[PATCH v7 0/3] MR9874: wineandroid.drv: experimental bring-up fixes for Android 7.1.x
by Twaik Yont (＠twaik) 04 Mar '26

04 Mar '26

Requires #10067, fixup/followup to e0d3683d8947cd9a3cb20acdf69091b183a90861 and 4b5311c7e02aa7ab2409f8fdcd22233f116dc4bc. #### Note on authorship and language This text was translated into English and structured with the assistance of ChatGPT. The author is not a native English speaker and may struggle with written technical English; any wording issues are unintentional. #### Description This merge request is an experimental attempt to bring wineandroid.drv back to a minimally functional state on Android 7.1.x. The current Android support appears to have bit-rotted over time, likely due to a combination of internal contract changes in Wine, toolchain and NDK evolution, and the absence of continuous Android testing. The changes proposed here aim to re-establish a working baseline and make the regressions more concrete and easier to reason about. #### Test environment and context All testing so far was performed on Android 7.1.2 x86 images from the Android-x86 project, published on osboxes.org ([link](https://www.osboxes.org/android-x86/)) The primary target is i386 Wine running on x86 Android userspace. Because no up-to-date official Android build scripts were available, Wine was built using Termux as an unsupported but convenient environment for rapid testing. The Java part (WineActivity and related glue code) was built with `sharedUserId = com.termux` purely for convenience (filesystem access and faster prototyping). **Termux is explicitly not considered a supported environment and is mentioned only to provide context for the testing setup.** The build uses Android NDK r29. Since the last known functional Android Wine builds, the NDK and linker behavior have changed multiple times, including symbol visibility and relocation handling. These changes appear to have directly affected several failure modes described below. There is also a known issue with wine-preloader producing excessively large binaries under recent toolchains; a workaround exists but is not included here and is mentioned only as additional context. #### Scope of changes This merge request currently modifies only Android-specific code: - `wineandroid.drv` (native code and Java glue, including WineActivity) - android-only paths in `dlls/ntdll/unix/loader.c` No non-Android platforms are affected. #### Summary of resolved issues 1) Desktop initialization ordering regression After recent `CreateDesktopW`-related changes, `ANDROID_CreateDesktop` started running before the DESKTOP window was created. The Java glue assumed the opposite order. The fix splits desktop initialization into two phases (view setup first, desktop window attachment later via an explicit is_desktop flag) and corrects the `ANDROID_CreateDesktop` success return value. 2) Rendering stalls and `USER lock assertion` Occasional crashes with: ``` err:system:user_check_not_lock BUG: holding USER lock ``` A full memory barrier was added in the dequeue path to avoid a likely memory ordering issue. Additionally, a guard was added for a `NULL` buffer returned on successful dequeue. 3) Early startup failure in `virtual_alloc_first_teb` Wine frequently failed with: ``` err:virtual:virtual_alloc_first_teb wine: failed to map the shared user data: c0000018 ``` `virtual_init()` is now called from `JNI_OnLoad()` to reduce the likelihood of the JVM reserving the required address range before Wine initializes its virtual memory subsystem. #### Remaining issues - Window focus handling is partially broken: windows receive focus on click, but are not always raised to the front. - Despite the available desktop area being larger (e.g. 1024x696), Wine consistently reports a display resolution of 800x600. #### Limitations Wine on Android stopped functioning entirely starting with Android 8. As a result, all testing so far has been limited to Android 7.1.x. No claims are made about behavior on newer Android versions. #### Out of scope This merge request intentionally does not attempt to: - redesign IPC mechanisms - introduce new Android integration models - address Android 8+ compatibility The sole goal is to re-establish a minimally working baseline on Android 7.1.x and enable informed discussion about what regressed and how to proceed. **This is my first contribution to Wine, and I am aware that some parts of this analysis or implementation may be flawed. I would be grateful for any review comments or suggestions.** <details> <summary>Also, the screenshot of the working prototype.</summary> ![1](/uploads/666d78a712edce531a25521a2615ea9f/1.png){width=756 height=600} </details> -- v7: ntdll: call virtual_init from JNI_OnLoad to avoid early virtual_alloc_first_teb failure Wineandroid: Sanitize dequeueBuffer result and reject missing buffers. wineandroid: fix desktop init ordering after CreateDesktopW changes https://gitlab.winehq.org/wine/wine/-/merge_requests/9874

This patch applies to applications that launch processes via ShellDispatch specified as VT_EMPTY type (such as WPS PDF Editor).\ It prevents the conversion of VT_EMPTY type to the INT_4 value of 0 (i.e., SW_HIDE), which would otherwise cause the main program window not to be displayed. -- v5: shell32: ShellExecute uses SW_SHOWDEFAULT by default https://gitlab.winehq.org/wine/wine/-/merge_requests/9997

