MS' hidden API
by Zhang Shu 09 Jul '02

09 Jul '02

Dear wine developers, I have one question on the development of wine. Long(one or two years) ago I've heard that Microsoft got some hidden APIs in their products of various windows, and they use these APIs in their own applications. I wonder if this is still a problem on their recent product like windows XP. If it is, I guess wine will not be able to run such MS applications which uses hidden APIs. Is this right? And, is wine designed(or its goal is) to run all applications(including MS product and non-MS product) that runs on windows? Please forgive me if this problem has appeared in the past. I just joined this list a couple of days ago. Thank you. Regards, -- Zhang Shu

dynamic .fon conversion
by David Chow 03 Apr '02

03 Apr '02

Hi, I am new to Wine develop, I wish to investigate and join, the following is the topic I am interested in. Does Wine develpers planning to implement .fon files support? I mean loading it dynamically? Since Xfree86 4 supports true type fonts, and most of the Linux distribution are now using XFree86-4 . We can actually load these fonts into the Xsever dynamically at run time providing we have some dynamic conversion between the font files. David

Unicode, i18n support
by Francois Gouget 03 Apr '02

03 Apr '02

Bug 98 - Unicode, i18n support is quite vague. How could I flesh it out? For instance I am thinking that we could convert this into a metabug and have one sub bug for each control that still needs to be unicodified. So: * which are the common controls that still need to be unicodified? * are there other controls that need to be unicodified * do common dialogs need work? As usual the goal is to make the individual tasks more visible so as to give inspiration to potential contributors, and so that we have a better idea of our progress and what remains to be done. Another issue, which would fall more in the i18n part is BiDi support. What is the scope of this? Does it require modifications of all the controls like unicode? http://www.winehq.com/hypermail/wine-devel/2002/03/0236.html Shachar, it sounds like you started working on this, should I say so when I create a bugzilla task for this? Even better, can I assign the task to you? (it can always be reassigned later, it's just a more flexible way of doing things). -- Francois Gouget fgouget(a)free.fr http://fgouget.free.fr/ Broadcast message : fin du monde dans cinq minutes, repentez vous !

CreateProcess design
by Eric Pouech 01 Apr '02

01 Apr '02

before latest Alexandre patch, CreateProcess was able to use stuff like: CreateProcess(NULL, "foo.exe --wine_opt -- --foo_opt") --wine_opt was seen by foo as options for wine, whereas foo_opt could be a command line option for foo (in foo, the command line would only be "--foo_opt") since last night, this is broken: - --wine_opt is still seen as a wine option - however, the command line passed to foo isn't cleaned up... we get the whole line "--wine_opt -- --foo_opt"... what should we do. I think Alexandre long term option is to really get rid of the options on the command line and use the WINEOPTION(S) env var (we could still have a wrapper script to do the conversion) should we adopt this right away or clean up the command line option ? as a consequence, you no longer can use any CUI program in the user/graphical mode, including winedbg - it still work as a unix console though A+

make test leaves 2 wine processes running
by Sylvain Petreolle 01 Apr '02

01 Apr '02

Hi, Running make test with a desktop window leaves ok but 2 processes are still running and the desktop windows not closed. They cannot be closed when I use the cross or the close command, i must kill them. (don't have to use -9 parameter) Running processes are : /home/wine/wine tests/vartest.c /home/wine/wine tests/sysparams.c (wineserver is here) I tried to winedbg them, but got error when I typed attach : error 5 (ERROR_ACCESS_DENIED). ___________________________________________________________ Do You Yahoo!? -- Une adresse @yahoo.fr gratuite et en français !

