Almost forgot...
by Robert van Herk 18 May '04

This is the url of the website of the GP install people http://www.qsc.co.uk/source_ins.htm The idea is that you pay for another product (version controlling system) and then get the source code for GP install for free :-). Grtz, Robert

GP Install
by Robert van Herk 18 May '04

18 May '04

Hi people, GP-install is a free win32 setup builder. I have been using it in Wine, and it is quite usable except for some irritating (wine) bugs. For example, it forgets that it is installed and before each run needs to be installed again... :-( I read on the GP install website that they have source available, though at a price. Would it be wise if I would mail them and ask whether for Wine they would grant us (or me) free access to their source code, just to patch up Wine a bit? After all, it would also increase their possible install base... Greetings, Robert

RE: Getting the API's for Windows Applications

This would be a very rough estimation. Some APIs are simple to implement and some are not. The ones not yet in Wine are often of the second class but that is not a general rule. >By running wine-debug it is possible to get the API's used by an >application. I'm hoping that there is some simpler way (although I'm not >holding my breath) to read the API's used by an application directly >from the .exe or .dll. It really depends. You could walk the import table of the executable both the standard and delayed imports and get quite far. dumpbin or whatever it is called can do that. However this will not account for dynamically imported APIs some applications do, to work for instance around API differences between different Windows version. Or another reason might be that a certain API is optional and the app should keep running eventhough that API is not available on the target system. I think to catch those APIs as well only API profiling would help. But it may not be the main issue here as the dynamic runtime linking is most often done to prevent the application from not starting up when the underlyiing API is not present. Rolf Kalbermatter

Ivan, As far as I know, you did not submit also a patch to the default configuration file to add this DLL with 'native' as default (which is a good thing as all the people having a Windows box have this DLL - it could even be installed if someone manages to install DirectX under Wine).

Re: IAutocomplete(5) Add sizing grip

I'm not sure how the sizing grip should look exactly, but it would be very nice if you could use DrawFrameControl(hdc, &rc, DFC_SCROLL, DFCS_SCROLLSIZEGRIP); to draw it. I'm sure it will make it a lot easier to theme the code in the (near) future. -- Dimi.

Patch for ReadFile with NULL hEvent
by Scott W Gifford 17 May '04

17 May '04

According to MSDN, the hEvent member of an OVERLAPPED structure can be NULL: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/ba… OVERLAPPED ... Members ... hEvent Handle to an event set to the signaled state when the operation has been completed. The calling process must set this member either to zero or a valid event handle before calling any overlapped functions. A program I'm trying to run takes advantage of this, and as a result triggered a lot of these errors from Wine: err:file:GetOverlappedResult lpOverlapped->hEvent was null I wrote a patch that solves this, although it may not be the best solution. If when ReadFile is called overlapped->hEvent is NULL, the patch generates a new event with CreateEventA and sets the structure member to that event. To create a unique name, it uses the hex address of the overlapped structure along with a fairly long string, which is pretty likely to be unique. This works for the application I'm running. If this seems like a good enough solution, I can easily modify the other functions which initiate an overlapped read to do the same. ----ScottG.

StarCraft speed
by sysadmin 17 May '04

17 May '04

Чистый листI have Celeron333@417+MatroxG200, FC1, kernel 2.6.6 latest Wine and try to speedup StarCraft. IMHO, there is bug in mga video driver or something related that do not allow wine to switch video modes from 16 to 8 bit and Wine falldown to 16->8 emulation. I seen the same in some posts at wine-devel. Week ago I try StarCraft on Athlon 2500@3200+ATI Radeon8500, same FC1,Wine and amazing how small speed increase. Using oprofile I track that 99% CPU spend in dib.c in X11DRV_XXXX_8 (sorry don’t remember exactly). Using printf I investigate that 99% CPU used to convert internal wine 8bit with palette 640x480 picture to 16 bit format. There is some asm magic there, I try to speedup it ( lodsb/loop was be slowest instr. in IA86 at least at Pentiun Classic ) and replace by my 8X loop unroll code but nothing changes. The question is: Does anybody look at curent directx 2d code alg ? May be StarCraft engine use some “update region” and current Wine DirectX does not track clip list exactly, so Wine waste CPU converting big 640x480 but not small regions ? And what status of dga2 , why it cannot change color depth ? /dev/mem permissions is 777. I try StarCraft as root and in 8 bit desktop and it load main menu and completely block keyboard and mouse (btw, menu animation work really fast J) so I must press reset to reboot.
