Help wanted: Implementing Wine dlls that need access to X11 commands.
by Robert North 16 Jan '03

16 Jan '03

I'm about to start serious implementation on the wintab32 dll. I now need some guidance as to how best to implement it's access to X11 calls. My current thoughts on how to do this are given below. Are they reasonable?? I need to access a number of X11 calls, largely in the XInput extension. None of these are exposed by the x11drv dll. My intention is currently to change nothing in the x11drv dll. The only hints I can find about how to do this are from the direct draw and open gl dlls. These dlls can do the following: Get the X11 Display object of a gdi context. Get the X11 window handle given a win32 window handle. Synchronise with the x11_drv code for multi threading. My wintab code will do the same. The one difference will be that wintab will create it's own X11 Display objects. It will interrogate a gdi's X11 Display object to ensure it talks to the same screen. The wintab code will also require multiple message queues. To implement this I intend to use one display object per queue. (Much as wine uses one display object per thread) Hope I'm on the right track -Rob.

Hmm, I'm not sure whether we should increase the preexisting Filesystem type mess by doing that. I've hated the "win95", "vfat" etc. syntax almost from the beginning (well, to be fair, I think I'm not too innocent when it comes to its implementation, but at some time I just came to the conclusion that it sucked) After all we're running on *Unix* file systems in many cases, so "win95" does have no place here at all ! (neither does "vfat") Not to mention that "win95" awfully collides with the "win95" winver... And adding yet another "incorrect" "ntfs" setting makes my head want to go bonkey ;-) So I guess that it might be a good idea to think about how to solve this configuration issue in a nicer way (and of course keep the old config capabilities for about 2 years in order to have backward compatibility). We might even want to think of introducing "nameless" filesystem type settings (instead of having "broken" conflicting and "wrong" FS type names). And of course it seems as if we also need a separate FS *name* setting in order to have Wine return "NTFS" instead of "FAT" in your case... So could we start a discussion about that perhaps ? > Files changed: documentation/samples/config > documnetation/configuring.sgml > files/drive.c Finally a beautifully implemented patch ! I hate having to clean up the docu "after the fact". > -;; DON'T use "unix" unless you intend to port programs using Winelib ! > +;; - "ntfs" for ext2fs (some program need this to write files > 2GB) ^^^^^^^^ urks ! a significant portion of unix FS users don't even use ext2fs... > +;; - "unix" DO NOT USE unless you intend to port programs using Winelib !

'95 and 2000 conformance test results
by Susan Pierce 15 Jan '03

15 Jan '03

Hello, I've attached the results of my Wine conformance testing. I'm sending in my text based Wordpad files because I did not see a recommended format for result submission. Is there one? I briefly considered hacking the html table and returning that as an attachment. Then I gave up and decided you would just like the info. Also, there is a problem on both my machines when I display the nice table of results: ntdll/rtlbitmap, ntdll/rtlstr, oleaut32/safearray, oleaut32/vartest, and rpcrt4/rpc show up in the html source but are not displayed by IE. I stared at the source for a while but I do not know enough html to be dangerous, let alone figure it out. I've downloaded the Wine source and thought I'd try my hand at fixing some of the problems. This has been fun. Thanks, Susan

Two Simple Qs ?

Hi all, As most of you know, the client needs to send some requests to accomplish some special tasks which could not be handled by the client itself. Qs: 1. Why this could not by the client itself ? [may be it is better to save memory by centelizing the shared code in the server ] 2. How and when the server is loaded?

Winedbg: Open Xterm when Controlling console no more available
by Uwe Bonnes 14 Jan '03

14 Jan '03

Hallo Eric, another winedbg feature request: When the starting application spawns off other processes and exec itself, with the other spawned processes still running, and one of these processes crashes, and winedbg is configured to work on the starting console, winedbg starts, loads all dll, but then exits immediate due to the missing console. In this situation, winedbg should test if console access is still possible, and when not, it should start magically an xterm. I still prefer to use the console for winedbg interaction, as scrolling is easier.

