Is it normal that the COM vtbl structure cannot be aligned between Windows and Wine
by zhengxianwei 11 Jun '25

11 Jun '25

In wine, Visual2Vtbl ``` typedef struct IDCompositionVisual2Vtbl { BEGIN_INTERFACE /*** IUnknown methods ***/ HRESULT (STDMETHODCALLTYPE *QueryInterface)( IDCompositionVisual2 *This, REFIID riid, void **ppvObject); ULONG (STDMETHODCALLTYPE *AddRef)( IDCompositionVisual2 *This); ULONG (STDMETHODCALLTYPE *Release)( IDCompositionVisual2 *This); /*** IDCompositionVisual methods ***/ HRESULT (STDMETHODCALLTYPE *SetOffsetX)( IDCompositionVisual2 *This, float offset_x); HRESULT (STDMETHODCALLTYPE *SetOffsetXAnimation)( IDCompositionVisual2 *This, IDCompositionAnimation *animation); HRESULT (STDMETHODCALLTYPE *SetOffsetY)( IDCompositionVisual2 *This, float offset_y); ``` setOffsetX (float *) at offset 0x18 [image: visual2vtbl.png] But in windows 0x18 is setOffsetX (Animation *) Is this correct?

Mismatch Between win32syscalls.h and Windows System Call Numbers
by zhengxianwei 05 Jun '25

05 Jun '25

The APIs and call numbers in win32syscalls.h don't seem to match those in the Windows system. NtGdiAlphaBlend is listed as 4 in win32syscalls.h, but in reality, it's 0x1075 in win32u.dll on Windows 11. So are these values user-defined?

How to implement
by zhengxianwei 03 Jun '25

03 Jun '25

Hello, I would like to implement part of the logic within dcomp.dll in order to properly support applications that depend on it. I found that Zhiyi Zhang has implemented some data structures and interface stubs: https://gitlab.winehq.org/zhiyi/wine/-/commits/directcomposition?ref_type=h… Among these, the only method with actual logic appears to be IDCompositionDevice::Commit. However, after reviewing the implementation, I suspect there may be an issue with the current approach. It seems that Zhiyi Zhang starts a separate thread for each IDCompositionDevice, and this thread runs at a fixed refresh rate. But this approach appears to introduce a problem: from the window's (HWND) perspective, there are now *two threads* concurrently updating its device context. This results in a frame sequence similar to the following (note: the frame intervals are illustrative only): gdi_frame | dcomp_frame | gdi_frame | gdi_frame | dcomp_frame In this model, GDI-generated frames and DComp-generated frames are interleaved. Is my understanding correct? If so, I believe this method may lead to *inaccurate rendering results*, although I am not entirely certain about the exact consequences (as I am not an expert in this area). Therefore, I have decided to pursue an approach that produces a *standardized frame stream* like the following: gdi_mix_dcomp_frame | gdi_mix_dcomp_frame | gdi_mix_dcomp_frame In other words, I plan to merge GDI and DComp content before presenting each frame, ensuring consistency in the final output. I’ve reviewed the normal GDI frame refresh process, and it seems to follow this path: --> flush_window_surfaces --> window_surface_flush --> x11drv_surface_flush I’m planning to insert the following logic inside x11drv_surface_flush: if (is_hwnd_bind_to_dcomp(hwnd)) { struct Surface *final = get_comp_surface(hwnd); blend_dcomp_surface_over_gdi(dest_surface, final); } However, there’s still a question regarding *how to access the DComp data* inside x11drv_surface_flush. One option is to do the composition inside IDCompositionDevice::Commit() like this: void IDCompositionDevice_Commit() { composite_proc(); ... ... push_frame_to_x11drv(); } Another option is to *directly call into DComp APIs from within x11drv* to retrieve the surface data on demand. However, *both approaches feel somewhat unnatural*, and from what I can tell, Windows seems to establish some kind of *internal channel* to pass the composed content to the compositor. Is there a better or more canonical way to do this? Any suggestions or guidance would be greatly appreciated.

