Changelog for libblosc1-debuginfo-1.6.1-5.21.x86_64.rpm :

* Fri Aug 07 2015 normandAATTlinux.vnet.ibm.com- Add two patches dragged from fedora to support non-intel archi 0001-Fix-cmake-system-check.patch 0002-Fix-compilation-on-unknown-archs.patch
* Tue May 19 2015 toddrme2178AATTgmail.com- Update to version 1.6.1:
* Fixed a subtle, but long-standing bug in the blosclz codec that could potentially overwrite an area beyond the output buffer.
* Support for runtime detection of AVX2 and SSE2 SIMD instructions, allowing running AVX2 capable c-blosc libraries to run on machines with no AVX2 available (will use SSE2 instead).
* A new blocksize computation allows for better compression ratios for larger typesizes (> 8 bytes), without not penalizing the speed too much (at least on modern CPUs).- changes from version 1.6.0:
* Support for AVX2 is here! The benchmarks with a 4-core Intel Haswell machine tell that both compression and decompression are accelerated around a 10%, reaching peaks of 9.6 GB/s during compression and 26 GB/s during decompression (memcpy() speed for this machine is 7.5 GB/s for writes and 11.7 GB/s for reads). Many thanks to AATTlittlezhou for this nice work.
* Support for HPET (high precision timers) for the `bench` program. This is particularly important for microbenchmarks like bench is doing; since they take so little time to run, the granularity of a less-accurate timer may account for a significant portion of the runtime of the benchmark itself, skewing the results. Thanks to Jack Pappas.- changes from version 1.5.4:
* Updated to LZ4 1.6.0 (r128).
* Fix resource leak in t_blosc. Jack Pappas.
* Better checks during testing. Jack Pappas.
* Dynamically loadable HDF5 filter plugin. Kiyo Masui.- changes from version 1.5.3:
* Use llabs function (where available) instead of abs to avoid truncating the result. Jack Pappas.
* Use C11 aligned_alloc when it\'s available. Jack Pappas.
* Use the built-in stdint.h with MSVC when available. Jack Pappas.
* Only define the __SSE2__ symbol when compiling with MS Visual C++ and targeting x64 or x86 with the correct /arch flag set. This avoids re-defining the symbol which makes other compilers issue warnings. Jack Pappas.
* Reinitializing Blosc during a call to set_nthreads() so as to fix problems with contexts. Francesc Alted.- changes from version 1.5.2:
* Using blosc_compress_ctx() / blosc_decompress_ctx() inside the HDF5 compressor for allowing operation in multiprocess scenarios. See: https://github.com/PyTables/PyTables/issues/412 The drawback of this quick fix is that the Blosc filter will be only able to use a single thread until another solution can be devised.- changes from version 1.5.1:
* Updated to LZ4 1.5.0. Closes #74.
* Added the \'const\' qualifier to non SSE2 shuffle functions. Closes [#75].
* Explicitly call blosc_init() in HDF5 blosc_filter.c, fixing a segfault.
* Quite a few improvements in cmake files for HDF5 support. Thanks to Dana Robinson (The HDF Group).
* Variable \'class\' caused problems compiling the HDF5 filter with g++. Thanks to Laurent Chapon.
* Small improvements on docstrings of c-blosc main functions.- changes from version 1.5.0:
* Added new calls for allowing Blosc to be used
*simultaneously
* (i.e. lock free) from multi-threaded environments. The new functions are: - blosc_compress_ctx(...) - blosc_decompress_ctx(...) See the new docstrings in blosc.h for how to use them. The previous API should be completely unaffected. Thanks to Christopher Speller.
* Optimized copies during BloscLZ decompression. This can make BloscLZ to decompress up to 1.5x faster in some situations.
* LZ4 and LZ4HC compressors updated to version 1.3.1.
* Added an examples directory on how to link apps with Blosc.
* stdlib.h moved from blosc.c to blosc.h as suggested by Rob Lathm.
* Fix a warning for {snappy,lz4}-free compilation. Thanks to Andrew Schaaf.
* Several improvements for CMakeLists.txt (cmake).
* Fixing C99 compatibility warnings. Thanks to Christopher Speller.- specfile:
* update copyright year
* Tue Jul 22 2014 toddrme2178AATTgmail.com- Cleanup .so files
* Tue Jul 22 2014 toddrme2178AATTgmail.com- Use source url so source validation can run.- Change group- Cleanup post and postun
* Thu Jul 17 2014 toddrme2178AATTgmail.com- Update to 1.4.1
* Fixed a bug in blosc_getitem() introduced in 1.4.0. Added a test for blosc_getitem() as well.- Update to 1.4.0
* Support for non-Intel and non-SSE2 architectures has been added. In particular, the Raspberry Pi platform (ARM) has been tested and all tests pass here.
* Architectures requiring strict access alignment are supported as well. Due to this, arquitectures with a high penalty in accessing unaligned data (e.g. Raspberry Pi, ARMv6) can compress up to 2.5x faster.
* LZ4 has been updated to r119 (1.2.0) so as to fix a possible security breach.- Update to 1.3.6
* Updated to LZ4 r118 due to a (highly unlikely) security hole. For details see:
