[PATCH 0/3] MR10829: Futex optimizations
by Marc-Aurel Zent (＠mzent) May 6, 2026

May 6, 2026

This fixes [bug 54979](http://bugs.winehq.org/show_bug.cgi?id=54979). Having contention on any of the spin locks is pretty catastrophic for performance (and also causes issues with fairness), so this change tries to make collisions on the futex queues much less likely. In the worst case, not full memory barriers are issued anymore while spinning, and the time slice is yielded if it seems unreasonable that the lock holder is still executing at the moment on a CPU... -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10829

[PATCH v19 0/2] MR10393: Draft: vbscript: Check named item dispatch for Dim variable names.
by Francis De Brabandere (＠francisdb) May 6, 2026

May 6, 2026

When declaring variables with Dim in a visible named item context, check the named item's IDispatch for each variable name via GetIDsOfNames. This matches Windows VBScript behavior where Dim probes the host object before creating the variable. -- v19: vbscript/tests: Cover host-dispatch probing for top-level declarations. vbscript: Check named item dispatch for top-level declared names. https://gitlab.winehq.org/wine/wine/-/merge_requests/10393

[PATCH 0/1] MR10827: wineboot: Run services.exe from c:\windows\system32 directory.
by Dmitry Timoshkov (＠dmitry) May 6, 2026

May 6, 2026

A .Net based service detects that it's running as a service by checking if its current directory is system32, otherwise the service runs in some debugging console based mode. Service processes created by services.exe inherit its current directory, so it's enough to make sure that services.exe runs from c:\windows\system32. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10827

[PATCH v8 0/1] MR10528: oleaut32: Add fast paths for VarAdd and VarCmp with integer operands.
by Francis De Brabandere (＠francisdb) May 5, 2026

May 5, 2026

Add fast paths for `VarAdd` and `VarCmp` when both operands are simple integer types (VT_I2, VT_I4, VT_EMPTY), skipping the `VariantChangeType` / `VariantCopyInd` pipeline and the locale grab/free cycle in ucrtbase. `VarAdd` and `VarCmp` are called on every iteration of an integer For-loop (counter increment) and on every conditional comparison. Profiling VBScript workloads showed the full VARIANT conversion path dominated that cost. ### Benchmarks The suite skews heavily toward integer For-loops — most scenarios (conditionals, local reads, class property access) are measured *inside* a tight `For i = 1 To N` loop, so the loop counter itself contributes to the speedup. Numbers below are median of 3 runs on Wine with current `master` as baseline. | Scenario | Before | After | Speedup | |----------|--------|-------|---------| | Integer For-loop, empty body (10M) | 2678 ms | 364 ms | 7.4× | | If-condition inside loop (10M) | 3678 ms | 718 ms | 5.1× | | Local variable reads in loop (1M × 10) | 1247 ms | 403 ms | 3.1× | | Class property read in loop (500K) | 289 ms | 164 ms | 1.8× | | For R8 counter (not fast-pathed) | 2910 ms | 2764 ms | ~same | | String concatenation (no loop counter) | 70 ms | 70 ms | ~same | The headline numbers are a ceiling for integer-arithmetic-heavy code. Scripts where the dominant cost is string manipulation, COM dispatch, or I/O will see little change — as the last two rows show. ### Real-world impact 10-23% tick speedup on most visual pinball tables. Tables with heavier VarAdd/VarCmp integer usage benefit most. -- v8: oleaut32: Add fast paths for VarAdd and VarCmp with integer operands. https://gitlab.winehq.org/wine/wine/-/merge_requests/10528
