FreeBSD, big-endian, and many new architectures

This release finally includes FreeBSD in the list of supported operating systems. That should make it much easier to port DwarFS to other *BSDs as well. Big-endian platforms are also supported, and the file system images (which use little-endian) are fully portable between architectures. Binary releases are now available for a wide range of architectures: aarch64, arm, i386, loongarch64, ppc64, ppc64le, riscv64, s390x, and x86_64.

Metadata manipulation

Before this release, file system metadata was immutable once a DwarFS image had been created, and the only way to manipulate metadata was to build a new image from scratch. This release adds two options to mkdwarfs:

• --rebuild-metadata allows changes/upgrades to the metadata block. This makes it easy to change how the metadata is packed, or even perform manipulations such as --chmod after the fact.
• --change-block-size allows you to change the physical block size of the file system image.

Bug fixes

• The linker configuration for the release binaries was broken. The symptom was that, very occasionally, tests would fail in CI with std::terminate being called after the exception handling code failed to unwind the stack. The root cause was that, in clang builds, code from libunwind and libstdc++ was arbitrarily mixed, which—depending on the order in which individual threads were scheduled in the unit tests—could lead to stack unwinding working flawlessly or not at all. This was one of the hardest bugs to track down this year; fortunately, the fix was quite simple. It’s possible this issue is present in previously released binaries, although there have been no reports.

• Made section index discovery more robust. Fixes #264.

• A recent kernel change (LKML thread, 2025-05-05) caused tools_test to fail on Linux 6.14 and later. This has been fixed by accepting both EPERM and ENOSYS as valid error codes for link() calls.

Features

• FreeBSD support. Everything that works on Linux should also work on FreeBSD. No static binaries are provided for FreeBSD, but the build should work out of the box once all dependencies are installed.

• Big-endian architectures. This is still experimental, even though all unit tests pass under QEMU and the benchmark suite runs on real hardware. This currently requires forked versions of folly and fsst. The changes are small, and the pull requests will hopefully be merged upstream soon. (facebook/folly#2484, cwida/fsst#36)

• Experimental 32-bit support. While DwarFS should largely “just work” on 32-bit with small images (a few hundred megabytes), limited address space is a problem due to DwarFS’s extensive use of memory-mapped files. There will be changes to limit the use of mmap in the future (primarily due to other issues), which should improve 32-bit compatibility as a side effect. Fixes #268.

• Wider CPU architecture coverage. Static binary releases (including universal binaries) are now available for x86_64, aarch64, i386, arm, ppc64, ppc64le, riscv64, s390x, and loongarch64. Building the new release binaries uncovered a few bugs in clang (llvm/llvm-project#150913), binutils (https://sourceware.org/bugzilla/show_bug.cgi?id=33223), mold (rui314/mold#1490, rui314/mold#1496, rui314/mold#1497, rui314/mold#1498), and UPX (upx/upx#925), not all of which have been fixed. As a result, the binaries use slightly different toolchains and configurations depending on the architecture. Fixes #266, #268.

• Custom self-extracting stub for universal binaries. It aims for simplicity and portability and should work on most Linux systems. It is used if UPX support for an architecture is unavailable, or if the binaries extract much faster than the UPX-compressed version. The stub also supports --extract-wrapped-binary <file> to extract the embedded binary.

• Category metadata stored by default. The category metadata for categorized blocks is now stored in the metadata block by default. This allows recompressing blocks with a metadata-dependent algorithm (e.g., FLAC) even if they were previously compressed with a metadata-independent algorithm. You can disable this with --no-category-metadata. See the mkdwarfs man page for details.

• Options for smaller metadata. The --no-category-names and --no-category-metadata options can be used to reduce metadata size. However, this makes it impossible to use metadata-dependent compression algorithms (e.g., FLAC) or to select category-specific compression when recompressing the image.

• Metadata rebuilding in mkdwarfs. In addition to recompressing, it is now possible to change metadata packing and apply operations such as --set-owner, --set-group, --set-time, --time-resolution, --chmod, or --no-create-timestamp. Note that these operations are potentially lossy and may be irreversible. By default, the history of metadata rebuilds is tracked in the metadata itself; you can disable this with --no-metadata-version-history.

