Release 1.6.3
-------------
. Fixed an underflow error when using flat_xor_hd.
. Added a build option to allow a suffix to be added to library names passed
to dlopen(). To use, define LIBERASURECODE_SO_SUFFIX via CFLAGS when
building. This is useful when renaming libraries for PyEClib wheels, for
example, so they don't conflict with system packages that may be installed.
Release 1.6.2
-------------
. Allow the writing of fragments with the legacy, non-standard CRC-32.
This is intended to smooth upgrades from liberasurecode 1.5.0 and
earlier in a system with multiple readers and writers.
See https://bugs.launchpad.net/liberasurecode/+bug/1886088 for more
information, including a script you can run on already-written
fragments to determine whether you are affected.
If you are affected:
- Before upgrading, ensure every writer will have the environment variable
LIBERASURECODE_WRITE_LEGACY_CRC=1 set upon restart.
- Upgrade liberasurecode on all systems, restarting processes as needed.
Upgraded writers will continue writing CRCs that not-yet-upgraded
readers can use.
- After liberasurecode is upgraded everywhere, remove the environment
variable. zlib CRCs will be used for new writes, and data written with
either CRC will still be readable.
Release 1.6.1
-------------
. Fixed CRC validation of little-endian fragments on big-endian
. Fixed compile warning about unaligned pointers
Release 1.6.0
-------------
. Use zlib for CRC-32
. Allow support for reading of little-endian framents on big-ending
and vice-versa
. Added check to return error for negative data or parity arguments
. Added better argument validation for flat_xor_hd
Release 1.5.0
-------------
. Added support for Phazr.IO libphazr library
. Fixed memory leaks and initialization errors in Jerasure
. Fixed memory leak in ISA-L
. Changed the Galois Field multiplication table in ISA-L to be calculated
only on init.
. Fixed valgrind-check to enable finding memory-leaks.
. Fixed several memory leaks in tests and also in the built-in rs_vand
implementation.
. Fixed warning on automake tool
. Added compiler flag to disable AVX optimizations.
Release 1.4.0
-------------
. Added support for ISA-L Cauchy
. Added get_version functionality to library
. Fixed reconstruct to return an error when memory allocation failed
. Fixed posix_memalign error handling
Release 1.3.1
-------------
. Fixed the internal version number. It was inadvertently skipped in 1.3.0.
Release 1.3.0
-------------
. Fixed error handling on gf_ivnert_matrix in isa-l backend
. Added get_by_desc return value handling to get_fragment_size
. Other minor fixes and updates
Release 1.2.0
-------------
. Add functionality to enable consumers to check which backends are
present on a system
. Fix segfault when fragment index is out of range
. Add fragment metadata checksumming support
Release 1.1.0
-------------
. Fix for a segfault related to Jerasure uninit() function that is being
looked up by the jerasure EC backend (Issue#19)
. Split helpers.h include for backward compatibility
. Create header symlinks in std locations for backward compat (<= 1.0.8)
. Eliminate erasurecode_stdinc.h dependency on log.h
. Move fragment_header defn to main erasurecode header
. doxygen documentation fixes
Release 1.0.9
-------------
. Minor bugfixes including removing offending MAJOR/MINOR version macros
. Enforce upper limit 32 on the number of erasure coding fragments
(#data + #chunks) < 32
Release 1.0.8
-------------
. Introduce 'liberasurecode_rs_vand', a native, software-based Reed-Soloman
Vandermonde backend
. Properly set W in the new internal RS backend. Without this change, the
fragment length passed up is incorrect.
. Remove all GPLv3 m4 references for CPUID checks
. Properly dedupe fragments in fragments_to_string() function
. Prevent backends from reconstructing an index when it is not missing,
ie, is available
. Make ./configure to obey CFLAGS
. Add missing pkg-config templates
. Remove autoconf installed files from git control
. Fix get_supported_flags() arguments
. Properly detect 64-bit architecture.
. Add -f argument to autoreconf to regenerate aclocal macros
. Silent autoconf warning for ac_cv_sizeof_long
. Fix C++ build issues (add missing cplusplus macros definitions)
. Make liberasurecode header installs to a specific include directory
. Fix 'make test' to properly run null and installed backend tests.
. Fix a uint < 0 warning reported by Clang
. Fix memory leak in alg_sig init
. Fix decode when m > k and all parities are chosen as input to decode
