Unreleased

  • Native Windows source and development builds invoke Nix through WSL2. The hook translates paths, builds the requested non-Apple target, copies the library back, and retains source mode's pinned hash verification. The optional wsl_distribution user define selects a distribution; otherwise the default is used. verify_release, and update_lock for packages without Apple targets, also work from Windows through WSL2. This changes only the Dart build runner; Nix recipes, native sources, and expected library hashes are unchanged.

  • Source builds resolve the flake from the package directory, supporting parent paths containing #. Windows source dependencies with non-ASCII filenames are tracked correctly.

  • Three more Windows targets beside x86_64-pc-windows-msvc: x86_64-pc-windows-gnullvm and aarch64-pc-windows-gnullvm build with zig's MinGW-w64 toolchain, for C and C++ dependencies that need GCC-style flags, and aarch64-pc-windows-msvc with the SDK's arm64 libraries. A package lists the ABI it ships per architecture; the hook serves a Windows build from whichever is listed, and from the MSVC one when both are. The SDK is now fetched for both architectures, so a toolchains.xwin override needs the hash of such a splat.

  • rust.cflags keys must be listed targets; flags for a target the package no longer builds are an error rather than silently ignored.

  • A CMake build on a Windows target can compile resource scripts: the llvm-rc on its path has a clang for its preprocessing.

  • zig compiles C without its debug-mode sanitizer. A library whose C was compiled with no optimisation level changes bytes; one compiled with -O1 or higher does not.

  • The default iOS floor is 13, the version Flutter 3.47 asks native assets for. With the former default, 15, the hook refused every iOS build. A package that kept the default gets new iOS bytes with this version: run dart tool/update_lock.dart, commit the lock, and the default branch publishes the new release. The floor error now says what to change.

  • The Windows host in CI loads every x64 Windows library the package lists, resolving imports against Windows' own DLLs only, before anything is released; a library that fails to load fails the run with the reason. Each host job may run for four hours instead of two.

  • The workflows pin every action to a commit, the publishing job's included.

  • bindgen loads libclang from the pinned LLVM. A crate that generates bindings no longer fails to build on Linux, where the sandbox has no libclang, nor depends on the Mac's Xcode or Command Line Tools on macOS.

  • A library built on macOS is now byte-identical to the same library built on Linux. Three things differed by build host, and each change below can alter a package's bytes once; run dart tool/update_lock.dart after updating dnix:

    • Cargo resolved build scripts' and proc macros' dependencies for the machine running the build, so a dependency that only one host's platform needs changed the symbol hashes of everything above it. A platform condition in a vendored manifest that holds on some build hosts and not on others now holds on all of them for build-time dependencies; what the library itself links is unchanged.
    • LLVM sorts some lists with the C library's qsort, and glibc and macOS order equal elements differently, which changed instruction order and the names of promoted symbols on ARM targets. rustc runs with a qsort that is glibc's merge sort on every host, and a build stops if rustc did not load it.
    • bindgen ran Xcode's clang on macOS, and none on Linux, to find header directories, so the same header gave different bindings. It now runs the clang that belongs to the pinned libclang, and Android builds hand it the NDK's sysroot.

  • A target keeps only its dynamic library, the file the lock records and the hook ships. A static library or import library the crate also builds is no longer in the build output, the CI artifacts, or SHA256SUMS; its member names and debug info carry the build directory and toolchain paths, so it could not be compared across machines.

0.1.0

  • Initial release, extracted from frostdart: the build hook with its prebuilt, source, and dev modes; the Nix environment and Rust driver; the Apple build through a pinned Xcode; the reusable workflow that verifies every push on four hosts and publishes releases; and the tools that update the lock and verify a platform.
  • dnix.lock is a source file written by update_lock: it records what the native source builds to and names the release, derived from the hashes, that holds those bytes. CI fails when the source and the lock disagree and publishes the release from the default branch.
