combineDirTrees' merge logic assumes it's the only thing moving files
into a given target at a time; two `vintner download`/`install` runs
racing against the same --dest could otherwise interleave os.Rename
calls and corrupt the tree instead of erroring cleanly. Take an
exclusive, non-blocking flock(2) on the destination for the duration
of each run, so a second invocation fails immediately with a clear
message instead of silently colliding with the first.
vintner only ever downloads one compiler generation, but real-world
.vcxproj files are pinned to whichever PlatformToolset they were last
saved under - v142 (VS2019) for anything not actively maintained is
extremely common. MSBuild checks toolset "installed-ness" (MSB8020) by
testing whether MSBuild/Microsoft/VC/v<schema>/Platforms/<arch>/
PlatformToolsets/<toolset>/ exists on disk - a plain file lookup our
downloaded MSBuild package only satisfies for the exact generation it
shipped. `install` now symlinks every historical numeric PlatformToolset
name (v90 through v143) onto whichever real toolset directory is
actually present, so any of them resolves transparently; Toolset.props/
.targets don't hardcode a version number, so aliasing is correct, not
just a workaround.
Three more MSBuild property/environment issues came with it, all found
building a real years-old project against the one modern toolchain
vintner installs:
- VCInstallDir_<N>/VCToolsInstallDir_<N> needed a third numbering
source (PlatformToolset short names from Microsoft.VCToolsVersion.
v<N>.default.props) alongside the existing MSBuild schema-version and
known-toolset lists, so the env-var-driven half of toolset resolution
covers the same names the on-disk alias does.
- VCToolsVersion must be a real version string: left unset, it falls
back to a literal placeholder that then hits an unconditional
version-string comparison elsewhere in Microsoft.CppBuild.targets
(MSB4184). Setting it to the real installed version in turn requires
CheckMSVCComponents=false, since CheckVCToolsetVersion (MSB8052)
otherwise rejects an aliased PlatformToolset whenever its numeric
generation doesn't match VCToolsVersion's - exactly the case aliasing
creates on purpose. Everything else CheckMSVCComponents gates is
diagnostic-only (MFC/ATL/Spectre presence warnings), so disabling it
costs nothing else.
- WindowsTargetPlatformVersion needed to become an explicit /p: global
property on the msbuild command line, not just an env var: legacy
.vcxproj files commonly hardcode this in a PropertyGroup, and an
explicit project assignment always wins over an inherited environment
variable of the same name. A command-line global property is the one
thing a project file can't override. Only injected when the caller
hasn't already pinned it themselves.
Renamed the GitHub repo, Go module path, binary, and default install
directory from msvc-go-wine to vintner. Updated every user-facing
string (usage text, error prefixes, README, LICENSE, CI/release
workflow) and the embedded compatibility patches' own header text to
match; the VINTNER_LANG env var replaces VSMC_GO_WINE_LANG.
Also fixes a real bug found while re-verifying the rename end-to-end:
Microsoft.Cpp.WindowsSDK.props.patch had LF-only line endings in its
hunk body while the real Microsoft-shipped file it targets is CRLF,
so `git apply` silently failed on every real install and the SDK
detection fix it's meant to provide was never actually taking effect.
Restored matching CRLF endings in the hunk (checked against the other
five patches, which already had this right). Left the patch's
internal MsvcGoWine_ExtraSdkRoots MSBuild property name alone rather
than renaming it too - changing hunk content, even just an identifier,
breaks reverse-apply idempotency for anyone re-running download
against an already-patched tree, which the fix above depends on. Added
a .remove marker so an existing install's old-named props file gets
cleaned up on the next download.
Re-verified end-to-end after the rename: general MSBuild/cl/link
still work, and a real KMDF driver build (compile, link, INF stamping,
Inf2Cat signability check) still succeeds under the renamed binary.
README also gets an accuracy pass: WDK support and the download/env
CLI flags it lists were out of date (WDK was previously listed under
"Known gaps" despite being implemented and verified), the full tool
list was missing mc/cmd/findstr, and the new command aliases and
VINTNER_LANG option are now documented.
A single-binary Go tool for cross compiling with the real MSVC toolchain
on Linux via Wine. Behaves as cl/link/lib/rc/midl/mt/dumpbin/msbuild/
nmake/ml/ml64/armasm/armasm64/cmd/findstr depending on the name it's
invoked as, plus download/install/env/version management subcommands.
- download: fetches the MSVC/WinSDK installer manifest, resolves package
selection and dependencies, downloads and verifies payloads, unpacks
VSIX/MSI packages, and applies a handful of compatibility patches so
VsDevCmd.bat and MSBuild's SDK detection work without a Windows
Registry (which doesn't exist under Wine).
- install: locates the installed toolchain/SDK versions, normalizes
header/library name casing, lays out per-architecture tool symlinks
with an env.json config each, and compiles a small native launcher
(toolrelay.exe) that lets mt.exe's CMake-compatibility exit code
survive Wine's own exit-code truncation.
- The wrapper runtime rewrites absolute unix paths in tool arguments into
Wine's z:\... form, runs the real .exe under wine, and rewrites the
tool's output back to plain unix paths.
Verified end-to-end against a real MSVC/WinSDK download: cl, link, mt and
the resulting hello.exe all work under Wine, including through the
toolrelay.exe relay path and with paths containing non-ASCII characters.
Offline unit tests cover the wrapper's path-rewrite/output-filter logic,
install-time header lowercasing, and download package-selection/
dependency-resolution.