• Change block size on existing images. You can now change the block size of an existing image using --change-block-size. This implies --rebuild-metadata and --recompress=all and can be useful for tuning performance without recreating the image from scratch.

• Runtime memory display in mkdwarfs. mkdwarfs now shows its current memory usage while running. Note that -L/--memory-limit still only limits the memory used for the block queue, not overall memory usage. Fixing this is on the roadmap; there’s no need to file an issue.

• dwarfsextract format controls. New options --format-options and --format-filters control the output format. There is also --format=auto to automatically “guess” the format and filters based on the output file name. (Thanks to @oxalica for the pull request.)

• dwarfsck detail level. New frozen_details detail level shows frozen_analysis content ordered by memory location instead of memory usage, and also shows the address range of each section.

• Lean LRU cache. Replaced folly’s EvictingCacheMap with a simple in-repo LRU cache implementation. This reduces external dependencies and binary size without sacrificing performance.

• Windows extended attributes. The pxattr utility now supports all extended attribute operations on Windows, including setxattr() and removexattr(). Error handling and reporting for extended attributes on Windows has also been improved.

Docs

• Updated dwarfs-format.md with more information on section types, compression metadata, and the Frozen2 binary metadata layout. (Thanks to @oxalica for asking the right questions, reporting bugs, and ultimately releasing a Rust library to read/write DwarFS images.)

• Added a notable users section to the README. (Thanks to Vitaly Zdanevich for the PRs.)

• Updated mkdwarfs docs with more information on worker threads and the requirements for bit-identical images.

• Major README overhaul: added a Quick Start section, added more links, and fixed typos and wording.

74b730031dfe4d4aa0caaa411ea806d02ba44f32dc2618e52739ce7...

This release mainly fixes a bug that was introduced with v0.12.0 (06f8728 to be precise). When re-compressing a file system image where some blocks cannot be compressed using the selected algorithm because of a bad_compression_ratio_error (i.e. when the compressed size is actually larger than the uncompressed size), the resulting block object was left empty, which subsequently led to a segfault.

A few small bugs have also been fixed and couple of features were added to the dwarfsck tool, mostly triggered by the discussion in #263.

Most other changes that made it into the release were related to how the static binaries are built. All the dependencies have been updated, in particular also for the Windows build. The Windows build was also switched from openssl to libressl. Overall, the size of the Windows universal binary was reduced by 30% and is now comparable in size to the Linux binaries.

Bugfixes

• Segfault on bad_compression_ratio_error. When recompressing a filesystem where some blocks cannot be compressed using the selected algorithm because of a bad_compression_ratio_error, the resulting block was left empty after the refactoring done in 06f8728.
• Add history unless --no-history is given when rewriting a file system image.
• Allow dumping frozen_layout w/o frozen_analysis in dwarfsck.
• Logging timestamps should show local time.
• Workaround a weird MSVC bug.
• Remove useless cast causing compiler warning.

Features

• More complete breakdown of metadata in dwarfsck.
• Add schema_raw_dump flag to dwarfsck --detail.

Build

• Switch static build to libressl on Windows.
• Update static build libraries.
• Update folly/fbthrift/fsst.

Other

• Introduce and use safe_localtime() to prevent issues with fmt deprecating fmt::localtime.
• Speed up a few slow tests on Windows.

This release provides a fix for cases where automatic image offset detection could fail to work correctly as well as further size optimizations of the release binaries. The dwarfs-universal binary now uses LibreSSL's libcrypto, whereas the binaries from the release tarball use OpenSSL's libcrypto. This is a trade-off favoring size for the universal binary and speed for the "regular" binaries. Note, however, that this will be imperceptible unless you use dwarfsck with either --check-integrity or --checksum.

Bugfixes

• Automatic image offset detection (for images using a custom header) did not work correctly if the header contained a string that would be identified as the start of a v1 section header (these were only used before dwarfs-0.3.0). If there was either "DWARFS\x02\x00" or "DWARFS\x02\x01" in the header, offset detection would fail. The check has been modified to peek further into the data and ensure this really is a v1 section header, and also checking if the next section header position can be derived from the length field. It is still possible to construct a file system image where offset detection will ultimately fail, but it is much less likely with the change.

