0.18.2:
This release fixes a memory leak that was introduced in lz4.frame.decompress in 0.18.1. This leak resulted from an incorrect ref count on the returned result which prevented it from ever being released and garbage collected.
v1.8.1.2:
It's the same as v1.8.1, but the version number in source code has been fixed.
The version number is used in cli and documentation display, to create the full name of dynamic library, and can be requested via LZ4_versionNumber().
v1.8.1
perf : faster and stronger ultra modes (levels 10+)
perf : slightly faster compression and decompression speed
perf : fix bad degenerative case
fix : decompression failed when using a combination of extDict + low memory address
cli : support for dictionary compression (-D)
cli : fix : lz4 -d --rm preserves timestamp
cli : fix : do not modify /dev/null permission as root
api : _destSize() variant supported for all compression levels
build : make and make test compatible with -jX
build : can control LZ4LIB_VISIBILITY macro
install: fix man page directory
The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.
There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.
- Generate Zip64 format .zip files when the output is greater than
or equal to 4 GiB.
- Improved gzip options processing and return code compatibility
- Some bug fixes
0.18.1:
This is a minor bugfix release which fixes two small bugs which would result in source references not being released on error conditions in lz4.frame.compress.
0.18.0:
This release changes the strategy for allocating memory to not use undocumented and potentially fragile Python internals (Py_SIZE). This may have a small performance impact, but brings stronger guarantees for future stability.
Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:
pkglint -Cnone,PLIST -Wnone,plist-sort -r -F
0.17.0:
This release fixes a pathological case where compressing and decompressing a zero length bytes object could result in the resulting bytes object causing False to be returned from val == 'b'.
1.4.0 [2017-12-29]
==================
* Improve build with cmake
* Retire autoconf/automake build system
* Add `zip_source_buffer_fragment()`.
* Add support to clone unchanged beginning of archive (instead of rewriting it).
Supported for buffer sources and on Apple File System.
* Add support for Microsoft Universal Windows Platform.
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 frames
build: fix : compilation under rhel6 and centos6
build: added check target
build: improved meson support
This release brings
Huge changes to the LZ4 Frame support which should now be considered beta quality
A new pytest based test harness, and significantly re-worked testing
An end to Python 2.6 support - no testing is currently done against Python 2.6 although the code probably does still work with Python 2.6 at this point in time.
atool is a script for managing file archives of various types (tar,
tar+gzip, zip, etc.). It provides the following commands:
* aunpack: extract an archive, avoiding tar bombs
* apack: create archives or compressed files
* als: list the contents of an archive
* acat: extract to the standard output
* adiff: generate a diff between two archives
* arepack: repack archives to a different format
Optional dependencies: lbzip2 or pbzip2, lzip, plzip, lzop, lzma, zip,
unzip, unrar, lha, unace, arj, arc, nomarch, p7zip, unalz.
Brotli is a generic-purpose lossless compression algorithm that compresses data
using a combination of a modern variant of the LZ77 algorithm, Huffman coding
and 2nd order context modeling, with a compression ratio comparable to the best
currently available general-purpose compression methods. It is similar in speed
with deflate but offers more dense compression.
0.8.1:
Add #includes so compilation on OS X and BSDs works.
0.8.0:
CompressionParameters now has a estimated_compression_context_size() method. zstd.estimate_compression_context_size() is now deprecated and slated for removal.
Implemented a lot of fuzzing tests.
CompressionParameters instances now perform extra validation by calling ZSTD_checkCParams() at construction time.
multi_compress_to_buffer() API for compressing multiple inputs as a single operation, as efficiently as possible.
ZSTD_CStream instances are now used across multiple operations on ZstdCompressor instances, resulting in much better performance for APIs that do streaming.
ZSTD_DStream instances are now used across multiple operations on ZstdDecompressor instances, resulting in much better performance for APIs that do streaming.
train_dictionary() now releases the GIL.
Support for training dictionaries using the COVER algorithm.
multi_decompress_to_buffer() API for decompressing multiple frames as a single operation, as efficiently as possible.
Support for multi-threaded compression.
Disable deprecation warnings when compiling CFFI module.
Fixed memory leak in train_dictionary().
Removed DictParameters type.
train_dictionary() now accepts keyword arguments instead of a DictParameters instance to control dictionary generation.
v1.3.2
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

