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

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...

Re: advpack: Only do_ocx_reg (and thus DllRegisterServer) from RegisterOCX when 'N' is passed as a flag. Clarify documentation.
by James Hawkins Sept. 24, 2011

I'm very hesitant about this. MSDN has no documentation about RegisterOCX, so I'm not sure how you're justifying this change. It's been a long time since I worked on this, so I don't remember much, but I do remember testing this method and documenting the parameters correctly. Where are you getting information that 'I' is required when using 'N'?

GSoC-2011: Implement Missing Mesh Functions in Wine’s D3DX9
by Michael Mc Donnell Aug. 25, 2011

Aug. 25, 2011

Dear Wine developers, I would like implement some of the missing mesh functions in Wine's D3DX9 for Google Summer of Code 2011. I would like to implement the following functions: - CloneMesh - CloneMeshFVF - ConvertPointRepsToAdjacency - ConvertAdjacencyToPointReps - GenerateAdjacency They seem to be suitable in size to implement during a summer, and I have a good idea of how to implement them. I expect to first implement tests and then implement the functions. I am a masters student at the Technical University of Denmark nearing the end of my studies, and I have specialized in 3D computer graphics, studying both real-time and physically based techniques, as well as how to use existing 3D modeling tools to create animations. The mesh functions should be fairly straight forward for me to implement as I have recently taken an advanced course on geometry processing which involved a lot of mesh manipulation. I have, furthermore, already tests (for a shell32 function) in the wine test suite so I have some knowledge of Wine development. Roderick Coldenbrander is listed as a possible mentor for "Direct3D - Implement missing D3D9_xx DLLs" on the wiki. Are you still interested, or would someone else like to be a mentor? Regards, Michael Mc Donnell

CD-ROM ioctl support on MacOS?

Hi guys, I've put together the following doc for the introduction of message contexts. It's still a bit raw but I'd improve it for the wiki version. Could you please have a look and help proofread it? I'd like to ensure I didn't miss an important step. Thanks in advance. Frédéric Delanoy PS: BTW what is the reference version? en_US.po or en.po? ********* Adding one/more message contexts (ADD LINK TO EXTERNAL DOC) (QUICK MC EXPLANATION) Prerequisite: enable maintainer mode using ./configure --enable-maintainer-mode (you might have to add some development packages; check with your distribution for infos). 1. Locate strings to be "altered" Say you have in your localized po file: #: file1.rc:123 file2.rc:456 msgid "ambiguous word" msgstr "translation" and you want to disambiguate, you'd do the following 2. Find appropriate translations - check the respective rc entries (in file1.rc line 123) FOO "ambiguous word" (in file2.rc line 456) BAR "ambiguous word" and find their meaning/context (e.g. using some code browsing tools, like cscope to find references; running the program is recommanded, ...) 3. Add the messages contexts - The following syntax is used: "translation" -> "#msgctxt#your context#translation" - You end up with sthg like FOO "#msgctxt#context #ambiguous word#" Similarly BAR "#msgctxt#context 2#ambiguous word#" 3. Run 'make depend && make' 4. Edit your po file to add the new translations 5. Ideally, remove the "#, fuzzy" automatically inserted in the En_US.po reference file (and En.rc ). 6. Run 'make' again and test your changes.

D3D performance debugging report
by Stefan Dösinger May 2, 2011

May 2, 2011

Hi, I spent a few hours debugging wined3d performance today. No, I found no magic fix for the slowness, just some semi-usable data. First I wrote a hacky patch to avoid redundant FBO applications. This gave a tiny, tiny performance increase, see http://www.winehq.org/pipermail/wine- devel/2011-April/089832.html. The main investigation concerned redundant shader applications. The aim was to find out how many of our glBindProgramARB calls are re-binding the same program, and how much this costs. Depending on the game between 20% to 90% of all BindProgram calls are redundant. I'll attach my debug hack so others can test their own apps. I used ARB shaders for testing because they can apply vertex and fragment programs separately. This brings up two questions: (a) How much does this cost (b) Why does this happen The costs: In my draw overhead tester hacking out the redundant apply calls improved performance a lot, from about 101 fps to 157 fps. The biggest part of that are the GL calls. Without them but the remaining shader logic I get 144 fps. Unfortunately this does not translate to any performance gains in real apps. I tried to filter out the redundant apply calls in the simplest way possible: Track the current value per wined3d_context and check before calling glBindProgramARB. This gave the 144 fps in the draw overhead tester, but no measurable increase in any other apps(I tested StarCraft 2, HL2, Team Fortress 2, World in Conflict and a few others) Given the amount of redundant apply calls and the cost of them in the draw overlay tester I have expected at least some improvement. Certainly not a 50% performance increase(the draw overlay tester performs no shader changes at all in the draw loop), but at least a 2-3% gain. So far I have no explanation why I didn't see that. But why do those redundant apply calls happen? It seems like the state dirtification comes all the way from the stream sources and/or vertex declaration. STREAMSRC is linked to VDECL, which is linked to VERTEXSHADER, which in turn reapplies the pixel shader. This means redundant vertex and pixel shader applications. Separating those states will be a major challenge. The vdecl<->vshader link shouldn't be needed any more, except in rare cases where GL_ARB_vertex_array_bgra is not supported and the application switches one attribute from D3DDECL_D3DCOLOR to a non-d3dcolor attribute. If the vertex shader changes we still have to reparse the vertex declaraion and reapply the stream sources because the vshader determines the stream numbers. Maybe we can reduce the number of times this happens by ordering stream usages and indices to make sure shaders with compatible input get the same stream ordering. vdecl and streamsrc are pretty related. If the vdecl is changed we have to reapply the stream sources. The other way around shouldn't cause problems though. There's no need to reapply every stream except the changed ones and there's no need to reapply the vertex shader. The vertex and pixel shader are linked for a few reasons: The shader backend API offers only a function to set both. Basic GLSL only offers a function to set both at once(GL_ARB_separate_shader_objects changes that). And even in ARB the pixel shader input may require some changes in the vertex shader output to get Shader Model 3.0 varyings right. The shader backend API can be changed, but it has to be done in a way that doesn't hurt GLSL without ARB_separate_shader_objects. If we have classic GLSL we have to keep the link. With ARB we can conditionally reapply the vertex shader if the ps_input_signature is changed. To complicate matters there are additional states that affect the shaders, like fog, textures, clipping. We don't keep track of those dependencies. So it's a lot of work to clean up these state dependencies and we don't know how much it'll gain us :-( Stefan