Build

• The build process for the release binaries has been further tweaked to reduce binary size. The dwarfs-fuse-extract binary now again supports extracting files by pattern; I didn't realize that this was actually a widely used feature before dropping it in the last release. dwarfs-universal is now linked against LibreSSL's libcrypto instead of OpenSSL's. This significantly reduces the size at the expense slightly slower cryptographic hash functions. However, this will likely only be perceivable when using --tool=dwarfsck with either --check-integrity or --checksum. The binaries from the release tarballs are still linked against libcrypto from OpenSSL.

This release provides a fix for a performance regression, switches the default memory allocator back to jemalloc, and further reduces the size of the dwarfs-fuse-extract binary. The latter is available as both a jemalloc and a mimalloc version. jemalloc offers a lot more configuration options that can be crucial in optimizing the memory profile of e.g. the FUSE driver. If you don't need that flexibility, you can save a few bits by using the -mimalloc version.

Bugfixes

• The dwarfs-0.12.0 release introduced a performance regression where FLAC compression took more than twice as long as in the previous releases. This has been fixed. FLAC decompression was unaffected.

Build

• A few small refactoring changes to further reduce the size of the fuse-extract binary. In particular, the performance monitor and the history feature are now fully removed. Also, the functionality to extract in different archive formats as well as to extract only files matching a pattern have been removed, so the image can only be fully extracted to disk.

A quick update to v0.12.0 that addresses a few issues and improves the performance of the release binaries while mostly making them even smaller. The universal x86_64 binary is slightly bigger, but that's a different story [1].

Bugfixes

• Attempt to fix a linking issue in the Homebrew build.

Features

• Added --memory-limit=auto to mkdwarfs to use a more reasonably (hopefully) default for the block queue. The old default of 1 GiB was quite arbitrary and definitely not suitable for low-end systems. The new auto default will determine the limit based on the number of workers (which in turn is based on the number of CPUs), the block size, and the amount of physical memory of the system.

• Replaced vector_byte_buffer with malloc_byte_buffer, which is internally based around a simple buffer that doesn't incur the cost of initializing each element like std::vector. Especially for large blocks which are known to be overwritten immediately, this can save a few CPU cycles.

• The x86_64 release binaries now use an optimized memcpy implementation (if supported by the CPU) instead of the rather slow musl memcpy implementation. This makes mkdwarfs a few percent faster and dwarfsextract up to 20% faster.

Build

• Switched the release binaries to use mimalloc instead of jemalloc. The primary reason for this change is a reduction in binary size.

• Updated the xz library to the latest 5.8.1 release.

[1] I've noticed that the universal binary, and sometimes the other binaries as well, fluctuate dramatically in size after being UPX compressed. In the last CI build before tagging the new DwarFS release, the UPX-compressed universal binary had a size of 2,713,752 bytes. The only change after tagging the release was the version info (although, with LTO, you never know what the compiler makes of that). Interestingly, when unpacked, both binaries have exactly the same size. But the packed size differs by ~190 KiB.

The main features of this release are new licensing conditions and significantly smaller binaries.

New Licensing Conditions

Instead of being all GPL-3.0 like all the previous releases, this release changes the license of a large fraction of the DwarFS code to MIT. All tools and libraries that only read DwarFS images are now MIT-licensed. Everything else (e.g. mkdwarfs) is still GPL-3.0 for the time being.

Significantly reduced binary size

By moving the build pipeline to Alpine Linux and through some major refactoring, the size of the release binaries has been reduced significantly.

There's now also an additional binary called dwarfs-fuse-extract that combines the functionality of the FUSE driver dwarfs and dwarfsextract in a single, extremely small binary:

The main use case for this binary is single-file application image runtimes (e.g. uruntime). This binary doesn't have built-in manual pages or support for the performance monitor. It also only supports zstd and lzma compression.

Bugfixes

• Build release binaries against an up-to-date libfuse. Fixes github #252.

• Changes for compatibility with Boost.Process v2.

Features

• Re-licensed all libraries required for reading DwarFS images under the MIT license. The source of all tools that just read DwarFS images (i.e. everything except for mkdwarfs) are also under the MIT license now. Everything else is still GPL-3.0. Addresses github #255.

