[PATCH v3 0/1] MR10450: vbscript: Return correct error for array dimension mismatch and NULL array access.
by Francis De Brabandere (＠francisdb) March 27, 2026

March 27, 2026

Return VBSE_OUT_OF_BOUNDS (error 9, "Subscript out of range") instead of E_FAIL for array dimension mismatch in array_access() and for NULL SAFEARRAY access in variant_call() and do_mcall(), matching native Windows behavior. -- v3: vbscript: Return correct error for array dimension mismatch and NULL array access. https://gitlab.winehq.org/wine/wine/-/merge_requests/10450

[PATCH v7 0/1] MR10404: Draft: vbscript: Reject arguments on Class_Initialize and Class_Terminate.
by Francis De Brabandere (＠francisdb) March 27, 2026

March 27, 2026

Windows returns error 1053 when Class_Initialize or Class_Terminate are declared with arguments. Add the same check in compile_class() and store source location in function_decl_t for accurate error reporting. -- v7: vbscript: Reject arguments on Class_Initialize and Class_Terminate. https://gitlab.winehq.org/wine/wine/-/merge_requests/10404

[PATCH v12 0/1] MR10368: vbscript: Implement Eval, Execute, and ExecuteGlobal.
by Francis De Brabandere (＠francisdb) March 27, 2026

March 27, 2026

Eval compiles the string as an expression and returns the result. ExecuteGlobal compiles and executes the string at global scope. Execute compiles and executes the string in the calling scope. When called from within a Sub or Function, Eval and Execute use the calling scope for variable resolution, accessing local variables and arguments. When called from global scope, they fall back to exec_global_code. ExecuteGlobal always executes in global scope. The calling scope is passed through script_ctx_t.caller_exec, which exec_script picks up and stores on exec_ctx_t.caller. The interpreter's lookup_identifier checks the caller's locals, arguments, and dynamic vars when running FUNC_GLOBAL code with a caller context set.

[PATCH v2 0/1] MR10466: ntdll: Consider cgroup CPU limits in init_cpu_info().
by Hiroki Awata (＠castaneai) March 27, 2026

March 27, 2026

On Linux, `init_cpu_info()` uses `sysconf(_SC_NPROCESSORS_ONLN)` which returns the host machine's total CPU count, ignoring cgroup CPU bandwidth limits. This causes applications that scale thread counts based on `GetSystemInfo().dwNumberOfProcessors` to over-subscribe CPUs in container environments (Docker, Kubernetes). This MR reads cgroup v2 `cpu.max` and cgroup v1 `cpu.cfs_quota_us`/`cpu.cfs_period_us` to determine the effective CPU limit, and clamps the reported processor count accordingly. For cgroup v2, it walks up the hierarchy to find the most restrictive quota. Falls back to `sysconf` when no cgroup limit is configured. GNU coreutils 9.8 (September 2025) added similar cgroup v2 awareness to `nproc`: https://github.com/coreutils/coreutils/issues/108 Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=59556 ## Verification Verified with Wine built from this branch running inside Docker containers (cgroup v2). **Environment:** Docker on Linux (4-core host), Wine 11.4 with this patch applied. ### Without CPU limit ``` $ cat /sys/fs/cgroup/cpu.max max 100000 $ wine cmd /c "echo %NUMBER_OF_PROCESSORS%" 4 ``` All 4 host CPUs are reported. No override is applied when `cpu.max` is unlimited. ### With `--cpus=1.4` ``` $ cat /sys/fs/cgroup/cpu.max 140000 100000 $ wine cmd /c "echo %NUMBER_OF_PROCESSORS%" 1 ``` ### With `--cpus=1.5` ``` $ cat /sys/fs/cgroup/cpu.max 150000 100000 $ wine cmd /c "echo %NUMBER_OF_PROCESSORS%" 2 ``` ### With `--cpus=2.0` ``` $ cat /sys/fs/cgroup/cpu.max 200000 100000 $ wine cmd /c "echo %NUMBER_OF_PROCESSORS%" 2 ``` ### With `--cpus=2.4` ``` $ cat /sys/fs/cgroup/cpu.max 240000 100000 $ wine cmd /c "echo %NUMBER_OF_PROCESSORS%" 2 ``` ### With `--cpus=2.5` ``` $ cat /sys/fs/cgroup/cpu.max 250000 100000 $ wine cmd /c "echo %NUMBER_OF_PROCESSORS%" 3 ``` The rounding uses `(double)quota / period + 0.5`, which rounds to the nearest integer. For example, `--cpus=1.4` rounds down to 1, while `--cpus=1.5` rounds up to 2. -- v2: ntdll: Consider cgroup CPU limits in init_cpu_info(). https://gitlab.winehq.org/wine/wine/-/merge_requests/10466
