[PATCH v2 0/2] MR8474: configure: Build PEs with -ffp-exception-behavior=maytrap.
by Jacek Caban (＠jacek) 01 Jul '25

01 Jul '25

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

MAX messenger crashes without getting a valid pointer to PersistentZoneIdentifier COM object. Adding a stubbed COM object solves the problem -- v2: urlmon: Add PersistentZoneIdentifier COM object stubs https://gitlab.winehq.org/wine/wine/-/merge_requests/8456

[PATCH v2 0/3] MR8473: opengl32: Add an EnabledExtensions registry option.
by Rémi Bernon 01 Jul '25

01 Jul '25

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) 01 Jul '25

01 Jul '25

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

[PATCH 0/1] MR8467: conhost: Implement F1 and F3 support for history retrieval.
by Joe Souza (＠JoeS209) 01 Jul '25

01 Jul '25

F1 and F3 allow partial retrieval of previous entry from console history. They are used as shortcuts such that if the following were entered at the command line: md tmptmp cd <F3> F3 will retrieve the previous line from history past the cursor position, and be auto-completed to "cd tmptmp". F1 works in a similar fashion, but with one character at a time. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8467