license : changed /examples license to BSD + GPLv2
license : fix a few header files to reflect new license
py-lz4 provides Python bindings for the LZ4 compression library by Yann
Collet.
At this time the project contains bindings for the LZ4 block format,
which are considered stable.
Support for the LZ4 frame format is a work-in-progress and available as a
technology preview. A future relase will implement support for the LZ4
stream format.
Temporarily remove the zstd buildlink as py-zstandard includes
its own version that it wants to use. Future versions will
support using a system supplied zstd but this one doesn't yet.
Also prevent setup.py from picking up cffi by accident so the
PLIST is stable.
New license : BSD + GPLv2

'--merge' is now able to fix files with thousands of scattered errors
per member by grouping the errors into clusters and then merging the
files as if each cluster were a single error.
The option '-a, --trailing-error' now works with '-l, --list' and
'-D, --range-decompress'.
The output of option '-l, --list' has been simplified to make it easier
to read.
In test mode, lziprecover now continues checking the rest of the files
if any input file is a terminal.
Trailing data are now shown both in hexadecimal and as a string of
printable ASCII characters.
The option '-l, --list' has been ported from lziprecover.
It is now an error to specify two or more different operations in the
command line (--decompress, --list or --test).
Compression time of option '-0' has been slightly reduced.
Decompression time has been reduced by 2%.
In test mode, lzip now continues checking the rest of the files if any
input file is a terminal.

* SDL/Makefile.am: fix generation of sdl-uninstalled.pc that was
not recognized during compilation.
2010-04-05 guidod <guidod@gmx.de>
* Makefile.am: fix "osc rm" and fix "test-sdl" if SDL was not found.
* configure.ac: SDL example builds on pkgconfig/sdl.pc which
was introduced with SDL 1.2.11 - CentOs5 ships 1.2.10 which
does only have "sdl-config" and it made for a mismatch in
in the build configuration: sdl-devel yes, pkgconfig sdl no.

zzip_disk_entry_check_magic to be after the the check that
the seek-value is more than a header's size before the end.
(based on a segfault report by Tulipánt Gergely when the
new modulo_entries code is enabled (which is off by default))

* zzip/Makefile.am: fixing symlinks for lib* - use only for Linux
Thanks to Ryan Schmidt (macports):
... likes to install some symlinks that don't make sense on Mac OS X:
$ ls -l /opt/local/lib/*zzip*so*
lrwxr-xr-x /opt/local/lib/libzzip*.so.10 -> libzzip*.so.13

minitar-cli is a pure-Ruby command-line tool that uses to provide a
command-line tool, minitar, for working with POSIX tar(1) archive
files.
This is release 0.6, extracted from minitar(*) with modernizations.
* https://halostatue.ca/minitar
The minitar library is a pure-Ruby library that provides the ability to deal
with POSIX tar(1) archive files.
This is release 0.6, providing a number of bug fixes including a directory
traversal vulnerability, CVE-2016-10173. This release starts the migration and
modernization of the code:
* the licence has been changed to match the modern Ruby licensing scheme
(Ruby and Simplified BSD instead of Ruby and GNU GPL);
* the +minitar+ command-line program has been separated into the
+minitar-cli+ gem; and
* the +archive-tar-minitar+ gem now points to the +minitar+ and +minitar-cli+
gems and discourages its installation.
Some of these changes may break existing programs that depend on the internal
structure of the minitar library, but every effort has been made to ensure
compatibility; inasmuch as is possible, this compatibility will be maintained
through the release of minitar 1.0 (which will have strong breaking changes).
minitar (previously called Archive::Tar::Minitar) is based heavily on code
originally written by Mauricio Julio Fern\u{e1}ndez Pradier for the rpa-base
project.
Darwin ACL: avoid using mbr_identifier_to_uuid()
Use mbr_uid_to_uuid() and mbr_gid_to_uuid() for backwards compatibility
instead. These functions have been introduced together with membership.h.
This project provides Python bindings for interfacing with the
Zstandard compression library. A C extension and CFFI interface are
provided.
The primary goal of the project is to provide a rich interface to
the underlying C API through a Pythonic interface while not sacrificing
performance. This means exposing most of the features and flexibility
of the C API while not sacrificing usability or safety that Python
provides.
Changes in 2.10 (01 Mar 2017)
* Improve CMake build support.
* Add support for pkg-config.
* Do not redefine "snprintf" so that the examples build with MSVC 2015.
* Assorted cleanups.