IRandomAccessStream doesn't belong in windows.storage
by light gray 21 May '25

21 May '25

Hi devs! I've recently noticed that there's a new `windows.storage` WinRT library within Wine, and the library houses a stubbed implementation for `IRandomAccessStream`. There's an issue however. Looking at Windows registry keys to see which libraries register which runtime classes, it appears `shcore` houses the implementation for `IRandomAccessStream`. Not `windows.storage`. While inherently this isn't a problem since applications acquire runtime classes via `RoGetActivationFactory`, this could pose an issue later down the line when more WinRT interfaces get implemented within Wine. Mainly with how different classes are registered at compile time. Not only that, it would also make implementing functions such as `CreateRandomAccessStreamOnFile` a bit more complicated. As a reference, the following is my own experimental implementation of `IRandomAccessStream`: https://github.com/Weather-OS/WineCoreUAP/commit/318d3b8ecb036f04dcf6365235… Best wishes, Weather.

How to use AddressSanitizer with Wine?
by Alex Henrie 18 May '25

18 May '25

Dear oenologists, I would like to use GCC's AddressSanitizer [1] to investigate a memory corruption bug in Wine. There must be a way to do it because I see multiple references to "ASan" in the Wine commit log in commits from this year.[2] I found some instructions on the WineHQ wiki,[3] but I get a myriad of linker errors when I try to follow them. What Linux distributions can successfully compile Wine with libasan? Are there special steps not mentioned in the wiki? Does AddressSanitizer work with MinGW, or only with non-PE builds? I'd love to get AddressSanitizer working myself, but even if I can't, thanks to Bernhard and Nikolay for using it to fix a lot of bugs already. -Alex [1] https://github.com/google/sanitizers/wiki/AddressSanitizer [2] https://gitlab.winehq.org/wine/wine/-/commits/master?search=ASan [3] https://gitlab.winehq.org/wine/wine/-/wikis/Building-Wine#memory--address-c…

How to add multiple versions of the same DLL (with the same base name) in apisetschema.spec?
by zhengxianwei 18 May '25

18 May '25

Hello, I'm planning to add the following line to apisetschema.spec: *api-ms-win-power-setting-l1-1-1 = powrprof.dll* However, this causes a hash conflict with the existing line: *apiset api-ms-win-power-setting-l1-1-0 = powrprof.dll* May I ask how you usually resolve such conflicts? I'm concerned that removing version 1-0 might cause some older applications to stop working. Would it be possible to delete the router for 1-0 and instead add a new line like this? *ln -s powrprof.dll api-ms-win-power-setting-l1-1-0*

Pre-commit
by robert lippmann 16 May '25

16 May '25

Hi all, I was looking in the docs, and came across this (https://gitlab.winehq.org/wine/wine/-/wikis/Git-Wine-Tutorial#removing-trai…): "It fixes whitespace on all the commits that you've made. I think it's pretty good about merge conflicts due to whitespace as well. I don't know of a way of doing this at commit time though.” Well, actually there is. Pre-commit (https://pre-commit.com/). Actually fixing whitespace is a built in rule, I believe. And there are various others tailored to different languages. It’s used pretty extensively in Python development, but doesn’t need Python. Since it runs in node, there’s a VSCode extension for it. So, I was wondering if there was any interest in perhaps adding the yaml configurations to the wine source tree, and figuring out what rules might be useful to implement. Thanks, Rob

16 May '25

Hi all, I submitted a patch, and needed to make changes. I made the changes, but am not sure how to submit it for re-review. I’m used to GitHub, and less formal development practices where it just automatically pops up as open again. Is there something I need to do to get it so it’s mergeable again? I’ve been rebasing for weeks. Should I just close the MR, and submit a new one? Thanks, Rob

