Wine 8.0.2 fails to create a window
by volker.schlegel＠tutanota.com Dec. 1, 2023

Dec. 1, 2023

Hello everyone,I've recently switched from Manjaro to Mint, and just installed WINE again.Latest stable release, 8.0.2, from the wineHQ repos.Any application trying to create a window seems to crash.Example crash dump (new prefix): https://pastebin.com/T6WG9EhQ Since it seems to be a graphics issue, here is the output of inxi -G: https://pastebin.com/SvURv3fYWhile searching for a fix I stumbled across this bug, might be related? https://bugs.winehq.org/show_bug.cgi?id=51210"Deactivate your GPU" isn't really a solution though in my opinion.I'd try to actually fix it myself (I've built wine myself before, and I have written quite a bit of C code), but I've never used Vulkan or OpenGL, so any help is appreciated!

GCC 4.3 support and language features
by Fabian Maurer Nov. 22, 2023

Nov. 22, 2023

Hello wine-devel, I wanted to follow up on the discussion on https://gitlab.winehq.org/wine/ wine/-/merge_requests/3059 For those not in the loop: The question came up what GCC version is the oldest supported one, and which language features can't be used in Wine. Is there already a wiki entry on this? Associated bug report: https://bugs.winehq.org/show_bug.cgi?id=54601 (Compilation fails with gcc 4.3.4 (error: unknown field ‘Type’ specified in initializer) I have a bunch of gcc 4.3 patches, and if it's supported, I think it would be useful getting those in before the next stable. Although ongoing gcc 4.3 support is probably a bit of work, since most people don't test against gcc 4.3 compatibility so there's some "regressions" from time to time. An option would be to just patch it when someone complains, which would be the most reasonable to me. Or just cap it at 4.8 which currently works. In the end, some compiler will be too old, so where is the line? In a similar vein, what about https://bugs.winehq.org/show_bug.cgi?id=20474 (Wine can't be built with GCC in C99 mode) Is this a supported setup? IMHO itwould be too much effort work to get this working, but I don't make the decisions. Regards, Fabian Maurer

Upcoming vkd3d 1.10 release
by Henri Verbeet Nov. 8, 2023

Nov. 8, 2023

Hi all, The planned release for vkd3d 1.10 is about 4 weeks away. As usual, that means the development branch will become increasingly frozen as we're nearing release. 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 all the vkd3d tests pass on your hardware, and please send fixes if they don't. - Review and improve the documentation. - Apply your best judgment about which patches are appropriate for the current stage of the release process. If you're a downstream user of vkd3d, please test your applications for regressions, and file bug reports if you find any. If you're the maintainer of a Wine module that (indirectly) depends on vkd3d, like e.g. d2d1, d3dx9, d3dcompiler, or any of the core Direct3D modules, that includes making sure the unit tests still pass with the new version. The planned release date for the release following vkd3d 1.10 is currently sometime in March. Regards, Henri

This is indeed a pain point. So much that at some point I even began to write a tentative solution to that, which so far I have only shared inside CodeWeavers. There is in fact (as far as I am aware) no reason why it should not be made available publicly, so here it is, I just released it: https://gitlab.winehq.org/giomasce/minitestbot Here is the train of thoughts that brought to MiniTestBot: * As you say, accessing the TestBot/CI environment is hard: the interface is limited and people have to share the available time, so if many people are hitting the TestBot/CI at the same time they have to wait for each other's job, which can be frustrating. * Much better it would be if you could run the TestBot/CI's environment directly on your hardware. Then you don't compete with others anymore and you can interact with your VM however you please, including changing settings and installing stuff. * As you say, the problem is that we can't just distribute Windows images. But we can distribute the scripts used to generate them, which is essentially what MiniTestBot does! The MiniTestBot user needs to independently provide the Windows ISO (Microsoft distributes them for free, at least for some Windows versions) and is directly responsible for complying with licenses, while distributing the scripts does not infringe any copyright, as they are all free software and free of Microsoft intellectual property. Though I am not a lawyer, so don't take this as legal advice! :-) * If the TestBot/CI used images generated with these scripts (or, rather, what they would become after having made better) we'd have both the possibility to run tests in the cloud, which is handy for many reasons, and the possibility to run them on premises in the same environment, which is handy in other cases. I hope that would help to remove at least some of the frustration of debugging tests on Windows. In practice MiniTestBot is a few scripts that take a Windows image and (nearly) automatically create an image out of it, together with other scripts to submit job to be automatically be executed inside that image, TestBot style. It is really a proof of concept at this stage, but I'm already finding it useful for development. At least another person in CodeWeavers told me they find it useful. It would require some more work to be integrated in the TestBot/CI, but that work shouldn't be impossible to do. What do you think of this approach? Also, I am happy to receive comments, suggestions and MRs (yes, those too!) for MiniTestBot. Gio.

