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

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

Re: [2/2 v2] winex11: Use XIAllDevices to select for XI_RawMotion

The main consideration has to do with the way address space is allocated for Win32 applications, effectively making malloc() space a bit more scarce than HeapAlloc() space. We'd probably prefer the sizeof as "sizeof(*thread_data->x_rel_valuator)", or perhaps "sizeof(*class)". I'm not sure how much we should worry about this in practice, but when multiple slaves are attached to the master, and they're not completely idle, update_relative_valuators() can end up getting called quite a bit. It doesn't seem hard to at least do the allocation only once, and only update the data in update_relative_valuators(). Perhaps it's also fine the way it is though. > - XISetMask( mask_bits, XI_ButtonPress ); This was added intentionally (see also https://bugs.winehq.org/show_bug.cgi?id=27522#c18) Perhaps it's no longer needed, but that would need to be a separate patch. > + pointer_info = pXIQueryDevice( data->display, data->xi2_core_pointer, &count ); > + update_relative_valuators( pointer_info->classes, pointer_info->num_classes ); > + pXIFreeDeviceInfo( pointer_info ); ... > + pXISelectEvents( data->display, DefaultRootWindow( data->display ), &mask, 1 ); I'm not too concerned about it, but can this race? I.e. switching slaves between when update_relative_valuators() is called above and when XISelectEvents() takes effect. Applies to querying the devices list as well. > + if (thread_data->xi2_current_slave == 0) We'd typically write that "if (!thread_data->xi2_current_slave)", although I don't think anyone would be overly concerned about it. > + for (i = 0; i <= max ( x_rel->number, y_rel->number ); i++) > + { > +»······if (!XIMaskIsSet( event->valuators.mask, i )) continue; > +»······val = *values++; > +»······if (i == x_rel->number) > +»······{ > + input.u.mi.dx = dx = val; > +»······ if (x_rel->min < x_rel->max) > + input.u.mi.dx = val * (virtual_rect.right - virtual_rect.left) > + / (x_rel->max - x_rel->min); > +»······} > +»······if (i == y_rel->number) > +»······{ > +»······ input.u.mi.dy = dy = val; > +»······ if (y_rel->min < y_rel->max) You're using tabs for indentation here.

WineTest reference Linux machines
by Francois Gouget 09 Dec '16

09 Dec '16

CodeWeavers has two machines that I have been running WineTest on, in Linux, Windows 8.1 and Windows 10, in 32 and 64 bit. They are identical except for the graphics cards: AMD HD6800 for cw1 and Nvidia GTX560 for cw2. During WineConf we decided that these should be able to run WineTest on Linux without any errors and thus become reference WineTest machines. We are not quite there yet so here is the current status starting with the 32 bit tests. * crypt32:chain Some of the certificates used by this test are present on Windows but missing on Linux, thus causing the error. Hans is looking into it and either the test will be modified to use other certificates present on both platforms, or the certificates will be added to these boxes. In the latter case this will be documented on the Wiki: https://wiki.winehq.org/Conformance_Tests#Running_WineTest_in_Wine * d2d1:d2d1, d3d10core:device These tests only fails on the GTX560. The reason is unknown. We need someone to look into it. * d3d8:device, d3d9:d3d9ex, d3d9:device, d3d9:visual Matteo fixed the radeon driver configuration and is looking into these failures, at least for the HD6800 case. It is possible some of these failures are caused by the window manager (currently xfwm from Xfce). Replacing the windows manager is no issue, we just need to know which one to pick. fvwm2? * kernel32:console, kernel32:process These failures happen because the tests are being run from cron, with their output redirected to a log file and thus they have no real terminal to work with. Interestingly the 64 bit tests are not failing. Vincent is investigating whether the tests should be modified or whether the test should be run from an xterm, screen session or some equivalent. * user32:winstation winstation.c:959: Test succeeded inside todo block: unexpected foreground window (nil) The cause for this failure has not been identified. Another window manager issue? * ws2_32:sock sock.c:2811: Test succeeded inside todo block: Test[2]: expected 0, got 0 We need someone to investigate this failure. It looks like it's random and relatively rare. Some tests just cannot be made to work reliably on Linux due to the asynchronous nature of X11 messaging. So another decision that was made that tests should be run up to 3 times until they succeed. It's not entirely clear if that applies to all tests or just to specific tests that are known to be flaky. The practical upshot is that people running 'make test' can re-run it a couple of times if it fails at first, and if it succeeds after 3 tries then you can consider that it's all good. These machines run WineTest so the results can be uploaded to test.winehq.org (with the relevant header describing the machine, the dlls, etc). So WineTest may need to be updated to deal with flaky tests according to policy. Here is more detail about these machines: * i7-2600K (4 cores+hyperthreading at 3.4GHz) * 16 GB of RAM * 768 GB of spinning disk * Debian 8.2 64 bit * cw1: AMD HD6800 running the open-source radeon driver. * cw2: Nvidia GTX560 running the proprietary driver. -- Francois Gouget <fgouget(a)codeweavers.com>

Serial port sniffing problem
by Bill Lionheart 06 Dec '16

06 Dec '16

Using Wine version 1.8 on Ubuntu 14.04.5 I'm trying to use a AVRT5 APRS amateur radio GPRS tracker which has a serial interface. The device is supplied with a Prolific USB serial converter which comes up as /dev/ttyUSB0 which I have sym linked to COM1 The bundled GPRS tracker config software installs and runs OK under Wine. But my attempts to sniff the serial port traffic fails using all the standard Linux methods I know. I also tried using the Windows program Serial Port Monitor under Wine http://www.eltima.com/products/serial-port-monitor/ . This program says it cannot detect any serial ports. Under Windows 7 the config program and Serial Port Monitor both work well and I can intercept all the serial traffic Any ideas please folks? Bill
