v0.12.9

Added

• TPKG_FORMAT_RUNTIME (format_id 4): a runtime payload slot in the tpkg manifest — fat three-part packages (bootstrap + runtime payload + images) validate as well-formed; vendored into tebako and tebako-bootstrap from this header.
• linux-musl-arm64 release leg (prebuilt libtfs + deps + mkdwarfs + tebakofs for musl/arm64) — enables the runtime-ruby musl-arm64 matrix and tebako prebuilt flows on arm64 Alpine.

Changed

• Release notes corrected for the current build/link reality (gnu legs in the ubuntu-20.04 ci container with static C++ runtime; musl legs static C++ runtime + shipped toolchain archives).

Release artifacts

Per-platform packages (platform ids: linux-gnu-x86_64, linux-gnu-arm64,
linux-musl-x86_64, linux-musl-arm64, macos-arm64, macos-x86_64,
windows-ucrt64):

• libtfs-<version>-<platform>.tar.gz (.zip on Windows):
  • lib/libtfs.a — the libtfs static library
  • lib/libtebako_dirent_helper_c.a — C helper archive (link dependency
    of libtfs where the legacy tebako API is built; not shipped on Windows)
  • include/tebako/** — public headers
  • lib/cmake/libtfs/ — CMake package config (find_package(libtfs))
• libtfs-deps-<version>-<platform>.tar.gz (all platforms): the
  transitive static libraries consumers link against —
  libdwarfs_reader, libdwarfs_common, libdwarfs_metadata_legacy,
  libdwarfs_decompressor, libflatbuffers, libzip, libfmt,
  libxxhash, libzstd, liblz4, liblzma, brotli (dec/enc/common),
  libz, libbz2, libboost_filesystem, libboost_chrono, plus
  libcrypto/libssl on Linux and Windows (macOS consumers link
  brew/system OpenSSL at link time) — with the CMake package configs
  of those ports under share/ (or lib/cmake/ where a port installs
  there), so find_dependency can still resolve, and a curated
  header set under include/ (brotli/, zstd.h/zstd_errors.h/
  zdict.h, lz4*.h, lzma.h + lzma/, zlib.h/zconf.h,
  bzlib.h, fmt/, flatbuffers/, zip.h/zipconf.h,
  xxhash.h/xxh3.h, plus the boost_filesystem/boost_chrono
  subset of boost/), so consumers can also compile against the
  shipped archives (e.g. native gem extensions that include
  <brotli/encode.h>).
• mkdwarfs-<platform> and tebakofs-<platform> — command-line tools
  (.exe suffix on windows-ucrt64)

Self-contained consumption: a libtfs-<version>-<platform>
package plus the matching libtfs-deps-<version>-<platform> package
are fully self-contained — compiling and linking against libtfs.a
needs no vcpkg (and no C++20 dependency build) on the consumer
machine, only a compiler, a linker and the platform system libraries
(plus brew/system OpenSSL on macOS).
Consumers that prefer to resolve dependencies themselves (e.g. their
own vcpkg) can keep using the libtfs package alone.

Linkage notes (from the shipped binaries' ldd/objdump output):

• All C/C++ third-party dependencies (dwarfs-t, libzip, fmt, Boost, …)
  are statically linked into the binaries on every platform.
• linux-gnu-*: dynamic glibc only (built inside the tebako
  ubuntu-20.04 ci container; libstdc++/libgcc linked statically —
  runs on any glibc ≥ 2.31 system such as Ubuntu 20.04+).
• linux-musl-*: dynamic musl libc only (built on Alpine 3.21;
  libstdc++/libgcc linked statically — runs on any musl system,
  including tebako's older alpine-3.17 containers). The musl deps
  packages additionally carry the build's libstdc++.a/libgcc.a/
  libgcc_eh.a so consumers on older toolchains can still close
  the static link.
• macos-*: dynamic macOS system libraries only (libSystem, libc++;
  built on macos-14 / macos-15-intel).
• windows-ucrt64: dynamic UCRT + MSYS2 runtime DLLs
  (libgcc_s_seh-1.dll, plus libwinpthread-1.dll/libstdc++-6.dll
  for mkdwarfs); run inside MSYS2 UCRT64 or ship those DLLs alongside.

The Windows package ships the modern C/C++ API only (the legacy tebako
API needs the ruby build context).

SquashFS: shipped artifacts are built WITH_SQUASHFS=OFF — the
backends are dwarfs + zip only, so consumers are not forced to link
LGPL squashfs-tools-ng. POSIX source builds may opt into the SquashFS
backend (LGPL) with -DWITH_SQUASHFS=ON.
