[PATCH v2 0/1] MR10366: vbscript: Fix For loop getting stuck when expression evaluation fails with On Error Resume Next.
by Francis De Brabandere (＠francisdb) March 27, 2026

March 27, 2026

When a For..To loop's bound expression fails (e.g. UBound on Empty) and On Error Resume Next is active, the error handler fills the step/to stack slots with VT_EMPTY. On the next iteration, VarCmp fails on these values and the error propagates back into the loop, causing an infinite loop. Fix this by handling VarCmp failures in interp_step: exit the loop and report error 92 (For loop not initialized). Also make interp_incc ignore VarAdd failures so execution reaches interp_step for proper cleanup.

[PATCH v5 0/1] MR10362: vbscript: Support chained call syntax like dict.Keys()(i).
by Francis De Brabandere (＠francisdb) March 27, 2026

March 27, 2026

Treat '(' after tEMPTYBRACKETS as an argument list opener in the lexer, so that expressions like GetArr()(0) or dict.Keys()(i) parse correctly. Also dereference VT_BYREF|VT_VARIANT results in vcall so chained indexing on call results works at runtime. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=58051 This includes some of the work done in !10308, preferably that one is merged first. -- v5: vbscript: Support chained call syntax like dict.Keys()(i). https://gitlab.winehq.org/wine/wine/-/merge_requests/10362

[PATCH v4 0/1] MR10314: vbscript: Convert string to number for comparison operators.
by Francis De Brabandere (＠francisdb) March 27, 2026

March 27, 2026

When one operand was a string and the other numeric, VBScript should have converted the string to a double before comparing. VarCmp did not do this automatically, resulting in incorrect string comparison.

[PATCH v17 0/1] MR10244: vbscript: Fix Sub first argument parentheses handling.
by Francis De Brabandere (＠francisdb) March 27, 2026

March 27, 2026

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=54177 Fix parsing of expressions like `Sub (i - 20) * 8,y` where a space-separated parenthesized expression followed by a binary operator(*` /` \` ^` &`) was incorrectly treated as call argument parentheses instead of expression grouping. If you look at all the extra test cases in `lang.vbs` you will see which parentheses related issues this solves. I have been testing with a repo full of scripts: https://github.com/sverrewl/vpxtable_scripts There are still quite some compiler issues left but this addresses the biggest parser issues. -- v17: vbscript: Fix Sub first argument parentheses handling. https://gitlab.winehq.org/wine/wine/-/merge_requests/10244

[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.
