The API and ABI are still backward compatible with liblzma 5.2.x and 5.0.x. Since 5.3.5beta: * All fixes from 5.2.10. * The ARM64 filter is now stable. The xz option is now --arm64. Decompression requires XZ Utils 5.4.0. In the future the ARM64 filter will be supported by XZ for Java, XZ Embedded (including the version in Linux), LZMA SDK, and 7-Zip. * Translations: - Updated Catalan, Croatian, German, Romanian, and Turkish translations. - Updated German man page translations. - Added Romanian man page translations. Summary of new features added in the 5.3.x development releases: * liblzma: - Added threaded .xz decompressor lzma_stream_decoder_mt(). It can use multiple threads with .xz files that have multiple Blocks with size information in Block Headers. The threaded encoder in xz has always created such files. Single-threaded encoder cannot store the size information in Block Headers even if one used LZMA_FULL_FLUSH to create multiple Blocks, so this threaded decoder cannot use multiple threads with such files. If there are multiple Streams (concatenated .xz files), one Stream will be decompressed completely before starting the next Stream. - A new decoder flag LZMA_FAIL_FAST was added. It makes the threaded decompressor report errors soon instead of first flushing all pending data before the error location. - New Filter IDs: * LZMA_FILTER_ARM64 is for ARM64 binaries. * LZMA_FILTER_LZMA1EXT is for raw LZMA1 streams that don't necessarily use the end marker. - Added lzma_str_to_filters(), lzma_str_from_filters(), and lzma_str_list_filters() to convert a preset or a filter chain string to a lzma_filter[] and vice versa. These should make it easier to write applications that allow users to specify custom compression options. - Added lzma_filters_free() which can be convenient for freeing the filter options in a filter chain (an array of lzma_filter structures). - lzma_file_info_decoder() to makes it a little easier to get the Index field from .xz files. This helps in getting the uncompressed file size but an easy-to-use random access API is still missing which has existed in XZ for Java for a long time. - Added lzma_microlzma_encoder() and lzma_microlzma_decoder(). It is used by erofs-utils and may be used by others too. The MicroLZMA format is a raw LZMA stream (without end marker) whose first byte (always 0x00) has been replaced with bitwise-negation of the LZMA properties (lc/lp/pb). It was created for use in EROFS but may be used in other contexts as well where it is important to avoid wasting bytes for stream headers or footers. The format is also supported by XZ Embedded (the XZ Embedded version in Linux got MicroLZMA support in Linux 5.16). The MicroLZMA encoder API in liblzma can compress into a fixed-sized output buffer so that as much data is compressed as can be fit into the buffer while still creating a valid MicroLZMA stream. This is needed for EROFS. - Added lzma_lzip_decoder() to decompress the .lz (lzip) file format version 0 and the original unextended version 1 files. Also lzma_auto_decoder() supports .lz files. - lzma_filters_update() can now be used with the multi-threaded encoder (lzma_stream_encoder_mt()) to change the filter chain after LZMA_FULL_BARRIER or LZMA_FULL_FLUSH. - In lzma_options_lzma, allow nice_len = 2 and 3 with the match finders that require at least 3 or 4. Now it is internally rounded up if needed. - CLMUL-based CRC64 on x86-64 and E2K with runtime processor detection. On 32-bit x86 it currently isn't available unless --disable-assembler is used which can make the non-CLMUL CRC64 slower; this might be fixed in the future. - Building with --disable-threads --enable-small is now thread-safe if the compiler supports __attribute__((__constructor__)). * xz: - Using -T0 (--threads=0) will now use multi-threaded encoder even on a single-core system. This is to ensure that output from the same xz binary is identical on both single-core and multi-core systems. - --threads=+1 or -T+1 is now a way to put xz into multi-threaded mode while using only one worker thread. The + is ignored if the number is not 1. - A default soft memory usage limit is now used for compression when -T0 is used and no explicit limit has been specified. This soft limit is used to restrict the number of threads but if the limit is exceeded with even one thread then xz will continue with one thread using the multi-threaded encoder and this limit is ignored. If the number of threads is specified manually then no default limit will be used; this affects only -T0. This change helps on systems that have very many cores and using all of them for xz makes no sense. Previously xz -T0 could run out of memory on such systems because it attempted to reserve memory for too many threads. This also helps with 32-bit builds which don't have a large amount of address space that would be required for many threads. The default soft limit for -T0 is at most 1400 MiB on all 32-bit platforms. - Previously a low value in --memlimit-compress wouldn't cause xz to switch from multi-threaded mode to single-threaded mode if the limit cannot otherwise be met; xz failed instead. Now xz can switch to single-threaded mode and then, if needed, scale down the LZMA2 dictionary size too just like it already did when it was started in single-threaded mode. - The option --no-adjust no longer prevents xz from scaling down the number of threads as that doesn't affect the compressed output (only performance). Now --no-adjust only prevents adjustments that affect compressed output, that is, with --no-adjust xz won't switch from multi-threaded mode to single-threaded mode and won't scale down the LZMA2 dictionary size. - Added a new option --memlimit-mt-decompress=LIMIT. This is used to limit the number of decompressor threads (possibly falling back to single-threaded mode) but it will never make xz refuse to decompress a file. This has a system-specific default value because without any limit xz could end up allocating memory for the whole compressed input file, the whole uncompressed output file, multiple thread-specific decompressor instances and so on. Basically xz could attempt to use an insane amount of memory even with fairly common files. The system-specific default value is currently the same as the one used for compression with -T0. The new option works together with the existing option --memlimit-decompress=LIMIT. The old option sets a hard limit that must not be exceeded (xz will refuse to decompress) while the new option only restricts the number of threads. If the limit set with --memlimit-mt-decompress is greater than the limit set with --memlimit-compress, then the latter value is used also for --memlimit-mt-decompress. - Added new information to the output of xz --info-memory and new fields to the output of xz --robot --info-memory. - In --lzma2=nice=NUMBER allow 2 and 3 with all match finders now that liblzma handles it. - Don't mention endianness for ARM and ARM-Thumb filters in --long-help. The filters only work for little endian instruction encoding but modern ARM processors using big endian data access still use little endian instruction encoding. So the help text was misleading. In contrast, the PowerPC filter is only for big endian 32/64-bit PowerPC code. Little endian PowerPC would need a separate filter. - Added decompression support for the .lz (lzip) file format version 0 and the original unextended version 1. It is autodetected by default. See also the option --format on the xz man page. - Sandboxing enabled by default: * Capsicum (FreeBSD) * pledge(2) (OpenBSD) * Scripts now support the .lz format using xz. * A few new tests were added. * The liblzma-specific tests are now supported in CMake-based builds too ("make test"). module: pkgsrc subject: 'CVS commit: pkgsrc/archivers/xz' unixtime: '1671145375' user: adam
