[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 1.3.3, Package name: zstd-1.3.3, Maintainer: pkgsrc-users

Zstd, short for Zstandard, is a fast lossless compression algorithm,
targeting real-time compression scenarios at zlib-level and better
compression ratios.

Log message:
zstd: updated to 1.3.3

perf: improved zstd_opt strategy (levels 16-19)
fix : bug 944 : multithreading with shared ditionary and large data
cli : fix : content size written in header by default
cli : fix : improved LZ4 format support
cli : new : hidden command -b -S, to benchmark multiple files and generate one \ 
result per file
api : change : when setting pledgedSrcSize, use ZSTD_CONTENTSIZE_UNKNOWN macro \ 
value to mean "unknown"
api : fix : support large skippable frames
api : fix : re-using context could result in suboptimal block size in some \ 
corner case scenarios
api : fix : streaming interface was adding a useless 3-bytes null block to small \ 
build: fix : compilation under rhel6 and centos6
build: added check target
build: improved meson support

Log message:
zstd: update to 1.3.2

new : long range mode, using --long command
new : ability to generate and decode magicless frames
changed : maximum nb of threads reduced to 200, to avoid address space \ 
exhaustion in 32-bits mode
fix : multi-threading compression works with custom allocators
fix : ZSTD_sizeof_CStream() was over-evaluating memory usage
fix : a rare compression bug when compression generates very large distances and \ 
bunch of other conditions (only possible at --ultra -22)
fix : 32-bits build can now decode large offsets (levels 21+)
cli : added LZ4 frame support by default
cli : improved --list output
cli : new : can split input file for dictionary training, using command -B#
cli : new : clean operation artefact on Ctrl-C interruption
cli : fix : do not change /dev/null permissions when using command -t with root \ 
cli : fix : write file size in header in multiple-files mode
api : added macro ZSTD_COMPRESSBOUND() for static allocation
api : experimental : new advanced decompression API
api : fix : sizeof_CCtx() used to over-estimate
build: fix : no-multithread variant compiles without pool.c dependency
build: better compatibility with reproducible builds
example : added streaming_memory_usage
license : changed /examples license to BSD + GPLv2
license : fix a few header files to reflect new license

cli : improved and fixed --list command
cli : command -vV lists supported formats
build : fixed binary variants
build : fix Visual compilation for non x86/x64 targets
API exp : breaking change : ZSTD_getframeHeader() provides more information
API exp : breaking change : pinned down values of error codes
doc : fixed huffman example
