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

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

I'd personally argue that checking and forcing indentation rules by a C compiler is pretty disappointing and actually misleading. That warning should be turned off by default IMHO. -- Dmitry.

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

Student interested in GSoC 2016 implementing D3DX9 API idea
by Xu Zhao March 22, 2016

March 22, 2016

Hello Wine Community, First congrats that Wine Project get accepted into GSoC 2016 summer organization! I am currently a PhD student in University of Toronto and I am interested in the D3DX9 API implementation task. Mainly because I would like to see more games can run in wine because of my work! My research field is operating system so I am a pretty good C/CPP programmer. However I am not very familiar with DirectX related programming and hopefully I can get some help from the community, like where to start. I have read the wiki entry of D3DX9 API and want to get some help in selecting a reasonable sized API list, maybe someone can reply and provide some help? Thank you!

GSoC Idea: Tools - Winetest Scripting Interface
by Zhenbo Li March 15, 2016

March 15, 2016

Hello, I'm Zhenbo Li. I participated in GSoC twice. This year, I want to work on "Tools - Winetest Scripting Interface". After "make test", checking the output in stdout manually is horrible. As ok() macro is used quite widely, my patches should cause no surprise. That is to say, other developers need to read neither my patches nor the changelog to continue their jobs, although ok() macro and other tools for test have been changed. I think there will be two steps for the goal: 1. ok() macro ===================== int winetest_vok( int condition, const char *msg, __winetest_va_list args ) { tls_data* data=get_tls_data(); if (data->todo_level){...} else { if (!condition) { printf( "%s:%d: Test failed: ", data->current_file, data->current_line ); vprintf(msg, args); InterlockedIncrement(&failures); return 0; } else{.....} } } Instead of printing all the data to stderr, I think we can write a wrapper static void test_print(const char *s) { if(want_print_to_file) fprintf(file_handle, s); printf(s); } It needs some work to make sure that the file_handle is opened/closed successfully. With that, we can record the failed tests to a file, and developers don't need to find them in stdout anymore. 2. compare the results ======================= On the idea page, it says that any scripting language is acceptable. I prefer Python3. To make the code simple, I think editing runtest script is the best solution. Currently, our logic in Makefile is htmllocation.ok: ../../../tools/runtest $(RUNTESTFLAGS) -T ../../.. -M mshtml.dll -p mshtml_test.exe.so htmllocation && touch $@ And in runtest, we have exec $WINETEST_WRAPPER "$topobjdir/wine" "$program" "$@" I don't want to touch Makefile. Instead, I'm going to add some options for runtest. For example, one can use ../../../tools/runtest $(RUNTESTFLAGS) -new_option expected_errors_generated before -T ../../.. -M mshtml.dll -p mshtml_test.exe.so htmllocation And in runtest script, we can expected_errors_generated and new_errors_got, then tell that whether the test result has been changed. It should be easy for developers to write a script for git bisect or other circumstance. Problems ========= This approach seems to be quite simple, and there are some conditions can't be handled. For example void test_foo(sturct Data *d){ ret = foo(d); ok(ret, "foo(%s) is %d\n", data_to_str(d), ret); } struct Data list[]={a,b,c,d,e}; void test(){ for(i in list) test_foo(i); } I think we should not do too much "smart deduce" here, and don't hide what's happening to other developers. Maybe we can add another option for runtest script: --scrict=false This is my humble idea for Wine's GSoC 2016. If this project goes well, working on wine test suit will be much more satisfying(although still boring). I appreciate for your comment. With you a happy weekend. -- Have a nice day! Zhenbo Li

Also it would be really nice to send the tests first so it would be more clear when a todo_wine is removed with a subsequent patch in order to see whether the patch is actually related to the previously sent tests. -- Dmitry.