[RFC] Running Wine under AddressSanitizer
by Yuxuan Shui 13 May '25

13 May '25

Hi all, I've been working on this for a while and the list of changes are getting long. So I think this is a good time as ever to announce it, and get some feedback to make sure I haven't gone too far off the rails. This email is a bit long. What is this about? =================== AddressSanitizer (ASan for short) is one of a class of tools that help with discovering common coding mistakes. ASan specifically detects memory problems, like buffer overflows, use after frees, memory leaks, etc. It has been extremely successful in the past decade, and the list of bugs it helped discover is very very long. It has even already seen successes in the wine project as well. @bernhardu was able to get the PE side of wine to work with ASan (with some exceptions) using llvm-mingw, after he fixed [1] a handful of incompatibility problems in llvm compiler-rt. And with that many bugs [2] were then discovered and fixed. And my plan is to take this a step further. [1]: https://github.com/llvm/llvm-project/pulls?q=is%3Apr+is%3Aclosed+author%3Ab… [2]: https://gitlab.winehq.org/bernhardu/wine/-/blob/asan-pe_2025-04-26_wine-10.… Goals ===== I want this to be a quick and easy to use tool, the first thing one would reach for when seeing something that might be a memory related problem. e.g. I spend 5 minutes reproducing the bug with an ASan-enabled wine build, if it catches it, then I am done; otherwise I move on with my usual debugging routine, without having wasted too much time. I also want it to be a first line of defence, which runs in CI to catch occasional bugs that slip through reviews. In my mind, this means 1) it must be easy to set up, ideally just a flag passed to `configure`, no fuss. 2) it should cover as much of wine as possible, both PE and unix, and ideally all PE DLLs. Current status ============== Wine builds and runs. A majority of test cases pass, but some failures seem to be ASan related, which I still need to investigate. Both stack and heap problems are detected and reported. Stack traces are captured, but only on the PE side, and are not symbolized yet - I need to pipe the numbers into llvm-symbolizer. Stack traces aren't being saved for heap allocations and frees, so for use-after-frees the reports aren't very useful yet. Fiber support is TODO. Leak detection is TODO as well. Works done so far ================ You can find my branch here: [3]. To build it, you need either clang, or a slightly patched [4] gcc, and you just run configure with `--enable-sanitize`. I tried to put into the commit messages as comprehensive a list of what I did as possible, but I'll also provide an overview here. It's very abbreviated to not make this email even longer. If you need to know of how ASan works, there is a quick explanation here [5]. Since no existing ASan runtimes can support the unix and the PE side at the same time, I chose to write my own ASan runtime. The runtime is made part of ntdll, since that's the first DLL that loads. A non-standard shadow offset was chosen, so in the new WoW64 mode the 32-bit and the 64-bit side can share a common shadow. Shadow memory is mapped very early inside `virtual_init` to make sure we can enable ASan for as much code as possible (though doing it inside the loader is also an option). Some care needed to be taken to make sure no false positives show up after stack manipulations (e.g. unwinding). Redzoning and quarantining is added to ntdll's heap allocator, though I don't like that. [3]: https://gitlab.winehq.org/yshui/wine/-/commits/address-sanitizer-presentable [4]: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=119926 [5]: https://github.com/google/sanitizers/wiki/AddressSanitizerAlgorithm Request for help ================ I intend to continue working on this, and I don't really see any technical challenges that would make this fundamentally undoable. But I do worry that certain things I had/will have to do might make this not upstreamable. So, I think I need some guidance. (I will open a draft MR on winehq gitlab shortly, if you prefer commenting there). Bad things I did to get it working ---------------------------------- There are certain things I did that didn't feel good when I did them, so I am listing them here to see if anyone has a better way to do them. - ASan runtime as part of ntdll. I can't think of a better place to put it, since the runtime needs to be available before PE code runs. This also means all these functions are exported from ntdll, and I have yet to find a way to not export them when ASan is disabled. - dinput/tests and ntoskrnl.exe/tests need to be linked with ntdll, since they need to get their ASan runtime from ntdll. - Things I added to winecrt0. ASan uses some global variables for information such as where the shadow was mapped, and dynamically linked libraries need this information too. On the unix side the dynamic linker will nicely find them for you, but the same doesn't work with PE. So ASan duplicates these variables for each DLLs. In the vanilla ASan runtime, this comes from linking with a "dynamic runtime thunk"; in wine, I felt winecrt0 is the best place for them? These variables also need to be initialized, which means calling an ASan interface function which is exported from ntdll, from `DllMainCRTStartup`. This meant I had to add `-Wl,--{start,end}-group` for starters, because now libntdll.a and libwinecrt0.a have circular dependencies. Additionally though this works for other DLLs, it becomes a problem when winecrt0 is linked into ntdll, which creates a importing-from-self situation. I added a `DllMainCRTStartup` to ntdll, so the one from libwinecrt0.a is not pulled in, thus breaking the cycle. But it definitely feels wrong. (Vanilla ASan does this initialization by putting functions into the `.CRT$XIB` section, which the CRT will call on DLL load. I was told wine CRT doesn't implement this). - `__WINE_FRAME`. I don't fully understand this, but IIUC this is a hacky exception/unwinding mechanism, for when the compiler doesn't support native __try/__except? These are put on the stack which later the unwinder will look for to find the correct exception handler. This doesn't work since ASan uses fake stack frames, so the unwinder can't find these `__WINE_FRAME`s and thus fails. I get this somewhat working by translating between fake and real stack addresses, ew. I don't know much about SEH, is it really not possible to use it for these __try/__excepts as well? Things I need advices on ----------------------- - Heap. I added ASan redzoning directly to the ntdll heap allocator, which I don't like since it added a lot of complexity to it, and it's not available on the unix side. I want to write an ASan specific allocator, since performance and memory efficiency aren't major concerns here, this allocator can be made simple. But I am not 100% sure if this is a good idea. - Stack trace. What's the best way of capturing stack traces from PE _and_ unix, if we are in a syscall/unix call for example? - Shadow offset. This is a bit complicated. clang supports dynamic shadow offset but mingw-gcc doesn't (it doesn't officially have ASan support), so for max compatibility we want a fixed shadow offset. If we want a single shadow to be shared between 32 and 64 bit in the case of new WoW64, the shadow offset needs to be below 4G, which basically precludes non-relocatable 64-bit PE from being loaded (the shadow takes 16 TiB); or we choose a high shadow offset for 64-bit to avoid conflicts, but that means we need to mirror this shadow into the lower 4G of the address space for 32-bit, which complicates the initialization phase. (If you made it to the end, thank you!) -- Regards Yuxuan Shui

