SERVER_MESSAGE,&msg); Or: union generic_request msg; int fd = open("/proc/wineserver"); struct WineserverIoctl wioc = { WINESERVER_WINE_SERVER_MESSAGE, &msg }; ioctl(fd,WINESERVER_IOCTL,&wioc); David

Interesting Magic # exception understood by the MS debugger...
by James Hatheway April 2, 2001

April 2, 2001

Hi guys, I encountered something interesting while debugging a newer build of my application. I noticed that all of a sudden I was receiving approximately 10 new exceptions in the debugger on startup that I wasn't receiving before. After digging a little, I found out that the app coders were making use of a 'hidden' feature of MS VC that allowed you to name your threads (thus allowing for easier debugging). To do this, you call RaiseException with the code of 0x406D1388. (Search on deja.com or google.com for "0x406D1388" for details.) The windows debugger seems to be on the lookout for this code. Of course, what it does in wine is just breaking into the debugger many times and getting on my nerves. :-) For now, I put the little hack I attached to this mail in my tree to save my sanity. My question to the list is, (A) is there a way to name threads in Linux/Unix (I don't think so, but of course I could be wrong) and (B) should we support MS's hack somehow in the official tree? -James -- James Hatheway Software Designer - Macadamian Technologies, Inc. james(a)macadamian.com ~ http://www.macadamian.com "Man könnte froh sein, wenn die Luft so rein wäre wie das Bier" "One could be happy if the air were as pure as the beer"
