Error handling in RpcBindingVectorFree (dlls/rpcrt4/rpc_binding.c)
by Gerald Pfeifer Nov. 22, 2020

Nov. 22, 2020

Looking at RPC_STATUS WINAPI RpcBindingVectorFree( RPC_BINDING_VECTOR** BindingVector ) { RPC_STATUS status; ULONG c; TRACE("(%p)\n", BindingVector); for (c=0; c<(*BindingVector)->Count; c++) { status = RpcBindingFree(&(*BindingVector)->BindingH[c]); } HeapFree(GetProcessHeap(), 0, *BindingVector); *BindingVector = NULL; return RPC_S_OK; } we currently always ignore the outcome of RpcBindingFree and return RPC_S_OK. However, there is one case where RpcBindingFree returns something different (which is if *Binding is null when RPC_S_INVALID_BINDING is returned). What is the proper way of handling this? Just keeping the code as is and removing the unused status variable? Breaking the loop once RpcBindingFree returns something different from RPC_S_OK? Continuing and returning the first / the last status different from RPC_S_OK? Gerald

ODBC Databases: Jet/Access success
by Barry Bird June 14, 2018

June 14, 2018

Good Afternoon. In section 3.3.6.2 of your User Guide you ask readers to report successes with databases other than MS SQL. Well here's one (I know Access 2000 can work with Wine, but this doesn't require Access): How to set up Wine to enable Windows programs that read and write to Jet (Access) databases using ODBC. I write such programs in C and use the API defined in ODBC API Reference http://msdn.microsoft.com/en-us/library/ms714562%28VS.85%29.aspx They work fine on Windows and only require Mingw to be installed to compile and link them, both for console programs and those using Windows SDK. You then can write interactive programs in C which use a full-featured SQL database which comes bundled with Windows. No need to purchase Access. With the set-up below they will also run on Linux (Kubuntu 9.04) and Wine 1.1.26. You need to update the registry to install the Access drivers. Under Windows, export from the Registry to *.reg files the registry entries - HKLM\Software\ODBC - HKLM\Software\Microsoft\Jet all subsidiary keys and values come with them. You can carefully edit these files to remove drivers and DSNs you don't need. Import these files using the registry editor in wine: wine regedit.exe. You need to bring across from Windows to Windows\System32 under wine: clbcatq.dll comres.dll expsrv.dll msjet40.dll mswstr10.dll msjter40.dll msjint40.dll msjtes40.dll msrd3x40.dll odbc32.dll odbccp32.dll odbcji32.dll odbcjt32.dll odbcad32.exe odbcint.dll odbctrac.dll vbajet32.dll Register this server in wine: wine regsvr32.exe msjtes40.dll No need to install MDAC. To use Windows ODBC drivers, you have to override Wine's odbccp32.dll and odbc32.dll with the native versions because the Wine versions are currently wired directly to Linux's unixodbc. This can be done by setting up the ODBC Data Source Administrator odbcad32.exe using winecfg: - Add the program to the Applications tab - then in the libraries tab, pick from 'New override for library' drop-down odbc32.dll and odbccp32.dll add them and edit them to be Native for Windows. Then if you do wine odbcad32.exe this brings up the ODBC Data Source Administrator window as in the Windows Control Panel If needed, set up (System) DSNs using this program. Bring across the programs and *.mdb database files from Windows. Using winecfg, you need to set up each program you want to run with overrides for odbc32.dll and odbccp32.dll (Applications and Libraries tabs) as above. The programs should then run as they did in Windows but perhaps a bit slower with: wine Odbc-prog.exe This has been tested twice on a clean .wine install. I cannot vouch for support of all API and SQL facilities however. I hope someone finds this useful. Barry Bird

