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...

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?

Wine's forked version of fontforge
by Jens Reyer Aug. 1, 2016

Aug. 1, 2016

Hi, in Debian we're currently moving to enable the maintainer mode to e.g. rebuild Wine's TrueType fonts. AJ already warned us that this is risky: On 04/01/2016 04:54 AM, wine-bugs(a)winehq.org wrote: > https://bugs.winehq.org/show_bug.cgi?id=40391 > > --- Comment #3 from Alexandre Julliard <julliard(a)winehq.org> --- > There is definitely a risk too, particularly for fonts. They are supposed to be > built with our forked version of fontforge > (https://source.winehq.org/git/fontforge.git) that contains a couple of fixes > compared to the upstream version. I really appreciate that warning, thanks again! See a "short" explanation at the end of the mail, why we want to do this anyway. I'd like to figure out how to improve the resulting situation by getting the Wine changes to fontforge applied upstream (and/or in Debian). With "upstream" I mean github.com/fontforge. I will contact them in a later step. Wine and Debian are both using the quite old fontforge version 20120731-b, the patches apply cleanly in Debian. But upstream is actively developing and in Debian someone is working on packaging a recent version (not sure with what outcome, e.g. afaik there is at least one upstream regression blocking an update). Are there any plans in Wine to update to a newer version? Wine's fontforge has 4 changes. I recreated them based on AJ's merge for 20120731-b and by myself for 20160404 to get a *rough* picture of their current state (not tested and I'm absolutely no expert in this): 1. Various hacks to avoid putting timestamps in generated files (AJ). No relevant changes upstream, but there is some work going to allow one to specify the timestamp in order to get the build deterministic/reproducible. Would this make this patch obsolete? I don't know why upstream wants timestamps at all, nor what problems these cause for Wine. Is this Wine specific, or would it make sense to drop timestamping upstream, too? 2. - Avoid outputting trailing spaces in sfd files (AJ). About a third seems to be applied in 20160404. I assume the rest would still be relevant if Wine updated its fontforge version. Is this patch only relevant for creating fonts/glyphs, but not for building the TrueType fonts? Looks like a good candidate for forwarding to upstream. 3. Enable the width of individual bitmap strikes to be altered (Huw Davies). Since the import of upstream version 20120731-b this patch only has a third of its original size. Are the remaining Wine changes still necessary, or are they cruft? If still needed, I guess they should be pushed upstream. In 20160404 not much seems to have changed, but the containing file bitmapview.c was moved ("splitting ui code from fontforge/ to fontforgeexe/"). Same as above: is this only needed when creating fonts? Looks like a candidate for upstream. 4. Don't save the selected state. (Huw Davies) I found no relevant changes upstream. No idea about this. Why are we doing this? ---------------------- The Debian Free Software Guidelines [DFSG] (which are the fundamental basis for the Debian project) mandate that binaries must be accompanied by their source (which is usually ensured by building from source), and that you must be able to modify and redistribute the package with only the software available in Debian. The reasons for these are e.g. philosophical (empowering the user), QA (rebuilding if there was an issue in the build tools), reproducibility (recreate byte-by-byte-identically, e.g. to rule out attacks at a build machine or do QA) or security (a build from correct source code may be manipulated by specific compilers). The TrueType fonts are pre-built with a forked fontforge, which isn't (and very unlikely will ever be) in Debian. To package the pre-built fonts imo we would have to remove Wine from official Debian (main), and move it to the non/semi-official contrib section. For the same reason (AFAIK, I'm not the author of these changes) we're also regenerating opengl files, request code and unicode. This problem was ignored/missed in the past for the Debian Wine packages, yet this is no argument against fixing them now. We definitely don't want Wine removed from Debian, instead keep it in and get it there as good as possible. btw, we're also adding a patch (based on wine staging) to append '(Debian)' to the version string now. btw2, can you recommend some alternative free fonts to install (either as partial replacement or as extension to the Wine fonts)? Greets, and thanks in advance jre [DFSG] https://www.debian.org/doc/debian-policy/ch-archive.html#s-dfsg, see also the following chapter "The main archive area".

Re: [PATCH v2] kernel32: Use setprogname(3) to set the program name if available.
by Theodore Dubois July 11, 2016

July 11, 2016

This patch causes a segfault in the event that __wine_main_argv is not the argv that got passed to main. This happened in a program I wrote that acts as a custom wine loader. It creates an argv by using malloc, then passes that to wine_init. Why wouldn’t setprogname(argv[1]) be adequate? ~Theodore > On Feb 19, 2016, at 2:33 PM, Charles Davis <cdavis5x(a)gmail.com> wrote: > > Signed-off-by: Charles Davis <cdavis5x(a)gmail.com> > --- > Try 2: > * Clean up the #ifdefs a bit.

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

Broken AppDB Test Results Pages
by Jimi Huotari June 1, 2016

June 1, 2016

Greetings! I sent two mails about this to appdb(a)winehq.org the other day, but austin987 suggested I'll mail here (and Cc jnewman), too, since it has been a few days now. So I broke a couple of pages: //appdb.winehq.org/objectManager.php?sClass=version&iId=24670 //appdb.winehq.org/objectManager.php?sClass=version&iId=24695 Using QupZilla (QtWebEngine edition), the Xinha editor took its built-in ad-block rules, with some of the style code, and included them in the code for the page, which breaks most of it (none of the test results or notes/comments\bugs show up). Loading up the form at AppDB resulted into a count of HTML: 259501, and this number goes up by about the same amount every time the form is reloaded, and (probably) all of it will be included in the code. It would be great if someone with the power to do so could undo my edits to the two pages I mentioned, as I can't do anything about it myself. :] I already reported the issue upstream of QupZilla, and a fix was quickly put in place there, but the editor itself remains vulnerable (no idea how big of an annoyance /really/ exploiting it could become). Thank you, and apologies for the inconvenience!