[PATCH v10 0/1] MR10193: dlls/comdlg32：Add the implementation of IServiceProvider_fnQueryService to obtain IFolderView2
by pan hui (＠panhui) 03 Mar '26

03 Mar '26

An application adds a new button using IFileDialogCustomize_AddPushButton. The application obtains IServiceProvider_iface through QueryInterface using the parameter IFileDialogCustomize_iface of the callback function IFileDialogControlEvents_OnButtonClicked, and then uses IServiceProvider_iface to pass IID_IFolderView and IID_IFolderView2 through IServiceProvider_fnQueryService to obtain IFolderView2. After that, it obtains the selected files and folders through IFolderView2_GetSelection. Currently, the implementation of obtaining IFolderView2 through IServiceProvider_fnQueryService is missing and needs to be added. -- v10: dlls/comdlg32：Add the implementation of IServiceProvider_fnQueryService to obtain IFolderView2 https://gitlab.winehq.org/wine/wine/-/merge_requests/10193

[PATCH v18 0/1] MR10191: comctl32: Implement Tile view style
by Huw Campbell (＠HuwCampbell) 03 Mar '26

03 Mar '26

The Tile View in common controls offers a compact and pretty nice way to show some additional context within the list view, without resorting to the full reports mode. It's used a lot in explorer like programs where things like the disk size and file type are shown. But, it's been sitting unimplemented in wine for a long time. I've just spent a few days implementing this by: - Building a small test program in windows to get a feel for how it works - Hacking just enough to get something displaying - Writing a test suite to try and understand the ownership model, getting, and setting, and the various messages passed by windows. - Fixing up the implementation. - Adjusting my program to use I_COLUMNCALLBACK in windows and testing that. - Fixing my implementation to match the behaviour observed. Full disclosure, I originally started this implementation within the ReactOS build system as I had that compiling installed on my Windows box (my Mac is an M1 so doesn't play very nicely with Wine). I've since spun up a Linux VM and continued the work there. All bugs and misunderstandings are my own; I used clean room techniques (read MSDN, write a test program, write tests, compare results, iterate). Interesting things: - I initially wrote layout code for tiling mode as well, but a few rounds of playing with my test program and various layouts and settings (things like `LVS_ALIGNTOP`, `LVS_AUTOARRANGE` and `LVS_ALIGNLEFT`) for both tile mode and icon mode, convinced me that they use same layout logic (or close enough to). - I noticed some differences in Wine's Icon mode layout as compared to Windows 10. - I didn't fix these, one thing at a time. - I noticed and fixed a bug in SetView, where `UpdateItemSize` was called _after_ `Arrange`; that doesn't work. - The Text colours are really odd, if set to black the sub items show up gray, but any other colour and they're the same as the main. - Layout is tricky, in windows it looks like the first item (file name for example) can flow to 2 lines, and subitems are restricted to 1 - But this is really subtle, using GetItemMetrics kind of assumes there's no 'interference' from other items. - If we're on subitem 2, I don't want to have to fetch 0 and 1 to render their sizes before calculating my own, it seems like an `O(N^2)` situation off the bat. - I used a sidechannel from DrawItems, I'm open to other ideas here. - I haven't tested message passing, many of the test failures for listview at the moment look like sequencing errors for messages. I didn't look into it. - The auto mode on Windows 10 looks quite sophisticated, in that it examines many (all) items before deciding the best size. I haven't done anything interesting for auto size mode. - Not really interesting, but the tabs vs spaces situation in this file is a mess. Next Steps ========== - ~~Test with image lists loaded as well~~ - Hope for feedback here (particularly for messages) - Think about auto sizing. - Think about vertical centering within the space. Windows seems to have this as an option, though I haven't discovered how that works just yet. If Merged ========= Now that I have a pretty good grasp of how this component works and lays things out, once this is merged I'll see if I can do Groups as well. Pictures: ======== Windows ListView with Tile mode active. The first entry uses a Callback for the text and the columns layout, while the second is static. ![image](/uploads/8c9d1eb4c362a07c74291b49989c4fd7/image.png){width=300} Wine (with an image list as well) ![image](/uploads/81392817be792c2b95c962be83145a72/image.png){width=300} And Explorer++ ![image](/uploads/877966fc2ded1901cbb000c75f932719/image.png){width=400} Known Issues: ============= - Some highlighting seems a bit janky, I've a quick fix for this, but I think it would be best handled along with: - Hit testing when sub items are touched seems janky too.

If Wine is fixed, we want the test to succeed in a `todo_wine` block (which will show up as a failure) so we can know when the test starts working. By checking hr beforehand, we won't get any report when Wine is fixed, which is not what we want. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10193#note_131188