-----------------------------
5.2.3 (2016-12-30)
* xz:
- Always close a file before trying to delete it to avoid
problems on some operating system and file system combinations.
- Fixed copying of file timestamps on Windows.
- Added experimental (disabled by default) sandbox support using
Capsicum (FreeBSD >= 10). See --enable-sandbox in INSTALL.
* C99/C11 conformance fixes to liblzma. The issues affected at least
some builds using link-time optimizations.
* Fixed bugs in the rarely-used function lzma_index_dup().
* Use of external SHA-256 code is now disabled by default.
It can still be enabled by passing --enable-external-sha256
to configure. The reasons to disable it by default (see INSTALL
for more details):
- Some OS-specific SHA-256 implementations conflict with
OpenSSL and cause problems in programs that link against both
liblzma and libcrypto. At least FreeBSD 10 and MINIX 3.3.0
are affected.
- The internal SHA-256 is faster than the SHA-256 code in
some operating systems.
* Changed CPU core count detection to use sched_getaffinity() on
GNU/Linux and GNU/kFreeBSD.
* Fixes to the build-system and xz to make xz buildable even when
encoders, decoders, or threading have been disabled from libilzma
using configure options. These fixes added two new #defines to
config.h: HAVE_ENCODERS and HAVE_DECODERS.
--------------------------------------

(pkgsrc-changes)
- Add TEST_TARGET = check
(but make test fails for now)
The contents of FILESDIR may or or may have the user write bit set.
They contain generated files (list.h), and libarchive's build system
recreates these files by opening them for writing without first
removing them.
Discussed on tech-pkg@; thanks to dholland@ for suggesting chmod -R as
both the simplest change and the one least likely to need adjusting.
Zstd, short for Zstandard, is a fast lossless compression algorithm,
targeting real-time compression scenarios at zlib-level and better
compression ratios.