problems with the alt button and window switching
by Rizsanyi Zsolt 31 Mar '02

31 Mar '02

Hi! If I change the window with keyboard (eg with ALT-TAB), then when I switch back to the wine window wine still thinks that the ALT button is depressed. I happens, because the key event of pressing ALT arrives to the wine window before the switch. And I see in the console (with --debugmsg +key) the next lines: trace:key:X11DRV_KeyEvent state = 10 trace:key:X11DRV_KeyEvent KeyPress : keysym=FFE9 (Alt_L), ascii chars=0 / 0 / '' trace:key:X11DRV_KeyEvent keycode 0x40 converted to vkey 0x12 trace:key:X11DRV_KeyEvent bScan = 0x38. trace:key:queue_kbd_event wParam=0012, lParam=20380001, InputKeyState=81 trace:key:TranslateMessage (WM_SYSKEYDOWN, 0012, 20380001) trace:key:TranslateMessage Translating key VK_MENU (0012), scancode 38 trace:key:X11DRV_ToUnicode (0012, 2038) : faked state = 10 trace:key:X11DRV_ToUnicode ToUnicode about to return 0 with char bbc6 trace:key:queue_kbd_event wParam=0012, lParam=c0000001, InputKeyState=1 That is the key state has been changed. And when I return to the wine window (by keyboard or mouse) it acts like if the ALT button were depressed. The solution is that the key states should be reset when the wine gets back the focus or loses the focus. That is more exactly in windows/winpos.c in the function WINPOS_SetActiveWindow when the hWnd is NULL ! That is the case when switching from a wine window to an non-wine window. So I have found the place :), just I dont know whats the preferred way to reset all the key states to not pressed. I have added the next few lines: --- oldwinpos.c Fri Mar 29 16:54:59 2002 +++ winpos.c Fri Mar 29 16:55:08 2002 @@ -1217,6 +1217,12 @@ if ((wndPtr = WIN_FindWndPtr(hWnd))) hWnd = wndPtr->hwndSelf; /* make it a full handle */ + /* reset key states when switching to a non-wine window */ + if (hWnd == 0) + { + InputKeyStateTable[VK_MENU] &= ~0x80; + goto CLEANUP_END; + } + /* paranoid checks */ if( hWnd == GetDesktopWindow() || (bRet = (hWnd == hwndActive)) ) goto CLEANUP_END; And now my problem is fixed. But I have experienced the same problem with the Control button (altough it is harder to reproduce). So maybe all the key states should be reset. So I would like to have this patch or something similar in wine. Best regards Zsolt Rizsanyi

WineLib newbie question
by Boris Buegling 31 Mar '02

31 Mar '02

Hi all. I'm wondering how difficult it is to port an application to Linux with WineLib. There are quite a few N64 emulators with source code on Windoze and I want to port one of them to Linux, because there is no decent native emulator, First, is it possible that things which don't work well with Wine, work when they are ported using WineLib ? Second, how much work is involved ? Regards, -- Boris Buegling <boris(a)icculus.org> "Sleep less - live longer." - "Ok good, 1 down...

DIB engine
by Francois Gouget 31 Mar '02

31 Mar '02

The DIB engine was discussed quite a lot at WineConf. I am now trying to summarize these discussions to update bug 421 - Implement a DIB engine. http://wine.codeweavers.com/bugzilla/show_bug.cgi?id=421 Is the following accurate, complete, etc? Comments? Other ideas? Any volunteers? This was discussed quite a bit at WineConf. Ideas that were floated around are: 1. Have X export the required API --------------------------------- XFree86 4 has all the needed code, for all bit depths and layouts we care about. We could try to have the X guys export this in the form of an API ala Xft. Wine could then link with this library to implement the DIB engine (or dlopen that library). * Is the needed API already available? * If not, are the XFree86 guys willing to export it? * Almost everyone is using XFree86, but what about people who don't (embedded devices, Wine on Solaris...). We need a fallback. * We won't have to maintain that code which is a good thing, although it is not supposed to change much once written. * Will we be able to do all that we need with that API? Probably yes since it can be expected to match the X API quite closely and we are abel to use the X API. 2. Copy the relevant X code into Wine ------------------------------------- Since X has all the code and that code is under the X11 license we could copy it all into Wine. * This means we will have to maintain the code ourselves, although it is not supposed to change much once written. 3. Copy the relevant code from MicroWindows/NanoGUI to Wine ----------------------------------------------------------- MicroWindows/NanoGUI also has code that could help us bootstrap our DIB engine. We probably don't want Wine to depend on these projects but we could copy their code into Wine. * Are the licenses compatible? * Do they support all the bit depths and layouts we care about? * This means we will have to maintain the code ourselves, although it is not supposed to change much once written. 4. Copy the relevant code from GGI to Wine ------------------------------------------ GGI also has similar code. Again we probably don't want to introduce a dependency on GGI so the same questions apply: * Are the licenses compatible? * Do they support all the bit depths and layouts we care about? * This means we will have to maintain the code ourselves, although it is not supposed to change much once written. -- Francois Gouget fgouget(a)free.fr http://fgouget.free.fr/ "Utilisateur" (nom commun) : Mot utilisé par les informaticiens en lieu et place d'"idiot".