How do I determine which functions are unimplemented?
by zhengxianwei 07 May '25

07 May '25

When a function is commented out and the application calls it, the application crash silently . I dont know which function caused this. Is there any way to quickly determine which functions are unimplemented ? eg: https://github.com/wine-mirror/wine/blob/226a7eeabbc13345e49da1ff8c018d6f06…

Why, in Wine, are some unimplemented APIs not marked as stubs but instead commented out?
by zhengxianwei 06 May '25

06 May '25

This results in a situation where, due to the missing API, the program doesn't report an error but instead directly aborts; whereas if it were marked as a stub, it would produce a clear error eg: https://github.com/wine-mirror/wine/blob/226a7eeabbc13345e49da1ff8c018d6f06… Does this involve some of wine's development philosophy?

Announcing WineConf 2025
by Alexandre Julliard 24 Apr '25

24 Apr '25

Folks, It's been a while, so it's time for another WineConf! Given that a large proportion of the Wine devs are working for CodeWeavers, we thought that we'd do WineConf right after our annual company meeting, to take advantage of most people being in town already. So the plan is to hold WineConf on Saturday September 27, 2025. The location is The Hague, Netherlands. In fact it will be the exact same venue as WineConf 2018, which I'm sure many of you remember fondly ;-) You can find all the details here: https://gitlab.winehq.org/wine/wine/-/wikis/WineConf/WineConf-2025 Please note that we ask people to register so that we can get a headcount for the hotel. Attending is free of charge, and travel sponsorship is available. Looking forward to seeing many of you there! -- Alexandre Julliard julliard(a)winehq.org

Upcoming vkd3d 1.16 release
by Henri Verbeet 15 Apr '25

15 Apr '25

Hi all, The planned release date for vkd3d 1.16 is May 20. That means the public API will become frozen a week from now on April 22, and features will be frozen two weeks before the release, on May 6. This (of course) does not mean that development should slow down or stop; after making sure that we're in good shape to release, this would be the ideal time to make sure any larger features are ready to get merged at the start of the next development cycle. As usual, if you're an upstream vkd3d developer, please do the following: - Keep an eye on Bugzilla for any reported regressions. - Review any API changes since the previous release. - Verify that all vkd3d tests pass on your hardware/setup, and please send fixes if they don't. - Review and improve the documentation. - Get any larger features ready to get merged at the start of the next development cycle. If you're a downstream user of vkd3d, please test your applications for any regressions, and file bug reports if you find any. The planned release date for vkd3d 1.17 is August 21. Regards, Henri

Apple Silicon compilation
by robert lippmann 10 Apr '25

10 Apr '25

Hi all, I tried to update the wiki to document how to compile Wine on Apple Silicon, but I’m not sure if it went through. Basically, you need to add lld (which pulls in llvm) in addition to the other build dependencies So: brew install lld Then: PATH=`brew —prefix llvm`/bin:`brew —prefix bison`/bin:$PATH Then everything compiles. You probably don’t even need Xcode. And you probably should have Rosetta2 installed. I haven’t actually been able to get it to run yet, though… — Rob