Win16 tests
by Zeb Figura Oct. 23, 2023

Oct. 23, 2023

Hello! The idea of having tests for our win16 functionality has been raised every so often, but never actualized. I would like to change that now. I think win16 has been broken several times recently, especially with large scale refactoring like the PE conversion and wow64 work, and I'd like to put tests in place to stop that happening. I'd also like to have a way to easily *write* tests for nontrivial functionality, which is currently something of an ordeal. By my understanding, the big blocker for having win16 tests in tree is the lack of a usable win16 compiler. Existing win16 compilers are mostly hard to find; OpenWatcom is sometimes mentioned, but that only has win32 builds (as far as I'm aware), which makes it hard if not impossible to integrate into Wine. I've spent a while over the past year or so trying a certain idea, where we write a small win16 entry point, and use generic thunks to call into win32 code, then use generic thunks the other way (WOWCallback16Ex) to call back into win16 functions. I managed to get a working PoC that actually worked on Windows XP; however, it did not work on Windows 98 [1]. In light of this, I tried a different approach. I considered but ultimately rejected the idea of introducing Win16 support into GCC [2], and instead tried an experiment to see if I could write an extremely minimalist, non-optimizing Win16 compiler myself from "scratch" [3]. It turns out that I could, in the span of what didn't end up being more than a couple months' worth of weekends. The compiler is called Rosé, and it lives here: https://gitlab.winehq.org/zfigura/rose It is not fully featured; it's still missing a few notable pieces (in particular: unions, multiple code segments) but it is reasonably complete, and I was able to use it to compile a modified version of winetest.exe, and produce working executables for Windows 98. It is therefore my proposal to use this compiler in Wine, and write in-tree Win16 tests. Here are some of the important considerations involved in this proposal: * The compiler is small and could potentially be easily just imported into Wine. I don't have any feelings about continuing to maintain it outside of Wine—i.e. it could easily just be imported and any further development done in Wine (much like e.g. widl). "Small" here means about 15k LoC across a few files, including the builtin CRT and headers. * NE executables, unlike both their predecessor (MZ) and successor (PE), cannot output to a controlling console, and in general have no concept of a stdin/stdout/stderr. This does not fit well with wine tests, which are built to run with a console. There is also not much in the way of IPC available to a win16 process. They can, on the other hand, open a file and output to it. For Marvin (or gitlab CI), this is not a huge concern, but for development it's a bit more important. In light of this we may want to write a small win32 wrapper for win16 tests, possibly one that self-extracts the win16 test. * In order to properly test Win16 we need a contemporaneous test VM, I think ideally 98. A modern 32-bit Windows machine (of which I think we still have some) will *run* 16-bit code, and may be usable to test *some* functionality, but I do not think the results can be trusted. This is probably a more general problem—I think our current ability to test native ddraw is similarly worthless. (ddraw is also harder, though, because we need contemporaneous *hardware* as well.) There may be other areas where our current CI is not very valuable and we really do want to test old Windows versions, although I can't think of any off the top of my head. Thoughts and opinions? If not (as per usual) I will try to put together a patch series soon. --Zeb [1] In a sense this is actually very similar to how we currently implement 16-bit DLLs in Wine, except that we use a private thunk instead of the exported generic thunks [CallProcEx32W], so I spent some time refactoring various parts of krnl386 and winebuild to match my proposed design. This was going well up until I tried running the executable on Windows 98. It turns out that, unlike with NT, one cannot call any win32 functions from the 32-bit DLL without crashing. This may not be prohibitive per se [if we avoid ever making any win32 calls] but it did impose some pretty severe limitations. It's also worth mentioning that the process of refactoring was *very* convoluted, things had to be moved around very carefully in order to work. [2] The idea of introducing compiler support into GCC has obvious advantages: not just the reuse of frontend and optimization code, but the dialect is something that will already be perfectly familiar to a Wine developer. However, it also has disadvantages: it would take a lot of time to become familiar with gcc, and I expect that segmented address spaces will be very hard to fit into the GCC code and probably not accepted upstream. [3] In fact it is not built from scratch, but rather built from the HLSL compiler. This is largely because I am very familiar with the HLSL compiler, and familiarity is very important. I also found it far less daunting to start with the HLSL compiler, rip out everything specific to HLSL, rather than to start from scratch even using the HLSL compiler as a model.
