space-wine

space-wine is an upstream-first Wine patch queue with deterministic standalone verification. The repository is organized to make subsystem review, revision rounds, and cross-version evidence easy for Wine maintainers to evaluate.

Baselines and Scope

Role	Upstream tag	Default install prefix	CI scope
Primary baseline	wine-11.5	/opt/wine-11.5	Windows ground truth, Linux patched/unpatched, macOS patched
Backport baseline	wine-10.0	/opt/wine-10.0	Windows ground truth, Linux patched/unpatched

There is no earlier maintained 11.x review target. 11.5 is the only primary line in scope.

Upstream Submission Surface

Primary reviewer-facing paths:

• patches/README.md: subsystem queue and status table
• UPSTREAMING.md: expected Wine review flow and submission rules
• BUILDING.md: baseline-specific build instructions
• tests/: standalone verification tools

Secondary material remains under support/, but it is not part of the primary upstream case.

Patch Groups

Upstream candidates

• ntdll: contested file-lock completion
• kernelbase: UnlockFileEx event completion
• win32u: OEM charset mapping
• user32: stale multiline edit line-list rebuild
• comctl32_v6: stale multiline edit line-list rebuild
• wineserver: released lock FD cleanup
• kernel32/tests: lock and unlock coverage expansion

Local-only workarounds

• wow64cpu: Rosetta 2 workaround for the macOS 11.5 line only

Review Status Model

Every queued patch is classified in patches/README.md with:

• subsystem
• baseline applicability
• upstream status
• deterministic test coverage

Status values:

• ready: suitable for subsystem review as-is
• needs split: behavior is promising but should be divided before review
• needs stronger evidence: deterministic tests/native comparison should be improved
• backport only: carried only to keep the 10.0 line aligned
• local-only: not intended for upstream submission

Verification Contract

• Windows ground truth runs the standalone tools on real Windows kernels.
• Linux CI compares patched and unpatched 10.0 and 11.5.
• macOS CI validates the patched 11.5 line.
• Local verification writes generated output under build/results/.

Standalone tools:

• locktest.exe: parameter handling, APC, IOCP, and lock semantics
• lockstress.exe: contested overlapped lock completion
• fonttest.exe: OEM charset regression coverage
• edittest.exe: multiline edit-control stability
• fdleaktest.exe: released lock FD regression coverage

Quick Start

# Primary baseline
make prove

# Backport baseline
make prove WINE_VERSION=10.0

The Makefile clones the selected upstream tag, applies the appropriate patch and workaround series, builds Wine, and runs the standalone verification suite.

Notes for Reviewers

• The primary implementation line is wine-11.5.
• The backport line is wine-10.0.
• The patch queue is intentionally structured around subsystem review and revision rounds.
• Local-only workarounds are separated from upstream candidates.
• Application-specific collateral is archival and not required to evaluate the fixes.