A replacement for the builtin zipfile module, with fast, C-based zipfile
decryption
czipfile is a replacement for Python's builtin "zipfile" module, and provides
much faster, C-based zipfile decryption. The code is actually 95% identical to
Python 2.6.5's Lib/zipfile.py, with some very minor modifications to allow it
to compile in Cython, and the _ZipDecrypter class adapted to take advantage of
native C datatypes.
Package provided by Kimihiro Nonaka in PR 51326, with some cleanups by myself.
(Fix typo in MASTER_SITES, pkglint.)
ocaml 4.03 and the latest framework version. Discussed on packages@ and
OK'd by jperkin.
Changes include:
- Switch to "safe string" mode. Some API functions that use to take
strings now take byte sequences instead. OCaml 4.02 or up is required.
- Update for OCaml 4.03.
- Avoid Zlib error when calling Gzip.output with length = 0.
- Improve support for ZIP files / ZIP file members greater than 2 Gbytes.
v0.3.1 (2016-03-29):
* This release fixes an integer underflow vulnerability in the
code for doing LZH level 3 header decodes (TALOS-CAN-0095).
Thanks go to Marcin Noga and Regina Wilson of Cisco TALOS for
reporting this vulnerability.
- two patches are removed, upstream change
(upstream)
- Updated archivers/gtar to 1.29
Updated archivers/gtar-base to 1.29
Updated archivers/gtar-info to 1.29
------------------------------------
version 1.29 - Sergey Poznyakoff, 2016-05-16
* New options: --verbatim-files-from, --no-verbatim-files-from
The --verbatim-files-from option instructs tar to treat each line read
from a file list as a file name, even if it starts with a dash.
File lists are supplied with the --files-from (-T) option. By
default, each line read from a file list is first stripped off the
leading and trailing whitespace and, if the result begins with a dash,
it is treated as tar command line option.
Use the --verbatim-files-from option to disable this special handling.
This facilitates the use of tar with file lists created automatically
(e.g. by find(1) command).
This option affects all --files-from options that occur after it in
the command line. Its effect is reverted by the
--no-verbatim-files-from option.
* --null option reads file names verbatim
The --null option implies --verbatim-files-from. I.e. each line
read from null-delimited file lists is treated as a file name.
This restores the documented behavior, which was broken in version
1.27.
* New options: --owner-map=FILE and --group-map=FILE
These two options provide fine-grained control over what user/group
names (or IDs) should be mapped when adding files to archive.
For both options, FILE is a plain text file with user or group
mappings. Empty lines are ignored. Comments are introduced with
# sign (unless quoted) and extend to the end of the corresponding
line. Each non-empty line defines translation for a single UID (GID).
It must consist of two fields, delimited by any amount of whitespace:
OLDNAME NEWNAME[:NEWID]
OLDNAME is either a valid user (group) name or a ID prefixed with +. Unless
NEWID is supplied, NEWNAME must also be either a valid name or a
+ID. Otherwise, both NEWNAME and NEWID need not be listed in the
system user database.
* New option --clamp-mtime
The new --clamp-mtime option changes the behavior of --mtime to only
use the time specified if the file mtime is newer than the given time.
The --clamp-mtime option can only be used together with --mtime.
Typical use case is to make builds reproducible: to loose less
information, it's better to keep the original date of an archive,
except for files modified during the build process. In that case, using
reference (and thus reproducible) timestamps for the latter is good
enough.
See <https://wiki.debian.org/ReproducibleBuilds> for more information.
* Deprecated --preserve option removed
* Sparse file detection
Tar now uses SEEK_DATA/SEEK_HOLE on systems that support it. This
allows for considerable speed-up in sparse-file detection.
New option --hole-detection is provided, that allows the user to
select the algorithm used for hole detection. Available arguments
are:
--hole-detection=seek
Use lseek(2) SEEK_DATA and SEEK_HOLE "whence" parameters.
--hole-detection=raw
Scan entire file before storing it to determine where holes
are located.
The default is to use "seek" whenever possible, and fall back to
"raw" otherwise.

Version 2.12 - Sergey Poznyakoff, 2015-09-12
* Improved documentation.
* Manpages are installed by make install.
* New options for copy-out mode:
** --ignore-devno

number.
** --renumber-inodes
Renumber inodes when storing them in the archive.
** --device-independent or --reproducible
Create reproducible archives. This is equivalent to
--ignore-devno --renumber-inodes.

KArchive provides classes for easy reading, creation and manipulation of
"archive" formats like ZIP and TAR.
It also provides transparent compression and decompression of data, like the
GZip format, via a subclass of QIODevice.
Engrampa is a fork of File-Roller.
Engrampa is an archive manager for the MATE environment. This means
that you can create and modify archives; view the content of an archive;
view and modify a file contained in the archive; extract files from the
archive.
Engrampa is only a front-end (a graphical interface) to archiving programs
like tar and zip.

Bmaptool is a generic tool for creating the block map (bmap) for
a file and copying files using the block map. The idea is that
large files, like raw system image files, can be copied or flashed
a lot faster and more reliably with bmaptool than with traditional
tools, like "dd" or "cp".
