v0.12.8

Fixed

• dwarfs-t tebako-v0.14.1-18 (same tree as -17): directory streams synthesize . and .. (POSIX readdir semantics) — packaged ruby's Dir.read contract (tebako patches-dir test) holds on libtfs images.
• dwarfs port: USE_JEMALLOC=OFF — consumers no longer inherit a shared jemalloc reference (brew dylib leak into tebako packaged binaries on macOS).

Changed

• dwarfs overlay port: tebako-v0.14.1-18 (identical content to -17; renamed after a vcpkg asset-cache poisoning by a propagation-lag download).
• musl deps packages now also ship the build's libstdc++.a/libgcc.a/libgcc_eh.a so tebako's musl link resolves the dep set's references (e.g. _M_replace_cold from libstdc++ >= 13) on older-toolchain containers (tebako alpine-3.17, gcc-12); musl release legs stay on alpine:3.21 with musl-native cmake (the xpack cmake is a glibc binary and cannot run on musl).

Release artifacts

Per-platform packages (platform ids: linux-gnu-x86_64, linux-gnu-arm64,
linux-musl-x86_64, 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,
  jemalloc, Boost, …) are statically linked into the binaries on
  every platform.
• linux-gnu-*: dynamic glibc/libstdc++ (built on ubuntu-24.04;
  requires glibc ≥ 2.38 at runtime, e.g. Ubuntu 24.04 or newer).
• linux-musl-x86_64: dynamic musl libc + libstdc++/libgcc_s (built
  on Alpine 3.21; on a minimal Alpine install: apk add libstdc++ libgcc).
• 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.