Wine with 64 bit prefix and databases
by Ilya Sokolov 04 Apr '25

04 Apr '25

Hello It may be not the best place to send the question to this list, but I have tried it on different forums and got no answer. I have a windows C++ application, which should be run in x64 environment due to a memory consumption. One of users of the application requires it run on Linux. The application is rather big and uses some windows-specific features, like COM interfaces, so it would be hard to make it cross-platform. Therefore it was decided to try running the application under Wine. The application uses an MS Access database , which contains some parameters and settings for calculations. The application successfully runs under WINE until it tries to connect to the database, because there is no ADO data provider available. I have tried installing MDAC via winetricks, downloading and installing Access Runtime 2010 and 2016, but all with ho success. Could you tell me what is the proper way of setting up the access ADO driver in WINE in x64? If it is not possible now, could you tell me if any database works on wine in 64 bit prefix, so I will change the database type in the application. Thank you! Best Regards, Ilia Sokolov

Troubleshooting openSUSE's packaging process
by Alexander Leithner 03 Apr '25

03 Apr '25

Hi all, back in October [1] I asked for advice on building Winelib DLLs because I was unable to compile 64-bit DLLs on my openSUSE Tumbleweed machine. I've since opened bug 1231820 [2] on openSUSE's Bugzilla that has yet to be resolved (which I understand, given that developing Wine-only applications is pretty niche, I reckon). While I can now (with Wine 10.0 from openSUSE's repositories) compile 32-bit Winelib DLLs without having to explicitly specify the library search path, 64-bit DLLs still don't work. This is because the packages are missing the relevant archive files (*.a) for 64-bit ELF; that is, all the libraries (*.so) are present in /usr/lib64/wine/x86_64-unix, but the corresponding *.a files are not. I was trying to troubleshoot this earlier today but I'm now lost (since I cannot, for the life of me, reproduce the build process behaviour) and would be grateful for any discussion of what I might be misunderstanding/doing wrong or what might be going wrong with the packaging process. The first noteworthy observation is that the RPM spec file [3, see lines 367-449] excludes all archive files when the package built is not the "-devel" variant, which is fine, but only includes the i386-unix archives when "-devel" is built. That is probably an oversight, but not the main problem, I reckon. Namely: The x86_64-unix *.a files do not show up in the build logs [4] at all (Ctrl-F for "unix/libwinecrt0.a", for example). Even more, RPM itself complains that the files it should exclude are not found when building the non-devel variant of the package (Ctrl-F for "not found", messages around the 999s mark). This, to me, indicates that the files aren't even built. As can be seen in the logs, openSUSE uses the following ./configure command line to build 64-bit Wine: ../configure --host=x86_64-suse-linux --build=x86_64-suse-linux --program-prefix= [...] --with-x --with-wayland --with-gstreamer --enable-win64 --verbose (I've omitted prefix- and dir-related switches). I've built Wine from source with the following command line: ../configure [...] --build=x86_64-suse-linux --build=x86_64-suse-linux --enable-win64 (I've omitted --prefix only here). This produces an environment which can correctly build both 32-bit as well as 64-bit Winelib DLLs (without needing to set -L explicitly, as expected). I can see install-sh calls, as expected, for the *.a files in lib64/x86_64-unix, which are absent from the OBS build logs. My commandline generates lib64/x86_64-unix and lib64/x86_64-windows. On the other hand, the openSUSE build log for wine-devel-32bit [5] shows the i386-unix archive files being generated and installed. For 32-bit, they're using: ../configure --host=i586-suse-linux --build=i586-suse-linux --program-prefix= [...] --with-x --with-wayland --with-gstreamer --verbose Since I don't expect --with-x --with-wayland --with-gstreamer --verbose to change anything on whether archive files are built, how come the 64-bit build on OBS is not providing these *.a for x86_64-unix? I posted some more commandlines which don't seem to work correctly to the linked Bugzilla issue [2] back in December. I'm unsure if any of those I've tried there should be expected to produce correct results, so I'm focused on understanding of what's wrong with the 64-bit OBS build. Thanks for any insight, advice, pointers, or corrections you might have for me.
