[PATCH v3 0/2] MR7312: msvcp: Avoid explicitly aligning fpos_mbstatet.
by Jacek Caban (＠jacek) 12 Feb '25

12 Feb '25

Based on Piotr's findings. On MSVC i386 targets, structs requiring alignment greater than 4 are never passed by value. Clang follows the same behavior in MSVC mode (see [1] for details and [2] for a follow-up that applies this logic when fields, not necessarily the entire struct, are aligned). A number of ios functions take fpos_mbstatet as an argument and expect it to be passed by value.

[PATCH v4 0/4] MR7256: ntdll: monotonic_counter and NtQuerySystemTime performance improvements on macOS.
by Marc-Aurel Zent (＠mzent) 12 Feb '25

12 Feb '25

`mach_continuous_approximate_time()` has the necessary precision for win32 ticks and can be up to 4x faster than `mach_continuous_time()`. Also `clock_gettime( CLOCK_REALTIME, &ts )` calls always end up in `__commpage_gettimeofday( struct timeval *tp )`: ``` * frame #0: 0x00007ff806788763 libsystem_kernel.dylib`__commpage_gettimeofday frame #1: 0x00007ff8066709a3 libsystem_c.dylib`gettimeofday + 45 frame #2: 0x00007ff806678b31 libsystem_c.dylib`clock_gettime + 117 ``` These extra calls, setup and converting from one struct format to another costs another 60 CPU cycles and in my testing makes `NtQuerySystemTime` approximately 30% faster as well with this MR. This is a fairly hot code path (especially when using certain out-of-tree in process synchronization patch sets), so probably worth the optimization here. All of these APIs are available since 10.12. -- v4: ntdll: Replace '0' with 'NULL' in gettimeofday() calls. ntdll: Use gettimeofday in system_time_precise on macOS. ntdll: Use __commpage_gettimeofday in NtQuerySystemTime on macOS. ntdll: Always use mach_continuous_approximate_time on macOS. https://gitlab.winehq.org/wine/wine/-/merge_requests/7256

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=56106 I'm not sure why there's a IRandomAccessStreamReferenceStatics interface in WinTypes. Perhaps it was supposed to be queried from one of the classes there? I've seen something similar with other classes. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7308

[PATCH 0/1] MR7316: win32u: Avoid using uninitialized variable.
by Ruslan Garipov (＠ruslangaripov) 12 Feb '25

12 Feb '25

When dlls/win32u fails to load/initialize the \`FreeType font library', a device context object ends up with the only GDI driver attached -- `null_driver`. The latter implements the `pGetTextMetrics` callback function as do-nothing code. This causes the `NtGdiGetTextMetricsW()` function to fail not modifying fields of its `metrics` argument. In result the `normalize_nonclientmetrics()` ends up with uninitialized `tm` local variable after call to the `get_text_metr_size()` function. Using uninitialized fields of the `TEXTMETRICW` structure gives unpredictable results. This memset(3)'s the `tm` structure before using. After that, even if we failed to load the \`FreeType font library', the \`CaptionHeight', \`SmCaptionHeight' and \`MenuHeight' metrics keep their current values (the `normalize_nonclientmetrics()` function is called after `get_twips_entry()` callback function, thus value of an entry should not be negative). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7316