Seems like the file isn't being created. (Uwe Bonnes helped me with this). But we disagree what part of WINE (or outside WINE) is wrong. The first part of the log shows a CreateFileA that is unable to create a file. This API works fine when the file is in the same dir as the application (had tested it). The second part of the log shows the last screen I get after start the program (MessageBox API). MFRTS32 is a .dll the program calls. We thougth of there too. But this program works under Windows. Everything is in the path. Both wine.conf and Linux. I could reproduce the error in Win2k this way: Created a set of programs (L1, L2 and L3) that will run one after one with conditions. If the field in L1 is fulfilled then we jump directly to L3. Else We fulfill the field in L2 and then jump to L3. In details: L1 would creates a file with a name if the filed is fulfilled an L3 NEEDS to know that name. If we had to run L2 then the file will be with another name and L3 will get data from that file. But the file ins't created in neither of the cases. So a screen shows up: "External path string <G-PATH> not found. File FILE-LINUX." That message is the same I get under WINE: "External path string <UPCW56-DEV-DATA-DIR> not found. File IYF029." Refers to a file (IYF029), that exists (located in the ./data dir) but was not filled with data it need to work, or incorretly filled. Both G-PATH and UPCW56-DEV-DATA-DIR are variables of a file that has a number of them inside. As here we use APIs I'll list 2 of them that are used within the function and their definiton, took from MSDN: CreateProcess CreateProcess( LPCWSTR lpszImageName, LPCWSTR lpszCmdLine, LPSECURITY_ATTRIBUTES lpsaProcess, LPSECURITY_ATTRIBUTES lpsaThread, BOOL fInheritHandles, DWORD fdwCreate, LPVOID lpvEnvironment, LPWSTR lpszCurDir, LPSTARTUPINFOW lpsiStartInfo, LPPROCESS_INFORMATION lppiProcInfo); ........ StartupInfo.dwFillAttribute dwFillAttribute Ignored unless dwFlags specifies STARTF_USEFILLATTRIBUTE. Specifies the initial text and background colors if a new console window is created in a console application. These values are ignored in GUI applications. This value can be any combination of the following values: FOREGROUND_BLUE, FOREGROUND_GREEN, FOREGROUND_RED, FOREGROUND_INTENSITY, BACKGROUND_BLUE, BACKGROUND_GREEN, BACKGROUND_RED, and BACKGROUND_INTENSITY. For example, the following combination of values produces red text on a white background: FOREGROUND_RED| BACKGROUND_RED| BACKGROUND_GREEN| BACKGROUND_BLUE OBS.: We do NOT use this to send this kind of attributes. We DO send more data as we saw that it handles well. We also DO use this in gui applications. typedef struct _STARTUPINFO { DWORD cb; LPTSTR lpReserved; LPTSTR lpDesktop; LPTSTR lpTitle; DWORD dwX; DWORD dwY; DWORD dwXSize; DWORD dwYSize; DWORD dwXCountChars; DWORD dwYCountChars; DWORD dwFillAttribute; DWORD dwFlags; WORD wShowWindow; WORD cbReserved2; LPBYTE lpReserved2; HANDLE hStdInput; HANDLE hStdOutput; HANDLE hStdError; } STARTUPINFO, *LPSTARTUPINFO; ............... CreateFile HANDLE CreateFile( LPCTSTR lpFileName, // file name DWORD dwDesiredAccess, // access mode DWORD dwShareMode, // share mode LPSECURITY_ATTRIBUTES lpSecurityAttributes, // SD DWORD dwCreationDisposition, // how to create DWORD dwFlagsAndAttributes, // file attributes HANDLE hTemplateFile // handle to template file ); .................. Any thoughs? Thanks, Ricardo.

Improving the regression testing infrastructure
by Geoffrey Hausheer 30 Mar '02

30 Mar '02

I know regression testing isn't as interesting as doing real development, and so I appologize with once again spamming the list with regression questions... As I've been writing tests (only for the last week or so), I realized that as we get a lot more tests, it will be very difficult to keep track of what is being tested, and what is not. I'd like to propose a list of which functions for each DLL are being tested, which file tests it, as well as any comments on the current tests. Currently, there is no great way to do this. I may use several functions in a directed test which I am not actually testing (for instance I've found it necessary to retrieve the page-size using GetSystemInfo, but my tests have nothing to do with this function, and so writing a directed test for it is a task for another day). Thus just grepping for which functions are used in a test is not sufficient. Also, I have found that some functions, or even specific task functions are very difficult to test, and so I've been leaving these out so that perhaps people ore skilled than myself could take a crack at them late (A good example is testing inheritance with CreateThread. It is a task that is beyond my capabilities at the moment, at least until I can find a good way to test CreateProcess...this would be much easier if Windows had something equivalent to 'fork'). In any case, I've tried to be thorough about commenting what I do and don't test, but it would be a lot more convenient if this information was more easily parsed than trying to find my comments intersperesed through the tests. So does anyone thing that creating a easily parsable list with the state of the current tests is this a reasonable thing to do, and would creating a simple file in each /tests directory with the information be good enough? If so, I can add one to my next test, and update it with what I've done so far. In general, while Francois' presentation is a good place to get started, I think it'd be a lot easier if there was a document off of winehq with recommendations on how to build, test, and document tests. Lowering the difficulty threshold, is more likely to draw more people to do so. Thanks, .Geoff