IMM / IME work
by Aric Stewart June 16, 2016

June 16, 2016

Hello all, I know this will only interest a small portion of you but thought i would give a quick update on the state of IMM32 since I have brought it to a major milestone. All the main patches are in which now separate IMM32 and IMEs. There is still more work to do but the major framework is in place. X11 XIM processing should be unchanged. However wine can now begin to load native windows IMEs as well. I have tested with windows ATOK20 (a popular Japanese IME) and successfully had text processing in a fully IME aware application. There are still clear issues to resolve in many aspects of this processing but we have forward progress. ImmInstallIME does not work yet, nor does switching keyboards. So to get the native IME to work you need to add this registry key. [System\\CurrentControlSet\\Control\\Keyboard Layouts\\<keyboard layout>] "Ime File"=<IME filename> so for example for ATOK20 in Japanese i used. [System\\CurrentControlSet\\Control\\Keyboard Layouts\\e0010411] "Ime File"="ATOK20W.IME" I would love to hear how well things work. I am sure using native IMEs will quickly show us many places where IMM32 needs to be improved. One issues I am going to investigate next is that sometimes non x11drv ime initialization, if occurring too early, causes x11drv to fail to create windows. I have not investigated with the latest changes to xim.c (which may already correct this problem) but if you see this problem this patch may help and i believe the IME_UpdateAssociation(NULL) is already unneeded. diff --git a/dlls/winex11.drv/xim.c b/dlls/winex11.drv/xim.c index d4df9f7..0c98136 100644 --- a/dlls/winex11.drv/xim.c +++ b/dlls/winex11.drv/xim.c @@ -475,7 +475,6 @@ static void X11DRV_OpenIM(Display *display, XPointer ptr, XP XUnregisterIMInstantiateCallback(display, NULL, NULL, NULL, X11DRV_OpenIM, wine_tsx11_unlock(); IME_XIMPresent(TRUE); - IME_UpdateAssociation(NULL); } thanks, -aric

DirectInput already has some internal abstraction layers for differnet joystick APIs, and has basic support for OSX joysticks.

What happened to the Fedora packages?
by Neal Gompa Aug. 2, 2014

Aug. 2, 2014

What happened to the Fedora packages? They have not been updated since 0.9.2!!!! Right now it is at 0.9.10!!! Nearly every other Linux distro supported has the up to date packages!!! And why does the Red Hat packages site not go to the SourceForge site as it does for SUSE packages and the others?? I have not really had the guts to ask until now, because I thought that maybe there was a slump, but now, its getting annoying!! And Fedora just released Fedora Core 5 yesterday!!! Please tell me new packages will be ready soon!!! Compiling WINE always crashes my computer, so I prefer to use the RPMs...

