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

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? Generalliy what component should I switch while file a bug about IE crashing? Many thanks! -- Regards, Qian Hong - Sent from Ubuntu http://www.ubuntu.com/

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

`setupapi` patch from staging
by Donat Enikeev 24 Apr '17

24 Apr '17

Hi Guys, Number of recent well-known games are based on Starling game engine (Adobe Air+Stage3D for gpu rendering), such as: The Banner Saga 2, Samorost 3, The Inner World, Angry Birds. They are are falling into Software rendering mode on plain Wine and thus barely playable (bug #41635) Thanks to Béla Gyebrószki finding @ bug #41653, Wine makes these games consider d3d9 rendering with the following single patch from wine-staging https://github.com/wine-compholio/wine-staging/blob/master/patches/setupapi… This patch implements support of the case when a full driver path is passed to SetupDiGetClassDevs (trace successfully reaching AddDeviceToSet for a game below [1]). I was unable to find @wine-devel discussion around this patch, I would be grateful if one could kindly remind why it was staged, probably it just requires refactoring around the change or additional tests? I am asking this, because Adobe stopped Linux support for the Air years ago and we could never see such games ported, and therefore plain Wine's support of gpu acceleration for such games looks important. Thanks in advance Best regards, Donnie [1] 0009:trace:setupapi:SetupDiGetClassDevsExW {4d36e968-e325-11ce-bfc1-08002be10318} L"PCI\\VEN_0000&DEV_0000" (nil) 0x0000000a (nil) (null) (nil) 0009:warn:setupapi:SetupDiGetClassDevsExW unsupported flags 0000000a 0009:trace:setupapi:SetupDiCreateDeviceInfoListExW {4d36e968-e325-11ce-bfc1-08002be10318} (nil) (null) (nil) 0009:trace:setupapi:SETUPDI_EnumerateDevices 0x464ac90, {4d36e968-e325-11ce-bfc1-08002be10318}, L"PCI\\VEN_0000&DEV_0000", 0000000a 0009:trace:setupapi:SETUPDI_EnumerateMatchingDeviceInstances L"PCI" L"VEN_0000&DEV_0000" 0009:trace:setupapi:SETUPDI_AddDeviceToSet 0x464ac90, {4d36e968-e325-11ce-bfc1-08002be10318}, 0, L"PCI\\VEN_0000&DEV_0000\\13&12345&0", 0

Re: [PATCH] winealsa.drv: Fix handling of system real time MIDI messages

I also noticed Reset is still handled as a SysEx after your patch. Should it be? Aside from that, I also noticed an old patch that unfortunately never got merged: https://www.winehq.org/pipermail/wine-patches/2013-January/121366.html If you understand this MIDI stuff a little bit, you might be a good person to review and re-submit that patch :) Thanks, Andrew

We probably should just fail at CreateXmlWriterOutputWithEncodingName() and print encoding string that made it fail.
