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.
download --with-dxsdk fetches the DirectX SDK (June 2010) - the last
standalone release of D3DX9/10/11, XInput and XAudio2, dropped from
the Windows SDK entirely once D3DX was deprecated, but still needed
by plenty of legacy code. Like the WDK, it isn't part of the VS
installer manifest, so this is its own self-contained fetch+unpack
path: the installer is a self-extracting CAB, unpacked directly via
cabextract (already a prerequisite for the WinSDK .msi payloads) with
its -F filter restricting extraction to just Include/ and Lib/ -
about 21MB out of the installer's 1.2GB uncompressed payload.
Verified against the real installer: real d3dx9.h and d3dx9.lib
(x86 and x64) extracted correctly and linked into an actual legacy
game client build.
Found via manual audit plus a staticcheck run:
- collectDependencyClosure iterated a package's dependencies map
directly, so which package "won" a same-key collision (and the
order things got downloaded/unpacked in) could vary between runs
of the exact same download command. Sort the dependency targets
first, matching what --print-deps-tree's tree-printer already did.
Verified two consecutive --print-deps-tree runs now produce
byte-identical output.
- HTTP retry loops (manifest fetch, payload download) retried
immediately with no backoff, which just hammers a server harder
during exactly the kind of transient failure retries exist for.
Added a capped exponential backoff (1s/2s/4s/8s/10s).
- --architecture/--host-arch accepted any string silently; a typo'd
value matched nothing during package selection and surfaced as a
confusing downstream failure far from the actual mistake. Now
rejected up front with a clear error.
- pumpLines' bufio.Scanner silently stops (dropping the rest of a
tool's output) if a single line ever exceeds its buffer - narrow but
real for pathological cases like heavily templated C++ diagnostics.
Now at least reports that truncation happened instead of losing
output with no trace.
- Removed select.go's unused off() helper (staticcheck U1000).
Re-verified end-to-end after these changes: a real KMDF driver build
and a plain cl/link build both still succeed.
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.