Fixing conflicts between WineD3D and WGL
by Ken Thomases April 28, 2014

April 28, 2014

Hi, This email brings together several threads of conversation that have been spread across different bug reports. Sorry for the length. The problem: WineD3D is based on WGL (a.k.a. opengl32). As a consequence, it conflicts with application use of WGL in a number of ways. It's also limited by WGL, which doesn't allow for all of the behaviors of DirectDraw and Direct3D. https://bugs.winehq.org/show_bug.cgi?id=28869 WineD3D needs to make its own GL context current temporarily and then restore the previous GL context, but WGL requires a DC to restore it and the DC may no longer be valid. https://bugs.winehq.org/show_bug.cgi?id=29301 WineD3D changes the window style of the device window when it should not. It needs to do that in order to render to the full screen where WGL only allows full-featured rendering to a window. https://bugs.winehq.org/show_bug.cgi?id=2082 Again, WineD3D is rendering to a window when it wants to render full-screen. In this case, the affected apps create an owned window that sits in front of the device window, obscuring it. http://bugs.winehq.org/show_bug.cgi?id=29934 WineD3D sets a pixel format on the application window. This conflicts with a later attempt by the app to set a different pixel format on the window via WGL. I think the solution to these problems is for WineD3D to have an alternative path to set up its GL context. Henri and I have been discussing using Wine-specific extensions to WGL to do this. There's already the extension WGL_WINE_pixel_format_passthrough which provides the wglSetPixelFormatWINE() function which is just like GDI's SetPixelFormat() and WGL's wglSetPixelFormat() except it allows for changing the pixel format after it's been set once. WineD3D needs to change it even though WGL doesn't allow that. In some of the bug reports listed above, I've suggested adding new extensions or modifying WGL_WINE_pixel_format_passthrough. We probably need a more comprehensive approach. WGL exposes various pieces of state to the application. Ideally, WineD3D would not alter any of that state since such alterations are visible to the app and Direct3D doesn't do that on Windows. I'm not sure that's achievable but we should at least minimize such visible state changes to the extent we can. WGL state: * The DC pixel format. For window DCs (which I believe are the only ones of real interest), this is actually a property of the window, not the DC. Changed by SetPixelFormat(), wglSetPixelFormat(); exposed by GetPixelFormat(), wglGetPixelFormat(). * The current GL context for the thread. Changed by wglMakeCurrent(), wglMakeContextCurrentARB(); exposed by wglGetCurrentContext(). * The DC for the current GL context. Changed by wglMakeCurrent(), wglMakeContextCurrentARB(); exposed by wglGetCurrentDC(), wglGetCurrentReadDCARB(). The most important things to achieve are a) to not "consume" the only opportunity the app has to set the window's pixel format, and b) to restore the app's current GL context (and implicitly its DC) when returning control to it. I don't think it's necessary to avoid WineD3D ever changing WGL's notion of the current context. Certainly, while a WineD3D GL context is current, GL functions like glClear() will operate on WineD3D's context. If the app thinks its context is current and calls GL functions, its context better really be current. So, WineD3D really needs to restore the app's context before returning control (and it generally does, I think). If it's going to do that, then wglGetCurrentContext() will take care of itself. Same for wglGetCurrentDC(). Here's my proposal: Extension WGL_WINE_surface: HANDLE wglCreateSurfaceWINE(HDC hdc, int pixel_format); // if hdc is GetDC(<some normal window>), a window surface is created // if hdc is GetDC(0), GetDC(GetDesktopWindow()), or CreateDC("display", …), a full-screen surface is created. // once the surface is created, it no longer refers to hdc void wglDestroySurfaceWINE(HANDLE surface); HDC wglGetSurfaceDCWINE(HANDLE surface); // Returns a DC created for the surface. This is not the DC passed in to wglCreateSurfaceWINE(). void wglReleaseSurfaceDCWINE(HANDLE surface, HDC hdc); This is somewhat modeled on WGL_ARB_pbuffer. <http://www.opengl.org/registry/specs/ARB/wgl_pbuffer.txt> A surface represents a "place" where GL can render, a potential target for a context. It can correspond to a Win32 window or it can be a full-screen surface. A full-screen surface will likely be a platform window (X11 or Mac) managed by the graphics driver but won't be a Win32 window. It should not interfere with mouse events or focus. A surface has a pixel format, similar to a window. Even if the surface was created from a window DC, its pixel format is independent of the window's. Since a surface is created with a pixel format, it shouldn't be necessary to set one with SetPixelFormat() on a surface DC. If it helps keep WineD3D's code simpler, we could allow it. I'm not sure if it will be necessary to support changing the pixel format after it's been set, using wglSetPixelFormatWINE(), or if the surface should just be destroyed and recreated as necessary. Doing the latter may eventually allow the removal of wglSetPixelFormatWINE(). The lifetime of a surface controls whatever resources the graphics driver has to manage for it. For a normal window, this may include a drawable. For a full-screen surface, this would include any full-screen platform window it might have created. WineD3D would obtain a DC from a surface using wglGetSurfaceDCWINE() just as it now obtains one for a window using GetDC(). There can be multiple DCs for a given surface. In particular, a DC can only be used on a single thread, so multiple threads would each have to get their own DC. The different lifetimes of surfaces vs. surface DCs is why this proposal differs from my approach in bug 2082, where I proposed an extension which just added full-screen DCs without a corresponding full-screen surface object. Destroying a surface while it still has extant surface DCs results in undefined behavior. Once WineD3D has a surface DC, it should be able to work with it as it currently does with window DCs. wglMakeCurrent() with a surface DC will associate the context with the surface drawable. For a surface created from a window, this would work as it does now in the graphics drivers with the exception of how the drawable is looked up from the DC. For a full-screen surface, this would target whatever full-screen drawable the graphics driver provides (possibly a platform window). There's a wrinkle having to do with the pixel format. User32 and the wineserver use the fact that a window has a pixel format to compute the "surface region" for the top-level window. This is a different "surface" than the concept central to this proposal. This "surface" is used for client-side GDI rendering using the DIB engine. Maintaining a surface region is necessary to prevent the contents of the window surface buffer from being blitted on top of any 3D rendering done to the window. To keep that functioning, the graphics drivers will still have to inform user32 that 3D rendering is being done to the window. It can do that using the existing mechanism, but that's not currently reversible because it's tied to the pixel format and that's a permanent property of a window. We'd like it to be reversible, since WineD3D can stop targeting a window. I'm thinking of using a count in user32. Extension WGL_WINE_make_current: BOOL wglMakeContextCurrentWINE(HGLRC hglrc); The standard WGL function wglMakeCurrent() combines two operations. It sets the a GL context's drawable to the provided DC and it makes the GL context current for the thread. This new function, wglMakeContextCurrentWINE(), would only do the latter. It would make a GL context current for the thread without changing which DC it's associated with. Both the X11 and Mac drivers already maintain the necessary state to do that. They don't need to have the DC passed in again. (If a GL context is associated with separate draw and read DCs using wglMakeContextCurrentARB(), then this function will leave it associated with both DCs.) This allows WineD3D to faithfully restore the app's previously-current WGL context. This addresses bug 28869. I considered some other designs but I don't think they work well. I looked for a way to do without special DCs. We could directly specify a pixel format when creating a context rather than getting it from the window or surface via the DC. We could make a context current directly on a surface rather than a surface DC. Unfortunately, too much of WGL depends on having a DC. For example, ChoosePixelFormat() and wglSwapBuffers(). What do folks think? Any feedback would be appreciated. -Ken

