[PATCH v50 0/9] MR7650: Add support for AF_UNIX sockets (followup)
by Ralf Habacker (＠rhabacker) Aug. 23, 2026

Aug. 23, 2026

Follow-up of !2786, which appears to have been abandoned. Depends on !8182, !8575, !8578, !8863, !9831, !9835 # Execute minimal test case 1. checkout wine into \~/src/wine 2. in dlls/ws2_32/tests/sock.c wrap all calls to test functions after `Init()` until `test_afunix()` with #if 0 ... #endif 3. build into \~/src/wine-build 4. run ``` (cd ~/src/wine-build; \ WINEPREFIX=~/src/wine/.wine \ ../wine/tools/runtest -q -P wine -T . -M ws2_32.dll \ -p dlls/ws2_32/tests/i386-windows/ws2_32_test.exe sock) ``` or without the wrapper and some imported wine debug channels enabled ``` (cd ~/src/wine-build; WINEPREFIX=~/src/wine/.wine \ WINEDEBUG=+file,+winsock \ WINEDLLOVERRIDES=';ws2_32.dll=b' \ WINETEST_PLATFORM=wine \ ./wine dlls/ws2_32/tests/i386-windows/ws2_32_test.exe sock) ``` # How to debug wineserver Since `wineserver` runs in the background, simple calls to printf() will show nothing when the test case is executed. A workaround is to open a file and call fprintf() to write debug messages to this file, which can then be inspected. The wineserver man page mentions that there is limited support to control wineserver debugging by using `WINEDEBUG=+server` ``` -d[n], --debug[=n] Set the debug level to n. 0 means no debugging information, 1 is the normal level, and 2 is for extra verbose debugging. If n is not specified, the default is 1. The debug output will be sent to stderr. wine(1) will automatically enable normal level debugging when starting wineserver if the +server option is set in the WINEDEBUG variable. ``` However, higher levels probably cannot be set in this way. # Problems with synchronized log output - The Windows test binary prints test failures to stdout (line-buffered or fully buffered). - Wine/Wineserver debug prints to stderr (unbuffered). When merged into a single stream (stderr+stdout), stdout lines get fragmented and interleaved between Wine/Wineserver trace messages., which looks like this: ``` 012c:trace:file:NtWriteFile (0xd,(nil),(nil),(nil),0x6afd40,0x4190bc,0x00000012,(nil),(nil)) [?25lsock.c[?25h012c:trace:file:NtWriteFile = SUCCESS (18) 0124:trace:file:NtDeviceIoControlFile (0x10,(nil),(nil),(nil),0x74ddd0,0x00504000,(nil),0x00000000,0x74ddcc,0x00000004)xts={} ) ``` Unfortunately, synchronized logs are important for analyzing processes. Combining synchronized strace and wine trace messages can be generated with ``` #!/bin/bash -x p=$PWD cd ~/src/wine-build WINEPREFIX=~/src/wine/.wine \ WINEDEBUG=+file,+winsock \ WINEDLLOVERRIDES=';ws2_32.dll=b' \ WINETEST_PLATFORM=wine \ stdbuf -o0 -eL strace -tt -f -o strace.log \ ./wine dlls/ws2_32/tests/i386-windows/ws2_32_test.exe sock 2>&1 | ts 'WINE %H:%M:%.S' > wine.log cat wine.log strace.log | grep -v 'write(\|read(\|rt_sigprocmask' | sort -k 2 > $p/trace.log ``` # How to debug a wine test case At https://gitlab.winehq.org/wine/wine/-/blob/master/tools/runtest#L151 there is mentioned a environment variable name `WINETEST_WRAPPER`, with which it may be possible to run gdb to debug test cases ``` (cd ~/src/wine-build; make -j10 ;\ WINETEST_WRAPPER="gdb --args" \ WINEPREFIX=~/src/wine/.wine \ ../wine/tools/runtest -P wine -T . -M ws2_32.dll \ -p dlls/ws2_32/tests/i386-windows/ws2_32_test.exe sock) Reading symbols from ./wine...

Changing VkSwapchainCreateInfoKHR imageColorSpace from VK_COLOR_SPACE_SRGB_NONLINEAR_KHR for `wined3d_swapchain_vk_create_vulkan_swapchain()` had no effect despite enabling VK_EXT_swapchain_colorspace for dlls/win32u/vulkan.c `convert_instance_create_info():` https://docs.vulkan.org/refpages/latest/refpages/source/VkColorSpaceKHR.html Therefore converting UNORM to SRGB was chosen similar to how the GL renderer seems to handle it: ``` static const struct wined3d_format_srgb_info format_srgb_info[] = { {WINED3DFMT_R8G8B8A8_UNORM_SRGB, WINED3DFMT_R8G8B8A8_UNORM}, {WINED3DFMT_BC1_UNORM_SRGB, WINED3DFMT_BC1_UNORM}, {WINED3DFMT_BC2_UNORM_SRGB, WINED3DFMT_BC2_UNORM}, {WINED3DFMT_BC3_UNORM_SRGB, WINED3DFMT_BC3_UNORM}, {WINED3DFMT_B8G8R8A8_UNORM_SRGB, WINED3DFMT_B8G8R8A8_UNORM}, {WINED3DFMT_B8G8R8X8_UNORM_SRGB, WINED3DFMT_B8G8R8X8_UNORM}, {WINED3DFMT_BC7_UNORM_SRGB, WINED3DFMT_BC7_UNORM}, }; ``` Its unclear whether SRGB conversion should always happen or only for particular games so the patch leaves the Vulkan renderer without SRGB conversion by default. Therefore the patch adds a new WINE_D3D_CONFIG flag named "vk_swap_srgb" to force the Vulkan renderer to perform SRGB conversion for the swapchain. By default vk_swap_srgb is set to FALSE or 0: `WINE_D3D_CONFIG=vk_swap_srgb=0,renderer=vulkan` To force vk_swap_srgb to TRUE or 1: `WINE_D3D_CONFIG=vk_swap_srgb=1,renderer=vulkan` For example, launching Frostpunk via the following after the patch fixes the dark rendering for Vulkan and appears brighter similar to the GL renderer: `WINEDEBUG=-all mangohud --dlsym WINE_D3D_CONFIG=csmt=0x1,renderer=vulkan,vk_swap_srgb=1 WINEPREFIX=/home/any/wine_stianlow_wow64_new_pfx ~/tmp/wine_stianlow_wow64_new_install/bin/wine /home/any/wine_stianlow_wow64_new_pfx/drive_c/GOG\ Games/Frostpunk/Frostpunk.exe` Some SRGB handling was added several years ago but not for mapping UNORM to SRGB that this patch adds: ``` 6f55c8d1c56 * wined3d: Use an sRGB fallback format for sRGB formats in wined3d_swapchain_vk_select_vk_format().

Hi @BigBlueGnu I locally switched to this PR to see if I could try and move this PR along (Hopefully the instructions below are not too verbose...) To fix the current MR, you need to do the following: 1. `git rebase -i upstream/master` 2. change `pick` to `drop` for all commits except with `Update 2 files` 3. `git reset "HEAD^"` 4. `git add programs/winevdm/winevdm.c` 5. `git commit` Put this: ``` winevdm.c: Fix how Wine handles DOS-era PIF files. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=3638 ``` 6. `git restore dlls/winex11.drv/keyboard.c` 7. `git rebase --continue` Then you can just force push and it should be cleared up. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/11315#note_149588

by Kyle Yang (＠kyle) Aug. 22, 2026

When export forwarders have circular dependencies, Wine currently causes a stack overflow, which differs from Windows behavior.