Wine and Windows error code
by mpfbk＠free.fr 14 Jan '03

14 Jan '03

Tests of win32 API returned error codes inside Wine This subject has maybe been treated before, sorry if it has already been discussed and closed. Running the following simple and standard program, nothing special happens: the windows opens itself, it can be closed with the close button, and the message box is displayed when the left mouse button is pressed inside the window. /* * testbed1_ref.c * */ #define STRICT #include <windows.h> const char g_szClassName[] = "testbed1WindowClass"; /* ============================================================ */ static void ErrorBox(LPCSTR msg) { LPVOID error_msg; DWORD error_code; char error_buffer[256]; error_code = GetLastError(); FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM, NULL, error_code, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPTSTR) &error_msg, 0, NULL ); /* TBC: should be snprintf */ sprintf(error_buffer, "%s: %d:%s", msg, error_code, error_msg); MessageBox(NULL, error_buffer, "Error!", MB_ICONEXCLAMATION | MB_OK); LocalFree( error_msg ); } /* ============================================================ */ LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) { switch(msg) { case WM_LBUTTONDOWN: { char szFileName[MAX_PATH]; HINSTANCE hInstance; if(IsDebuggerPresent()) { MessageBox(NULL, "Running under debugger control", "Debug!", MB_ICONINFORMATION | MB_OK); } else { OutputDebugString(TEXT("No debugger, but 'OutputDebugString' works, since you see this (in DBWin32 for instance)")); } hInstance = GetModuleHandle(NULL); GetModuleFileName(hInstance, szFileName, MAX_PATH); MessageBox(hwnd, szFileName, "This program is:", MB_OK | MB_ICONINFORMATION); } break; case WM_CLOSE: DestroyWindow(hwnd); break; case WM_DESTROY: PostQuitMessage(0); break; default: return DefWindowProc(hwnd, msg, wParam, lParam); } return 0; } /* ============================================================ */ int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { WNDCLASSEX wc; HWND hwnd; MSG Msg; /* Register the Window Class */ wc.cbSize = sizeof(WNDCLASSEX); wc.style = 0; wc.lpfnWndProc = WndProc; wc.cbClsExtra = 0; wc.cbWndExtra = 0; wc.hInstance = hInstance; wc.hIcon = LoadIcon(NULL, IDI_APPLICATION); wc.hCursor = LoadCursor(NULL, IDC_ARROW); wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1); wc.lpszMenuName = NULL; wc.lpszClassName = g_szClassName; wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION); if(!RegisterClassEx(&wc)) { ErrorBox("Window Class Registration Failed!"); return 0; } /* Create the Window */ hwnd = CreateWindowEx(WS_EX_CLIENTEDGE, g_szClassName, "The title of my window", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, 240, 120, NULL, NULL, hInstance, NULL); if(hwnd == NULL) { ErrorBox("Window Creation Failed"); return 0; } ShowWindow(hwnd, nCmdShow); UpdateWindow(hwnd); /* Run Message Loop */ while(GetMessage(&Msg, NULL, 0, 0) > 0) { TranslateMessage(&Msg); DispatchMessage(&Msg); } return Msg.wParam; } What is a little bit unusual is the ErrorBox function : often, a message box simply reports the error and aborts the program. ErrorBox uses GetLastError() and FormatMessage() to provide somewhat more information. By accident, let's make an error, commenting out the RegisterClassEx() call : #if 0 if(!RegisterClassEx(&wc)) { ErrorBox("Window Class Registration Failed!"); return 0; } #endif Under Windows (tested with NT4 and XP), the displayed message (by ErrorBox) is: == Window Creation Failed: 1407: Can't find window class == But, under wine (20021219), the displayed message is, unfortunately : == Window Creation Failed: 0: No error == While looking inside the wine sources, it appears that no error code is set in the functions 'CreateWindowExA' in windows/win.c file when the window's class is not found : an error message is printed and 0 is returned. The following adds the appropriate error code in function CreateWindowExA : around line 1291 and 1301: SetLastError(ERROR_CANNOT_FIND_WND_CLASS); before the return 0; Questions : does it have any interest for wine to add these error codes ? If yes, according to DLL separation, is it allowed to call SetLastError() in any context ? Should I submit a patch ? Any other feedback ?

Wine, Mozilla & IE ?
by Juan Rey Saura 14 Jan '03

14 Jan '03

Hi ! I've read in the list there is a project about compiling Mozilla under Wine, I think it would be great. Several parts of wine need an IWebBrowser implemtation; CHM support, some applications... One implementation based on the khtml is in the works, but Mozilla does implement it yet ( see http://www.iol.ie/~locka/mozilla/mozilla.htm ). Could Mozilla, under Wine or maybe native version, be used as a replacement for the IE IWebBrowser implementation?