Cross-regressions between wine and mesa: how to handle them?
by Ruslan Kabatsayev March 17, 2014

March 17, 2014

Hi all, I've come across a problem, which may be simplest to see in the following workability diagram, tested on GTAVC on a i915 machine: _____________________________________________ Mesa_\_Wine_|__1.3.21__|__1.5.17__|__1.5.24+_| ____9.0_____|____OK____|____OK____|___slow___| ___~9.1-____|____OK____|___slow___|___slow___| ___~9.1+____|____OK____|_GL_error_|_GL_error_| Here ~9.1- and ~9.1+ are bisected commits between 9.0 and 9.1, with "-" earlier commit and "+" later one. "slow" means slide show instead of normal animation. "GL error" is a set of errors like "err:d3d:device_clear_render_targets >>>>>>>>>>>>>>>>> GL_INVALID_FRAMEBUFFER_OPERATION (0x506) from glClear @ device.c / 677". Wine version 1.5.24+ means any wine newer than 1.5.24 up to 1.7.11. All these things are related to wine trying to use GLSL as much as possible, and Mesa trying to make it seem that it supports OpenGL 2+, even on chips like i915, which don't support it. For end user this looks like failing software, and moreover, it's not easy to understand which software does have bug. Wine perspective: On the one hand, wine seems to use what Mesa exposes. On the other, why use shaders for games which don't need them? Mesa perspective: On the one hand, it wants to advertise more support for latest OpenGL standards. On the other, why do it for very old HW which doesn't support it? So, I'm not sure where I should report these regressions - to bugs.winehq.org or to bugs.freedesktop.org? I remember some similar bugs reported to wine being closed as UPSTREAM (e.g. bug 33964), and fixed (or worked around?) in Mesa. But on the other hand, wine 1.3 worked perfectly for all Mesa versions - is it really Mesa fault that newer versions of wine don't work? Could someone please explain how to handle such situations? Regards, Ruslan
