Dry Ark Wintun Fork

This repository is a fork/mirror of upstream Wintun focused on reproducible userspace builds and downstream packaging for py-tuntap-abi3.

Why this fork exists

• Keep the non-driver (.dll) portion buildable from open source in a repeatable GitHub Actions pipeline.
• Publish architecture-specific artifacts so downstream projects can ship only what they need.
• Support efficient Python wheel packaging by avoiding "all architectures in every wheel."

What this fork builds and publishes

For each tagged release (for example v0.14.1-dryark.18), CI publishes:

• drywintun-<upstream-version>-x64.zip
• drywintun-<upstream-version>-arm64.zip
• drywintun-<upstream-version>-x86.zip
• wintun-<upstream-version>.zip (upstream reference package from wintun.net)

Each drywintun-*.zip bundle contains one architecture's files:

• drywintun-<arch>.dll (built in this repository)
• DRYWINTUN-<ARCH>.sys (extracted from upstream binary resources)
• DRYWINTUN-<ARCH>.inf (extracted from upstream binary resources)
• DRYWINTUN-<ARCH>.cat (extracted from upstream binary resources)

What this accomplishes for Python wheels

Downstream wheel builders can fetch a single bundle per target architecture and include only:

• x64 Windows wheel -> x64 bundle
• arm64 Windows wheel -> arm64 bundle
• x86 Windows wheel -> x86 bundle

That keeps wheels architecture-specific and avoids wasting space by shipping unnecessary architectures.

Build and release model

• Workflows run on GitHub-hosted windows-2022 runners.
• Tags matching v<major>.<minor>.<patch>-dryark.<n> trigger release publication.
• The fork builds drywintun.dll from source.
• The workflow also fetches the corresponding upstream wintun-<version>.zip and extracts per-arch driver sidecars.

Scope and intent

This fork is for transparent build/release automation and downstream packaging ergonomics. It is not presented as a replacement source of truth for upstream Wintun development.

Licenses

• Source code in this repository follows upstream licensing terms (see COPYING and upstream notices).
• Upstream prebuilt binaries from wintun.net are provided under their own distribution terms in the upstream package.
