Hi, what's the status of DIB engine (or where can one read about it)? Are the up-to-date sources still available? What kind of help would be needed?

In fact the texUnitMap entries are never set to any value < 0 other than -1, so it doesn't make much difference, but for the sake of consistency we should check for -1 here as well

Re: ntdll: detach modules based on inter-module dependencies (try 2)

My suspicion is that this bug should be fixed in winmm, but either way you'll need to show some test cases. -- Alexandre Julliard julliard(a)winehq.org

interesting. Do you have a list of contributors and their signoff on this license change? Or is it just you two? On Nov 24, 2007 12:36 PM, Alexander Nicolaysen Sørnes <alex(a)thehandofagony.com> wrote: > Change licence to AGPL > > > > Alexander N. Sørnes > > > >

wine 0.9.5 IO completion port questions
by Marius Slyzius 03 Dec '07

03 Dec '07

Hello all. I am trying to run ScimoreDB database which uses fibers, non-blocked IO for sockets and files, and completion port. It did started ok under 0.9.5 and seems it is working!!!:), so I would like to verify few things about async IO with completion ports before recompiling it with winelib. 1) will write/read file/socket with completion port is true asynchronous operation. I am asking because every time write/read operation returns true, and never IO pending error. 2) possible bug: the server sends 1500 bytes with WsaSend ( with 2 WSABUFFER ) and the client receive only 1452 bytes and calls WsaRecv again. Also on the server, the completion port receive event that transferred 1452 bytes. However, the last 8 bytes are never sends nor completion port event arrives. Is it perhaps something to do with the VMWare tool where I run Ubuntu 7.10? Please, send me an info also to my mail: marius(a)scimore.com , because I might miss the answer here. Thank you!

Hey Louis, Focht is using a pseudonym, and I believe it's Wine policy to not accept patches without real names. His patches should be used as guides only, and should not be reposted to wine-patches, until such time as he decloaks. If he doesn't want to decloak, I think we can't use his patches. I rather wish he would avoid attach patches to bugs, as it tempts people into submitting them as you have done, which is a waste of effort given Wine's policy. But I greatly value his ability to describe where and how Wine is wrong. - Dan

handle unimplemented function stubs
by nessi＠nessi-online.de 03 Dec '07

Hello all, I'm a Windows software developer and I'm trying to execute an application under the wine environment. Now I have a problem introduced with wine 0.9.49. I use the function RegOverridePredefKey from the advapi32.dll. To be compatible with older windows versions, I use the following code: LONG WINAPI (*RegOverridePredefKey)(HKEY hKey, HKEY hNewHKey); HMODULE hMod=GetModuleHandle("Advapi32"); if (hMod) (FARPROC)RegOverridePredefKey=GetProcAddress(hMod,"RegOverridePredefKey"); if (RegOverridePredefKey) RegOverridePredefKey(HKEY_CLASSES_ROOT, hKey); In wine 0.9.49 a stub entry for this function was created, but the implementation is missing. The result is, that the GetProcAddress function is successful, but the RegOverridePredefKey call fails. I can catch the EXCEPTION_WINE_STUB exception (see code below), but the application will nevertheless closed. if (RegOverridePredefKey) { long err = ERROR_CALL_NOT_IMPLEMENTED; try { // test for C-based structured exceptions err=RegOverridePredefKey(HKEY_CLASSES_ROOT, hKey); } #define EXCEPTION_WINE_STUB 0x80000100 __except(GetExceptionCode()==EXCEPTION_WINE_STUB ? EXCEPTION_EXECUTE_HANDLER : EXCEPTION_CONTINUE_SEARCH) { RegOverridePredefKey=NULL; } } What can I do ? I know, that I can find a workaround for this case, but this in not my problem. How can I handle, in principle, such exceptions? What is the reason for creating a function stub without an implementation ??? Thanks Nessi

kernel32:add ReadFileScatter
by luis.busquets＠ilidium.com 03 Dec '07

03 Dec '07

Just to add more clarity to the IPR of computer programs and if it is legal to decompile and implement a program again. In Europe, software is protected by Council Directive 91/250/EEC of 14 May 1991 on the legal protection of computer programs (http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=CELEX:31991L0250:EN:H…) There are a number of things that a software vendor cannot forbid. In particular article 6 speaks about decompilation. It can be done only if the information necessary to achieve interoperability has not previously been readily available (a.1.b) to achieve programs interoperable with the first one (a.1) but not to be used for the development, production or marketing of a computer program substantially similar in its expression (a. 6.2.c). It could be argued that wine is not replicating Windows as it is just the top API. Nevertherless, to avoid any legal problems, it is better to refrain from adding any patches obtained by decompilation.