• Significantly reduced binary size in the static release builds. This is the result of refactoring code that unconditionally pulled in code-heavy dependencies such as libcrypto, as well as optimizing the build pipeline (e.g. building dependencies with only the necessary set of features) and turning on link time optimization.

• A new kind of "universal" binary dwarfs-fuse-extract is part of the release now. This combines the FUSE driver (dwarfs) and dwarfsextract into a single binary, but does not include the mkdwarfs and dwarfsck tools that are also part of the regular universal binary. dwarfs-fuse-extract is much smaller than the regular universal binary and especially suitable to AppImage-like applications.

• New hotness categorizer in mkdwarfs that allows a list of "hot" files to be stored in distinct file system blocks.

• New explicit ordering mode in mkdwarfs that allows files to be ordered accoring to the order in a given list file.

• dwarfs now shows the version of the FUSE library used.

• New dwarfs options preload_all and preload_category to populate the block cache immediately after mounting.

• New dwarfs option analysis_file that can be used for profiling and as input to mkdwarfs new hotness categorizer and explicit ordering mode.

• New dwarfs option block_allocator that allows the user to switch from a malloc-based block allocator to an mmap-based one. This can help with returning memory back to the system if the blocks are evicted from the cache.

Bugfixes

• macOS Ventura's version of clang appears to be missing an implementation of std::hash<std::filesystem::path, making it hard to define an unordered_map<filesystem::path>. Work around by simply using an unordered_map<string> instead.
• Installing the binaries using cmake did not honor the CMAKE_INSTALL_BINDIR or CMAKE_INSTALL_SBINDIR variables. Fixes github #253.

Bugfixes

• macOS Ventura's version of clang appears to be missing the <source_location> header, despite Apple claiming otherwise. Fix this by shipping a wrapper and providing a fallback implementation.

Bugfixes

• Remove the access implementation from the FUSE driver. There's no point here trying to be more clever than FUSE's default. This makes sure DwarFS will behave more like other FUSE file systems. See github discussion #244 for details.
• Limit the number of chunks returned in inodeinfo xattr. Highly fragmented files would have megabytes in inodeinfo, which not only breaks the xattr interface, but can also dramatically slow down tools like eza who like to read xattrs for no apparent reason.
• Avoid nested indentation in manpages to work around ronn-ng bug. Fixes github #249.
• Don't link library against jemalloc. This fixes both issues with pydwarfs and issues building with jemalloc support on macOS. Only the binaries are now linked against jemalloc, which should be sufficient.

Features

• Support case-insensitive lookups. Fixes github #232.
• Allow setting image size in FUSE driver. Fixes github #239.
• Support extracting a subset of files with dwarfsextract using the new --pattern option. The same glob patterns can be used as for the filter rules in mkdwarfs. Fixes github #243.
• Allow overriding UID / GID for the whole file system when using the FUSE driver on non-Windows platforms. See github discussion #244.
• Expose more LZMA options (mode, mf, nice, depth).
• Improve filter patterns, which now support ranges and complementation.
• Improve speed of filesystem walk / walk_data_order calls by 80% / 40%. The impact of this will largely depend on what the code is being run for each inode, but, for example, the speed of listing more than 14 million files with dwarfsck will take about 16 seconds compared to 17 seconds with the previous release.
• Added an inode size cache to the metadata to speed up file size computation for large, highly fragmented files. The configuration is currently fixed using a conservative default. Only files with at least 128 chunks will be added to the cache, so in a lot of cases this cache may be completely empty and not contribute to the size of the file system image at all.
• Use bit-packing for hardlink, shared files, and chunk tables. This will consume less memory when loading a DwarFS image.
• Show total hardlink size in dwarfsck output.
• Library: return a dir_entry_view from readdir and find. This is more consistent, but was previously not easily possible due to the lack of a "self" dir entry in the metadata. The "self" entry has been added and will only impact the size of the metadata if directories metadata is not packed.
• Library: prefer std::string_view over char const*.
• Library: add directory iterator to directory_view.
• Library: support for maxiov parameter in readv call.

Other

• Lots of internal refactoring to improve overall code quality.
