Error handling in RpcBindingVectorFree (dlls/rpcrt4/rpc_binding.c)
by Gerald Pfeifer 22 Nov '20

22 Nov '20

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

ntoskrnl.exe: unimplemented function ntoskrnl.exe.IoGetDeviceInterfaces
by Qian Hong 28 Sep '18

Dear all, While test another online bank with wine ActiveX, I got an unimplemented fuction of ntoskrnl: IoGetDeviceInterfaces, I found it listed in http://source.winehq.org/WineAPI/ntoskrnl.html as a stup, so I can't understand this log: wine: Unimplemented function ntoskrnl.exe.IoGetDeviceInterfaces called at address 0x7b839552 (thread 0022), starting debugger... Grateful for any explain! env: wine1.3.12 on Ubuntu 10.04 Here are the steps: 1. install an ActiveX from https://e.bank.ecitic.com/perbank5/plugs/CNCBSecPkg_EN.exe $ rm -rf ~/.wine $ winetricks -q mfc42 $ wine CNCBSecPkg_EN.exe fixme:ole:DllRegisterServer stub fixme:win:DisableProcessWindowsGhosting : stub fixme:msg:ChangeWindowMessageFilter c057 00000001 fixme:msg:ChangeWindowMessageFilter c057 00000001 fixme:msg:ChangeWindowMessageFilter c057 00000001 fixme:ole:CoCreateInstance no instance created for interface {ea1afb91-9e28-4b86-90e9-9e9f8a5eefaf} of class {56fdf344-fd6d-11d0-958a-006097c9a090}, hres is 0x80004002 fixme:sfc:SfcIsFileProtected ((nil), L"C:\\Program Files\\\4e2d\4fe1\94f6\884c\7f51\94f6\5b89\5168\63a7\4ef6\\unins000.exe") stub fixme:win:WINNLSEnableIME hUnknown1 0x1011a bUnknown2 0: stub! fixme:win:WINNLSEnableIME hUnknown1 0x1011a bUnknown2 -1: stub! fixme:win:WINNLSEnableIME hUnknown1 0x1011a bUnknown2 0: stub! wine: Call from 0x7b839552 to unimplemented function ntoskrnl.exe.IoGetDeviceInterfaces, aborting wine: Unimplemented function ntoskrnl.exe.IoGetDeviceInterfaces called at address 0x7b839552 (thread 002b), starting debugger... wine: Call from 0x7b839552 to unimplemented function ntoskrnl.exe.IoGetDeviceInterfaces, aborting wine: Call from 0x7b839552 to unimplemented function ntoskrnl.exe.IoGetDeviceInterfaces, aborting 2. open the online bank entry with wine builtin IE, then IE will crash: $ wine iexplore https://e.bank.ecitic.com/perbank5/signIn.do Please checkout the full log here: http://pastebin.com/rbAg7gwj Should I file a singel bug in ntoskrnl component , or separate bugs, one for ntoskrnl and one for the IE crashing?

ODBC Databases: Jet/Access success
by Barry Bird 14 Jun '18

14 Jun '18

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 16 Jun '16

16 Jun '16

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

Speed of gdi vs opengl DirectDrawRenderer
by Jonas Maebe 11 Oct '15

11 Oct '15

Hi, I had a problem with Majesty Gold HD running at glacial speed on my machine (quad Core i5 2.9GHz, NVidia GeForce GT 750M 1GB, OS X 10.9.5). I'm using wine 1.7.35, but I've had similar problems with older wine versions. It's a DirectDraw7 game that has been partially remastered to run on modern systems, but still uses DirectDraw7. This is a common problem on Windows too, but generally can be resolved by telling the game to use the DirectDraw blitter (instead of blitting itself). That didn't help on Wine though. I profiled wine (Instruments time profile) and noticed that most time was spent in wined3d's convert_r5g6b5_x8r8g8b8. Replacing that routine with an optimized sse2 version from pixman did not make much of a difference. Then I discovered that if I told the game to render to a 16 bit instead of to a 32 bit surface, wine would let OpenGL handle the colour conversion. Unfortunately, while this significantly reduced wine's cpu usage, it by no means made the game any faster. Looking at the OpenGL Driver Monitor stats, it seems the cpu was simply waiting all the time on the GPU, probably while it was blitting all of those 1920x1080 images to the screen. Reducing the resolution to the lowest supported by the game (800x600) made it slightly faster, but not much. Next, I added the DirectDrawRenderer registry key and set it to gdi. Now, while it's still slow at 1920x1080, the game runs much faster at 800x600 and even still at 1024x768. Profiling the gdi renderer shows that it has way higher cpu usage than the OpenGL renderer (virtually all in convert_to_8888), but it seems that for some reason it has causes much less traffic to the GPU. The wiki's wording suggests the gdi renderer is deprecated though. Does that mean this qualifies as a bug in the OpenGL renderer (maybe it tries to update the screen more often than necessary, saturating the bus that way?), and are there any things I can try to narrow down why the gdi renderer is so much faster? I didn't immediately see where it blits things actually to the screen. Thanks, Jonas

[PATCH] Use asserts for mmap failure modes
by Michael Gilbert 26 Jul '15

26 Jul '15

Hi, Using exit in shared libraries is a discouraged practice, and wine's mmap implementation currently does that. I attach a proposed change using asserts instead. Let me know if you have any feedback. Best wishes, Mike (btw I'm the debian wine maintainer)

DirectInput already has some internal abstraction layers for differnet joystick APIs, and has basic support for OSX joysticks. Does DInput have enough capabilities to access all the Xbox controller's features? My gut says no, otherwise MS wouldn't have created a new lib. I guess its worth checking though.

Wine 64 bit
by Kevin Davies 05 Jun '15

05 Jun '15

Hello, Where would you find information on wine64 status for running 64 bit windows software under OSX. These days a lot of Windows programs are going 64bit to make use of the available memory. Its becoming necessary to have this capability. Many thanks Kevin

Wine Joysticks, seeking a plan
by Aric Stewart 06 May '15

06 May '15

Hi all, Ok I sat down with Ken (the benefits of being in the same office) and after a lengthy discussion I have come to terms with how it may not be the most ideal plan to put the joystick driver into the graphics driver. However I am still of the strong opinion that we need some sort of better joystick architecture and I know Alexandre is also of the like mindset. This was discussed back on 2005 and I know there was also recent discussion around BSD that also involves this. I also have an itch to start to poke at xinput, but I have no interest in poking at xinput with the current way joysticks are handled. When I was working on this driver thing Alexandre expressed he was pretty opposed to having a whole new set of platform specific wine drivers. (winejoystick_mac, winejoystick_linux, etc...) But if we at least did that we would reduce code duplication by not having the platform specific code duplicated in 2 (with xinput it would become 3) places and have it collected in one place. Now completely unresearched but it may be possible to make a single joystick driver, maybe replacing winejoystick.drv that would build only the platform code that is relevant. but before I do another big chunk of work I am seeking some community buy-in and not just discuss with with Alexandre. I understand if the USB driver path gets actually fleshed out and we try to support Joysticks via that then all this separate driver work would fall away and be replaced. We of course need to make sure we come up with a plan that Alexandre will approve of. Would a replacement winejoystick.drv that holds all the platform specific code be acceptable? Is there a case where we would want that driver to be able to build multiple platform code? Maybe Linux and Linux Input? I will admit I am pretty ignorant of the Linux side of this whole situation. Ideas? Comments? thanks! -aric
