[RFC] Better OpenGL separation
by Lionel Ulmer 11 Nov '02

11 Nov '02

Hi all, The current OpenGL code (well, to be more precise, the current WGL code) is really X11 dependant and is only separated through hacks via ExtEscape mechanisms to get X11 specific variables. As I never was able to find documentation about the OpenGL ICD mechanism (ie the way all this is handled in real Windows), I see three possible solutions : 1) As almost all WGL functions have an HDC or OpenGL context argument (for those having a context argument, the corresponding HDC can easily be found). Thus one solution would be to use 'DC_GetDCPtr' to get the DC pointer and then move all these functions in the GDI function pointer table. The problem with that is that 'DC_GetDCPtr' is already flagged as a hack and so I am bit reluctant to use it :-) 2) Put all HDC function in GDI itself and replace in OpenGL's spec file all of these by forwards to GDI. 3) Use the ExtEscape mechanism to not only get specific variables, but something akin to what DDraw does to get the HAL function pointer table and then use these pointers to do the real low level work in the WGL functions. For the moment, I think 3) is the best. Feel free to propose other solutions :-) Lionel -- Lionel Ulmer - http://www.bbrox.org/

[RFC] The new Wine FAQ
by Dimitrie O. Paun 11 Nov '02

11 Nov '02

Folks, As promised, the new Wine FAQ (in beautiful color, and an amazing bouquet), is ready for public review before the end of the week. So there. :) At the moment, it is available for your viewing pleasure here: http://www.dssd.ca/Wine-FAQ.html Keith Matthews, and Thomas Wickline did most of the work on this one; we owe it to them. We've also received a number of useful comments from Jeremy White, thanks Jer! Please direct all comments, suggestion, and (last, but not least) flames, to the brand new wine-faq(a)winehq.org. All are most appreciated. Hopefully we'll have this one on the site not before long. -- Dimi.

Page faults
by Duane Clark 11 Nov '02

11 Nov '02

Having just added more memory to prevent the disk swapping I was encountering, I now seem to be crashing with a page fault. I don't really know enough about how the memory is handled. Is this likely to be a wine bug? I am running native versions of msvcrt and mfc42, but pretty much builtin for everything else. This is running Xilinx fpga_editor. When running on this particular design, it appears to use about 350MB of RAM. Unhandled exception: page fault on write access to 0x9c5a7c4c in 32-bit code (0x7800d77a). 0x7800d77a (MSVCRT.DLL._set_sbh_threshold+0x6de in C:\WINDOWS\SYSTEM\MSVCRT.DLL): movl %ecx,0xfffffffc(%ecx,%edx,1) Wine-dbg>bt Backtrace: =>0 0x7800d77a (MSVCRT.DLL._set_sbh_threshold+0x6de in C:\WINDOWS\SYSTEM\MSVCRT.DLL) (ebp=4048f768) 1 0x7800ccf7 (MSVCRT.DLL.??_V@YAXPAX@Z+0xe4 in C:\WINDOWS\SYSTEM\MSVCRT.DLL) (ebp=4048f7a0) 2 0x78001026 (MSVCRT.DLL..text+0x26 in C:\WINDOWS\SYSTEM\MSVCRT.DLL) (ebp=405a2dcc) 3 0x5f40b4fe (MFC42.DLL.1576+0x52 in C:\WINDOWS\SYSTEM\MFC42.DLL) (ebp=405a2e8c) 4 0x400c53fc (start_process+0x258 [process.c:564] in libntdll.dll.so) (ebp=405a2f38)

Re: PATCH: cups dynamical dependency

IMO we should just include a copy of the CUPS headers that we need, and drop the compile time check altogether. In fact, this check is misleading, as it suggests that we've verified some sort of compatibility with CUPS which we haven't. We _assume_ that a certain API is available at runtime, so why pretend we use something that's on the machine we compile on? -- Dimi.

Re: Wine 0.8: VB compatibility !!
by Ann and Jason Edmeades 11 Nov '02

11 Nov '02

I have a VB prog (see www.badcomp.co.uk) which I spent a long time getting working under Wine and fixed all the oleaut32 Var* routines it used. However if you look at that dll, there are still a huge number of stubs. Additionally the date/time handling is (was, anyway) pretty useless. I would strongly recommend if anyone starts writing VB testcases they try and exercise the Variant cases as well as the standard types (...and no, I dont have time!) VB Window Icons dont work in the wine tree - Marcus sent me a fix for OleLoadPictureEx which solves the problem but he never submitted it to the wine tree (I have a copy, but not of the license it was under). Also, Icons containing transparency dont work for me either, but thats not a vb thing, I guess. I never got printing working (wine and cups doesnt seem to handle hplj's very well - I've seen a lot of problem reports about that) but aside from that, the functionality worked fine as far as I could test. If I ever get motivated I'll try to test the printing as there is a huge amount of code I wrote to do a print preview, and that will probably highlight more var fn's missing. Regards, Jason

I think you need more than one than one buffer perhaps. One per > file of course. Havent looked that close... I'll make a version with more, but smaller buffers. I found one bug also; on certain case, a closed file's buffer might has been used for the next opened file with same HANDLE. Where is CLOSEFILE code?! Shouldn't it be on file.c? I need to find it to invalidate the buffer at correct place! I think that the original problem is that wine opens and closes unix file for every ReadFile. This will propably flush all linux own buffers and linux filesystem has to read the same data over and over again (when application calls ReadFile with small buffers, of course). Opened unix files should be kept open as long as corresponding WINAPI files are open. BTW. I'm using totally non-MS system. Is there any problem with MS dll's? Hannu ps.

Just so everyone knows, since I have Outlook (and Evolution) support with my ISP's email now, I have switched over to it for my list needs. Any emails to me should be directed here, I have updated my accounts with the winehq server. I will still accept emails over at yahoo if need be but the majority should go here... -Dustin
