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...

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

IMM / IME work
by Aric Stewart 16 Jun '16

16 Jun '16

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

DirectInput already has some internal abstraction layers for differnet joystick APIs, and has basic support for OSX joysticks. Does DInput have enough capabilities to access all the Xbox controller's features? My gut says no, otherwise MS wouldn't have created a new lib. I guess its worth checking though.

What happened to the Fedora packages?
by Neal Gompa 02 Aug '14

02 Aug '14

What happened to the Fedora packages? They have not been updated since 0.9.2!!!! Right now it is at 0.9.10!!! Nearly every other Linux distro supported has the up to date packages!!! And why does the Red Hat packages site not go to the SourceForge site as it does for SUSE packages and the others?? I have not really had the guts to ask until now, because I thought that maybe there was a slump, but now, its getting annoying!! And Fedora just released Fedora Core 5 yesterday!!! Please tell me new packages will be ready soon!!! Compiling WINE always crashes my computer, so I prefer to use the RPMs...

FOSDEM '14 Call for Papers
by Jeremy White 02 Dec '13

02 Dec '13

Folks, There will a Wine devroom at FOSDEM '14 on Sunday, February 2, 2014. Last year we had a great time, and I think it was valuable for us to connect with the broader Free software community. I'd like to now invite you to submit proposals for talks. I'd really like to encourage everyone to think of something fun to share with the 5,000 geeks that will be swarming Brussels. If you have an topic you'd like to discuss, or an idea you want to present, please submit it to: https://penta.fosdem.org/submission You will create an account (if you don't have one from a previous year), and select the "Wine devroom" as the track. Please either submit for lengths of 30 or 60 minutes. The deadline for submissions is December 1st. I think it would be great if we branched out a bit, and submitting a crazy off the wall proposal will just burn churn a few electrons. So submit it! For further discussion, please follow up to wineconf(a)winehq.org. Cheers, Jeremy

WineTestBot status update
by Francois Gouget 14 Nov '13

14 Nov '13

We switched to the new WineTestBot near the start of September. Early on it ran into a problem when it was flooded with tests due to the __WINESRC__ tests work and it failed to keep up. The reason is that as time went on the time it takes to get the VMs back to a clean state ready to run the tests (the revert time) kept increasing as can be seen on this graph: http://fgouget.free.fr/wtb/vm1-revtimes.png There one can see the increased activity in september that what was caused by the surge in test patches. But the most remarkable feature is the Windows XP revert times which increase linearly, reaching over 30 minutes. The revert times for the other VMs are much more random but still seem to increase somewhat (1). The reason for the increase is still unknown. The revert time fell down a few times and now I suspect this corresponds to times when the VM was restored from backup. So at the start of October I upgraded to QEMU 1.6.0 and restored all the VMs from backup, hoping this would solve the problem. The revert times did get much better and the WineTestBot now manages to keep up: http://fgouget.free.fr/wtb/vm1-revtimes-new.png The upgrade happened around the 2nd of october and the revert times fell at that point. But looking at more recent data it's clear that the Windows XP revert times are increasing again, while those of the other VMs remain stable (see vm1-revtimes.xls for the raw data). That XP VM is one of the first ones I created, so it probably was created with a pretty old QEMU version. Futhermore it was only an out of the box SP2 and did not have any of the later updates. So I decided to recreate it from scratch, using QEMU 1.6.0, and to add all the other updates as I was at it. And I'm hoping that this time things will be better. That's why this VM is currently in 'maintenance' mode. I also took down the 32-bit Windows 8 VM for maintenance. It too is missing proper updates and the plan is to upgrade it to Windows 8.1. Another issue has been that the tests are running a bit slow, a particular point of pain was msi:action and msi:install which were regularly timing out. See: http://fgouget.free.fr/wtb/runtimes.htm So while rebuilding the Windows XP VM I did some performance tests. That paid off. I found that switching the emulated disk cache mode from writeback to default roughly halves the msi run times: http://fgouget.free.fr/wtb/runtimes2.htm msi:action and msi:install went from an average of 99 and 90 seconds down to 48 and 39 seconds and they are not timing out anymore. The remaining troublesome tests are now ddraw:ddraw{2,4,7}, shell32:shlexec, and winspool.drv:info. I also uncovered two other potential performance issues: * Some VMs have Windows Defender and apparently it was starting a full disk scan as soon as the VM was ready to run the tests. That's clearly not good so I disabled Windows Defender in all VMs. * Most VMs were still using 20% of the CPU when idle. That's fine if only one VM is running but could impact performance (through increased interrupt rates) if many are running at once (like on the WineTestBot). Apparently the culprit is the USB Tablet device that's added by default. So I removed it from all VMs too (and now the mouse is even more laggy than before when I work on the VMs :-( But that does not impact the tests). So there is still a lot of work to do on the WineTestBot, and that's not even counting fixing all the failing tests. (1) It's almost as if the increasing Windows XP revert times were pulling up the other VM revert times. Yet there's only one revert at a given time, so I don't see how this would be possible. (2) Setting the cache mode to writeback was improving the performance quite a bit with the pre-upgrade QEMU version. But obviously it's not true anymore. Another interesting point is that the Virtio mode improves performance by a factor of 10 (down from 450 seconds to 45 in msi:action). Yet Windows 8 posts the fastest times yet in the basic IDE mode (~23 seconds). I couldn't get Windows 8 working with the Virtio disk yet and I have not verified that it's really doing the same set of tests. So that remains to be confirmed. Here is some performance data taken from the Windows XP VM while the TestBot was idle. From it cache=default looks like it's a completely separate mode! msi:action | msi:install | msi:msi 448 460 520| 487 439 | 238 229 VGA, qcow2 ide disk, cache:default 44 45 42 | 47 49 46 | 24 23 21 VGA, qcow2 virtio disk, cache:default 48 45 50 | 47 48 48 | 23 23 24 VMVGA/VGA, qcow2 virtio disk, cache:default 47 46 | 48 46 | 23 22 22 VMVGA, qcow2 virtio disk, cache:default 47 47 | 49 48 | 24 23 VMVGA, raw virtio disk, cache:default 62 67 67 | 64 60 63 | 29 27 27 VMVGA, raw virtio disk, cache:none 111 92 72 113 | 101 101 | 37 37 40 VMVGA, raw virtio disk, cache:writethrough 61 64 53 | 70 59 58 | 36 28 29 VMVGA, raw virtio disk, cache:writeback 46 44 | | VMVGA, raw virtio disk, cache:default 71 55 68 | | VMVGA, raw virtio disk, cache:writeback 65 71 72 69| | VMVGA, raw virtio disk, cache:none 76 118 111 | | VMVGA, raw virtio disk, cache:writethrough 50 48 47 | | VMVGA, raw virtio disk, cache:default And the preliminary Windows 8 performance.
