[PATCH v5 0/2] MR10571: ntdll: Add NtCreateWaitablePort stub
by Rose Hellsing (＠axtlos) April 6, 2026

April 6, 2026

Some application call NtCreateWaitablePort, which made them crash since it wasn't available. By implementing a stub applications will at least not completely crash. Tested with StarMoney 10, which now throws an internal error instead of crashing.

[PATCH 0/1] MR10574: ntdll: mirror debug output to logcat on Android
by Twaik Yont (＠twaik) April 6, 2026

April 6, 2026

Mirror Wine debug output to Android logcat on Android builds. Android is effectively an embedded platform and does not provide a convenient standard stdout/stderr workflow. Capturing debug output by redirecting it to a file is also awkward in practice, while logcat provides a straightforward way to inspect live logs on-device. Load `__android_log_print` from liblog in `dbg_init()` and emit debug output through the `WineOut` tag while preserving the existing stderr path. For cases where file logging is preferred, Wine already provides a separate mechanism to set `WINEDEBUG` and redirect the output to a file. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10574

[PATCH v6 0/1] MR10500: vbscript: Defer For loop control variable assignment until all expressions are evaluated.
by Francis De Brabandere (＠francisdb) April 6, 2026

April 6, 2026

On Windows, when a For loop expression (from, to, or step) fails with On Error Resume Next, the control variable is not modified and error 92 (For loop not initialized) is set at the next iteration. Wine previously assigned the from value before evaluating to/step. Restructure compile_forto_statement to evaluate all three expressions before assigning to the control variable. On expression failure, error recovery enters the body with empty sentinel values so that OP_step detects the uninitialized state and sets error 92. Also return error 92 from OP_incc when VarAdd fails. -- v6: vbscript: Defer For loop control variable assignment until all expressions are evaluated. https://gitlab.winehq.org/wine/wine/-/merge_requests/10500

[PATCH v11 0/1] MR10405: vbscript: Return proper error for undefined variables with Option Explicit.
by Francis De Brabandere (＠francisdb) April 6, 2026

April 6, 2026

When Option Explicit is set and an undefined variable is used, return VBS error 500 (Variable is undefined) with the variable name in the description, matching Windows behavior. Previously Wine returned E_FAIL with no description. -- v11: vbscript: Return proper error for undefined variables with Option Explicit. https://gitlab.winehq.org/wine/wine/-/merge_requests/10405

[PATCH v2 0/1] MR10536: vbscript: Fast-path stack_pop_bool for VT_BOOL.
by Francis De Brabandere (＠francisdb) April 6, 2026

April 6, 2026

Skip the expensive VariantChangeType call in stack_pop_bool when the variant is already VT_BOOL, which is the common case after comparison operators (OP_gt, OP_lt, OP_equal, etc.). Every If, ElseIf, While, and Do-While condition goes through jmp_false/jmp_true which calls stack_pop_bool, so this eliminates a redundant VT_BOOL-to-VT_BOOL conversion on every branch. This closed the If-condition gap from 1.5–2.1× slower than Windows down to 1.0–1.7× slower, with pure boolean tests reaching parity. -- v2: vbscript: Fast-path stack_pop_bool for VT_BOOL. https://gitlab.winehq.org/wine/wine/-/merge_requests/10536

[PATCH v4 0/5] MR10544: vbscript: Use ASCII-only case-insensitive compare for identifier lookups.
by Francis De Brabandere (＠francisdb) April 6, 2026

April 6, 2026

VBScript identifiers are ASCII-only, Windows rejects all non-ASCII characters (Latin-1, Cyrillic, CJK) at the lexer level with error 1032 "Invalid character". Replace the locale-aware `wcsicmp()` with an inline ASCII-only `vbs_wcsicmp()` for all identifier comparisons. This avoids the expensive locale grab/free cycle (`get_current_locale_noalloc`/`free_locinfo`) that dominated profiling at 87–95% of CPU time in identifier lookup paths. Also restrict the lexer's `is_identifier_char()` and identifier-start check to ASCII-only, matching Windows behavior. Tests added for non-ASCII character rejection (é, ß, ü, Cyrillic) in identifiers. ### Benchmark results (best-of-3, before → after) | Benchmark | Before | After | Change | |---|---:|---:|---:| | Class prop read ×500k | 2558 ms | 160 ms | **−93.7%** | | GetRef loop ×200k | 15988 ms | 296 ms | **−98.1%** | | Empty For 10M | 4808 ms | 242 ms | **−95.0%** | | Nested For 10M | 6367 ms | 253 ms | **−96.0%** | | Local vars 10M | 9437 ms | 390 ms | **−95.9%** | | Dict.Exists ×100k | 300 ms | 113 ms | **−62.3%** | | If boolvar 10M | 7882 ms | 988 ms | **−87.5%** | | String concat ×2000 | 78 ms | 70 ms | −10.3% | Identifier-heavy operations see **10–50× speedups**. String concat (I/O-bound, not lookup-bound) is unchanged as expected. -- v4: vbscript: Replace wcsicmp with vbs_wcsicmp in compiler, globals, and dispatch. vbscript: Add vbs_wcsicmp and use it in interpreter. vbscript: Use ASCII-only case folding in check_keyword. vbscript: Handle vertical tab and form feed as whitespace in lexer. vbscript: Restrict identifier characters to ASCII-only. https://gitlab.winehq.org/wine/wine/-/merge_requests/10544
