[PATCH v2 0/2] MR8474: configure: Build PEs with -ffp-exception-behavior=maytrap.
by Jacek Caban (＠jacek) July 1, 2025

July 1, 2025

Fixes gdiplus tests in Clang build. When the compiler assumes non-trapping floating-point math, it may apply more aggressive optimizations. For example, in the fast path of `GdipInvertMatrix`, it may merge paired divisions into a single `divss` instruction. This can leave unused lanes whose results are ignored, but they still execute and may cause a division by zero, breaking tests that have the FP exception mask enabled. Using `-ffp-exception-behavior=maytrap` prevents the compiler from performing such transformations. It's a bit surprising that this flag also disables optimizations like those seen in the dmime tests, so there’s likely room for improvement on the compiler side. Regardless, relying on `round()` in tests isn't valid, as it's not available in msvcrt.dll and may depend on compiler-specific behavior. -- v2: configure: Build PEs with -ffp-exception-behavior=maytrap. dmime/tests: Use ceil instead of round. https://gitlab.winehq.org/wine/wine/-/merge_requests/8474

Some test cases fail due to no reading zone information. Let’s use new MRs for now, but in the future you may use a force push (e.g., `git push -f`). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8378#note_108482

[PATCH v2 0/3] MR8473: opengl32: Add an EnabledExtensions registry option.
by Rémi Bernon July 1, 2025

July 1, 2025

Some old applications crash if GL_EXTENSIONS string is longer than a certain limit. There are some vendor-specific environment variable to limit the returned extensions, but it is IMO less convenient to use than a per-application registry setting which can be set once on prefix configuration time. We have a DisabledExtensions registry key already, this adds a similar EnabledExtensions key that filters the returned extensions to only include those listed in that key, effectively limiting the size of the extensions string.

[PATCH v31 0/9] MR7650: Add support for AF_UNIX sockets (followup)
by Ralf Habacker (＠rhabacker) July 1, 2025

Follow-up of !2786, which appears to have been abandoned. Depends on !8182 # Execute minimal test case 1. in dlls/ws2_32/tests/sock.c wrap all calls to test functions after `Init()` until `test_afunix()` with #if 0 ... #endif 2. checkout wine into ~/src/wine 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)` # 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. -- v31: ws2_32: Add note in bind() for AF_UNIX sockets ws2_32/tests: In tests for AF_UNIX sockets print actual directory used ws2_32/tests: In AF_UNIX socket tests always print used path in case of errors ws2_32/tests: Add test for AF_UNIX sockets server: Fix getsockname() and accept() on AF_UNIX sockets. server: Introduce error when attempting to create a SOCK_DGRAM AF_UNIX socket. server: Allow for deletion of socket files. ws2_32: Add support for AF_UNIX sockets. ws2_32: Add afunix.h header. https://gitlab.winehq.org/wine/wine/-/merge_requests/7650
