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

ntoskrnl.exe: unimplemented function ntoskrnl.exe.IoGetDeviceInterfaces
by Qian Hong Sept. 28, 2018

Sept. 28, 2018

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 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

WineHQ upgrade breaking dinput8:dinput?
by Francois Gouget Aug. 7, 2016

Aug. 7, 2016

This is a truly weird one. dinput8:dinput start failing on the 17th, the day after WineHQ was upgraded: https://test.winehq.org/data/tests/dinput8:dinput.html What makes this weird is that: * There has been no change to these tests between bd332f53f2d7 and 966a07149a02. In fact the last patch goes back to 2013. So it's not a bad patch. * The failures happen on every 32 bit test environment, from XP to Windows 10, VM or not, TestBot or not. Only 64 bit is spared. * I compiled a dinput8_crosstest.exe binary bd332f53f2d7 which was not failing according to the test.winehq.org results. But all I got is failures: - 887b445bb878, 8th, 0 test.winehq.org failures, 13 here: https://testbot.winehq.org/JobDetails.pl?Key=21611 - bd332f53f2d7, 16th, 0 test.winehq.org failures, 13 here: https://testbot.winehq.org/JobDetails.pl?Key=21610 - 329dfee70c35, 22nd, 13 test.winehq.org failures, 13 here https://testbot.winehq.org/JobDetails.pl?Key=21609 My MinGW compiler is more recent than the one WineHQ was using before the upgrade however. So I think this points to a compiler-related issue. The official WineTest binaries are build on WineHQ so I suspect the MinGW upgrade is somehow responsible for the new failures. However I don't know if the old compiler was masking them, of if the new one is causing them. Any ideas? For reference: * Debian Testing (my environment): $ i686-w64-mingw32-gcc --version i686-w64-mingw32-gcc (GCC) 5.3.1 20160205 * Debian 7 (close to former WineHQ environment): $ i686-w64-mingw32-gcc --version i686-w64-mingw32-gcc (GCC) 4.9.1 -- Francois Gouget <fgouget(a)free.fr> http://fgouget.free.fr/ Nouvelle version : les anciens bogues ont été remplacés par de nouveaux.

WineConf 2016
by Michael Stefaniuc June 19, 2016

June 19, 2016

Hello guys, it's that time of the year again where we start thinking about the next WineConf. Last year would already have been the turn for North America so the next WineConf will happen definitely there. Jeremy White / CodeWeavers, as always, was very generous and offered to host it in Minneapolis (or was it St. Paul? ;). But if you're in US / Canada and really hoped to host the next WineConf now is your time to speak up! The Twin Cities are beautiful at -30 C but we wouldn't mind seeing other places too. bye michael

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

That applies somewhat to struct ps_compile_args as well, although we may care less there.

Could you maybe also add a couple of additional tests with charge_quota = TRUE? Since you are changing both versions, I'm fearing a bit that your changes could break other situations. If there are no unexpected test failures it looks good to me.

That second check can probably be improved by verifying that the constants fit into the CLIT comment instead (see below). BTW, the function return type is HRESULT, those returns generate warnings for me. > + pres->ins = HeapAlloc(GetProcessHeap(), HEAP_ZERO_MEMORY, sizeof(*pres->ins) * pres->ins_count); You should probably check this allocation too. > + for (i = 0; i < pres->ins_count; ++i) > + { > + unsigned int *ptr_next; > + > + ptr_next = parse_pres_ins(p, count, &pres->ins[i]); > + if (!ptr_next) > + return D3DXERR_INVALIDDATA; > + count -= ptr_next - p; > + p = ptr_next; > + } > + > + if (!count) > + { > + WARN("Byte code buffer ends unexpectedly.\n"); > + return D3DXERR_INVALIDDATA; > + } These kinds of size checks probably work but they are somewhat hard to follow. You could instead check the size of each comment section (making sure that it doesn't overflow the whole bytecode buffer) and then check that you don't go outside of each comment while parsing it. find_bytecode_comment() could do the first check before returning and, for example, also return the comment size so that the caller can use it to validate the relevant accesses. Hopefully what I mean is clear enough, otherwise as usual feel free to ask. > +err_out: > + FIXME("Error creating parameter evaluator.\n"); > + d3dx_free_param_eval(peval); > *peval_out = NULL; > - return E_NOTIMPL; > + return; > +} That return is now unnecessary.