gecko and native msvcrt
by Dan Kegel April 30, 2011

April 30, 2011

While testing a game with current gecko, I saw the error wine: Call from 0x7bc4ad90 to unimplemented function msvcrt.dll._snwprintf_s, aborting The game needed a native msvcrt, so I had installed one with winetricks, and it didn't export that function. So it seems that new gecko is incompatible with old msvcrt, and using native msvcrt as a workaround for bugs in wine's version is going to be harder than it used to be. Time to fix more of them msvcrt bugs, I guess... And/or find a more up to date msvcrt.dll for winetricks.

comctl32: realloc or free and alloc
by Alexey Fisher April 30, 2011

April 30, 2011

Hallo, i currently digg in comctl32 to find why my app fails. I found that string conversation AtoW in some places silently fails. The problem is that the destination for string is just a fresh pointer (not NULL). Str_SetPtrAtoW check if it is NULL pointer and if not it trys to ReAlloc. There was no Alloc before so ReAlloc returns NULL. Because there is no other checks, Str_SetPtrAtoW just go back without converting the string. Here is affected code: dlls/comctl32/comctl32undoc.c:999 > BOOL Str_SetPtrAtoW (LPWSTR *lppDest, LPCSTR lpSrc) > { > TRACE("(%p %s)\n", lppDest, lpSrc); > > if (lpSrc) { > INT len = MultiByteToWideChar(CP_ACP,0,lpSrc,-1,NULL,0); > LPWSTR ptr = ReAlloc (*lppDest, len*sizeof(WCHAR)); > > if (!ptr) { > ERR("last error %x\n", GetLastError()); > return FALSE; > } > MultiByteToWideChar(CP_ACP,0,lpSrc,-1,ptr,len); > *lppDest = ptr; > } > else { > Free (*lppDest); > *lppDest = NULL; > } > > return TRUE; > } The question is, is it appropriate reaction of ReAlloc and if it so, may be it make more sense to do this: --- a/dlls/comctl32/comctl32undoc.c +++ b/dlls/comctl32/comctl32undoc.c @@ -998,18 +998,26 @@ INT Str_GetPtrAtoW (LPCSTR lpSrc, LPWSTR lpDest, INT nMaxLen) */ BOOL Str_SetPtrAtoW (LPWSTR *lppDest, LPCSTR lpSrc) { - TRACE("(%p %s)\n", lppDest, lpSrc); + TRACE("(%p, %s)\n", *lppDest, debugstr_a(lpSrc)); if (lpSrc) { + if (*lppDest) { + Free (*lppDest); + *lppDest = NULL; + } INT len = MultiByteToWideChar(CP_ACP,0,lpSrc,-1,NULL,0); - LPWSTR ptr = ReAlloc (*lppDest, len*sizeof(WCHAR)); + LPWSTR ptr = Alloc (len*sizeof(WCHAR)); - if (!ptr) + if (!ptr) { + ERR("Can't allocait memory size: %u," + " for string %s.\n", len*sizeof(WCHAR), lpSrc); return FALSE; + } MultiByteToWideChar(CP_ACP,0,lpSrc,-1,ptr,len); *lppDest = ptr; } else { + TRACE("lpSrc = NULL, nothing to convert.\n"); Free (*lppDest); *lppDest = NULL; } -- Regards, Alexey

Note that if you're running into this code you probably have problems elsewhere though.
