Re: widl: Set name return value (passed by reference) in the alias case alias case in get_user_type.

It's initialized when we return a type, and it doesn't need to be initialized on NULL return. The code is correct, but you could probably set the variable to NULL in the caller to silence the warning. -- Alexandre Julliard julliard(a)winehq.org

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

COM tracing ...
by Michael Meeks Aug. 21, 2018

Aug. 21, 2018

Hi guys, Rather a peripheral question; apologies for that - but I'd imagine there are experts here that may be able to help. I have a black-box problem - a Windows app dealing with confidential data that I can't easily touch (and thus can't get to run under Wine) - which does some small but critical automation of MS Office - using VBS / COM scripting. I'd -really- love some input on how best to trace that series of COM method calls on Windows itself ie. the (remote) service activation, and the RPC beyond that - particularly the method names, parameters etc. of the COM/OLE Office API. I've tried (so far): http://www.rohitab.com/apimonitor which, while closed, looks interesting; but traces a lot in a hard-to-search way and doesn't appear to do the trick. https://support.microsoft.com/en-us/help/926098/how-to-enable-com-and-com-d… Sounds useful: using Event Tracing for Windows (ETW) but has this rather unhelpful property: "The binary file must be formatted by Microsoft so that it can be analyzed. Please forward the .etl files to your support contact. ..." ;-) Component models used to be all the rage in my youth ;-) surely someone solved the "strace for COM calls" problem elegantly some-when ! Crazily - might it be possible to instrument, interpose and use Wine's COM impl. on Windows [ which sounds a bit 'exciting' ;-], or ? Anyhow - help much appreciated & sorry for the noise ! Regards, Michael. -- michael.meeks(a)collabora.com <><, Pseudo Engineer, itinerant idiot

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

I also like this patch as logical next step, I'm just a bit worried because it locks out current builds without upgrading to an RC... At the moment I'm doing winelib builds with gcc for Linux/ARM64 and clang builds for Android/ARM64. It's quite easy on Linux to pick up a new clang version, not sure how long it takes until clang5 is picked up in the Android NDK... On the other hand, there are not much people building Wine for ARM64, and those can pretty easily revert your patch until they are at clang5 OK... We need this improvement, I'll sign it off :) Now, we only need to convince distributions to avoid x18

crash due to weird freetype font in gdiplus/sse
by Marcus Meissner Dec. 14, 2017

Dec. 14, 2017

Hi, we saw this during wineconf http://test.winehq.org/data/010119085b4cee3d7edbad2c5a46d35daa95000d/linux_… the actual instruction is: cvttsd2si $xmm0, $eax which receives a FPE trap as the content of $xmm0 does not fit into $eax. http://www.jaist.ac.jp/iscenter-new/mpc/altix/altixdata/opt/intel/vtune/doc… This means someone switched on FPE traps for XMM instructions in $CR4 register, which I would expect freetype2 the prime candidate if it is not Wine itself. Debugging shows that capEmHeight and capXHeight are both values < 0. long story short, in the loader we get these values: fixme:font:get_outline_text_metrics L"Goha-Tibeb Zemen" sCapHeight=-32768 fixme:font:get_outline_text_metrics L"Goha-Tibeb Zemen" sxHeight=-32768 The documentation does not give 0x8000 a specific meaning in the OS2 table. I can provide this font if needed for debugging. Ciao, Marcus
