[PATCH v11 0/6] MR10419: ntdll: Fix thread stops inside __wine_syscall_dispatcher
by Hoshino Lina (＠hoshinolina) March 23, 2026

March 23, 2026

When SIGUSR1 is called while running inside `__wine_syscall_dispatcher`, the CPU context is not in a consistent state. To ensure that the captured context is always consistent: * If the SIGUSR1 arrives while saving the context, set a flag and defer handling it until after the context is fully saved. * If the SIGUSR1 arrives while restoring the context, rewind and retry restoring the context from the beginning. The latter relies on context restore being idempotent. The only case where that is not true is when the instrumentation callback is enabled. To address this, first make that path idempotent by saving the user %rip into %r10 in paths that enable the instrumentation callback. This fixes a regression introduced by 0a5f7a710365 which started leaking bogus SP values, but also generally fixes all other register value leaks due to SIGUSR1 racing with the syscall dispatcher. Supersedes: !10232 (FYI, the threadctx test introduced in this MR is stricter and also checks %rip, which will fail with that previous MR). Fixes: 0a5f7a710365 ("ntdll: Switch to the user stack before restoring the %fs register.") \ Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=59333 -- v11: gitlab: Run ntdll tests with win64 architecture. ntdll/tests: Abort wow64 tests early if wow64 is unavailable ntdll/tests: Add a test for interrupted syscall handling https://gitlab.winehq.org/wine/wine/-/merge_requests/10419

[PATCH v7 0/1] MR10386: Draft: vbscript: Add tests for specific compile error codes.
by Francis De Brabandere (＠francisdb) March 23, 2026

March 23, 2026

Add error code definitions and string resources for compile errors (1002-1057) and todo_wine tests to verify the error codes returned via OnScriptError. Currently Wine returns error code 0 (generic syntax error) for most cases instead of the specific codes Windows returns. -- v7: vbscript: Return proper error codes for compile errors. https://gitlab.winehq.org/wine/wine/-/merge_requests/10386

[PATCH v13 0/2] MR10295: Fix ImageGetDigestStream
by Trent Waddington (＠trent.waddington) March 23, 2026

March 23, 2026

ImageGetDigestStream is used to hash the "important" parts of PE files. After rigorous experimentation we discovered these changes were sufficient to get identical hashes (and thereby signatures) on Windows and Wine. -- v13: imagehlp: Fix ImageGetDigestStream. Add test case for image with rsrc/reloc sections https://gitlab.winehq.org/wine/wine/-/merge_requests/10295
